The two major US temperature databases have released their consolidated results for 2012, and as had been expected, global warming has failed to occur for approximately the fourteenth year running. One of the US agencies downgraded 2012 to tenth-hottest ever: it had been on track to rank as 9th hottest.
The tenth-hottest result comes from the US National Oceanic and Atmospheric Administration (NOAA), one of the three main global databases used to assess planetary temperatures and the only one of the three not so far linked to political climate activism*.
The NOAA says that the 2012 average was 14.47±0.08°C, which makes it the tenth hottest in its records. Preliminary figures released last November ahead of the Doha carbon talks by the World Meteorological Organisation, which averages all three datasets, suggested that the year would be ninth hottest and NASA agrees. However the difference is not a big one: the projected WMO figure was 14.45°C.
However one slices it, the world has not warmed up noticeably since 1998 or so, though all three datasets show noticeable warming in the two decades prior to that.
Over at Salon (originally from Desmog Blog, I think) this chart is actually described as a “slam dunk” against “climate deniers.”
Most informed skeptics do not deny global warming — how could you, the world has clearly warmed over the last century (though some of us will argue that land-based metrics are exaggerating that warming). We skeptics don’t even deny that CO2 causes some warming. In my case I accept Michael Mann’s old number of about 1C of warming (before feedbacks) from a doubling in CO2.
What we skeptics “deny” is the catastrophe — that hypothesized positive feedbacks in the Earth’s climate system will multiply the initial warming from CO2 many times, raising it from a manageable one degree or less over the next century to three or five or ten degrees. Skeptics believe that temperatures will rise due to CO2, but will remain within the bounds of temperatures we have already seen over the last millenia, including those in the Medieval Warm Period during which European civilization thrived.
And we believe that the cost of economic dislocations, particularly in developing countries, from limiting fossil fuel consumption will be far worse than from merely adapting to a one degree change.
What fair-minded person could possibly imagine this black circle in any way is a rebuttal to this skeptic position?
Henrik Svensmark’s documentary on climate change and cosmic rays. Henrik Svensmark (born 1958) is a physicist and professor in the Division of Solar System Physics at the Danish National Space Institute (DTU Space) in Copenhagen.
That scientists should employ the inductive method is not the main theme of The Logical Leap; rather, the book makes the stronger claim and demonstrates that scientists must use this method in order to make progress. And many scientists are indeed making progress, even now, particularly in the applied fields. But what happens when the inductive method is misapplied, or worse, abandoned? String theory is a case in point: Some physicists accept it because it is “beautiful”, not because it was induced from observational evidence. That sort of evidence has caused many fundamental theories of contemporary physics to stagnate for more than a generation. Indeed, Harriman quotes the late Harvard University chemist E. Bright Wilson, who said, “It is very unsatisfactory that no generally acceptable theory of scientific inference has yet been put forward. Mistakes are often made which would presumably not have been made if a consistent and satisfactory basic philosophy had been followed.”
Another great one by Warren Meyer:
Alarmists like to call climate skeptics “deniers,” usually in an attempt to equate climate skeptics with holocaust deniers. But skeptics do not deny that temperatures have warmed over the last century, or even that man (through CO2 as well as land use and other factors) has played some part in that warming. What skeptics deny, though, is the catastrophe. And even more, what skeptics deny is the need to drastically reduce fossil fuel use – a step that will likely be an expensive exercise in the developed west but an unmitigated disaster for the poor of Asia and Africa. These developing nations, who are just recently emerging from millennia of poverty, need to burn every hydrocarbon they can find to develop their economies.
