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 closing

Climate 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.

“The scientific evidence is unequivocal: climate change is a threat to human wellbeing and the health of the planet,” said Hans-Otto Pörtner, a co-chair of working group 2 of the IPCC. “Any further delay in concerted global action will miss a brief and rapidly closing window to secure a liveable future.”

Droughts, floods, heatwaves
In what some scientists termed “the bleakest warning yet”, the summary report from the global authority on climate science says droughts, floods, heatwaves and other extreme weather are accelerating and wreaking increasing damage.

Allowing global temperatures to increase by more than 1.5C above pre-industrial levels, as looks likely on current trends in greenhouse gas emissions, would result in some “irreversible” impacts. These include the melting of ice caps and glaciers, and a cascading effect whereby wildfires, the die-off of trees, the drying of peatlands and the thawing of permafrost release additional carbon emissions, amplifying the warming further. 

Oh dear Australia the the home of Drought, fire and flooding rains.

And Australia is still a carbon sink. Saving the rest of the world from itself.
