*Ordinary drinking glasses and atmospheric dust particles break apart in similar patterns*
Clues to future climate may be found in the way an ordinary drinking glass shatters.
Results of a study published this week in the journal Proceedings of the National Academy of Sciences find that microscopic particles of dust can break apart in patterns that are similar to the fragment patterns of broken glass and other brittle objects. (more…)
Scientists have long known that large volcanic explosions can affect the weather by spewing particles that block solar energy and cool the air.
Some suspect that extended “volcanic winters” from gigantic eruptions helped kill off dinosaurs and Neanderthals.
In the summer following Indonesia’s 1815 Tambora eruption, frost wrecked crops as far away as New England, and the 1991 blowout of the Philippines’ Mount Pinatubo lowered average global temperatures by 0.7 degrees F — enough to mask the effects of greenhouse gases for a year or so. (more…)
WASHINGTON—Rocket exhaust could become a significant contributor to global climate change in coming decades, according to a new study. The research finds that soot emitted by rockets — not their carbon dioxide emissions — has the greater potential to contribute to global climate change in coming decades. (more…)
ANN ARBOR, Mich. — To watch a magician transform a vase of flowers into a rabbit, it’s best to have a front-row seat. Likewise, for chemical transformations in solution, the best view belongs to the molecular spectators closest to the action.
The idea is simple. Sunrays will hit the painted glass, the dyes will capture (absorb) the rays and will bounce it out to the edges of the glass where the tiny solar cells await the supply. And the house or factory owners are happy as they will not bear any bad name as carbon dioxide emitters.
‘Desertec’ – a project backed by the Jordanian Prince Hassan bin Talal, is aimed to use the deserts along the coast of northern Africa and some Middle East countries, to capture the Sun’s rays and to use this solar power for two distinct increasing demands – power generation and freshwater. Guardian reports about the scheme on its Sunday online edition.
