The Cooling Of The Debate

Some selected paragraphs from here. No particular context ...

The link between solar cycle length and decadal global temperature changes is obvious throughout all the weather records. It's not strictly a sunspot issue, it just happens that the longer the solar cycle is the less intense is the sunspot activity and presumably the overall heat output ( not necessarily the same as what we artificially term Total Solar Irradiance) during the cycle.

Short fast cycles with many sunspots result in warming. Long slow cycles with fewer sunspots result in cooling.

The greenhouse effect, as a whole, may smooth out rises and falls in temperature from other causes but is not itself the determining factor for global temperature. If the heat from the sun declines the global temperature will fall with or without any greenhouse effect and if the heat from the sun increases the global temperature will, of course, rise. The greenhouse effect does not create new heat. All it does is increase the residence time of heat in the atmosphere.

So far, the current solar cycle (number 23) is into the 12th year in length and may go to the full 13.6 years for known astronomical reasons. The very fact that it is longer than the previous two cycles suggests we are getting less solar energy already and, surprise, surprise, it is now being accepted by alarmists that warming has stalled and the planet may be cooling for the next 10 years at least. All they can do now is bleat that the underlying man made warming signal is still there but they cannot prove that to be the case nor can they demonstrate the scale of it in relation to natural causes.

That is why, despite hugely different environmental conditions in the past, including far higher CO2 levels, there has never been a ‘tipping’ point that changed the pattern of glaciations and interglacials that have occurred with clockwork precision based on astronomical movements throughout the historical record.

Nor need we fear any man made addition to solar warming because the proportion of the warming which we would be responsible for would be insignificant against the scale of the solar induced portion.

In any event, since cooling is worse than warming for humanity and most life on the planet, our production of CO2, however large in our puny terms, would be wholly beneficial for life on Earth.

Making policy decisions on the basis of current knowledge (and in the light of recent observations) would be wholly irresponsible. Using food for biofuel production should be a crime and yet that is the single most influential result of global warming alarmism so far. Just the start of the potentially murderous cycle of bad policy decisions that are likely to be based on a false premise.

Some additional reading from Stephen Wilde here and here. The alarmist community needs to offer more proof and less unverified computer modelling.

Interesting educational reading.
