Check out the daily weather map for some relevant close-up information (which changes daily):
The first image shows that today’s actual average temperatures hundreds of miles north of Scandinavia are no different from those in the central part of the US, which have been fairly mild for the season. The relationship has been that way for more than a week lately—extremely unusual. Then click on “Temperature Anomaly” and scroll down to the full global view. I have never seen anything like it, not even close, with the overall extremes now in their third consecutive day. The full world anomaly of 1.01C has literally jumped one-half degree from the area where it usually sits, going as far back as I can remember. The sea surface anomaly has meanwhile not budged, so maybe the air temperature data has somehow been compromised? Stay tuned.

One more paleoclimate story, this time about new research. This takes us back 252 million years, describing an investigation into the cause of history’s greatest mass extinction. The effort paid off by providing new data on the date, duration and powers of the massive Siberian basalt flood, perfectly timed to be the cause. Another mass extinction event initiated in Antarctica 182 million years ago was found to have a similar origin.
