Thanks for the info on Mars, but you failed to mention any reasoning for the other planets warming such as Uranus, maybe Neptune's warming.
Because you didn't ask about them. Duh.
The only part of Uranus itself that is warming is its northern hemisphere. Its southern hemisphere is cooling. Why? Because it's becoming freaking spring on Uranus. This is the pathetic quality of denier "research".
Uranus's moon Triton is warming because it's entering its summertime. It's extremely sensitive to albedo variations. Comparing atmosphere-less or low-atmosphere bodies with no oceans to a body with an atmosphere and huge oceanic heat sink is ridiculous, because there's such a huge difference in thermal inertia, so small changes have greater effects on the former.
Neptune is also entering spring, and is experiencing the exact same thing as Uranus -- one hemisphere warming while the other cools.
I can tell by your line of argument that you believe in one of the dumbest denier lines -- the "solar output is increasing!" argument. Right. The sun is changing without us noticing it. The freaking sun, the most intensively studied object outside of Earth. We watch it from all over the surface, from satellites in orbit, from satellites at the Lagrange points -- but it's sneakily warming everything without us noticing! That tricksy sun!
Can you see how ridiculous that argument is?
There's an entire chapter in the IPCC report about solar variation, which cites the current research papers on solar output and its impact on Earth. Dozens of them. Please read them. Need links? If you'll actually read them, I'd be glad to dig them up for you.
Your statement of consensus of CO2 relating to Global Warming is such example. While CO2 may indeed be a contributing factor, you fail to mention that the factor may be as little as a fraction of a percent.
No, it is not. The forcing from CO2 within its confidence interval dwarfs all other forcings within their confidence intervals. The only one that comes close is methane.
If you keep water vapor in the picture, CO2 is finally in the strong single digits of a percentage of a greenhouse gas present in our atmosphere.
Water vapor makes up about 35-70% of the planet's greenhouse effect, depending on the time of year and weather. Water vapor causes both warming and cooling, as clouds increase the planet's albedo. Water vapor, however, is *not* forcing because it has a very short average atmospheric residency (days to weeks), while CO2 has an very long atmospheric residency (hundreds of years). If you took all of the water vapor out of the atmosphere, we'd be back to normal in just a couple months. In short, the average amount of water vapor-induced warming will always be a response to whatever *other* factors are forcing the climate (along with some random fluctuation -- we call that fluctuation "weather").
In the long term (hundreds of thousands of years), you see the exact same thing with CO2. On the order of hundreds of years, CO2 is forcing. But on the scale of hundreds of thousands of years, it averages out as just a response to other factors -- a feedback. For example, Milankovitch cycles drive Earth's glacial and interglacial periods. However, the amount of forcing they provide is significantly less than the temperature variations between glacials and interglacials. The rest is made up of feedbacks. The warm phase of Milankovitch cycles leads to increased emissions of CO2, amplifying their warming trends.
Another example someone gave was watts per meter. The Earth showed warming of about 1 watt per square meter.
Actually, about 2.4W/m^2, but let's go on.
If you want to picture them as little lightbulbs, picture them inside a vacuum-sealed cooler (our planet drifts in a vacuum).
When you stand next to a fire, do you feel warm because of the radiant energy, or the CO2 being created?
Horrible analogy, for several reasons.
1) Most of the exhaust from a fireplace goes up the chimney, not into the room.
2) CO2 has essentially no effect on such small scales. When you're talking just a couple meters of CO2, it's effectively transparent. If you want to talk *miles* of CO2, however, that's a different story.
3) A much closer example in your analogy would be your home's insulation. The fire is playing the role of the sun, and the home's insulation is playing the role of the planet's atmosphere at slowing heat loss. It's still not a perfect analogy, but it's much closer.
