We have a climate emergency, and this report is yet another wake-up call. We must move away from fossil fuels and transition to renewable energy immediately if we are to be able to stay below 1.5°C. Failure to do so will mean confronting tipping points harmful for the entire Earth much faster than expected.
While alarming, accurate long-term predictions are difficult to make, and the numbers here are slightly higher than previous predictions by NASA and the US National Oceanic and Atmospheric Administration. Besides, 1.5°C of warming is only a 20-30 year average, and is by no means irreversible. There's still plenty of time to take action.
Climate and environmental disasters have been predicted by modern-day doomsayers for decades. None of the apocalyptic predictions have come true so far; why would this time be any different?
