Madam Speaker, there are several different things to unpack in that question. I know the next speaker is going to be this very same member; she knows a great deal about this topic. I hope that, if she does not mind veering away from the prepared text she had, she will share her thoughts on the subject.
With regard to the issue of methane gas, in general, I heartily agree with her that trapped methane gas is very much a real issue. There is a formula that gets tossed around: Methane gas is 21 times as problematic as carbon dioxide. I am never quite sure exactly what that means, but clearly, molecule per molecule, it is a very serious issue.
If we look at human-caused climate change, the cause from humans emitting methane is much more serious than one would think from listening to the popular discourse. There is a very interesting argument to be made. There is a book called Plows, Plagues, and Petroleum. I do not know whether the member has read it, but if she has not, I know she would find it fascinating. The author argues that humans have been causing greenhouse gases to release for far longer than we think, and it started with human rice cultivation, which caused an enormous amount of methane through the creation of artificial swamps.
This is a good area to study for sure. I am out of time to talk about the positive feedback loop, but maybe the next question will deal with that.
