Re: contrails / chemtrails @FlamingDeath
"The problem most lay-people have is that they think that the Earth's climate should be unchanging if we did nothing."
And we then have two types of not-quite so lay people. Those who think we should do nothing so it won't change and those who think it isn't changing whatever we do. Both are doomed to disappointment: the climate will change irrespective of whatever we do and sea levels relative to land (which I think underlies a lot of concerns) will also change, not necessarily the same way in different places.
