`Smoking gun' for global climate change published in Science
NEW YORK A NASA climatologist calls a new study the "smoking gun" that should dispel doubts about global warming.Using new data from space satellites and the depths of the ocean, researchers confirmed that the earth is absorbing more heat than it is giving off.
The lead scientist, James Hansen, says the scientists also predict global temperatures will rise by one degree Fahrenheit in this century even if greenhouse gas emissions were to be capped at once.
If carbon dioxide levels continue to grow, he says in the article published in the journal Science, things will be much worse, with ocean levels rising from the melting of ice sheets in Greenland and Antarctica.
Nearly two-thousand sensors placed in the oceans helped collect the data.
