Performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle for a cup of tea ... a typical search generates about 7g of CO2. Boiling a kettle generates about 15g.
In what math system does 46.7% equal "about the same amount?!"
Let's look at it the other way. Assuming these numbers are correct (I'm not- it's just for the sake of argument), if this scare report caused 50% of the world's searchers to stop using Google, then the amount of CO2 per search would double. Conversely, if twice as many people searched on Google, the carbon footprint would be half of what it is now.
The obvious conclusion from this "research" is that people should search MORE on Google to help stop global warming!
