Climate change | July 2023 is the hottest in the history of climate records, and June 2024 records temperatures higher than normal globally.

Arabia Weather - In a previous report issued by the World Meteorological Organization in conjunction with the Copernicus Climate Change Monitoring Service on the climate situation that prevailed in the world during the month of July 2023, this month was considered the hottest in the history of climate records due to climate change that continued to grow until the July record. 2023 Record temperatures and higher than usual.

Due to climate change: July 2023 is the hottest month on record

According to European Center data from the Copernicus service, July 2023 was the hottest month ever in the history of climate records, as large parts of North America, Asia and Southern Europe were exposed to severe heat waves, which led to the outbreak of forest fires in many countries such as Canada, Greece and Algeria.

The world witnessed the hottest day ever recorded on July 6, which broke the global average temperature record set in 2016. The average global temperature rose above 17 degrees Celsius for the first time, reaching 17.08 degrees Celsius.

Highest average monthly global temperature in July 2023

As a result of climate change, the average global surface air temperature in the first 23 days of July reached 16.95 degrees Celsius, surpassing the record of 16.63 degrees Celsius recorded for the entire month of July 2019, which is currently the warmest July on record. Data will likely later show that the full monthly average temperature for July 2023 will exceed the average temperature of July 2019 by a large margin, making July 2023 the warmest July and the warmest month on record in the history of climate records.

Average daily sea surface temperatures over the oceans over the range (60°S - 60°N) have remained at record values ​​for this time of year since April 2023, as global sea surface temperatures rose to unprecedented levels for this time of year, reaching The value (mean daily sea surface temperatures) reached 20.94 °C, which is 0.01 °C from the highest value recorded on March 29, 2016 (20.95 °C).

The Mediterranean Sea is in the crosshairs of climate change

Arab weather experts said that this increase was also noticeable in the Mediterranean basin during the year 2023, as the countries of the central and western Mediterranean were affected by heat waves during the past weeks, causing the temperature of the Mediterranean surface to rise above its usual levels by more than 4-6 degrees. Degrees Celsius, especially in the western part of it.

June 2024 will record higher than normal temperatures globally

According to the National Atmospheric and Oceanic Agency, temperatures in June 2024 were above average across most of the Earth's surface except western Canada, most of Greenland, southern South America, northwestern Russia, eastern Asia, eastern Australia, and most of East Antarctica. Africa, Asia and South America recorded their highest June temperatures on record, while Europe recorded the second highest temperatures. Sea surface temperatures were above average in most areas, while parts of the eastern tropical Pacific and southeastern Pacific were below average. Global oceans have been record warm since April 2023.

The lower layer of the atmosphere was not insulated from the high temperatures

Temperatures in the troposphere, the layer of the Earth's atmosphere closest to the Earth's surface (2 to 6 miles above the Earth's surface), rose at a record high in June, according to satellite data from NESDIS. Each of the past 12 months has set world records for the middle troposphere.

Snow cover and sea ice are declining due to climate change

The extent of snow cover in the Northern Hemisphere in June was the 12th smallest on record, the NOAA report said. Both Eurasia and North America were below average (by 310,000 and 290,000 square miles, respectively). Overall, snow cover was below average in most areas except for parts of western Siberia, small parts of China and Pakistan, and far western Canada, which were above average.
