10 Responses to US Summer Maximum Temperatures Plummeting For Over 100 Years

  1. Anyone old enough to remember the heat waves of the 70s and 80s in the summer, will know that temps on average are getting colder in most locales. Winters are also in many parts in the world, setting yearly records for cold, snow and ice. I would guess that since 1880 all temps have declined. Eco morons – like the Nazis before them – claim to use ‘science’ to support non-existent greenhouse effects. The Nazis used ‘science’ [evolution] to justify the gassing of 6 mn Jews and 5 mn Catholics. Just a matter of time before the Eco Nazis try to follow the same plan. Hyperbole ? No. Listen to what they say about eliminating the human.

      So true. In socal I know the 70s tended to have a lot more hot and 100°+ days. Btw, today in Pasadena the high: 82°. 90 is considered cool for this time. And the highs for the next few days: 83, 84, 86. And while it says that on July 24th it will be 101, I’m finding that weather dot com often predicts 100+ temps many days in advance and then lowers the prediction by 5+ degrees as that day approaches. In socal 5 out of the last 6 summers have been unusually cool. I just wonder why is it that where I am, and probably where you are, after several decades of supposed runaway warming, it’s… colder. It makes me think that the official temperature record is not correct. Someone should look into that.

    Should that be 1980?

    I’m not buying this; I see 42 deg F as the low on a station nearby using this source:

    Spincich Lake, MI is in the UP of Michigan.

    Your data does not surprise me. I remember it being hotter in the past. But of course the alarmists are trying to convince us it is a hoax.

    There is a reason most of the believers are young. They have so little past.

    Woke up to a nice, warm July-like temp of 46F this morning…in the middle of WV.

    The EPA’s U.S Annual Extreme Heat Wave Index, 1895-2013 (last updated May, 2014), is a dead ringer for your 100 degree summer day graphic above.

    Here: http://www.epa.gov/climatechange/science/indicators/weather-climate/high-low-temps.html

    Folks should save a copy (or screen shot), as I’d imagine that at some point in time, someone at the EPA is going to realize that a clear picture of actual history is not a great selling point for their message of, “were already feeling it now. We’ve never experienced heat waves like we’re seeing today, and they are only going to get worse . . , ” and will have it taken down (or adjusted to match the message).

    Well, hopefully not as ‘worse’ as they got back in the 1930’s – in the decades prior to the birth of AGW.

    This is bad. American ‘undocumented migrant’ children won’t know what a warm summer is any more. We either need to crank up more coal plants or send the children back to warmer climes. Think of the children.

    That graph is going to go south very rapidly with this cool pattern in place.
