Saudi Arabia wanted to choke US shale oil producers out of business but its plan has backfired. Now facing low oil prices, Saudi Arabia is losing friends in Washington even faster than its credit rating.
Researchers working in Iceland say they have discovered a new way to trap the greenhouse gas carbon dioxide (CO2) deep underground: by changing it into rock. Results published this week in Science show that injecting CO2 into volcanic rocks known as basalt triggers a reaction that rapidly forms new carbonate minerals—potentially locking up the gas forever. Most other tests of carbon capture and storage (CCS) have taken place in sandstone formations. But sandstone is too chemically inert to foster CO2-trapping reactions, and scientists worry that gas injected into it could leak back into the atmosphere. Scientists say the new results could help solve some of the technical problems that have kept CCS projects from being commercially successful. But they say the main obstacle—high cost—is one that only changes in policy can overcome.
POLICE in the Brebes regency in the northwest of Central Java have confirmed that as many as 18 people died during a "horror" traffic jam that lasted over 20 hours on Tuesday.
Road users travelling from Jakarta to Tegal on the East Brebes toll road had to endure hours in traffic. Reports varied on the amount of time people waited as traffic came to a standstill, with some saying the jam lasted for 35 hours.
Brebes chief medical officer Sri Gunadi Parwoko said that 12 of the victims died from fatigue, while five died during an accident at a road crossing, and another of undisclosed reasons.
According to Lensa Indonesia, some of those who died from fatigue had congenital diseases made worse from the stress and heat of being stuck in the traffic.
Sri also said that it was difficult to reach those who were suffering, as ambulances and motorbikes were impeded by the slow-moving vehicles and could not locate the victims in time.
Many, if not all, of those travelling yesterday were attempting to reach their hometowns in time to celebrate Eid, which marks the end of Ramadan.
Severe traffic jams have made travelling through the East Brebes toll road a nightmare on frequent occasions. President Joko "Jokowi" Widodo said on Monday that the government will "hopefully" be able to address the issue within the next two years, reports Tempo.
In 1998, Micheal Bay directed a science fiction disaster thriller film called Armageddon in which a group of deep-core drillers was sent by NASA to stop a gigantic asteroid on a collision course with Earth. Well, in ten years from now, drilling in space is going to be a reality.
Because of global warming our future looks sober. This is what is will look like.
Khannea Suntzu's insight:
BETWEEN FIVE AND SIX DEGREES OF WARMING
Although warming on this scale lies within the IPCC’s officially endorsed range of 21st-century possibilities, climate models have little to say about what Lynas, echoing Dante, describes as “the Sixth Circle of Hell”.
To see the most recent climatic lookalike, we have to turn the geological clock back between 144m and 65m years, to the Cretaceous, which ended with the extinction of the dinosaurs. There was an even closer fit at the end of the Permian, 251m years ago, when global temperatures rose by – yes – six degrees, and 95% of species were wiped out.
That episode was the worst ever endured by life on Earth, the closest the planet has come to ending up a dead and desolate rock in space.” On land, the only winners were fungi that flourished on dying trees and shrubs. At sea there were only losers. Warm water is a killer. Less oxygen can dissolve, so conditions become stagnant and anoxic.
Oxygen-breathing water-dwellers – all the higher forms of life from plankton to sharks – face suffocation. Warm water also expands, and sea levels rose by 20 metres.” The resulting “super-hurricanes” hitting the coasts would have triggered flash floods that no living thing could have survived. There are aspects of the so-called “end-Permian extinction” that are unlikely to recur – most importantly, the vast volcanic eruption in Siberia that spread magma hundreds of metres thick over an area bigger than western Europe and shot billions of tonnes of CO2 into the atmosphere. That is small comfort, however, for beneath the oceans, another monster stirred – the same that would bring a devastating end to the Palaeocene nearly 200m years later, and that still lies in wait today.
Methane hydrate. What happens when warming water releases pent-up gas from the sea bed: First, a small disturbance drives a gas-saturated parcel of water upwards. As it rises, bubbles begin to appear, as dissolved gas fizzles out with reducing pressure – just as a bottle of lemonade overflows if the top is taken off too quickly. These bubbles make the parcel of water still more buoyant, accelerating its rise through the water. As it surges upwards, reaching explosive force, it drags surrounding water up with it. At the surface, water is shot hundreds of metres into the air as the released gas blasts into the atmosphere. Shockwaves propagate outwards in all directions, triggering more eruptions nearby. The eruption is more than just another positive feedback in the quickening process of global warming.
Unlike CO2, methane is flammable. Even in air-methane concentrations as low as 5%, the mixture could ignite from lightning or some other spark and send fireballs tearing across the sky. The effect would be much like that of the fuel-air explosives used by the US and Russian armies – so-called “vacuum bombs” that ignite fuel droplets above a target. According to the CIA, those near the ignition point are obliterated. Those at the fringes are likely to suffer many internal injuries, including burst eardrums, severe concussion, ruptured lungs and internal organs, and possibly blindness.” Such tactical weapons, however, are squibs when set against methane-air clouds from oceanic eruptions.
Scientists calculate that they could “destroy terrestrial life almost entirely (251m years ago, only one large land animal, the pig-like lystrosaurus, survived). It has been estimated that a large eruption in future could release energy equivalent to 108 megatonnes of TNT – 100,000 times more than the world’s entire stockpile of nuclear weapons. Not even Lynas, for all his scientific propriety, can avoid the Hollywood ending. “It is not too difficult to imagine the ultimate nightmare, with oceanic methane eruptions near large population centres wiping out billions of people – perhaps in days. Imagine a ‘fuel-air explosive’ fireball racing towards a city – London, say, or Tokyo – the blast wave spreading out from the explosive centre with the speed and force of an atomic bomb. Buildings are flattened, people are incinerated where they stand, or left blind and deaf by the force of the explosion. Mix Hiroshima with post-Katrina New Orleans to get some idea of what such a catastrophe might look like: burnt survivors battling over food, wandering far and wide from empty cities.
Then would come hydrogen sulphide from the stagnant oceans. “It would be a silent killer: imagine the scene at Bhopal following the Union Carbide gas release in 1984, replayed first at coastal settlements, then continental interiors across the world. At the same time, as the ozone layer came under assault, we would feel the sun’s rays burning into our skin, and the first cell mutations would be triggering outbreaks of cancer among anyone who survived. Dante’s hell was a place of judgment, where humanity was for ever punished for its sins. With all the remaining forests burning, and the corpses of people, livestock and wildlife piling up in every continent, the six-degree world would be a harsh penalty indeed for the mundane crime of burning fossil energy.
Despite a record increase in renewable energy use in 2015, and a drop in coal consumption, a rise in oil demand drove overall fossil fuel consumption up by 0.6%, and global carbon dioxide emissions once again set a new all-time record high.
In just a matter of decades, asteroids may be flying into mining outposts throughout space. At least that’s what a California company known as Made in Space would like to see. They were recently funded by NASA in order to investigate how to begin turning asteroids into massive, autonomous spacecrafts. The project is called RAMA, …
Climate change may have inspired the clean-energy revolution, but price has made it inevitable, Secretary of Energy Ernest Moniz said Thursday, citing plunging prices in solar, wind and efficient innovations like LED lighting.
