Comparing climate projections to observations up to 2011 - Abstract - Environmental Research Letters
We analyse global temperature and sea-level data for the past few decades and compare them to projections published in the third and fourth assessment reports of the Intergovernmental Panel on Climate Change (IPCC). The results show that global temperature continues to increase in good agreement with the best estimates of the IPCC, especially if we account for the effects of short-term variability due to the El Niño/Southern Oscillation, volcanic activity and solar variability. The rate of sea-level rise of the past few decades, on the other hand, is greater than projected by the IPCC models.
Can Carbon Dioxide Be A Good Thing? -- Physicist Explains Benefits Of Carbon Dioxide
June 1, 2007 — A physicist from Colorado State University and his colleagues from the North American Carbon Program (NACP) have discerned and confirmed the unforeseen advantages of rising carbon dioxide levels. Through the processes of photosynthesis and respiration, scientists have been able to elucidate why plants are growing more rapidly than they are dying. The NACP is employing methods, such as the use of cell phone and aircraft towers to monitor and retrieve carbon data for their continuing study. Too much carbon dioxide can be a bad thing, but sometimes it can have a positive effect on plants and trees.This web page will introduce and lead you through the content of the most comprehensive and authoritative report of its kind. The Second National Climate Assessment, entitled Global Change Impacts in the United States , summarizes the science and the impacts of climate change on the U.S., now and in the future. This report focuses on climate change impacts in different regions of the U.S. and on various aspects of society and the economy such as energy, water, agriculture, and health.
