Hurricane Dolores in Los Angeles

A post from 2009 on SLB (see link)  titled Hurricanes in Los Angeles was critical of public officials in their warnings and evacuation plans ahead of that hurricane.  Of course, hurricanes almost never hit Los Angeles because the ocean surface temperature offshore Southern California is far too cold to sustain a hurricane. 

Today, however, the remnants of Hurricane Dolores 2015 sit offshore Los Angeles, and moisture from the storm's arms is turning into rain, creating flash flooding in the regions surrounding Los Angeles. 

From the National Weather Service, the following warning was issued:

AT 550 PM PDT...DOPPLER RADAR INDICATED AREAS OF STRONG AND SLOW MOVING  THUNDERSTORMS PRODUCING HEAVY RAIN ACROSS THE CENTRAL PORTION OF THE SAN GABRIEL MOUNTAINS AND ADJACENT FOOTHILLS OF THE SAN GABRIEL VALLEY ALONG THE INTERSTATE   210 CORRIDOR. VERY HEAVY RAINFALL WITH RATES OVER ONE INCH IN 30 MINUTES HAVE BEEN OBSERVED... CAPABLE OF PRODUCING FLASH FLOODING AND DEBRIS FLOWS. 

Global warming alarmists will almost certainly use the Dolores 2015 event as proof of their theories that man-made carbon-dioxide is heating the atmosphere, and that creates stronger hurricanes, floods, and storms.    Of course, when such alarmists are asked to explain similar events that occurred pre-1970, they alarmists attribute those to natural causes.   It is notable that 28 floods occurred pre-1970 according to a document published by State of California Department of Water Resources (see link) titled "History of California Flooding (2013), Table C-1"  Of the 28 floods, 3 were from tsunamis, and 3 were from failed dams, leaving 22 from rain events.   Those 22 are not all of the floods pre-1970, only the major floods. 

Sometimes it seems that the warmists simply do not understand that history did not start in 1970.   Hurricanes, floods, droughts, severe winters, heat waves, volcanoes, earthquakes and tsunamis all happened before 1970.  There were changes in local temperature, also.  

Sometimes, but rarely in my experience, a rational warmist will discuss such events.  Their response usually is along the lines of "we do not dispute the existence of severe weather events before 1970, only the severity and frequency.  Since 1970, man-made CO2 in the atmosphere has made the severity greater and increased the frequency of such events."  

Even that statement is full of problems, since some of the floods (8 of the pre-1970) were statewide in scope.  It is difficult to imagine greater severity.   The response to showing the warmists actual data is usually along the lines of "you are only considering a small part of the Earth's surface, California is far less than 1 percent of the globe.  We consider the entire globe, hence Global Warming."    When such statements are made by warmists, be sure to ask them to provide the data for your inspection.  Note whether the data is from authoritative sources, or from agenda-driven ideologues. Also note whether the data is truly global in scope, or skips over parts of the Earth where the data do not fit their agenda.  

Finally, it is always fun to ask warmists how the severe and prolonged cold weather events continue to occur, 45 years since 1970 and with CO2 levels now at 400 ppm.  Note that ice is more persistent on the US Great Lakes, Great Lakes' water temperature is colder than historic averages, ice and snow are more intense in many areas, and many glaciers are growing.
