we can get into that once you admit we are, in fact, a contributor.@oneeyedundertaker so you were not here when CO argued our measurements were off, too many stations in heat islands and unreliable satellite data were used in many threads
As to the old data being wrong, there were some outliers that are used to ridicule. But most projections were in the ballpark:
As to human involvement, any explanation has to account for the troposphere warming and the stratosphere cooling. In other words, heat is coming into the system but isn't reaching the stratosphere when it radiates out. Things like increased solar output, which we measure and know isn't the issue, would cause warming in the stratosphere too. But it is cooling. So any alternative thesis has to explain why the heat radiating off of earth isn't reaching the stratosphere.
The best answer is greenhouse gasses. Much of the heat radiating off is being grabbed by these gasses. We can run experiments on CO2 and see if radiated heat gets trapped by it. So we know they grab onto heat. Now, I fully acknowledge there could be a different theory that is right, just as Einstein's theory of relativity could be replaced by a better theory. But at the moment, based on what we know, the current theory fits.
So we don’t know. It is a great way to virtue signal though.
edit: “So any alternative thesis has to explain why the heat radiating off of earth isn't reaching the stratosphere.”
This statement is ridiculous….
”The best answer” - “guess” is the correct word to use here…
Jesus Christ. You don't even need to be a scientist to know that humans do things that contribute to climate change. We burn things. We power things. We drive things. All things which create heat. That heat goes into the atmosphere. The atmosphere gets warmer. We also create byproducts from all the things we do, and some of those byproducts (like CO2 and H2O) are known greenhouse gasses that help contribute to warming. CO2 helps the planet warm. Period. Naturally released, artificially released, it doesn't matter. We know for a fact that it increases temperatures, and we know for fact that at least some of that CO2 is coming from human activity.
So, yes, it is an incontrovertible truth that human activity contributes to climate change.
The same can be said for every time you exhale, fart, put up “green” solar panels, etc. The question “how much” matters.
How much does matter. But we are not "guessing" we are a factor. We know we are a factor.
1 degree or .000001 degrees?
Of course, my contention for the entire thread has been how much & is it enough to matter.

Pretty crazy how resource rich his country is. Seems like every month some rancher is finding 200 years of oil in West Texas or some guys finds 300 years of lithium in his Appalachian backyard.
Only reason we would ever face resource scarcity is if we overregulate and get in our own way.

Or continue to sell land to the Chinese. We need to eminent domain every piece of land they own…
