What is greenhouse gas? And does it include fossil fuels or not? Thanks!
What is global warming ? Will it occur ? What is your opinion ?
I would like to know what common people think about climate change. Do they see any changes in their countrys climate? Or maybe they have suffered the consequences of climate change?
How does the global warming is going to affect our planet? What can we do about it? Is it as real as people say it is?
Is it worth spending the extra $$$ to upgrade to a unit that is Energy Star rated?
