There was a study done in Sweden by the Swedish government, every day for 70 years. Every day from 1950 to 2020, they kept track of the daily temperature to see how the average temperature changed over time. They found the temperature changed by 0.000%, no change at all.
Maybe there has been some temperature changes in other countries, but none in Sweden. And Sweden is on the same planet as all the other countries, so if it is Global warming, Sweden should have seen it.
