Arctic Ice Update 2016

This is my fourth annual Arctic ice update. Once in a while, we pass a new milestone in our race to destroy our environment. The year 2012 was such a time, when the Arctic sea ice reached a record low extent. This year, things are getting a little crazy, probably due to the influence of... Continue Reading →

Arctic Ice Update 2015

Volume gives you the most useful information, in terms of how much ice is left and how fast it is diminishing, but it is also the hardest to measure accurately. To get an idea of...

Unfortunately, the heat content of Earth continues to rise unabated, with most of the increase currently going into the oceans rather than... Continue Reading →
