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.
Dr Mountjoy says there is a significant underground gas source which is suspected of causing underwater landslides and may be related to deeper fluids in the subduction zone that can in turn influence earthquake behaviour.
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.
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.
Telescopes like Chandra can spot x-ray light coming from massive stars, much larger than our Sun, that are active for only a few million years, sputtering out gas and dust into space.
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.
The sun sure has flare, but Saturn and its rings have elegance and class. This spinning wheel of debris eventually coalesces into planets, and bada bing, you have a solar system.
“These offshore CO2 storage facilities are probably a reasonable idea because the benefits of storing 1 million tons per year of carbon are larger than the effects of the leakage that may occur,” says Klaus Wallmann, professor of marine biogeochemistry at the GEOMAR Center for Ocean Research in Kiel, Germany, and an author of the report.
But getting there depends on loosening regulations and borrowing drilling techniques from oil and gas companies.“It’s a great resource, but one that doesn’t get a lot of love,” said Spencer Nelson, who directs the energy innovation program at ClearPath and wrote the memo.
Dragomir said the radius gap points to possible rules both about how planets are formed, and what happens to them early on. Though some kind of atmosphere loss is a reasonable guess, it is just one of three general ideas, said Sara Seager, an astronomer at MIT who is deputy science director for the TESS mission.
“We need to have process representation to understand these mechanisms,” says Eric Kort, an atmospheric scientist at the University of Michigan, “so we can say, for example, with certain changes to temperature and the hydrological cycle, we’d expect methane emissions to increase by X amount.” Without that understanding, Kort suggests, we’re unable to answer some important questions about what looms ahead.
Machine learning software systems are learning to predict code violations, safety incidents, mechanical failures and natural disasters, directing robotic or human resources to intervene. Advances in robotics, hardware and artificial intelligence have combined to make a new vision possible for how infrastructure maintenance and repair is carried out.
The picture, taken over 5 days of observations in April 2017 using eight telescopes around the world by a collaboration known as the Event Horizon Telescope, depicts luminous gas swirling around a supermassive black hole at the center of M87, a galaxy 54 million light years away.
"Anybody can do it if you want to; you can step into the role of Bellingcat." Director Hans Pool This is director Hans Pool’s favorite scene in his new documentary Truth in a Post Truth World , which will screen this Sunday at the South by Southwest film festival.
This week, the Hubble Space Telescope found evidence of a newborn star about 1,000 light years from Earth in a nebula called NGC 1333.
Pinball in space: NASA’s Chandra X-ray Observatory found jets of particles and energy streaming from a black hole, only to run into a wall of gas and then bounce back toward the region they came from.
Consider these leftovers from a violent death some 20,000 light years away, a supernova remnant called G54.1+0.3. In this image (the nebula NGC 1333, about 1,000 light years from Earth) these specific Herbig-Haro objects, numbered 7 to 11, are speeding away from the very young star SVS 13, which had spit out highly energized jets of gas that then interacted with surrounding clouds.
Although Dawn is done, it will remain in a stable orbit around Ceres for the next 50 years or so to protect the surface from any potential contaminants left on the spacecraft from Earth.InSight landed on the dusty, rocky surface of Mars on November 26, and moments after touching down, it took this photo of the ground.
As we gather contributions from public and private stakeholders around the world, here’s where the conversation on transport and climate stands so far: Waste-to-energy technologies offer a promising alternative to more traditional renewable energy.
According to a recent study published in Nature Climate Change by Conservancy scientists and partners from Florida International University, the U.S. Environmental Protection Agency and others, healthy wetlands (think wetlands covered with plants) are net sinks for greenhouse gases in the U.S. That means, on the whole, the country’s coastal wetlands remove more greenhouse gases – especially CO2 – than they release.
