Brisbane CO2 for 20 July 2023

Latest Data / By

Just two sites reporting for Thursday because of a power interruption at Bellbird Park. This station is back on-line and will reporting Saturday’s full data on Sunday. We will show the 21-day average up to 19 July until then.

The third chart shows NOAA’s summary of climate anomalies and events for June – which the agency confirms as the hottest June in the 174-year record of systematic data collection. 

Daily Averages – Phase 2 (See explanation of differences between Phase 1 and Phase 2 data)

For reference, latest monthly average (May 2023) from CSIRO for Kennaook/Cape Grim in NW Tasmania was 415.7 ppm. (Note – these are provisional values, subject to revision folllowing sensor re-calibrations and other checks.)

Brisbane CO2 for 19 July 2023

Latest Data / By

Carbon dioxide concentration at the three sites in Brisbane averaged 437 ppm, still a little above the average for Phase 2 data. Differences between the sites were smaller than the average  (compare charts 1 and 2).   

Globally, the estimate of global average temperature reported in the NCEP Climate Forecast System (CFS) version 2 data-set now stretches to 16 days in a row exceeding the temperature for any previous day in the 45 year record.

Brisbane CO2 for 18 July 2023

Latest Data / By

Average carbon dioxide concentration at the three sites in Brisbane rose across the course of the day on Tuesday to a mean of 436 ppm, still a little above the average for Phase 2 data.  

Globally, the estimate of global average temperature reported in the NCEP Climate Forecast System (CFS) version 2 data-set now stretches to 15 days in a row exceeding the temperature for any previous day in the 45 year record.   This is one of a series of new records – today’s third chart shows the abnormally low levels of sea ice in the Antarctic – a gap opening up since late April between this year’s values and the previous 44 years of data.

Brisbane CO2 for 17 July 2023

Latest Data / By

Average carbon dioxide concentration at the three sites in Brisbane fell slightly again on Monday to a mean of 434 ppm, still a little above the average for Phase 2 data.  

Globally, the estimate of global average temperature reported in the NCEP Climate Forecast System (CFS) version 2 data-set now stretches to 14 days in a row exceeding the temperature for any previous day in the 45 year record.   Today’s third chart is from a recent discussion of the emerging El Nino and what to look for in comparing it to the 1997 and 2015 ‘Super El Ninos”, and determining if “we are headed into a new frontier of global climate“.  More information here.

Brisbane CO2 for 16 July 2023

Latest Data / By

Average carbon dioxide concentration at the three sites in Brisbane fell slightly on Sunday to a mean of 436 ppm, a little above the average for Phase 2 data.  On any given day, a site can show a pattern that differs to the others.  On Sunday, the concentration at Bellbird Park started the day above 490 and ended it below 420 ppm, a substantial drop over the course of the day.

On the global front, just as it seemed  the estimate of global average temperature reported in the NCEP Climate Forecast System (CFS) version 2 data-set was about to end its run of record highs, the latest data-point (for Saturday) showed a tiny up-tick.  This made it 13 days in a row exceeding the temperature for any previous day in the 45 year record.   Today’s third chart shows the distribution of global temperature anomalies (differences from multi-year average).  The American west and south-west, Canadian east and the Mediterranean are regions experiencing heat-waves currently. These and other hotter than normal areas are more than off-setting cooler spots in S. America and north-central Russia. More information here.
