Pakistan floods not caused by global warming but by rapid transition of ENSO phase from El Nino to La Nina

Roger Pielke Sr. cites "an excellent article by Madhav L. Khandekar (a UN Climate Report reviewer) from the latest edition of the CMOS Bulletion (Oct. 2010), The article is titled

• 2010 Pakistan Floods: Climate Change Or Natural Variability?” "...

"“A rapid transition of the ENSO phase from El Niño to La Niña between spring and summer of 2010 appears to be the key element in triggering a vigorous monsoon of 2010 over the Indian subcontinent…….the 2010 Pakistan floods,

• although seemingly unprecedented, were well within

• natural variability of monsoonal climate over the Indian subcontinent.”"...

"Madhav Khandekar is a former research scientist from Environment Canada
and was an expert reviewer for the IPCC (Intergovernmental Panel on Climate Change) 2007 Climate Change Documents. Khandekar has been in weather and climate science for over 53 years and is presently studying monsoon inter-annual variability in the context of global warming and climate change issues."...

Mr. Pielke Sr. notes Mr. Khandekar is well aware that floods can cause tragic events:

• "The article starts with the text

“Among the extreme weather events of summer 2010, the extensive floods in Pakistan and their widespread impacts

• garnered maximum attention in the media as well as in the scientific community.

• Several climate scientists expressed concern about such weather extremes becoming more common with future climate change, while the WMO (World Meteorological Organization) issued a statement that
• The extensive weather related cataclysms of July and August ( 2010) fit patterns predicted by climate scientists.

Damage due to floods and plight of thousands of people marooned over waterlogged areas were graphically covered in heart-wrenching details by most newspapers and TV news stories."...
