Just what was the high temperature in Rome on March 15 in 44 BC? How about the morning low temperature in Hastings on October 14, 1066? Just who was monitoring temperatures on the North American continent in the year 1250?How cold was the average temperature during the last Ice Age? Yet we are told last year was the hottest year in millennia. The only reliable surface temperatures for the planet are from satellite data collected only in the last 50 years and without manipulating the numbers there is no warming trend and quite contrary the trend is cooler not warmer.
With temperatures plunging tonight in the Midwest to minus teens and below and typical of these polar vortices winds are relatively calm, how would windmills generate enough electricity to heat homes? The last month has had scant few days of sunlight nixing any serious contribution from solar cell farms to our electric needs. I can only hope that Greta Thunberg is freezing in her bed tonight.

-————For temperature since about 1850, scientists can refer to the “instrumental record.” This is a world wide record based on standardized thermometer readings from thousands of meteorological stations around the world.
Because there are now thousands of weather stations, the uncertainty in temperature measurements is now much lower than before 1850. But that doesn’t mean it is simple to figure out the average world temperature! It turns out you can’t just take a regular average — instead, you need to account for the unevenness of the weather stations (lots in the US, few in Greenland or Africa, for example), urban heat island effects, and lots of other possible quirks.—————
The article goes on about how we can use ice cores and tree rings to extrapolate temperatures BUT... That is not accurate, rather only down to a plus or minus a couple of degrees Fahrenheit.
So we’ve only had decent temperature measurements since 1850, and not all at once, but over a long period of time (the best records starting in Western Europe and the USA), gradually only reaching remote locations in the past 70 years or so (after WWII). Satellite surface temperatures have been gathered since the late 1960s but the accuracy is not as great as the carefully placed modern thermometer at a documented earth station.
The warming of the past several decades has been about 1-2 degrees Celsius. That’s it. And they say it might go up as high as 5 degrees—where the biggest doom and gloom stories exist. Yet they’re not sure. Some computer models say global temperatures could get this high.
Models that depend on accurate and massive amounts of data...
But, as you say, what was the precise temperature of a location more than 150 years ago? On a planet 4 billion years old?
Greta Thunberg and the other globulist loving scum are hoping it is YOU and YOUR FAMILY that are freezing to death in your bed tonight.
The Chinese love that we are destroying our electric grid all the while they are loading more coal plants than Al Gore would ever approve of.
The Chinese destroy our electrical grid with China Joe and our military with the VAXXXXXXINE mandates. It appears that Joe is doing EVERYTHING the Chinese would want a POTUS to do to hurt the US. If I didn't know better, I would say that ALL of the Joe's bribe money was effectively spent.
We know Joe didn't get any of the $millions from Hunter's businesses because he said so. If you can't believe Joe then who can you believe?
