Sorry if this is just a facetious comment I'm replying to suggesting global warming didn't start until the 1980s. Anthropogenic global warming had been happening ever since fossil fuel emissions became widespread, but it is true that warming probably accelerated around then. One of the contributors, besides more co2 and other greenhouse gases, was a lot of action to reduce sulfate pollution in the 1970s. While sulfates are very harmful to human health and cause acid rain and all sorts of other badness, they were having a slight cooling effect. Also worrying is there are still large countries where sulfate emissions are less controlled, much to the detriment of the people that live there. However those sulfates may still be having a cooling effect, meaning our situation right now may be even worse than it seems with the sulfates still masking some portion of the warming.
