Response To ?Hot Topic?

I wrote an article for SPPI a couple of weeks ago titled ?To a Geologist, ?The Past is Key to the Future.? I got some good feedback from it, none more flattering than being compared to Lord Monckton by Hot Topic NZ

Unfortunately, they got a few other things wrong.

Point 1. Antarctic sea ice has been increasing steadily through the satellite record. No one disputes this.

Point 2. Greenland is not as warm as it was 70 years ago. Dr. Walt Meier at NSIDC said this :

The current Greenland warming, while not yet quite matching the temperatures of 70 years ago, is part of a global warming signal that for the foreseeable future will continue to increase temperatures (with of course occasional short-term fluctuations), in Greenland and around the world.

Hot Topic cited some above normal temperatures earlier in the year, and ignored the long term trend. They ignored the fact that there are only a very small number of stations with contiguous records going back 100 years. They ignored the map I included showing the regions of GISS cooling (turquoise) over the last 70 years.

When cherry picking the 2010 temperature dates they were willing to look at, they ignored the fact that Greenland is having extremely cold weather this autumn. Temperatures close to 70 below zero on the ice sheet already this October, and are forecast to remain that way for weeks. They also ignored the fact that Greenland has been on a cooling trend since 2007.

Point 3. There is no question that the satellite record coincides with the warm phase of the PDO. Ridiculous of them to dispute this well known fact.

Point 4. They offered no evidence tying the current Arctic warming to CO2. If it is due to CO2, why is it colder now over most of the Arctic than it was 70 years ago?

It is difficult to argue against ad homs, but easy to discuss the science.
