President Donald Trump calls climate change the “green new scam.”
To counter this misinformation, I encourage reading “The Scientific Guide to Global Warming Skepticism.” It’s available online and provides an excellent summary of the lines of evidence that have led 200 science academies throughout the world, including the U.S. National Academy of Sciences, to conclude that climate change is human-caused.
For example, satellites detect less heat escaping the top of the atmosphere in the wavelengths absorbed by greenhouse gases, and surface observations measure more heat being returned to the earth in those same wavelengths.
Consider that the Israel Academy of Sciences and the Academy of Sciences of the Islamic Republic of Iran agree on this issue.
If one is serious about examining the issue of human-induced climate change, the place to start is understanding why scientists believe it.
Climate change poses great threats, such as more extreme heat waves, sea level rise, and the ravaging of the world’s coral reefs.
Conservatives would be unlikely to tolerate this level of risk with regard to national defense or financial markets.
Prudence dictates that we also hedge against the risk of disastrous climate change.
