Climate Scientist Warns Sea Levels Are Rising Faster Than We Thought

SOURCE: Think Progress DATE: July 20, 2015 AUTHOR: Samantha Page SNIP: Limiting climate change to 2°C is not going to protect us from devastating sea level rise, a new report has found. According to the research, freshwater from land-based ice sheets melting into the oceans is inducing feedback that is accelerating the melting of ice shelves — a loop that indicates sea level rise will continue and could be devastating at much lower temperature changes than previously thought. The study, authored by well-known climate scientist James Hansen and 16 other researchers, will be published in Atmospheric Chemistry and Physics this week. The research explains that there is an “amplifying feedback” as polar ice melts, because as more freshwater enters the ocean, it traps warmer sea water, which melts more ice. The effect is not included in the currentIntergovernmental Panel on Climate Change (IPCC) modeling but “extensive data indicate [it] is already occurring,” according to the...

Arctic sea ice is getting thinner faster than expected

SNIP DATE March 5th 2015 SOURCE The Guardian While the steady disappearance of sea ice in the Arctic has been one of the hallmark effects of global warming, research shows it is not only covering less of the planet, but it’s also getting significantly thinner. That makes it more susceptible to melting, potentially altering local ecosystems, shipping routes and ocean and atmospheric patterns. New data compiled from a range of sources – from Navy submarines to satellites – suggests that thinning is happening much faster than models have estimated, according to a study aiming to link those disparate data sources for the first...
