Climate Scientist Dr. Judith Curry on the National Climate Assessment

By -
My main conclusion from reading the report is this:  the phrase ‘climate change’ is now officially meaningless.  The report effectively implies that there is no climate change other than what is caused by humans, and that extreme weather events are equivalent to climate change.  Any increase in adverse impacts from extreme weather events or sea level rise is caused by humans. Possible scenarios of future climate change depend only on emissions scenarios that are translated into warming by climate models that produce far more warming than has recently been observed…

 While there is some useful analysis in the report, it is hidden behind a false premise that any change in the 20th century has been caused by AGW.  Worse yet is the spin being put on this by the Obama administration.  The Washington Post asks the following question: Does National Climate Assessment lack necessary nuance? In a word, YES.

You can read her entire critique here.

Global warming is the first hypothesis in the history of science that, according to its advocates, is unfalsifiable: Hot, cold, wet, dry, drought, flood, warm winters, cold winters, more hurricanes, less hurricanes and prostitution are all caused by it.

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,
