Since its inception in the 1950s, radiocarbon dating has proven indispensable to archaeologists and climate scientists, who rely on the technique to accurately date organic compounds. But a good thing just got better, owing to the discovery of two stalagmites in a Chinese cave containing a seamless chronological atmospheric record dating back to the last Ice Age.

An unbroken, high-resolution record of atmospheric carbon-12 and carbon-14 was found in a pair of stalagmites located within Hulu Cave near Nanjing, China, according to new research published today in Science. Because this record extends back to the last glacial period, to around 54,000 years ago, scientists are now equipped with a more accurate standard for use in radiocarbon calibration.

Tornadoes are some of the most destructive weather events on the planet, so understanding how they form is vital in forming early warning systems that give people plenty of time to take cover. It’s long been thought that rotation in storm clouds is the very first sign that a twister is taking shape, but new research suggests that the cloud rotation might actually be the last piece of the tornado puzzle.

While monitoring a large tornado-producing storm in central Oklahoma, meteorologist Jana Houser of Ohio University gathered readings using a mobile Doppler radar that logged wind speeds twice per minute. This painted a detailed picture of the exact moment the clouds began to rotate, but it wasn’t until afterward that Houser and her fellow researchers noticed an anomaly.

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.

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.

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 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 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).

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.
