Climate 99, Cooling trend, virus alarm and climate alarm

Here is the latest global lower tropospheric temperature (LT) anomaly or variance from the 30-years average (1991-2020), drastic cooling at -0.01 C in March 2021.

Is this because of global lockdowns, there is less CO2 emission in the world?
No. On the contrary, global CO2 concentration in the atmosphere continues to go up, global lockdowns have little or zero impact on CO2 level.

And see the big divergence between global temperature projections vs actual.

Now in the fight vs Covid, there are several conflicts between climate alarm and virus alarm.

1. Proposed double mask. Climate alarmism says CO2 is a bad pollutant gas (must be over-regulated over-bureaucratized over-taxed). And we humans exhale CO2. Double mask means the CO2 that people exhale is partly trapped while fresh oxygen is restricted from coming in so people re-inhale that "bad pollutant gas" that they already exhaled. See, 

German Neurologist On Face Masks: ‘Oxygen Deprivation Causes Permanent Neurological Damage’

“The reinhalation of our exhaled air will without a doubt create oxygen deficiency and a flooding of carbon dioxide. We know that the human brain is very sensitive to oxygen deprivation."

2. Huge use of masks, faceshields, hazmats, other PPEs made of plastic and non-reusable materials. Both from hospitals and households. See,

Medical waste in pandemic-hit Philippines: As much as 2 million sacks of rice

Climate alarm says do 3 Rs (reduce, reuse, recycle).
Virus alarm says No to 3 Rs but throw dispose. Use more masks shields, plastics, not less.

3. People mobility. Climate alarm says use more mass transportation, trains buses, avoid cars and save energy. Virus alarm says avoid high density transpo like trains buses, more cars better.

4. Outdoor activities. Climate alarm says do more outdoor work and exercises and use less energy, run on the roads not on treadmills indoors. Virus alarm says avoid outdoors, do more indoor work and exercises, stay home.
