Wetter atmosphere points to global warming
- Citat :
- THE discovery that greenhouse gas emissions are making Earth's atmosphere wetter is adding weight to the argument that global climate change is upon us.
When the Intergovernmental Panel on Climate Change first announced in 1996 that the balance of evidence suggested that human-induced climate change had begun, sceptics pointed out that the data showed only an increase in global temperature.
To make a convincing case, they argued, climatologists needed to show that other, related aspects of climate such as winds and moisture were also changing as a result of greenhouse gas emissions.
Benjamin Santer, a climate scientist at Lawrence Livermore National Laboratory in California, and his colleagues studied satellite measurements of the water content of the atmosphere. They found that total moisture content over the oceans had increased since satellite records began in 1988, but the question remained whether or not this was due to human activity.
