IPCC issues 'bleakest warning yet' on impacts of climate breakdown

Report says human actions are causing dangerous disruption, and window to secure a liveable future is closingAnalysis: This report asks: what is at stake? In short, everythingClimate breakdown is accelerating rapidly, many of the impacts will be more severe than predicted and there is only a narrow chance left of avoiding its worst ravages, the Intergovernmental Panel on Climate Change (IPCC) has said.Even at current levels, human actions in heating the climate are causing dangerous and widespread disruption, threatening devastation to swathes of the natural world and rendering many areas unliveable, according to the landmark report published on Monday.Everywhere is affected, with no inhabited region escaping dire impacts from rising temperatures and increasingly extreme weather.About half the global population - between 3.3 billion and 3.6 billion people - live in areas "highly vulnerable" to climate change.Millions of people face food and water shortages owing to climate change, even at current levels of heating.Mass die-offs of species, from trees to corals, are already under way.1.5C above pre-industrial levels constitutes a "critical level" beyond which the impacts of the climate crisis accelerate strongly and some become irreversible.Coastal areas around the globe, and small, low-lying islands, face inundation at temperature rises of more than 1.5C.Key ecosystems are losing their ability to absorb carbon dioxide, turning them from carbon sinks to carbon sources.Some countries have agreed to conserve 30% of the Earth's land, but conserving half may be necessary to restore the ability of natural ecosystems to cope with the damage wreaked on them.
