At the same time, a growing group of scientists are calling for a serious consideration of the Half Earth idea – where half the planet would be placed under various types of protection in a bid to prevent mass extinction.

Do you support the Half Earth model? What tweaks would you make to it?

Conservation scientists believe our current mass extinction crisis requires a far more ambitious agreement, in the style of the Paris Climate Accord. And they argue that the bill shouldn’t be handed just to nation states, but corporations too.

Let’s be honest, the global community’s response to the rising evidence of mass extinction and ecological degradation has been largely to throw crumbs at it. Where we have acted it’s been in a mostly haphazard and modest way — a protected area here, a conservation program there, a few new laws, and a pinch of funding. The problem is such actions — while laudable and important — in no way match the scope and size of the problem where all markers indicate that life on Earth continues to slide into the dustbin.

But a few scientists are beginning to call for more ambition — much more — and they want to see it enshrined in a new global agreement similar to the Paris Climate Accord. They also say that the bill shouldn’t just fall on nations, but the private sector too.

Oil spill disaster reduced biodiversity in sites closest to spill, report finds, as White House rolls back conservation measures

The 2010 Deepwater Horizon oil spill disaster may have had a lasting impact upon even the smallest organisms in the Gulf of Mexico, scientists have found – amid warnings that the oceans around America are also under fresh assault as a result of environmental policies under Donald Trump.

Lingering oil residues have altered the basic building blocks of life in the ocean by reducing biodiversity in sites closest to the spill, which occurred when a BP drilling rig exploded in April 2010, killing 11 workers and spewing about 4m barrels of oil into the Gulf.

• Rising seas: ‘Florida is about to be wiped off the map’

I spend the afternoon in Shorecrest, a neighborhood a couple of miles north of downtown Miami. To get there I leave the beach behind and drive past Arky’s Live Bait & Tackle, Deal and Discounts II, Rafiul Food Store, Royal Budget Inn, Family Dollar and Goodwill. As I continue north, the buildings all lose their mirrored glass and their extra floors, until most are single story and made from stucco.

South Korea on Thursday released a revised 2030 roadmap for meeting its Paris obligations, scaling back the amount of international carbon credits it plans to buy and instead imposing tougher emission reduction goals on domestic industry.

The UK is falling short in efforts to cut emissions in non-ETS sectors, but should not resort to buying foreign offsets to help meet its binding targets, the country’s climate advisers said Thursday.

Failure to build energy-efficient homes and clean cars risks UK missing its carbon targets, says government’s climate adviser

The homebuilding and carmaking industries “should be ashamed” of their efforts to tackle global warming, according to the UK government’s official climate change adviser.

Lord Deben, chair of the Committee on Climate Change (CCC), said housebuilders were “cheating” buyers with energy-inefficient homes and that motor companies were holding back the rollout of clean cars.
