I didn’t know whether to laugh or cry at the Beeb’s latest gaseous emanation regarding global warming.
Now, I am no climate scientist, but I harbor a suspicion that maybe, just maybe, one factor impacting on the Earth’s climate just might be – now, I’m just throwing this out – the sun. I find discussion of the sun’s impact on global weather to be oddly absent from the reams of paper speculating on how minute variations in various gases here on earth may affect climate, rather like speculating on how adjusting the air pressure in your tires a few ounces might affect fuel efficiency without ever considering the, well, fuel you are putting in the tank.
I have noted the occasional article exploring the correlation between temperature variations and solar activity, and so I read this with interest:
Scientists based at the Institute for Astronomy in Zurich used ice cores from Greenland to construct a picture of our star’s activity in the past.
They say that over the last century the number of sunspots rose at the same time that the Earth’s climate became steadily warmer.
However, the scientists made sure that the reigning anti-materialist orthodoxy of those providing their grants was not called into question by these merely scientific observations, scurrying to observe:
This trend is being amplified by gases from fossil fuel burning, they argue.
This latest analysis shows that the Sun has had a considerable influence on the global climate in the past, causing the Earth to warm or chill, and that mankind is amplifying the Sun’s latest attempt to warm the Earth.
The notion that non-human forces might occasionally affect the Earth’s weather can not quite be denied:
Over the past few hundred years, there has been a steady increase in the numbers of sunspots, a trend that has accelerated in the past century, just at the time when the Earth has been getting warmer.
The data suggests that changing solar activity is influencing in some way the global climate causing the world to get warmer.
but of course if this truth were recognized then it would quite knock the props out from under the latest rush to regulate under the banner of Kyoto and global warming. Even when evidence of the obvious – that the sun’s output is what really controls global temperature, and that global temperature swings regardless of human activity – is presented, it must be spun so that human agency, and thus the need for regulation, is paramount.
Laugh or cry? I can not quite decide.
