Climate change and the South Asian summer monsoon

The vagaries of South Asian summer monsoon rainfall impact the lives of more than one billion people. A review in Nature Climate Change (June 24 online issue) of over 100 recent research articles concludes that with continuing rise in CO2 and global warming, the region can expect generally more rainfall, due to the expected increase in atmospheric moisture, as well as more variability in rainfall.

In spite of the rise in atmospheric CO2 concentration of about 70 parts per million by volume and in of about 0.50°C over the last 6 decades, the All India Rainfall index does not yet show the expected increase in rainfall. The reviewers Andrew Turner from the Department of Meteorology at the University of Reading and H. Annamalai from the International Pacific Research Center at the University of Hawaii at Manoa give several reasons for why the region's observed rainfall has not yet increased, among them are inconsistent rainfall observations, decadal variability of the monsoon, the effects of aerosols resulting from industrialization, and land-use changes.

Regional projections for devastating droughts and floods--which are most meaningful for residents living in South Asia-- are still beyond the reach of current climate models, according to the reviewers' detailed analyses of the present state of research. The authors conclude that in order to make regional projections that can help in disaster mitigation and in adapting to , the following is needed: establishing more consistent rainfall datasets by expanding observations to include, for example, agricultural yield; a better grasp of the complicated thermodynamics over the monsoon region and of the interactions among , land-use, aerosols, CO2, and other conditions; and an evaluation in coupled circulation models (which allow feedbacks among variables) of those processes that have been shown in simpler models to affect the monsoon and rainfall.

Reality: "the All India Rainfall index does not yet show the expected increase in rainfall."

"Regional projections for devastating droughts and floods--which are most meaningful for residents living in South Asia-- are still beyond the reach of current climate models,"

Translation: We lie, say the world will end, and then it doesn't. But keep giving us money to lie some more.

If only I could read anything into information that is put in front of me, like you guys. How validating the world would be!

Computer models of weather patterns are only as good as the data and the software the number-crunching speed of the computers.
Making a crude, large-scale model is relatively easy. Getting progressively higher resolution is hard. It was only in the nineties climate models got enough resolution to reproduce Sahara, for instance.
Expected problems with making better models are hardly proof of the world-wide conspiracy the denialbots see everywhere.

Then you should sign up with the climate "scientists", because they still can't do that.

"Climate" models predict doom over and over gain and they turn out to be spectacularly wrong. The are like the Wile E. Coyote's of science.

The evidence is visible to all around, if you choose to see. "Denialbots" I know are becoming quieter about climate change, as they begin to confront the difference between what their eyes see and what is reported by the corporate propaganda, er, media.

I shall repeat the links I have provided in the past for VDs benefit to demonstrate his refusal to learn. On the other hand, considering it only takes a third grade education to understand the numbers and graphs, maybe he hasnt gotten there yet.

All five official climate data centers (NASA GISS, RSS MSU, UAH AMSU, HADLEY CRU, and NOAA NCDC) report that global temperature has declined since 1998. http://www.friend...p?id=453
GISP2 Greenland ice core shows global temperature was warmer for 9,100 of the last 10,000 years.

In the last 600 million years global warming has occurred before CO2 increased, not before.

Yup. climate models fail to predict the weather.

Why do you insist on claiming that they should?
Where do you see me using the word "weather," or suggesting climate models should predict the weather?

Are you terminally brain dead?
Apparently, you are.

Does anyyone else have trouble accessing VD's links? They seldom work for me. I just keep getting a page which redirects me to some advertisement for "Google Drive."

Not a refusal to learn, saying it has cooled since the warmest year on record is simply not even close to a valid point...for anything.


Sure it is for various reasons:

1) "On Record" ignores the MWP which was global.

2) Temperature, as predicted by the IPCC, was to keep climbing at .2C per decade. Meaning it should be .4C warmer than it was in 1991 and .2C warmer than 2001.

1991 0.213
2001 0.408
2011 0.339

Epic Fail. Theory wrong. Go back to drawing board.

It's been cooling since 1998. According to NASA, the warmest years on record were 2005 and 2010.

I can't even fathom what point you thought you were trying to make when you typed the above statement
Then you're an idiot. It was to counter your claim that we're only "saying it has cooled since the warmest year on record."

And interestingly, the HadCRUT3 data shows there's been no global warming since before the warm peak of 1997-1998:

Finishing my earlier post:
From the National Climate Data Center, the Mauna Loa Observatory, the Carbon Dioxide Analysis Center, the Hadley Climate Research Unit, the University of Colorado, the strength of correlation of temperature changes to CO2 from 1897 to 2007 is 0.43; to oceanic oscillations from 1895 to 2007, 0.57; to solar intensity from 1895 to 2007, 0.85; but to CO2 from 1987 to 2007, only 0.02.
http://wattsupwit...han-co2/

Temperature cycles since 1900 corresponding to oceanic oscillations and sunspots project cooling until 2030; warming, 2030 2060; warming, 2060 2090.

A case has been made that the real driving force of the 60 year climate cycle is the center of mass of the solar system (CMSS) and its speed (SCMSS).

XQZME; that is all well and good for an industrial shill. My money is on "the effects of aerosols resulting from industrialization, and land-use changes."

Jun 26, 2012
your the one who said that it has been cooling since 1998, then as though it would somehow prove you correct, site 2 years AFTER 1998 that were warmer,


Aren't you the one that claimed:

"...saying it has cooled since the warmest year on record is simply not even close to a valid point...for anything. That's like saying that the world is drying up after citing that it has rained less in every year since the one where it rained the most."

...now you're playing at moving the goalposts.

What's the matter, can't win an honest argument?

Why are AGW alarmists so dishonest?
