Arctic Sea Ice Is Rapidly Melting, But Some Of It May Be Normal

While scientists who study climate change know that humans are having an impact on the planet, and that the Arctic is rapidly warming faster than the rest of the planet and losing its sea ice, they’ve had a hard time figuring out some of the connection between warming and sea ice melt.
But researchers may have found out how much melting is due to humans, and how much is due to natural cycles, according to a new study in Nature Climate Change. The researchers determined that about 30 perce
