Do you believe in global warming? What effect has climate change had in your life?

"Believe in"? I'd prefer to say that 25 years of evidence strongly supports the hypothesis of anthropogenic global warming, and that we are at the point where we really should be taking steps to avoid worse global warming. It's a question of science and evidence; belief has little to do with it. Unfortunately, by the time we feel major effects of global warming - such as flooding of many sea level cities - it'll be too late to fix. It's a case where an ounce of prevention is worth a TON of cure.
