So, do we have a problem with a global warming? Pretty much everyone agrees that the world has warmed, and 97% of climate scientists agree that humans have caused it. Most of those also agree that it is going to get worse, and we should definitely do something about it.
Then why is it that in the more than 20 years since the UN got together and said we should cut our emissions, global emissions of CO2 have increased by 61% from 1990 (the reference year for the Kyoto Protocol).
Because curbing climate change is not easy, and it is expensive. And as I have mentioned many times in the blog earlier, the impacts are very unequal. For a farmer in Illinois or in Canada, changing their lifestyle or paying for a “greener” world may not make economic sense.
