It's been a really hot summer. does that mean the climate is changing? options: yes, an unusually hot summer indicates global warming. no, climate change involves at least one winter and one summer. no, climate change involves a much longer time period. this is just the changing weather. yes, the change in weather is the same as climate change.

I would say the first option. each year i've found it to actually become hotter each summer and colder each winter; the massive amounts of rain.

///Yes, an unusually hot summer indicates global warming.///

answer : haversian
