6:43 PM | Biofuel, good for the environment if you’re eating less
When the government first changed policy to require ethanol in gasoline, we were told it would reduce our carbon footprint. Then food prices rose significantly and corn in particular saw the largest price rise. This was because corn is a staple in production of almost any other food from eggs to beef, but the policy made […]

6:35 PM | Antarctic Ice Shelves Melting at Accelerating Rate
Antarctica is pretty much covered with glaciers. Glaciers are dynamic entities that, unless they are in full melt, tend to grow near their thickest parts (that’s why those are the thickest parts) and mush outwards towards the edges, where the liminal areas either melt (usually seasonally) in situ or drop off into the sea. Antarctic’s…

7:20 PM | Currents in the Atlantic Ocean are slowing to dangerous levels.
Currents in the Atlantic Ocean are slowing to dangerous levels. The Gulf Stream system is now weaker than at any time before 1901, likely due to global warming. Climate scientists warn that waning circulation could dramatically change weather in Europe, cause sea level rise along the U.S. East Coast, and impact marine ecosystems. Read more...

5:27 PM | New Research Shows Exceptional Slowdown In Major Atlantic Ocean Currents
Climate scientists have noticed a disturbing pattern in the North Atlantic. This is the relative cooling of surface waters in the area fed by the Gulf Stream. This pattern has emerged over recent decades, and may portend very rapid and potentially disruptive climate change in the upcoming decades. The cooling is not subtle at all,…
