(05/31/2011) Global carbon emissions hit a new high last year proving once again that international political efforts, hampered by bickering, the blame-game, and tepidity, are failing to drive down the greenhouse gas emissions that are causing the planet to heat up. According to the International Energy Agency (IEA), following a slight fall in carbon dioxide emissions due to the economic downturn, emissions again rose to a new record level in 2010: 30.6 gigatons. This is a full 5 percent higher than the past record hit in 2008. The new record puts greater doubt on the international pledge of limiting the global average temperature rise to 2 degrees Celsius.
Environmental law landmark: island nation challenges faraway coal plant for climate impact
(05/25/2011) The far-flung Federated States of Micronesia (FSM), located in the Pacific Ocean, has created legal history by challenging the decision to extend the life of a massive coal plant in the Czech Republic. The over 600-island nation, Micronesia, argues that greenhouse gas emissions from the Czech plant are impacting the way of life in Micronesia, many of whose islands are facing submersion under rising sea levels.
iPhone app uses Google Earth to track climate change impact on redwoods
(05/24/2011) The Save the Redwoods League is partnering with Google Earth Outreach and iNaturalist.org to connect citizens and scientists in an effort to track the effects of climate change on redwood trees and forests.
Nobel laureates: 'we are transgressing planetary boundaries that have kept civilization safe for the past 10,000 years'
(05/23/2011) Last week the 3rd Nobel Laureates Symposium on Global Sustainability concluded with participants—including 17 past Nobel Prize winners and 40 other experts—crafting and signing the Stockholm Memorandum. The document calls for emergency actions to tackle human pressures on the Earth's environment while ensuring a more equitable and just world.
Climate change and deforestation pose risk to Amazon rainforest
(05/20/2011) Deforestation and climate change will likely decimate much of the Amazon rainforest, says a new study by Brazil’s National Institute for Space Research (INPE) and the UK's Met Office Hadley Centre. Climate change and widespread deforestation is expected to cause warmer and drier conditions overall, reducing the resistance of the rainforest ecosystem to natural and human-caused stressors while increasing the frequency of extreme rainfall events and droughts by the end of this century. While climate models show that higher temperatures resulting from global climate change will threaten the resilience of the Amazon, current deforestation is an immediate concern to the rainforest ecosystem and is likely driving regional changes in climate.
US southern forests face bleak future, but is sprawl or the paper industry to blame?
(05/19/2011) More people, less forests: that's the conclusion of a US Forest Service report for forests in the US South. The report predicts that over the next 50 years, the region will lose 23 million acres (9.3 million hectares) largely due to urban sprawl and growing populations amid other factors. Such a loss, representing a decline of over 10 percent, would strain ecosystem services, such as water resources, while potentially imperiling over 1,000 species. However, Dogwood Alliance, which campaigns for conservation of southern forests criticizes the new report for underplaying the role of clearcutting natural forests for the paper industry in the south.
Has the green energy revolution finally arrived?
(05/17/2011) When historians look back at the fight to combat climate change—not to mention the struggle to overcome our global addiction to fossil fuels—will 2011 be considered a watershed moment? Maybe. In the last couple months, three countries—each in the top ten in terms of GDP—have suddenly made major renewable energy promises. Germany, Japan, and, just today, Britain are giving speeches and producing plans that, if successful, could be the global tipping point needed to move beyond fossil fuels to, one day, a world run entirely on green.
NASA Photos: beyond Mississippi flood, southern Africa sees record deluges
(05/12/2011) While record crests of the Mississippi River are creating havoc in the southern US, this is not the only region in the world facing unprecedented flooding. Huge rain events have produced floods in southern Africa as well, impacting Namibia, Botswana, and South Africa. Since last year rainfall has been above average in much of these regions, including a record deluge this month in Namib Desert, where more rain fell in just one day in than usually does in an entire year.
Burning up: warmer world means the rise of megafires
(05/12/2011) Megafires are likely both worsened by and contributing to global climate change, according to a new United Nations report. In the tropics, deforestation is playing a major role in creating giant, unprecedented fires.
Al Gore compares climate change deniers to 'birthers'
(05/03/2011) Former US Vice President, Al Gore, stated in a Time Magazine interview and in a recent presentation that climate change deniers and the so-called birthers—those who refuse to accept that President Obama was born in the US despite clear evidence—are similar. The implication being that both groups are denying clear evidence and creating a "struggle over what is a fact and what is not".
Are US floods, fires linked to climate change?
(04/28/2011) The short answer to the question of whether or not on-going floods in the US Midwest and fires in Texas are linked to a warming Earth is: maybe. The long answer, however, is that while it is difficult—some argue impossible—for scientists to link a single extreme weather event to climate change, climate models have long shown that extreme weather events will both intensify and become more frequent as the world continues to heat up. In other words, the probability of such extreme events increases along with global average temperature.
With pressure to drill, what should be saved in the Arctic?
(04/27/2011) Two major threats face the Arctic: the first is global climate change, which is warming the Arctic twice as fast the global average; the second is industrial expansion into untouched areas. The oil industry is exploring new areas in the Arctic, which they could not have reached before without anthropogenic climate change melting the region’s summer ice; but, of course, the Arctic wouldn't be warming without a hundred years of massive emissions from this very same industry, thus creating a positive feedback loop that is likely to wholly transform the Arctic.
Rising food prices threaten to push over 60 million Asians back into poverty
(04/27/2011) The Asian Development Bank has warned that high food prices on the continent could push 64 million people in developing countries into extreme poverty, reports the AFP.
Obama focuses on climate change in Earth Day proclamation
(04/22/2011) After a long absence of speaking directly to the issue of climate change—he did not mention it once in his State of the Union speech in January—US President Barack Obama used his Earth Day proclamation to focus on it.
What does Nature give us? A special Earth Day article
(04/22/2011) There is no question that Earth has been a giving planet. Everything humans have needed to survive, and thrive, was provided by the natural world around us: food, water, medicine, materials for shelter, and even natural cycles such as climate and nutrients. Scientists have come to term such gifts 'ecosystem services', however the recognition of such services goes back thousands of years, and perhaps even farther if one accepts the caves paintings at Lascaux as evidence. Yet we have so disconnected ourselves from the natural world that it is easy—and often convenient—to forget that nature remains as giving as ever, even as it vanishes bit-by-bit. The rise of technology and industry may have distanced us superficially from nature, but it has not changed our reliance on the natural world: most of what we use and consume on a daily basis remains the product of multitudes of interactions within nature, and many of those interactions are imperiled. Beyond such physical goods, the natural world provides less tangible, but just as important, gifts in terms of beauty, art, and spirituality.
Warmer temperatures may be exterminating pika populations one-by-one
(04/21/2011) The last decade has not been a good one for the American pika (Ochotona princeps) according to a new study in Global Change Biology. Over the past ten years extinction rates have increased by nearly five times for pika populations in the Great Basin region of the US. Examining extinctions of pike populations in the region over the past 110 years, researchers found that nearly half of the extinction events occurred since 1999.
NASA image reveals extent of 2010 Amazon drought
(04/17/2011) NASA has revealed a satellite image of the crippling effect of last year's record-breaking drought on the Amazon ecosystem. For those of you counting, that's two record droughts in the Amazon Basin in 5 years.
Opposition rises against Mekong dam as governments ponder decision
(04/13/2011) As the governments of Laos, Thailand, Cambodia, and Vietnam ready to meet on April 19th to decide whether or not to move forward on the Xayaburi Dam, critics of Mekong River hydroelectric project have warned that the dam will devastate freshwater biodiversity and impact the livelihoods of hundreds of thousands, if not more. Last month a coalition of 263 organizations from 51 countries released a letter in opposition of the dam’s construction.
Gas from 'fracking' not climate friendly
(04/13/2011) It appears every time a fossil fuels industry claims its energy is 'green' or 'climate-friendly', scientists discover this just isn't so. The most recent culprit is natural gas produced by an already controversial method known as hydraulic fracturing, or fracing, which extracts the gas from shale basins. A new study in Climatic Change has found that the process of fracing is worse than coal over a 20-year period and about equal over 100-years. Coal had long been considered the worst climate offender of all energy options.
Antarctic penguins losing to climate change through 80% krill decline
(04/11/2011) Climate change has hit species of Antarctic penguins by causing a staggering decline in their prey: krill. A new study in the Proceedings of the National Academy of Sciences (PNAS) has found that both chinstrap penguins (Pygoscelis antarcticus) and Adélie penguins (Pygoscelis adeliae) have seen their populations decline likely do to less krill, instead of habitat changes. Since 1970 krill populations have fallen by 80% in the Southern Ocean surrounding Antarctica. Because krill require sea ice to reproduce, shrinking sea ice from climate change has made it more difficult for them to breed.
Vanishing mangroves are carbon sequestration powerhouses
(04/05/2011) Mangroves may be the world's most carbon rich forests, according to a new study in Nature Geoscience. Measuring the carbon stored in 25 mangrove forests in the Indo-Pacific region, researchers found that mangroves forests stored up to four times as much carbon as other tropical forests, including rainforests. "Mangroves have long been known as extremely productive ecosystems that cycle carbon quickly, but until now there had been no estimate of how much carbon resides in these systems. That's essential information because when land-use change occurs, much of that standing carbon stock can be released to the atmosphere," explains co-author Daniel Donato, a postdoctoral research ecologist at the Pacific Southwest Research Station in Hilo, Hawaii.
World Bank proposes to limit funding to coal plants
(04/05/2011) Following years of criticism from environmentalists and some governments the World Bank has proposed new rules regarding carbon-intensive coal plants, reports the Guardian. The new rules would allow lending for coal-fired plants only to the world's poorest nations and would only lend after other alternatives, such as renewable energy, had been ruled out.
Carbon labeling good for consumers and business
(03/31/2011) Want to know how many calories are in a serving from that box of cereal? Simply turn it over and you can read a wealth of information: calories, fat, fiber, nutrients. But what if you’d like to know how much carbon was emitted to produce your breakfast? Currently, you're out of luck. But an article in Nature Climate Change argues that labeling products—from food to household products—with their carbon footprint could reduce emissions over time as consumers and companies react to better environmental transparency. A 'carbon footprint' measures the total amount of greenhouse gases emitted to produce a product or service.
'Huge reduction' of water from plants due to higher carbon levels
(03/30/2011) As if ocean acidification and a warming world weren't enough, researchers have outlined another way in which carbon emissions are impacting the planet. A new study shows that higher carbon dioxide levels in the atmosphere have taken a toll on how much water vapor plants release, potentially impacting the rainfall and groundwater sources. A study in the Proceedings of the National Academy of Sciences (PNAS) has found that carbon dioxide levels over the past 150 years has reduced plants' spores, called stomata, by over one third (34%). This is important because stomata take in oxygen and carbon dioxide and release water vapor in a process dubbed 'transpiration'. Less stomata means less water driven into the atmosphere.
Clean energy investments rise 630% in 7 years
(03/29/2011) According to a report by the US Pew Environment Group global clean energy investments, which do not include nuclear power, jumped 630% since 2004. The report detailing 2010 clean energy investments found that China remains the global leader in clean energy, while the US fell from 2nd to 3rd. This is the second year in a row that the US fell: in 2009 it lost first place to China. In all $243 billion were invested in clean energy in 2010.
Last year's drought hit Amazon hard: nearly a million square miles impacted
(03/29/2011) A new study on its way to being published shows that the Amazon rainforest suffered greatly from last year's drought. Employing satellite data and supercomputing technology, researchers have found that the Amazon was likely hit harder by last year's drought than a recent severe drought from 2005. The droughts have supported predictions by the Intergovernmental Panel on Climate Change's (IPCC) that climate change, among other impacts, could push portions of the Amazon to grasslands, devastating the world's greatest rainforest. "The greenness levels of Amazonian vegetation—a measure of its health—decreased dramatically over an area more than three and one-half times the size of Texas and did not recover to normal levels, even after the drought ended in late October 2010," explains the study's lead author Liang Xu of Boston University.
Arctic sea ice maximum ties for lowest on record
(03/24/2011) Providing more data on how climate change is impacting the Arctic, the maximum extent of sea ice this year was tied with 2006 for the lowest on record. Maximum sea ice simply means the territory the sea ice covers at its greatest point before the seasonal melt begins.
As US Republicans officially dismiss climate change, scientists charge them with 'willful ignorance'
(03/17/2011) US Republican congress members officially rejected the widespread scientific consensus that the world is warming and the cause is primarily greenhouse gas emissions. As Republicans in the US House and Commerce Committee voted to stop the US Environmental Protection Agency (EPA) from regulating greenhouse gas emissions, they were also forced to vote on three Democratic amendments asking congress to confirm the science behind climate change. The amendments failed as all 31 Republicans, representing the majority, voted against every amendment, summarily rejecting decades of climate research. However scientists have responded in a particularly scathing opinion piece in Nature, one of the world's most respected scientific journals.
15 conservation issues to watch
(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.
Is Japan's tsunami linked to climate change?
(03/11/2011) Could the earthquake that triggered Japan's devastating tsunami be linked to climate change? The short answer is probably not, but recent research suggests that changing climate has the potential to influence earthquakes in some parts of the world
Republicans believe in climate change but not global warming
(03/09/2011) A new study finds that self-described Republicans are less skeptical of "climate change" than "global warming", reports Miller-McCune.
Melting ice sheets largest contributor to rising sea levels
(03/08/2011) Researchers expected the shrinking ice sheets of Antarctica and Greenland to eventually become the greatest contributor to the world's rising sea levels; they just didn't expect it to happen so quickly. A new study in Geophysical Research Letters has found that ice sheets have overtaken melting glaciers and ice caps.
Birnam Wood in the 21st Century: northern forest invading Arctic tundra as world warms
(03/07/2011) In Shakespeare's play Macbeth the forest of Birnam Wood fulfills a seemingly impossible prophecy by moving to surround the murderous king (the marching trees are helped, of course, by an army of axe-wielding camouflaged Scots). The Arctic tundra may soon feel much like the doomed Macbeth with an army of trees (and invading species) closing in. In a recent study, researchers found that climate change is likely to push the northern forests of the boreal into the Arctic tundra—a trend that is already being confirmed in Alaska.
Coral crisis: 75% of the world's coral reefs in danger
(02/23/2011) Marine scientists have been warning for years that coral reefs, the most biodiverse ecosystems in the ocean, are facing grave peril. But a new comprehensive analysis by the World Resources Institute (WRI) along with twenty-five partners ups the ante, finding that 75% of the world's coral reefs are threatened by local and global impacts, including climate change. An updating of a 1996 report, the new analysis found that threats had increased on 30% of the world's reefs. Clearly conservation efforts during the past decade have failed to save reefs on a large-scale.
Photo gallery: Borneo paradise saved from beachside coal plant
(02/22/2011) Last week the Malaysian government announced it had canceled a plan to build a coal-fired plant in the state of Sabah. The coal plant would have rested on a beach overlooking the Coral Triangle, one of the ocean's most biodiverse ecosystems, and 20 kilometers from Tabin Wildlife Reserve, a rainforest park home to endangered orangutans, Sumatran rhinos, Bornean elephants, and thousands of other species. The cancellation followed a long campaign by a group of environmental and human right organizations dubbed Green SURF (Sabah Unite to Re-power the Future), which argued that the coal plant would have imperiled ecosystems, ended artisanal fishing in the area, hurt tourism, and tarnished Sabah's reputation as a clean-green state.
Coal's true cost in the US: up to half a trillion
(02/20/2011) According to the global market coal is cheap, yet a new study in the Annals of the New York Academy of Sciences finds that the hidden costs of coal are expensive, very expensive. Estimating the hidden costs of coal, such as health and environmental impacts, the study found that burning coal costs the US up to $523 billion a year. Dubbed 'externalities' by economists, the paper argues that these costs are paid by the American public to the tune of $1,698 per person every year.
Environmentalists and locals win fight against coal plant in Borneo
(02/16/2011) Environmentalists, scientists, and locals have won the battle against a controversial coal plant in the Malaysian state of Sabah in northern Borneo. The State and Federal government announced today that they would "pursue other alternative sources of energy, namely gas, to meet Sabah's power supply needs." Proposed for an undeveloped beach on the north-eastern coast of Borneo, critics said the coal plant would have threatened the Coral Triangle, one of the world's most biodiverse marine ecosystems, and Tabin Wildlife Reserve, home to Critically Endangered Sumatran rhinos and Bornean orangutans. Local fishermen feared that discharges from the plant would have imperiled their livelihood.
Not enough data on world's tropical plants to predict impact of warming world
(02/14/2011) How many tropical plant species are threatened by climate change? Which plants have big enough ranges to survive a warming world, not to mention deforestation? How likely is it that the tropics are undergoing a current mass extinction? These questions may appear straight forward, but a new study in Global Change Biology finds that researchers lack the hard data necessary to come to any confident conclusions. According to the study, nine out of ten tropical plants from Africa, Asia, and South America lack the minimum number of collections needed (at least 20) to determine the species' range, and therefore predict the impact of climate change.
Prince Charles: 'direct relationship' between ecosystems and the economy
(02/09/2011) At an EU meeting in Brussels, dubbed the Low Carbon Prosperity Summit, the UK's Prince Charles made the case that without healthy ecosystems, the global economy will suffer.
Food crisis 2011?: drought in China could push food prices even higher
(02/09/2011) The UN's Food and Agriculture Organization (FAO) has warned that a drought in China could devastate the nation's winter wheat crop and further inflate food prices worldwide. Already, food prices hit a record high in January according to the FAO. Rising 3.4 percent since December, prices reached the highest point since tracking began in 1990. While many fear a food crisis similar to the one in 2008-2007, experts say the world has more food in reserve this time around and gasoline, at least for now, remains cheaper. However, if China loses its winter wheat that could scuttle any hopes of avoiding another price rise in crop staples.
Another low record for Arctic ice in January
(02/08/2011) The extent of ice cover in the Arctic for January was the lowest on record, following another record-low in December for that month, according to the National Snow and Ice Data Center (NSIDC).
Numerous causes, including climate change, behind record food prices
(02/07/2011) Food prices hit a record high in January according to the UN's Food and Agriculture Organization (FAO), threatening the world's poor. Rising 3.4% since December, the FAO stated that prices reached the highest point since the agency began tracking food prices in 1990. Given the complexity of world markets and agriculture, experts have pointed to a number of reasons behind the rise including rising meat and dairy consumption, the commodity boom, fresh water scarcity, soil erosion, biofuels, growing human population, and a warming world that has exacerbated extreme weather events like last year's heatwave in Russia.
The ocean crisis: hope in troubled waters, an interview with Carl Safina
(02/07/2011) Being compared—by more than one reviewer—to Henry Thoreau and Rachel Carson would make any nature writer's day. But add in effusive reviews that compare one to a jazz musician, Ernest Hemingway, and Charles Darwin, and you have a sense of the praise heaped on Carl Safina for his newest work, The View from Lazy Point: A Natural Year in an Unnatural World. Like Safina's other books, The View from Lazy Point focuses on the beauty, poetry, and crisis of the world's oceans and its hundreds-of-thousands of unique inhabitants. Taking the reader on a journey around the world—the Arctic, Antarctic, and the tropics—Safina always returns home to take in the view, and write about the wildlife of his home, i.e. Lazy Point, on Long Island. While Safina's newest book addresses the many ways in which the ocean is being degraded, depleted, and ultimately imperiled as a living ecosystem (such as overfishing and climate change) it also tweezes out stories of hope by focusing on how single animals survive, and in turn how nature survives in an increasingly human world. However, what makes Safina's work different than most nature writing is his ability to move seamlessly from contemporary practical problems to the age-old philosophical underpinnings that got us here. By doing so, he points a way forward.
Two massive droughts evidence that climate change is 'playing Russian roulette' with Amazon
(02/03/2011) In 2005 the Amazon rainforest underwent a massive drought that was labeled a one-in-100 year event. The subsequent die-off of trees from the drought released 5 billion tons of CO2. Just five years later another major drought struck. The 2010 drought, which desiccated entire rivers, may have been even worse according to a new study in Science, adding on-the-ground evidence to fears that climate change may inevitably transform the world's greatest rainforest.
From Cambodia to California: the world's top 10 most threatened forests
(02/02/2011) Growing populations, expanding agriculture, commodities such as palm oil and paper, logging, urban sprawl, mining, and other human impacts have pushed many of the world's great forests to the brink. Yet scientists, environmentalists, and even some policymakers increasingly warn that forests are worth more standing than felled. They argue that by safeguarding vulnerable biodiversity, sequestering carbon, controlling erosion, and providing fresh water, forests provide services to humanity, not to mention the unquantifiable importance of having wild places in an increasingly human-modified world. Still, the decline of the world's forests continues: the FAO estimating that around 10 million hectares of tropical forest are lost every year. Of course, some of these forests are more imperiled than others, and a new analysis by Conservation International (CI) has catalogued the world's 10 most threatened forests.
Is Obama's clean energy revolution possible?
(01/26/2011) Last night US President Barack Obama called for a massive green energy make-over of the world's largest economy. Describing the challenge as 'this generation's Sputnik moment' the US president set a goal of producing 80 percent of America's energy by clean sources by 2035. While this may sound improbable, two recent analyses back the president up, arguing that a global clean energy revolution is entirely possible within a few decades using contemporary technology and without breaking the bank. "Based on our findings, there are no technological or economic barriers to converting the entire world to clean, renewable energy sources," Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford said in a press release. "It is a question of whether we have the societal and political will."
Greenland melt is the worst yet
(01/24/2011) Melting of the Greenland ice sheet was the most extreme yet in 2010, beating the previous melt record from 2007. This continues a long-term trend whereby melting in Greenland has increased on average 17,000 square kilometers every year since 1979.
How Genghis Khan cooled the planet
(01/20/2011) In 1206 AD Genghis Khan began the Mongol invasion: a horse-crazed bow-wielding military force that swept through much of modern-day Asia into the Middle East and Eastern Europe. But aside from creating the world's largest empire, the Mongol invasion had another global impact that has remained hidden in history according to new research by Julia Pongratz of the Carnegie Institution's Department of Global Ecology. Genghis Khan and his empire, which lasted nearly two centuries, actually cooled the Earth.
NASA images reveal consistent climate warming among different temperature records
(01/19/2011) New images released by NASA illustrate how four different global temperature records show remarkably consistent warming around the world. Currently, global temperatures are analyzed by four major organizations: NASA Goddard Institute for Space Studies (GISS), NOAA National Climatic Data Center, Met Office Hadley Center’s Climatic Research Unit, and the Japanese Meteorological Agency. Although each organization has garnered slightly different results year-to-year, all show a consistent warming trend globally, including that the most recent decade as the warmest since record-keeping began in the late Nineteenth Century.
2010 ties for the warmest year on record
(01/14/2011) 2010 tied 2005 as the warmest year on record, according to separate analyses by NASA and National Oceanic and Atmospheric Administration (NOAA).
