Good morning and thanks. 

I feel my students are aware that the climate change are human- caused. When we did our lesson about  Cycles, my students  were able to identify the cause of global warming (their  responses were pollution and smoke from cars/ factories). 

My students were able to talk about the recent situation in Ellicott City as part of their normal conversation. When I asked them, what are some cause of increase flooding, one student said: trash accumulation. Personally, I even asked one of my friends this question: What's in Ellicott City's geographical location has something to do with the flooding? Also, I compared it to my country of origin where floods and typhoons are very common during summer time. However, I am not sure if the entire school is talking about  what had happened in Ellicott City as part of their content.
