Temperatures rising fast March 2023
Monthly Northern Hemisphere Land Temperature Anomaly
Temperatures have been rising fast in March 2023. The image below shows the Monthly Northern Hemisphere Land Temperature Anomaly up to March 2023, with two trends added. The blue trend, based on Jan.1850-Mar.2023 NOAA data, points at a 3°C rise in 2032. The magenta trend, based on Oct.2010-Mar.2023 NOAA data, better reflects variables such as El Niño and sunspots, and illustrates how they could trigger a rise of more than 5°C in 2026. Anomalies are versus 1901-2000 (not versus pre-industrial).
Reducing emissions is the right thing to do, even though it comes with loss of the aerosol masking effect, a loss that causes a rise in temperatures, as discussed in an earlier post. Yet, despite pledges by politicians, greenhouse gas concentrations in the atmosphere keep rising, as discussed earlier such as this in this post.

The above image illustrates the danger of two tipping points getting crossed, i.e. the Latent Heat Tipping Point and the Seafloor Methane Tipping Point.

A huge temperature rise thus threatens to unfold over the next few years, as illustrated by the image in the right. Altogether, the rise from pre-industrial to 2026 could be more than 18.44°C, potentially as early as in 2026.
This situation calls for urgent action. Reducing emissions alone won’t be enough. Carbon also needs to be removed from the atmosphere and oceans, through re-/afforestation, through pyrolysis of biowaste with the resulting biochar (and nutrients) returned to the soil and further methods. Even with a rapid transition to clean, renewable energy, with changes to food, land use, construction and waste management, and with removal of large amounts of carbon from the atmosphere and oceans, still more action is needed.
