Are we likely to see rising sea-levels? Not in our lifetimes or hose of our grandchildren. It is not even clear that sea-levels have risen at all. As so often in this domain, there is conflicting evidence. The melting of polar or sea ice has no direct effect.

Whatever politicians, activists and manipulators propose, it is the phlegmatic, indifferent, ingrained electorate which disposes.

How reliable are the computer [climate] models on which possible future climates are based? Not very. All will agree that the task of modeling climate is vast, because of the estimates that have to be made and the rubbery quality of much of the data.

Why is there such insistence that AGW has occurred and needs drastic solutions? This is a puzzle, but my short answer is that the IPCC has been built on the AGW proposition and of course keeps plugging it, whatever the data say. The IPCC has considerable clout. Most people shy off inspecting the evidence because it looks like science and must therefore be hard. The media have been captured by AGW (it makes for great stories), the environmental movement and the Greens love it, and business is reluctant to get involved.

Is the warming unprecedented? Probably not. There is abundant historical and proxy evidence for both hotter and cooler periods in human history. Is it our fault? Again, maybe. The correlation of increasing warmth with increasing carbon dioxide concentrations is particularly weak; that with solar energy and with ocean movements is much stronger.
