Circulation of ocean currents, which act as a thermostat on us the planet TF1 Information reports that the effects of global warming are increasing according to a study conducted by a team of Dutch scientists.
Towards the point of no return? In a study published on Friday, February 9, a team of Dutch researchers from the Institute for Marine and Atmospheric Research (Imau) states that the circulation of currents in the Atlantic Ocean is close to a critical shift, thus “Bad news for the climate system and humanity“, reports TF1 information.
To justify their comments, the team relies on the indicator “Early warning“no”Reversal rotation(also called AMOC), a concept that describesThis giant ocean treadmill that redistributes the heat, carbon and nutrients needed for life around Earth
“. Once reaching the Arctic Circle, these currents cool before reaching the ocean depths.Apart from that, using their new data, the researchers were able to confirm that this phenomenon is in the process of decreasing. It may also become irreversible due to accelerated melting of Greenland’s ice sheets and glaciers with global warming.
Fall in 100 years
And the observation is clear. Erosion from this natural process can cause sudden collapse in 100 years. “This is bad news for the climate system and humanity“, point to the experts,”Because until now, we might think that the AMOC shift was just a theoretical concept and that it will disappear as soon as we consider the entire climate system.“
The effects on our ecosystems will then be dramatic and rapid. The level of the Atlantic Ocean could rise by up to a meter in some regions, the seasons in the Amazon would be reversed and the temperature of the land would be completely disrupted. Such sudden changes, it will be almost impossible to adapt to them.
If a study today predicts that the breaking point of this decline is located between 2025 and 2095, the fact is that there is no consensus on the latter extent.
