Check out that freshly-placed button over there in the right column — you know, the one that reads "My Blog Fights Climate Change." That means this little captain's blog here is responsible for offsetting 350 pounds of carbon, in cooperation with the kindly Brighter Planet and 350.org campaigns. According to Brighter Planet, "that's like flicking off 100 light bulbs for a day, or going two full weeks without your car."
If you're not sure what a carbon offset is, the technical definition is clogged with legalese, but at the root, it means someone out there is running a project meant to reduce greenhouse gas emissions, and if you've purchased or otherwise spawned a carbon offset, you've decreased the amount of greenhouse gases emitted into the Earth's atmosphere.
Whether you believe global warming is a problem isn't the issue, either. We humans are fallible, with limitations to our understanding of how we impact the world and the people around us. The world is a complicated place. But it's a reasonable, logical, testable idea that if we change something, it will bring about change elsewhere. And the global increase in carbon emissions as cultures across the world adopt new technologies is definitely a change.
So until we do understand exactly how our carbon emissions are affecting the world we live in, it makes sense to minimize them.
If you want to help, you can visit the 350 Challenge and get your own badge, and your own carbon offsets. All you need is a blog and a little willingness to contribute to positive forward motion and thoughtfulness.
