We’ll be off for a few days, so we won’t be posting again until next Thursday. Have a great holiday.

Here’s an interesting way to look at greenhouse gas emissions. The WorldMapper project has assembled hundreds of global maps in which nations are resized according to different variables – for example, total population and carbon emissions:

Two years ago, California asked the U.S. Environmental Protection Agency (EPA) to pave the way for landmark standards to limit global warming from motor vehicles. Seventeen other states plan to implement the Clean Car standards, pending the EPA decision. But today – after two years of stalling – EPA said no. This decision is virtually unprecedented; EPA has granted similar requests over 50 times in 40 years.
The Bush administration is putting the brakes on state action to address the global warming crisis. Doing nothing about global warming is bad enough – but going out of your way to block the state leaders who are taking action is just plain shocking.

All year long we’ve been monitoring developments in climate science, and posting about the important new developments. I thought now would be a good time to look back over 2007 and summarize what we’ve learned.
Here are ten noteworthy science stories we covered in 2007:

Many people idle their car engine in winter because they think it needs time to warm up. Not true! Today’s fuel-injected engines don’t need a warm-up period, and idling for long periods can lead to excessive engine wear.
Worse, cars idling for over 10 seconds use more gas and create more global warming pollution than simply restarting the engine. Surprised? It’s true. The 10-second rule has been proven empirically.
This post is by Martha Roberts, an economist at Environmental Defense. It’s the first of a three-part series on carbon sequestration – storing carbon or carbon dioxide (CO2) in soils, trees, geological formations, and oceans.
1. Biological Sequestration
2. Geological Sequestration
3. Ocean Sequestration
Global warming is occurring because – day after day, hour after hour – human activities pump large amounts of greenhouse gases into the atmosphere. One way to decrease emissions is to store carbon or CO2 someplace other than the atmosphere.
There are two vastly different ways of sequestering carbon: biological and geological. The topic of this post is biological sequestration, which is among the biggest of the "low hanging fruits" for making quick, substantial cuts in emissions.
