The upcoming El Nino and further events and developments

The upcoming El Niño

The above image shows a forecast for August 2023 of the sea surface temperature anomaly in degrees Celsius, from The forecast shows temperatures that are higher than average (based on 1984-2009 model climatology) for the tropical Pacific region indicative of an El Niño event. 

By contrast, the above forecast for November 2022 shows temperatures in the tropical Pacific region that are much lower than average, indicating that we’re still in the depths of a persistent La Niña. 

By comparison, the above image shows the sea surface temperature anomaly for August 15, 2022, i.e. less than three months ago, when sea surface temperature anomalies in the tropical Pacific region were similar to what they are now, while anomalies in the Arctic were much higher than they are now.

Moving from the bottom of the current La Niña to the peak of a strong El Niño could make a difference of more than half a degree Celsius, as indicated by the image below, adapted from NOAA

The NOAA image on the right confirms that we’re still in the depths of a persistent La Niña. NOAA predicts a transition out of La Niña. Note that the NOAA forecast only goes up to May/June/July 2023. 

The upcoming El Niño looks set to coincide with a peak in sunspots. The peak in sunspots looks set to reach a higher than expected maximum impact around July 2025. An analysis in an earlier post concludes that the rise in sunspots from May 2020 to July 2025 could make a difference of some 0.15°C.
Accordingly, the impact of the upcoming El Niño could make a difference of more than 0.5°C over the next few years. In addition, there will be a growing impact of sunspots, forecast to peak in July 2025. 

Methane keeps rising at accelerating pace

Furthermore, there are a number of events and developments that could additionally speed up the temperature rise, including greenhouse gas emissions that keep rising. Methane is particularly important, due to its high potency as a greenhouse gas, and its abundance has also been growing at accelerating pace over the past few years. 

The above image, adapted from Copernicus, shows a forecast for November 7, 2022, 03 UTC at 500 hPa, with high levels of methane showing up over the Arctic.

The above image shows a peak methane level of 2687 ppb (parts per billion) recorded by the NOAA-20 satellite at 399.1 mb on November 3, 2022 AM.

The above image shows recent methane daily averages at Mauna Loa, Hawaii, ranging from 1900 ppb to nearly 2000 ppb. 

The above image shows recent methane daily averages at Barrow, Alaska, ranging from 2000 ppb to over 2100 ppb. 

Very threatening is a rise in methane that kept following the trend depicted in the above image, created with WMO 2015-2021 global annual surface mean methane abundances, with an added trend that points at a potential mean global abundance of methane of more than 700 ppm (parts per million) CO₂e by the end of 2026. The image warns that, if such a trend kept continuing, the clouds tipping point could be crossed as a result of the forcing of methane alone.  
Further events and developments that could speed up the temperature rise
When including further events and developments, the clouds tipping point could be crossed in a matter of years and even with far less methane than the above trend warns about. 

As an earlier post mentions, the upcoming temperature rise on land on the Northern Hemisphere could be so high that it will cause much traffic, transport and industrial activity to grind to a halt, resulting in a reduction in aerosols that are currently masking the full wrath of global warming.

The post points at a recent analysis that finds a stronger impact than previously thought for liquid water path adjustment, which supports the 2016 warning that by 2026 there could be a 1.9°C temperature rise due to a decrease in cooling aerosols, while there could be additionally be a 0.6°C temperature rise due to an increase in warming aerosols and gases as a result of more biomass and waste burning and forest fires by 2026. 

Furthermore, the 2016 analysis warns about an additional temperature rise of up to 1.6°C due to loss of Arctic sea ice and permafrost, and associated changes.

There could also be additional temperature rises due to increased water vapor, nitrous oxide and further gases. 

When including the temperature rise that has already unfolded from pre-industrial and the impact of all such events and developments, the temperature could rise by more than 10°C over the next few years, corresponding with a CO₂e of over 1200 ppm, which implies that the total temperature rise could be as high as 18.44°C by 2026. 

Keep in mind that humans are likely to go extinct with a rise of 3°C, as illustrated by the image below, from an analysis discussed in an earlier post.

The situation is dire and the right thing to do now is to help avoid or delay the worst from happening, through action as described in the Climate Plan.
