Wonder what caused the Global Warming trend that

Hardly likely Cecil. The amount of CO2 in the atmosphere has varied
quite a bit over time. Lot's of sources of it, and lots of sources of
other greenhouse gases.

Certainly the Deccan Traps indicate that volcanic activity likely
had some effect on CO2 atmospheric content. That was quite a bit before
140,00 years ago.

The sun itself undergoes some variability. It is likely that many
things contribute to temperature variations.

Human effects would hardly have made any impact before our
population growth and inadvertant release of greenhouse gases did start
to have that impact.

Let me ask a question of the doubters. Say that a new ice age came
about. Say that Canada and much of the north were starting to freeze
over. In the sothern Hemisphere, the same was happening. All this was
meaning that Humanity was going to loook at a huge die off, as useable
land were to shrink, and the present population became unsupportable.

But perhaps a way out was available. Burning as much carbon based
fuels as possible would possibly raise global temperatures some. Perhaps
land at the fringes would become able to support agriculture again,
instead of being glaciated. Perhaps more humans could be saved.

Would that be okay then? Would it be worth the effort? Or should we
just die off because it was a liberal plot? ;^)
