As Joe Biden considers a ludicrous "national climate emergency" and the hysterical climate-porn doomers are getting even more hysterical about a summer heat wave, the most recent NOAA climate data show the world cooling since the end of December 2014 (NOAA's temperature anomalies chart).
If Joe Biden and Democrats think they can control heat waves by reducing CO2 emissions, they might first check the actual empirical evidence as to the possible efficacy of that.
For example, the correlation of global temperature anomalies and atmospheric CO2 levels is a negative 0.20 (yes, a -0.20 correlation) over the 90 months since December 2014.
Essentially, per NOAA science, imbecilic politicians need to finally realize there is no magical CO2 control knob that bureaucrats can twist and turn to produce desired short and intermediate-term climate and temperature results. Seasonal weather outcomes are NOT controlled by CO2.
Note: More specifically, regarding the current cooling trend, it actually started in April 2014 per NOAA's global (land & ocean) monthly dataset.
