New Pavement Made From Tyres Will Save Old Faithful's Groundwater

Labour Day Weekend is one of the busiest times at Yellowstone National Park, and its famous geyser, Old Faithful, reels in 90 per cent of the park’s 3.6 million annual visitors.

Why Did 60,000 Antelope Drop Dead Over Four Days?

When 60,000 critically endangered saiga antelope dropped dead in central Kazakhstan in June, it had to have been a major bummer for the veterinarians who had just arrived to study the herd.

Humans Have Eliminated Half The World's Trees

Human beings are having an overwhelming impact on Earth’s ecosystems, whether we’re pouring plastic into the ocean or filling the skies with carbon.

Seabirds Are Eating Lots Of Plastic, And The Problem Is Getting Worse

Greenland's Ice Sheets Are Getting Cooked By Warm Ocean Currents

The retreat of Arctic sea ice has been so dramatic over the last few years that atlases are being changed. Now it turns out Greenland’s ice sheets are also melting faster than we thought — not on the visible surface, but due to currents deep below the ocean.


Earth Is Probably Locked Into At Least 90cm Of Sea Level Rise

Global sea levels are expected to rise over 90cm in the coming generations, displacing hundreds of millions of people, NASA said this week. And the space agency is prepared to catalogue the disappearance of Earth’s coastlines in rich scientific detail.


Green Tech Won't Save Our Planet

What does your vision of a sustainable future look like? Some people imagine a scenario whereby technology solves the world’s most pressing environmental problems.


Pruning The Mississippi River Could Protect New Orleans From The Next Katrina

When Hurricane Katrina devastated New Orleans a decade ago, its destructive power was unprecedented. But these days, extreme weather events are becoming eerily common. How to prevent the next big storm from walloping the Big Easy? We might need to let the mouth of the Mississippi die.


How Did A Rare, Vomit-Inducing Parasite Infect The Water Supply For 300,000 People?

More than 300,000 households in Lancashire, England have been warned to boil their water recently to kill any traces of Cryptosporidium, the BBC reports. The nasty livestock parasite, which surfaced last week, probably came from a rotting animal carcass or faeces, according to The Guardian. Lovely.


If Humans Never Existed, The World Would Have More Mammals

There aren’t many large mammals around anymore in, most of the world. That’s mostly because one mammal species — Homo sapiens — has taken a heavy toll on its competition. Now, a team of researchers demonstrates what would have happened to the world’s megafauna if humans had never existed.
