London Zoo and the global warming religion

This  precious piece of warmist propaganda is plastered all over London  Zoo. (I reproduce  the gem as it appears in the Zoo, the illiteracies and capitalisation being their own).

“ 350 – THE MOST IMPORTANT NUMBER IN THE WORLD 

350 parts per million (ppm) of carbon dioxide (CO2) in the atmosphere is the safe upper limit for almost all life

We are currently at 387 ppm and rising by 2ppm per year, higher than at any time in human history

SO WHAT?

The wild relatives of the amazing animals you see in the zoo today are already  at risk from:

Melting poles and glaciers

Rising sea levels

Spread of disease carrying mosquitoes to move, warmer places

Increased drought

Warming and acidifying oceans carbonising coral reefs and other species to extinction

In fact, all life, including human life is at peril

The World Association of Zoos and Aquaria supports the urgent call to stabilise atmospheric CO2 as far below 350 ppm as is possible

CO2  is currently “higher than at any time in human history, eh?  Well, maybe, but even that fact is far from certain.  Take this article in Nature in 2000:

‘Atmospheric carbon dioxide concentrations over the past 60 million years

Paul N. Pearson1 & Martin R. Palmer2

“Knowledge of the evolution of atmospheric carbon dioxide concentrations throughout the Earth’s history is important for a reconstruction of the links between climate and radiative forcing of the Earth’s surface temperatures. Although atmospheric carbon dioxide concentrations in the early Cenozoic era (about 60 Myr ago) are widely believed to have been higher than at present, there is disagreement regarding the exact carbon dioxide levels, the timing of the decline and the mechanisms that are most important for the control of CO2 concentrations over geological timescales. Here we use the boron-isotope ratios of ancient planktonic foraminifer shells to estimate the pH of surface-layer sea water throughout the past 60 million years, which can be used to reconstruct atmospheric CO2 concentrations. We estimate CO2 concentrations of more than 2,000 p.p.m. for the late Palaeocene and earliest Eocene periods (from about 60 to 52 Myr ago), and find an erratic decline between 55 and 40 Myr ago that may have been caused by reduced CO2 outgassing from ocean ridges, volcanoes and metamorphic belts and increased carbon burial. Since the early Miocene (about 24 Myr ago), atmospheric CO2 concentrations appear to have remained below 500 p.p.m. and were more stable than before, although transient intervals of CO2 reduction may have occurred during periods of rapid cooling approximately 15 and 3 Myr ago.”’ http://www.nature.com/nature/journal/v406/n6797/abs/406695a0.html

That is saying CO2 levels are thought to have remained below 500 ppm for 24 million years or so. That means fully fledged  mammals have survived happily enough at higher concentrations than  350 ppm and in the not too distant geological past before that date,  proto mammals and of course organic life in general managed to get along with a massive 2,000 ppm of CO2.

The other thing to note is the failure to make any mention of the other main greenhouse gases water vapour (the most prevalent greenhouse gas)  and methane. This is a common  turning of a blind eye by the warmist religionists. In the case of water vapour,  they do this  primarily  because  little  can be done about reducing it,   and in as much as man is responsible for producing water vapour,  a great deal of this results from the creation of  paddyfields. As this is  something which is done overwhelmingly by developing nations ,   political correctness kicks in to produce silence amongst Western elites. It is also very inconvenient for the man-made warming argument  to have to admit that the most prevalent  greenhouse gas is effectively beyond human control.   As for methane, that also has a politically correct dimension because  paddyfields produce a large amount of the gas.

I particularly enjoyed  the plea to reduce CO2 in the atmosphere “as far below 350 ppm as is possible. “ Reduce it very  substantially and,  others things being equal,  we would be heading for an ice age or even an earth which became  a permanent snowball.  The plea  also ignores the fact that CO2 is plant food.  Lower CO2 levels means less vegetation which means fewer  animals. Atmospheric greenhouse gases  including CO2 are necessary to maintain the planet in a state in which humans can live.

What this crass piece of warmist propaganda shows is how closed are the minds of the warmists and how  determined they are to proselytise their creed without any regard for logic or  scientific  research   which undermines their case . (It is important to understand that  the place is not just a Zoo,  but also one of Britain’s leading research institutions in the field of the life sciences, this being a consequence of its foundation by the Royal Zoological Society. Hence, they have no excuse for not understanding or being aware of the science).
