Greenland’s Rapid Ice Melt Could Jeopardize Major Cities

Greenland’s Rapid Ice Melt Could Jeopardize Major Cities

Sea level rise caused by rapidly melting ice sheets in Greenland is now even more likely to adversely impact the most vulnerable coastal cities: Shanghai, Hong Kong, Osaka (Japan), Rio de Janeiro, and Miami, according to a news report in The Guardian.  A new study published by the National Academies of Sciences led by scientists from Ohio State found that ice loss between 2003 and 2013 was greater than previously thought because in addition to glaciers, a greater amount of melting during that time came from ice sheets in the southwest region of the island, which is largely glacier-free and had not been as closely studied in the past.

Oceans Warming Much Faster Than Previously Thought

Oceans Warming Much Faster Than Previously Thought

Oceans are heating up at a rate as much as 40% faster than the global consensus of scientists studying climate change had previously predicted.  A team of scientists looking at the numerous recent studies which made that claim have now validated those studies’ conclusions based on ocean heat content (OHC) observations (actual ocean temperature data), according to a new report published in the journal Science on Friday.  It also validates (as if we needed more proof) that the planet is clearly warming.  

Why This Matters:  Science matters.  The more data scientists have to work with, the better they can understand the changes that are wreaking havoc with our planet.  With more ocean observing sensors, which could be much more beneficial if we expanded the network of buoys and added sensors to more ships, we would not have to fill in nearly so many gaps and could do a much better job of forecasting risks and impacts, such as sea level rise, coral bleaching, and ocean acidification.  As the experts who conducted the review said, “There is a clear need to continue to improve the ocean observation and analysis system to provide better estimates of OHC, because it will enable more refined regional projections of the future.”

Why isn’t climate change seen as geopolitical risk?

Why isn’t climate change seen as geopolitical risk?

Yesterday the Eurasia Group, a political risk consultancy released its annual list of top geopolitical risks for 2019. While themes like cyberwarfare, the US-China relationship, and the rise of populism made the ranking we were surprised to see that there was no mention of climate change.
