It's science not politics. We've been pumping CO2 into the atmosphere since the mid 1800s which has finally got to the point of tipping the climate out of equilibrium. Think how much pollution we've pumped into the atmosphere of the last 175 years or so and it's finally having a warming effect that will get warmer faster as it goes. There's lots of frozen methane in the melting permafrost ready to make it worse. What do you want to spend money on, trying to reduce greenhouse gasses or relocating all of the world's coastal cities to higher ground or trying to build sea walls around them? (or all 3?) Take your pick. Both are daunting tasks but folks now are concentrating on trying to fix the atmosphere (while planning for the others) which seems to me to be much cheaper, just reduce carbon emissions. It's a big long-term project, get on board. Amazingly enough Trump likes to lie about climate change. On the campaign trail, he said sea level rise is 1/8" in 400 years when it's 1/8"/year. That's a big lie but he doesn't tell little ones. Claim: “The ocean’s going to rise one-eighth of an inch over the next 400 years … and you’ll have more oceanfront property, right?” Surely there's a special place in hell for leaders who lie about important sh*t like that.
