We also know that we are in the driver’s seat for these changes. Our burning of oil, coal, and natural gas – fuels that have been extracted from fossil reserves buried in Earth’s crust – is changing the composition of the atmosphere. Greenhouse gases constitute a tiny fraction of the atmosphere, but their ability to trap heat has made the difference between Earth being a frozen ice-ball of a planet and the relatively balmy one we inhabit. Greenhouse gases do this by preventing heat from escaping to space, just as a blanket tucked around a child at night keeps her warm. We are adding to this greenhouse gas blanket, and earth is warming up.
