Everyone can tell that human caused global warming can not possibly be a hoax.
We almost doubled the atmospheric concentration of CO2.
That is an undeniable fact.
And anyone can perform the experiment in miniature, that increased CO2 causes additional heat retention.
Anyone can also look up when the USS Nautilus went under the North Pole in 1957, and there was no open water even though it was summer.
The records show there has never been any open water in the fabled Northwest Passage until 1997, for over a hundred thousand years.

The
Nautilus steamed north through the Bering Strait and did not surface until it reached Point Barrow, Alaska, in the Beaufort Sea, though it did send its periscope up once off the Diomedes Islands, between Alaska and Siberia, to check for radar bearings. On August 1, the submarine left the north coast of Alaska and dove under the Arctic ice cap.
The submarine traveled at a depth of about 500 feet, and the ice cap above varied in thickness from 10 to 50 feet, with the midnight sun of the Arctic shining in varying degrees through the blue ice. At 11:15 p.m. EDT on August 3, 1958, Commander Anderson announced to his crew: “For the world, our country, and the Navy—the North Pole.” The
Nautilus passed under the geographic North Pole without pausing. The submarine next surfaced in the Greenland Sea between Spitzbergen and Greenland on August 5. Two days later, it ended its historic journey at Iceland. For the command during the historic journey, President
Dwight D. Eisenhower decorated Anderson with the Legion of Merit.

The Northwest Passage is now constant and proves an absolute change from the norm for thousands of year.
