Global Warming: Natural Or Man-made?
I think the 'questions' of global warming are mostly related to people who have a vested interest in the world maintaining its status-quo. If we recognize that humans are the cause of global warming and that global warming is not natural and very dangerous to us, then we will have to change it. That means stopping a lot of really powerful businesses from operating the way they have for the past 100-150 years. It means prioritizing people and the environment over the bottom dollar. It means making decisions that benefit people and society without seeing any return on that investment besides there still being a world to operate in some indeterminate amount of time in the future. These are very heavy concepts that are hard for people, much less huge corporations to deal with.
Now as to whether of not global warming is real, I think all you have to do is look at all the data from 100's or 1000's of scientists to see that something is going on. It is not one insular group of scientists and it is not one country, it is every country and most scientists. Of course there is 'evidence' against it, but it is like the 'evidence' against cigarettes causing cancer. It is funded by a pro-status-quo group who doesn't want to change anything and is 'finding' what they want to find. Even if there is one percent of papers coming out saying that they have evidence global warming isn't real, that doesn't mean we should ignore the 99 % that are saying it is.
