Prepare.
The cold times are returning, in line with historically low solar activity.
The jet stream is weakening, diverting brutal polar cold to the lower-latitudes: "
So what was the actual data for the first quarter of 2020? Did this climate chabge denial website get it right? Of course not.
Monthly Temperature: January 2020
The global land and ocean surface temperature for January 2020 was the highest in the 141-year record, with a temperature departure from average of 1.14°C (2.05°F) above the 20th century average. The Northern Hemisphere land and ocean surface temperature departure from average was also highest on record at 1.50°C (2.70°F) above average.
Now to be fair, there was a brief period of cold air in a small area of North America. This is called "weather" not climate change. To look at climate you look at the globe. When it is cold in a few Canadian provinces or one day in Greenland that is not evidence to refute climate change. But one hot day above the Arctic Circle is similarly not evidence to prove that the globe is warming.
It is a bit tiring that the denialists continue to parade sunspot data to "prove" their point because it doesn't support the claim that solar activity is a driving factor. Solar cycles are about 11 years, it goes up then down then begins again. But somehow the global temperatures have only gone in one direction through those 11 years, up.
You know what actually measurable quantity parallels the increase in global temperature. It is not solar activity, it is of course CO2. Man-made CO2 is the major factor in the recent change in CO2 levels.
With the hot temperatures in the formerly frozen tundra there is a very real concern that the methane which has been locked in the frozen soil will now be liberated. Methane is a much more potent greenhouse gas than CO2. Additionally with the decrease in snow/ice cover, the globe will absorb more solar radiation which used to be reflected back into space.
Why should the US lead in solving this problem? Because despite what you hear from some sources, the US leads the world by far in production of greenhouse gases per person. Each American, even with all our high mileage cars and pollution controls produces more climate damaging gas than the citizens of any other country. We are befouling the planet. We have been doing it for decades. We are supposed to be world leaders, "American exceptionalism", a beacon for the world. |
I posted the record Greenland low this year to show the OP that anecdotal climate data means nothing.
