As the global warming hoax dramatically implodes, still more barking madness from your mainstream media

Economic View - Fighting Global Warming - A Small Price for a Large Benefit - NYTimes.com
FORECASTS involving climate change are highly uncertain, denialists assert — a point that climate researchers themselves readily concede. The denialists view the uncertainty as strengthening their case for inaction, yet a careful weighing of the relevant costs and benefits supports taking exactly the opposite course.

Organizers of the recent climate conference in Copenhagen sought, unsuccessfully, to forge agreements to limit global warming to 3.6 degrees Fahrenheit by the end of the century. But even an increase that small would cause deadly harm. And far greater damage is likely if we do nothing.

The numbers — and there are many to choose from — paint a grim picture. According to recent estimates from the Integrated Global Systems Model at the Massachusetts Institute of Technology, the median forecast is for a climb of 9 degrees Fahrenheit by century’s end, in the absence of effective countermeasures.

Scientists say that even the 3.6-degree increase would spell widespread loss of life, so it’s hardly alarmist to view the risk of inaction as frightening.

In contrast, the risk of taking action should frighten no one. Essentially, the risk is that if current estimates turn out to be wildly pessimistic, the money spent to curb greenhouse gases wouldn’t have been needed to save the planet. And yet that money would still have prevented substantial damage. (The M.I.T. model estimates a zero probability of the temperature rising by less than 3.6 degrees by 2100.)

Moreover, taking action won’t cost much. According to estimates by the Intergovernmental Panel on Climate Change, a tax of $80 a metric ton on carbon dioxide — or a cap-and-trade system with similar charges — would stabilize temperatures by midcentury.

This figure was determined, however, before the arrival of more pessimistic estimates on the pace of global warming. So let’s assume a tax of $300 a ton, just to be safe.

In short, the cost of preventing catastrophic climate change is astonishingly small, and it involves just a few simple changes in behavior.

Most people would pay a substantial share of their wealth — much more, certainly, than the modest cost of a carbon tax — to avoid having someone pull the trigger on a gun pointed at their head with one bullet and nine empty chambers. Yet that’s the kind of risk [is it?] that some people think we should take.

A 0 probability for a chaotic system? Now we have entered the realm of scorcery.
