I think there has been a mild warming taking place since 1850. Since 1850, the global temperature, if you could derive such a thing back then, has gone up 1.5 degrees C. That’s it.
Honestly, I don’t why they have such faith in the early numbers; thermometers were not perfect and very few global recording stations were set up—it took decades for those things to happen, and the World Wars meant a lot of data wasn’t collected. I do agree that very accurate instruments and a wide expanse of collection points are now available, but the only real reason they start at 1850 is because it was really cold then and steam powered industrialization was becoming common.
1.5 degrees C, globally, over 150 years? Very mild, a scientist would conclude.
The hoax is in the “projected numbers”. Some computer models show up to 10 degrees C rise by 2100. But that’s just guess work, without adequate data to show how they came with that... They do input data into the model, but since it’s future data, they’ve been putting in excessive numbers that—so far—haven’t panned out.
Those same models, run in 2005, for example, say we should be at 3.5 degrees C rise by now, but we’re not. They don’t explain very well. They say, for example, “unforeseen ocean swelling from the far depths”, or some other nonsense that SHOULD have been in their model. And guess what else?
Since the model has already shown itself—and others like it—to be failable, they still go on with it—not adjusting new data or information, but just the same erroneous forecasting as if that expected 3.5 rise was not false!
Talk about a hoax! It’s all in the model!
Pretty sure the alternative might be harder on humans. Again.
