Shortening food growing season Forget global warming:

Forget global warming – If NASA scientists are right we could be headed for a mini ice age
By Robert On January 2, 2015

"The supposed ‘consensus’ on man-made global warming is facing an inconvenient challenge after the release of new temperature data showing the planet has not warmed for the past 15 years.
The figures suggest that we could even be heading for a mini ice age to rival the 70-year temperature drop that saw frost fairs held on the Thames in the 17th Century.

"The Met Office has released new temperature data showing the planet has not warmed for the past 18 years.It confirms that the rising trend in world temperatures ended in 1997.

"The figures suggest that we could be heading for a mini ice age to rival the 70-year temperature drop that saw frost fairs held on the Thames in the 17th Century.
In fact, leading climate scientists yesterday told The Mail that, after emitting unusually high levels of energy throughout the 20th Century, the sun is now heading towards a ‘grand minimum,’ threatening cold summers, bitter winters and a shortening of the season available for growing food."

"According to a paper issued last week by the Met Office, there is a 92 per cent chance that both Cycle 25 and those taking place in the following decades will be as weak as, or weaker than, the ‘Dalton minimum’ of 1790 to 1830. In this period, named after the meteorologist John Dalton, average temperatures in parts of Europe fell by 2C.
However, it is also possible that the new solar energy slump could be as deep as the ‘Maunder minimum’ (after astronomer Edward Maunder), between 1645 and 1715 in the coldest part of the ‘Little Ice Age’ when, as well as the Thames frost fairs, the canals of Holland froze solid."
