Global warming - naturally

"Much of ...the Arctic warming during the last half century is due to natural change" - Syun-Ichi Akasofu, director of the International Arctic Research Centre, University of Alaska

Lawrence Solomon highlights Dr. Akasofu’s work today in the National Post’s The Deniers - Part XVII:
....over the course of the 20th century, global temperatures increasing by about half a degree Celsius.
[...]
...over the course of the 19th century, too, global temperatures again increasing by about a half a degree Celsius.
[...]
...over the course of the 18th century, too, global temperatures increasing by about a half a degree Celsius.
[...]
...over the course of the latter part of the 17th century as well, global temperatures increasing at the rate of about a half a degree Celsius per century.
Hmmm! Do I detect a pattern here?

These hints come from "ice core data from the Arctic island of Severnaya Zemlya, published just last year" and from "multiple other sources".

Dr. Akasofu, says his work indicates "The Earth may still be recovering from the Little Ice Age."

Furthermore, IPCC climate model ‘hindcasting’ fails to produce results matching the actual observations leading to the conclusion that "arctic warming and cooling is not caused by the greenhouse effect".

Solomon's series is a treasure trove of information. More proof that there's no "consensus" on climate change - as if that really mattered.

What matters is that the warming we're experiencing is totally natural and not at all unusual. Life on earth has adapted through climate change throughout history - and it will once again.
