Climate change. Admittedly, for some it remains an emotionally charged subject.
Yet among scientists there is general agreement that global warming is caused (mostly) by burning fossil fuels. This adds greenhouse gases to the atmosphere which trap heat energy from solar radiation near the earth’s surface.
So far, slowing down climate change has meant reducing greenhouse gas emissions. But what if that’s not enough? What if we could reduce the amount of solar energy that actually reaches the earth’s surface in the first place?
