Volcanic Gases Could Deplete Ozone Layer

  A new study has found that massive volcanic eruptions that took place over the past 70,000 years in Nicaragua could have injected enough gases into the atmosphere to temporarily thin the ozone layer. The study also concluded that if such an event took pace today, the amount of gases released could equal twice the […]

Top 20 Planetsave Stories in May

Hello Planetsavers! I thought I’d start doing a monthly wrap-up of our top 20 posts for people to have a glance at. Many of the top stories this month, as you’ll notice, were clearly tied into major world news events. Google is the main traffic driver for the large majority of sites on the Internet and ours isn’t an exception. Covering environmental news consistently, this often results in the biggest news stories rising to the top.

Did the Impending 'Super Moon' Cause Japan's Earthquake?

astrologer has also predicted that such a close perigee would/must somehow perturb the earth’s (tectonic) integrity so much that it will trigger major earthquakes and even volcanoes (not simply severe storms). Although he is not clear on the exact lunar-geo-mechanisms that would produce these quakes, never-the-less this lunar-induced disaster scenario quickly set the Web abuzz with yet another wave of doom-and-gloom “apocalypticism.”

Timing is everything.

Hawaii Volcano Erupts [VIDEOS]

Hawaii’s Kīlauea volcano, one of the most active and dangerous volcanoes in the world (and also the most visited volcano in the world), began erupting violently yesterday after a nearby crater collapsed on Saturday. Enjoy the videos above and below capturing this, via the AP and Reuters/Guardian, respectively. “Hawaii Volcano Observatory scientists said the floor of […]

Limited Nuclear War Could Halt Global Warming, Short Term, NASA Predicts

The scientists used a general circulation model known as ModelE (developed at NASA’s Goddard Institute for Space Studies, New York). The model calculates ocean-atmosphere coupling effects in addition to allowing varying aerosol inputs.

The initial input for the simulation was 5 teragrams (megatons) of black carbon particles injected into Earth’s upper troposphere. This is the estimated result of the surface detonation of 100 Hiroshima-size bombs (each equivalent to 15K tons of TNT).

"Humans Don't Create as Much CO2 as Volcanoes" is Totally Wrong [VIDEOS]

A common claim of climate change disinformers is that humans don’t release a significant amount of CO2. Bringing that absurdity to another level, you may even see claims out there that volcanoes release more CO2 than humans. Way wrong. “Human activities release more than 130 times the amount of CO2 emitted by volcanoes — the […]

Hawaii Sitting Shallow Atop Magma

An Ohio State University honours undergraduate student has found that the Hawaiian Island volcani chain sits atop a single magma chamber which is much closer to the surface than was originally supposed. “Hawaii was already unique among volcanic systems, because it has such an extensive plumbing system, and the magma that erupts has a unique […]

No Eruption Imminent from Iceland Volcano

Geophysicists who have been monitoring the Grimsvotn volcano in Iceland have announced that floodwaters are receding and tremors are decreasing. This after fears just a few days ago that the country’s most active volcano could erupt soon. The lake and surrounding glacier had begun melting, with water levels having tripled according to Gunnar Sigurdsson of […]

Volcanoes: The 'X Factor' in Climate Change

Apart from the major disruption in flight traffic and the economy, the Icelandic volcano eruption promises in the short-term to disrupt upper atmospheric circulation patterns and temperatures, with an additional impact due to sulfuric acid “nucleation” and subsequent acid rain. But the medium to long-term impacts of continuous, or increasing, volcanic eruptions is a matter of on-going scientific debate.
