Wind farms causing global warming in Texas

BBC:
Wind farms can affect weather in their immediate locality, raising night-time temperatures on the ground, researchers working in Texas have shown.
They used satellite data to show that land around newly constructed wind farms warmed more than next-door areas.
The result - published in the journal Nature Climate Change - confirms an earlier, smaller study from 2010.
The scientists believe the effect is caused by turbines bringing relatively warm air down to ground level.
They suggest that turbines in other places might not produce the same value of ground temperature change.
The study area, in west-central Texas, saw a major turbine building programme in the middle of the last decade, with the number soaring from 111 in 2003 to 2325 just six years later.
Researchers used data from the Modis instruments on Nasa's Aqua and Terra satellites to measure ground temperatures across the study region and between the beginning and end of the construction boom, defined as as the difference between the average for 2003-5 and that for 2009-11.
The entire region saw a rise, but it was more pronounced around wind farms.
The researchers looked for other factors that could have affected the results, such as changes in vegetation, but found these were too small to produce the observed change.
... 
You would think this would create a dilemma for the anti energy left, but, they already hate wind farms for various reasons having nothing to do with "climate change."  The economics of wind farms is already suspect.  They, like most alternative energy sources, are inefficient and costly.  So will the EPA try to ban them now?

Should Republicans go ahead and add Supreme Court Justices to head off Democrats

Washington Post: Some Democrats eye adding more justices to the Supreme Court to change its ideological bent The once-remote idea has gained the attention of liberals angered by the GOP push to remake the federal courts. Probably the easy way to defeat this court-packing scheme is for Trump to propose doing the same thing now.  It would lead to Democrat denunciations and claims that it would be wrong, thereby blowing up any attempt by them in the unfortunate event of Democrats winning a presidential election.

29 % of companies say they are unlikely to keep insurance after Obamacare

Conn Carroll: A new survey of 368 midsize to large companies found that 29% of them are considering terminating their active employee health care plans when Obamacare is full implemented in 2014. Only 71% of employers surveyed said they did not expect to drop their health coverage, while 20% said they did not know and 9% said they were planning to exit. The latest survey, conducted by Towers Watson, echoes an ealier survey by McKinsey & Co. finding that 30% of private-sector employers were planning to drop their employee health insurance coverage by 2014. When the Congressional Budget Office crunched Obamacare's spending numbers, they estimated that only 7% of employees currently covered by employer-sponsored plans would lose their plans. ... This means the cost of the health care fiasco will be hundreds of billions more than estimated by the CBO and Congressional Democrat. It is also clear that Obama's pledge that you could keep your health care plan if you wanted t...

Is the F-35 obsolete?

Headline USA: Pentagon Fires Back after Musk Calls Its Most Expensive Project ‘Obsolete’ 'Yeah, as I'm sure you can appreciate, Mr. Musk is, currently, a private citizen, I'm not going to make any comments about what a private citizen may have to say about the F-35....'   ... ... Drones appear to be replacing jets for many operations.  The Russia-Ukraine war is an example of that.  Drones are often hard to detect and can be used for intelligence operations as well as for attacking enemy targets.  It would not surprise me to see drones engaging other drones in combat.  They also cost much less than manned fighters.
