The Hope At The Heart Of The Apocalyptic Climate Change Report
When the Intergovernmental Panel on Climate Change (IPCC) published a new special report last week, it came with both good news and bad. The good news is that the carbon budget for staying under 1.5 degrees Celsius of warming is larger than we thought, so we have a bit more time to act. The bad news is that the consequences of overshooting that threshold are very, very bad. The catastrophes that we once believed would be triggered by only 2 degrees of warming are likely to occur at this lower threshold, including widespread collapse of food yields and extreme levels of human displacement. The IPCC has issued a clear and trenchant call for action—its most urgent yet. It says we need to cut annual global emissions by half in the next 12 years and hit net zero by the middle of the century.
