Even the most enthusiastic believers in direct air capture stop short of describing it as a miracle technology. It’s more frequently described as an old idea — “scrubbers” that remove CO₂ have been used in submarines since at least the 1950s — that is being radically upgraded for a variety of new applications. It’s arguably the case, in fact, that when it comes to reducing our carbon emissions, direct air capture will be seen as an option that’s too expensive and too modest in impact. “The only way that direct air capture becomes meaningful is if we do all the other things we need to do promptly,” Hal Harvey, a California energy analyst who studies climate-friendly technologies and policies, told me recently. Harvey and others make the case that the biggest, fastest and cheapest gains in addressing atmospheric carbon will come from switching our power grid to renewable energy or low-carbon electricity; from transitioning to electric vehicles and imposing stricter mileage regulations on gas-powered cars and trucks; and from requiring more energy-efficient buildings and appliances. In short, the best way to start making progress toward a decarbonized world is not to rev up millions of air capture machines right now. It’s to stop putting CO₂ in the atmosphere in the first place.
Gamebreaker: Billy Vunipola – Such a shame that we could not see where he stands in the pantheon of great global No 8s against Kieran Read in the summer. What a talent the Englishman is. Completely dominant last season until injury felled him – he will be vital once more from the back of the scrum. He is still only 24 too!
Gary thinks the flow of water is now increasing and is turning vivid orange, and Jack volunteers to scoop some of it into two water bottles right before a sudden downpour threatens to wash out the experiment. He takes the samples to researcher Paul Troutman, who is waiting in the Oak Island research center.
A Ural Airlines passenger plane carrying 225 people bound for Moscow made an emergency landing in Baku after the cabin crew thought there might be a bomb on board the plane, RIA news agency cited Baku’s airport as saying.

Pricing will be even harder. Few utilities in the world charge consumers the full cost of the water they use. And even in countries where they do, a water subsidy may be included in the cost of the goods people buy in shops. To persuade people to recognise and pay for the water-intensity of their lifestyles may require concerted campaigns of the type that have helped cut smoking rates in many places. But because they will affect the entire population, it will be even harder. On the other hand, as experience in some unlikely places has shown—Phnom Penh, the capital of Cambodia, for example—poor people will pay for a clean, reliable source of water. After all, in much of the world, they already pay over the odds for dirty, dangerous and erratic supplies.
Club conundrum: Winning. It sounds blindingly obvious, probably because it is. Irish need to win five games – that has kept four teams up in the last five years, Newcastle stayed in the league with three wins in 2014. It will not be easy – Irish do not have a fortress home ground, but they do have the talent and coaching nous to stay up. Beating Worcester twice should be their first aim.
There happens to be a name for things that can do this kind of extraction work: negative-emissions technologies, or NETs. Some NETs, like trees and plants, predate us and probably don’t deserve the label. Through photosynthesis, our forests take extraordinary amounts of carbon dioxide from the atmosphere, and if we were to magnify efforts to reforest clear-cut areas — or plant new groves, a process known as afforestation — we could absorb billions more metric tons of carbon in future years. What’s more, we could grow crops specifically to absorb CO₂ and then burn them for power generation, with the intention of capturing the power-plant emissions and pumping them underground, a process known as bioenergy with carbon capture and storage, or BECCS. Other negative-emissions technologies include manipulating farmland soil or coastal wetlands so they will trap more atmospheric carbon and grinding up mineral formations so they will absorb CO₂ more readily, a process known as “enhanced weathering.”
