The three temperature records I trust the most - all of them American - all show the same anomaly.
(1) UAH (University of Alabama at Huntsville) Global Satellite Temperature clearly shows the anomaly. The two climate scientists in charge of the UAH since 1979 have never been political and have been accused multiple times of being biased Conservatives.
(2) US Climate Reference Network is the most pristine and most accurate temperature gathering network in the world. It shows a large warming anomaly in the Lower 48 United States for the last 12 months.
(3) Temperature.Global - a computer program that has been collecting 50,000 to 70,000 global land station temps every hour for almost 10 years. Compared against a 30 year average, the global average temp declined, or was unchanged, for SEVEN straight years. Fourteen months ago, that changed. For the first eight months, there were modest increases in the anomaly. In the last six months, there have been significant increases in the temperature anomaly.
Bottom Line - there has been a valid increase in the global (and USA-48) temperature anomaly during the last year.
My own guess would be the Tonga undersea volcano explosion that injected billions of tons of water vapor (the most important Green House Gas) into the atmosphere.
Also, the Covid economic slow down, creating cleaner land mass air, which increases radiant sun shine onto planet Earth.
Also, cleaner ocean air, because of new ship fuel restrictions, which increases radiant sun shine on the ocean.
Perhaps all we need do is look to God. Since this earth is as close to Hell as any believer will ever get, and it is likewise as close to Heaven as any non believer will ever get, maybe the real cause of the heat is the earth progressing towards the end times faster and faster. One thing for sure, if the God haters are this alarmed about a little warming, they are going to really crap their pants, eventually.
