The Earth in the past has gone through large weather cyclical changes. Co2 from Man had NOTHING to do with it. They are growing about 2500 acres of crops in Greenland as the present time.
In the estimated years of 950 - 1250 Crops were also grown in Greenland by Vikings.
That was followed in 1500 - 1700 by the "Little Ice Age"
About 300 years separate the periods.
Up until 1980 these same Scientists were predicting an ICE AGE.
Perhaps some of you forgot that Europe had some of the Coldest Winters in over a hundred years 2-3 years ago.
There is data that suggests we could plunge in an ICE AGE similar to the one 10,000 years ago.
With the additional increase in rainfall - according to some Scientists all it would take to pricipetate it woud be a large Volcanic eruption that blew enough ash into the air to take a year to all clear out. That would be enough of a trigger for Snow - ten feet in Texas and more North of that.
If I was looking for a culprit - for CO2 I would look at deforestation as the Cause. Plants clean the CO2 out of the air.
AFrica and South America have had about half of the land deforested for crops and lumber.
Just think about how much area that one tree has with 50,000 leaves working to clean the air of CO2. Cut a a couple of million miles of trees down and you eliminate a lot of CO2 removal.
Again the Stats on mans contribution for CO2 is 3% not 10% - 90%.
I have never said and will agree we have had some exceptional weather. I just don't believe it is caused by man.
As far as high temperatures - today we have the ability to report every minor change in temperature and snowfall. We had hot periods 50 years ago. I lived in Chicago and we had 102 and 103 temperatures - higher than any recorded in the last 20 years.
