TIA,I think that you have stated a truth in that news writers often do not comprehend what they write about and work from a point of view that a good story sells more papers than some rather dry facts. There are also scientists out there who present a dramatic forecast in the hope of attracting some research grants.
That worldwide temperatures are increasing can be a proven fact. Why they are rising can only be theory, but an educated guess based on research acceptable to the wider scientific community should carry considerable weight. There is no denying that a problem exists, but it is caused by many factors. Increasing CO2 levels is part of the problem and mankind must bear some blame for that, but methane and other hydro-carbons emitted from the earth are a larger problem and that is far beyond our control. If there is too much CO2 in the atmosphere more vegitation should grow to absorb it if the natural cycle is allowed to proceed. If we clear more and more vegitation the natural balance of nature is disrupted so that part is simple enough.
What mankind has put into the equation during this cycle is greed. If somebody dosen't make money on it they don't want to do it. Mother Nature can and will take care of herself but it may be at our peril.
