The world's most authoritative source on climate change, the International Panel on Climate Change (IPCC), has released the most important piece of work on global heating science to date: the Fifth Assessment Synthesis Report.
Integrating all previous work from the IPCC's 26-year history, the 2014 Synthesis Report gives us the most updated scoop on the science of global heating, and the prognosis is not pretty. Global heating will create "severe, pervasive, and irreversible" impacts if countries do not immediately begin to slash greenhouse gas emissions "sharply and rapidly," according to The Guardian. Indeed, this Report presents perhaps the most urgent language the IPCC has ever used to describe the developing situation.
In related news, one study indicates that the IPCC may be underestimating the severity of climate change by avoiding what are called "type 2 errors:" not claiming something is happening when it really is, according to Grist.
