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. Instead, they only acknowledged the importance of stopping net emissions by mid-century, did not set a timeline for phasing out coal domestically, and weakened commitments to reducing methane emissions. Greta Thunberg called out world leaders for betraying their promises and urged citizens to demand action on the climate crisis immediately. The leaders will be speaking in Glasgow on Monday to address their climate change efforts and potentially make new commitments at the beginning of crucial negotiations. British Prime Minister Boris Johnson will emphasize the urgent need for action, stating that humanity is running out of time to address climate change. If we do not address climate change seriously today, our children will not be able to do so tomorrow. Disagreements among major polluting countries on how to reduce coal, oil, and gas usage and support poorer nations in adapting to global warming will complicate the task. US President Joe Biden criticized China and Russia for not presenting proposals at the Glasgow conference, where they are not sending their leaders. Jinping, the leader of the world's largest greenhouse gas emitter, will deliver a written statement at the conference on Monday. Turkish President Tayyip Erdogan will not be attending the COP26 summit 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. To achieve this goal, more ambitious emissions reduction pledges, climate financing for developing countries, and finalizing rules for the Paris Agreement are needed. Without stronger commitments, the planet's average surface temperature is projected to rise by 2.7 degrees Celsius, worsening the destructive impacts of climate change. Ugandan activist Evelyn Acham stated in an interview with Italian newspaper La Stampa that Africa, despite being responsible for only 3 percent of global emissions, is bearing the brunt of the most severe consequences of the climate crisis. She emphasized that Africans are not to blame for the crisis, but are still suffering due to the historical exploitation of Africa's resources during colonial times. Acham called for a 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 conclusion on November 12.
