Lexington - Lexington native Bill McKibben, on his 350.org Web site, says, “350 is the red line for human beings, the most important number on the planet.
“The most recent science tells us that unless we can reduce the amount of carbon dioxide (CO2) in the atmosphere to 350 parts per million (ppm), we will cause huge and irreversible damage to the earth.” (CO2 levels in the atmosphere are now at about 387 ppm, up almost 40 percent since the industrial revolution and the highest for at least the last 650,000 years.)
The Lexington Global Warming Action Coalition (www.lexgwac.org) is joining McKibben’s international 350 movement with its own Lexington 350 initiative: A call to action to all who live and work in Lexington to reduce greenhouse gas emissions and help halt global warming.
In a recent talk in Concord, McKibben emphasized that it is important for each of us to cut our own carbon emissions through energy efficiency and conservation measures.
Look for this column in future issues of the Lexington Minuteman to pick up ideas and useful facts to help you move forward in doing your part to reduce the human impact on our planet’s climate. Starting with this holiday season, we urge you to switch to LED holiday lights.
Switch to LED holiday lights
It’s a fact: If 50 percent of Lexington households were to replace their traditional holiday lights with LED lights (assuming a fairly conservative three strings on the tree and four strings outside and running the lights six hours per day starting one week after Thanksgiving and going through New Year’s), we would collectively save:
$40,000 in electricity costs
270,000 pounds of CO2
LED holiday lights are widely available this year, at reasonable prices. These very long-lasting and unbreakable bulbs use 85 percent less electricity.
We can be proud that the Town of Lexington has switched to LED lights for its holiday lighting.
