If the earth’s climate were a person it would be 5ft tall, weigh 600lbs and eat 15,000 calories a day, and the plan to save it would be to have it reduce its food intake to 12,000 calories a day. We are not fixing anything, the earth’s climate would just get fatter a little slower.
"This image should terrify you. It should be on billboards.
As you can see, in either scenario, global emissions must peak and begin declining immediately. For a medium chance to avoid 1.5 degrees, the world has to zero out net carbon emissions by 2050 or so — for a good chance of avoiding 2 degrees, by around 2065.
After that, emissions have to go negative. Humanity has to start burying a lot more carbon than it throws up into the atmosphere. ... Thus far, most demonstration plants of any size attaching [carbon capture] to fossil fuel facilities have been over-budget disasters. What if we can’t rely on it? What if it never pans out?"
Solar, wind and gas for electricity. No more coal. Technology already exists. Side effect: cleaner air.
Electric cars and trucks for transport. Technology already exists. Side effect: cleaner air and better cars.
No more beef. Pork, chicken, insects and plants instead. Technology already exists (has for thousands of years). Side effect: less water use, healthier diets.
Mostly these things would come faster with a broad enough carbon tax, instead they are coming slowly. I'm completely certain that we could do all of the above in 5 years.
At most the above would entail minor inconveniences for the average person. It just takes the political will to place a minor inconvenience on a population whom you hope will still vote for you.
And this is why the future is looking so grim, unless we can somehow convince the population at large to accept this inconvenience.
The public tends to vote for people who decrease inconvenience, and shun those who propose to increase it.
How can we change the minds of millions/billions of people away from that mindset?
It would be as if someone suggested saying a prayer before going to bed would save the world. What's the problem, it's a 2 minute prayer? And yet a large number of people would be up in arms about it.
I understand that you're shouting "Science" before telling people how to live their lives. Hey, maybe it will work. But it's profoundly political and even if they don't articulate it as such that's how people will see it.
And yes, it is political, because the only way we'll be able to counteract climate change is by concerted, collective political effort.
For climate change, the total amount of released carbon is what matters. So far we haven't been able to even get the second derivative to point in the right direction.
