Bangladeshi villagers rebuild an embankment after cyclone Aila hit in 2009. Bangladesh faces total losses of about 3-4% of GDP due to climate change.
The National Academy of Sciences charter commits the Academy to provide scientific advice to the government “whenever called upon” by any government department. The Academy receives no compensation from the government for its services. The National Academy of Sciences (NAS) is a private, non-profit society of distinguished scholars. Established by an Act of Congress, signed by President Abraham Lincoln in 1863, the NAS is charged with providing independent, objective advice to the nation on matters related to science and technology.
Posted on 5 January 2012 by dana1981 Let's take a step back and have a look at what the data say about the warming of the Earth's climate . Rising Heat Content The most relevant figure when talking about global warming is the Earth's total heat content. Data from Church et al. (2011) recently updated this picture, showing that total global heat content continues its steady climb upwards. As Figure 1 shows, most of this heat (about 90%) has gone into the oceans, and the continuing rise of both global and ocean heat content is probably the best indicator that global warming hasn't even slowed down.
Not for Experts are occasional presentations from the Tyndall Centre aimed at explaining the underlying principles of climate change research. They originate as webcasts to the Tyndall (early career) Researcher Network to help train their interdisciplinary understanding of climate change research. The Physical Basis of Climate Change, Professor Corinne Le Quéré This first Not for Experts is by the Director of the Tyndall Centre, Professor Corinne Le Quéré. Professor Le Quéré explains how climate data is collected and assembled, how it is used by modellers to assess the human contribution to recent climate change, and how it is synthesized by the Intergovernmental Panel on Climate Change, and reveals the recent trends to 2011 where data is available. <div class="disqus-noscript"><a href="http://tyndallcentre.disqus.com/?
The most important indicator of global warming, by far, is the land and sea surface temperature record. This has been criticized in several ways, including the choice of stations and the methods for correcting systematic errors. The Berkeley Earth Surface Temperature study sets out to do a new analysis of the surface temperature record in a rigorous manner that addresses this criticism. We are using over 39,000 unique stations, which is more than five times the 7,280 stations found in the Global Historical Climatology Network Monthly data set (GHCN-M) that has served as the focus of many climate studies.
