Australian pumped hydro project proposals tend not to be located at premium sites, which translates to higher costs. A new paper explains.

In a high emissions future, the world’s strongest ocean current could slow down by 20% by 2050, further accelerating Antarctic ice sheet melting and sea level rise, an Australian-led study has found.

The Antarctic Circumpolar Current – a clockwise current more than four times stronger than the Gulf Stream that links the Atlantic, Pacific and Indian oceans – plays a critical role in the climate system by influencing the uptake of heat and carbon dioxide in the ocean and preventing warmer waters from reaching Antarctica.

Bold pledges to fund climate projects now appear under threat, exposing deeper fiscal constraints and policy dilemmas within the government

In October, the prime minister, chancellor and energy secretary pledged billions to kickstart the UK’s first carbon capture projects – one of the biggest green spending promises of the parliament. By December, Ed Miliband was signing contracts, Sir Keir Starmer vowed to “reignite our industrial heartlands” and Rachel Reeves warned that without bold action, Britain would be stuck with low growth and falling living standards. More importantly, net zero targets wouldn’t be met without removing carbon dioxide from the atmosphere.

Fast forward and the Treasury is, reportedly, preparing to scrap the £22bn plan, after economic growth failed to materialise. What a difference a few weeks make.
