Contribution potential of glaciers to water availability in different climate regimes


As a result of global warming glaciers are shrinking. In an article in PNAS an Austrian team of glaciologists present a global survey of the effect of glacier retreat on water supply in populated areas.

More Indonesian volcanoes active and one in the Phillippines


With casualty numbers after the eruption of Merapi steadily rising to more than 320, yet another volcano, Bromo in East Java has started to spew ash. The Ministry of Mines and Energy has given out a high alert for Bromo. The exclusion zone has been extended to 3 km, last Wednesday.

PhD position: The effect of forest management on the European carbon sink


The project aims to understand and quantify the role of forest management in mitigating climate change. Specifically, it wants to challenge the current focus on the carbon cycle only, and replace it with an overall climate impact approach. Hence, the entire forest management spectrum, ranging from short rotation crops to old-growth forests will be analysed for its effects on the water, energy and carbon cycles of the forest ecosystem.

Global Warming could cool down temperatures in winter

17.11.2010, Potsdam Institute for Climate Impact Research (PIK), Potsdam, Germany

The overall warming of the earth's northern half could result in cold winters. The shrinking of sea-ice in the eastern Arctic causes some regional heating of the lower levels of air – which may lead to strong anomalies in atmospheric airstreams, triggering an overall cooling of the northern continents, a study recently published in the Journal of Geophysical Research shows. “These anomalies could triple the probability of cold winter extremes in Europe and northern Asia,” says Vladimir Petoukhov, lead author of the study and climate scientist at the Potsdam Institute for Climate Impact Research. “Recent severe winters like last year’s or the one of 2005-06 do not conflict with the global warming picture, but rather supplement it.” (Press Release Potsdam Institute for Climate Impact Research)

Twitter chatbot argues with global warming deniers automatically


Climate sceptics often recycle the same, long refuted, arguments over and over. Nigel Leck got tired of countering their arguments and built a Twitter chatbot to answer them automatically.

Inaccurate news reports misrepresent a climate-science initiative of the American Geophysical Union


An article appearing in the Los Angeles Times, and then picked up by media outlets far and wide, misrepresents the American Geophysical Union (AGU) and a climate science project the AGU is about to relaunch. The project, called Climate Q&A Service, aims simply to provide accurate scientific answers to questions from journalists about climate science.
