The Antarctic Canary — the human impact on climate changeSeptember 05, 2006British Antarctic Science Festival As the UK attempts to move towards a low carbon economy, leading scientists and a world expert on sustainable energy in buildings this week discuss the evidence for climate change and possible solutions. A public seminar - 'the Antarctic Canary - the human impact on climate change' at the BA Festival of Science in Norwich will be held on Monday 4 September. Evidence from an 800,000-year Antarctic ice core record shows unprecedented atmospheric change due to carbon dioxide and other greenhouse gases. Dr Eric Wolff from British Antarctic Survey (BAS), leader of the science team for the European Project for Ice Coring in Antarctica (EPICA) says,
"Ice cores reveal the Earth's natural climate rhythm over the last 800,000 years. When carbon dioxide changed there was always an accompanying climate change. Over the last 200 years human activity has increased carbon dioxide to well outside the natural range and we have no analogue for what will happen next." Although large increases in carbon dioxide may be alleviated by natural sinks in the ocean and on land, a critical issue is how these sinks will behave in the future. For the last 15 years international scientists, including the Intergovernmental Panel on Climate Change, have used research into carbon cycle by Dr Corrinne Le Quéré of UEA and BAS. She says, 'Our land and oceans may well become less efficient carbon sinks as concentrations increase. We cannot rely on them to solve the problem.' Scientific knowledge, especially about climate change, is essential for a sustainable economy. In the UK the built environment accounts for around 50% of energy consumption, with housing alone contributing around 27% of UK carbon dioxide emissions. Professor Peter Smith, University of Nottingham and author of 'Architecture in a Climate of Change', offers creative solutions to improve the energy efficiency of buildings. He says, "There is an urgent need to find innovative technologies to reduce the impact we are having on our climate. If we are committed to a low carbon economy the UK needs a vigorous twin track programme of demand reduction and renewable energy technology. Governments may have only 10 years in which to determine the destiny of our planet - giving only five years in which to develop feasibility and design studies. I am disappointed that the recent UK Energy Review totally fails to appreciate the urgency of the situation."

Climate change is already having an impact in the midwest and across the US Extreme weather, drought, heavy rainfall and increasing temperatures are a fact of life in many parts of the U.S. as a result of human-induced climate change. Berkeley Lab Scientists Contribute to Major New Report Describing Climate Change Impacts on the U.S. Two researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), Evan Mills and Michael Wehner, contributed to the analysis of the effects of climate change on all regions of the United States, described in a major report released today by the multi-agency U.S. Global Change Research Program. Alaska researchers contribute to national climate change report Two University of the Alaska Fairbanks researchers are among key contributors to a new national report that details visible effects of climate change in the United States and how today's choices stand to affect the future. Counting sheep in climate change predictions Climate change can have devastating effects on endangered species, but new mathematical models may be able to aid conservation of a population of bighorn sheep. Climate change odds much worse than thought The most comprehensive modeling yet carried out on the likelihood of how much hotter the Earth's climate will get in this century shows that without rapid and massive action, the problem will be about twice as severe as previously estimated six years ago - and could be even worse than that. Climate change makes migrations longer for birds Bird migrations are likely to get longer according to the first ever study of the potential impacts of climate change on the breeding and winter ranges of migrant birds. Relocation, relocation, relocation As sea levels rise in the wake of climate change and semi-arid regions turn to desert, people living in those parts of the world are likely to be displaced. A mathematical approach to planned relocation reported in the International Journal of Mathematics and Operational Research. Climate change affecting Europe's birds now, say researchers Climate change is already having a detectable impact on birds across Europe, says a Durham University and RSPB-led scientific team publishing their findings to create the world's first indicator of the climate change impacts on wildlife at a continental scale. British butterfly reveals role of habitat for species responding to climate change Most wild species are expected to colonise northwards as the climate warms, but how are they going to get there when so many landscapes are covered in wheat fields and other crops?
