1200 years of water balance data challenge climate models
2016-04-07 07:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Water availability in the Northern Hemisphere has seen much larger changes during the past twelve centuries than during twentieth century global warming, a new study in Nature reports. The team with participation of the Swiss Federal Research Institute WSL concludes that climate models overestimate wet and dry extremes as temperatures increased during the twentieth century. The new results can help to improve the ability of climate models to predict future hydroclimate changes. The researchers from...

Gag order climate change cant stop water from rising to our doorstep

Press Herald: Dear Florida Gov. Rick Scott: So it turns out the experts were mistaken. It turns out the impact of climate change on Florida and much of the coastal United States is not going to be anywhere near as bad as had been predicted. Apparently, its going to be much worse. Thats the sobering finding of a study published this week in the journal Nature Climate Change. Previous scenarios, grim as they were, failed to take into account projected population growth. Factor that in, say the researchers,...
Climate change redistributes global water resources

PhysOrg: Analysis of more than 40 years of water samples archived at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire tells a vivid tale of how the sources of precipitation have changed. Over the years, there has been a dramatic increase, especially during the winter, of the amount of water that originated far to the north. "In the later years, we saw more water derived from evaporation of the Arctic and the North Atlantic oceans," said Tamir Puntsag, a graduate student at the SUNY College...

Climate: Land areas storing more water, slowing sea level rise
2016-02-13 08:40:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit County: As crucial as it is for the future of humanity, calculating the rate of sea level rise has never been easy, and new measurements by NASA satellites have added a new twist to the equation. Careful study of the data from NASA`s twin NASA`s Gravity Recovery and Climate Experiment (GRACE) satellites helped show how climate-driven increases of liquid water storage on land have affected the rate of sea level rise. In the past decade, Earth`s land masses have soaked up an extra 3.2 trillion tons of water...
Worldwide electricity production vulnerable to climate and water resource change
2016-01-04 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Climate change impacts and associated changes in water resources could lead to reductions in electricity production capacity for more than 60% of the power plants worldwide from 2040-2069, according to a new study published today in the journal Nature Climate Change. Yet adaptation measures focused on making power plants more efficient and flexible could mitigate much of the decline. "Hydropower plants and thermoelectric power plants--which are nuclear, fossil-, and biomass-fueled plants converting...
