In the Arctic, temperatures are rising faster than in other parts of the Earth, and this process can have negative consequences for the weather on the planet, according to the report of the Climate Crisis Advisory Group (CCAG).
“The Arctic is warming much faster than the global rise in temperatures. Over the past 30 years, the Arctic has warmed 0.81 degrees Celsius per decade - more than three times faster than the world on average (0.23 degrees Celsius per decade)" - noted in the study.
At the same time, the report indicates that the Arctic is not only the fastest warming region in the world, but also probably a "starting point" that has a consistent series of changes on the planet's climate. Experts clarify that the Arctic is one of the 15 most important elements of the "Earth system" that affect the regulation of the climate of the entire planet.
The authors of the report explain that the magnitude of recent floods in Europe and heat waves in North America are difficult to explain based only on a global warming factor of 1.2 degrees Celsius.
“It cannot be ruled out that the rapid warming and melting of ice in the Arctic has provoked additional changes in our weather, and this explains the excessiveness of these extreme (weather events - IF)” the report notes.
The authors pointed out that it is now necessary to understand the impact of several "previously unobserved" phenomena in the Arctic on parts of the planet located to the south.
The chairman of the CCAG British exercise, David King, told Sky news that humanity can cope with such problems, and he has five years to implement the relevant programs.
“And if we do all of this, we have a secure future for humanity that will thrive in the next century” he said.
Sky news notes that King and other scientists, in particular, are exploring the possibility of "re-freezing the Arctic" by creating a cloud cover that will hang over the Arctic Ocean for three months of polar summer. Scientists hope that the cover will reflect the sun's rays, so that the polar ice, which has increased in size over the winter, will persist in the summer.
"If we could repeat this every year for the next 20-30 years, then we could create the ice sheet needed to protect the Arctic Ocean" King added.
