4-5 Foot Sea Level Rise More Likely by 2100reports Joe Romm at Climate Progress. Several new studies underscore scientists’ concerns we’re headed toward sea level rise of 4 to 5 feet by 2100 — and ultimately toward a 69-foot rise over many hundreds of years due to the unstoppable melting of Antarctic and Greenland glaciers.

NASA’s glaciologist Eric Rignot notes that taken together, the new papers “suggest that the globe’s ice sheets will contribute far more to sea level rise than current projections show.” Also, the rate of sea level rise in 2100 could be upwards of 1 inch per YEAR!

What We’ve Bought Our Future Children: Disappearing Coasts. Some of the projected US coast lost from a 20 meter sea level rise (highlighted in red), which will occur over the coming centuries due to the unstoppable melting of Antarctic and Greenland glaciers. (Am not sure why Long Island, NY isn’t completely submerged.) This is one thing we can’t turn back – but we can stop the story from getting worse.Source: google data, via Climate Progress.

Antarctic Ice Collapse Could Devastate Global Food Supply says a new study,reports Suzanne Goldenberg at the UK Guardian. The ongoing collapse of a large part of the Antarctica ice sheet could devastate global food supply, drowning vast areas of crop lands across the Middle East and Asia, according to new research.

The report also warns that America’s corn belt could face yield declines of more than 25% by 2050 – unless there are new advances in agriculture to compensate for hotter temperatures, changing rainfall and more aggressive weeds and pests under climate change.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here. This is an ongoing campaign (the next Congressional election is this year!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
