In the case of, say, a gasoline-powered car, the fuel is mixed with air, crammed into a piston chamber, and set alight, causing it to jump more than 1,000 degrees in temperature.
Improvements to air traffic control could also help reduce emissions by as much as 12 percent, per a 1999 estimate from the Intergovernmental Panel on Climate Change.

“When the Chinese economy does recover, they are likely to see an increase in emissions in the short term to sort of make up for lost time, in terms of production,” says Zeke Hausfather, a climate scientist and the director of climate and energy at the Breakthrough Institute, which advocates for climate action.

Louie learned from his guide that workers spend 12-hour shifts dodging plumes of poisonous smoke (with many protected only by rags tied around their mouths) while carrying up to 180 pounds of sulfur on their backs.
The World Economic Forum predicts plastic production will double in the next 20 years.“In the context of a world trying to shift off of fossil fuels as an energy source, this is where [oil and gas companies] see the growth,” said Steven Feit, a staff attorney at the Center for International Environmental Law, an advocacy group.

But they’ve been working to gain access to American electric utilities, long before tensions between the two countries came to a head .On Thursday morning, industrial control system security firm Dragos detailed newly revealed hacking activity that it has tracked and attributed to a group of state-sponsored hackers it calls Magnallium.
Protesters donned foil-lined gas masks to hide their identities and dim the glare of police flashlights.Demonstrators have donned body armor and lined their goggles with reflective film to foil police flashlights and mask their identities.
Mina is one of countless Iranians in the US who have tried to contact friends and family members in Iran amid a nationwide internet shutdown that has lasted six days so far.
Air cofounder Stafford Sheehan introduces hydrogen gas and carbon dioxide gas into the company's reactor.
Even though Duren’s California Methane Survey looked only at focused point-source emissions, because it looked at so many and for so long, Duren’s team was able to conclude that by themselves those sources coughed out 500,000 metric tons of methane a year, give or take, and that just 10 percent of the emitters were responsible for 60 percent of the total.
It would seem, then, that the aye-aye (so named because of its cries) wanders the forests of Madagascar giving the world the highly elongated finger .But now, a discovery that really ruins that gag: While exploring the anatomy of the aye-aye’s forearm and hand, a group of researchers discovered the critter has tiny pseudothumbs that likely help it grip branches.
Last week, Santa Fe-based Descartes Labs (where Mark is a cofounder) announced a bold initiative to utilize satellite mapping and modeling to monitor methane emissions, starting in the world’s highest-producing oilfield, the Permian Basin.
Here are some highlights: Ben van Beurden, CEO, Royal Dutch Shell: “Ultimately, (the) Paris (agreement on climate) is going to be met..In the end it is the responsibility of industry, companies like us, to make sure that the transition is going to be as orderly as possible and not going to be disruptive.”.
Amazon Employees for Climate Justice have outlined three appeals for their employer: Stop donating to politicians and lobbying groups that deny the reality of climate change, stop working with oil and gas companies to optimize fossil fuel extraction, and achieve zero carbon emissions by 2030.
In 1990, the state tightened its standards again, and added a new component: Its Low-Emission Vehicle program required that automakers sell some zero-emission vehicles, as in battery and fuel-cell electric cars.
In 2018, researchers at the Environmental Defense Fund along with scientists at 12 universities and two federal agencies published a paper in the journal Science concluding that the amount of methane leaking from oil and gas operations was 30 million metric tons per year, or about 60 percent more than EPA estimates.
The deal includes BP’s operating stake in Prudhoe Bay, the largest-producing oilfield in U.S. history, as well as all its Alaskan pipelines, London-based BP said Tuesday in a statement.
“Once the industry scales up, renewable hydrogen could be produced from wind or solar power for the same price as natural gas in most of Europe and Asia,” Kobad Bhavnagri, BNEF’s head of special projects, said in the report on Wednesday.
Frustration with buying fruit and vegetables that are never ready to eat prompted a 13-year-old Tauranga girl to a design a machine to help.Bay of Plenty Science Fair 2019 winner Anamaya Taylor.
Space Photos of the Week: A Trip for Thee to Galaxies Three. NGC 3169 is a spiral galaxy, and the angle at which Hubble catches it gives us a good perspective on what’s happening there.
But in a world where corporations plant trees to offset their carbon emissions, we badly need to know if their numbers add up, or if they are undermined by the complex chemistry of trees and methane.“In the seasonally flooded part of the Amazon, the trees become a massive chimney for pumping out methane,” says one researcher.
How well a cooler can do this will depend on three key factors: insulation, air, and ice. Open-cell is the type of foam that is used in soft-sided lunch totes and the like, while hard-sided coolers generally contain closed-cell foam in their walls.
Now, three centuries on, the concept has made it into the Bentley Bentayga Hybrid, the world’s first ultra-luxury, battery-powered SUV. Bentley’s interior design team used a version of an old landscape feature called a ha-ha to make the dashboard appear seamless to the driver.
