The oceans have warmed in the past 50 years, but not by natural events alone. New research by a team of Lawrence Livermore National Laboratory scientists and international collaborators shows that the observed ocean warming over the last 50 years is consistent with climate models only if the models include the impacts of observed increases…

Earth’s global temperature has been rising gradually over the last decades, but the warming has not been the same everywhere. Scientists are therefore trying to pin down how the warming has affected regional climates because that is what really matters to people, and to adaptation and mitigation strategies. Their efforts, however, had hit a roadblock…

Meteorologists at Freie Universität have found a correlation between warming in the stratosphere and cold or warm winter periods. They observed that there is an increased number of stratospheric warmings, when the heat flow from the North Atlantic into the atmosphere is increased. Trends for winter temperatures can be derived from these new findings. “This…
