Note that Hamilton referred to climate change and Howlett focusses on
global warming. I think we need to avoid this, since global warming is
the most controversial and difficult to prove aspects of climate

rise, melting glaciers, and the ecological impacts of higher CO2
(which affects plant communities). These are demonstrable effects and
have huge impacts.

Difficult to prove to whom, Bill. Not scientists, and certainly not
scientists who have studied the situation. But, I am sure it is
appropriate for each person to discuss what he finds it proper to
discuss, so long as it is science.
