While everyone is busy with daily chores, the climate onthe planet is rapidly deteriorating. The temperature rises every year, and the consequences of its change negatively affect the state of wildlife. Climatologists are worried about record temperatures in the Arctic, which heats twice as fast as the rest of the planet, creating ecological chaos for plants and animals. As the results of scientific research have shown, over the past five years, the air temperature in the Arctic has been higher than in any period since 1900. Thus, climate change in the Arctic can influence the occurrence of extreme weather conditions around the world.
What is happening in the Arctic?
There are topics that no one likesspeak. But is it any wonder that not everyone wants to listen to gloomy forecasts of scientists, some of which predict no more than 100 years of life for humanity. The reality, however, is that scientists have bad news for us. So, residents of the Russian city of Verkhoyansk celebrated the first day of summer with a temperature of + 37ºC. It’s not that they didn’t like it, because Verkhoyansk is located in Siberia, hundreds of kilometers from the nearest beach, it’s just much, much warmer than usually in cities beyond the Arctic Circle. Apparently, on June 1, a new temperature record was recorded.
Another disturbing factor is abnormalthe heat in Siberia, which, according to researchers, is associated with forest fires, the invasion of the Siberian silkworm and rising temperatures. I talked in more detail in the previous article.
According to the publication Wired, all the events of recent weeks are unprecedented in terms of extreme temperatures. Extreme warming in the Arctic, known as arctic gain or polar amplification, can be caused by three factors:
- Firstly, surface reflectivity (amountthe light that it throws back into space) changes as the planet heats up. Since the ice is white, it reflects the sun's rays, which allows it to remain cold in the summer. If the ice in the Arctic melts, then the white surface of the ocean will disappear. In turn, a darker surface will absorb more solar heat, which will warm the region's waters and potentially cause a rise in land temperature.
- Secondly, this is consistent with the change in currents. Ocean currents usually bring warmer water from the Pacific Ocean, while colder water flows from the Arctic to the Atlantic. But these currents can change, as thawed ice fills the Arctic Ocean with fresh water, the density of which is less than the density of salt water.
- ThirdlyThe lack of ice also strengthens the wind bysurface, accelerating the Beaufort cycle, which traps water, usually discharged into the Atlantic. This acceleration mixes colder fresh water on the surface and warmer salt water below, raising the surface temperature and further melting the ice.
What do you think about climate change and the rapid melting of Arctic ice? We will wait for the answer here!
The world is getting warmer, the weather is getting worse. That's all there is to know about what people can do to stop the destruction of the planet. Ocean currents affect the weather, setting in motion a powerful polar jet stream that moves hot and cold air masses around the Northern Hemisphere. This is the result of temperature differences between the Arctic and the tropics. But as the Arctic warms up, the jet stream fluctuates between north and south. The presence of warm air over the Arctic during the summer even more threatens sea ice and permafrost.
Myers-Smith, an environmentalist at the University of Edinburgh.
Melting permafrost - underground ice penetrating deep intohundreds of meters and existing for a long time - can change the salinity and overall chemical composition of the water flowing through the Arctic. Scientists note that the northern soil contains huge reserves of frozen mercury. The question of whether this mercury can move downstream, get into the water and poison fish, which will then affect local residents and agriculture, remains open.
This is interesting: Humanity may disappear due to the extinction of insects.
Researchers recently discovered that part of permafrost is melting so quickly that it collapses, cutting huge holes in the landscape. This phenomenon known as thermokarst - the process of uneven subsidence of soils andunderlying rocks. The result is a swamp, not solid soil, which affects the mobility of both humans and animals. Reindeer husbandry is widespread in a large part of the Arctic, which will be destroyed if the Earth loses its hardness.
It’s important to understand that everything that happens today inthe world - whether it be forest fires, rising temperatures, the spread of dangerous diseases and rising sea levels - are the consequences of rapid climate change caused by human activities. If humanity does not rethink the way of modern life and does not revise its habits, the consequences of global warming will be catastrophic.
