From The Guardian, April 9:

Rising food prices could spark worldwide unrest and threaten political stability, the UN's top humanitarian official warned yesterday after two days of rioting in Egypt over the doubling of prices of basic foods in a year and protests in other parts of the world.

Sir John Holmes, undersecretary general for humanitarian affairs and the UN's emergency relief coordinator, told a conference in Dubai that escalating prices would trigger protests and riots in vulnerable nations. He said food scarcity and soaring fuel prices would compound the damaging effects of global warming. Prices have risen 40% on average globally since last summer.

"The security implications [of the food crisis] should also not be underestimated as food riots are already being reported across the globe," Holmes said. "Current food price trends are likely to increase sharply both the incidence and depth of food insecurity."

He added that the biggest challenge to humanitarian work is climate change, which has doubled the number of disasters from an average of 200 a year to 400 a year in the past two decades.

As well as this week's violence in Egypt, the rising cost and scarcity of food has been blamed for:

· Riots in Haiti last week that killed four people

· Violent protests in Ivory Coast

· Price riots in Cameroon in February that left 40 people dead

· Heated demonstrations in Mauritania, Mozambique and Senegal

· Protests in Uzbekistan, Yemen, Bolivia and Indonesia

Earth in crisis, warns NASA's top climate scientist
WILMINGTON, Delaware — Global warming has plunged the planet into a crisis and the fossil fuel industries are trying to hide the extent of the problem from the public, NASA's top climate scientist says.

"We've already reached the dangerous level of carbon dioxide in the atmosphere," James Hansen, 67, director of NASA's Goddard Institute for Space Studies in New York, told AFP here.

"But there are ways to solve the problem" of heat-trapping greenhouse gases like carbon dioxide, which Hansen said has reached the "tipping point" of 385 parts per million.

In a paper he was submitting to Science magazine on Monday, Hansen calls for phasing out all coal-fired plants by 2030, taxing their emissions until then, and banning the building of new plants unless they are designed to trap and segregate the carbon dioxide they emit.

The major obstacle to saving the planet from its inhabitants is not technology, insisted Hansen, named one of the world's 100 most influential people in 2006 by Time magazine.

"The problem is that 90 percent of energy is fossil fuels. And that is such a huge business, it has permeated our government," he maintained.

"What's become clear to me in the past several years is that both the executive branch and the legislative branch are strongly influenced by special fossil fuel interests," he said, referring to the providers of coal, oil and natural gas and the energy industry that burns them.
