If reading technical scientific papers on climate change isn't your thing, watch this video, which covers many of the AGW denialist arguments. He explains what should be obvious, that day-to-day temperature is no indication of planet wide trends, and does it with a nice chart of temperature variations in the US, which while famously cold in the east, is almost as inordinately warm in the west. As usual, once one tosses out the cherry-picking, and looks at all of the data, the denialist case vanishes.
He also gives a good primer on the impact of ocean currents, El Nino and La Nina on the temperature we see. Be sure when you view the chart of gobal temperatures @ the 4:15 mark to note the extraordinarily warm year 1998, and how without it, none of the denialists' "it's been cooling for the last 10 years" arguments would be even slightly reasonable. Again, scratch a denialist hard enough, a cherry-picker will always emerge.
Here's a humorous take on global warming. What that it were so.
