Today, the United Nations Intergovernmental Panel on Climate Change delivered its latest comprehensive report on the state of global climate science—just the sixth in the body’s more than 30-year history. The report’s 200-plus authors distilled 14,000 individual studies to produce today’s release. Even the IPCC’s so-called “summary for policymakers,” a distillation of the report’s key findings approved by the delegations of 195 nations, clocks in at 42 pages.
Here are five key takeaways from the report:
1. The last decade was hotter than any period in 125,000 years.
2. Scientists can now link specific weather events to human-made climate change.
3. Scientists have narrowed the estimated range for how temperatures respond to greenhouse-gas emissions.
4. The Earth rewards good behavior.
5. The IPCC’s volunteer scientists build consensus with all UN governments before releasing this report.
