"the cost of doing nothing about it will make the current little economic cuffuffle look like a picnic .... so it is something that must have a very high priority" What is the evidence that doing nothing will have serious economic impacts. Carbon and carbon dioxide are not pollutants: It may surprise some to learn that plants use carbon dioxide to live. So more carbon dioxide leads to more flora, more flora to more fauna etc...... so that life is more sustainable, not less. The relationship between carbon dioxide and atmospheric warming is not linear, but logarithmic. Global temperatures and sea levels have not risen by anywhere near the amount predicted by past models.. The conclusion is that those models are wrong.
Incidently: look at the temperature of Puenta Arenas, the city nearest the South pole. Its temperature is going down, not up.

link please...
Some places will cool regionally while the average temp for the planet is increasing.

As we all have an interest in astronomy, I assume that we all are to a lesser or greater extent interested in what is happening beyond earth's atmosphere. The solar wind, I read the other day, has slowed down and, apparently, this causes more insolation. I don't know the extent of the increased insolation, but it must have some contribution to rises in global temperatures.
The debate about the extent of global warming, whether it has gone beyond what has been observed in the geological record, and to what extent it is man made, and what its economic consequences might be, is not over, no matter what the politicians of green, pink, or watermelon varieties say.
I am suspicious that many who espouse global warming are academics looking to stay in employment: I cannot regard them as disinterested observers, but as people who consume my tax dollar to promote a cause that will cause me financial loss if their advocacy prevails.

no one who has followed the scientific effort to understand what has been is saying solar output fluctuations (ie sunspots) is not effecting the climate cyclically , how ever there are more powerful artifically created climatic forcers (I refer you the IPCC report if you want to know more).
