sYes, let me tell you a meaning from the dictionary "a change in global or regional climate patterns, in particular a change apparent from 21st century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
You must be wondering what this is? Well let me tell you the first half of the picture which is titled "BEFORE" means that when there was no climate change people lived peacefully there were trees humans were fine and everything is good to go, there animals there's water and so much more. but the second half of the picture " AFTER" is completely different there's smoke in the air which made the sky gray, humans are no more as there were no trees oxygen was not taken in and they got sick and died the only thing that is left is factories and there is smoke all around. all that is left to say Stop Climate Change.
