The U.N. Intergovernmental Panel on Climate Change is scheduled to release its special report on the risks and benefits of limiting global warming to 1.5°C, or 2.7°F, above preindustrial levels.
The report is expected to contain sobering findings of how difficult it will be to meet the 1.5-degree target, which is an aspirational goal contained in the Paris Agreement on Climate Change. Every country in the world — except the U.S. — intends to honor the 2015 agreement, and the report will help inform negotiators in the next round of climate talks, set for December.
- We are currently on track for global warming of between 2.7 to 3.7°C by 2100, according to Kelly Levin, a scientist with the nonpartisan World Resources Institute.
- To meet the 1.5-degree target, we’d need to reach net zero emissions by mid-century, and negative emissions thereafter, using carbon removal tech.
- Current emissions projections show the world is on track to increase emissions through 2030.
Some climate scientists are making clear that the 1.5-degree target, which is seen as low-lying island nations’ best hope for long-term survival, is effectively out of reach.
