MILAN, ITALY: Greta Thunberg led criticisms at climate talks in Italy, saying much has been promised but little done to tackle global warming in 30 years since the landmark Earth Summit.
A report by the United Nations (UN) cited concerns about the climate change issues, citing that it might be spiraling out of control.
Along with Thunberg young activists have converged on Milan with some 400, from about 190 countries, due to engaging with policymakers.
"There is no planet B...Change is not only possible but necessary, but not if we go on as we have until today," said Thunberg at the opening session of a Youth4Climate event.
UN COP26 conference will be held this year in November. Their aim is to secure more ambitious action from the nearly 200 countries that signed the 2015 Paris Agreement.
