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.

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.

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.
