This report spells out what the world would be like if it warmed by 4 degrees Celsius, which is what scientists are nearly unanimously predicting by the end of the century, without serious policy changes. It provides a snapshot of recent scientific literature and new analyses of likely impacts and risks that would be associated with a 4° Celsius warming within this century, ranging from sea-level rise to increases in tropical cyclone intensity, unprecedented heat waves, severe drought, and major floods in many regions, with serious impacts on ecosystems and associated services.
