Majia here: It is my very strong conviction that climate change is real (although, I believe that the carbon market and climate derivatives are a major scam and are infused with fraud at every level).
[One of my publications makes this argument in the last section of the essay http://www.mediatropes.com/index.php/Mediatropes/article/view/15747 ]
For me, the science seems pretty clear that earth has entered into a period of climate disequilibrium. The range of factors that have contributed to this shift no doubt include human contributions, increased solar activity, and countless other forces of nature.
Significant for humans are the implications for food production.
Minor increases in temperature can have major impacts on plants' productivity.
Gardening in the summer in Arizona where I live demonstrates this point. Tomato plants, for example, produce fruit in the spring and the fall, but not in the summer when temperatures soar. A short spring or fall means no fruit production at all.
Another example: We won't have any watermelon this year because we planted the vines too late and they didn't have a chance to set fruit before the temperatures spiked.
Increasing temperatures in some regions, widespread drought in others, and torrential rains in still other locales have ominous implications for agriculture.
Here is an article documenting yet more support for climate models that predict future chaos in food production:
Climate models that predict more droughts win further scientific support By Hristio Boytchev, Published: August 13The Washington Post
[Excerpted] The United States will suffer a series of severe droughts in the next two decades, according to a new study published in the journal Nature Climate Change. Moreover, global warming will play an increasingly important role in their abundance and severity, claims Aiguo Dai, the study’s author.
His findings bolster conclusions from climate models used by researchers around the globe that have predicted severe and widespread droughts in coming decades over many land areas. Those models had been questioned because they did not fully reflect actual drought patterns when they were applied to conditions in the past. However, using a statistical method with data about sea surface temperatures, Dai, a climate researcher at the federally funded National Center for Atmospheric Research, found that the model accurately portrayed historic climate events....
