How will climate change affect the Sahara?

Wall Street Journal: At the end of the last ice age, about 11,000 years ago, northern Africa became a grassland, home to fish, elephants and thousands of people. Then, 5,000 years ago, scientists say, it abruptly turned into an enormous wasteland--the vast desert that we now call the Sahara. The shift from savanna to sand was the result of natural climate change, triggered by a cyclical alteration in the sun's orbit. The decline in rainfall pushed residents south and east and perhaps contributed to the rise of the Egyptian...

Earth head toward another mass extinction

Al Jazeera: Species are now disappearing at a rate of up to 1,000 times faster than they did before humans started walking the earth, a new study says. “The Biodiversity of Species and their Rates of Extinction, Distribution, and Protection” was published Thursday in the journal Science, and it warned that the world is on the brink of its sixth great extinction. Mass extinctions have wiped out the majority of life on Earth at least five times. About 66 million years ago, a mass extinction killed off the...

Greens plan huge push President Obama climate plan

Politico: President Barack Obama's new climate rule is getting a major push from his green allies, who plan to blitz the airwaves next week with the start of a summer-long campaign to champion the administration's attack on carbon. Obama's fiercest critics, meanwhile, are largely holding their fire for now. That means environmental, public health and religious groups may be waging a mostly one-sided publicity onslaught -- at least in nationwide paid media -- after the White House and the EPA unveil their...

Oilsands: Desmond Tutu stresses quick action against controversial project

But he told reporters in the northern Alberta oilsands city that the world is sitting on a powder keg if something isn’t done quickly. Tutu is in Fort McMurray for a two-day conference on aboriginal treaties and climate change. The archbishop, who won the Nobel Peace...

Why Natural Gas is a Bridge to Nowhere

EcoWatch: Though the president and federal Environmental Protection Agency are on the brink of issuing new rules for existing coal-fired power plants, a Cornell University professor says natural gas deserves a bit of attention, too. Robert Howarth has maintained for three years that natural gas was capable of emitting more greenhouse gases than coal. Now, the professor of ecology and evolutionary biology has new research to back it up. Published in the Energy Science & Engineering journal this month,...

World ‘On The Brink Of A Sixth Great Extinction’

Design and Trend: A new study has revealed that plant and animal species are becoming extinct at least 1,000 times faster than they did before humans entered the picture. The study claims the world is "on the brink of a sixth great extinction" The study compared past and present rates of extinction, and found a lower rate of extinction in the past than scientists had thought. Species are in fact disappearing from the planet about 10 times faster than previously believed. Stuart Pimm of Duke University, and...

UK Weather: spring set to be third hottest on record

Blue and Green: The Met Office has predicted that this year’s spring will be the third warmest on record in the UK.

Record low river flows show need for improved water planning

Banner-Herald: There’s not as much water in the Oconee River as there once was, and there’s going to be less in the future, according to a Georgia Tech professor’s study. The amount of water going down the Oconee River has declined about 20 percent in the past 50 years, according to Aris Georgakakos, director of the Georgia Water Resources Institute at Tech. He’s recorded similar declines in the Chattahoochee-Flint and other Georgia river basins. And the declines area likely to be even steeper in coming...
