An interesting Post at RobertScribbler discusses Polar Amplification. Record heat levels in October, along with surprisingly large increases in CO2 (at a time of the year when levels tend to stay flat). He goes on to explain how the atmospheres of Earth and Venus are different yet becoming more similar. He posts graphs showing how the average temperature differences between the equatorial and polar regions have been diminishing over recent decades. And, all of this leads to changes in the jetstreams, thus changes in normal weather patterns. It is an interesting read.
