Please rewrite it and make it free of plagiarism. I just combined them from many sources. So you just rewrite it in your own way and DO NOT paraphrase it but just rewrite in your own words and make it flow. You should use linking words such as in contrast, However, In addition, etc to make it flow and coherent where it needed. You do not change some technical words/terminologies such as retreat, glacier, climate change. You can keep these words.
