ant,

Good one. But.

I think some scientists are arrogant because they think they know everything about everything about all science, whereas plumbers know about plumbing and mechanics know about mechanics.

I repeat, some scientists.
I think a majority of scientists are constrained by politics involving fear of losing their livelihood.

I would like to make a slight correction to my previous post about Noctiluca.
I mean to say Noctiluca algae cannot swim across the sediment transportation current flowing northwards past the Derwent River

Still no real response to these immutable facts:

a) We need greenhouse gases in the right proportion to survive. CO2 being important in regulating the respiration rate in humans. Earth would be a sphere of ice without greenhouse gases.
b) Since the Industrial Revolution the rate of CO2 and other greenhouse gases have been increasing; for CO2, it has increased from 280 ppm to over 400 ppm currently.
c) Carbon took millions of years to be sequested; we have disposed of fossil fuels (carbon) in huge quantities in a little over a century.
