"Climate Pledge Arena"

By -
At first I thought this announcement was a joke.

Amazon has purchased naming rights to a hockey arena in Seattle and naming it "Climate Pledge Arena."
What I don't know is whether they are doing this as a cynical public relations move or whether they really believe what they are saying. Specifically,
  • There is no such thing as "100% renewable energy." It doesn't exist. If they are referring to wind and solar, those are backed up with fossil fuels. The back ups are generators, powered by (usually) natural gas, that are in "spinning reserve" mode. That is necessary because wind is so unreliable. 
  • Wind and solar generating systems usually wear out much more quickly than expected which requires even more rare earth metals to be mined and environmentally awful disposal. The huge solar blades do not break down. They will be in the earth for millennia. 
  • It always amuses me that someone is pledging to do something 30 years in the future -- by which time the pledge will be forgotten. 
If Jeff Bezos really wants to improve the environment, while also helping the less fortunate (by lowering the cost of electricity), he should spend some of his vast fortune accelerating the development of next-generation nuclear.

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,
