From NOAA’s April 2023 Global Climate Report: April 2023 was the fourth-warmest April for the globe in NOAA’s 174-year record. The April global surface temperature was 1.00°C (1.80°F) above the 20th-century average of 13.7°C (56.7°F). The 10 warmest April months have occurred since 2010. April 2023 marked the 49th consecutive …

The image here is the annual average temperature anomalies in 2022 compared to  the 1981-2010 baseline average. The image uses data from the Berkeley Earth high-resolution data set as noted in the article Introducing the Berkeley Earth High-Resolution Dataset by Robert Rohde (3/28/2023): The new Berkeley Earth High Resolution Data …

From NOAA March 2023 Global Climate Report: March 2023 was the second-warmest March for the globe in NOAA’s 174-year record. The March global surface temperature was 1.24°C (2.23°F) above the 20th-century average of 12.7°C (54.9°F). March 2023 marked the 47th consecutive March and the 529th consecutive month with global temperatures, …

The NASA post NASA Uses 30-Year Satellite Record to Track and Project Rising Seas (3/17/2023) has this to say (with calculus language): Since satellites began observing sea surface height in 1993 with the U.S.-French TOPEX/Poseidon mission, the average global sea level has increased by 3.6 inches (9.1 centimeters), according to NASA’s Sea …

NASA calls this a climate spiral. The visualization is well done, so watch it. The NASA page includes a link to the data used to make the visualization.

From the NOAA article A look at all 173 of NOAA’s new global temperature maps by Rebecca Lindsey (2/17/2023): Last week, NOAA National Centers for Environmental Information released a major update to the agency’s global surface temperature dataset. The new product tracks temperatures back to 1850, adding 30 additional years to the historical …

The Antarctic set a new record sea ice minimum at 1.788 million square kilometers beating out last years 1.924 million square kilometers. The graph here comes from the National Snow and Ice Data Center’s (NSIDC) Charctic Interactive Sea Ice Graph.  This is a great tool that allows the user to …

From NOAA’s January 2023 Global Climate Report: January 2023 was the seventh-warmest January for the globe in NOAA’s 174-year record. The January global surface temperature was 1.57°F (0.87°C) above the 20th-century average of 53.6°F (12.0°C). January 2023 marked the 47th consecutive January and the 527th consecutive month with global temperatures, …

Currently, 2022 is the record minimum for Antarctic sea ice extent, but based on the graph here from the Charctic Interactive Sea Ice Graph from NSIDC 2023 seems primed to beat that record.  The Charctic interactive Sea Ice Graph is a fun tool that lets users select years to graph. …

In a follow up to the last post, How much has sea level risen locally? (12/1/2022), we have the IPCC Sea Level Projection Tool. The NOAA sea level trends tool looks at the historic data and adds linear regression lines. The IPCC tool has projections based on the different IPCC …
