I'm old enough to remember when the scaremongering was about a new ice age and we were all going to freeze in the dark. Then the hysteria was about the loss of the ozone layer so the sun was going to radiate us all to death. Then the scaremongering was about global warming which was going to make the oceans die and the earth uninhabitable by 1990. Then some areas started cooling, so the scaremongering became about climate change.
The US gov't doesn't fund scientists unless they agree with the current orthodoxy, and gov't funding is vital to pretty much all scientific research in the US, so they agree. That's not science, that's economic self-interest 'cause scientists need to eat, too. Then the media dutifully hypes whatever the gov't scientists have said about climate change to ludicrous levels for the clicks.
Trees, in fact all plants, are CO2 sinks. Dh and I have planted thousands of trees on our various properties over the years. Do your part, plant some trees and stop worrying. It will all be okay.
