A Very Mild May In The US

The frequency of hot May days has declined sharply in the US over the past century, with this year being just about average.

However, the average temperature this month has been in the top five.

Afternoon temperatures have been much cooler than 1934.

 

Maximum temperatures are decreasing, minimum temperatures are increasing – so the daily range in temperatures has plummeted.

One of the main reasons for the warmer nights and cooler days is the latent heat of water.  The US is getting wetter and having fewer droughts, so we get more evaporation during the day and more condensation at night. This moderates both daytime and nighttime temperatures.

The hottest May was also the driest May in the US. During May, 1934 most of the US was in severe or extreme drought.  That was also the May with the largest diurnal temperature range.

On Memorial Day weekend 1934, North Dakota reached 111 degrees, and almost the entire Great Plains was over 100 degrees.

The propaganda about hottest May ever is about to start, and I wanted everyone to be prepared with facts.

Canadian Climate Experts

Canadian climate experts Katharine and Catherine team up to explain why warm days are climate and cold days are just weather.

Right after Climate Barbie bragged about a warm day in New York at the end of February, New York State had their coldest March/April in over 40 years.

D-Day Approaches For Climate Alarmists

I warned alarmists at the beginning of the month that their day of reckoning would come near the end of May, and it is nearly here. Arctic sea ice volume is the highest in five years, and much higher than 10 years ago. Ice is melting very slowly, and volume is getting very close to the “normal” line.

Plummeting May 26 Temperatures In The US

May 26 temperatures in the US have declined sharply since about 1910.

On this date in 1911, almost the entire eastern US was over 90 degrees.

Similar story in 1914, with 90 degree weather up into Vermont.

So Why Tamper With The Data?

Eli Melaas is bragging that Blue Hill, MA has the best temperature record in the US.

And he provided this graph.

This is what the actual USHCN daily data looks like.

I plotted four versions of the graph – Melaas, USHCN raw daily, USHCN raw monthly, and USHCN adjusted monthly. As you can see there is a huge spread, other than the two raw data sets which agree almost exactly.

Here is the graph from the NOAA web site. Essentially identical to the USHCN adjusted.

Blue Hill is one of the few USHCN stations where NOAA warms the past with the adjustments. Melaas version of the data shows a lot more warming than other data sets. Here is the difference between Melaas and USHCN adjusted temperatures.

Here is the difference between Mellas and USHCN raw temperatures.

If the Blue Hill station is so good, why is the data being tampered with? And why does Melaas’ graph show so much more warming than the other graphs?

Plummeting May 25 Temperatures In The US

May 25th temperatures have been declining in the US since the 19th century, with recent years among the coolest.

 

On May 25, 1911 most of the US east of the Rockies was above 90 degrees., with 100 degree temperatures in Oklahoma, Illinois and South Carolina.

On May 25, 1967 there was a very intense heatwave centered over Nebraska, with Hartington, Nebraska reaching 107 degrees, and many surrounding states over 100 degrees.

Terrifying Times For Climate Alarmists

Arctic sea ice volume is highest in five years, and approaching the “normal” line.

It has been ten years since Mark Serreze and David Barber predicted an ice-free North Pole that summer, and I countered with an article in The Register “Arctic Ice Refuses To Melt As Ordered

North Pole May Be Ice-Free for First Time This Summer

Arctic BS Continues

DMI and NSIDC continue to show Arctic sea ice extent declining.

Plummeting May 24 Temperatures In The US

May 24 afternoon temperatures have been declining in the US since the 19th century, and the frequency of hot days has plummeted – with recent years being among the coolest on record. On May 24, 1926, temperatures over 100 degrees were reported in South Dakota Nebraska, Arkansas and Arizona. Kennebec, South Dakota was 105 degrees on both May 23 and May 24 that year.

On May 24, 1939, Madison, Indiana was 100 degrees. They had 100 degree weather from May 24 to October 8 that year, and 90 degree weather from April 24 to October 20.

One hundred degree temperatures on May 24, 1939 were recorded in Indiana, Missouri, Iowa, Nebraska, Kansas, Oklahoma and Texas.

The Incredible Heatwave Of 1921

On this date in 1921, the Eastern two thirds of the country was extremely hot, with Caruthersville, Missouri at 102 degrees and Hobart, Indiana at 100 degrees.

The heatwave of 1921 never let up all summer. Caruthersville had 71 days over 100 degrees.

1921 had the third highest average maximum temperature in the US since 1895

If we had a summer like that now, climate scientists would be 100% certain it was due to CO2, and would demand immediate world communism.
