Carbon emissions are a scam.

Co2 increases come after temperature increases in every core sample ever taken.

Pollution is a real problem, but isn't carbon isnt the problem.

Desertification isn't caused by climate change. It's mostly caused by poor land and animal management, and the man-made interferences to the water table and natural reservoirs.

This is a map of areas ag risk of human induced desertification: https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/use/?cid=nrcs142p2_054004

If anyone actually wanted to solve any problems related to climate change, and make the biggest tangible impact, they start with planting trees and plants in these areas.

If you look around you can find more and better examples, but you can get the idea here: https://www.thesurvivalgardener.com/establishing-high-desert-food-forest/

Even the saharan desert is often theorized to be created, or at least contributed to by humans. https://www.dailymail.co.uk/sciencetech/article-4315796/How-humans-created-Sahara-desert-8-000-years-ago.html

Again, there's better sources out there if you're interested.

Geoff Lawton is another guy worth looking up that has restored a lot of farmland.

A video called something like 'how sheep will save the world' is another good one about animal grazing and land restoration.

~'How wolves saved Yellowstone' is another on how reintroducing apex predators saved Yellowstone.
