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.

Midnight: The East Coast Threat for Tornadoes and Severe  Thunderstorms Has Ended 3:50pm. Tornado watch for the Middle Atlantic Region. 2:30pm Tornadoes are also forecast in the South. 2:20pm. A couple of tornadoes, hail and wind gusts to 65 mph are possible with these storms. This includes NYC and Philadelphia.  1:05pm. The tornado risk has been extended northward into New York. The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

Note: An Updated Forecast is Available HERE Freezing Rain The National Weather Service has now issued winter weather advisories, two warnings and a watch. It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue is 0.1 to .25 inc
