True. its being referred to as climate change now rather than global warming. Global warming is only a part. There's also a global cooling effect !

But we'll ve to be responsible citizens and not throw garbage or burn/use plastic etc. you know all that. Any why it's complex is the nature of the subject. Lot's of parameters, less and more complex. And added to that, there are some data which ( in my opinion ) not fall into the category of being a parameter at all and are purely dependent on historical data.. e.g. behaviour of El nino, La nina etc.. It makes it all but impossible to make projections/calculations about future climate. That's where the public data sets come into the picture. The algorithms are quite complex ( but not difficult or impossible ) and not very accurate. We can only arrive at approximations most of the time. FOSS world needs more people to be involved.. Someone should start a project based on this.. I would suggest we follow the pattern followed by open street maps for such a project.
