Reactor 4 of Chernobyl has started to burn again. This is the alarm of the scientists, who are monitoring the situation at the former nuclear power plant in Chernobyl, where nuclear reactions are increasing. Reactor 4 of the nuclear power plant that exploded in 1986 is shaking the scientific community: Ukrainian government scientists are trying to figure out if these reactions will fade on their own or if an intervention will be necessary to avert an accident, even if obviously there is no talk of consequences comparable to what happened 35 years ago but of a much smaller event.
Frosty April 2021 due to the climate crisis
April 2021 was extremely cold due to the climate crisis. According to the European Copernicus program, April 2021 was among the coldest April in since 2003. What happened in Europe, however, did not happen in the rest of the world with generally high average temperatures.
Canada, the Northwest in Russia, Japan and the Middle East had temperatures higher than the average of the period: in France, Italy, Germany and Switzerland the trend was opposite with frosts, cold, snow and almost winter temperatures.
Copernicus report said: "Globally, April 2021 was warmer than any April prior to 2010, but colder than April in 2010 and the months of April in the period from 2016 to 2020. Across Europe, April 2021 was the coldest month when compared to the same period every year since 2003."
These extreme freezing events are a direct consequence of the planet's global warming and climate. Snow accumulations at high altitudes in April are linked to events induced by global warming. Precisely from phenomena that originate in the Arctic, which could be increasingly frequent.
Melting ice in the Arctic raises sea levels and creates slowdowns in the polar jet stream. Melting of ices has accelerated over the past 20 years, and it has contributed to nearly a fifth of sea level rise. Their mapping in HD, published in Nature by an international team led by the University of Toulouse, will allow to improve models on climate change with which to predict future scenarios.
The glaciers present in Alaska and the Andes are the ones that have recorded the greatest losses in the last twenty years, while the Alpine glaciers hold the world record for the reduction of the average thickness, equal to about one meter per year.
Experts said the melting of glaciers involves the loss of important water reservoirs capable of helping agriculture and industry by buffering the scarcity of rainfall in dry periods. Furthermore, the melt water ends up in the seas, which are rising by 3.5 millimeters per year: a problem not only for cities like Venice, but also for the 11% of the world population who live in coastal areas that risk be submerged.
