Could a new kind of carbon budget ensure top emitters pay their dues?

Some researchers propose that countries should start to rack up a carbon debt once they exceed their carbon budget, obliging them to do more to draw down carbon dioxide, but the idea is unlikely to form part of international climate agreements ​Some researchers propose that countries should start to rack up a carbon debt once …

Quantum computers are on track to solve knotty mathematical problems

A quantum algorithm for solving mathematical problems related to knots could give us the first example of a quantum computer tackling a genuinely useful problem that would otherwise be impossible for a classical computer ​A quantum algorithm for solving mathematical problems related to knots could give us the first example of a quantum computer tackling …

Flourishing microalgae could offset emissions as the planet heats up

Photosynthesising microbes in soil may increase their activity as temperatures rise, offsetting some of the carbon emissions expected to be released from peatland and permafrost ​Photosynthesising microbes in soil may increase their activity as temperatures rise, offsetting some of the carbon emissions expected to be released from peatland and permafrost Photosynthesising microbes in soil may increase …
