In a warming world, this country is experiencing increasingly intense cold snaps!

There is a country in the world that is becoming colder and snowier, bucking the trend of global warming: Mongolia. In fact, this country has been suffering extremely harsh winters for about twenty years and all forecasts estimate that the phenomenon will continue to worsen, going against the grain of what is happening in other places in terms of climate.

This region of the world never makes the headlines, and yet Mongolia just suffered an extreme winter, not in terms of heatheat Like many countries in the world, but in terms of cold: around 90% of Mongolia experienced exceptionally cold and snowy conditions this winter. More than 2 million cattle have died from the cold in recent months. This is “dzud”, a term that designates a frozen and abnormally snowy climate, which causes the mortality of massmass in animals and sometimes also in humans.

The phenomenon is not new and occurs on average once every 10 years in Mongolia. But in recent years this has happened much more frequently: the country has just experienced a catastrophic dzud two winters in a row. Temperatures often dropped to -45°C. Unlike most countries in the world, winters are becoming harsher in Mongolia, with drops inairair Arctic more frequent and above all longer lasting.

Climate blockages caused by weakening jet stream

Not only do extremely cold days increase, but also dry periods, but also during the summer. Local populations have also observed that the harshest winters follow dry summers, which has already weakened livestock. But where does this surprising climate change come from? The phenomenon is still not well understood and many questions remain, but there would be a direct link to the weakening of the jet stream caused by global warming: the more the jet stream weakens, the more it undulates and the loops it forms trap the dry climate in summer or the cold air coming from the poles in winter, and this for many weeks.

The phenomenon will continue to worsen in the coming years

According to Yale University, extreme cold days were 28% more frequent between 2000 and 2016 than between 1981 and 1999. Snow has also increased 40% since 1961. This layer of snow on the ground also amplifies the risk of extreme cold, further cooling the atmosphere. And this phenomenon will not decrease in the future, according to forecasts. climatologistsclimatologists : The IPCC predicts a 20% increase in dzuds by 2080, with the consequence: “ inevitably a very high livestock mortality”.
