July 2026 set a new record for the warmest national-average monthly temperature in the Contiguous USA in both the Berkeley Earth and NOAA time series. Ongoing global warming is now starting to carry the USA beyond some of the extraordinary records set during the 1930s Dust Bowl.

This isn't necessarily a surprise, but it will have consequences for around the world. Data in the graphic from NOAA ERRSTv6

Methane is a powerful greenhouse gas, responsible for around 0.5C historical warming. But it is very short lived. Unlike CO2 it acts as a "flow" rather than stock pollutant, with impacts based on the rate of emissions rather than cumulative emissions.

The three greenhouse gases show seasonal cycles and long-term increasing trends using data from NOAA GML.
