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.

In series of talks, researchers describe major effort to address climate change through carbon-free power.

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 carbon 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 deep ocean and get stored there,” said study coauthor Robert Anderson, an oceanographer at Columbia University’s Lamont-Doherty Earth Observatory.

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.

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) materials and were developed by UBC Okanagan researchers in a new study published this week in the journal Science.

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.

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:

There’s something about the meandering streak of lightning that implies random chaos. Yet bolts from the blue not only hit the same places with regularity, but successive discharges often reuse the exact same channel.

It’s never been entirely clear how the path laid down by one bolt sticks around for repeat performances, but new research has discovered lingering pockets of charge in the wake of a single lightning strike, which could provide a map for more to follow.
