Temperature rise in the Tropics (update 3)

The temperature in the Tropics (23.5°S-23.5°N, 0-360°E) reached a new record high on April 20, 2024 of 26.913°C (or 80.44°F).

The image below shows the monthly temperature anomaly over the past few years through March 2024, when the anomaly reached a record high of 1.448°C (or 2.606°F).

Note that anomalies in the above image are calculated from 1951-1980 as a base. When calculated from a pre-industrial base, anomalies will be much higher.

The rise in temperature threatens to cause widespread loss of life of people, livestock and wildlife, crop failure and ecosystem collapse in the tropics.

Climate Emergency Declaration

The situation is dire and the precautionary principle calls for rapid, comprehensive and effective action to reduce the damage and to improve the situation, as described in this 2022 post, where needed in combination with a Climate Emergency Declaration, as discussed at this group.

Tragedy set to unfold in Tropics (update)

The temperature in the Tropics (23.5°S-23.5°N, 0-360°E) reached a new record high on March 13, 2024. The image below shows the situation over the years through March 13, 2024, when the average daily surface air temperature was 26.9°C and 1.4°C above 1979-2000 (black line is 2024).

The previous record high temperature was reached on April 24, 2016, when it was 26.8°C, and 1°C above 1979-2000 (grey line is 2016).

The annual maximum temperature in the Tropics is typically reached in April, but very high temperatures were also reached in early May 2023 (orange line is 2023), so the temperature this year may well rise even higher over the next two months.

Meanwhile, we're still in El Niño, according to NOAA and as illustrated by the image on the right.

The image below shows the monthly temperature anomalies over the past few years through February 2024.

Note that the anomalies in the two above images are calculated from different bases. When calculated from a pre-industrial base, anomalies will be higher.

These high temperatures threaten to cause widespread loss of life of people, livestock and wildlife, crop failure and ecosystem collapse in the tropics.

Tragedy set to unfold in tropics

The temperature is rising rapidly in the tropics. The image below shows the situation in the tropics (23.5°S-23.5°N, 0-360°E) through February 14, 2024, when the average daily surface air temperature was 26.3°C, i.e. 1.3°C above 1979-2000.

On April 24, 2016, it was 26.8°C, the highest temperature on record in the tropics, 1°C above 1979-2000, as the above image also shows. The image below shows temperature anomalies over the years.

Note that the above anomalies are calculated from 1979-2000, which isn't pre-industrial. When calculated from a genuinely pre-industrial base, anomalies will be higher. Also have a look at the recent analysis of sponges collected in the Caribbean, illustrated by the image below.

According to NOAA, there is a 100% chance that the current El Niño will persist through February-March-April 2024, as illustrated by the image below.

The danger is that a tragedy will unfold over the next few months as temperatures look set to exceed the 2016 peak in the tropics and cause widespread loss of life of people, livestock and wildlife, crop failure and ecosystem collapse in the tropics.
