Although the temperature in the northern hemisphere was colder than it had been for the past 30 years, it was higher than average in the Arctic. And this is important because the Arctic climate is known to affect the entire planet.
This winter season the maximum ice was reached in this area. The thaw begins every March and lasts until September. We are all concerned that global warming is still twice that of other parts of the world.
What is Arctic Reinforcement?
Known as Arctic fortification, the phenomenon is, to a greater extent, the cause of the loss of albedo. This measurement indicates the reflectivity. Even with less ice and snow, the albedo is high and the sun’s heat penetrates deeper and melts it faster.
Given that the polar helmets act as refrigerators for the planet in both the north and south, the problem is more than worrying. It’s like having no air conditioning in a very hot and unventilated place.
Consequences of this phenomenon
The Arctic zone lost more than 200 million tons of sea ice from 1980 to the present day due to the gradual rise in temperature in the air. Sea water, which is much darker than ice or snow, absorbs heat and prevents thicker ice from forming in winter.
The continental zone does not escape the problem as it melts faster due to the thinness of the ice. When the permafrost melts, wells are formed that release large amounts of greenhouse gases such as methane into the atmosphere.
The albedo concern has also reached Greenland, where snow and ice are darkening. This darkening is due to large forest fires and causes snow and ice to melt faster.
As if that weren’t enough, the sun warms the rocks where there was previously ice, and the phosphorus it contains encourages algae to multiply. These algae avoid the formation of ice in winter when they reproduce. According to NASA, the oceans would rise 7 meters if the Greenland ice were to melt completely.
According to the World Meteorological Organization, we are experiencing new climate norms that differ greatly from those that are common worldwide. Changes in average temperature, precipitation level or persistent snowfall among others.
The Arctic thaw began in March 2021 and is known to affect ocean currents, rainfall, and climate in general. In addition, devastating forest fires as a result of climate change have been observed around the world in recent years.
