So why do you believe Greta? Why is her knowledge much greater than an average person in this? or are you just basing this on feelings and feel bad that this girl was put on a pedestal despite that obviously she knows little to nothing on this and is just a parrot for her parents leftist beliefs. I believe the Sun has always been the greatest determining factor for the climate on this planet. If you look at history you know this is true! Pathetic that anyone would be a Greta Parrot, that parrots her parents beliefs, that is what really is pathetic.
