Extreme Temperature Diary- Tuesday January 4th, 2022/ Main Topic: NCEI Global and National Record Count and Ratio Summaries at the End Of 2021

The main purpose of this ongoing blog will be to track global extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as not extraterrestrials).😉

Main Topic: NCEI Global and National Record Count and Ratio Summaries at the End Of 2021

Dear Diary. This will be the second consecutive year that I’ve taken stock of record counts from the National Center for Environmental Information at the end of a calendar year. All totals are taken from the following link:


The main purpose in doing this is to glean global totals to compare to global averages and anomalies, although national totals are interesting.

I intended to get totals on 12/31/2021 to get the best figures, but the system went down for maintenance before I could do so. Also, once the system came back online on 1/03/2022, I noticed that no further updates came in after 12/27/2021. What we are left with are the best stats for 2021 given the fact that, poof-now they are gone, global totals are not archived by month and year like those for individual countries, such as the United States.

Here is what we see comparing apples to apples from the same 365-day period from 1/3/2020-1/3/2021 (keeping in mind that there have been no reports at all so far for this year on the date of this post. Also be aware that U.S. totals are part of global totals, as a whole):

Now we can compare 2021 totals with those of 2020:

Keeping in mind that global average temperatures for 2021 were roughly +1.2°C above preindustrial conditions, we see that the ratio of global daily high max to low min records (including ties) was about 2.83 to 1, which was higher than the 2.58 to 1 ratio for 2020. Other ratios are noted in the above two charts. We see once more, that in the last few years U.S. national ratios for monthly and daily records were slightly below global ratios. This would imply that the United States is heating up a bit more slowly than the rest of the globe, but we don’t know exactly why. There was not as much evidence of the global warming signature of nights warming faster than days during 2021, compared with 2022, looking at how HMX numbers did exceed HMN numbers in some datasets.

It will be interesting to see how these ratios move up as global averages rise the rest of this century. We are focused on the daily HMX to LMN because of the following scientific paper I was a part of:


It is my sincere hope to make a summary at the end of 2022 should the NCEI record count system not improve and/or change. If I’m not physically able I hope other scientists will carry on my work. Starting with 2020 I’m archiving each end of year summery in my NCEI Record Count Archive on this site.

What is the bottom-line purpose for this record research that has become my life’s work? It’s important to see how much more record heat we can expect on the planet with each seemingly minuscule uptick in global average temperatures, so that experts and those with governmental and corporate power can best prepare populations for the future of the climate crisis.

Here are some of Tuesday’s “ET’s”:

Here is some more climatology from 2021:

(As usual, this will be a fluid post in which more information gets added during the day as it crosses my radar, crediting all who have put it on-line. Items will be archived on this site for posterity. In most instances click on the pictures of each tweet to see each article. The most noteworthy items will be listed first.)

Now here are some of today’s articles and notes on the horrid COVID-19 pandemic:
