Planetary Record Temperature Trends for 2017

I have been using the following NCEI site to do my U.S. record statistics for years.

https://www.ncdc.noaa.gov/cdo-web/datatools/records

Recently I have used the site to investigate record temperature trends in other countries such as Canada and Russia. Not many people know that the site keeps tallies of all records coming in from the entire planet. There is a menu for global tallies. Unfortunately, the site does not archive monthly running totals for the entire Earth. It does so for individual countries, however. In order to find an individual record set or tied outside of the U.S. you must go to the country of origin in menus since there is no “world” location within the site archiving tallies. Also, unfortunately, as far as I can tell, “poof”, once the year ends and the site starts to tally 2018 records, the 2017 tallies for the globe won’t be archived, and those numbers will disappear.

Some science and trends, however, can be gleaned from the global tallies. As of this post on May 28, 2017 we have the following daily record statistics added since 1/1/2017:

5/28/17: High Max        High Min           Low Max         Low Min

U.S.:        15,201               18,098              5,726            3,042

Global:    22,152               26,115               7,796            5,515

The vast majority of record reports in the NCEI site come from the United States. It is very interesting that the stats both in the U.S. and globally stack up such that high mins are the most followed by high maxes, then low maxes, with the least number being low mins, which adds more weight to my arguments about moisture affecting the way temperatures are behaving during the night and day in a warming world.

The ratio of DHMX to DLMN through 5/28/17 in the U.S. is about 5 to 1. The ratio of DHMX to DLMN through 5/28/17 globally is about 4 to 1.

It’s no wonder since the planet, so far, is having its second warmest year on record (second only to 2016).

I will be starting ongoing ” U.S. Summer Heat Diary” posts on June 1st. We will dissect, as much as possible using more technical meteorological tools than what I have presented in prior posts, the interaction between weather patterns and any heat waves enhanced by carbon pollution. Should cooler than average conditions occur during the summer, we will investigate those patterns as well.
