In the fog chamber, a thick cool mist rolls from one end to the other blurring glasses, wetting caps and coats and sending water dripping down the latest test panel.

University of Washington students have been testing low-cost materials capable of harvesting water from fog in a temporary “hoop house” next to the Botany Greenhouse. They create the fog with a specially adapted power washer and record how much water condenses and drips off various panels of low-cost materials, such as shade cloth. (more…)

Climate Change Boosts Then Quickly Stunts Plants, Decade-long Study Shows

*Global warming may initially make the grass greener, but not for long*

Global warming may initially make the grass greener, but not for long, according to new research results.

The findings, published this week in the journal Nature Climate Change, show that plants may thrive in the early stages of a warming environment but then begin to deteriorate quickly.

“We were really surprised by the pattern, where the initial boost in growth just went away,” said scientist Zhuoting Wu of Northern Arizona University (NAU), a lead author of the study. “As ecosystems adjusted, the responses changed.” (more…)

*In “The Great Dying” 250 million years ago, the end came slowly*

The deadliest mass extinction of all took a long time to kill 90 percent of Earth’s marine life–and it killed in stages–according to a newly published report.

It shows that mass extinctions need not be sudden events.

Thomas Algeo, a geologist at the University of Cincinnati, and 13 colleagues have produced a high-resolution look at the geology of a Permian-Triassic boundary section on Ellesmere Island in the Canadian Arctic. (more…)

Palo Alto, CA — By 2100 only 18% to 45% of the plants and animals making up ecosystems in global, humid tropical forests may remain as we know them today, according to a new study led by Greg Asner at the Carnegie Institution’s Department of Global Ecology.
