Huge carbon sink exists in soil minerals

artists depiction of carbon in soilA Washington State University researcher has discovered that vast amounts of carbon can be stored by soil minerals more than a foot below the surface. The finding could help offset the rising greenhouse-gas emissions helping warm the Earth’s climate.

Marc Kramer, an assistant professor of environmental chemistry at WSU Vancouver, reports his finding in one of two related papers demonstrating how the right management practices can help trap much of the carbon dioxide that is rapidly warming the planet. » More …

Ancient Inland Northwest volcanic eruptions blocked out sun, cooling planet

Palouse Falls (c)WSU Photo ServicesThe Pacific Northwest was home to one of the Earth’s largest known volcanic eruptions, a millennia-long spewing of sulfuric gas that blocked out the sun and cooled the planet, Washington State University researchers have determined.

“This would have been devastating regionally because of the acid-rain effect from the eruptions,” said John Wolff, a professor in the WSU School of the Environment. “It did have a global effect on temperatures, but not drastic enough to start killing things, or it did not kill enough of them to affect the fossil record.”

The research, which was funded by the National Science Foundation, appears in Geology, the top journal in the field. Starting 16.5 million years ago, they say, vents in southeast Washington » More …
