People in the UK Love Recycling

Some research that was released late last year found that people in the UK really like caring for the environment with recycling being the most popular green practice.

Green behaviours costing the least money and effort are currently the most popular with the British public, despite the fact that 59 per cent of people think that if things continue on their current course we will soon experience a major environmental disaster.

A fuller picture of environmental and other behaviours and attitudes based on the first annual survey of 100,000 individuals from 40,000 households for Understanding Society will be published at a later date.

How CoP-15 Changed the World

Depressed about the Copenhagen Accord? While the action on climate change may have been less than you were hoping for, Worldchanging.com has an article explaining how the conference signaled a different kind of sea change. According to Alan Akisson, this was the first major event where developing nations had voices as loud as the developed, in a truly democratic process.

The Earthquake in Copenhagen truly marked the end of one historical era, and the beginning of a new one. It is an era of more democratic global governance (at least in the sense of how power, actual and perceived, is dispersed among nations). An era of continuous struggle to understand what is happening to our planet, and continuous effort to share that understanding. An era of nations being forced to collaborate, more and more closely, and over several decades, on planetary management. In the hindsight of future history (especially environmental history), CoP-15 will likely loom large indeed as an inflection point, a time when everything changed — or rather, was finally seen by all as changed.

How California Tracks the Air That They Breathe

California has a law that dictates the quality of air, but that needs to be tracked so it can be enforced. Here’s a video about how Berkeley Lab keeps track of the air.

Last March, Lawrence Berkeley National Laboratory scientist Marc Fischer boarded a small airplane loaded with air monitoring equipment and crisscrossed the skies above Sacramento and the Bay Area.

Instruments aboard the aircraft measured a cocktail of greenhouse gases: carbon dioxide from fossil fuels, methane from livestock and landfills, nitrous oxide from agriculture, and industrially produced gases such as refrigerants.

The flight was part of the Airborne Greenhouse Gas Emissions Survey, a collaboration between Berkeley Lab, the National Oceanic and Atmospheric Administration, and the University of California, Davis to pinpoint the sources of greenhouse gases in Central California.

The airborne survey is intended to improve inventories of the state’s greenhouse gas emissions, which in turn will help scientists verify the emission reductions mandated by AB-32, the ambitious legislation passed by California in 2006 to slash the state’s greenhouse gas emissions 25 percent by 2020.

“In order to comply with AB-32, we need to know where the gases are coming from and how much,” says Fischer, a scientist in Berkeley Lab’s Environmental Energy Technologies Division.

Wind Turbines are not a Health Risk

A small group of people have complained and argued that wind turbines can cause health problems. A new study confirms that those people are wrong and in fact wind turbines are not a health risk at all.

The study acknowledges that a minority of people find the intermittent swooshing noise emitted by the turbines’ giant blades to be annoying, but it also concluded: “Annoyance is not a pathological entity.”

The study says there’s “nothing unique” about the noise or vibrations emitted by wind turbines and no evidence that the audible or sub-audible sounds have any direct adverse effect on health.

It suggests that those who are bothered by turbines simply have a lower tolerance for annoying sounds of all sorts.

“A major cause of concern about wind turbine sound is its fluctuating nature. Some may find this sound annoying, a reaction that depends primarily on personal characteristics as opposed to the intensity of the sound level.”

What You Can do to Stop Climate Change

Here’s an example of what a German family are doing to lower their environmental impact and make the world a little better for their children:

Georg Fürtges’s pride and joy is a green monstrosity standing in the basement of his house in the western German city of Essen, hissing quietly and consuming dark little pellets that look like worms. The pellets, stored in bins reaching up to the ceiling in another room, are made of compressed sawdust. And the monstrosity is a furnace that is at least three times as big as a modern condensing gas boiler. Fürtges, 55, and his wife Karla, 49, have 6.4 tons of the pellets stored in their basement, enough to meet their heating needs for a year and a half. The couple has decided to live in an environmentally friendly way.
They have been doing so for more than 20 years, partly because they have three children and are thinking ahead, beyond their own life spans. They have made mistakes, but they have also learned a lot. They remain convinced that their approach is the right one, but they also know that a life devoted to living green can only be had at a high price. Georg Fürtges spent an entire year researching heating systems before he recently replaced his old gas furnace with a pellet furnace combined with a solar thermal heating system. Some of the pipes in the house had to be replaced. All told, it cost Fürtges €27,000 ($40,200) to retrofit his home. He would have paid about €10,000 for a modern gas furnace.

“We believe that it will pay off in the long term,” says Karla Fürtges. The couple bought their small 1930s house in Stadtwald, an Essen neighborhood, 16 years ago. The heating system was old, the windows weren’t insulated and the house lacked effective heat insulation.

The couple began by insulating the outside walls. Then they purchased the costly new gas furnace and had vinyl thermopane windows installed. The insulation alone brought down their annual natural gas consumption from 22,000 to 12,000 kilowatt hours. An average household currently consumes almost twice as much gas.
