Rising Temperatures Signal Urgent Action

Global mean surface temperature has risen by 1.2 degrees Celsius, marking the highest in 100,000 years. The recent increase in annual mean temperature has approached 1.5 degrees Celsius in 2023. Concerns arise from an observed acceleration in warming rates: 0.18 degrees Celsius per decade from 1970 to 2010, which escalated to 0.26 degrees per decade after 2014. If this trend continues, exceeding 2 degrees Celsius could occur within the next two decades, with potential to reach 3 degrees Celsius.
