Just from looking at global temperature trends over the past 120 years
or so, I've thought for some time that there is an approximately 30
year sinusoidal trend over the gradual warming trend and it looked to
me like we were on the cusp of a downward trend. There is evidence that
backs this up.
Here
is an article from the National Post of Canada which notes that this
winter has been a really bad one. Some key lines from the article:
"Snow cover over North America and much of Siberia, Mongolia and China is greater than at any time since 1966."
With regards to Arctic sea ice which had supposedly "disappeared", this year it is 10 to 20 cm thicker than last year.
Also,
things might be worse than a small down-turn in temperatures-
supposedly sunspot activity is at a very low ebb. The article states:
"The last time the sun was this inactive, Earth suffered the Little Ice Age that lasted about five centuries and ended in 1850."
I'd say that the only thing we know for sure is that we don't know what is going on with global climate trends.
