Discovery of phosphine in Venus’ atmosphere could be sign of life

James Clerk Maxwell Telescope…1 of 2 used to detect phosphine on Venus

With phosphine in mind, an international team of researchers used two ground-based telescopes — the James Clerk Maxwell Telescope in Hawaii and the Atacama Large Millimeter Array in Chile — to search for any possible signatures of phosphine in Venus’ atmosphere. Sure enough, they found the gas at a concentration of five to 20 parts per billion in the atmosphere. That’s a lot when you compare it to how much is found on Earth, where the gas is concentrated in parts per trillion and parts per quadrillion. “That is all very much evidence pushing towards this exotic explanation of something replenishing it and something making it at large quantities,” says Clara Sousa-Silva…

If the phosphine detection is confirmed, then people will set to work figuring out where it’s coming from. It may turn out that life isn’t even the best explanation. The phosphine may have been found in clouds with moderate temperatures, but the area is still a ghastly place for life to survive, even for the hardiest of microorganisms. “There’s nothing definitive saying it is biology,” Rakesh Mogul, a biological chemist at California State Polytechnic University focusing on extreme microbial life, who is not involved in the study, tells The Verge. “There’s still a lot of unknowns. And it’s nice to put biology as the answer, but really, as scientists, we need to back it up and make sure we exhaustively study all the other possibilities.”

Nice to see scientists in charge of this information gathering and analysis. Imagine the hullabaloo if our politicians had authority over this research.

Koch Brothers make a market in the dirtiest fuel on Earth

Assumption Park gives residents of this city lovely views of the Ambassador Bridge and the Detroit skyline. Lately they’ve been treated to another sight: a three-story pile of petroleum coke covering an entire city block on the other side of the Detroit River.

Detroit’s ever-growing black mountain is the unloved, unwanted and long overlooked byproduct of Canada’s oil sands boom…And no one knows quite what to do about it, except Koch Carbon, which owns it.

The company is controlled by Charles and David Koch, wealthy industrialists who back a number of conservative and libertarian causes including activist groups that challenge the science behind climate change. The company sells the high-sulfur, high-carbon waste, usually overseas, where it is burned as fuel.

The coke comes from a refinery alongside the river owned by Marathon Petroleum, which has been there since 1930. But it began refining exports from the Canadian oil sands — and producing the waste that is sold to Koch — only in November…

An initial refining process known as coking, which releases the oil from the tarlike bitumen in the oil sands, also leaves the petroleum coke, of which Canada has 79.8 million tons stockpiled. Some is dumped in open-pit oil sands mines and tailing ponds in Alberta. Much is just piled up there.

Detroit’s pile will not be the only one. Canada’s efforts to sell more products derived from oil sands to the United States, which include transporting it through the proposed Keystone XL pipeline, have pulled more coking south to American refineries, creating more waste product here…

Residents on both sides of the Detroit River are concerned that the coke mountain is both an environmental threat and an eyesore…

Coke, which is mainly carbon, is an essential ingredient in steelmaking as well as producing the electrical anodes used to make aluminum…While there is high demand from both those industries, the small grains and high sulfur content of this petroleum coke make it largely unusable for those purposes, said Kerry Satterthwaite, a petroleum coke analyst at Roskill Information Services, a commodities analysis company based in London.

It is worse than a byproduct,” Ms. Satterthwaite said.“It’s a waste byproduct that is costly and inconvenient to store, but effectively costs nothing to produce…”

The Environmental Protection Agency will no longer allow any new licenses permitting the burning of petroleum coke in the United States. But D. Mark Routt, a staff energy consultant at KBC Advanced Technologies in Houston, said that overseas companies saw it as a cheap alternative to low-grade coal. In China, it is used to generate electricity, adding to that country’s air-quality problems. There is also strong demand from India and Latin America for American petroleum coke, where it mainly fuels cement-making kilns.

“I’m not making a value statement, but it comes down to emission controls,” Mr. Routt said. “Other people don’t seem to have a problem, which is why it is going to Mexico, which is why it is going to China.”

“One man’s junk is another man’s treasure,” he said. One of the world’s largest dealers of petroleum coke is the Oxbow Corporation, which sells about 11 million tons of fuel-grade coke a year. It is owned by William I. Koch, a brother of David and Charles.

The people who deal in this deadly waste, who care less than any other clique in American capitalism about the lives, lifestyle and lifespan of ordinary American citizens – stockpile this crap alongside a metropolitan river. After turning an extra profit from a dirty byproduct of the dirtiest fuel source on Earth – they couldn’t care less about the air and water they befoul where they store this petro-coke before shipping it off to be burned. Then, in turn, the Koch Bros. profit from fouling the air of the whole planet.
