Indian monsoons and climate change

Madhav Khandekar (Expert Reviewer 2007 IPCC AR4) has forwarded the short comments below as well as this short video based on his long interview with Michelle Sterling of the FOS (Friends of Science, Calgary) on the new IPCC Chief and on his assessment of Indian/Asian monsoon and its impact on close to 3.5 billion people of south Asia on an annual basis and on the the earth’s climate as a huge jigsaw puzzle which we do not fully understand. The interview was taken in mid-April 2015, long before his plans for a tour to UK and a talk at the House of Commons were finalized.

As seen here, droughts and floods have occurred irregularly for 150 years with NO trend of any kind.

“The earth’s climate is a huge jigsaw puzzle, with many pieces like the annual summer monsoon over India and south Asia, its complex interaction with large-scale atmosphere-ocean features like the ENSO  (El Nino-Southern Oscillation), the PDO (Pacific Decadal Oscillation) &  the NAO (North Atlantic Oscillation) and a host of other features like interaction with global topography, mountain ranges etc. This jigsaw puzzle still remains unsolved with most climate models not being able to simulate many of these processes above. As such, climate models’ projection of future warming of the earth’s climate must be rejected as being unsuitable for climate policy. Reducing human-CO2 emissions now is an expensive and a meaningless exercise and must be avoided. The best and the most cost-effective strategy against future climate change impacts is to develop comprehensive climate adaptation plans”.
