Global warming villain CO₂ may have a surprisingly green future

The next frontier in the search for renewable energy lies less than two miles from where you are now.

Unless you’re reading this on the International Space Station.

Geothermal heat a mile or two deep in Earth’s crust is a potential source of energy that could be tapped by an unlikely carrier: carbon dioxide (CO₂), the central villain in global warming. That energy, unlike solar and wind, could be easily turned on and off without the intermediate step of being stored in a battery. And it would be constant and reliable. (more…)

Scientists Find Part of New Zealand’s Submerged “Pink Terraces”

They were called the Eighth Wonder of the World. Until the late 19^th century, New Zealand’s Pink and White Terraces along Lake Rotomahana on the North Island, attracted tourists from around the world, interested in seeing the beautiful natural formations created by a large geothermal system. But the eruption of Mt. Tarawera on June 10, 1886, buried the terraces in sediment and caused the lake basin to enlarge, engulfing the land where the terraces stood. For more than a century, people have speculated whether any part of the Pink and White Terraces survived the eruption. (more…)
