It could be climate change.
It is NOT MAN made climate change.
Last Ice age was NOT man made climate change.
The Global warming which followed and melted 4 mile thick ice glaciers on top of Chicagoland was NOT man made either.
Conclusion: Climate change began 5,000,000,000 years ago.
Man could become extinct in a few million years. Climate change will go on for 5 Billion years after man becomes extinct.
And all the uninhabited planets in all the galaxies throughout the known universe never, ever have climate change. Right?
There are theories, but very ill-supported by anything that resembles the careful science we once knew and appreciated, that adding CO2 to our air would bump the temperature way up.
One person noted that to the extent the globe warms for various reasons, its poles warm more than its equator does. The difference between the temperatures of the poles and equator drives the storms. Therefore this kind of “global warming” should mean fewer and weaker storms. We will get fewer Irma’s, not more. The problem here is that all this global warming is down in the noise and might even be exaggerated by measurement factors.
