Okay now, the 19th Century was supposed to have been a time of much cooler temperatures, due to lower atmospheric co2 levels. The 21st Century has repeatedly been reported to be a co2-fueled sauna of death. Sometimes --- but only sometimes --- the temperatures were honestly reported by the general & generic journalists who market sensationalistic hype. But, that which was very DISHONESTLY reported was the claim that never before had such a temperature or such an amount of rainfall or such a windspeed ever occurred.
The truth is that "it" has all been done before. "It" refers to the "main weather event" being reported by the non-meteorologists who are not articulate in explaining "the science." "It" is the climate activists' "star of the weather show," presented to the viewing public, to create fear and insecurity. "It" is the "excuse" that the climate hysteria faction uses to claim the existence of a new era which now warrants them to takeover all governments and rule mankind through the U.N. New York City then becomes the capitol of the world. This is the mindset of the generation raised on TV, video games, and the cell phone. The Great Outdoors is a concept entirely foreign to the vast majority of them.
Climate is properly defined as the "Prevailing Long-term Weather Trend." Two-week heatwaves --- or three-week heatwaves --- that come in occasional clusters of time throughout a continent, do NOT define the climate. There are the other 49-50 weeks in each year to consider, as well. In 2023, there was record cold and record snow throughout Planet Earth. Drought-ridden dams were refilled as if a fairy godmother visited the American West with a heavy duty wand. Maine even had cryoseisms which were actually reported by media outlets as famous as the Washington Post. However, this will NOT be reported by any Climate Hysteria Network any time soon.
BTW, cryoseisms are frostquakes which happen to occur when already-existing underground water freezes and expands, thereby causing tremors.
At this point, look at the Univ of Maine's Reanalyzer map for the JULY temperature average of the Year 2015. This is the most recent year thus far made available to the public. We can't review anything more recent, unless you want to use the ECMWF data.Below is the reanalyzer map for July of 2015 and also 1845. In 1845, the atmospheric co2 level was 284 parts per million (ppm). In 2015, the co2 level was 401.1 This amounts to a 117 part per million difference between 1845 and 2015.
The Year 1845 was selected for people not natural at math. It's easy to see that 2015 minus 1845 = a 170 year difference. None the less, 1845 was the start of the Great Famine which later became the Irish Potato Famine. Three years later would come Europe's greatest revolution thus far; even greater than the events of July 1789, and only to be exceeded in size and impact by the 1870 revolts. Moreover, the Little Ice Age had recently ended, approximately in 1840 or so. And of course, the Little Ice Age began with the arrival of the Wolf Solar Minimum. This was in 1284 or so. So, 1845 would be a fitting year to use in this example.
In addition, America had a drought between 1856 and 1865. So, those years are slanted in terms of finding a suitable average year. Thus, using 1865 isn't prudent, even though it is an exact 150 year difference from 2015. And yes, the entire American Civil War was fought during a drought.
According to the Al Gore Theory of Climate, it should have been a whole lot hotter in 2015 than it was in 1845. This is because there is 117 ppm more of co2 in the atmosphere today than there was in 1845. Well then, let's look at the reanalysis maps and compare. And remember, for the 19th Century temperature conclusion to be credible, proxy evidence --- even from third party sources --- is needed, to confirm the validity of the map. Thermometer stations were a rare commodity in South America, Africa, and parts of Asia in the 19th Century and prior. Proxy evidence is already explained at this Blue Marble Album.
