I’m doing a case study on if the greenhouse effect causing global warming is fact or fiction. I’ve got loads to back up the fact that it does but can’t find any other possible reasons for global warming. Help?
all the things about cars and stuff causing global warming.. is that still the greenhouse effect or something different?
News and comments on global climate change, global warming and greenhouse effect
There are a lot more things contributing to Global Warming than just man. Man has some impact and it’s not simply CO2 emitions – cutting down trees in the amazon doesn’t help. However, if you look at a lot of ‘other’ websites that don’t buy into the so-called ‘hoax’ then you will find that there are statistics pointing towards a natural cycle over millions of years…there’s a couple of good resourses on the site listed below – one ‘link’ at the bottom of the page has a whole list of ‘fors’ and ‘against’ articles and is a great resource – there’s also a ‘wikipedia’ article on the subject..
CO2 from Nature, YES, Nature. not humans
such as Animals, Volcanoes.
Then there are heated water vapors that contribute also.
go to the wiki page on Milankovitch cycles to get an idea of the gross inputs and feedbacks that affect global climate and also the uncertainties involved.
What isn’t discussed is how the continent layout and ocean circulation restrictions appear to also have a role (these two factors affect how the heat is distributed around the world), as well as the effects of ice cover in solar reflection.
One of the problems is that how the climate is controlled in actuality is really not all that well understood. In gross terms, there is a pretty good idea of the important factors. It is how these factors play together to produce climate variability that is the big question. Anthro warming proponents emphasize greenhouse effects as dominant over the short term. It isn’t clear that that is actually the case, but it is the essence of the argument that they present.
I don’t think I would characterize the idea that recent global warming is mainly caused by man as either a fact or a fiction. It is one possible explanation, one possible interpretation of the available data in terms of a poorly understood and very complex system.
Not mentioned in your case is whether antro global warming is necessarily a good or bad thing. That opens up a whole different set of questions. For example, it may be that in the absence of our (man’s) inputs to climate, things would have gone and would be going fairly rapidly in the other way, towards cooling, glacial expansion, and so forth (return to the ice age), and thus warming may actually be the lesser of two evils.
I think it is very important to point out that the climate is not static. It does not stay the same for long. It will change to warmer or colder and tends to cycle back and forth, sometimes fairly severely. People that scream about the horrible warming tend to operate under the false premise that without man, there would have been no climate change. This is emphatically a false presumption.
Not sure if that helps you or not.

Wow, you all sound so credible when you say ‘earth has these natural cycles etc’ and then cite Wiki. Please excuse my sarcasm. My advice is never (ever) to use Wiki, especially in academia. Good luck with your studies. May I repeat, never use Wiki.
