measuring a mean global temperature is next to impossible even with today’s technology, let alone relying on data recorded decades or centuries ago, or extrapolating data via ice core and soil samples.
I’m still waiting for the report that proves that global warming is a bad thing for North Americans (even if it’s worse than .17 degrees per decade). People who have a choice have never willingly moved to colder climates, and we can’t even imagine the economic benefits of a Northwest passage.
I agree.
Also, trying to correlate human activity with global change is pretty near impossible.
It is more politically driven than scientifically driven.
Libs like Gore and Streisand who like their private jets and homes with large thermal footprints, agonize over the unwashed masses alleged abuses of natural resources.
As is the case with liberal politics its quite hypocritical and class driven.
