If you’re thinking “well, mostly from nature, especially since the oceans put out 16 times more CO2 than Mankind does, and water vapor is the #1 GHG”, well, um, it seems Grist and the Warmists forgot that part
Here’s a tiny version of a large, information-dense graphic from research consultancy Ecofys:
(WT: I’m giving you the tiny version)
You should click and look at the big version, or better yet get the PDF from Ecofys and zoom in really close, where you can see the sectors further broken down.
Now, if you head over to Grist or click on the PFD link you might notice what is missing: natural sources of GHGs, which are considerably larger than anything Mankind does. But, that would harm the narrative that Mankind is evil (say, I wonder how much GHGs the websites and servers for Grist and Ecofys, as well as the Disqus commenting system Grist uses, put out. And the computers they use. And the electricity to run them.)
No grand conclusions to draw, just something to think on. Every one of these sources can be dialed down, through conservation and efficiency if nothing else, but off the top of my head I’d say the easiest targets for rapid emission reductions, in no particular order, are: 1) stop chopping forests down, 2) zero out emissions from residential and commercial buildings, 3) capture methane everywhere, from agriculture to energy to solid waste, 4) reduce vehicle-miles-traveled with densification and transit, then electrify the hell out of everything else in transportation.
All by Government decree, right? You first, chumps.
Anyway, what do you think? What are the top-line lessons of this graphic?
Well, mostly that Warmists are liars and full of mule fritters, hiding the full measure of GHGs. And that they do not understand science or reality.
