Climate change? Atmospheric scientists have no doubts about it

Earlier this week, the 200 top climate scientists, along with a few economists and politicians, assembled at Britain's Met Office, one of the world's leading providers of environmental and weather-related services. Their message: it's time for the politicians to take steps to lower emisions of carbon dioxide and other greenhouse gases. According to Stanford University's Michael Mastrandrea, "We don't really need more detail now. We already have enough information to make an educated guess on how we need to reduce emissions."

In the last 10 years, researcher have made many predictions about the effects of climate change. Larry Hughes, an environmental researcher from Dalhousie University in Halifax, Canada says that researchers agree that many of these predictions have come true, such as thermal expansion of the oceans, acidification of water, increased air temperatures, and more storm activity. "And it is apparent that things aren't getting better," says Robert Socolow, co-director of the Carbon Mitigation Initiative at Princeton University in New Jersey. "What we can tell politicians is that the list of worries is going to grow." Link.
