The main purpose of this ongoing blog will be to track planetary 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 ETs (not extraterrestrials).😉
Main Topic: NCEI Mean Monthly Global Record Temperature Areal Tracker
(Due to a network outage, I could not write Wednesday’s post. I’m combining what I intended to write on Wednesday with Thursday’s latest information linked from Twitter.)
Dear Diary. One learns something new every day. On Wednesday I learned from some associates from the National Center for Environmental Information that a relatively new tool had been implemented by them to track average ratios for all the hundreds of surface records that come into their system on a monthly basis globally.
This appears to be the beginnings of something I have been wanting to scientifically see the last several years…a system that at least gives us a rough guide for how trends with extremes in temperatures have been going, not just on a national, but a global basis, particularly over the last year in which global warming has ramped up while that of the U.S. statistically remained at a near steady or stagnant state the last couple of years. Also, this could be the start of an improved all-encompassing global record temperature archive system, one of the items on my wish list beyond solving the climate crisis, of course. At least an improved surface records system would let many folks with some degree of education and scientific background better see how fast our climate in sinking. Right?
Speaking of that, it’s not too socking to see statistics from July and August 2023 from the new system. Take a gander:
The mean monthly temperature records product provides historical perspectives on the occurrences of warm or cold mean monthly temperatures across the globe from the gridded (5° latitude by 5° longitude) NOAAGlobalTemp. On a monthly basis, the percentage area of the globe experiencing record warm or record cold conditions is reported as a time series for the month from 1951 to the present, complementing the percentile maps, but choosing a start date with relatively uniform and broad global coverage. In addition, the ratio of warm-to-cold records is plotted as a time series. For example, a ratio value of 2 indicates that the global area experiencing record warm mean monthly temperatures over the most recent month was 2 times larger than the global area experiencing record cold conditions.
July 2023 Global Land and Ocean
During August 2023, 12.63% of the world’s surface had a record-high August temperature — the highest August percentage since the start of records in 1951.
Across the global land, 15.95% of its surface had a record-high August temperature, the second-highest percentage since records began. Only 0.50% of global land surface had a record-cold temperature. Across the global ocean, 11.09% of its surface had a record-high temperature for the month—the highest percentage on record for August—and only 0.18% had a record-cold temperature. Less than 1% (0.28%) of global land and ocean surface experienced a record-cold August temperature.
During July 2023, 9.35% of the world’s surface had a record-high July temperature — the highest July percentage since 1951.
Across the global land, 11.73% of its surface had a record-high July temperature and only 0.01% had a record-cold temperature. Across the global ocean, 8.24% of its surface had a record-high temperature for the month and only 0.10% had a record-cold temperature. Less than 1% (0.07%) of global land and ocean surface experienced a record-cold July temperature.
Only grid cells that are completely free of missing values from 1951-present are utilized in the analysis, generally limiting our domain to 45°S to 75°N. For each retained grid cell, the warmest and coldest mean monthly temperatures in the 1951-present period of record are identified for each month. These monthly records are expressed as percent areas aggregated over 3 spatial domains: global land-only areas, global ocean-only areas, and the combined global land and ocean. The spatial aggregation accounts for differences in grid cell size with latitude (i.e., cosine weighting) as well as the fraction of land and ocean areas within coastal grid cells. Monthly ratios are computed by dividing the areal extents experiencing warm records with the areal extents experiencing cold records. For seasonal and annual aggregations, the warm and cold record areal extents are summed separately before dividing the totals.
- Ratio values between 0.8 (five-to-four) and 1.25 (four-to-five) are shown in gray.
- Red circles indicate values above 1.25.
- Blue circles indicate values below 0.8.
- Dark red (dark blue) values represent one of two things:
- A ratio value that is greater than 50 (less than 0.02)
- An observation in which the warm (cold) record area is non-zero and the cold (warm) record area is zero.
- In rare cases, the warm and cold record areas are both zero, in which case the value would be shown as a dark gray circle over unity (i.e., a value of 1).

This bears repeating: During July 2023, 9.35% of the world’s surface had a record-high July temperature — the highest July percentage since 1951.
This also coincides with the fact that July 2023 was the hottest month every recorded for Earth. I’ll let you know when I see the 2023 statistics.
This also bears repeating: During August 2023, 12.63% of the world’s surface had a record-high August temperature — the highest August percentage since the start of records in 1951.
I’ll let you know when September 2023 data for these datasets is available.
