New 3D View of Methane Tracks Sources and Movement around the Globe

Posted by in categories: climatology, computing, sustainability

NASA’s new 3-dimensional portrait of methane concentrations shows the world’s second largest contributor to greenhouse warming, the diversity of sources on the ground, and the behavior of the gas as it moves through the atmosphere. Combining multiple data sets from emissions inventories, including fossil fuel, agricultural, biomass burning and biofuels, and simulations of wetland sources into a high-resolution computer model, researchers now have an additional tool for understanding this complex gas and its role in Earth’s carbon cycle, atmospheric composition, and climate system.

Since the Industrial Revolution, methane concentrations in the atmosphere have more than doubled. After carbon dioxide, methane is the second most influential greenhouse gas, responsible for 20 to 30% of Earth’s rising temperatures to date.

“There’s an urgency in understanding where the sources are coming from so that we can be better prepared to mitigate methane emissions where there are opportunities to do so,” said research scientist Ben Poulter at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Attacking Global Warming With Satellites

Global warming is a complex problem that is not easy to solve. While world leaders seem to be dragging their feet over the issue, Yotam Ariel, founder of Bluefield, believes he might have at least one piece of the puzzle sorted. Methane monitoring from space. By leveraging a network of microsatellites with a proprietary sensor, Bluefield plans to deliver alerts and analytics to oil and gas clients to help combat the inadvertent release of methane gas

Methane, a greenhouse gas, is leaking into the atmosphere. One might ask, “Why bother with methane, isn’t carbon dioxide the problem?” Well, according to the IPCC (https://www.ipcc.ch/), methane is 84 times more potent than carbon dioxide, which is clearly a bad thing for global warming. Methane is believed to be responsible for 25% of global warming and knowing who is emitting, when, and how much, would be a massive step towards reversing climate change. Since between 50 and 65% of total global methane emissions come from human activities, being able to identify and stop leaks is crucial to lowering greenhouse gases in our atmosphere.

Bluefield plans to specialize in methane gas detection and not try and solve all problems all at once and thereby reducing complexity. Further reduction in complexity is achieved by leveraging outside suppliers where applicable that complement the Bluefield plans. By reducing the complexity, Bluefield can focus on its core mission and specialty. Areas outside of detection such as the satellite parts, ground stations, the launch, and other services will be outsourced. This will allow Bluefield to quickly move through its development stages. Whereas it might take up to 10 years for a space agency like NASA, JAXA or ESA, to fund, design, test and launch a custom satellite, Bluefield aims to accomplish this as early as next year.

In fact, the prototype for the first microsatellite design has already been completed. Bluefield shortlisted several suppliers and the final selection will be made soon. The company is well on its way to testing its technology in orbit after completing both field tests and high-altitude balloon tests this year. By mounting its newly developed sensor on several backpack-sized microsatellites, Bluefield will be able to collect enough raw data to provide methane emission monitoring at a previously unthinkable level in terms of global coverage, high resolution and at a price point well below what is currently available.

More Than 3,000 Lightning Bolts Strike Greece on Thursday (video)

Posted by in category: climatology

This is not normal and there is another 3000 happening right now based on lightning tracker.


More than 3,000 lightning strikes, which occurred mostly during rainstorms, were recorded in central regions of the country on August 15, according to the National Observatory of Athens.

More US Military Power Needed in Antarctic to Deter Malign Activity, General Says

Posted by in categories: climatology, military

If the U.S. is going to do more work in cold weather climates to deter malign activity from Russia and China, one Air Force general says it will need more equipment to operate full-time in the South Pole.

Pacific Air Forces commander Gen. Charles Q. Brown said Tuesday he’d like to see a boost in “some of the capability we have, but don’t have a lot of.”

“Icebreakers, for example. LC-130s? There’s not a lot of those,” Brown said during a speech at the Mitchell Institute for Aerospace Studies in Arlington, Virginia.

5000-Year-Old Papua New Guinea Artifacts Rewrite Neolithic History

Posted by in categories: climatology, sustainability

Scientists unearth ancient Papua New Guinea artifacts in the highlands of the island that settle a longstanding archaeological argument regarding the emergence of complex culture on the island.

About 10,000 years ago, the climate changed to better suit the planting of crops and the Neolithic revolution that brought about agriculture emerged in different parts of the world at different times. In Europe and Asia it is known that at this time cultural complexity developed as people began settling and living together on farms.

Elon Musk: Tesla Model Y heat pump is some of the best engineering I’ve seen in a while

Posted by in categories: climatology, Elon Musk, engineering, sustainability

Elon Musk praised Tesla’s team for the Model Y’s heat pump — a feature that could make the electric SUV much more efficient in colder climates.

Last week, Tesla started deliveries of the Model Y, its fourth vehicle in the current lineup and fifth model ever.

Russia aims to revive science after era of stagnation

Posted by in categories: climatology, government, robotics/AI, science

In 2018, Putin approved a national research strategy that stretches to 2024. It calls for more money, extra support for early-career scientists, and some 900 new laboratories, including at least 15 world-class research centres with a focus on mathematics, genomics, materials research and robotics. Last year, the government completed a sweeping evaluation of scientific performance at its universities and institutes; it has vowed to modernize equipment in the 300 institutes that made the top quartile. And it says it wants to strengthen previously neglected areas, including climate and environmental research (see ‘Russia’s climate-science ambitions’).


Some researchers see promise in planned reforms.

How a small nuclear war would transform the entire planet

Posted by in categories: climatology, existential risks

This grim vision of a possible future comes from the latest studies about how nuclear war could alter world climate. They build on long-standing work about a ‘nuclear winter’ — severe global cooling that researchers predict would follow a major nuclear war, such as thousands of bombs flying between the United States and Russia. But much smaller nuclear conflicts, which are more likely to occur, could also have devastating effects around the world.


As geopolitical tensions rise in nuclear-armed states, scientists are modelling the global impact of nuclear war.

Confirmed: Lightning Causes Nuclear Reactions in the Sky

Posted by in categories: climatology, nuclear energy, particle physics

Circa 2017 o.o


Lightning is nuts. It’s a supercharged bolt of electricity extending from the sky to the ground that can kill people. But it can also produce nuclear reactions, according to new research.

Scientists have long known that thunderstorms can produce high-energy radiation, like this one from December, 2015 that blasted a Japanese beach town with some gamma radiation. But now, another team of researchers in Japan are reporting conclusive evidence of these gamma rays setting off atom-altering reactions like those in a nuclear reactor.
