You meet someone in another class who expresses skepticism about climate change and global warming. The student explains that weather in their area has been the coolest they can remember that season. Using what you've learned from the climate change chapter, select all the replies that would be accurate to share with your classmate.

-"Global warming" means that the average global temperature is increasing. It doesn't mean that temperatures everywhere are hotter. -Weather and climate are different. Cooler weather in one location does not mean the global climate is also cooler.
