Nobody has proven, or disproven, anything to do with climate change. All that anybody can do is propose a hypothesis, make predictions based upon that hypothesis and sit back to see whether the predictions come true. So far, models based upon the hypothesis of anthropogenic global warming have failed to come anywhere near predicting what happens in real life.
So we keep being told but there is no trace of it in the scientific literature of the time.
It must have been a lot more than 15 years ago if it was Rutherford labs, they were merged with the Appleton Laboratory in the early 80s to form RAL. The vast majority of research at RAL has absolutely noting to do with global warming but receives funding none the less.
No, you didn't understand it, that was what the watermelons told you.
It might if it were to happen.
It is also nothing like the Maunder minimum yet. It would need to fall by another factor of two or so. The present sunspot cycle 24 is about as strong as typical cycles 12-16 which cover from 1880 through 1930.
Sunspot cycles 18,19,21 and 22 were unusually strong compared to the historical record which goes back to 1750. The lower solar maximum activity is mainly to frustrate owners of new H-alpha telescopes.
It is ironic that this claim should come hot on the heals of a CME that made auroras visible from the South of England - hardly a "quiet" sun.
The Express only exists to promote wilful ignorance in its readers.
Unfortunately most Americans (and Express readers) will not.
The effect of higher global temperatures is subtle. The main one that you can be fairly sure of is that a warmer atmosphere will hold more water vapour and as such be capable of supporting more powerful storms.
The UK could end up with a climate more typical of its high latitude if the Atlanic conveyor (aka Gulf Stream) stalls or slows down. Global warming means that the global *average* rises but not everywhere is affected equally. A few unlucky places may actually get colder.
It is the polyatomics mainly CO2, H2O and CH4 that trap heat. Diatomics like O2 and N2 play no part as greenhouse gasses they are transparent.
The increase of CO2 has been measured now for many decades by the late Dr Keeling at Scripps. You can even see the effect of diffusion from the heavily industrialised north down to the south pole.
Dubya Bush had a damn good try at closing them down but in the end was forced to give Dr Keeling the highest US science award in 2002.
Keeling's son went on to perfect a precise atomic ratio instrument O2:N2 which can measure the corresponding decrease in the oxygen concentration (which requires nearly 5 sig fig measurements to see).
The record is now about 25 years long continuous monitoring.
It will take a few more direct storm hits on major US cities or their grain belt becoming a dust bowl before Americans take AGW seriously.
Churchill famously said "you can always rely on the Americans to do the right thing - but only after they have tried everything else". (paraphrasing)
Sadly despite rising levels of CO2, global temperatures are not really rising at an alarming rate, if at all, and as for super storms, the last decade has been amongst the quietest on record.
Reality will always win in the end. The question is, which reality will it be?
Right now the reality seems to be that without positive feedback, for which not only is there no evidence whatsoever, but rather the reverse is the case, the effect of CO2 increase on global climate will be so insignificant it will be dwarfed by other effects.
The panic in fact was simply a coincidence between the need for a theory to justify state control of the energy industry, with a random period of fairly unspectacular warming in the late 20th century...
