UN-IPCC scientists have unveiled an urgent plan that can limit the causes of dangerous climate change.
First, the bad news - even with all current policies to cut carbon in place, we still face a 3.2C rise this century and our planet will suffer "unprecedented heatwaves, terrifying storms, and widespread water shortages".
The good news (maybe) - The IPCC summary shows it can be done, in what UN Sec-Gen Guterres calls a "viable and financially sound manner" - but requiring massive changes to energy production, industry, transport, our consumption patterns and the way we treat nature.
