Global warming and pollution caused by humanity's carbon-heavy footprint are ravaging Earth's oceans and icy regions in ways that could unleash misery on a global scale, a landmark UN report to be unveiled next week will warn.
The underlying 900-page scientific report from the Intergovernmental Panel on Climate Change (IPCC) is the fourth such UN tome in less than a year, with others focused on a 1.5-Celsius cap on global warming, the decline of biodiversity, as well as land use and the global food system.
All four conclude that humanity must overhaul how it produces, distributes and consumes almost everything to avoid the worst ravages of global warming and environmental degradation.
