1) What are the benefits of global warming, according to the author?
Governments are benefiting from it financially, which is allowing people to have the necessary precautions for storms, drought, and disease.
2) How will increasing wealth enable us to adapt to climate change in the future?
"Global warming has so far cut heating bills more than it has raised cooling bills. If it resumes after its current 17-year hiatus, and if the energy efficiency of our homes improves, then at some point the cost of cooling probably will exceed the cost of heating — probably from about 2035, Prof Tol estimates."
3) Why should we care if climate change has caused a 1.4% increase in global economic output?
Because For some people, this means the difference between survival and starvation.
4) Is it possible to compare the costs and benefits of global warming? If so, what does this tell us about what policies we should make? If not, what does this tell us about the policies we should make?
I don't think it's really possible to completely lay our the overall costs and benefits of global warming.
