2018/10/04: World greenhouse gas emissions must peak by 2020 - just 15 months from now.
According to a U.N. preview of the report, meeting the 1.5 goal would “require very fast changes in electricity production, transport, construction, agriculture and industry” worldwide, in a globally coordinated effort to bring about a zero-carbon economy as quickly as possible. It would also very likely require eventually removing huge amounts of carbon dioxide from the atmosphere using technology that is not currently available at the scale that would be necessary. And there’s no time to waste: “The longer CO2 is emitted at today’s rate, the faster this decarbonization will need to be.”
The world has already warmed by about 1.1 degrees C, and the implications of that are increasingly obvious. In just the three years since the Paris Agreement was signed, we’ve seen thousand-year rainstorms by the dozens, the most destructive hurricane season in U.S. history, disastrous fires on almost every continent, and an unprecedented coral bleaching episode that affected 70 percent of the world’s reefs.
In this age of rapid warming, the IPCC report is inherently political — there are obvious winners and losers if the world fails to meet the 1.5-degree goal. If the world’s governments are to take the implications of IPCC’s findings seriously, it would be nothing less than revolutionary — a radical restructuring of human society on our planet.
