Why is this summer so hot?

It is hot. Very hot. And we're only in the first few weeks of summer.

Nearly one-third of Americans — more than 113 million people — are under a hot weather warning, the National Weather Service in the United States said. In the US, temperatures are expected to set a new record. In El Paso and Texas, temperatures have been above 37 degrees Celsius for 27 days in a row, surpassing the record set in 1994.

In the United Kingdom, the June heat has not only broken records, but has convincingly exceeded the previous temperatures.

June this year was 0.9 degrees Celsius hotter than in the past. A similar situation is reported in North Africa, the Middle East and Asia. So it was no surprise that June was declared the hottest year on record.

And the hot one hasn't faded. The three hottest days ever were recorded last week, according to the European Union's Climate and Weather Service, Copernicus.

The world average temperature touched 16.89 degrees Celsius on July 3 and exceeded 17 degrees for the first time on July 4, with a global average of 17.04 degrees Celsius.

Then, on July 5, a temperature of 17.05 degrees Celsius was recorded. These temperatures are consistent with climate models that have already been predicted, said Professor Richard Betts, a climate scientist at the University of Exeter.

"We should not be surprised by the high temperatures in the world ", he said.

"This is a reminder that we've been hearing for a long time, and we're going to see even hotter weather until we stop putting more greenhouse gases into the atmosphere."

When we think of how hot it is, we think of the air temperature, because we experience it on a daily basis. However, most of the heat stored on the Earth's surface is not in the atmosphere, but in the oceans. And we've seen ocean temperatures hit record highs this spring and summer. For example, in the North Atlantic, temperatures are currently the highest ever. The US Oceanic and Atmospheric Administration has placed this heat wave in category four. Such a categorization is rarely used outside tropical countries and is considered "extremely hot". The El Nino phenomenon, which is active in the Pacific, is also contributing to this situation.

El Nino is a phenomenon that warms the waters off the coast of South America and then they spread across the oceans.

Nëse uji i deteve është më i nxehtë sesa zakonisht, edhe ju do të përballeni me temperaturë të lartë të ajrit, ka thënë Tim Lendon, profesor për ndryshime klimatike në Universitetin Exeter.

Ai sqaron se pjesa më e madhe e të nxehtit është krijuar nga gazrat serrë dhe është ruajtur nëpër sipërfaqe të oqeaneve.

Ndonëse ai i nxehtë ka tendencë të zhytet brenda në oqeane, fenomene sikurse El Nino, mund ta nxjerrin atë sërish mbi sipërfaqe.

“Kur ndodh diçka e tillë, sasi e madhe e të nxehtit del në atmosferë”, ka thënë profesori Lenton.

Është e lehtë të mendojmë se ky mot tejet i nxehtë është i pazakonshëm, mirëpo e vërteta e dhimbshme është se ndryshimet klimatike nënkuptojnë se tani do të jetë normale që të përballemi me temperatura rekorde.

Greenhouse gases continue to be emitted every year, even with an increasing trend. The hotter the global temperature, the greater the risk of heatwaves, said Friederike Otto, a climate expert at the Grantham Institute for Climate Change.

"These heat waves will not only be more frequent, but also hotter and longer ," she said.

Experts have already predicted that El Nino could make 2023 the hottest year on record. The Earth's temperature has risen by 1.1 degrees Celsius since the start of the industrial age, and temperatures will continue to rise unless governments around the world take steps to curb carbon emissions./ REL
