Science: Wheres the heat? Greenhouse gases, particularly carbon dioxide, continue to be pumped into the atmosphere, but sometime around 1998, the rise in Earths average temperatures slowed, deviating from the rates predicted by models. Scientists have proposed that what some call the pause could be the result of a number of factors, including heat storage in deep ocean waters to unexpectedly high amounts of aerosols in the stratosphere helping deflect solar rays back into space. Now, a new study suggests...
