It’ll be the end of the world unless we give trillions of dollars to turd world crap holes!
So is this raw data, or has it been “adjusted” for calibration errors, precision & accuracy changes in sensors, land use, population changes. ... and whatever other factors they have to apply to get the results they need to support their agenda.
The receding glaciation around Greenland is the result of warm water not ingressing into the temperature differentiations in the gradient underlying the movement of ocean waters over a vast surface of the ocean surrounding Greenland that results in the lack of distinguishing the two gradients that causes temperatures to be unevenly distributed, resulting in the defying of the physical properties of cold water and hot water caused by a lack of salinity brought on by large amounts of fresh water invading the area because of global warming heat meeting cold and not mixing adequately to cause amelioration of the lack of circulation of warm water over cold. See? Ya know?
In other words, George Bush did it.
IMHO
I’m betting if you add the top quarter and the bottom quarter, (that don’t have temperatures documented) you may have colder temperature that average out the “hotter” temperatures around the belt of the planet.
Remember, the presented temperatures are not real temperatures but the temperatures adjusted to meet the agenda of the global warming pseudo-scientist.
Looks like - from that chart - the Arctic, Greenland, and the Antarctic (among others) do not count toward world temperature. If that is correct, then, of course, the world would be getting warmer ...
