Climate and The Oceans - Princeton Primers in Climate: A Book Review
(01/25/2012) Climate and The Oceans by Dr. Geoffrey K. Vallis provides a coherent, well-articulated primer on how the oceans impact the Earth's climate. This easy-to-read illustrated book, filled with both data and accessible mathematical equations demonstrating the impact of the oceans on the Earth's climate, offers practitioners and stakeholders' state-of-the-art scientific analysis of how the oceans and climate interact that is both user friendly to the non-expert yet scientifically rigorous enough as bridge material for graduate students as they grapple with the compelling field of climate science and oceanography.
Acid oceans: in some regions acidification a 'hundred times greater' than natural variation
(01/24/2012) Emissions of carbon over the last two centuries have raised the acidity of the oceans to the highest levels in 21,000 years and likely beyond, according to a new study in Nature Climate Change. The change threatens a number of marine species, including coral reefs and molluscs.
The Cryosphere-Princeton primers in climate: A Book Review
(01/23/2012) The Cryosphere by Dr. Shawn J. Marshall, Canada Research Chair in Climate Change, University of Calgary, is an excellent book because it summarizes leading scientific research into easily accessible chapters each one on a different component of the cryosphere. The cryosphere, which incorporates the Earth's snow and ice mass including seasonal snow, permafrost (both land-based permafrost and below water permafrost), river and lake ice, sea ice, glaciers, ice sheets, and ice shelves, is intrinsically related to global climate change. Hence, understanding how the cryosphere interacts with and is at risk because of climate change and its greenhouse gases is fundamental to developing effective policy mechanisms that mitigate climate change.
NASA: 2011 ninth warmest year yet
(01/23/2012) Despite being a strong La Niña year, which tends to be cooler than the average year, 2011 was the ninth warmest year on record and the warmest La Niña yet, according to a global temperature analysis by NASA. To date, nine of the world's ten warmest years have occurred since 2000 according to data going back to 1880.
Hugh Powell: birds lend invaluable insight into ecosystems
(01/23/2012) Hugh Powell is science editor at the Cornell Lab of Ornithology as well as a contributor to Woods Hole Oceanographic Institution's Oceanus and other publications. He's traveled extensively while writing, including stints in Antarctica for WHOI's Live from the Poles. Before finding his niche as a science writer, Hugh studied the interconnections between black-backed woodpeckers, insects, and forest fires in Montana. He currently resides in Ithaca, New York.
Deforestation, climate change threaten the ecological resilience of the Amazon rainforest
(01/19/2012) The combination of deforestation, forest degradation, and the effects of climate change are weakening the resilience of the Amazon rainforest ecosystem, potentially leading to loss of carbon storage and changes in rainfall patterns and river discharge, finds a comprehensive review published in the journal Nature.
Obama rejects Keystone pipeline, but leaves door open for tar sands
(01/18/2012) The Obama administration today announced it is scrapping TransCanada's Keystone pipeline after Republicans forced a 60-day deadline on the issue in a Congressional rider. The State Department advised against the pipeline arguing that the deadline did not give the department enough time to determine if the pipeline "served the national interest." The cancellation of the pipeline is a victory for environmental and social activists who fought the project for months, but Republicans are blasting the administration.
Delayed response to Somalia famine cost thousands of lives
(01/18/2012) A hesitant response by the international community likely led to thousands of unnecessary deaths in last year's famine in East Africa finds a new report released by Oxfam and Save the Children. The report, entitled A Dangerous Delay, says that early warning systems worked in informing the international community about the likelihood of a dire food crisis in East Africa, however a "culture of risk aversion" led to months-long delays. By the time aid arrived it was already too late for many. The British government has estimated somewhere between 50,000 and 100,000 people perished in the famine, half of whom were likely children under five.
One company behind U.S.'s top three biggest greenhouse gas emitters
(01/16/2012) The Atlanta-based Southern company owns the top three biggest sources of greenhouse gas emissions in the U.S. according to recent data released by the Environmental Protection Agency (EPA). Three of Southern's coal-fired plants—two in Georgia and one in Alabama—account for around 64.74 million metric tons of total greenhouse gas emissions, higher than all of Finland's carbon emission in 2008.
Climate change may make lizards smarter, if they don't go extinct first
(01/12/2012) A new study in Biology Letters has found that warmer temperatures may make lizards smarter, even as past studies have linked a global decline in lizards to climate change.
Targeting methane, black carbon could buy world a little time on climate change
(01/12/2012) A new study in Science argues that reducing methane and black carbon emissions would bring global health, agriculture, and climate benefits. While such reductions would not replace the need to reduce CO2 emissions, they could have the result of lowering global temperature by 0.5 degrees Celsius (0.9 degree Fahrenheit) by mid-century, as well as having the added benefits of saving lives and boosting agricultural yields. In addition, the authors contend that dealing with black carbon and methane now would be inexpensive and politically feasible.
Seals, birds, and alpine plants suffer under climate change
(01/11/2012) The number of species identified by scientists as vulnerable to climate change continues to rise along with the Earth's temperature. Recent studies have found that a warmer world is leading to premature deaths of harp seal pups (Pagophilus groenlandicus) in the Arctic, a decline of some duck species in Canada, shrinking alpine meadows in Europe, and indirect pressure on mountain songbirds and plants in the U.S. Scientists have long known that climate change will upend ecosystems worldwide, creating climate winners and losers, and likely leading to waves of extinction. While the impacts of climate change on polar bears and coral reefs have been well-documented, every year scientists add new species to the list of those already threatened by anthropogenic climate change.
How lemurs fight climate change
(01/09/2012) Kara Moses may have never become a biologist if not for a coin toss. The coin, which came up heads and decided Moses' direction in college, has led her on a sinuous path from studying lemurs in captivity to environmental writing, and back to lemurs, only this time tracking them in their natural habitat. Her recent research on ruffed lemurs is attracting attention for documenting the seed dispersal capabilities of Critically Endangered ruffed lemurs as well as theorizing connections between Madagascar's lemurs and the carbon storage capacity of its forests. Focusing on the black-and-white ruffed lemur's (Varecia variegata) ecological role as a seed disperser—animals that play a major role in spreading a plant's seeds far-and-wide—Moses suggests that not only do the lemurs disperse key tree species, but they could be instrumental in dispersing big species that store large amounts of carbon.
Climate change media coverage drops 20 percent in 2011
(01/05/2012) Global media reporting on climate change issues was down again last year, according to a new analysis from The Daily Climate. The news organization counted around 19,000 stories on climate issues during the year written by 7,140 journalists, falling 20 percent from 2010 levels.
Ecuador makes $116 million to not drill for oil in Amazon
(01/02/2012) A possibly ground-breaking idea has been kept on life support after Ecuador revealed its Yasuni-ITT Initiative had raked in $116 million before the end of the year, breaking the $100 million mark that Ecuador said it needed to keep the program alive. Ecuador is proposing to not drill for an estimated 850 million barrels of oil in the Ishpingo-Tambococha-Tiputinin (ITT) blocs of Yasuni National Park if the international community pledges $3.6 billion to a United Nations Development Fund (UNDF), or about half of what the oil is currently worth. The Yasuni-ITT Initiative would preserve arguably the most biodiverse region on Earth from oil exploitation, safeguard indigenous populations, and keep an estimated 410 million tons of CO2 out of the atmosphere. However, the initiative is not without its detractors, some arguing the program is little more than blackmail; meanwhile proponents say it could prove an effective way to combat climate change, deforestation, and mass extinction.
The year in review for rainforests
(12/28/2011) 2011 was designated as "Year of the Forests" by the United Nations. While there was relatively little progress on intergovernmental forest protection programs during the year, a lot happened elsewhere. Below is a look at some of the biggest tropical forest-related news stories for 2011. We at mongabay readily acknowledge there were a number of important temperate and boreal forest developments, including Britain's decision not to privatize its forests and the severe drought in Texas, but this article will cover only tropical forest news.
Top 10 Environmental Stories of 2011
(12/22/2011) Many of 2011's most dramatic stories on environmental issues came from people taking to the streets. With governments and corporations slow to tackle massive environmental problems, people have begun to assert themselves. Victories were seen on four continents: in Bolivia a draconian response to protestors embarrassed the government, causing them to drop plans to build a road through Tipnis, an indigenous Amazonian reserve; in Myanmar, a nation not known for bowing to public demands, large protests pushed the government to cancel a massive Chinese hydroelectric project; in Borneo a three-year struggle to stop the construction of a coal plant on the coast of the Coral Triangle ended in victory for activists; in Britain plans to privatize forests created such a public outcry that the government not only pulled back but also apologized; and in the U.S. civil disobedience and massive marches pressured the Obama Administration to delay a decision on the controversial Keystone XL pipeline, which would bring tar sands from Canada to a global market.
Earth systems disruption: Does 2011 indicate the "new normal" of climate chaos and conflict?
(12/21/2011) The year 2011 has presented the world with a shocking increase in irregular weather and disasters linked to climate change. Just as the 2007 "big melt" of summer arctic sea ice sent scientists and environmentalists scrambling to re-evaluate the severity of climate change, so have recent events forced major revisions and updates in climate science.
Texas loses half a billion trees to epic drought
(12/21/2011) A punishing drought in Texas has not only damaged crops, killed cattle, and led to widespread fires, but has also killed off a significant portion of the state's trees: between 100 and 500 million trees have perished to drought stress according to preliminary analysis. The estimate does not include tree mortality caused by fires. The drought has been linked to La Niña conditions, which causes drying in the Southern U.S., and has likely been exacerbated by global climate change.
Philippines disaster may have been worsened by climate change, deforestation
(12/20/2011) As the Philippines begins to bury more than a 1,000 disaster victims in mass graves, Philippine President Benigno Aquino has ordered an investigation into last weekend's flash flood and landslide, including looking at the role of illegal logging. Officials have pointed to both climate change and vast deforestation as likely exacerbating the disaster.
Droughts could push parts of Africa back into famine
(12/19/2011) Drought and erratic rains could lead to further food scarcities in Africa warns the United Nations World Food Program (WFP). The WFP singles out South Sudan, the world's newest nation, and Niger as nations of particular concern. Earlier this year famine killed scores of people, including an estimated 30,000 children, in Somalia.
Facebook pledges to go green...someday soon
(12/15/2011) After a massive campaign by Greenpeace to get everyone's favorite social media site to quit coal energy, Facebook has announced a new energy policy and a partnership with Greenpeace. The policy includes a goal "to power all of our operations with clean and renewable energy," however does not go so far as to state it is dropping coal at this time or give a timeline as to when it may do so. Still, Greenpeace is calling the new policy by Facebook a victory.
Photos: 208 species discovered in endangered Mekong region in 2010
(12/14/2011) Last year researchers scoured forests, rivers, wetlands, and islands in the vanishing ecosystems of the Mekong Delta to uncover an astounding 208 new species over a twelve month period. A new report by the World Wide Fund for Nature (WWF) highlights a number of the new species—from a new snub-nosed monkey to five new meat-eating pitcher plants to a an all-female, cloning lizard—while warning that many of them may soon be gone as the Mekong Delta suffers widespread deforestation, over-hunting and poaching, massive development projects, the destruction of mangroves, pollution, climate change, and a growing population.
Carbon Coalitions: Business, Climate Politics, and the Rise of Emissions Trading: Book Review
(12/13/2011) Jonas Meckling, PhD., writes the first critical analysis demonstrating how various types of not-for-profit, governmental and for-profit coalitions over the past couple of decades have led to the development of the global carbon market, valued in 2010 at US$ 142 billion.
Harsh words for Canada after it abandons Kyoto Protocol
(12/13/2011) Less than two days after signing on to a "road map" agreement at the UN Climate Summit in Durban, South Africa, Canada has announced it is formally withdrawing from the Kyoto Protocol after failing to meet its emissions pledges. Although not surprising, reaction from other nations and environmental groups was not only swift, but harsh.
Mixed reactions to the Durban agreement
(12/12/2011) Early Sunday morning over 190 of the world's countries signed on to a new climate agreement at the 17th UN Framework Convention on Climate Change (UNFCCC) in Durban, South Africa. The summit was supposed to end on Friday, but marathon negotiations pushed government officials to burn the midnight oil for about 36 extra hours. The final agreement was better than many expected out of the two week summit, but still very far from what science says is necessary to ensure the world does not suffer catastrophic climate change.
The Atlas of Climate Change: Mapping the World’s Greatest Challenge – a book review
(12/12/2011) The Atlas of Climate Change: Mapping the World’s Greatest Challenge presents in clear and concise visual form the impacts and effects, solutions and mitigation actions surrounding climate change - which is our greatest global challenge.
Evidence mounts that Maya did themselves in through deforestation
(12/08/2011) Researchers have garnered further evidence for a smoking gun behind the fall of the great Maya civilization: deforestation. At the American Geophysical Union (AGU) conference, climatologist Ben Cook presented recent research showing how the destruction of rainforests by the Mayan ultimately led to declines in precipitation and possibly civilization-rocking droughts. While the idea that the Maya may have committed ecological-suicide through deforestation has been widely discussed, including in Jared Diamond's popular book Collapse, Cook's findings add greater weight to the theory.
Yasuni ITT: the virtues and vices of environmental innovation
(12/07/2011) As the 17th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) is taking place in Durban, Ecuador has embarked on the development of a project presented as highly innovative. This project targets Yasuni National Park, which has been protected since 1979. Yasuni is home to several indigenous peoples and is a biodiversity hotspot. But it so happens that the park also sits atop a vast oil field of 846 million barrels, representing about 20 percent of the country’s oil reserves. The acronym Yasuni ITT stands for Ishpingo-Tambococha-Tiputinin, which are the names of three potential zones for oil extraction.
Discovery Channel backtracks, promises to air climate change episode of new Frozen Planet series
(12/07/2011) Discovery Channel has announced that it will, in fact, air the last episode of the new series Frozen Planet, which focuses solely on the impact of climate change at the world's poles. By the creators of universally-acclaimed Planet Earth, the full series explores the wildlife and environs of the Arctic and Antarctic, but the Discovery Channel came under fire after it announced it would not air the last episode, called "On Thin Ice", which deals specifically with climate change. A petition on Change.org garnered 75,000 signatures calling on the Discovery Channel to air the full series, before the network caved and announced it would do so.
Current emission pledges will raise temperature 3.5 degrees Celsius
(12/06/2011) New research announced at the 17th UN Climate Summit in Durban, South Africa finds that under current pledges for reducing emissions the global temperature will rise by 3.5 degrees Celsius (6.3 degrees Fahrenheit) from historic levels, reports the AFP. This is nearly double world nations' pledge to keep warming below 2 degrees Celsius (3.6 degrees Fahrenheit). The report flies in the face of recent arguments by the U.S. and others at Durban that current pledges are adequate through 2020.
At least 74 percent of current warming caused by us
(12/05/2011) A new methodology to tease out how much current climate change is linked to human activities has added to the consensus that behind global warming is us. The study, published in Nature Geoscience found that humans have caused at least three-quarters (74 percent) of current warming, while also determining that warming has actually been slowed down by atmospheric aerosols, including some pollutants, which reflect sunlight back into space.
Wolverines live up to tough reputation
(12/05/2011) In the first X-Men film, the comic book character Wolverine is asked if it hurts when his claws retract from his knuckles. His unflinching response: "Every time." The real wolverine (Gulo gulo) is just as tenacious with new research proving it is a "winter endurance athlete." Eight years of radio-tracking 30 individual wolverines in the Rocky Mountains has provided an abundance of new data about the world's largest member of the weasel family, including that the feisty mammals survive year-round in harsh, snowy conditions 9,000 feet above see level. Although immeasurably tough, the animal is nearly extinct in the lower 48 states of the U.S.
Global carbon emissions rise 49 percent since 1990
(12/04/2011) Total carbon emissions for the first time hit 10 billion metric tons (36.7 billion tons of CO2) in 2010, according to new analysis published by the Global Carbon Project (GCP) in Nature Climate Change. In the past two decades (since the reference year for the Kyoto Protocol: 1990), emissions have risen an astounding 49 percent. Released as officials from 190 countries meet in Durban, South Africa for the 17th UN Summit on Climate Change to discuss the future of international efforts on climate change, the study is just the latest to argue a growing urgency for slashing emissions in the face of rising extreme weather incidents and vanishing polar sea ice, among other impacts.
Environmental news in review: Keystone pipeline delayed, Dole exits banana project, a rhino goes extinct
(12/02/2011) November 2011 was a big month for environmental news stories. Topping the list was the Obama Administration's decision to delay the controversial Keystone pipeline which would have carried tar sands oil from Canada to the Gulf Coast. The scheme was vehemently opposed by environmental groups which turned the issue into a litmus test for Obama, whose campaign platform included a promise to take action on greenhouse gas emissions. More than 1,200 protesters were arrested in demonstrations leading up to Obama's decision.
Africa, China call out Canada for climate betrayal
(12/01/2011) Purchasing a full page ad in the Canadian paper the Globe and Mail, a group of African leaders and NGOs is calling on Canada to return to the fold on climate change. Canada has recently all-but-confirmed that after the ongoing 17th UN Summit on Climate Change in Durban, South Africa, it will withdraw entirely from the Kyoto Treaty. The country has missed its targets by a long-shot, in part due to the exploitation of its tar sands for oil, and is increasingly viewed at climate conferences as intractable and obstructive. In the eyes of those concerned about climate change, Canada has gone from hero to villain. Yet notable African activists, including Archbishop Desmond Tutu, are pushing back.
Top 20 banks that finance big coal
(11/30/2011) A new report from civil and environmental organizations highlights the top 20 banks that spend the most money on coal, the world's most carbon-intensive fossil fuel. Released as officials from around the world meet for the 17th UN Summit on Climate Change in Durban, South Africa, the report investigated the funding practices of 93 major private banks, finding that the top five funders of big coal are (in order): JPMorgan Chase, Citi, Bank of America, Morgan Stanley, and Barclay's.
Another record breaker: 2011 warmest La Niña year ever
(11/30/2011) As officials meet at the 17th UN Climate Summit in Durban, South Africa, the world continues to heat up. The UN World Meteorological Organization (WMO) has announced that they expect 2011 to be the warmest La Niña year since record keeping began in 1850. The opposite of El Nino, a La Niña event causes general cooling in global temperatures.
Carbon credit market for HFC-23 racked by fraud
(11/30/2011) An effort to decrease emissions of the super greenhouse gas HFC-23 has led to a largely-false carbon market that should be eliminated, argues the Environmental Investigation Agency (EIA). HFC-23 is a byproduct of the refrigerant HCFC-22, which is currently being phased out under the Montreal Protocol for its ozone-depleting and greenhouse gas properties. However, the effort to reduce HFC-23 through a carbon market has been hampered by companies in India and China producing extra HFC-23 just so they can capture and destroy it—and receive lucrative carbon funds.
For poor, climate change "a matter of life and death"
(11/29/2011) In opening the 17th UN Climate Summit in Durban, South Africa yesterday, Jacob Zuma, president of the host country said that delegates must remember what is at stake.
Featured video: are hydroelectric dams a solution to climate change?
(11/28/2011) A new video from NGOs International Rivers and Friends of the Earth International argues that a spree of dam building in the tropics is a false solution to the climate crisis. The video has been released to coincide with the UN's 17th Climate Summit now beginning in Durban, South Africa.
The Pope hopes for responsible climate deal
(11/28/2011) Pope Benedict XVI called for a "responsible" deal at the Vatican today just ahead of the two week Climate Summit in Durban, South Africa.
Deforestation could be stopped by 2020
(11/28/2011) If governments commit to an international program to save forests known as REDD+, deforestation could be nearly zero in less than a decade, argues the Living Forests Report from the World Wide Fund for Nature (WWF). REDD+, which stands for Reduced Emissions from Deforestation and Degradation, is a program that would pay developing nations to preserve forests for their ability to sequester carbon. Government officials begin meeting tomorrow in Durban, South Africa for the 17th UN climate summit, and REDD+ will be among many topics discussed.
Greenhouse gases hit new record in atmosphere as officials head to UN climate summit
(11/28/2011) The concentration of greenhouse gases in the atmosphere hit a new record in 2010, according to the UN's World Meteorological Organization (WMO), which found that warming from greenhouse gases rose 29 percent from 1990 to 2010. The announcement was made just a few days prior to officials meet at the 17th Climate Conference in Durban, South Africa, where expectations are low for a strong, binding agreement with a number of wealthy nations stating they expect no new agreement to take affect until 2020.
Arctic sea ice melt 'unprecedented' in past 1,450 years
(11/24/2011) Recent arctic sea ice loss is 'unprecedented' over the past 1,450 years, concludes a reconstruction of ice records published in the journal Nature.
Discovery Channel cuts climate change episode from Planet Earth follow-up
(11/17/2011) The new series Frozen Planet, by the creators of the super-popular and universally-acclaimed Planet Earth, details the wildlife and changing nature of the world's poles: the Antarctic and the Arctic. But while the four-year production filmed seven episodes, American audiences will only be treated to six. Discovery Channel has dropped the last episode that deals specifically with climate change.
Civilization shifting: a new leaderless era
(11/15/2011) For well over a decade global change scientists have ushered calls for urgent alteration in what they refer to as the “Business-as-Usual (BAU) paradigm” to cope with the interlinking social, economic, and environmental issues of the 21st Century. In 2001, one of the world’s largest Earth Science collaborative organizations, the International Geosphere-Biosphere Program (IGBP), published their "A Planet Under Pressure" summary report for policy makers.
IEA warns: five years to slash emissions or face dangerous climate change
(11/13/2011) Not known for alarmism and sometimes criticized for being too optimistic, the International Energy Agency (IEA) has warned that without bold action in the next five years the world will lock itself into high-emissions energy sources that will push climate change beyond the 2 degrees Celsius considered relatively 'safe' by many scientists and officials.
Obama Administration bows to pressure, delays tar sands pipeline
(11/10/2011) In what can only be described as a major victory for green activists, the Obama Administration has announced it will delay a decision on TransCanada's controversial Keystone XL pipeline for 12-18 months. Notably, putting the decision off until after the last election. The delay comes less than a week after about 12,000 people encircled the White House in opposition to the Keystone XL pipeline, which they argue threatens one of the most important water supplies in America's heartland and will worsen climate change.
12,000 surround White House to protest tar sands pipeline
(11/07/2011) One year to the day before the 2012 US election, up to 12,000 activists encircled the White House to protest the Keystone XL pipeline, a proposed 1,700 mile pipeline that would carry oil from Canada's infamous tar sands to the US and other foreign markets. Critics of the TransCanada pipeline have warned of potential spills in America's heartland as well as the climate impacts of allowing more tar sands oil, which has a higher carbon footprint than conventional sources, into the US and other markets. The issue has galvanized climate and environmental activists in the US with the massive rally on Sunday preceded by civil disobedience actions in late summer that lead to the arrests of 1,253 people.
