Arctic Sea Ice

Let’s take a look at what Arctic sea ice extent has been up to over the years. We’ll use the satellite data which extend back to late 1978, rather than the MASIE data which don’t start until 2006 (especially since those who publish it recommend using the satellite data anyway).

Sleaziest Politician: Global Warming Edition

Glenn Beck recently interviewed Carly Fiorina. Here’s part of their conversation:

Exogenous Redux

A reader recently requested that I revisit the issue of adjusting temperature data to allow for known factors, the ones that don’t affect the trend but do cause fluctuations, in order better to isolate the trend changes, which are mainly due to greenhouse gases. We can call those known influences exogenous factors. I’ve dealt with this many times, and published research about it, so I’m not going to say very much about the methodology.
