Signal 1.5 degrees of warming likely reached in the early 2030s

Summary

The report states that unless emissions fall quickly, global warming is likely to hit 1.5 degrees Celsius in the early 2030s. That threshold is measured as an average temperature across several decades. Average global surface temperatures have already climbed about 1.3 degrees above pre-industrial levels, and the past ten years were the warmest on record. The report holds that floods, heatwaves and droughts become more common with each further increment of warming. The Climate Change Committee and the House of Lords have both cautioned that weak planning and maladaptation in Britain might make these outcomes worse. The report adds that unplanned recovery and repair costs exceed the cost of adapting in advance.
