California is sunny too. Do you suppose India is backing up all that new solar with natural gas plants like California is? |
There seems to be room in the US market for gasoline powered vehicles, plug in hybrid vehicles and electric only vehicles.
Why does another country need to use the "one size is the only size" approach that you deem worthy?

Of which about 1.5 degrees F comes from global warming. |
So you are saying that the records set are only 1.5 F? Just wondering, that seems ill-informed. And then you have to be able to prove that the new records should reflect differences back to when the 1.5F was first measured against. Compare to records in the 1880's.....not just one isolated cherry picked data point record but the set of recent records.

The atmosphere has a certain amount of variability, inherent to a spinning unevenly heated fluid. This makes up the majority of any temperature departure from normal, perhaps +- 30 degrees F In the upper mid latitudes. In addition to that, we have tacked on perhaps +1.5F due to global warming and another few or so degrees for a typical city due to land use changes. So we made this heat wave worse, but the bulk of it is natural.

Not so at all. Warming of the arctic has resulted in a smaller heat exchange between the equatorial latitudes and the high latitudes. As a consequence the jet stream has slowed in the mid-latitudes and frequently loops form to cause unusually extreme conditions in certain regions. This year in the Eastern Pacific this has resulted in above normal sea surface temperatures to further enhance persistent high pressure and below normal rainfall and warmer than normal temperatures in Alaska through the Yukon and northern BC and Alberta.
To say that the only affect of global warming on conditions in certain parts of the globe is like saying the average between the top of your scalp and the bottom of your feet is your belly button and nothing else matters.

We've been over this recently but I guess you missed it. Blocking as a result of a loopy jet stream is a hypothesis for which there doesn't seem to be much observational evidence. But of course it fits the preferred narrative so we keep hearing about it as if it's established fact.
Revisiting the evidence linking Arctic amplification to extreme weather in midlatitudes
Abstract:
"Previous studies have suggested that Arctic amplification has caused planetary‐scale waves to elongate meridionally and slow down, resulting in more frequent blocking patterns and extreme weather. Here trends in the meridional extent of atmospheric waves over North America and the North Atlantic are investigated in three reanalyses, and it is demonstrated that previously reported positive trends are likely an artifact of the methodology. No significant decrease in planetary‐scale wave phase speeds are found except in October‐November‐December, but this trend is sensitive to the analysis parameters. Moreover, the frequency of blocking occurrence exhibits no significant increase in any season in any of the three reanalyses, further supporting the lack of trends in wave speed and meridional extent. This work highlights that observed trends in midlatitude weather patterns are complex and likely not simply understood in terms of Arctic amplification alone." https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/grl.50880
Exploring recent trends in Northern Hemisphere blocking
Abstract:
"Observed blocking trends are diagnosed to test the hypothesis that recent Arctic warming and sea ice loss has increased the likelihood of blocking over the Northern Hemisphere. To ensure robust results, we diagnose blocking using three unique blocking identification methods from the literature, each applied to four different reanalyses. No clear hemispheric increase in blocking is found for any blocking index, and while seasonal increases and decreases are found for specific isolated regions and time periods, there is no instance where all three methods agree on a robust trend. Blocking is shown to exhibit large interannual and decadal variability, highlighting the difficulty in separating any potentially forced response from natural variability." https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2013GL058745

Seems like the abstract takes Artic Warming and Sea Ice loss as a given, but postulated that this would increase "blocking" , but found no link between the warming and loss of sea ice and "blocking"
This doesn't sound like a refutation of the occurrence artic warming and loss of sea ice too me...

That's good because it's not.

who needs to refute what is well within the range of natural variation anyway?

No, it is not a good article. 
"CO2, like all gases, has an absorption spectrum. That is, it only absorbs certain wavelengths of energy. The problem is that there are only so many photons of energy at that spectra emitted from the Sun that strike the Earth's atmosphere; once you've absorbed them all more CO2 in the atmosphere doesn't do anything to make the planet warmer because there are no more photons of the appropriate spectrum to be absorbed.
This is physics and those are laws, called such because there is no way to violate them."
The author is utterly clueless about the theory he is disputing. The fact that the CO2 absorption bands were already saturated is taken into account in all aspects of Anthropogenic Global Warming theory. The discovery is attributed to Arrhenius and it has been known for over 100 years. The theory revolves around a reduction in thermal radiation, not an increase in absorption. He also twice wrote "spectra/spectrum" when he meant "wavelength." Not a mistake that a person with a clue would make twice.
No point in giving the author the benefit of the doubt. If he were arguing in good faith, he would go online and figure out what he is actually trying to refute. The rest of the stuff is no better.

Oh my. Thats taking stupidity to the next level.
