Tornado in Manhattan, Kansas, 31-May-1949, from NOAAYesterday, an unusually ferocious winter tornado system killed at least 55 people in five Southern states, and destroyed over a thousand homes and businesses. Usually tornadoes touch down for 20 minutes then come back up, but these were rare "long-track" tornadoes that stayed on the ground for 30 to 50 miles.

Lots of recent research indicates that global warming increases the intensity of hurricanes. Could it also affect tornadoes? It’s too early to tell, but scientists are starting to look.

Dangerous CFLs? Don’t Believe Everything You Read

On February 3, Parade published a misleading Medical Alert column with the headline "Bright Lights, Bad Headache?" by Dr. Isadore Rosenfeld. It starts with a list of unsubstantiated claims:

As energy-saving fluorescent lightbulbs become standard, new research suggests some dangers: Flickering bulbs have been reported to precipitate migraines or even seizures, though manufacturers say the new models have been improved. Fluorescent light also can aggravate skin rashes in people with lupus, eczema, dermatitis or porphyria.

Environmental Defense could find no published scientific studies demonstrating that compact fluorescent light bulbs (CFLs) trigger migraines or seizures. And unlike older fluorescent tube lights, modern CFLs with electronic ballasts don’t flicker.

2007: One of the Warmest Years on Record

By Lisa Moore / Published: February 5, 2008

The results are in for 2007, and it was a warm one. How warm? It depends who you ask. According to NASA, 2007 was the second warmest year on record. NOAA’s analysis put it in fifth place. The University of East Anglia’s Climatic Research Unit (CRU) ranked it eighth.

The results differ because it’s not as straightforward as you might think to take the temperature of the globe. There are many subtleties to consider.

Banks Consider Risks in Financing Coal Plants

By Mark Brownstein / Published: February 4, 2008

Mark BrownsteinThis post is by Mark Brownstein, Managing Director of Business Partnerships at Environmental Defense.

A little over a year ago, Environmental Defense, the Natural Resources Defense Council (NRDC), and Ceres sent a letter to the three lead banks financing the TXU deal we helped broker. We said the banks no longer could ignore CO2 in their investment decisions.

Today we are seeing the culmination of this effort. The three banks – Citigroup, J.P. Morgan Chase, and Morgan Stanley – have announced that they will require utilities seeking financing to prove the new plants would be economically viable under an expected federal cap on greenhouse gas emissions.

This will make it much harder for utilities to build conventional coal plants.

Belkin’s Conserve Surge Protector – At the Consumer Electronics Show this month, Belkin showed a new surge protector called Conserve that can shut off six of its eight outlets with a switch, or with a handy remote control (in case you don’t like climbing under your desk). Standby or “phantom” power from devices such as TVs, computers, and battery chargers, can account for up to 20 percent of your electric bill. This device could save you money, as well as reduce your carbon footprint.

Eco-Fashion – It used to be only hippies who cared about natural fibers and sustainably produced clothing, but no more. Now top designers have gotten into the act. One company in Denmark, Earth A’Wear, does nothing but.

NYS Commission Approves Congestion Pricing Plan

NYC - picture by David ShankboneNew York City suffers from some of the worst traffic congestion in the country, costing workers and businesses billions of dollars a year in lost time, and heavily contributing to New York’s nearly worst-in-the-nation air quality. One in eight New Yorkers suffer from asthma. And New York is expected to add one million residents by 2030.

New York State charged a commission of elected officials, and environmental and planning experts with solving New York City’s traffic crisis. Andy Darrell, Regional Director for Living Cities at Environmental Defense, was one of the commissioners. Today the commission voted to approve an historic plan to protect New Yorkers’ health.

A key element of the plan is congestion pricing, where an electronically-collected fee system charges drivers more for using the most congested roads at the most congested times. This encourages drivers to instead use mass transit or to reschedule their trip. Cities around the world are successfully using congestion pricing to reduce traffic and pollution from vehicle exhausts.
