Worse...they ignore their own data.
The Sun's magnetic field is in decline....so less sunspots.
Last time this happened there was a 400 year long mini ice age (1350 to 1750).
In reality the "worm hole explorers"were forced out because of crop failures caused by global cooling.

The official view in Norway is in contrast to what the people experience because of cooling weather:
Late spring gives flooding and avalanches when late snow-melting in the mountains.
Water pipes freeze because of early and deep frost in the winter.
Insect populations down 40% in 5 years because of cool and wet summers. This of cause is bad for pollination of fruit and berries. The grain harvest in Norway this summer is down 18% from average the last 5 years, despite increase in area and better seeds. But officially it is getting warmer.

That doesn’t look anything like mann’s hockey stick. :>}
