https://www.vice.com/en_us/article/qj8bem/a-complete-energy-transition-is-needed-by-2030-to-avoid-existential-threat-to-humanity > Scientists backed by the Swiss government warn that widely accepted global scenarios for reducing carbon emissions to avoid dangerous climate change in reality pose a 60-80 percent probability of breaching the 1.5 degrees Celsius (C) ‘safe limit’ agreed by world nations under the 2015 Paris Agreement.   > Their new preprint paper published in March, which is currently under review with the journal Environmental Research Letters, finds that only a “fast and complete” global renewable energy transition led by solar power to be accomplished before 2030 can reduce this probability to a more acceptable level of around 20 percent.
