Hurricane boost ‘due to warm sea’

Hurricane Jeanne over Florida, September 2004

Hurricanes have become more frequent over the past century

A new analysis of Atlantic hurricanes says their numbers have doubled over the last century. The study says that warmer sea surface temperatures and changes in wind patterns caused by climate change are fuelling much of the increase.

Some researchers say hurricanes are cyclical and the increase is just a reflection of a natural pattern.

But the authors of this study say it is not just nature – they say the frequency has risen across the century. (more…)

Military Sharpens Focus on Climate Change

A Decline in Resources Is Projected to Cause Increasing Instability Overseas

The U.S. military is increasingly focused on a potential national security threat: climate change.

Just last month the U.S. Army War College funded a two-day conference at the Triangle Institute for Security Studies titled “The National Security Implications of Global Climate Change.” And tomorrow, a group of 11 retired senior generals will release a report saying that global warming “presents significant national security challenges to the United States,” which it must address or face serious consequences.

The 63-page report — which is being released a day before the U.N. Security Council holds its first-ever briefing on climate change — lays out a detailed case for how global warming could destabilize vulnerable states in Africa and Asia and drive a flood of migrants to richer countries. It focuses on how climate change “can act as a threat multiplier for instability in some of the most volatile regions of the world,” in part by causing water shortages and damaging food production.

The study’s authors, along with several other national security experts, confirmed last week that the military has begun studying possible future impacts of global warming with new intensity.

It’s only in the last six months that climate change itself has surfaced as a term that’s commonly recognized as having security implications,” said Kent H. Butts, a professor of political military strategy at the War College’s Center for Strategic Leadership. Butts added that when he meets with military leaders to discuss how to tackle terrorism and regional instability, “Each time they’re saying, ‘This is getting worse because of changes in the climate.’ “

Commissioned by the Center for Naval Analyses, a government-funded think tank, the report boasts a list of contributors that includes eight retired four-star generals and three three-stars. Many have significant technological expertise, and some, such as Admiral T. Joseph Lopez, are close to Vice President Cheney. Others, including Gen. Anthony C. Zinni, have criticized President Bush in recent years.

The Army’s former chief of staff, Gen. Gordon R. Sullivan, who is one of the authors, noted he had been “a little bit of a skeptic” when the study group began meeting in September. But, after being briefed by top climate scientists and observing changes in his native New England, Sullivan said he was now convinced that global warming presents a grave challenge to the country’s military preparedness.

The trends are not good, and if I just sat around in my former life as a soldier, if I just waited around for someone to walk in and say, ‘This is with a hundred percent certainty,’ I’d be waiting forever,” he said.

Waxman Introduces the Safe Climate Act of 2007

// July 29th, 2007 // No Comments » // Tipping Point



Press release: “Today Rep. Henry A. Waxman, together with over 125 House colleagues, introduced the “Safe Climate Act of 2007.” The legislation is based on what scientists have concluded the United States must do to avoid dangerous, irreversible warming of the planet and would significantly reduce U.S. emissions of greenhouse gases. “Summary of the Bill: “The Safe Climate Act freezes U.S. greenhouse gas emissions in 2010, at the 2009 levels. Beginning in 2011, it cuts emissions by roughly 2% per year, reaching 1990 emissions levels by 2020. After 2020, it cuts emissions by roughly 5% per year. By 2050, emissions will be 80% lower than in 1990. These goals are comparable to emissions reduction goals adopted by many states and called for by leading American companies, small businesses, religious organizations, environmental advocates, and others.”Resources:
