      Thank you for your question! There are so many interesting facts about climate change. As I work on Antarctic biology, I’ll share one related to that region. There’s an enormous ice sheet on the Western side of Antarctica- called the Thwaites glacier, and if it continues melting at the current rate, global sea levels will rise by three metres! That’s a huge increase and will cause lots of flooding around the world and destruction of habitats.

      Here’s a video about the glacier:

      Lots of scientists in Antarctica also drill into the ice to collect long ice cores. They do various bits of chemical analyses on these cores and it can give them a picture of what climate used to be like thousands/millions of years ago. Scientists have found that although the Earth’s climate has varied throughout history, it’s warming at a faster rate now than it ever has. And we know that it’s been primarily caused by humans burning fossil fuels.
