Plummeting September 6 Temperatures In The US

September 6 used to be a very hot day in the US, but temperatures have plummeted over the past 120 years.

Over the past 15 years, there has been very little 100 degree weather on September 6, but prior to 1960, 100 degree days were quite common on this date.

On September 6, 1925 most of the southeast US was over 100F. Tennessee was 111F, Arkansas was 110F, Alabama and Mississippi were 109F, Illinois, Kentucky and Missouri were 108F, Kansas and Louisiana were 107F, Indiana and Oklahoma were 106F.

Compare vs the very cool weather of September 6, 2016 – NASA’s official Hottest Year Ever ™.

These were temperatures on September 6, 1925.

Irma Conditions Similar To The 1935 Labor Day Hurricane

The most intense hurricane in US history hit the Florida Keys on September 5, 1935. It was a very cool day across most of the US.

Compare vs. ten years earlier, when the southeastern US was extremely hot.

Conditions for Irma are very similar to 1935 with cool weather on the East Coast, and the forecast track for Irma is very similar to that of the 1935 Labor Day hurricane.

Dr Ruth – Blaming Nicole

My old friend Dr. Ruth at DMI (who gets confused by image processing) blamed Hurricane Nicole for the large increase in Greenland ice over the past year.

Guest post: How the Greenland ice sheet fared in 2017 | Carbon Brief

In a move sure to confuse and infuriate Dr. Ruth, I put her theory to the test by eliminating all of the excess ice gain which occurred before November 1, 2016 in the green line below. The green line is identical to the blue line, except that it is shifted down to match the gray 1981-2010 mean line on November 1, 2016.

What the green line shows is that Greenland gained another 75 billion tons of excess ice after November 1. So another big fail for Dr. Ruth. Blaming Nicole simply isn’t going to work. Greenland gained excess ice all through the year, summer ended early, and there was lots of excess ice gain during August, 2017.

Earth To Be Covered With Ice By 2030

Using the standard climate science practice of applying a linear fit to one small portion of a cyclical waveform, I have determined that Earth will be completely covered with ice by the year 2030.
