Water cycle amplifies abrupt climate change
2014-01-20 03:59:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: During the abrupt cooling at the onset of the so-called Younger Dryas period 12680 years ago changes in the water cycle were the main drivers of widespread environmental change in western Europe. Thus, the regional impacts of future climate changes can be largely driven by hydrological changes, not only in the monsoonal areas of the world, but also in temperate areas. The role of the hydrological cycle during abrupt temperature changes is of prime importance for the actual impact of climate change...

Looming Danger of Abrupt Climate Change
2013-12-26 10:15:00| Climate Ark Climate Change & Global Warming Newsfeed
CounterPunch: The National Research Council of the National Academies (NRCNA) has pre-published (available to the public as of Dec. 2013), an extensive 200-pg study: Abrupt Impacts of Climate Change, Anticipating Surprises. The goal of the report is to prepare society to anticipate the otherwise unanticipated before it occurs, including abrupt changes to the ocean, atmosphere, ecosystems and high latitude regions. The NRCNA timescale for abrupt climate change is defined as years-to-decades. The history...

Earth's climate: 'Abrupt change is already underway.'

Daily Maverick: For years now, people have argued over both the reality and nature of climate change on our Earth. Scientists, mostly, have increasingly argued the preponderance of evidence points strongly towards a significant change in global climate in the offing. Meanwhile, politicians, mostly, have argued it isnt happening, and, anyway, if even it is, it is not from the hand of mankind. Now a high-level American scientific body, the National Research Council, has thrown its full public weight behind the fact...

US National Research Council wants abrupt climate change warning system
2013-12-05 03:51:00| Climate Ark Climate Change & Global Warming Newsfeed
Ars Technica: Yesterday, the National Research Council (a branch of the US' National Academies of Science) released a report in which it called for the creation of an early warning system that would let us know when we're approaching tipping points in the climate. While talk of climate tipping points is fairly common, most of it focuses on the climate itself changing to a new state. The new report is quite different, in that it's focused on things that can enter new states even when the climate is only changing...

Abrupt Climate Change Raises Concerns
2013-12-03 22:24:00| Climate Ark Climate Change & Global Warming Newsfeed
Voice of America: A National Research Council report is raising concern about the increased potential for abrupt climate changes in the near future, meaning change in a few years or decades - rather than centuries - leaving little time for society and ecosystems to adapt. University of Colorado Geological Sciences Professor Jim White led the scientific committee assessing the risk. "It is important to recognize that not only does climate change itself, but there are impacts, on human systems and on natural ecosystems,...
