You sound like a knowledgeable bloke, but if global warming is hokum, why
does New Scientist tell me it's real? Is this to do with research grants,
like the asteroids heading towards the Earth that the astronomers find
whenever they are trying to get increases in funding?

Global warming is real, but it's a natural phenomenon, not man-made.

Are you saying:

a. The current CO2 levels are a natural phenomonen. For the last
700,000 years, CO2 concentration has varied between 180 and 300ppm. In
the last 100 years, it has risen from 280 to nearly 400 ppm.

or,
b. That increased CO2 levels have no impact on climate, and that
something else causes CO2 levels and temperatures to correlate.
