Drowning in Global Warming Nonsense

By -
The usual suspects are attributing the Colorado floods to global warming. This is factually incorrect.

Here is a graph of world temperatures with arrows point to the major flood events in and around Boulder, Colorado.
Moving from left to right, the leftmost arrow points to world temperatures when the previous record high flood occurred on Boulder Creek. The second arrow was the wettest day in Boulder history prior to last week. The third arrow points to the world temperature during the Big Thompson Canyon flood of 1976 that killed 140. The final arrow is last week (actually, it points to last month's temperature).

As you can see, flash floods occur in the Boulder over a wide range of world temperatures. They have not become more common with the warmer temperatures recently observed. 

Second, a recent U.S. Geological Survey study says floods are not getting worse due to CO2 increases.

So, whether it is Boulder or the nation as a whole, global warming is not causing more floods.

The forecast path of the center of Hilary has shifted a bit to the west. This increases the threat to the Southland, especially in terms of flooding.  Rainfall Note the heavy rains are forecast for Los Angeles County. Serious flash flooding may result. Because the forecast path has shifted to the west, that increases the threat of serious flooding in Los Angeles County north into Yosemite and the southern Sierra. It lessens the threat in Utah and western Arizona. While the threat of widespread flooding in Utah and Arizona lessens, note that some thunderstorms with localized heavy rain show up on the map.  In Nevada, the more western path increases the risk of serious flooding around Mt Charleston and into the central part of the state.  Here is the updated  (9am PDT) flash flood risk map. Wind There are already about 40,000 people without power in California, mostly in the center of the state.  The maps above are the peak gusts forecasted with the storm. The highest winds, in general,

Scroll up. --- Updated Information as of 8am PDT You are risking your life if you attempt to travel through the purple area.  While the rain has not begun in coastal California, I would urge you to use this time to make any preparations. Power outages have occurred already in southeast California. Here is the latest radar as of 7:55am PDT. As of 6:40am PDT , the radar indicates moderate to heavy rain falling over desert areas of Southern California and far western Arizona (click to enlarge).  Rainfall amounts for the 24 hours ending at 7am PDT show more than two inches have already fallen. There are reports from reliable sources that roads are already washed out and that people are stranded in isolated parts of the desert.  Below is a high-resolution computer model's rainfall forecast from 5am PDT to 11pm PDT Sunday. More than a foot of additional rain is forecast to fall. This will lead to catastrophic flooding.  Here is a map of current watc

The area outlined in red has a significant risk of tornadoe s the rest of the afternoon.  Below is a list of peak wind gusts so far.  Peak winds may increase farther north as the afternoon progresses.  Addition at 12 noon PDT: Sure enough, winds have increased.  Note: If you are in the San Diego area, I recommend not  traveling east on I-8. Heavy rains may cause flash flooding that will involve the highway.
