She says, but They say

She says:

There is no more debate. Global warming is due to the polluting greenhouse gas such as carbon dioxide and methane. The dirtiest source of carbon dioxide is coal, the fossil fuel used to provide us with electricity. The other sources are oil and gas, which we use for transportation. Methane from the landfill, dump sites and farms is another greenhouse gas responsible for increasing the earth’s temperature. Humans are the cause, thanks to our unsustainable lifestyle and habits. The fate of our planet rests on each one of us for the solutions. But time is of the essence. We need to move fast.

They say otherwise here, here, here.  I'd put my trust in these climate scientists than a ... a lawyer?
