Funny thing about the Trump refusal to agree to the Paris accord is that it mobilized huge corporations, foreign countries, governors and states, mayors and cities, scientists and the general population to speak up and set up alternative partnerships that won't be hindered by politics. The public outcry has been very strong. My belief has always been that the solar solution would not come from the federal government as they are too bureaucratic, but there are a number of international non-profit organizations fighting climate change. I sense the rate of change may have increased this week. Time will tell.

IMO, Solterra Renewable Technologies has always supported these efforts and you can read how Solterra plans to participate in the solution -

On that page are links to organizations who have roadmaps to mitigate climate change, IEA, IPCC, U.N., MIT, and IRENA. These are long comprehensive reports, written by experts who take the subject seriously.

If I didn't believe in climate change, I sure would not invest in a company trying to change it. That would be hypocritical and continuing to invest in such a company would in effect be giving support to the enemy and wanting to profit from it.
