But will cutting CO2 emissions actually be harmful?
Maybe so, scientists in Germany have been studying the effects of CO2 on plants. Much to the environmentalists' chagrin, increased CO2 actually INCREASES crop yields. Barley, beet and wheat output actually increased 10% when those crops were subjected to increases in the greenhouse gas. (See the Breitbart story here.)
So, do we really want to reduce CO2?
In all seriousness, the global warming crowd is all about hype and hysteria. They can't predict future but there is attention and money in a steady drumbeat of doom. Take what any of them say with a grain of salt.
