Humans may be reversing the climate clock

Posted by in categories: climatology, futurism

Our future on Earth may also be our past. In a study published Monday (Dec. 10, 2018) in the Proceedings of the National Academy of Sciences, researchers show that humans are reversing a long-term cooling trend tracing back at least 50 million years. And it’s taken just two centuries.

Massive Cave Discovered in Canada, Named After ‘Star Wars’ Beast

Posted by in categories: climatology, sustainability

A massive, previously unexplored cave discovered by accident in Canada has been named “Sarlacc’s Pit,” after the multi-tentacled alien beast that first made an appearance in Star Wars: Return of the Jedi.

Officials from Canada’s Ministry of Environment and Climate Change first came across the huge cavern in Wells Gray Provincial Park in British Columbia while conducting a caribou count by helicopter in March.

Harvard Scientists to Release Sun-Dimming Sky Chemical in 2019

Posted by in categories: climatology, engineering, military, sustainability

Critics say that geoengineering efforts are Band-Aid solutions that treat the symptoms of climate change instead of the cause: global carbon emissions. Jim Thomas, the co-executive director of an environmental advocacy organization called the ETC Group, told Nature that he fears the Harvard project could push the concept of geoengineering into the mainstream.

But advocates say that anything that could buy some extra time in the face of looming climate catastrophe is worth exploring.

“I’m studying a chemical substance,” Harvard researcher Zhen Dai told Nature. “It’s not like it’s a nuclear bomb.”

Elon Musk says there’s a 70% chance he’s going to move to Mars

Posted by in categories: climatology, Elon Musk, engineering, habitats, space travel

Elon Musk wants humans to make it to Mars. With his company SpaceX at his back, he’s pushed forward with some incredibly bold claims about what is possible for mankind on the Red Planet. He’s shown off concepts for Mars settlements and even called out scientists who say climate engineering on the planet is impossible.

Now, in an interview with HBO’s Axios, Musk doubles down on one of the more off-the-wall claims he’s made during his years in the spotlight. Mars, he says, will be his eventual home, and he estimates his odds of moving to the planet at a generous 70%.

The Largest Meteorite Ever Found in the United States

Posted by in category: climatology

The Willamette Meteorite weighs 15.5 tons. This iron meteorite, which was found in Oregon. It is the largest meteorite found in North America.

The Willamette Meteorite is an iron-nickel meteorite discovered in the U.S. state of Oregon. It is the largest meteorite found in North America and the sixth largest in the world.

There was no impact crater at the discovery site; researchers believe the meteorite landed in what is now Canada or Montana, and was transported as a glacial erratic to the Willamette Valley during the Missoula Floods at the end of the last Ice Age (~13,000 years ago).

How the environment is connected to economic growth — and how to boost both

Posted by in categories: business, climatology, economics, sustainability

Earth’s natural resources largely determine the global economy’s ebb and flow. As such, the effects of climate change continue to cause concern among economists and environmentalists alike.

In 2018, professors William Nordhaus and Paul Romer won the Nobel Prize in Economics for their work exploring how climate change affects economic stability. Ultimately, the pair’s research found the phenomena to be closely linked. The case for investment in sustainable ventures is clear: Without such commitments, both the planet and the global economic ecosystem will suffer.

Sustainable investments may jump start the slow process of changing consumer habits. Below, we examine the economy-boosting benefits of environmentally friendly business models — and how sustainable investment plays an important role.

We’re going to Jezero!

Posted by in categories: chemistry, climatology, space

At Jezero, Mars 2020’s goal will be “to explore the history of water and chemistry in an ancient crater lake basin and associated river-delta environments to probe early Martian climates and search for life.”

NASA announced this morning the selection of Jezero crater for the landing site of the Mars 2020 mission. Jezero is a 45-kilometer-wide crater that once held a lake, and now holds a spectacular ancient river delta.

A dark matter hurricane is headed our way

Posted by in categories: climatology, cosmology

According to a recent paper, the Earth is caught directly in the crosshairs of a cosmic hurricane. A swarm of nearly 100 stars, accompanied by an even greater amount of dark matter, is aimed directly at our stellar neighborhood and there’s nothing we can do to stop it; in fact, the vanguard is already upon us. This sounds like a perfect summer blockbuster movie, starring The Rock and Chris Pratt, or maybe Scarlett Johansson and Charlize Theron.

The Tragedy of the Commons, Revisited

Posted by in categories: climatology, governance

Over two decades, I’ve worked with many collaborators studying infrastructure commons and knowledge commons. We developed the Governing Knowledge Commons framework, adapting Ostrom’s empirical approach to the special characteristics of knowledge resources. Understanding how communities share and develop knowledge is crucial in today’s “information society.” And, of course, sharing and developing knowledge is critical to successful governance of natural resources, especially on a global scale. Using the GKC framework, we’ve made substantial progress toward an empirical picture of knowledge-related commons governance. But it’s not nearly enough. Here’s why.

A classic study of the perils of resource sharing, with implications for how we deal with climate, has been updated.
