In the ever changing climate on Earth:
(1) The causes of past warming and cooling are still guesses, and
(2) The future climate is impossible to predict.
Meanwhile, we're lucky to be living in the best climate this planet has ever had for humans and their pets.
Even better -- the climate has been improving for hundreds of years!
The climate is also getting better for the "C3" plants used for food by humans and farm animals, but is far from optimum for those important plants.
Based on thousands of scientific studies, "C3" plants prefer 800 to 1,200 ppm carbon dioxide (CO2) in the air, compared with 400 parts per million in the air today.
The good news:
CO2 in the atmosphere has been growing 2 ppm per year.
The bad news:
At that rate, it will take 200 to 400 years to fully satisfy the CO2 hunger of C3 plants!
The joy from living in a wonderful, and improving, climate is partially ruined by leftists.
Leftists are demonizing very beneficial CO2 plant food, which is harmless, for selfish political and financial gains.
We all know big government leftists alway want more political power.
It's easier to increase political power when there is a "crisis" to scare people.
Clever politicians step forward and claim only they can end the "crisis".
The "crisis" can be real (such as the deep 2007 recession) ... or fake (such as the false claim that man made CO2 will cause a runaway global warming catastrophe 100 years in the future).
After people have been scared by a fake CO2 "carbon emissions crisis", leftists' claimed their government needed more power to fight the "crisis".
Not because the leftists were greedy for power, they claimed, but for a noble cause -- 'to save the Earth for the children and grandchildren' (try not to laugh at that fairy tale!).
Telling the truth is not something that leftists do well.
The truth is that CO2 is a harmless, airborne plant food -- the staff of life on our planet -- not a satanic gas that will eventually end all life on Earth.
The truth is that the Earth needs much more CO2 in the air to increase the food supply for humans and farm animals.
How do I know that leftists really don't care about saving the Earth?
Answer:
Because they completely ignore serious air, land and water pollution in China, India and other parts of Asia.
That Asian pollution is a real problem.
Asian pollution is real and here now ... completely unlike the "runaway global warming" fantasy -- a wild guess prediction of a "crisis" allegedly coming 100 years in the future ... that will never come ... because our planet has had higher levels of CO2 than today for almost all of our 4.5 billion year history ... and there was never any runaway warming in the past (if there was runaway warming anytime in the past, none of us would be here today!)
