Title: World on Track for 2.8C Warming as US Emissions Rise
Content: The world is headed toward a long-term temperature rise of 2.8C based on current government policies, according to the latest UN report. The US stands out among developed economies with sharply higher energy-related emissions, driven by a coal generation rebound under President Donald Trump's policies to meet increased power demand. Global greenhouse gas emissions declined slightly last year, but the change was not sustained enough to indicate a long-term plateau. The UN confirmed that limiting warming to 1.5C above pre-industrial levels is no longer possible, though an overshoot could potentially be reversed by century's end. Returning to below 1.5C would require emission cuts of 45 percent by 2035, nearly triple the 11 to 15 percent outlined in current national plans. The report noted significant socio-economic and technological challenges facing permanent carbon dioxide removal techniques. More promisingly, renewable electricity capacity and solar panel deployment have grown faster than expected since the Paris Agreement. UN Secretary-General Antonio Guterres warned that every year of delay makes the path back steeper, noting overshoot is not surrender. The outlook under existing policies was unchanged from the previous report, while forecasts based on conditional or unconditional plans have worsened. Following the US's decision to quit the Paris Agreement, new national climate targets since last year had a near-zero impact on expected emissions and warming.
FAQ Q: What would it take to return global warming to below 1.5C?
FAQ A: Emission cuts of 45 percent by 2035 and an increase in permanent CO2 removals through techniques facing significant socio-economic and technological challenges.
