IPCC: Climate Warming Caused by Humans, Will Persist for Centuries

Environment News Service: "Human influence on the climate system is clear. This is evident in most regions of the globe," finds a new assessment by the Intergovernmental Panel on Climate Change, IPCC, released today. "It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century. The evidence for this has grown, thanks to more and better observations, an improved understanding of the climate system response and improved climate models," states the report, the...

Seas may rise 10 yards during centuries ahead

Grist: Sea-level rise is currently measured in millimeters per year, but longer-term effects of global warming are going to force our descendants to measure sea-level rise in meters or yards. Each Celsius degree of global warming is expected to raise sea levels during the centuries ahead by 2.3 meters, or 2.5 yards, according to a study published Monday in Proceedings of the National Academy of Sciences. The world is currently trying (and failing) to reach an agreement that would limit global warming...

Centuries worth of CO2 emissions could be stored underground, but at what cost?

Grist: We could liquefy and cram our carbon dioxide emissions into the ground for some 500 years before America`s geologic basins started to overflow with the stuff. That`s according to a new assessment by federal scientists, who spent years scouring America for porous rocks thousands of feet beneath the ground that might be appropriate for carbon sequestration. They studied 36 geologic basins that could be suitable and found that the best region for storing waste CO2 would be the Gulf Coast. From...

Ancient plants reawaken: Plants exposed by retreating glaciers regrowing after centuries entom

ScienceDaily: When University of Alberta researcher Catherine La Farge threads her way through the recently exposed terrain left behind by retreating glaciers, she looks at the ancient plant remains a lot closer than most. Now, her careful scrutiny has revealed a startling reawakening of long-dormant plants known as bryophytes. La Farge, a researcher in the Faculty of Science, and director and curator of the Cryptogamic Herbarium at the University of Alberta, has overturned a long-held assumption that all of...

Plants re-grow after five centuries under the ice

Mongabay: While monitoring the retreat of the Teardrop Glacier in the Canadian Arctic, scientists have found that recently unfrozen plants, some of which had been under ice since the reign of Henry VIII, were capable of new growth. While in the field, the researchers from the University of Alberta discovered that the receding ice--which has doubled from 2 meters per year in the 1990s to 4.1 meters per year in 2009--had uncovered lots of mosses and other non-vascular plants, including more than 60 plant...
