"On the eve of COP26 in Glasgow, all roads to success go through Rome," UN Secretary General Antonio Guterres toldreporters on Friday. Known as COP26, it is seen as vital to addressing the threat ofrising temperatures and consequences like rising sea levels,more powerful storms, worse flooding in some regions and worse droughts in others. Many of the leaders in Rome, including US President Joe Biden, will fly immediately afterwards to Scotland for a United Nation's climate summit. The G20 bloc, which includes Brazil, China, India, Germany and the United States, accounts for more than 80% of the world's gross domestic product, 60% of its population and an estimated80% of carbon emissions. The health crisis and economic recovery feature strongly on the agenda, but the most vital and difficult debate will centre on how far the leaders want to go in cutting greenhouse gases and in helping poorer nations confront global warming. It is the first time in two years that most leaders of the G20 have felt able to hold face-to-face discussions as the Covid-19 pandemic starts to recede in many countries. "You saw that with the decline and fall of the Roman Empire and I’m afraid to say it’s true today." "There is absolutely no question that this is a reality we must face up to," he told reporters as he flew into Rome for the G20 summit, warning that living conditions could rapidly deteriorate without a collective change of course. Speaking just hours before leaders of the group of 20 major economies start a two-day meeting in Italy, Johnson said future generations risked hunger, conflict and mass migration if progress was not made to tackle climate change.
Global leaders must step up the fight against climate change, British Prime Minister Boris Johnson warned on Friday, saying world civilisation could collapse as swiftly as the ancient Roman empire unless more is done.
