re: #1 _RememberTonyC

I have a LOT to learn about global warming/climate change.

I would start here at the the American Institute of Physics:

The Discovery of Global Warming

Start with the introduction essay, and from there you can see there are a number of other pieces to read from the Sun to ocean currents. I’m still working my way through these articles, but it has been invaluable to me in better understanding the science involved.

[Thanks to freetoken and LVQ for turing me on to this great resource.]
