Part 7/12:
Although recent forecasts initially warned of a 4° C temperature rise, current actions suggest a more optimistic outcome of 2.2 to 3.4° C, with a median estimate of 2.7° C by 2100 based on government policies. This implies a significant reduction in emissions, particularly in advanced economies, which have returned to emission levels not seen in half a century. However, a 2.7° C rise still presents grave threats to wildlife, agriculture, and public health.
