NCSE is pleased to announce the debut of a new resource in the climate change section of its website: "Voices for climate change education." Following the model of Voices for Evolution , NCSE's unique collection of organizational statements endorsing the teaching of evolution, "Voices for climate change education" assembles organizational statements endorsing the teaching of climate change. Included so far are extracts from the National Research Council, the US Global Change Research Program, the National Association of Geoscience Teachers, the American Geological Institute, the American Geophysical Union, the Geological Society of America, the American Chemical Society, and UNESCO. The full text of these statements will be added in the future. So will further organizational statements endorsing the teaching of climate change — so if you spot any, be sure to let NCSE know !

Facts, numbers, data, letters on a page, they're not always so easy to understand. Over the past few years data visualisation has become increasingly popular; it's a way to help explain complex data. Here are two alternative ways to show how the extent of Arctic sea ice has changed over the past 20 years.

BBC News - Climate sensitivity to CO2 probed
Models are used to project future climatic scenarios Global temperatures could be less sensitive to changing atmospheric carbon dioxide (CO2) levels than previously thought, a study suggests. The researchers said people should still expect to see "drastic changes" in climate worldwide, but that the risk was a little less imminent. The results are published in Science . The study is the latest to derive a value for "climate sensitivity" - the temperature rise for a doubling of CO2 concentrations - from palaeontology.
Born in Lithuania in 1926, Aaron Klug is a British chemist and biophysicist, was awarded the Nobel Prize in Chemistry in 1982 for developments in electron microscopy and his work on complexes of nucleic acids and proteins. He studied crystallography at the University of Cape Town before moving to England, completing his doctorate in 1953 at Trinity College, Cambridge. In 1981, he was awarded the Louisa Gross Horwitz Prize from Columbia University. His long and influential career led to a knighthood in 1988. He was also elected President of the Royal Society, and served there from 1995-2000.
Aaron Klug - Global warming: the greenhouse effect - Web of Stories
ScienceDaily (July 5, 2011) — The question seems simple enough: What happens to Earth's temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record.

For Climate Change Adaptation, Traditional Knowledge is Critical | Conservation International Blog
Sarshen Marais is currently attending the United Nations Framework Convention on Climate Change (UNFCCC) meeting in Bonn, Germany . Here, she blogs about a side event on traditional knowledge and climate change adaptation, an event presented by CI, UNESCO , the Indigenous Peoples of Africa Coordinating Committee and the UN’s World Meteorological Organization (WMO) .

Dr. Richard Feely of NOAA’s Pacific Marine Experimental Lab discusses new findings about how increased carbon dioxide in the atmosphere is making the oceans more acidic, and what that bodes for ocean ecosystems and the marine animals that inhabit them.

These include total emissions, per capita emissions, historical emissions and emissions as measured by consumption as opposed to production.
Which nations are most responsible for climate change? | Environment | guardian.co.uk
The best way to promote clean energy is to ignore climate change and focus on things like jobs, money and national security IN THE 1970s everyone thought environmentalism meant granola, which meant health food stores, which meant carob, a horrible substance the health-foodies told us we should eat instead of chocolate. In the same decade, US president Jimmy Carter reduced the speed limit on interstates from 70 miles per hour to 55 mph to save energy. Carter got kicked out and carob made it feel like "doing the right thing" was akin to taking medicine: the environmental movement was saddled with pseudo-chocolate and painfully slow driving. Now motoring is going electric, not because of its moral compass - it's just that the engines perform much better.

Climate, Energy & Transport | World Resources Institute
Increasingly frequent extreme weather events, record annual global average temperatures and disruptive seasonal changes in vulnerable countries all point to increasing evidence of anthropogenic climate change. Continued reliance on outdated energy sources, coupled with a growing population and the emergence of a global middle class, put the world on a pathway to experience climate impacts of a dangerous and irreversible magnitude. This fossil fuel-based growth trajectory of the last century is no longer sustainable or economically viable.

Déjà onze mois que nous arpentons les sentiers des Andes, et nous voilà enfin arrivées sur les rives du fameux lac Titicaca. Sa réputation est grande, principalement pour sa situation géographique assez exceptionnelle: perché à en moyenne 3812m d’altitude, c’est le plus haut lac navigable au monde ! Selon la légende, il serait le berceau...File this one in the interestingly geeky diversion category: Coming to TreeHugger via The Cost of Energy is what they are calling the "coolest looking graph in climate science"--which helps visualize why global average temperatures are rising, oceans are becoming more acidic, the weather's getting weirder, and the whole shebang of other climate change effects we're currently experiencing and will continue to experience.There's a whole lot crammed onto that small YouTube video size, so here's what you're be looking at: That moving line on the left represents atmospheric CO2 as measured at various places around the globe--the red dot is at Mauna Loa in Hawaii; the blue one is at the South Pole; the grey ones are at various locations that pop up on the map in the upper right. The spinning clock at middle right represents time in years and months. The trend should be clear.

A surge in gas and oil drilling in the U.S. is helping drive the economic recovery and is enhancing energy security. But as the situation in Ohio shows, cheaper energy prices and the focus on fossil fuels has been bad news for the renewable energy industry. A physicist argues that if we allow our overblown and often irrational fears of nuclear energy to block the building of a significant number of new nuclear plants, we will be choosing a far more perilous option: the intensified burning of planet-warming fossil fuels. by jim robbinsThe G-Econ research project is devoted to developing a geophysically based data set on economic activity for the world. The current data set (GEcon 4.0) is now publicly available and covers "gross cell product" for all regions for 1990, 1995, 2000, and 2005 and includes 27,500 terrestrial observations. The basic metric is the regional equivalent of gross domestic product. Gross cell product (GCP) is measured at a 1-degree longitude by 1-degree latitude resolution at a global scale. Updates will be posted as they become available. The project staff is Professor William Nordhaus, Yale University, and Professor Xi Chen, Quinnipiac University.
