[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)
You can also see in this graph that the warming trend in the global data for the low troposphere, if we consider the whole set of data, i.e. from the average between 1980 - 1982 till now, with now meaning the average of the last three years, the warming trend is, AT MOST, 0.115 ºC / decade (0.3 ºC in 26 years), but the graph is going down recently, so it should be even less.

If we multiply that over ten years, and figure that the top billion or so of world population is responsible for the lion's share (say 80 %) of the emissions, could we then conclude that, on average, every member of that top billion (presumably including all on this forum) had contributed the energy equivalent of one Hiroshima bomb (or more) toward atmospheric global warming over the last decade?

(Orbital forcing doesn't have much of a global annual average forcing, and it's even concievable that the sensitivity to orbital forcing as measured in terms of global averages and the long - term response (temporal scale of ice sheet response) might be approaching infinity or even be negative (if more sunlight is directed onto an ice sheet, the global average albedo might increase, but the ice sheet would be more likely to decay, with a global average albedo feedback that causes warming).
So, if each underwater artic volcano emitted 1 km3 a week (a rather large average flow) and did it for a year (about 52 weeks) you would need about 620 very active and extremely powerful volcanoes in order to warm the artic ocean by just 1 C (and that ignores surface cooling, in / out water flows and time rates that would require even more volcanoes.)
