A recent paper in Nature claiming an increase in extreme rain events 1951-1999 correlates with “AGW-climate change” has been given the usual uncritical acclaim in our GreenLeft media. I enjoy the originality in ABC headlines. Dr Roger Pielke Sr. has reviewed the paper.
I was surprised to see the Min et al paper only quote data for their “5 day consecutive rainfall” to 1999 – over a decade ago. Rainfall data must be in a worse state than I imagined.
I was curious to see what total rainfall data showed for the 20 to 60 degrees north band in the Northern Hemisphere –
Using data I can access at the KNMI Climate Explorer up to 2010, look under “Monthly observations.”
Running the linest function in Excel over the 60 years of GHCN rain 1951-2010 – the daily rainfall anomaly has increased by 0.00026mm PA which equates to 0.0156mm over the 60 year period – which in turn equates to an extra 5.69mm PA.
I seriously doubt anybody would notice a ~1% increase in their average rainfall over 60 years – but imagine the panic stories from the warmists if the climate were drying !!
