World's Hottest Day Recorded Amid El Niño, Carbon Dioxide Emissions

The world's average temperature has peaked on a new high record on July 3 as it reached 17.01 degrees Celsius or 62.62 Fahrenheit.

Citing the US National Centers for Environmental Prediction, a report on BBC said this temperature broke the previous record of 16.92 Celsius that had stood since August 2016.

The report said that the temperature last July 3 was considered as the warmest since scientists had started using satellite monitoring in 1979. Research has shown that it was also the highest since the use of widespread instrumental records started towards the end of the 19th century.

Experts have already warned about the increase of temperature on the land and the sea since the beginning of the year.

Climate scientist Friederike Otto told Reuters that this high temperature should not be celebrated as this would mean "death sentence for people and ecosystems."

El Niño, Carbon Dioxide

Scientists have seen climate change and the occurrence of El Niño as the reason behind the record-high temperature.

"Unfortunately, it promises to only be the first in a series of new records set this year as increasing emissions of [carbon dioxide] and greenhouse gases coupled with a growing El Nino event push temperatures to new highs," Zeke Hausfather, a research scientist at Berkeley Earth, said in the Reuters report.

Earlier, scientists already confirmed that the El Niño has started, which means that additional heat is now welling up to the surface of the Pacific Ocean that makes the global temperature to rise.

They noted that since the phenomenon already started, the public can expect a number of daily, monthly and annual record breaking temperature in the next one and a half year.

Hottest temperatures of countries

According to a report on Al Jazeera, the highest officially registered temperature was 56.7 degree Celsius (134F), which was recorded in California's Death Valley back way back 1913.

Meanwhile, the hottest known temperature in Africa was 55 degrees Celsius (131F), which was recorded in Kebili, Tunisia in 1931.

On the other hand, Iran has recorded Asia's hottest official temperature of 54 degrees Celsius (129F) in 2017.

Records also showed that at least 22 countries have recorded maximum temperatures of 50 degrees Celsius (122F) or above.

Data from NASA has shown that the earth's global average surface temperature in 2020 had tied with the 2016 temperature, which was the warmest year on record.

The past eight years have been the warmest since modern record-keeping started in the 1880s, it added.

The NASA also said that the earth's average surface temperature in 2022 tied with 2015 as the fifth warmest on record.

To measure temperatures, weather stations have been using specialist platinum resistance thermometers placed in shaded instruments, which is known as a Stevenson screen at a height of 1.25-2 meters above the ground.
