This helps to put things in perspective

We have had solar power technology since the 1800s. Early forms were concentrators that powered steam engines. Now we have advances in materials science, engineering, etc.

This image shows how much surface area it would take to power the World, Europe and Denmark, with current solar panel technology.

Contrast that with estimates of how much land has been ruined by tar sands, mountain top coal mining, toxic waste, etc.

Another thing to compare to would be the rough estimate of the reflective surface area required to counter the warming caused by green house gas pollution. Hint: It’s in the millions of square kilometers and it would need to be done in space.

It’s obvious to me that the Solar, Wind and other renewable energy technologies could easily do the job of providing power for our world. It’s just a matter of making the right choices.

Bill Nye Debates Marsha Blackburn

In case you missed the show: This is a short debate between Bill Nye (the science guy) and Marsha Blackburn (politician) that was held on Meet the press. It was a disappointing debate to me. The format was wrong for this and didn’t give Bill Nye nearly enough time to present the evidence in an informative way.

Having debated with deniers in the past, I know that you generally can’t change their minds on the subject. They either deny that it exists, call it a conspiracy or just blow it off as not being a serious problem. However, there maybe some people in the audience that are simply unaware or misinformed about the scientific evidence. In that case, the better you explain it, the more people are likely to accept climate-change as fact.
