Summer 2015 will bid farewell to us tomorrow, Tuesday. Was it the hottest in decades?

ArabiaWeather.com – Tomorrow, Tuesday, September 22nd, will be the last astronomical day of the summer of 2015. This year was distinguished by its thermal extremes and extreme weather events, as it was marked by a remarkable rise in temperatures in most parts of the northern hemisphere.

According to reports issued by NASA and the international meteorological agencies NOAA and JMA, it was found that the summer of this year 2015 was the hottest since the beginning of climate records in the late eighteenth century. And compared to the general average of the globe, the long-term temperatures rose from the general average by about 1.5 degrees Celsius, thus exceeding the average temperatures recorded in 1998 and 2014.

The record temperatures were not only on land, but also in the surface temperature of the oceans and seas, as they recorded a rise above the average, reaching 1.4 degrees Celsius higher than the general long-term average for ocean temperature.

The extreme rise in temperatures was represented in the airspace of all continents. From the continent of Europe, which witnessed a hot and unusual summer, especially in the center and east, where temperatures continued to be more than 7 degrees Celsius higher than their annual general average for a record period of more than two months. East Germany reached 40.3 on August 7. In Geneva, Switzerland, record temperatures reached 39.7 degrees Celsius on July 7, which is about 12 degrees Celsius higher than the general annual average for the summer months.

As for North America, extreme temperatures continued in most parts of it, with a record high temperature exceeding 8 degrees Celsius above the general average for the summer period for several consecutive weeks, especially in the western part of it, which led to the outbreak of forest fires continuously and in large areas.

As for the tropical and humid tropical regions, record high temperatures were recorded. In Venezuela, temperatures reached 43.6 degrees Celsius, which is about 12 degrees Celsius higher than the general average.

In the Middle East, it was a hot summer in every sense of the word, as the average temperature was higher than the average in general, due to the continued high temperatures for long periods. For example, temperatures in northern Kuwait recorded 52.5 degrees Celsius on August 2. The Levant led to successive heat waves, even though it was colder than usual at the beginning.

According to reports, the strong El Nino phenomenon that is currently taking place in the equatorial region of the Pacific Ocean, which is characterized by a rise in the surface temperature of the water in this region, so that the atmosphere is charged with large quantities of high heat, in addition to the effect of increasing the concentration of gases resulting from fossil fuels, which work to record temperatures global standard.
