Are satellite orbits being compromised by global warming?

As bizarre as this might sound, a new study published in Nature Geoscience is suggesting that global warming is having an impact on objects orbiting around the Earth. According to environmental physicist Stefan Noël, rising carbon dioxide levels are reducing the pull of the Earth's atmosphere on objects like…
