Hello. We are 3 boys who writes about global warming for a school project, and we would like to hear your opinion about; Whethever you think it is caused by the humans or whether it is just a phase in the Earth's cycle. And who/what do you think, is the cause of global warming. About what you might have heard of options for how to lower the temperature, or stop the global warming. We surely like to hear your point of view and comments about global warming, and also like what you thought of COP15. We go ahead with the project in 2 weeks, so have some time to think about it. Best regards Frederik, Nichlas og Michael.
