The goal is to limit the long -term rising of Earth’s temperature below the 2 ° C. Paris Agreement on the climate“He is dead,” warned a prominent American climatic yesterday.

THE James Hansensometimes head of climatologist Nasathis week, a study, research fruit in collaboration with other eighteen scientists, concluding that some of the phenomena that cause climate change are critical.

The analysis of the situation and their predictions show how ‘The target of 2 ° C is dead’Mr Hansen summarized yesterday during her presentation.

One of her most ambitious scenarios Intergovernmental Committee for Climate Change (Giec), made up by the UNpredicted that the decrease in gas emissions that cause the greenhouse effect would probably allow to limit the increase in planet’s temperature below that level; but this ‘It’s impossible today’stressed the climatic.

The reason, he explained, is that energizing on a global scale ‘Increases and will continue to grow’, with ‘Much of this action is still produced with fossil fuels’, which are the main source of emissions of gases that cause the greenhouse effect.

In addition to the fact that the energy transition is over -pace, the team of scientists also found in the study of the study ‘Lack of realism’ In terms of assessing climate conditions, stressing that these latter are much more affected by gas emissions from what is generally accepted.

In their analysis, Mr Hansen and his colleagues took into account the role of changing regulations in the sector sector in 2020, the impact of which they are degraded.

This change has translated into a decrease in the brutal emissions, which reflect sunlight, returning it to space, thus participating in the cooling of the atmosphere.

Researchers also predicted that the Atlantic Ocean (AMOC) meridian reversal, a system of marine currents that play a key role in climate regulation, would stop ‘During the next 20 to 30 years’; because of ice melting.

Their disappearance would cause ‘Major problems’in particular ‘The increase in sea level by several meters’, warned, referring to “Point from which there is no return.”

According to their predictions, average temperatures worldwide will remain equal or upper 1.5 ° C to those of the pre -industrial era in the coming years, before finally reaching the +2 ° C to 2045.

The Paris Agreement, which was adopted ten years ago by almost all countries – and from which Washington announced its upcoming retirementfor the second time – was aimed at increasing the average temperature of the planet to remain ‘Under 2 ° C.’ Compared to pre -industrial levels and continue efforts to limit it to 1.5 ° C.

The aim was to limit the most devastating consequences of climate change and global warming as possible.

The temperature of the world has already increased by 1.3 ° C. World meteorological organization (PMO).
