As for global warming, it leaves me cold (ha ha) on two counts. One is the debatable evidence for the phenomenon itself. The other is the debatable evidence that, if global warming is real, it's necessarily bad.
Or what the cause is.
More pressing issues concern air, soil, and water quality. I am hugely disappointed that environmental groups focus so much on global warning when resource contamination continues to be such a huge issue. Who cares if greenhouse gasses will get you in 200 years if industrial or mining contaminants are poisoning you now?
Same goes for energy production. Coal and gas plants generate enormous amounts of toxins compared to modern nuclear facilities. Even better, modern building techniques (such as sub ground reaction areas) mitigate most of the commonly feared risk (such as meltdown or explosion).
And Ter, evidence for past cold streaks or even ice ages is not necessarily tied to accepting a given time scale for them. Anyway it's well established that Earth has long-cycle climate changes, even during recorded history.
