The sceptics say there is no such thing, they say there is no proof.
They say that the glaciers are not melting, sea levels are not raising , and just dispel all the proof as nonsense, and that green house gases are not harming the earth or us.
Countries like America, Canada, China, India who are the biggest consumers of fuels do not believe in it and are doing nothing about, ok, they tinker around the edges a bit.
How long do they think the fuels are going to last, another 50 or 100 years at the most. What doe’s mankind do then.
