Scientists simulate climate’s worst case scenario

What happens if the human population continues to grow and nothing much changes in the way we curb fossil fuel use? Climate models these days have largely focused on scenarios that assume some level of restraint on greenhouse emissions, with particular emphasis on the political goal of keeping global temperatures no higher than 2 degrees above pre-industrial levels.  But scientists at the National Center for Atmospheric Research in Boulder and the Institute for Atmospheric and Climate Science... [Read more]

Research jets return with wealth of data on greenhouse gases

Black carbon particles in the Western Pacific are at levels comparable to megacities like Houston and Los Angeles because they are floating widely throughout the atmosphere. These dark colored particles, which form from incomplete combustion, are one of the major contributors to climate change by absorbing solar radiation and by causing snow and ice to melt faster. The discovery is just one of a number that’s expected to come out of the far-reaching expedition called HIPPO (HAIPER Pole-to-Pole... [Read more]

Rapid increases in greenhouse gases part of Earth’s history

Rapid increases in greenhouse gases have happened more frequently in the Earth’s history than previously realized, according to a Scripps Institution of Oceanography-led study published last week in the journal Nature. Scientists have studied extensively the the Palaeocene-Eocene Thermal Maximum (PETM), about 56 million years ago, a period of rapid global warming that’s associated with a temperature spike on par with expectations for today’s global warming scenarios. But according... [Read more]
