The lull in global warming from 1998 to 2008 was mainly caused by a sharp rise in China’s coal use, a study suggests.
The absence of a temperature rise over that decade is often used by “climate sceptics” as grounds for denying the existence of man-made global warming.
But the new study, in Proceedings of the National Academy of Sciences, concludes that smog from the extra coal acted to mask greenhouse warming.
China’s coal use doubled 2002-2007, according to US government figures.
China is one of the few places which hasn’t cooled since 1998, but why let actual data interfere with climate propaganda?
Did they just say that the solution to global warming is burn more coal?………………..
lol, yep, apparently, like erupting volcanoes, coal can simultaneously warm and cool the earth.
Yep, they admit that there’s been no warming for 13 years….only when they find something they can blame…
Next time you see record temperatures, global weirding , snow a thing of the past, more and violent anything…..
…..rub their noses in it
If there’s been no warming for 13 years, they’ve been lying out their butts……….
….and don’t have a frigging clue what’s going on, what causes what, and can’t predict a thing
Yup.
Not only that but they are also being forced to acknowledge that natural variability, in the form of reduced solar activity and the switch from positive to negative PDO, have also been factors in the lack of observed warming since 1998 which, in turn, begs the all-too-obvious question as to exactly how much natural variability contributed to the observed warming between 1979 and 1998.
CAGW is dying on its feet. The only thing left to decide is whether the lukewarmers or the sceptics shall (metaphorically speaking) inherit the Earth.
New climate science paper is released.
M. Mann is a co-author.
Null hypothesis- Any climate paper co-authored by M. Mann is garbage.
Hypothesis- this is a scientific paper with merit.
Conclusion based on details already in evidence- hypothesis has been falsified.
next.
Wrong Michael Mann.
This is Michael E. Mann, as opposed to Michael L. Mann of hockey-stick infamy.
Your conclusion still stands, though.
I love coal “Burn Baby Burn”
That’s because all the smog actually blew into Siberia causing the purple spot. The smog didn’t do a very good job of masking the warming over Moscow though.
There are ideological climate factors involved (wrong kind of politics).
Written by a team of economists!
Go to the NASA GISS site and plot temperature trends by decade. If you take into the account the El Nino of 1998, and just look at 1990-1997, the temperature trend shows a lot of regions with cooling (in fact most of them). The only recent periods where there is dominant warming is 1980-1990 and 1997-1999. My off the cuff hypothesis would be the warming from 1980-1990 was from the shift in phase of the PDO, and of course a lot of the data is corrupted by urban warming. In any case, they would probably blame Pinatubo for the 90s cooling, but with all this cooling going on its hard to see any data that supports the notion of runaway global warming caused by CO2.
Snow is a thing of the past…

hotcold based on burning of coal, targets only poor nations, or where there are no thermometers
So the huge increase in coal burning can be blamed for the lack of warming, but no one ties it to the loss of Arctic ice even though it’s well known that some of the black carbon from China gets transported to the Arctic?
My guess is that the loss of Arctic ice corresponds much better to China’s coal burning than with global temperatures.

Scott, do you know of any objective comparisons to soot found in the arctic now vs the 70s or 80s?
What did you guys do with Duncan. I was hoping he could entertain me on finding scientific information supporting this inane claim. Oh well.
Here is what I found:
http://www.epa.gov/airtrends/sulfur.html
1980-2009 – 76% Reduction of SO2 in the US.
If you check out Hawaii, the same trend is occurring.
I see nothing significant in the “man-made” aerosol behaviors in cooling the NH.

I remeber a SOx monitoring station in Barrow, but I can not find it anymore. I remeber 2 years ago that they had observed the falling SOx levels, though the theory was they could see China’s industry ramp-up. Fail, yet again.
And I thought sulphur dioxide rained out in a matter of weeks, and therefore had limited range globally. Silly me. You learn something new every day.
Soot can reflect sunlight, and it can keep heat in as well.
