Inside Climate News: Whatever words and phrases the Intergovernmental Panel on Climate Change may have been parsing late into Sunday night, its new report, issued Monday, boils down to yet another dire scientific warning. Greenhouse gas emissions need to peak by 2025 to limit global warming close to 1.5 degrees Celsius (2.7 degrees Fahrenheit), as targeted by the Paris Agreement, the report says.
In a way, it’s a final warning, because at the IPCC’s pace, the world most likely will have burned through its carbon budget by the time the panel releases its next climate mitigation report in about five or six years.
Even with the climate clock so close to a deadline, it’s not surprising that the IPCC struggled to find consensus during the two-week approval session, said Paul Maidowski, an independent Berlin-based climate policy researcher and activist. The mitigation report may be the most challenging of the three climate assessments that are done every five to seven years under the United Nations Framework Convention on Climate Change, he said.
