NASA Confirms Thousands of Massive, Violent Volcanic “Super Eruptions” on Mars
Scientists found evidence that a region of northern Mars called Arabia Terra experienced thousands of “super eruptions,” the biggest volcanic eruptions known, over a 500-million-year…
What Lies Beneath: Volcanic Secrets Revealed – “We’ve Been Misled, Geologically Deceived”
Lava samples have revealed a new truth about the geological make-up of the Earth’s crust and could have implications for volcanic eruption early warning systems,…
International Observatories Assemble To Solve “Energy Crisis” on Jupiter
Sitting more than five times the distance from the Sun as Earth, Jupiter is not expected to be particularly warm. Based on the amount of…
Ancient Sea Ice Core – Extracted From Adélie Land in Antarctica – Sheds Light on Modern Climate Change

Extensive Chains of Volcanoes Provides Safety Valve for Earth’s Long-Term Climate
Extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon dioxide (CO2), stabilizing temperatures at Earth’s surface. An international research…
Water Blisters Trapped Beneath Greenland’s Thick Ice Sheet Could Provide Critical Hydrological Insight
Water “blisters” trapped beneath the thick interior of Greenland’s ice sheet could provide critical insight into the hydrological network coursing deep below Earth’s second largest…
Martian Dust Storms Play a Huge Role in Drying Out the Red Planet
Mars scientists have long suspected that the Red Planet, which was once warm and wet like Earth, has lost most of its water to outer…
Jupiter’s Gigantic Super Polar Cyclones Are Here To Stay
Weizmann Institute scientists reveal how gigantic cyclones remain stable at both of Jupiter’s poles. Until recently, before NASA’s Juno space probe entered its orbit around…
Global Distribution of Toxic Pollution and Climate Change Revealed in New Analysis
And provides top-ten list of countries at highest risk — and likely most equipped to immediately begin pollution risk reduction. A new analysis of global…
More Research Needed To Determine “Tipping Point” of Supervolcanoes
Scientists say it is extremely challenging to try and predict when a supervolcano might erupt again due to the sheer diversity of events that have…
The Arctic Ocean’s Deep Past Provides Clues to Its Imminent Future Under a Global Warming Regime
Nitrogen isotopes reveal that stratification of Arctic waters will prevent surface plankton from receiving enough nutrients to grow abundantly. As the North Pole, the Arctic…
Volcanoes Act as a Safety Valve for Earth’s Long-Term Climate – Stabilizing Surface Temperatures
Scientists at the University of Southampton have discovered that extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon dioxide…
