Gases, gases everywhere, nor any stop to thinkRichard Treadgold | May 28, 2012
Emissions of greenhouse gases are quoted everywhere to illustrate how humanity is sending the world to hell in a hand basket.
The articles make much of “emissions” from various countries, from the developed and the developing worlds. How many know that these vast, hugely important quantities are not even measured?
They’re only calculated from reported energy use — and they are far from reliable. That’s the first point. The second point is that emissions lead, presumably, to a global temperature increase. If they didn’t, there wouldn’t be a problem, would there?
But emissions don’t automatically mean higher temperatures. For a start, about 45% of human emissions — regardless how they increase — are absorbed somewhere in the gigantic natural system. Nobody knows where it all goes. It’s immensely complicated to track our puny emissions of carbon dioxide as they mix with the truly gargantuan streams out of and into forests and the oceans.
So most authors make no attempt to convert the net emissions into a temperature increase, but why not, actually?
The main reason would be that nobody — and I mean nobody, from the IPCC, NASA, the CRU at East Anglia and Al Gore all the way down to me — has the foggiest idea of the temperature that will result from these emissions.
Amazing, eh? There’s no knowledge or evidence of the inconvenient disaster we’re supposed to be creating with our selfish lifestyles. This gives rise to two questions:
- Why does nobody demand some evidence?
- What has persuaded everyone, without evidence, that there’s a problem?
