Been studying this since 1959. CONCLUSION, humans have no effect on global climate but can effect local climate quite a bit on the small scale. CO2 from humanity has NO EFFECT on global climate. Sea level changes are utterly managable and are NOT a problem , much less a crisis. Over the next 2000 years we are more likely to lapse intto a new 100,000 year period of ice age than a tropical earth. Anthropogenic CO2 has no measurable effect on climate, hell, "termitepogenic" CO2 exceeds HUMAN BY A SIGNIFICANT AMOUNT!
The current hysteria is a witch hunt that needs to be stopped right now.
