WTF. The Urban Heat Effect is one of the first topics we learned in Urban & Enviro Management. Ha. Also, I'm in Australia, and the Montreal Protocol definitely helped to reduce the human-induced climate change in the ozone. Sunblock is still a must and skin cancer is still prevalent, but addressing environmental degradation works!
The questions I have for climate deniers are; why did Exxon Mobil, governments, and many other businesses, conceal and mislead the public about fossil fuels if there was nothing to hide? And, are polluting rivers, deforestation, dams, overfishing, human settlements, industrial agriculture, intensive natural (finite) resource consumption, ecological destruction, habitat loss, and numerous other human activities considered climate change?
As if humanity tiptoes around the planet, respecting other species. Ha. We definitely don't disturb anything on this planet!
