(01/15/2013) 2012 was the ninth warmest year since annual record-keeping began in 1880 say NASA scientists who cited rising greenhouse gas emissions as the chief culprit.
Soot is second biggest man-made contributor to global warming
(01/15/2013) Soot is the second largest man-made contributor to global warming, according to a comprehensive new study published in the Journal of Geophysical Research: Atmospheres.
Climate change already pummeling U.S. according to government report
(01/14/2013) Climate change is on the march across the U.S. according to a new draft report written by U.S. government scientists with input from 240 experts. It documents increasing and worsening extreme weather, rising sea levels, and ocean acidification among other impacts. Released Friday for public review, the report will be officially launched later this year or early in 2014.
A second look at 'Fewer, Richer, Greener: The End of the Population Explosion and the Future for Investors'
(01/14/2013) Fewer, Richer, Greener: The End of the Population Explosion and the Future for Investors (November/December 2012, Vol. 68, No. 6: 20–37), by Mr. Laurence B. Siegel provides us with a commentary of population explosion and green investment opportunities over the long-run.
Paradigm shift needed to avert global environmental collapse, according to author of new book The Blueprint: Averting Global Collapse
(01/10/2013) Global strategist, trained educator, and international lecturer Daniel Rirdan set out to create a plan addressing the future of our planet. His book The Blueprint: Averting Global Collapse, published this year, does just that. "It has been a sixty hour a week routine," Rirdan told mongabay.com in a recent interview. "Basically, I would wake up with the burden of the world on my shoulders and go to sleep with it. It went on like this for eighteen months." It becomes apparent when reading The Blueprint that it was indeed a monumental undertaking.
Australia reels from record heatwave, fires
(01/09/2013) Yesterday Australia recorded its highest average temperature yet: 40.33 degrees Celsius (104.59 Fahrenheit). The nation has been sweltering under an unprecedented summer heatwave that has spawned wildfires across the nation, including on the island of Tasmania where over 100 houses were engulfed over the weekend. Temperatures are finally falling slightly today, providing a short reprieve before they are expected to rise again this weekend.
2012 was America's warmest year on record
(01/08/2013) 2012 was the warmest year on record for the contiguous U.S. according to the National Oceanic and Atmospheric Administration (NOAA).
Mountain pine beetle threatening high-altitude, endangered trees
(01/02/2013) In the western U.S., few trees generally grow in higher altitudes than the whitebark pine (Pinus albicaulis). Providing shelter and food for bears, squirrels and birds, the whitebark pine ecosystems also help regulate water flow from snowmelt. But, according to a new study in the Proceedings of the National Academy of Sciences (PNAS), climate change has produced a novel threat for these high-altitude forests : mountain pine beetles (Dendroctonus ponderosae).
Top 10 Environmental Stories of 2012
(12/18/2012) Below is a quick review of some of the biggest environmental stories of 2012. The 'top stories' are listed in no particular order. Climate change, overpopulation, consumption, and ecological destruction is pushing planet Earth toward a tipping point according to a major study in Nature released over the summer. This could result in a new 'planetary state' that would be far harsher and bleaker than the current one (beginning around 12,000 years ago), which saw the rise and success of human society.
99.999% chance 2012 will be hottest year on record for continental U.S
(12/13/2012) 2012 will almost certainly be the hottest year on record across the 48 contiguous United States, says a new analysis published by Climate Central.
Climate Summit in Doha characterized by lack of ambition
(12/09/2012) Ahead of the 18th United Nations Framework Convention on Climate Change (UNFCCC) in Doha, Qatar a variety of reports warned that the world was running out of time to avoid dangerous climate change, and that there was a widening gap between what nations have pledged to do and what the science demanded. A landmark report by the World Bank painted an almost apocalyptic picture of a world in which global temperatures have risen 4 degrees Celsius above pre-industrial levels, including unprecedented heatwaves and droughts, rising sea levels, global agriculture crises, and a stunning loss of species. In addition, scientific studies released near the two week conference found that sea levels were rising 60 percent faster than predicted, forests around the world were imperiled by increasing drought, marine snails were dissolving in the Southern Ocean due to ocean acidification, and ice melt in Greenland and Antarctica was on the rise.
Illegal logging, mining worsened impact of Philippines' killer typhoon
(12/06/2012) According to Filipino officials, rampant illegal logging and mining were likely a part of the cause for the high casualty count from Category 5 Typhoon Bopha (Pablo), especially in the Compostela Valley where government officials had warned people to stop the illegal activities. So far, 370 people have been found dead on the island of Mindanao with another 400 missing. Waters rose so high even emergency shelters were inundated.
Wealthy nations' fossil fuel subsidies dwarf climate financing
(12/05/2012) A new analysis finds that 21 wealthy countries spent five-times more on subsidizing fossil fuels in 2011 than they have on providing funds for poor nations to cut greenhouse gas emissions and adapt to the impacts of climate change. The analysis, by Oil Change International, comes in the midst of the current UN Climate Summit held in Doha, Qatar; progress at the talks has been stymied due to the gulf between poor and rich nations, including on the issue of climate financing.
Animals dissolving due to carbon emissions
(12/03/2012) Marine snails, also known as sea butterflies, are dissolving in the Southern Seas due to anthropogenic carbon emissions, according to a new study in Nature GeoScience. Scientists have discovered that the snail's shells are being corroded away as pH levels in the ocean drop due to carbon emissions, a phenomenon known as ocean acidification. The snails in question, Limacina helicina antarctica, play a vital role in the food chain, as prey for plankton, fish, birds, and even whales.
'No-one is listening to the entire scientific community': global carbon emissions set to hit new high
(12/03/2012) Global carbon dioxide (CO2) emissions from industrial sources are set to hit a new record high this year according to a new analysis by Global Carbon Project. The analysis in Nature Climate Changes predicts that CO2 emissions will rise another 2.6 percent, hitting 35.6 billion tonnes. The scientists warn that such steep climbs in global emissions year-after-year means that the door is rapidly closing on a global agreement to keep temperatures from rising 2 degree Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.
Science and Public Reason - book review
(12/03/2012) Professor Sheila Jasanoff’s superb treatise Science and Public Reason, part of Earthscan's, is a wonderful book describing, through a collection of her essays and articles from the past 25-years, the rise of the field of Science and Technology Studies. The book could not have arrived soon enough, as we now globally face the triple threat of 1) massive biodiversity loss, 2) nutrient cycling disruption (greenhouse gases, Montreal Protocol gases, nitrogen fertilizer caused eutrophication, etc.), and 3) water quality degradation (saltwater intrusion, depleted aquifers, lack of clean drinking water, etc.).
Greenland and Antarctica ice melt accelerating, pushing sea levels higher
(12/03/2012) A massive team of scientists have used multiple methods to provide the best assessment yet of ice loss at the world's poles, including Greenland and a number of Antarctic ice sheets. Their findings—that all major ice sheets are shrinking but one; that ice loss is speeding up; and that this is contributing to the rise in sea levels—add more evidence to the real-time impacts from global climate change. Melting ice sheets at the poles have raised sea levels 11.1 millimeters, or about 20 percent of observed sea level rise, in the past twenty years, according to the landmark study in Science.
Reduction in snow threatens Arctic seals
(11/28/2012) Arctic snowfall accumulation plays a critical role in ringed seal breeding, but may be at risk due to climate change, according to a new study in Geophysical Research Letters. Sea ice, which is disappearing at an alarming rate, provides a crucial platform for the deep snow seals need to reproduce. Ringed seals (Phoca hispida) require snow depths of at least 20 centimeters (8 inches): deep enough to form drifts that seals use as birth chambers.
Watery world: sea level rising 60 percent faster than predicted
(11/28/2012) Sea levels are rising 60 percent faster than Intergovernmental Panel on Climate Change (IPCC) has estimated, according to a new study in the open access Environmental Research Letters. In addition to imperiling coastal regions and islands, global sea level rise is worsening the damage inflicted by extreme weather such as Hurricane Sandy, which recently brought catastrophic flooding to the New Jersey coast and New York City.
Organic farming keeps carbon out of the atmosphere
(11/28/2012) With the worst effects of climate change, we are seeing how pollution hurts both human health and the environment but there is good news: a new study shows that organic farming stores more greenhouse gases in the soil than non-organic farming. By switching to organic methods, many farmers across the globe may be helping to solve the climate crisis at the same time as they improve soil quality and avoid the use of pesticides.
Hopes pinned on Obama again as Doha Climate Summit opens
(11/26/2012) A number of observers have expressed hope that the Obama Administration, fresh from a re-election victory in the U.S., will take a more active and ambitious role at this year's UN Climate Summit, held in Doha, Qatar. The summit opens amid fresh—and increasingly dire—warnings over climate change from the World Bank, the International Energy Agency, and the UN itself.
Unique program to leave oil beneath Amazonian paradise raises $300 million
(11/26/2012) The Yasuni-ITT Initiative has been called many things: controversial, ecological blackmail, revolutionary, pioneering, and the best chance to keep oil companies out of Ecuador's Yasuni National Park. But now, after a number of ups and downs, the program is beginning to make good: the Yasuni-ITT Initiative has raised $300 million, according to the Guardian, or 8 percent of the total amount needed to fully fund the idea.
China and India plan 818 new coal plants
(11/26/2012) Even as the clamor to reduce greenhouse gas emissions reaches a new high—echoed recently by such staid institutions as the World Bank and the International Energy Agency (IEA)—a new analysis by the World Resources Institute (WRI) finds that 818 new coal-fired plants are under proposal in China and India. In all 1,199 new coal-fired plants are currently planned worldwide, according to the report, totaling 1.4 million megawatts of energy.
As Doha Climate Summit kicks off, more ambitious cuts to greenhouse gas emissions needed
(11/26/2012) As the 18th meeting of the UN Framework Convention on Climate Change (UNFCCC) kicks off this morning in oil and gas rich Qatar, the world body warns that much more ambitious greenhouse gas cuts are needed to keep catastrophic climate change at bay. A new report by the UN Environment Program (UNEP) and the European Climate Foundation finds that even if all current emissions pledges are kept, the world will still spew 8 billion tonnes of CO2 equivalent above what is needed by 2020, putting the globe on a fast-track to dangerous climate change.
Forests worldwide near tipping-point from drought
(11/23/2012) Forests worldwide are at 'equally high risk' to die-off from drought conditions, warns a new study published this week in the journal Nature. The study, conducted by an international team of scientists, assessed the specific physiological effects of drought on 226 tree species at 81 sites in different biomes around the world. It found that 70 percent of the species sampled are particularly vulnerable to reduction in water availability. With drought conditions increasing around the globe due to climate change and deforestation, the research suggests large swathes of the world's forests — and the services they afford — may be approaching a tipping point.
Hotter and hotter: concentrations of greenhouse gases hit another new record
(11/20/2012) As expected, greenhouse gas concentrations in the Earth's atmosphere hit another record last year, according to a new UN World Meteorological Organization (WMO). The increasing concentrations of greenhouse gases means that radiative forcing—changes in the atmosphere's energy balance that leads to warming—has jumped 30 percent in the last twenty years.
World Bank: 4 degrees Celsius warming would be miserable
(11/20/2012) A new report by the World Bank paints a bleak picture of life on Earth in 80 years: global temperatures have risen by 4 degrees Celsius spurring rapidly rising sea levels and devastating droughts. Global agriculture is under constant threat; economies have been hampered; coastal cities are repeatedly flooded; coral reefs are dissolving from ocean acidification; and species worldwide are vanishing. This, according to the World Bank, is where we are headed even if all of the world's nations meet their pledges on cutting greenhouse gas emissions. However, the report also notes that with swift, aggressive action it's still possible to ensure that global temperatures don't rise above 4 degrees Celsius.
Climate activists march on White House again to oppose Keystone XL pipeline
(11/19/2012) Yesterday, climate activists marched around the White House in opposition against the Keystone XL pipeline, which if built will carry tar sands from Canada to the Gulf of Mexico and an international market. The protest, which included over 3,000 people according to organizing groups, is an opening salvo in activists' battle to convince the Obama Administration to turn down the pipeline for good.
Mr. Jeremy Grantham and Extreme Weather and The Financial Markets: Opportunities in Commodities and Futures
(11/19/2012) Mr. Jeremy Grantham, co-chair of the Grantham Foundation for the Protection of the Environment and co-founder and chief investment strategist at GMO, published an online column November 14, 2012 in Nature asking scientists to speak out forcefully, publicly and directly on strategies to mitigate climate change. Mr. Grantham’s column titled Be persuasive. Be brave. Be arrested (if necessary) is a clear clarion call for action. As a fellow natural resources scientist, I agree with Mr. Grantham’s intent.
Climate change threatens population of Earth’s largest sea turtle
(11/19/2012) A drier, hotter climate in Central America could wipe out the population of leatherback sea turtles from the eastern Pacific Ocean by the year 2100, according to a grim projection published on July 1 in Nature Climate Change. Already critically endangered from fisheries by-catch and historic egg poaching, leatherbacks can hardly accommodate another human-related threat. Yet scientists still hold out hope for interventions that could save the turtles.
Good Derivatives: A Story of Financial and Environmental Innovation – Book Review
(11/18/2012) In Good Derivatives: A Story of Financial and Environmental Innovation, Richard Sandor, PhD has written a rich compelling first-person narrative of the development of financial futures and environmental markets over the past 40 years. With personal stories describing both failures and successes, Dr. Richard Sandor engages us with details that expand our knowledge of the capacities and limitations capital markets present to us in our efforts to finance climate change mitigation and natural resources conservation.
Asian cities face high disaster risk with 650,000 killed in 2000's
(11/16/2012) Asia's cities are increasing vulnerable to natural disasters due to climate change, urban expansion, and poor planning, warns a report published this week by the Asian Development Bank. Disasters risk undermining recent economic gains in the region.
Obama criticized for lack of urgency on climate change
(11/15/2012) Following the devastation wrought by Hurricane Sandy—which many scientists say was likely worsened by climate change—and a long silence on the issue of global warming during the Presidential campaign, environmentalists yesterday were disappointed when re-elected President Barack Obama seemingly put action on climate change on the back burner.
Bats face new perils from climate change
(11/15/2012) Global climate change could devastate bat populations around the world, threatening to tear yet another thread from the tapestry of biodiversity should current temperature trends persist, according to a new study. "Bats were the focus for this study because they are relatively understudied but due to their sensitivity to environmental stress, they are excellent indicators of climate change," Hayley Ann Sherwin, co-author of the paper published in Mammal Review, with the Queen University in Belfast, told mongabay.com.
Obama breaks climate silence at press conference
(11/14/2012) At a news conference today, a question by New York Times reporter Mark Landler pushed President Obama to speak at some length about climate change. In his answer, Obama re-iterated his acceptance of climate science and discussed how progress on tackling climate change might proceed in his second term, though he also noted that he wouldn't put action on the climate ahead of the economy. President Obama made a small reference to climate change in his victory speech following his historic re-election last Tuesday, but his answer today was the most the president has talked about the issue at any length since at least Hurricane Sandy.
Gaining from rain: precipitation is an indicator of tropical forest biodiversity
(11/12/2012) Policymakers seeking to conserve forests in southern India should focus on those receiving the highest levels of rainfall, according to new research. Scientists from the Center for International Forestry Research (CIFOR) found rainfall to be the most important environmental determinant of species richness in the Anamalai region of the southern Western Ghats.
Day after Obama re-elected, group plans massive march over Keystone Pipeline and climate change
(11/07/2012) Hours after President Obama's historic re-election, climate group 350.org announced a massive rally to apply pressure on the administration to reject the Keystone Pipeline, which would bring tar sands from Alberta to an international market. In 2011 the group and its partners carried out massive civil disobedience action, resulting in over 1,000 arrests, and a rally 12,000-strong that literally encircled the White House. The pressure, which was also brought to Obama campaign offices around the country, helped spur the Obama Administration to suspend the pipeline.
Threatened Galapagos coral may predict the future of reefs worldwide
(11/07/2012) The Galapagos Islands have been famous for a century and a half, but even Charles Darwin thought the archipelago’s list of living wonders didn’t include coral reefs. It took until the 1970s before scientists realized the islands did in fact have coral, but in 1983, the year the first major report on Galapagos reef formation was published, they were almost obliterated by El Niño. This summer, a major coral survey found that some of the islands’ coral communities are showing promising signs of recovery. Their struggle to survive may tell us what is in store for the rest of the world, where almost three-quarters of corals are predicted to suffer long-term damage by 2030.
It's not just Sandy: U.S. hit by record droughts, fires, and heatwaves in 2012
(11/05/2012) As the devastation wrought by Hurricane Sandy—killing over 100 people and producing upwards of $50 billion in damage along the U.S. East Coast—has reignited a long-dormant conversation on climate change in the media, it's important to note that this is not the only weird and wild weather the U.S. has seen this year. In fact, 2012 has been a year of record-breaking weather across the U.S.: the worst drought in decades, unprecedented heatwaves, and monster forest fires. While climatologists have long stated that it is not yet possible to blame a single extreme weather event on climate change, research is showing that rising temperatures are very likely increasing the chances of extreme weather events and worsening them when they occur.
Micro-hydro and decentralized green energy goals set in Borneo
(11/04/2012) The first ever meeting of the Southeast Asia Renewable Energy People's Assembly (SEAREPA) ended with agreement on 12 future projects, including developing community micro-hydro power and pushing for new policies on decentralized renewable energy in the region. Held in Malaysian state of Sabah on the island, the meeting brought together 130 people from some 80 different groups.
From 'fertilizer to fork': food accounts for a quarter of the world's greenhouse gas emissions
(11/01/2012) Growing, transporting, refrigerating, and wasting food accounts for somewhere between 19-29 percent of the world's greenhouse gas emissions in 2008, according to a new analysis by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). In hard numbers that's between 9.8 and 16.9 billion tonnes of carbon dioxide, more than double the fossil fuel emissions of China in the same year. Over 80 percent of food emissions came from production (i.e. agriculture) which includes deforestation and land use change.
Above the ocean: saving the world's most threatened birds
(11/01/2012) A life on the ocean is a perilous one for any bird. They must expend energy staying aloft for thousands of miles and learn to be marathon swimmers; they must seek food beneath treacherous waves and brave the world's most extreme climates; they must navigate the perils both of an unforgiving sea and far-flung islands. Yet seabirds, which includes 346 global species that depend on marine ecosystems, have evolved numerous strategies and complex life histories to deal with the challenges of the sea successfully, and they have been doing so since the dinosaur’s last stand. Today, despite such a track record, no other bird family is more threatened; yet it's not the wild, unpredictable sea that endangers them, but pervasive human impacts.
After defeating coal plant, Borneo hosts renewable energy meeting
(10/31/2012) Last year, a coalition of environmentalists and locals won a David-versus-Goliath battle against a massive coal plant in the Malaysian state of Sabah on Borneo. After facing a protracted campaign—including expert analysis of green energy options for Sabah—the state government announced it was scuttling plans to build the coal plant on a beach overlooking the Coral Triangle. Now, victorious grassroots campaigners are hosting the inaugural meeting of the Southeast Asia Renewable Energy People’s Assembly (SEAREPA), bringing 80 organizations together to discuss green energy options across southeast Asia.
Hours before Hurricane Sandy hit, activists protested climate inaction in Times Square
(10/30/2012) On Sunday, as Hurricane Sandy roared towards the coast of the Eastern U.S., activists took to the streets in New York City to highlight the issue of climate change. Activists organized by 350.org unfurled a huge parachute in Times Square with the words, "End Climate Silence," a message meant to call attention to the fact that there has been almost zero mention of climate change during the presidential campaign, including not a single reference to the issue in the four presidential debates.
How climate change may be worsening Hurricane Sandy
(10/29/2012) While scientists are still debating some fundamental questions regarding hurricanes and climate change (such as: will climate change cause more or less hurricanes?), there's no debating that a monster hurricane is now imperiling the U.S. East Coast. A few connections between a warmer world and Hurricane Sandy can certainly be made, however: rising sea levels are likely to worsen storm surges; warmer waters bring more rain to increase flooding; and hotter temperatures may allow the hurricane to push both seasonal and geographic boundaries.
Lack of climate change in presidential debates part of larger trend
(10/23/2012) The final presidential debate between President Barack Obama and Governor Mitt Romney, focusing on foreign policy, ended like all the others: without a mention of climate change or its likely impacts on Americans, from rising sea levels to worsening extreme weather to the threat of instability abroad. While environmental groups have kicked-off a campaign to target this "climate silence," the lack of discussion on climate change is a part of a larger trend in the U.S. where media coverage of the issue has declined even as scientists argue that impacts are increasing.
Will we need to pull carbon out of the atmosphere to save ourselves?
(10/17/2012) This year saw the Arctic sea ice extent fall to a new and shocking low, while the U.S. experienced it warmest month ever on record (July), beating even Dust Bowl temperatures. Meanwhile, a flood of new research has convincingly connected a rise in extreme weather events, especially droughts and heatwaves, to global climate change, and a recent report by the DARA Group and Climate Vulnerability Forum finds that climate change contributes to around 400,000 deaths a year and costs the world 1.6 percent of its GDP, or $1.2 trillion. All this and global temperatures have only risen about 0.8 degrees Celsius (1.44 degrees Fahrenheit) since the early Twentieth Century. Scientists predict that temperatures could rise between 1.1 degrees Celsius (2 degrees Fahrenheit) to a staggering 6.4 degrees Celsius (11.5 degrees Fahrenheit) by the end of the century.
One in eight people suffer from malnutrition worldwide
(10/16/2012) In a world where technology has advanced to a point where I can instantly have a face-to-face conversation via online video with a friend in Tokyo, nearly 870 million people, or one in eight, still suffer from malnutrition, according to a new UN report. While worldwide hunger declined from 1990 to 2007, progress was slowed by the global economic crisis. Over the last few years, numerous and record-breaking extreme weather events have also taken tolls on food production. Currently, food prices hover just below crisis levels.
September tied for world's warmest on record
(10/16/2012) September 2012 tied with 2005 for the warmest on record around the globe, according to new data released by the National Oceanic and Atmospheric Administration (NOAA). The average land and ocean temperature was 16.27 degrees Celsius (61.31 degrees Fahrenheit) for this September, 0.67 degrees Celsius (1.21 degrees Fahrenheit) above the 20th Century average for the month. Shockingly, this is the 331st month in a row that has been above the 20th Century average.
Norway to double carbon tax on oil industry for climate change programs
(10/15/2012) Beginning next year, Norway will nearly double the carbon tax on its domestic oil industry to help set up a $1 billion climate change fund for programs in developing nations among other green projects. The Scandinavian nation is the world's 13 largest oil producer and third biggest oil exporter, yet has been one of the most active champions of funding climate change projects.
