This article describes The Physics of the System relative to Global Warming. Even though exact modeling of the climate for past and future average global temperature is enormously complicated, the physics, the facts, and what they mean are not.
One does not have to be a rocket surgeon to understand this. The facts and their implications are not up for negotiation. "Physics does not negotiate! Physics just does."
Let me be clear, this is an existential threat to life on earth. Please, pay attention and stop denying reality. Some against abortion of fetuses say that's "child murder", yet they are quite willing to vote for Trump/Republicans who deny this threat to all life on earth.
In 2001, Ron Suskind wrote in The One Percent Doctrine, Vice-President Dick Cheney announced that if there was "a one percent chance" that a threat was real "we have to treat it as a certainty in terms of our response." Cheney added, "It's not about our analysis, or finding a preponderance of evidence." If "conservatives" believe that about attacking other nations, why do they quibble over whether it's 97% certain that life on earth is threatened by global warming?
Trump/Republicans are a clear and present danger to all life on earth. This is the ultimate in evil.
I will not be around for the most disastrous consequences, so this will not affect me personally. I do not have children, but those who do and don't take this seriously are condemning them to a dystopian future in which billions of humans will die and countless species will go extinct.
