Reflections on "Climate change"

It's almost mid-December, but the weather is unbelievably warm compared to before.  I like it that it's not too cold, but at the same time I'm worried about the world's climate change. The main reason of this "warm" weather is because of the global warming, which we, humans, cause the Earth to get hotter by our activities. There have been many international talks to discuss protecting the world's environment and one of them was held in Paris last week, "COP21". It aimed to curb global warming to less than 2C (3.6F) by the end of the century. We all should put our efforts to protect our planet.
