Saturday Morning Essay: The New IPCC Report

Brought to you by Peet's French Roast...

Here's your money shot from the new report of the Intergovernmental Panel on Climate Change:

Quite elegant in its presentation.  About 800 scientists, actually trained to within an inch of their lives in relevant fields of climatology, atmospheric physics, meteorology, oceanography, and paleontology, have concluded to the 95% confidence level that the predominant cause of global warming since 1950 has been the influence of human beings.  The 95% confidence level is sort of the gold standard of statistical analysis; you can almost say, in a way, that if you don't believe this, you don't really believe anything at all except shit that you yourself make up.

Making shit up, of course, is the stock-in-trade of those legions of the Dark Force known as Right Wing Think Tanks.  All of our "controversies" in the United States are generated by Right Wing Think Tanks; we think we're engaging in some sort of two-sided "discourse" on issues, but we're not.  There is reality, and there is the world of disinformation promulgated by Right Wing Think Tanks.  It's really as simple as that.  The propaganda machines of Big Oil, the Koch Brothers, the Pete Petersen Foundation - they're all in on it.  Grinding out falsehoods 24/7 to promote a financial agenda.

You can see that somewhere around 2050, the future lines begin to diverge markedly.  The Report concludes, however, that if strong mitigation (mostly, reduction in CO2) were to begin, you know, soon - then global average temperature rise can be held below 2 deg. C in 2100.  Because of the lag time between emission of CO2 and its effect on climate, we cannot wait until 2050 to begin reducing emissions.  It takes about 30 years before the effects show up, and once the temperature rise is established, it's effectively permanent.

That's the good news within the Blue probability band.  Within the Red band, involving "business as usual," you can see that global average temperature might rise 6 deg. Centigrade by 2100.  Try to imagine that.  This is a consortium of climate scientists from about 125 countries, trying to limit themselves to the most scientifically verifiable results possible (being "conservative," in other words), and in the results of their report they are behooved to tell us that the average global temperature 87 years from now (the length of one long life) will be about 10 degrees F. warmer if we keep living the way we're living now.  Just for starters, this means that the entire ice sheet atop Greenland will melt, resulting in a 7 meter rise in sea level.  That's significant.  For example, I live near San Francisco Bay, but I'm not currently living in San Francisco Bay. 

Blue Pill or Red Pill?  The summary at Realclimate.org, available right here on the Pond's blogsite, is very clear and informative.  The blogmeisters at Realcimate, guys like Michael Mann and Raymond Bradley, who were pilloried by mouth-breathing petroleum whores like Joe Barton of Texas, have been thoroughly vindicated in their warnings many years ago.  I ask you whether the Red Band does not in fact show alarming signs of forming a parabolic curve?

As The Most Interesting Man in the World might be paraphrased:  Stay Blue, my friends.
