The COP26 conference in Glasgow began after the G20 nations failed to agree on a 2050 target to stop net carbon emissions, which is seen as crucial in preventing severe global warming. During talks in Rome, they only acknowledged the importance of halting emissions by mid-century, did not set a timeline for phasing out coal domestically, and weakened commitments to reducing methane emissions, a potent greenhouse gas. Greta Thunberg urged her followers to sign a letter accusing leaders of betrayal and called for immediate action on the climate crisis. In Glasgow on Monday, many leaders will speak about their climate change efforts and make new promises at the start of crucial negotiations. British Prime Minister Boris Johnson will emphasize the urgent need for action, stating that humanity must act now as time is running out. If we do not take immediate action on climate change, our future generations will not have the opportunity to do so later. However, disagreements among major emitters on how to reduce coal, oil, and gas emissions and support developing countries in adapting to global warming will only make the task more difficult. US President Joe Biden criticized China and Russia for not presenting proposals to address climate change at the G20 summit. Chinese President Xi Jinping, the largest emitter of greenhouse gases, will provide a written statement at the conference on Monday. Turkish President Tayyip Erdogan will not be attending the COP26 conference in Glasgow due to Britain's failure to meet Ankara's security and protocol demands. The conference, delayed by a year because of the COVID-19 pandemic, aims to limit global warming to 1.5 degrees Celsius above pre-industrial levels. This goal requires more ambitious emissions reduction pledges, increased climate financing for developing countries, and finalizing the rules for the 2015 Paris Agreement. Current emissions reduction commitments would result in a temperature increase of 2.7 degrees Celsius, which the United Nations warns would exacerbate the destructive effects of climate change. "Africa may only account for 3 percent of global emissions, but its people are bearing the brunt of the climate crisis," stated Ugandan activist Evelyn Acham in an interview with the Italian newspaper La Stampa. She emphasized that Africans are not to blame for the crisis, as they have suffered the consequences of colonialism that exploited the continent's resources for many years. Acham stressed the importance of fair distribution of responsibilities. Following two days of speeches by world leaders beginning on Monday, technical negotiations will take place. It is possible that a deal may not be reached until close to or even after the event's November 12 conclusion.
