'Life or death' preperations for Yellowstone supervolcano emergency

Yellowstone National Park Public Affairs confirmed that there could be a supervolcano eruption imminently - and that they were putting themselves through their paces so that they were ready for any eventuality. Spokesman Morgan Warthin said: “Every opportunity like this, every training opportunity reveals both where our strengths are. “But also how we can improve.” Mr Warthin knows that emergency services will need to be absolutely prepared if a catastrophe strikes near Mammoth in Yellowstone National Park. A model bus crash was simulated for the first time in several years, in order to steel emergency workers for a crisis. The...

Trash in the Great Pacific Garbage Patch Has More Than Quadrupled

The Great Pacific Garbage Patch is getting denser. The enormous plastic soup floating in the vast North Pacific spans more than 617,000 square miles (1.6 million square kilometers), and its density is now between four and 16 times greater than previous estimates, scientists have found. Researchers made the discovery by looking at the accumulation of plastic trash in the Pacific between California and Hawaii. They found that the patch has more than 87,000 tons (79,000 metric tons) of plastic in it. That equates to 1.8 trillion pieces of plastic, or roughly 250 pieces for every person on the planet, the...

Parts of San Francisco are sinking faster than the sea is rising

Rising seas aren’t the only problem facing low-lying coastal areas. Many of these areas are also sinking, vastly increasing the risk of flooding. In the San Francisco Bay area, sea level rise alone could inundate an area of between 50 and 410 square kilometres by 2100, depending both on how much action is taken to limit further global warming and how fast the polar ice sheets melt. But when land subsidence is also taken into account, the area vulnerable to flooding during high tides and storm surges rises to between 130 and 430 square kilometres. That’s the conclusion of Manoochehr...

We already have planet-cooling technology, the problem is, it’s killing us.

We already have planet-cooling technology, the problem is, it’s killing us.

A trope of sci-fi movies these days, from Snowpiercer to Geostorm, is that our failure to tackle climate change will eventually force us to deploy an arsenal of unproven technologies to save the planet. Think sun-deflecting space mirrors or chemically altered clouds. And because these are sci-fi movies, it’s assumed that these grand experiments in geoengineering will go horribly wrong. The fiction, new evidence suggests, may be much closer to reality than we thought. When most people hear “climate change,” they think of greenhouse gases overheating the planet. But there’s another product of industry changing the climate that has received...

Why the sun will soon get dimmer

Why the sun will soon get dimmer

Scientist say the sun is expected to go into a dimmer, cooler cycle by 2050. What does this mean for planet earth? It’s what scientists have termed a “grand minimum” — a particularly low point in what is otherwise a steady 11-year cycle. Over this cycle, the sun’s tumultuous heart races and rests. At its high point, the nuclear fusion at the sun’s core forces more magnetic loops high into its boiling atmosphere — ejecting more ultraviolet radiation and generating sunspots and flares. When it’s quiet, the sun’s surface goes calm. It ejects less ultraviolet radiation. Now scientists have scoured...
