It starts off badly with "man’s addition to the carbon-dioxide flux in the atmosphere, by fossil-fuel combustion, is essentially irrelevant"

Arguments Condensed:

• Human CO2 is a tiny % of CO2 emissions
• Water vapor is the most powerful greenhouse gas
• The "Arctic Ocean Model" explains warming
• We need the greenhouse effect
• co2 rise is natural
• I am part of a "large minority"

Notes:

• uses the phrase "so-called greenhouse gas". I see this phrase a lot. What does it mean? Are they casting their luck whether co2 is a greenhouse gas? Perhaps they are suggesting the possibility that "greenhouse gases" don't even exist. What is up with this frequently used phrase?
• This author actually puts forward their own explaination for the warming: "And behind that again is the alternative warming concept, most generally known as the Arctic Ocean Model, which is considered by many to be the real driver for the temperature oscillations and has been for the last million years or so.".

Arguments Condensed:

• Warm records are meaningless because the records are too short
• Can't see global warming in last 150 years of PDO record...
• PDO unreleated to global warming

Notes:

• He says: "The unprecedented great Pacific climate shift of the late 1970s linked to global warming was, in fact, precedented and unrelated to global warming". I guess he's therfore ruling out the PDO as an explaination for the recent (post 70s) warming?

edit: the correct spelling is Titchmarsh I believe.

Arguments condensed:

• Climate's changed before
• Why no warming during the industrial revolution?
• We’ll lose some species, but we’ll gain others.
• Accepts manmade global warming and acting on it.

Notes:

• In the news article he says: "Why didn’t we have global warming during the Industrial Revolution? In those days you couldn’t have seen across the street for all the carbon emissions and the crap coming out of the chimneys."
• Also says: "I’m sure we are contributing to global warming, and we must do all we can to reduce that"
