The last nine summers have been the hottest in the historical series at a global level and the trend will continue: the UN warns that the next five years will be the warmest ever recorded.
In this context, scientific studies “demonstrate that without the influence of emissions of human origin many of the things that are happening could not happen,” says Jaime Ribalaygua, president of the Climate Research Foundation.
We know that the emission of greenhouse gases into the atmosphere is the main cause of global warming, although it may not be the only one: as explained by Jorge Olcina, director of the Climatology Laboratory at the University of Alicante, “to the anthropic factor is added a natural factor, such as solar radiation itself, which has been more active than normal for two years.
The influence on the climate of the decline in sea ice or the eruption of the Tonga volcano is also being studied. All of this, in any case, implies urgent action, but “we are not on that path,” according to sustainability consultant Jesús Marcos Gamero. As an example, he points out, this year the Climate Summit is being held in Dubai and “is being supervised by the fossil fuel producing countries themselves.”
The Paris Agreement committed in 2015 to limit the temperature increase to one and a half degrees by the end of the century, but Olcina warns that “by 2032-33 we will have reached that degree and a half and the two degrees of the Paris Agreement, indicated as an undesirable limit to reach, we will have reached them in the 2050s”.
However, there is still room for hope, according to Ribalaygua, since “those models that have correctly figured out how the climate has evolved also tell us that, if we really get down to business and reduce the concentration of greenhouse gases in the atmosphere, the impact will eventually be reduced. This is what millions of young people around the world are asking for: a planet on which they can live.
