Some un-common thoughts about Global Warming

 

The whole issue of “Global Warming” (more accurately, ‘AGW’, short for Anthropogenic Global Warming) consists of a house-of-cards construct of perhaps 3 separate assumptions (hypotheses):

·         Global temperatures and/or trends are at unusually high levels and/or rising rates

·         Human activity – and most particularly CO2 released from fuel combustion – is a significant cause of such increases.   And a crucial complementary assumption is that natural causes of temperature change are of little significance.

·         The assumption that net effects of whatever warming there may be, are harmful and (seriously so, according to most Global Warming’ advocates/ “believers”).

 

To whatever extent any of these assumptions is wrong, the argument for “fighting” global warming is itself wrong.  The case for “fighting” global warming is just as weak as a house of cards – and one on a very insubstantial scientific base.  Consider:

 

Even though scientific truths are not determined by majority vote or “consensus”, there is not anything approaching a “consensus” on even one – let alone  all three – of the three ‘AGW’ assumptions summarized above.

Over thirty-two thousand degreed scientists – many of them PhD-level experts in climate sciences – have signed a widely circulated, public statement (the “Oregon Petition”)*  explicitly questioning or rejecting one, two, or all the AGW assumptions.   The number of signers is increasing steadily, and has in recent times included an increasing number of scientists who formerly had been concerned that AGW could really be a serious problem.

On the climate drivers research front, there is accumulating evidence which supports recent hypotheses about how variation in cosmic rays, solar radiation and/or the solar wind – or any combination of these – may have strong influences, over decadal to century timescales, on earth’s climate.   Briefly, these extra-terrestrial flows seem to significantly modulate low-level cloud formation rates, particularly over some critical ocean areas.

 

If it turns out that factors not related to human activity (let alone specifically human CO2 emissions) are the dominant influence on Earth’s climate, any efforts to curtail our CO2 emissions will be a really gargantuan waste! 

 

And in any case, cutbacks in CO2 emissions reduce plant growth and biomass production worldwide – did you know that CO2 is a crucial plant nutrient?  (CO2 and water are the two primary “building blocks” for all plant photosynthesis worldwide.)
