A balanced climate change article

http://business.financialpost.com/2014/09/22/judith-curry-an-unsettled-climate-for-climate-summit/

From one of my favourite climatologists who, a decade ago, was touting the hurricane/climate change link as co-author of a couple papers on the issue.  However throughout the past decade, through discussions on her blog, her position has moderated drastically, acknowledging that models are not matching real data and there is far too much uncertainty to make economic policies that would be detrimental.

Here is an article profiling JC.

Texas drought update.

Previous post here.   Three maps to show today. The first two maps show the progression of drought status.  Compare these with the one in the previous post.   The third maps is the predicted rainfall over the next four days.   Most of the deep red in Texas and Kansas will be eliminated.



California is still suffering though.  That'll change when the El Nino moisture kicks up.

From the last article:
"5. There is not a strong scientific basis for claiming a discernible effect of human-caused climate change on hurricanes, floods, tornadoes or drought."

What's left for CAGW?  Maybe only the AGW part, in part....

New Summary for Policy Makers (SPM) from the IPCC

With the MSM falling over themselves to proclaim how certain scientists are that man is causing global warming...

Some reactions:

http://wattsupwiththat.com/2013/09/27/new-ipcc-climate-report-already-obsolete-2/

I think it also helpful to note that there is a much less emphasis on GHG (greenhouse gases) such as CO2, but also on "other" anthroprogenic changes.  As touched on by Judy Curry post, what will the IPCC say when the current 10 year negative trend (not pause) extends out to 15 or 20 years (as I think it will)?  Will they admit that they were wrong?...not bloody likely.

As I comment in the national post article: This report is out of date already, stillborn, as recent studies that didn't make the deadline for incorporation into this report ARE cast doubt on the severity of AGW. The only way that the IPCC can raise their certainty is by being more certain about a more vague criteria...

But one of my favourite reaction is Ross McKitrick's comment here:

SPM in a nutshell: Since we started in 1990 we were right about the Arctic, wrong about the Antarctic, wrong about the tropical troposphere, wrong about the surface, wrong about hurricanes, wrong about the Himalayas, wrong about sensitivity, clueless on clouds and useless on regional trends. And on that basis we’re 95% confident we’re right.

Next IPCC report

Most of you are probably not aware of this, but the UN organization for Climate Change, the IPCC,  is shortly issuing their next report (done every four years), AR5, supposedly showing the current state of climate science.   As you might expect, there is a lot of controversy about it with various "leaks" coming out.   If you're interested, here are some articles about it:
