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.
What's an environmental journalist to do with so much good news?
(06/12/2014) As an environmental journalist covering stories from the great Arctic ice melt to the rhino poaching crisis in Africa, you'll forgive me if sometimes in the morning—before I turn my computer on—I have a sudden desire to spend a few extra minutes in bed or have a leisurely breakfast with my daughter or just sit in the back yard with a cup of tea and a good book.
EPA carbon proposal may be crucial step in addressing global climate change
(06/10/2014) The U.S. Environmental Protection Agency's (EPA) June 2nd regulation proposal hit all the expected chords. Following on the heels of a January regulation for new power plants, the Clean Power Plan focuses on all existing electric generation. By 2030, the plan aims to reduce 2005-level carbon dioxide emissions by 30 percent.
Tree-huggers: koalas cuddle up to keep cool
(06/06/2014) For animals that live in places that are both hot and dry, using valuable water stores to cool off via evaporation may put them at risk of dehydration. Now, as described in a new study published in Biology Letters, it seems that koalas have figured out a way to stay both cool and dry: by hugging trees.
Ignoring boreal forests could speed up global warming
(06/04/2014) Greenhouse gas emissions from human activity have caused global air and sea surface temperatures to rise approximately 0.8 Celsius (1.4 degrees Fahrenheit) since the beginning of the 20th century, contributing to a plethora of problems worldwide from rising sea levels to desertification. A new study finds that global temperatures may start to increase even faster if more is not done to protect Earth’s boreal forests.
April 2014: 350th month in a row with temperatures above average
(06/04/2014) This April was notable for being the 350th month in a row where temperatures exceeded the 20th Century average. This means, monthly global temperatures have not fallen below average for even a single month since February 1985.
Turning point? U.S. and China announce major actions on global warming
(06/03/2014) Could 2014 be a turning point for efforts to slash global greenhouse gas emissions? Maybe: in less than 24 hours the world's two largest emitters of carbon dioxide announced plans to finally rein-in the gas most responsible for global warming.
Animals bark, screech, and howl for action on global warming (PHOTOS)
(06/02/2014) On May 22nd, zoos and aquariums around the world creatively called for action on global warming. Dubbed 'Show the Wild Face of Climate Change,' the event involved over 70 institutions from 25 countries on all seven continents.
Upcoming EPA Proposal could put America back on track to lead on global warming
(05/27/2014) A regulation proposal on coal plants that the U.S. Environmental Protection Agency (EPA) will release in June could be great news for the climate change initiative. The EPA rolled out tough regulations on new constructions of electric generation facilities in January, but the nation's 1,500 existing power plants were left unaffected.
April ties for warmest on record
(05/27/2014) Globally, this April was a scorcher, tying with 2010 for the warmest April on record, according to new data released by the National Oceanic and Atmospheric Administration (NOAA) last week. This makes 2014, to date, the sixth warmest year on record going back to 1880 when comparing the first four months.
Extreme cold and drought in U.S. linked to climate change
(05/23/2014) The U.S. Midwest and Northeast experienced one of the coldest, snowiest winters on record this past season. This might seem contrary to warming trends forecast by climate scientists, but a new analysis released today in Science points out that climate change caused by greenhouse gas emissions may actually have contributed to the well-below average temperatures seen in parts of the U.S.
Climate change's ominous secret
(05/21/2014) Climate change is happening and humans are causing it, primarily from the increase in atmospheric carbon dioxide caused by burning fossil fuels. This much we know. The 'secret' comes from changes happening in the fast-warming Arctic: we may be surprisingly close to an Earth that supports far fewer humans than it does today.
Tipping point already reached? West Antarctica in slow-motion, unstoppable melt
(05/14/2014) Two hundred years from now, the planet could look very different. This week two landmark studies revealed that West Antarctica's ice sheet is in a state of seemingly inevitable collapse linked to climate change. The slow-motion collapse would by itself eventually lead to a rise in global levels of 3.6-4.5 meters (12-15 feet).
Featured video: John Oliver skewers media 'balance' on climate science in viral video
(05/13/2014) Sometimes you need comedians to tell the truth. On his new show, Last Week Tonight, comedian John Oliver took on the poor state of media reporting on climate science.
Underwater horrors: shells of marine life melting off the coast of the U.S.
(05/08/2014) It could be the plot of a horror movie: humans wake up one day to discover that chemical changes in the atmosphere are dissolving away parts of their bodies. But for small marine life known as sea butterflies, or pteropods, this is what's happening off the West Cost of the U.S. Increased carbon in the ocean is melting away shells of sea butterflies.
Stanford kicks coal out of its $18 billion endowment
(05/07/2014) The fossil fuel divestment campaign won a major victory today as Stanford University announced it would drop coal companies from its massive $18.7 billion endowment, the fourth largest of any American university. The action follows a petition by student group Fossil Free Stanford and five months of research by Stanford's Advisory Panel on Investment Responsibility and Licensing.
Cosmos's Neil deGrasse Tyson on climate change: 'What's our excuse?'
(05/06/2014) America's favorite astrophysicist, Neil deGrasse Tyson, tackled climate change on the most recent episode of the hit show, Cosmos: A Spacetime Odyssey. The episode, the ninth in the series, looked back on the climatic and physical upheavals undergone by Earth, before highlighting the mild interglacial climate that allowed the human species to kickstart the neolithic revolution and the first civilizations.
31 activists arrested attempting to stop Arctic oil from docking in Europe
(05/01/2014) Dutch police arrested 31 Greenpeace activists today, who were attempting to block the Russian oil tanker, Mikhail Ulyanov, from delivering the first shipment of offshore Arctic oil to the European market.
Bambi in the 21st Century: roe deer not adapting to climate change
(05/01/2014) Once almost extinct in parts of Europe in the late 17th century, the roe deer (Capreolus capreolus) eventually bounced back, and how: today, it is one of the most widespread deer in Europe. But will its luck dry out in the future? A new study published in PLoSBiology suggests that while roe deer populations are still increasing, it may not be adapting to climate change.
The beef with beef: how 12 strategies could drastically cut agricultural emissions
(04/25/2014) Eating less beef, cutting food waste, and utilizing farm landscapes to sequester carbon are three ways a new report suggests the world could rapidly tackle agricultural emissions. Currently, global agriculture accounts for nearly a fifth of the world's greenhouse gas emissions when agriculturally-linked deforestation is included.
Earth has fourth warmest March on record as forecasters see possible El Nino rising
(04/23/2014) Last March was the fourth warmest on record, according to new data from the National Oceanic and Atmospheric Administration (NOAA). Overall, temperatures were 0.71 degrees Celsius (1.28 degrees Fahrenheit) above the 20th century average during March. Looking at the first three months of 2014, this year is the seventh warmest on record to date.
Behind the scenes of Showtime's blockbuster series on climate change
(04/18/2014) For years climate change activists and environmentalists have been clamoring for a high-profile, high-impact TV series about climate change to make Americans more aware of an issue that will affect billions of people around the globe in coming decades. This week they finally got it when Showtime released the first episode of Years of Living Dangerously, a big-budget TV series featuring a number of Hollywood's biggest stars as reporters and corespondents.
Rainforests on fire: climate change is pushing the Amazon over the edge
(04/18/2014) From 1999-2010, nearly three percent of the Amazon rainforest burned, and climate forecasts indicate dry conditions conducive to fire will only become more commonplace in the future. A new study indicates that rainforests are more vulnerable to fire than previously thought, and it warns the current combination of climate change and deforestation may be pushing Amazon forests past the breaking point.
Climate change solution? UN touts ambitious (but cheap) investment in renewable energy
(04/14/2014) The world is warming rapidly due to greenhouse gas emissions, threatening everything from our food supply to our ecosystems, but the solution may be surprisingly cheap, according to the third and final report from the Intergovernmental Panel on Climate Change (IPCC). The report recommends a rapid and aggressive switch from fossil fuel-based energy to renewables.
Featured video: Showtime releases first episode of major new climate change series online
(04/08/2014) Although Showtime's landmark new climate change series doesn't premiere until Sunday, the network has released an edited version of the first episode of Years of Living Dangerously to the public (see below). The nine-part documentary series is being billed as a "groundbreaking" exploration into the many ways that climate change is already wreaking havoc on the lives of people around the world.
Extinction crisis: rising sea levels will submerge thousands of islands
(04/08/2014) Sea levels are rising at the highest rate in thousands of years, putting at risk low-lying islands around the world. In a new study published in Nature Conservation, researchers found that projected rises in sea level stand to swamp more than 10,000 islands, displacing human communities and wiping many unique species off the face of the earth.
From seals to starfish: polar bears radically shift diet as habitat melts
(04/07/2014) One of the most iconic species of the ongoing climate change drama, polar bears have dropped in numbers as their habitat melts, with previous estimates forecasting a further 30 percent reduction within three generations. However, their situation may not be as dire as it seems.
The incredible shrinking salamander: researchers find another casualty of climate change
(04/04/2014) Climate change is contributing to a slew of global problems, from rising seas to desertification. Now, researchers have added another repercussion: shrinking salamanders. Many amphibian populations around the world are currently experiencing precipitous declines, estimated to be at least 211 times normal extinction rates. Scientists believe these declines are due to a multitude of factors such as habitat loss, agricultural contamination, and the accidental introduction of a killer fungus, among others.
Apocalypse now? Climate change already damaging agriculture, acidifying seas, and worsening extreme weather
(03/31/2014) It's not just melting glaciers and bizarrely-early Springs anymore; climate change is impacting every facet of human civilization from our ability to grow enough crops to our ability to get along with each other, according to a new 2,300-page report from the Intergovernmental Panel on Climate Change (IPCC). The massive report states definitively that climate change is already affecting human societies on every continent.
Deforestation makes Indonesia hotter, reduces quality of life
(03/26/2014) One of the reasons I like living in the tropics is that they are perpetually warm. A pair of shorts and a light shirt will comfortably get you through the day and night in most parts of Indonesia. Still there are the occasional unpleasant extremes. Even the most cold-blooded creature will likely break into a sweat walking for more than a few minutes in the sun filtering through Jakarta’s polluted skies. We consider such heat a normal part of the tropics. But is it really?
The best of the worst: fossil-fuel extractors pave the way for the low-carbon revolution
(03/26/2014) At the end of last year, the world got some good news on the green business front concerning a very unlikely set of participants. A recent market review revealed that Exxon Mobil, Chevron, BP, ConocoPhillips, Royal Dutch Shell, Duke Energy, PG&E Corporation, American Electric Power Company, ConAgra Foods and Walmart, among others, are including shadow carbon prices in their forecasts.
Indigenous people witness climate change in the Congo Rainforest
(03/20/2014) Indigenous communities in the Republic of Congo are observing climate change even though they have no knowledge of the science, according to a unique collaboration between the Rainforest Foundation UK (RFUK) and local communities. The environmental changes witnessed by the locals in the Congo rainforest include increased temperature, less rainfall and alterations to the seasons, much as expected under global climate change.
Controversial Amazon dams may have exacerbated biblical flooding
(03/16/2014) Environmentalists and scientists raised howls of protest when the Santo Antônio and Jirau Dams were proposed for the Western Amazon in Brazil, claiming among other issues that the dams would raise water levels on the Madeira River, potentially leading to catastrophic flooding. It turns out they may have been right: last week a federal Brazilian court ordered a new environmental impact study on the dams given suspicion that they have worsened recent flooding in Brazil and across the border in Bolivia.
Mountain thermostats: scientists discover surprising climate stabilizer that may be key to the longevity of life on Earth
(03/14/2014) What do mountains have to do with climate change? More than you'd expect: new research shows that the weathering rates of mountains caused by vegetation growth plays a major role in controlling global temperatures. Scientists from the University of Oxford and the University of Sheffield have shown how tree roots in certain mountains "acted like a thermostat" for the global climate.
Europe votes for an Arctic Sanctuary
(03/13/2014) Yesterday, the European Parliament passed a resolution supporting the creation of an Arctic Sanctuary covering the vast high Arctic around the North Pole, giving official status to an idea that has been pushed by activists for years. Still, the sanctuary has a long road to go before becoming a reality: as Arctic sea ice rapidly declines due to climate change, there has been rising interest from governments and industries to exploit the once inaccessible wilderness for fish and fossil fuels.
Can penguins cope with climate change? Scientists find different types of ice elicit different responses
(03/13/2014) Human-caused climate change is altering the habitat of Adélie penguins (Pygoscelis adeliae). In an article recently published in PLOS ONE, a team of researchers led by Amélie Lescroël from the Centre d'Ecologie Fonctionnelle et Evolutive (CNRS) in France, found that changes in sea-ice content and newly formed icebergs significantly impacted Adélie penguin communities in the Ross Sea.
From theory to deadly reality: malaria moving upslope due to global warming
(03/06/2014) Malaria is a global scourge: despite centuries of efforts to combat the mosquito-borne disease, it still kills between 660,000 to 1.2 million people a year, according to World Health Organization data from 2010. Astoundingly, experts estimate that around 300 million people are infected with the disease every year or about 4 percent of the world's total population. And these stats may only get worse. For years scientists have vigorously debated whether or not malaria will expand as global warming worsens, but a new study in Science lays down the first hard evidence.
Despite frigid cold in U.S., January was the fourth warmest on record worldwide
(02/27/2014) Worldwide, this January was the fourth warmest since record-keeping began, according to new data released by National Oceanic and Atmospheric Administration (NOAA). While parts of the world, most notably eastern North America and northern Russia, experienced temperatures well-below average, overall the month was a scorcher. In fact, another dataset, from NASA's Goddard Institute for Space Studies (GISS), that uses different methodology, found that January was the third warmest since record keeping began.
Ocean acidifying 10 times faster than anytime in the last 55 million years, putting polar ecosystems at risk
(02/24/2014) An assessment of ocean acidification, presented at the UN Climate Change Conference in Warsaw in November 2013, starkly concluded that acidity is on track to rise 170 percent by the end of this century. As many key species are sensitive to changes in acidity, this would drastically impact ocean ecosystems, with effects especially pronounced in polar regions where the cold waters intensify acidification, and which are home to many organisms that are particularly vulnerable to acidification.
Two kids, one year, from the Amazon to the Arctic: the environmental adventure of a lifetime
(02/19/2014) The Kraft family—Larry, Lauri, Jamie (age 8), and Jason (age 6)—are on the trip of a lifetime, a round-the-world tour with an environmental focus. Currently in India, the family has already made their way through the Amazon, Vietnam, Costa Rica, Australia, and the Galapagos, among other wild places. Still left on their itinerary: the Arctic. But the trip isn't all fun and games, instead the Kraft's are using the year abroad to learn first hand about global environmental issues and solutions.
Alaska roasting: new NASA map shows the Final Frontier in grip of January heatwave
(02/05/2014) Alaska got California weather at the end of January, as displayed by a new map based on data by NASA's Terra satellite's Moderate Resolution Imaging Spectroradiometer (MODIS). The U.S. state experiences one of its warmest winter periods on record during the second half of January, including some temperatures that ran 40 degrees Fahrenheit (22 degrees Celsius) above average. According to the EPA, temperatures in Alaska have risen an average of 3.4 degrees Fahrenheit (1.9 degrees Celsius) in just the last 50 years due to climate change.
20 million people face hunger in Africa's Sahel region
(02/04/2014) The UN and partner humanitarian groups today called on the international community to spend $2 billion to avoid a famine in Africa's Sahel region, which includes nine nations along the southern edge of the Sahara. Although the Sahel is chronically prone to food insecurity, the situation has dramatically worsened as the UN estimates 20 million people are at risk of hunger up from 11 million last year.
Predator appreciation: how saving lions, tigers, and polar bears could rescue ourselves
(01/29/2014) In the new book, In Predatory Light: Lions and Tigers and Polar Bears, authors Elizabeth Marshall Thomas, Sy Montgomery, and John Houston, and photographers Cyril Christo and Marie Wilkinson share with us an impassioned and detailed appeal to appreciate three of the world's biggest predators: lions, tigers, and polar bears. Through lengthy discussions, combining themes from scientific conservation to local community folklore, In Predatory Light takes us step by step deeper into the wild world of these awe-inspiring carnivores and their varied plight as they facedown extinction.
2013 was the seventh hottest year yet
(01/27/2014) Global warming continues apace as 2013 was the seventh warmest year in the past 133 years, according to a new analysis from NASA’s Goddard Institute for Space Studies (GISS). In total, the global temperature in 2013 averaged 14.6 degrees Celsius (58.3 degrees Fahrenheit), or 0.6 degrees Celsius (1.1 degrees Fahrenheit) hotter than the 20th Century average.
Underestimating global warming: gaps in Arctic temperature data lead scientists and public astray
(01/15/2014) No place on Earth is heating up faster than the Arctic, but just how fast has remained an open question due to large gaps in temperature data across the vast region. Now, a recent study in the Quarterly Journal of the Royal Meteorological Society finds that not only is the Arctic warming eight times faster than the rest of the planet, but failure to account for temperature gaps has led global datasets to underestimate the rise of temperatures worldwide.
Carbon emissions rise 2 percent in U.S. due to increase in coal
(01/14/2014) Carbon dioxide emissions rose two percent in the U.S. last year, according to preliminary data from the Energy Information Administration. Emissions rose largely due to increased coal consumption, the first such rise in U.S. emissions since 2010. Still, the annual emissions remain well below the peak hit in 2007 when emissions hit 6 billion tons.
