WTF? We just experienced 4,000 years of global warming in two decades

Graphic by Barry Saxifrage

A new study published in the journal Science shows how freakishly extreme global warming has become in the last few decades.

The scientists from Oregon State University and Harvard University used dozens of sources of ice cores and sediment cores from around the world to reconstruct the Earth’s temperature record for the last 1,100 decades. This detailed record stretches back much farther than previous studies.

Here is my chart of the temperature data they uncovered:

 

Global temperatures rose slowly for thousands of years after the end of the last ice age. Temperatures peaked around 5,000 BC, at a level close to where we are today. Then temperatures declined slowly for thousands of more years.

Now, suddenly, the global temperature has started rocketing upwards. Far more troubling than the actual temperature is the fact that the changes are accelerating dramatically.

The century from 1860 to 1960 saw rapid warming. The next two decades more than doubled that warming. And then the next two decades – 1980 to 2000 – went ballistic, piling on thousands of years of warming.

Last week another study was published showing global warming has continued to accelerate since then, with dramatic warming of the world's oceans in the last 15 years.

Just getting started

As unprecedented as this temperature explosion has been, it will unfortunately look tiny compared to what global experts now say is coming on our current dirty energy path.

The amount of climate pollution humans are releasing has been accelerating with no signs of slowing down. Last year broke the record for largest increase.

The normally staid pronouncements of international institutions are starting to crackle with concern:

Cough, cough, cough. Ouch.

CO2 and global warming reminds me of tobacco smoking. Everybody has known, one way or another, that it is very very dangerous to smoke, but most addicts continue/d because their breathing seemed normal until that one day that something slightly different was noticed including, perhaps, a minor and temporary chest pain which just as suddenly went away. Mostly it was the slight breathing change -- not major, but something.
A small lingering doubt arose in the back of your mind, but it was easily dismissed as you bought more cigarettes. Advance several months or years, and the doctor or two passes the diagnosis sentence: death is pending, soon, maybe a year or two down the road, but very painfully irreversible.
CO2 and global warming reminds me of tobacco smoking: a unnecessarily early and acutely painful death!

 

the scale of time

Here's another excellent look at why the planet can't cope with the changes we're forcing on it in such a short time span. Wakening the Krakenhttp://skepticalscience.com/Wakening_the_Kraken.html But like all of geology's 'scale of time' lessons, this one also shows that the only long term effect our extractive culture may well leave behind is a thin shiny line in the sedimentary record.

You've gotta be joking!

Methinks you need to take a closer look at the quality of the science in this paper.

Watts and antiscience

Citing Anthony Watts to attack climate science is like citing Answers in Genesis to attack evolutionary biology.

Time for direct action against fracking climate crime!

So, maybe instead of getting depressed about this you should go do some direct action training? http://calamites.resist.ca/?p=462

Dire news

James Hansen, of Goddard/NASA who started the whole AGW ball rolling in 1988, now says"

the effect [forcing] of man-made greenhouse gas emissions has fallen below IPCC projections, despite an increase in man-made CO2 emissions exceeding IPCC projectionsthe growth rate of the greenhouse gas forcing has "remained below the peak values reached in the 1970s and early 1980s, has been relatively stable for about 20 years, and is falling below IPCC (2001) scenarios (figure 5)."the airborne fraction of CO2 [the ratio of observed atmospheric CO2 increase to fossil fuel CO2 emissions] has decreased over the past 50 years [figure 3], especially after the year 2000Hansen believes the explanation for this conundrum is CO2 fertilization of the biosphere from "the surge of fossil fuel use, mainly coal.""the surge of fossil fuel emissions, especially from coal burning, along with the increasing atmospheric CO2 level is 'fertilizing' the biosphere, and thus limiting the growth of atmospheric CO2.""the rate of global warming seems to be less this decade than it has been during the prior quarter century" http://hockeyschtick.blogspot.co.uk/2013/03/hansens-mea-culpa-says-man-made-global.html

Whatever warming we experienced is going away very fast, so instead of carrying on about warming, we must start preparing for a long term cooling.

Wow. Climate change deniers are now making up absurdities and putting them into Jame's Hansen's mouth. Your link isn't event a direct one to Hansen. What a joke.

Dancing to the corporate waltz.

As long as it is profitable, the prophets will continue to urge us to dance to their tune. But I rather like the article printed here a few weeks back about the 2013 BP Energy Report.

In this latest report BP outlines where in the world it is looking for carbon energy such as oil, coal, gas,  how much is left in their active sites, and how large their profits will in the coming year.

The report also reminds the reader that just because BP produces all that carbon energy, it is up to each of us as to how much of it is used. Use it all and as Christine Lagarde, head of the IMF stated in her famous statement - "Use it all and your kids will be grilled, fried, and roasted with global warming."

Now there is a woman with balls! Cheers.

I love that graph you

I love that graph you provided above, the one with the gently sloping curve that shows a small uptick at the end. The little uptick is then extrapolated into a wicked virtical SPIKE.  It reminds me of my sons last basketball game where he got a couple of baskets in the final few seconds, getting a similar uptick at the end.  If I extrapolate like they did in the graph, he should have an additional 14,464 points in the next game. Wow, not bad.

I love climate science!

cheers

 

Global Warming May Not be Man Made

GLOBAL WARMING MAY NOT BE MAN MADE

Dr. Larry Vardiman (scientist and physicist) of the Institue for Creation Research says:

"One possible scenario may be found in a recent series of articles by Henrik Svensmark and Nigel Marsh, cosmic ray specialists from Denmark, who have shown an indirect connection between galactic cosmic ray (GCR) intensity and global temperature.7,8,9 They are studying the influence of the Sun on the flow of GCR to Earth. The Sun's changing sunspot activity influences the magnetosphere surrounding the Earth permitting more GCR to strike the Earth during high periods of activity.

When the Sun is active, the intensity of GCR striking the Earth is increased, causing more ionization in the atmosphere, creating more carbon-14, and possibly creating more cloud condensation nuclei (CCN). This increase in CCN, in turn, appears to create more low-level clouds which cool the Earth. When the Sun is quiet the GCR intensity striking the Earth is reduced, allowing the Earth to warm. Svensmark and Marsh have shown a striking statistical correlation between sunspot activity and global cooling and warming over the past 1000 years.

The recent rise in global temperature may partially be due to current low solar activity supplemented by a recent increase in carbon dioxide concentration measured at Mauna Loa. The connection which still needs further study is the production of CCN and clouds by GCR." 

There is a good deal of science showing that global warming is not mad made. Yes, we still should have pollution controls, as we already do, but not to the extreme because it will unnecessarily hurt business.
