UN said 2021 is the decisive year to fight the climate crisis

United Nations Secretary-General Antonio Guterres, speaking of the new report presented by the United Nations Framework Convention on Climate Change, said: "2021 is a decisive year to address the global climate emergency.

The science is clear: to limit the increase global temperature to 1.5 degrees Celsius, we need to reduce global emissions by 45% by 2030 from 2010 levels. It is a red alert for our Planet, governments are nowhere near the level of ambition needed to limit climate change to 1.5 degrees and meet the Paris Agreement goals.

Major emitting countries need to step up their emissions reduction targets for 2030. This must take place before the United Nations Climate Conference in November in Glasgow. The time is now. Recovery plans to overcome the Covid-19 emergency offer the opportunity to rebuild an environment you greener and cleaner.

Long-term commitments must be accompanied by immediate action." Most nations have increased their commitment levels to reduce emissions. But the combined effect would lead to a reduction of less than 1% by 2030 compared to 2010 levels.

The reduction of emissions to reach the goal of 1.5 degrees should be below 45%.

Europe with drier summers due to the climate crisis

Europe with drier summers due to the climate crisis. The study, published in Science Bullettin and led by Nikos Christidis and Peter Scott, highlights the consequences of climate change in Europe.

The study explains: "We expect to see significant changes to European summers as a consequence of human-induced climate change. Summers could become much drier and this change will become more and more evident as we move towards the end of the century."

The researchers analyzed the historical trends on the summers of the Old Continent and, using a predictive model with medium emissions for the next decades, they estimated the probability of summers characterized by rain or drought.

Furthermore, they also added to their model the variables relating to the increase in temperature and changes in evapotranspiration. Global warming in Europe is already a reality and, without specific interventions, will continue to worsen over the coming decades.

So much so that, by the end of the century, summer rains will become a real rarity across the continent, resulting in seasons extremely affected by drought and heat. Since summer seasons plus tower do not mean the absence of water.

Indeed, the correspond to the increase in dangerous atmospheric phenomena, such as storms, floods, floods and hurricanes. This was explained by Kate Willet, an expert at the Met Office, underlining that the more water is retained in the atmosphere in the form of gas due to evaporation due to the increase in temperatures, the greater the possibility of extreme precipitation.

Climate change will lead to increasingly dry and hot summers across Europe. This is what emerges from a new study, conducted by the Hadley Center of the British Met Office, on the consequences of climate change for the Old Continent.

Not only worries about the occurrence of hot seasons ready to bring temperatures typical of areas close to deserts to Europe, but also the fact that the model has been developed on estimates of average emissions. In other words, with containment measures in the production of greenhouse gases already implemented.
