Climate cureIt sounded like a panacea for climate change: “geo-engineering” the atmosphere to block some sunlight and counter global warming. Now scientists scrutinizing the approach say it could produce dangerous cascade effects, severely disrupting weather and agriculture—and might fail to block the worst of the greenhouse effects anyway.

Two prominent climate scientists raised the possibility of geo-engineering in 2006, and it’s been invoked as the world’s emergency escape hatch ever since—a quick fix to stabilize or even reverse the heating of the planet. It would head off worsening heat waves, droughts, and rising sea levels. The estimated price is right, too. A 2009 analysis found that geo-engineering would cost only $2 billion or so a year, chump change compared with converting from CO2-producing coal, oil, and natural gas to wind, solar, nuclear, and biofuels.

More Critical Than Ever by Senator Edgardo Angara

MANILA, Philippines – For the first time in two years, crude oil prices in Africa and Asia broke the $100-per-barrel barrier, threatening many countries’ steady recovery from the global economic and financial crisis.

Filipinos will be hit by the oil price increase where it hurts the most — food and commodities that will become more expensive because of skyrocketing transport costs. In fact, we are already feeling the effects of rising fuel pump prices. Public transportation will cost more after the approved increase in taxi fares and the planned application for fare hike by jeepneys and buses.

MANILA, Philippines—The world is finally coming to terms with an inconvenient truth.

Across the globe, leaders are waking up to the fact that global warming is a real threat. And its impact is palpable, often immediate—disasters and human suffering carried live on television or the Internet almost as they occur.

Last month, as the United States prepared for Christmas, its East Coast was buried under the avalanche of gale-force blizzards. This record snowfall was a reprise of a wintry assault that devastated major cities in the mid-Atlantic region in February last year.

In July last year, an intense heat wave spread from Maine to Pennsylvania. By the following month, the continuing drought shrank Lake Mead, America’s largest reservoir in Nevada and Arizona, by a significant margin.
