> 1.5°C consistent: there are a range of emissions pathways that would be compatible with limiting average warming to 1.5°C by 2100. However, all would require a very urgent and rapid reduction in global greenhouse gas emissions.

Is this polite data analyst-speak for "We're fucked"?

It's polite data analyst speak for, "We need immediate and globally-coordinated _radical_ action" (action being the key term) Edit: We're not fucked yet. Apotheosis of hope.

I'd say at this point, "radical" is the key term here.

Seeing as how the 1.5C pathways require global emissions to go zero of negative within our lifetimes, yes: https://ourworldindata.org/uploads/2018/04/Greenhouse-gas-em....

Pragmatically its more a return to old-style living in many ways but will seem radical to groups addicted to modern lifestyles.

It is always interesting to see graphs like this, I am curious how much something like a new green deal would move the 2100 temperature line. A common argument against it is that everything depends on China and India. I don't suspect this is true. The USA is one of the highest per capita emitters, it doesn't seem right that we would get to live like that while we take away resources from these other countries who are not as capable of switching over. At least we should get to a point where we all have equal per capita emitters, preferably we should be investing in the technology that would allow them to never have to use carbon-emitting technologies and even potentially profit off them.

What I don't understand about this is, that we were flat for about three years, and then we went up a little bit. This to me signals that we are close to if not at peak emissions and we should be able to start seeing the downturn at any time. But the chart you are showing has emissions increasing for the next 20 years. Am I oversimplifying or being naive?

the people pushing the green new deal are doomsday Sayers predicting "crisis" in 12 years. they are more religious than some religious people about their science.

however their 6000 scientists don't appear to look at satellite imagery, or choose not to: "The world is literally a greener place than it was 20 years ago, and data from NASA satellites has revealed a counterintuitive source for much of this new foliage: China and India." source: https://www.nasa.gov/feature/ames/human-activity-in-china-an...
