What needs to happen by COP24 to keep the Paris Agreement on track?

COP23 video: What needs to happen by COP24 to keep the Paris Agreement on track? | Carbon Brief

Carbon Brief has been talking to a range of people attending COP23, the latest annual round of international climate negotiations being held this year in Bonn, Germany.

A large proportion of the talks has been focused on making progress across a range of issues before the next COP, which is due to be held in Katowice, Poland.

These include finalising the format of the “Talanoa dialogue”, the new Fijian name for the collective stocktake (or “facilitative dialogue”) scheduled for 2018 to allow countries to assess their progress towards meeting the long-term goals of the Paris Agreement on climate change.

Carbon Brief asked delegates what they thought needs to happen by COP24 to maintain the momentum of the Paris Agreement. More

The world’s first “negative emissions” plant has opened in Iceland—turning carbon dioxide into stone


There’s a colorless, odorless, and largely benign gas that humanity just can’t get enough of. We produce 40 trillion kg of carbon dioxide each year, and we’re on track to cross a crucial emissions threshold that will cause global temperature rise to pass the dangerous 2°C limit set by the Paris climate agreement.
But, in hushed tones, climate scientists are already talking about a technology that could pull us back from the brink. It’s called direct-air capture, and it consists of machines that work like a tree does, sucking carbon dioxide (CO2) out from the air, but on steroids—capturing thousands of times more carbon in the same amount of time, and, hopefully, ensuring we don’t suffer climate catastrophe.
There are at least two reasons that, to date, conversations about direct air capture have been muted. First, climate scientists have hoped global carbon emissions would come under control, and we wouldn’t need direct air capture. But most experts believe that ship has sailed. That brings up the second issue: to date, all estimates suggest direct air capture would be exorbitantly expensive to deploy.
For the past decade, a group of entrepreneurs—partly funded by billionaires like Bill Gates of Microsoft, Edgar Bronfman Jr. of Warner Music, and the late Gary Comer of Land’s End—have been working to prove those estimates wrong. Three companies—Switzerland’s Climeworks, Canada’s Carbon Engineering, and the US’s Global Thermostat—are building machines that, at reasonable costs, can capture CO2 directly from the air. (A fourth company, Kilimanjaro Energy, closed shop due to a lack of funding.)
Over the past year, I’ve been tracking the broader field of carbon capture and storage, which aims to capture emissions from sources such as power plants and chemical factories. Experts in the field look at these direct-air-capture entrepreneurs as the rebellious kids in the class. Instead of going after the low-hanging fruit, one expert told me, these companies are taking moonshots—and setting themselves up for failure.
