Monster Cyclone in India Prompts the Biggest Evacuation in the Country’s History

Posted by in category: climatology

A massive cyclone is set to batter India over the next few days, spurring the biggest evacuation in the country’s history.

The extremely severe cyclone, dubbed “Fani,” is pummeling the Bay of Bengal and is projected to make landfall by Thursday night with approximately 120 mph (190 km/h) winds, with gusts up to 130 mph (210 km/h), according to the India Meteorological Department (IMD). Fani is also likely to bring “phenomenal” sea conditions in parts of the Bay of Bengal, according to the IMD.

More than 100 million people are in the path of the devastating cyclone, and nearly 900,000 people have been ordered to evacuate, the Associated Press reported. About 100,000 of those people are from the city of Puri, in the state of Odisha, which is home to the 858-year-old Jaganath Temple, the BBC reported. Officials fear that this ancient temple could be damaged by the cyclone.

Planting 1.2 Trillion Trees Could Cancel Out a Decade of CO2 Emissions, Scientists Find

Posted by in categories: climatology, space, sustainability

There is enough room in the world’s existing parks, forests, and abandoned land to plant 1.2 trillion additional trees, which would have the CO2 storage capacity to cancel out a decade of carbon dioxide emissions, according to a new analysis by ecologist Thomas Crowther and colleagues at ETH Zurich, a Swiss university.

The research, presented at this year’s American Association for the Advancement of Science conference in Washington, D.C., argues that planting additional trees is one of the most effective ways to reduce greenhouse gases.

Trees are “our most powerful weapon in the fight against climate change,” Crowther told The Independent. Combining forest inventory data from 1.2 million locations around the world and satellite images, the scientists estimate there are 3 trillion trees on Earth — seven times more than previous estimates. But they also found that there is abundant space to restore millions of acres of additional forests, not counting urban and agricultural land.

As oceans warm, microbes could pump more CO2 back into air, study warns

Posted by in categories: biological, climatology, sustainability

The world’s oceans soak up about a quarter of the carbon dioxide that humans pump into the air each year—a powerful brake on the greenhouse effect. In addition to purely physical and chemical processes, a large part of this is taken up by photosynthetic plankton as they incorporate carbon into their bodies. When plankton die, they sink, taking the carbon with them. Some part of this organic rain will end up locked into the deep ocean, insulated from the atmosphere for centuries or more. But what the ocean takes, the ocean also gives back. Before many of the remains get very far, they are consumed by aerobic bacteria. And, just like us, those bacteria respire by taking in oxygen and expelling carbon dioxide. Much of that regenerated CO2 thus ends up back in the air.

A new study suggests that CO2 regeneration may become faster in many regions of the world as the oceans warm with changing climate. This, in turn, may reduce the deep oceans’ ability to keep locked up. The study shows that in many cases, bacteria are consuming more plankton at shallower depths than previously believed, and that the conditions under which they do this will spread as water temperatures rise. The study was published this week in the journal Proceedings of the National Academy of Sciences.

“The results are telling us that warming will cause faster recycling of carbon in many areas, and that means less carbon will reach the and get stored there,” said study coauthor Robert Anderson, an oceanographer at Columbia University’s Lamont-Doherty Earth Observatory.

5 AI Breakthroughs We’ll Likely See in the Next 5 Years

Posted by in categories: climatology, robotics/AI, solar power, sustainability

Just as the modern computer transformed our relationship with bits and information, AI will redefine and revolutionize our relationship with molecules and materials. AI is currently being used to discover new materials for clean-tech innovations, such as solar panels, batteries, and devices that can now conduct artificial photosynthesis.

Today, it takes about 15 to 20 years to create a single new material, according to industry experts. But as AI design systems skyrocket in capacity, these will vastly accelerate the materials discovery process, allowing us to address pressing issues like climate change at record rates. Companies like Kebotix are already on their way to streamlining the creation of chemistries and materials at the click of a button.

Atomically precise manufacturing will enable us to produce the previously unimaginable.

Researchers develop new class of anti-ice surfaces

Posted by in categories: climatology, materials

Scraping an icy windshield can be a seasonal struggle for those that live in colder climates. But engineers from UBC’s Okanagan campus are aiming to ease that winter frustration with a new surface coating that can shed ice from large areas using little effort.

The new anti-ice coating is a new class of surfaces called low interfacial toughness (LIT) and were developed by UBC Okanagan researchers in a new study published this week in the journal Science.

Microbes may act as gatekeepers of Earth’s Deep Carbon

Posted by in categories: biological, climatology, sustainability

Two years ago a team of scientists visited Costa Rica’s subduction zone, where the ocean floor sinks beneath the continent and volcanoes tower above the surface. They wanted to find out if microbes can affect the cycle of carbon moving from Earth’s surface into the deep interior. According to their new study in Nature, the answer is affirmatively—yes they can.

This groundbreaking study shows that microbes consume and—crucially—help trap a small amount of sinking carbon in this zone. This finding has important implications for understanding Earth’s fundamental processes and for revealing how nature can potentially help mitigate climate change.

You Can Now Shop With Bitcoin on Amazon Using Lightning

Posted by in categories: bitcoin, climatology, space

Bitcoin spenders can now use the lightning network to shop at e-commerce sites like Amazon.

Crypto payment processing startup Moon announced today that any lightning-enabled wallet can now also be used through Moon’s browser extension. Before this lightning feature, roughly 250 beta users already used Moon to spend crypto on e-commerce sites by connecting the browser extension to exchange accounts like Coinbase.

Moon CEO Ken Kruger told CoinDesk:
