    Hi Tony. My first stop (OK – Drudge is first . . . but) most days of the week is here. Wondering if you can do anything with this. LAT’s piece a week back – about some ridiculous report. Was particularly suspicious about this one presentation (the rest of them are in your face, misleading to fake). Article is here: http://www.latimes.com/local/lanow/la-me-ln-california-climate-change-20180511-story.html

    The second chart: Nights are getting hotter: Extreme heat events are becoming more frequent. Heat is rising faster at night than during the day, with the greatest increases in Southern California. Nighttime heat waves, defined as lasting at least five consecutive nights, were once rare but have increased markedly since the 1970s.

    They only show back to 1950 (every graphic has a different cherry-picked starting point). Would not the UHIE be the driving mechanism here (especially for southern CA)?

    Also – the CA temp graph. LOL. In 1900 it’s 55. Then looks like a couple of decades of cooling. Next, there is the steepest rise in temps to about 56 degrees 1930ish. Stays there except for a little stretch of cooling, until about 1963. Now – this is about the beginning of any potential human footprint on global temps (1950’s – ‘late 70’s is the consensus view). So – all the warming from 1900 to 1963 – that 1 degree F, is natural, and is 1/2 of the total warming by 2011 – during approx 1/2 of the entire time scale (111 years shown). The fastest CA warming occurs when CO2 is around 300ish – and the later warming – over a much longer time scale – is when it’s approaching 400 ppm.

    The glacier bit is off the wall – don’t they know that these glaciers didn’t even form until after 1250 AD?

    The National Weather service for Nashville on twitter is claiming that this May is the second warmest on record for Nashville. This honestly hasn’t seemed that hot to me. I just barely started using my AC a little this week. Just wondering if you can do one of your comparisons of what they are saying versus reality.
