I offer this positive diagnosis after a lifetime of study on the issue. Until recently, I was a professor of climate science and Chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology.
But it’s not all good news.
The biggest problem with climate change is not climate change, per se, it’s how we’re dealing with it.
We’re attempting to control the uncontrollable, at great cost, by urgently eliminating fossil fuels. We’ve failed to properly place the risks from climate change in context of other challenges the world is facing.
Climate change has become a convenient scapegoat. As a result, we’re neglecting the real causes of these problems.
There are countless examples, but let me give you just one.
