The Copernicus Climate Change Service (C3S) data reveals 22 July was the hottest day. At 17.16°C,  on 22 July 2024, the daily global average temperature reached a new record high. In the ERA5 dataset, previous records was of 17.09°C. The ERA5 dataset began recording in 1940. Copernicus is the European climate change service.

The recorded temperature by C3S  on 21 July 2024  was 17.09ºC and on 22 July the new record temperature reached 17.16°C.

As per the report, this disparity is larger than typical differences in day-to-day variations among alternative datasets.

As per the database, the previous daily global average temperature record was on  13 August 2016 (16.8°C). From 3 July 2023  to 23 July 2024, there have been 59 days that have exceeded that previous record(16.8°C).

The ten years with the highest annual maximum daily average temperatures are the last ten years, from 2015 to 2024.

The report sees it as another sign of the global warming trend.

REASONS FOR TEMPERATURE RISE

Generally during the northern hemisphere summer, the global average temperature(GAT) tends to reach its annual peak. The corresponding months for the rise in temperature is between late June and early August. The reason for this is because the large land masses of the northern hemisphere warm up faster.

One of the analysis suggests that the sudden rise in daily GAT is related to much above-average temperatures over large parts of Antarctica.

Moreover, the antarctic sea ice extent is almost as low as it was at this time last year, leading to much above-average temperatures over parts of the Southern Ocean.

This is  also  partly due to an El Niño – which typically brings hotter-than-average temperatures

The 1.5°C warming threshold, one of the important goals of the Paris Agreement for long-term average of temperatures, was breached every day from July 18 to July 23. T

he year 2023 was the hottest in modern records. The World Meteorological Organization (WMO) also reported(Dec 2023) 2011 to 2020 being the warmest decade on record.

As the climate keeps warming, we are bound to see new records being broken in future months and years.
