There is ZERO evidence that Globull warming even exists.
I was talking historically. Certainly the Earth has undergone massive temperature swings throughout its long history. The heat spikes usually are correlated to periods of intense sunspot activity, as the low temp spikes are correlated to low levels of solar activity, like we’ve been having of late. There weren’t ANY sunspots at all during a 70-year period known as the “Little Ice Age”.
