Hi guys its Darko again and today its the finale of the 3 part series about Climate Change! Today’s post is about how do scientists know the climate is changing? Scientists know the climate is changing  because as you can see the Arctic is smaller due to increasing temperatures. Also they have satellites which observe and make lots of measurements, so they know that the climate is about 1.5 Celsius warmer. Thank you for reading this post and I hope you enjoyed. See you in my next post!
