U.S. gov't gives conditional approval for offshore Arctic drilling
(05/15/2015) Earlier this week, the Bureau of Ocean Energy Management (BOEM) approved Shell Gulf of Mexico Inc.'s multi-year Exploration Plan for the Chukchi Sea off the northern Alaska coast. Environmental groups have raised concerns over the approval, saying drilling in the area threatens wildlife, puts workers at risk, and will further contribute to global warming.
CO2 levels hit monthly average not seen for 2 million years
(05/07/2015) For the first time in human history, carbon dioxide concentrations averaged out at 400 parts per million (ppm) worldwide in March, according to NOAA. Carbon dioxide concentrations have likely not hit such levels in two million years—long before Homo sapiens evolved.
Aru, Mentawai peoples hit the big screen in Oslo
(05/06/2015) A pair of documentaries about small-island indigenous peoples in Indonesia were screened in Oslo on Tuesday as part of a global roadshow leading up to the UN Climate Change Conference to be held in Paris in December. The shorts, "Oil Palm Free Islands" and "The Warden of Jagarian Forest," are part of the If Not Us Than Who series, an initiative of UK-based Handcrafted Films.
World on course to lose 1 in 6 species to climate change – South America, Australia, New Zealand face even more extinctions
(05/04/2015) Renowned biologist E.O Wilson, assessing Earth's sixth great extinction now underway, described the future as a shrinking keyhole through which all species must pass as humanity responds to, and hopefully averts catastrophe. A new study published in the journal Science shows that this keyhole could drastically narrow with each degree increase in global temperature due to climate change.
Keeping up with the climate: efforts to reduce African crop losses face the extra hurdle of climate change
(04/21/2015) The loss of crops to insects, rodents, and mold before they ever reach consumers is a newly recognized problem that governments and development organizations are just starting to address. But as climate change begins to unfold, this job is only getting harder.
Palm oil companies, NGOs endorse new deforestation-limiting toolkit
(04/06/2015) Forests not only house many of the world's species, but also much of its carbon. Now, a toolkit has been developed by a group of companies and organizations with the aim of helping other companies and NGOs identify High Carbon Stock (HCS) forests. The toolkit was endorsed last week by major NGOs and plantation companies in Singapore.
Big surprise in the greenhouse: study finds economic costs of climate change hugely underestimated
(03/30/2015) Look at most climate change projection graphs and you will see a smoothly rising red line of increasing temperature, melting ice and other impacts. But climate does not work that way. Studies of the paleoclimate record indicate that when heat energy is rapidly added to the atmosphere -- as humans are doing today -- the climate can experience “tipping points,” with abrupt shifts and potentially disastrous results.
Record heat in Antarctica
(03/29/2015) The temperature in Antarctica hit a record high last week, reports Weather Underground.
The great Arctic decline: another sea ice record broken
(03/23/2015) Every winter, sea ice in the Arctic expands, providing vital habitat for birthing seals, hunting polar bears, and foraging walruses. But as the Arctic has warmed faster than any place on the planet—due climate change caused by burning fossil fuels—sea ice is not expanding as far as it once did.
Carbon emissions flatlined last year
(03/19/2015) Global carbon emission plateaued last year, according to International Energy Agency, even as the world's economy grew three percent. This is the first time carbon emissions have stalled in the absence of an economic collapse. The news provides tentative hope that the world may finally tackling climate change ahead of much-anticipated climate talks in Paris.
Scientists warn of global warming threat to temperate rainforests
(03/13/2015) In a new study published recently in Earth Systems and Environmental Sciences, researchers warn that temperate rainforests may be in for big changes in the face of global warming, and they recommend reducing greenhouse gas emissions before it's too late.
Study finds soil releases carbon for decades after forests are felled
(03/11/2015) According to a study by researchers with Dartmouth College, the carbon stored in mineral soils, which lie underneath the organic soil layer, is released for decades after a forest is cut down. This may have serious implications for how carbon emissions from deforestation are accounted for.
New study argues the Anthropocene began in 1610
(03/11/2015) In 1610, William Shakespeare began penning one of his greatest plays, The Tempest, which some critics view as a commentary on European colonization of far-away islands and continents. Along those lines, a study today in Nature argues that 1610 is the first year of the human-dominated epoch, known as the Anthropocene, due to the upheavals caused by the 'discovery' of the New World.
Vicious circle: scientists warn peat fires, global warming may intensify each other
(03/10/2015) A new study published recently in Nature Geoscience warns of the consequences of increased smoldering fires as peatlands are drained to make land for agriculture, or dry up due to climate change.
Human impacts are 'decoupling' coral reef ecosystems
(03/09/2015) There is a growing consensus among scientists that we have entered the age of the Anthropocene, or the epoch of humans. In other words, at some point between the 12,000 years separating the beginning of agriculture and the Industrial Revolution, humans became the dominant source of change on the planet, shaping everything from the land to the atmosphere to even the geologic record where we etch our reign.
Bushmeat's dual role: threatened species face off against nutrition and culture
(03/05/2015) Deforestation, habitat destruction, climate change, and other man-made forces are threatening species around the world. But, often overlooked, overhunting is a rising peril to many animals. On the other hand, bushmeat hunting also helps provide vital protein in rural tropical regions and is an important cultural rite for many indigenous tribes. Thus, there is a dual challenge of maintaining food security for forest-dependent populations and ensuring wildlife conservation.
Colombia proposes protected corridor across South America
(03/03/2015) Colombian President Juan Manuel Santos has announced plans to create the world’s largest protected area, stretching from the Atlantic Ocean to the Andes Mountains. Santos plans to propose the protected environmental corridor during the UN climate talks in Paris later this year as a means to combat global warming.
Biofuels are bad news for forests, climate, food security, says report
(02/27/2015) A new report from the World Resources Institute finds that dedicating land to the production of biofuels, a form of renewable energy made from plants, may undermine efforts to achieve a sustainable food future, combat climate change, and protect forests.
One of Brazil’s rarest primates still holds out in single patch of rainforest
(02/26/2015) For many years, particularly after renowned naturalist Philip Hershkovitz of the Field Museum in Chicago published his valuable taxonomy of Neotropical Primates, Saimiri vanzolinii was considered to be a mere subspecies of the larger Bolivian squirrel monkey (Saimiri boliviensis). Today, it has the distinction of being one of the most range-restricted primates in all of the Neotropics.
Arctic upheaval: new book outlines challenges at the top of the world
(02/16/2015) For most of us, the Arctic is not at the front of our minds. We view it as cold, stark, and, most importantly, distant. Yet, even in an age of vast ecological upheaval, one could argue that no biome in the world is changing so rapidly or so irrevocably. Two hundred plus years of burning fossil fuels has warmed up the top of our planet more quickly than anywhere else.
Scientists, NGOs race to save 'Millennium Trees'
(02/12/2015) In a tiny area of an isolated archipelago in the southwest Pacific lives a unique tree species on the precipice of extinction. Recent research has shown it is declining dramatically, and mature individuals may be completely gone in 100 years. In response, environmental organizations and scientists are coming together to try and save New Caledonia's Millennium Trees.
U.S. Central Plains and Southwest will likely face apocalyptic drought
(02/12/2015) In the recent film Interstellar, a mysterious phenomenon known as "the blight" is wiping out agriculture around the world until only corn—for some reason—survives. Humanity is on the brink of starvation. While the blight may be science fiction, global warming is not, and a new study finds that future warming could decimate the western U.S. over the next century.
Pollution from fossil fuels decreased rainfall in Central America
(02/10/2015) Fossil fuel pollution may have caused a southern shift in a vital rainfall belt across Central America, according to a new study in Nature Geoscience, potentially leading to drier conditions and droughts in some northern tropical countries. Using data from a single stalagmite in a Belizean cave, the researchers were able to create an accurate record of both rainfall and temperature for the last 450 years.
Norway sovereign fund drops coal, tar sands, gold-mining companies
(02/09/2015) In its first-ever report on responsible investing, Norway's pension fund announced last week that it has divested from 114 companies in the past three years due to concerns over global warming, deforestation, and sustainability as well as long-term financial viability. Worth a staggering $861 billion, Norway's Government Pension Fund Global (GPFG) is the world's largest sovereign wealth fund.
How termites hold back the desert
(02/05/2015) Some termite species erect massive mounds that look like great temples springing up from the world's savannas and drylands. But aside from their aesthetic appeal—and incredible engineering—new research in Science finds that these structures do something remarkable for the ecosystem: they hold back the desert.
Chemical clues in fossil shells may help us understand today's ocean acidification
(02/04/2015) As atmospheric CO2 levels rise, so too do those in the sea, leading to ocean acidification that outpaces that of any other time in tens of millions of years. Some effects of ocean acidification are imminent, like the fact that calcified organisms such as corals and shellfish will have access to less and less of the chemical components they need to build their shells and skeletons.
The Amazon's oil boom: concessions cover a Chile-sized bloc of rainforest
(02/04/2015) Hungry for oil revenue, governments and fossil fuel companies are moving even further into one of the world's last great wildernesses, according to a new study in the journal Environmental Research Letters. The total area set aside for oil and gas in the Western Amazon has grown by 150,000 square kilometers since 2008, now totaling more than 730,000 square kilometers—an area the size of Chile.
China’s recent forest tenure reforms threaten panda habitat
(01/27/2015) Since the 1950s, plantations and second-growth forests in China have been locally managed by village communities as collective forests, which today account for 58 percent of China's forestland. Many of these collective forests lie within mountainous rural areas, some of which are also home to the 1,600 or so wild giant pandas (Ailuropoda melanoleuca) that survive today.
Accounting for natural capital on financial exchanges
(01/26/2015) Last month, Norway's stock exchange, the Oslo Børs, introduced a way for investors to use their money to promote sustainability. A new list by the stock exchange highlights green bonds, financial products issued by companies to raise capital for environmentally friendly projects. Notably, the list requires that issuing companies obtain and publicize outside opinions on the projects' environmental features.
Conservationists ask, 'Is nuclear the way to go?'
(01/23/2015) Nuclear power at times faces antagonism from the environmental community, with opponents arguing that it produces harmful radioactive waste, leads to the proliferation of nuclear arms, and brings forth lethal disasters. Scientists from Australia say it's time to get past myths about nuclear; they suggest that implementing nuclear power at a larger scale is a positive compromise for fulfilling both energy supply and conservation needs.
Half of Borneo's mammals could lose a third of their habitat by 2080
(01/22/2015) Borneo consistently makes the list of the world’s “biodiversity hotspots” – areas full of a wide variety of forms of life found nowhere else, but which are also under threat. To better understand the hazards, a study published today in the journal Current Biology examines the effects of climate change and deforestation in the coming decades on mammals living on the island.
Endangered chimp habitat under threat from climate change
(01/22/2015) Climate change could make life more difficult for the world’s rarest chimp subspecies, the Nigerian-Cameroon chimpanzee, reported a team of scientists in the journal BMC Evolutionary Biology earlier this week.
Changing California forests may help us prepare for the future
(01/21/2015) A new study published by the Proceedings of the National Academy of Sciences examines how California’s forests have changed since the 1930s--and, according to its authors, can help us understand how forests will respond to the changing global climate in the future.
Even with no El Nino, 2014 was the warmest year on record
(01/18/2015) On Friday both NASA and NOAA announced that last year—2014—was the warmest on record. The year bested out both previous record holders, 2005 and 2010. According to NOAA, 2014 was 0.69 degrees Celsius (1.24 degrees Fahrenheit) above the 20th century average. The Earth is warming rapidly due to greenhouse gas emissions, mostly from burning fossil fuels such as coal, oil, and gas.
Fishing industry could lose up to $41 billion due to climate change
(01/16/2015) Climate change is already having a severe impact on the atmosphere and oceans around the world. These changes are also impacting specific economic sectors including the fishing and aquaculture industries. According to a recent report by the European Climate Foundation, the Sustainable Fisheries Partnership and the University of Cambridge, the fishing industry is projected to lose tens-of-billions as the world continues to heat up.
Empty seas? Scientists warn of an industrialized ocean
(01/15/2015) This is obvious, but still important: humans are not a marine species. Even as we have colonized most of our planet's terrestrial landscapes, we have not yet colonized the oceans. And for most of our history, we have impacted them only on the periphery. A new review in Science finds that this has saved marine species and ecosystems from large-scale damage—that is, until the last couple centuries.
Top 10 HAPPY environmental stories of 2014
(12/29/2014) In what was widely seen as a possible breakthrough in the battle to coordinate some kind of response to global warming, China and the U.S. announced joint actions this year. On November 12th, the world's two most powerful countries surprised pretty much everyone by announcing that they would work together to tackle the crisis.
Top 10 Environmental Stories of 2014
(12/23/2014) In 2014, the unimaginable happened: companies representing the majority of palm oil production and trade agreed to stop cutting down rainforests and draining peatlands for new oil palm plantations. After years of intense campaigning by environmentalists and dire warnings from scientists, nearly two dozen major producers, traders, and buyers established zero deforestation policies.
Children 'clean' oil spill with kitchen utensils in the Sundarbans
(12/15/2014) On December 9th, a tanker slammed into another vessel along the Shela River in the world's largest mangrove forest: the Sundarbans in Bangladesh. The tanker sank, spilling an estimated 75,000 gallons (350,000 liters) of fuel oil into waterways that are a part of a reserve for threatened Ganges river dolphins and Irrawaddy dolphins.
Reefs reduce 97 percent of wave energy, could be better than artificial barriers
(12/15/2014) We have a lot of stake in the coast. Coastal waters are where we host fisheries, build homes and turn to for tourism and recreation. So how should coastal communities, which comprise nearly 40 percent of the world's population, safeguard against flooding, erosion and violent weather? Marine scientist Michael Beck suggests the solution is growing right beneath some waves and, in many cases, it has been waiting there for thousands of years.
Bamboo could help fight global warming
(12/11/2014) Restoring degraded land and forests with the world’s fastest growing plant, bamboo, can contribute to major carbon emission reductions. This is according to a new report that discusses the massive potential of bamboo in fighting global warming, with bamboo forests projected to store more than one million tons of carbon by 2050 in China alone.
Indigenous leader murdered before he could attend Climate Summit
(12/08/2014) Days before José Isidro Tendetza Antún was supposed to travel to the UN Climate Summit in Lima to publicly file a complaint against a massive mining operation, he went missing. Now, the Guardian reports that the body of the Shuar indigenous leader has been found, bound and buried in an unmarked grave on the banks of the Zamora River.
Biodiversity protection is key to REDD+ success, study shows
(12/05/2014) Protecting biodiversity may be crucial for successfully storing carbon in forests, scientists say. A recent publication on Oryx - The International Journal of Conservation suggests that biodiversity loss –especially through hunting – will hinder the success of Reducing Emissions from Deforestation and Forest Degradation (REDD) projects.
One-two punch: farming, global warming destroying unique East African forests
(12/03/2014) Lush mountains speckle East Africa's grasslands and desert, from Mozambique to Ethiopia. These isolated habitats are home to a plethora of species, and are considered by scientists to be some of the most biodiverse regions in the world. However, their forests are being cut down for farmland and are threatened by global warming, putting at risk multitudes of species that have nowhere else to go.
Threatened indigenous forests store more than half the Amazon's carbon
(12/02/2014) A new study released today finds the total carbon load locked up in parts of the Amazon rainforest held by indigenous groups to be much higher than previously estimated – an amount that, if released, would be capable of destabilizing the earth’s atmosphere. But because of flimsy land rights, these areas stand at risk of deforestation.
Shark pups may not survive climate change
(12/01/2014) Fierce predatory sharks rule the oceans from the apex of the food pyramid. But climate change may be tougher than these marine hunters, a new study suggests. As oceans warm and their waters become more acidic, fewer sharks may survive their infancies.
A tale of 2 Perus: Climate Summit host, 57 murdered environmentalists
(11/18/2014) On September 1st, indigenous activist, Edwin Chota, and three other indigenous leaders were gunned down and their bodies thrown into rivers. Chota, an internationally-known leader of the Asháninka in Peru, had warned several times that his life was on the line for his vocal stance against the destruction of his peoples' forests, yet the Peruvian government did nothing to protect him—or others.
Ending deforestation won't stop carbon emissions from land use change
(11/17/2014) Even if the world stopped cutting down forests, carbon dioxide emissions from land use change would still pose a major challenge, according to a new paper in Nature Climate Change. The research finds that eliminating deforestation would mean agriculture would be pushed into non-forest ecosystems and still release significant quantities of carbon dioxide.
Green Climate Fund nears $7 billion after U.S. pledges $3 billion
(11/17/2014) The Green Climate Fund (GCF) is suddenly looking very lively after two announcements over the weekend. The U.S. has announced an initial pledge of $3 billion to the fund, while Japan pledged $1.5 billion. This more than doubles the current amount pledged to the key fund, which is now around $6.94 billion from thirteen countries. The new pledges also bring the fund much closer to an initial goal of $10-15 billion.
Leaf bacteria are important to tree health, may help forests adapt to climate change
(11/13/2014) Leaves are vital trees organs that support many important functions. A recent study published in PNAS found that each tree species in tropical rainforests possesses distinctive bacterial communities – called microbiomes – on their leaves. Understanding how leaf microbiomes vary among species may in the future be applied for maintaining healthy forests and predicting how forests will react to climate change.
Prelude to Paris: China and U.S. surprise world with joint climate deal
(11/12/2014) In what will likely have major ramifications for a new climate agreement in Paris in 2015, China and the U.S. surprised everyone today by announcing a joint climate deal. At a press conference in Beijing, China President, Xi Jingping, and U.S. President, Barack Obama, outlined climate actions for both juggernauts up to 2030.
New birds arise due to emigration not separation
(11/11/2014) A bird's eye view of speciation in the Neotropics. How long does it take for a new species to develop? Not long, it turns out. In fact, only a few thousand years — an evolutionary blink of an eye. A recent article published in Nature tracked neotropical bird speciation, or the process by which new species emerge.
Poor rains then floods lead to food crisis in Somalia
(11/11/2014) Four years after over a quarter of a million people perished in a famine in Somalia, the East African country is again on the verge of a possible humanitarian disaster. Flooding in southern Somalia, following months of little rain, has just exacerbated an already-precarious situation according to the Food and Agricultural Organization (FAO).
Can we stop runaway global warming? 'All we need is the will to change'
(11/03/2014) Twenty-six years after the founding of the IPCC, the Nobel Prize-winning group of scientists has released a new synthesis report that warns in its strongest tones yet that climate change must be dealt with. None of the findings are surprising—they have been released in earlier assessments throughout the year—but the terms in which they are written are the starkest yet.
Amazon rainforest is getting drier, confirms another study
(10/30/2014) Parts of the Amazon rainforest are getting considerably less rain, leading trees to absorb less carbon, finds a study published this week in the journal Proceedings of the National Academy of Sciences.
Will 2014 be the warmest year on record?
(10/29/2014) With the news that September was the warmest on record globally, 2014 takes one step closer to being the warmest year since record-keeping began in the late 19th Century. Last week, NOAA announced that September was 0.72 degrees Celsius (1.30 degrees Fahrenheit) above the 20th Century average, not only making it the hottest yet, but further pushing 2014 past the current ceiling.
Artists, musicians, writers protest government plans for massive coal plant in the Sundarbans
(10/28/2014) Over the weekend, Bangladeshi artists performed plays, sang songs, and recited poetry all in a bid to protect the Sundarbans—the world's biggest mangrove forest—from the threat of a massive coal plant. Construction is already under way on the hugely controversial Rampal coal plant, a 1,320 megawatt plant set just 14 kilometers from the edge of the Sundarbans.
Coal, climate and orangutans – Indonesia’s quandary
(10/21/2014) What do the climate and orangutans have in common? They are both threatened by coal - the first by burning it, and the second by mining it. At the recent United Nations Climate Summit in New York, world leaders and multinational corporations pledged a variety of actions to reduce greenhouse gas emissions and deforestation to avert a looming disaster caused by global warming.
Could California be facing a mega-drought?
(10/13/2014) Scientists and politicians, everyone agrees: California is in deep trouble. As the state enters its fourth year of drought and the soil has never been drier. Some look at the sky with hope that El Niño will bring much needed rain. But most are starting to wonder if this is just the beginning. Are we entering a mega-drought that could last for more than a decade?
Forest fragmentation's carbon bomb: 736 million tonnes C02 annually
(10/09/2014) Scientists have long known that forest fragments are not the same ecologically as intact forest landscapes. When forests are slashed into fragments, winds dry out the edges leading to dying trees and rising temperatures. Biodiversity often drops, while local extinctions rise and big animals vanish. Now, a new study finds another worrisome impact of forest fragmentation: carbon emissions.
The only solution for polar bears: 'stop the rise in CO2 and other greenhouse gases'
(10/08/2014) Steven Amstrup, Chief Scientist for Polar Bears International, has worked diligently on polar bears for over 30 years. He radio-collared some of the first bears and discovered that annual activity areas for 75 tracked females averaged at a stunning 149,000 square kilometers. His recent work highlighted the cost of global warming to these incredible animals and the sea ice they so closely depend on.
Throng of 35,000 walruses is largest ever recorded on land, sign of warming arctic
(10/01/2014) A mass of thousands of walruses were spotted hauled up on land in northwest Alaska during NOAA aerial surveys earlier this week. An estimated 35,000 occupied a single beach – a record number illustrating a trend in an unnatural behavior scientists say is due to global warming.
Turning point for Peru's forests? Norway and Germany put muscle and money behind ambitious agreement
(09/24/2014) From the Andes to the Amazon, Peru houses some of the world's most spectacular forests. Proud and culturally-diverse indigenous tribes inhabit the interiors of the Peruvian Amazon, including some that have chosen little contact with the outside world. And even as scientists have identified tens-of-thousands of species that make their homes from the leaf litter to the canopy.
Towards the poles: tropical cyclones on the move
(09/24/2014) If you thought your relatively northerly or southerly location sheltered you from Mother Nature’s worst storms, think again. For years we have known that the tropics are expanding towards the poles. However, there is something decidedly destructive accompanying that shifting warm weather: tropical cyclones.
Norway to pay Liberia to stop deforestation
(09/23/2014) In one of the many major announcements that have come out of the UN Climate Summit in New York this week, Norway says it will pay Liberia to stop cutting down its forests. Norway’s payment will come on the form of development aid for the war-torn, impoverished, and now Ebola-ridden West African nation.
Leonard DiCaprio to UN Climate Summit: 'You can make history or you will be vilified by it'
(09/23/2014) Actor, environmental activist, and recently named UN Messenger of Peace, Leonardo DiCaprio, spoke today to a UN Climate Summit. The summit, which is hosting the largest gathering of world leaders to address the crisis in five years, is meant to pave the way for a new climate agreement in Paris in 2015.
Climate coup: Rockefeller announces they are dropping fossil fuel investments
(09/22/2014) In 1870, John D. Rockefeller founded the Standard Oil Company. Rapidly becoming the world's largest oil refiner, Standard made Rockefeller a billionaire and one of the world's greatest philanthropists. 144 years later and John D. Rockefeller's descendants have announced they are stripping fossil fuels from the Rockefeller Brothers Fund, a private charity with around $860 million in assets.
Chinese now emit more carbon per capita than Europeans
(09/22/2014) Last year, the people of China emitted more carbon per person than those in the EU, according this year's Global Carbon Budget. The report, updated annually, also found that global emissions jumped 2.5 percent last year and are set to hit a record high of 40 billion tonnes this year. The findings highlight how little global society has done to stem emissions, despite numerous pledges and past global agreements.
Over half a million people march for climate action worldwide, shattering turnout predictions
(09/22/2014) Around 570,000 people took part in marches around the world yesterday calling for action on climate change. By far the largest event was in New York City, which had been dubbed the biggest climate march in history weeks before. Organizers estimate that 400,000 people showed up to the march in Manhattan, shattering predictions.
Scientists rebut NYTimes op-ed 'To Save the Planet, Don’t Plant Trees'
(09/22/2014) The following is a response from a group of scientists' -- including 6 members of the National Academy, 3 IPCC Lead Authors, and 1 IPCC Co-Chair -- to Dr. Nadine Unger’s September 21, New York Times Op-Ed, "To Save the Planet, Don’t Plant Trees"
Changing climate, changing conservation paradigms in Canada's boreal forests
(09/19/2014) Crackling heat and thick billowing smoke raced across the landscape. After weeks of scorching dry summer weather, the wildfire seemed to hungrily consume the earth. In northern Alberta, Canada, the Richardson fire of 2011 gained particular notoriety for ravaging nearly 700,000 hectares – and threatening the Athabasca oil sand development. Yet it is these very wildfires that are so crucial in shaping our boreal forests – which make up nearly one third of the world's forests.
World population could surpass 13 BILLION by the end of the century
(09/18/2014) By 2100, over 13 billion people could be walking the planet. That's the conclusion of a new study published today in Science, which employed UN data to explore the probability of various population scenarios. The new study further demolishes the long-held theory that human population growth will quit growing by mid-century and then fall.
The cheap option on climate change: recognize indigenous rights to forests
(09/18/2014) Since 2008, governments have invested $1.64 billion in funds to kick-start REDD+, or Reducing Emissions from Deforestation and Degradation, the global effort to conserve the world's forests in order to better mitigate climate change. However, a new report by the Rights and Resources Initiative (RRI) finds that same amount of money could have secured the legal rights of indigenous and local people to 450 million hectares of forest, an area 40 percent larger than India.
'We will win this war': Yeb Saño speaks out on global warming
(09/17/2014) Ahead of the upcoming Climate Change Summit to be held in New York, September 23, a Filipino man who last year made headlines around the world on the subject is speaking out.
'We are running out of time': CO2 concentrations in the atmosphere surprise scientists
(09/10/2014) The concentration of carbon dioxide in the atmosphere made the biggest jump last year since 1984, according to the World Meteorological Organization's (WMO) Greenhouse Gas Bulletin, raising alarm bells about society's inaction on curbing global warming.
Thought wiped out by climate change, 'extinct' snail rediscovered in Seychelles
(09/09/2014) The Aldabra banded snail was declared extinct in 1997 as one of the world’s first recorded direct casualties of climate change. But last month, a monitoring team found a population on one of the atoll’s islands, surprising the team and giving hope that other species whose habitats are being degraded by climate change may still be able to cling to existence.
Australia cancels plan to dump dredge in Great Barrier Reef
(09/02/2014) A consortium of companies—North Queensland Bulk Ports, GVK Hancock and Adani Group—have announced they are giving up on a hugely-controversial plan to dump five million tonnes of dredged sediment in the Great Barrier Reef. The plans ran into considerable opposition from environment, conservation, and tourism groups who feared harm to the world's largest coral reef system.
More trouble with tar sands: oil extraction leading to big forest loss in Alberta
(08/29/2014) Tar sands operations have been the subject of much controversy over the past few years as expected economic gains for Canada the may come at the cost of environmental damage from the proposed Keystone XL pipeline and increased greenhouse gas emissions. Now another negative impact has come to light - deforestation of the boreal forest overlying the oil deposits.
An uncertain future: world's last wild Siberian tigers threatened by illegal logging, global warming, disease (PART II)
(08/22/2014) Every year, between 20 and 30 tigers are poached. Illegal logging is reducing the tigers' habitat, and illegal hunting is reducing its food supply. However, these are not the only threats to wild tiger survival -- other problems are cropping up and taking a toll on the iconic big cat.
Planting meadows in the ocean: technique may help restore disappearing seagrass beds
(08/11/2014) Eelgrass is an important part of many ocean ecosystems, but is disappearing due to human impacts. However, a study published recently in found eelgrass beds could benefit from a restoration technique using seed-filled pearl nets.
Indonesia's children see ravaged environment in their future
(08/11/2014) A generation ago, Borneo was one of the wildest places on the planet. But decades of logging and oil palm plantations has changed the landscape of Borneo forever: in fact a recent study found that the island has lost 30 percent of its total forest cover since 1973. In the face of this large-scale environmental destruction, a new study finds that Indonesian Borneo's children have a pessimistic view of their future.
Featured video: new documentary highlights the Long March to save the Sundarbans
(08/05/2014) Last fall tens of thousands of Bangladeshis participated in a five day march that took them from the country's capital to the Sundarbans, the world's largest mangrove forest. They marched to protest the proposal to build a coal plant on the edge of the great wetland. Filmmaker, Bratto Amin, was there.
Biomass burning accounts for 18% of CO2 emissions, kills a quarter of a million people annually
(08/05/2014) Biomass burning takes many forms: wildfires, slash-and-burn agriculture, clearing forests and other vegetation, and even industrialized burning for energy production. Yet this burning—mostly manmade but also natural—takes a massive toll both on human health and the environment.
True stewards: new report says local communities key to saving forests, curbing global warming
(07/24/2014) Deforestation is compromising forests around the world, destroying vital habitat and causing greenhouse gases emissions that are contributing to global warming. A new report released today finds a possible solution: protecting forests by empowering the local communities that live within them.
Desperate measures: researchers say radical approaches needed to beat extinctions
(07/24/2014) Today, in the midst of what has been termed the “Sixth Great Extinction” by many in the scientific community, humans are contributing to dizzying rates of species loss and ecosystem changes. A new analysis suggests the time may have come to start widely applying intensive, controversial methods currently used only as “last resort” strategies to save the word’s most imperiled species.
Peru slashes environmental protections to attract more mining and fossil fuel investment
(07/23/2014) In an effort to kickstart investment in mining and fossil fuels, Peru has passed a controversial law that overturns many of its environmental protections and essentially defangs its Ministry of Environment. The new law has environmentalists not only concerned about its impact on the country but also that the measures will undermine progress at the up-coming UN Climate Summit in December.
'A high price to pay': new Indonesian peatland regulation may do more harm than good
(07/22/2014) The Government Regulation on Peatland Ecosystem Protection and Management, initially drafted by the Ministry of Forestry in 2013, is getting mixed acceptance from civil society. On one hand, the regulation would offer more protection to the country’s vast peatland areas. However, on the other, some NGOs have slammed the draft as a potential source of new conflicts for local people.
Germany tops energy efficiency rating while U.S. remains stuck near the bottom
(07/21/2014) Two years after the first energy efficiency ranking report put out by the American Council for an Energy-Efficient Economy (ACEEE), and the U.S. still lags widely behind most of the world's other large economies. In the second report, the U.S. came in at number 13 out of 16 nations—even beaten by new-comer to the report, India—while Germany took the top spot.
Two years after coming into effect, Australia kills carbon tax
(07/17/2014) In a significant victory for Prime Minister Tony Abbott, the Australian Senate has voted to repeal the country's two-year-old carbon tax. Abbott made dismantling the tax one of the cornerstones of his campaign last September even as Australia remains one of the highest carbon emitters per capita in the industrialized world.
Scientists can now accurately count polar bears...from space
(07/17/2014) Polar bears are big animals. As the world's largest land predators, a single male can weigh over a staggering 700 kilograms (about 1,500 pounds). But as impressive as they are, it's difficult to imagine counting polar bears from space. Still, this is exactly what scientists have done according to a new paper in the open-access journal PLOS ONE.
Attack of the killer vines: lianas taking over forests in Panama
(07/14/2014) A worrying trend has emerged in tropical forests: lianas, woody long-stemmed vines, are increasingly displacing trees, thereby reducing forests’ overall ability to store carbon. The study, recently published in Ecology, found several detrimental effects of increased liana presence.
A garden or a wilderness? One-fifth of the Amazon may have been savannah before the arrival of Europeans
(07/09/2014) The Amazon is the largest tropical forest on the planet, covering about 6.5 million square kilometers, although much has been lost in recent decades.Yet new research published in the Proceedings of the National Academy of Sciences (PNAS) finds that quite recently—just 500 years ago—a significant portion of the southern Amazon was not the tall-canopied forest it is today, but savannah.
Climate-linked drought cutting forests' carbon-storing ability
(07/08/2014) Climate extremes are dramatically cutting the ability of trees to sequester carbon, threatening to convert some forests from carbon sinks into carbon sources, finds a study published this month in Environmental Research Letters.
Booming populations, rising economies, threatened biodiversity: the tropics will never be the same
(07/07/2014) For those living either north or south of the tropics, images of this green ring around the Earth's equator often include verdant rainforests, exotic animals, and unchanging weather; but they may also be of entrenched poverty, unstable governments, and appalling environmental destruction. A massive new report, The State of the Tropics, however, finds that the truth is far more complicated.
Next big idea in forest conservation? The 'double-edged sword' of democracy
(07/03/2014) Dr. Douglas Sheil considers himself an ecologist, but his research includes both conservation and management of tropical forests. Currently teaching at the Norwegian University of Life Sciences (NMBU) Sheil has authored and co-authored over 200 publications including scholarly articles, books, and popular articles on the subject.
Unrelenting population growth driving global warming, mass extinction
(06/26/2014) It took humans around 200,000 years to reach a global population of one billion. But, in two hundred years we've septupled that. In fact, over the last 40 years we've added an extra billion approximately every dozen years. And the United Nations predicts we'll add another four billion—for a total of 11 billion—by century's end.
Super warm oceans make May the hottest on record
(06/26/2014) Last month was the warmest May on record, according to new data from the National Oceanic and Atmospheric Administration (NOAA). While global land surface temperatures were the fourth warmest, it was the ocean surface where things really heated up.
Global warming puts trillions at stake, but mitigation offers big economic gains
(06/25/2014) Two new reports this week look at the economics of global warming. The first, Risky Business, tallies the cost of climate change to the U.S., including tens-of-billions lost to destruction of coastal property, crop failures, drought, wildfires, and heatwaves. In contrast, the second report, by the World Bank, turns climate change economics on its head.
Study finds tiny cloud forests have big biodiversity
(06/24/2014) Tropical cloud forests are situated in mountains and are characterized by the frequent presence of low-level clouds. Scientists have always regarded them as having high biodiversity, but a recent study adds a new dimension: it found cloud forests contain a significant and surprising array of tree and bromeliad species, even when they are relatively small.
'Borne by the rest of the world': deforestation has global impact, reduces food security
(06/13/2014) Research indicates that areas with more forest cover tend to have superior food resilience compared to areas with less. In addition, the loss of forest cover to deforestation has long-term impacts not only locally, but also globally. These topics were discussed by international experts during the 2020 Conference on Building Resilience for Food and Nutrition Security, held last month in Addis Ababa, Ethiopia.
