Last year was second-warmest and decade was hottest ever: UN
UN Secretary-General Antonio Guterres, said: “Greenhouse gas concentrations are at the highest levels in 3 million years – when the Earth’s temperature was as much as three degrees hotter and sea levels some 15 metres higher.”
He added: “Ocean heat is at a record level, with temperatures rising at the equivalent of five Hiroshima bombs a second.”
Taalas said the warming of the oceans has led to unusual tropical storms, including one in Mozambique in March 2019 that was the strongest in the Southern Hemisphere “at least for the past hundred years.”
He said there is also an estimate “that sea water is the most acid in 25 million years … and that’s going to have negative impacts on the sea ecosystems.”
