Hydrogeologist Steve Baker gives the weekly Water Report on KVMR our local progressive radio station at 89.5 FM and on the internet at KVMR.org. He is claiming that anthropogenic climate change is causing “extreme weather”.
I find that disturbing as California hydrologist Baker should be aware of the long-term trends that have shaped the state’s hydrology, and that California has been subjected to extreme weather for centuries long before the advent anthropogenic global warming, re-labeled climate change, was a public concern. If he was a well-read hydrologist and had read the IPCC reports on climate change he would know that the current data on floods, drought, and tornadoes have similar historical records showing no indication of becoming more severe or frequent. The IPCC concludes:
“There continues to be a lack of evidence and thus low confidence regarding the sign of trend in the magnitude and/or frequency of floods on a global scale.”
“There is low confidence in observed trends in small spatial-scale phenomena such as tornadoes and hail.”
“There is low confidence in detection and attribution of changes in drought over global land areas since the mid-20th century.”
Let’s let the flood, drought and tornado data speak to the issue. I will post on each issue in a separate post. I am not a climatologist, so my job is to find the data collected and analyzed by qualified scientists and present it for your consideration. Stay Tuned!
