The northern hemisphere suffers from too high temperatures, and climate change is not the only reason, warns the "Guardian".

Last week, the Swedish authorities made an exceptional appeal for international assistance to prevent more and more serious fires throughout the country. the last days. After several months without rain, with high temperatures for weeks, forests across the country have turned into bubbles, writes the British "Guardian".
The results were terrifying. A number of forest fires have escaped and last week more than 50 forests were on fire, many in the Arctic belt. The state known for its cold and snowy weather found itself in an inevitable battle with fires, and was forced to seek international assistance.
As the paper shows, in the northern part of our planet, thermal waves have become commonplace, causing dozens of deaths, fires and droughts. The northern hemisphere, North America, the Arctic, Northern Europe and Africa recorded record highs.
The meteorological station in Algeria in the Sahara recorded a temperature of 51.3 degrees Celsius, the highest temperature ever recorded in Africa.
In Japan, where temperatures reached 40 degrees, people were called upon to take precautionary measures after the death toll reached 30 and thousands of people were accommodated in hospitals. California has increased the use of air conditioners to the extent that there are power shortages.
However, according to the document, the greatest impact of intense heat may have been felt this year in Canada, where temperatures in the 18-day period in Toronto were above 30 degrees.
Moisture Factors
Scientists say that this year Earth has invented factors that are so powerful that they can overcome the power of climate change.
Dozens of people died of the effects of a particularly hot weather. According to media reports, the morgue in Montreal was buried in the bodies of people who died of heat, which caused many of them to be placed in other parts of the city. .
According to the chief medical examiner, Montreal has never had a similar problem so far.
Since the heatwave in Great Britain, the roof of the Glasgow Science Center has sprung up, while meadows have been burned throughout the country.
The current heat wave has become a global problem, says the Guardian.
It remains to be seen why so many localities in the northern hemisphere have been affected by this period.
Most scientists point to a number of factors related to global warming, but others warn that there are more.
Extreme Temperatures
"Some extremely high temperatures have been measured in recent weeks – climate change because it is clearly influenced by other factors," said Michael Mitchell. University of Bristol.
One of these factors is a stream of currents, a core of strong winds eight to 11 kilometers above the surface of the Earth, blowing from west to east and managing weather conditions around the world. Sometimes, when they are intense, these winds bring storms, and when the weak bring in peaceful days, that's what's happening right now.
"The current is currently very low and the result is that areas with high atmospheric pressure are long in the same place," said Michel.
Other factors that create weather conditions and that led to this heat include significant changes in sea surface temperatures in the North Atlantic.
Year Most Affected by Drought
"This is part of a phenomenon known as the Atlantic Multi-Centennial Oscillation, comparable to that of 1976 when we had similar temperatures in the Atlantic.And of course, this year was one of the strongest droughts, the sunniest days and the hottest years of the UK in the twentieth century ", has said Professor Adam Skeif, of the Bureau of Metrology.
However, a key difference between this and 1976, said Professor Tim Ozborn, director of the Climate Research Unit at the University of East Anglia.
"The basis on which these effects are acting today is radically different today: since 1976, we have experienced several decades of global warming due to carbon leakage, which has dramatically increased global temperatures." said Mr Ozborn.
The result is that every phenomenon, such as the current, will have a more pronounced effect than it did 40 years ago. Scientists point out that thermal waves will become more frequent and will deteriorate as carbon emissions increase and the problem is not confined to the earth.
"We also have heatwaves around the world, for example, last year, a sea heat wave hit the Australian coast and devastated the vast expanses of the Great Coral Reef. more and more intense. ", said Michael Borousy of the Ocean Institute in Scotland
