Earlier this month the National Oceanic and Atmospheric Administration (NOAA) released their 2012 report card on the Arctic and to no surprise the news is sobering.
--Record low snow and sea ice extent in June and September.
--Record high permafrost temperatures across northernmost Alaska.
--Record longest duration of melting on the Greenland Ice Sheet.
--Massive phytoplankton blooms below summer sea ice.
--Several severe weather events.

A particular climate geoengineering effort to reduce the amount of sunlight might not work out.....
Understanding the climate model.
A look at the model projected long-term changes in global temperatures and precipitation based on a combination of four greenhouse gas emission scenarios.
Going back 10,000 years, researchers have determined that the Greenland Ice Sheet was actually at its smallest size between three and five thousand years ago.
Observed changes in global precipitation are directly affected by human activities and cannot be explained by natural variability alone.
Better late than never. Here is the global October 2013 satellite measured temperature anomaly data
