It's main highlight - global warming must be limited to 1.5°C rather than the previously agreed 2°C to avoid extreme heat, drought, floods and poverty around the world. This is especially alarming given that US (one of the major contributor to annual CO2 emissions) withdrew from Paris agreement in July 2017.
Also, according to the report, following present trends the 1.5°C cap could be reached as early as 2030. It has been estimated that CO2 emissions would have to drop by 45 percent from 2010 levels by 2030.
Needless to say, these difficult targets can't be met without cooperation between governments and technological innovations.
