Rosario is expected to record very high temperatures in summer

Europe’s position regarding high temperatures reinforces the question of what is going to happen in this part of the world when summer arrives. one in In the context of continued emissions of polluting gases that contribute to global warming, various experts explain that this part of the world has advantages compared to the Northern Hemisphere. However, they also confirm that although several day-long events are not expected to occur in Europe, they estimate that it will be necessary to use for two events: high temperatures and the historical maximum that developed over a shorter period. Will be In connection with the calculations of the end of the last century.

las heat waves in europe From early July, to the point that more than 40 degrees were recorded in England for the first time in history, around London Heathrow Airport (the previous historical mark, 38.7 degrees, occurred on July 25, 2019 in the City of Cambridge). Meanwhile, Portugal this week moved closer to the European record of 48.8 degrees, which was recorded in Sicily last year., Spain and France also recorded temperatures above 40 degrees for several days.

According to warnings by the World Meteorological Organization (WMO), these values ​​will be more and more frequent and will continue “at least until 2060”., According to scientists, the increase in the frequency of heat waves recorded in Europe comes as a direct result of the climate crisis, as greenhouse gas emissions increase their intensity, duration and frequency.

There are some advantages in this part of the worldas wide as Capital Irene Vice, a biologist and professor at the University of Buenos Aires (UBA), specialized in ecology and environmental impact assessment: “The Earth has an uneven distribution of continents, There is more land than water in the Northern Hemisphere and vice versa in the Southern Hemisphere. and oceans are climate moderatorsWith them, researchers from the National University of rosario (UNR), Emiliano Jozami contributed: “It is For what happens in Europe, it’s more difficult here because we have less continental and the advantage of the calming power (of temperature) that the sea has”.

In any case, he warned that “we have to”. get used to the fact that we’re going to have higher temperatures“And that The maximum temperature period, which was previously estimated every 20 years at the end of the 20th century, is now estimated to occur every five years., “Extreme temperatures and heat waves are going to be more and more frequent,” said he, who in turn is a professor of agricultural climatology at UNR and the National University of Villa María. The estimates come from the study “Managing the Risks of Extreme Weather Events and Disasters to Improve Climate Change Adaptation” by the Intergovernmental Panel on Climate Change (IPCC, for its abbreviation in English).

Best in the Southern Hemisphere

The answer to the question whether one should expect temperatures similar to those of last summer, when thermal sensations exceed 40 degrees even at night, is yes. In any case, The contrast with the situation passing through these weeks in the Northern Hemisphere focuses on the higher demographic concentration that is present in Europe, which occurs in the southern cone.,

In this regard, Vays explained: “The south of Brazil, Argentina, Chile and Uruguay have more widely spaced demographics than those in Europe, where populations associated with the Mediterranean are more advantageous than those located in Central Europe. , above all, after all, they don’t have an aquatic environment nearby.”

,We’re going to have higher temperatures, but the northern hemisphere is the one that’s going to suffer the most, because luckily, we have a lot of oceans.Jojami added.

short-term intense heat

biologists estimate that during the summer “It is likely that we will have two or three days in a row of high temperatures, just like last year. But there are different types of winds that help generate cold fronts. In Europe they have been like this for 20 days, here it is not likely to happen. But because of the dire situation we’re going through, it’s going to be hotter than before.”,

Have referral from specialist Global warming, in present No concrete decision by nations to accelerate mitigation Following the same, what was the United Nations Conference on Climate Change in Glasgow last year, in which an agreement was signed, although it ratified the conditions set out in the Paris Agreement in 2016, “many Issues remain unresolved and commitments remain insufficiently ambitious enough to reach the goal of preventing a 1.5 degree increase in Earth’s average temperature”, according to the United Nations.

This factor has been linked with that although There was a slowdown in pollution levels during the pandemic as a result of movement restrictions, which do not necessarily decrease the pre-existing layer.Known as the greenhouse effect.
