Global warming discussion

[Yarrah]

Autumn's done now. 30 november is the meteorological end of autumn, so it's a fair comparison.

[P.K.]

As Yarrah says its winter in 4 hours. The monthly average was still 7.9C to yesterday and another warm night last night so it has definitely gone and by rather a lot.

Regarding the idea of stopping sun beams reaching earth with nukes or sulfid,
the carbon dioxyd not only warms the planet it sours the oceans.

Corals and other marine organisms building complex calcium carbonate skeletal structures
will suffer when the oceans become more acidic.

Oceans have already absorbed approximately 118 billion metric tons of
carbon between 1800 and 1994 produced by burning oil and coal.

It's important, when assessing temperature patterns, to remember that local temperature records do not, of themselves, have anything to do with global averages. After all, they could be indicative of only an increase in local variability -- maybe there will be some coming cold records that, when averaged with the warm ones, will cancel things out.

Also, there's an El Niño in progress, and anything happening just now shouldn't be compared to the "normal" climatology. If there are high (or low) temperature records being set anywhere, the next step is to compare those temperatures with re-calculated records that use data only from other El Niño years.

This is not to suggest that global warming signatures don't manifest themselves in local temperature extremes; they do and will. But one, or even several, record highs do not global warming make. HPH
