The American Geophysical Union (AGU) is conducting a survey "to better understand how recent U.S government policy is impacting your science. Specifically, how will sequestration and/or government travel restrictions affect your ability to conduct research, attend conferences, and participate in AGU activitiesThis is a follow-up to a similar survey conducted in March 2013, which was distributed via AGUniverse. This information will help us to communicate more specifically with policy makers and to support and facilitate your full participation in AGU volunteer activities and meetings."

Sensitive information: A peek inside the next IPCC assessment. "'That report is going to scare the wits out of everyone,' said Yvo de Boer recently. He is a former United Nations chief climate negotiator and was talking about the forthcoming fifth assessment by the Intergovernmental Panel on Climate Change (IPCC). With two months to go before the assessment is to be published, however, one sign suggests it might be less terrifying than it could have been. The sign in question is about climate sensitivity. This is the measure used by researchers of how much they expect the world's average temperature to increase in response to particular increases in levels of carbon dioxide in the atmosphere. According to one table from the unpublished report, at CO2 concentrations of between 425 parts per million and 485 ppm, temperatures in 2100 would be 1.3-1.7
