The climate system is more complex and more chaotic than the narrative allows, and not at all sensitive to CO2.

Record Cold Sweeps Parts Of The U.S.

A sharp Canadian air mass has spilled into the United States, setting July cold records — notably in the Upper Midwest.

In Minnesota, the Twin Cities logged 52F (11C) on Thursday, matching the July 17 record set in 1976. With International Falls dropping to 42F (6C), tying a record that stood since 1918.

To the northwest, Grand Forks logged its coldest July 17 in over 50 years, with Grand Forks International Airport seeing 41F (5C), breaking the old record of 44F (7C) set in 1971. Even more impressively, Fargo matched its 1885 record with a low of 43F (6C).

While in South Dakota, Watertown’s hottest day so far this July has been just 83F (28.3F), marking the coolest July maximum since they began keeping records in 1893.

The cold hasn't been confined to the north.

For example, at San Francisco International Airport, an average maximum of just 67.6 F (19.8C) was recorded from June 1 to July 15—the coldest such period since 1965. Cities like Oakland, Santa Rosa, and San Jose have held between 3–6F below normal during the same period, making for the coldest start to summer on record in many regions.
