Or "The fact is that we can't account for the lack of warming at the moment and it is a travesty that we can't. The CERES data published in the August BAMS 09 supplement on ... shows there should be even more warming: but the data are surely wrong. Our observing system is inadequate."
Heh, I love it when deniers mindlessly repeat that quote. You don't even know what it means, do you? Because if you did, you certainly wouldn't be mentioning it.
You see, we measure how much energy the Sun outputs. And we measure how much the Earth reflects of that energy (its albedo). We also measure how much it radiates, which - if the Earth was at a stable temperature - would be the same as the difference between the first two. Understand so far? That's what the "CERES data" refers to.
What Trenberth is saying is that the CERES data shows there should be far *more* warming than we're actually measuring! When you take into account air temperature increase, melting ice, sea temperature increase, etc etc it *still* leaves a big chunk of energy to account for. Now, any sane person would therefore assume that the energy can't just vanish: it's got to go somewhere that we aren't measuring.
Not the deniers, they think it's all being whisked away by the natural cycle fairies. Or perhaps they just don't understand what it is they're saying and are mindlessly repeating what they read on some blog. Hey, maybe you can tell us. Which is it?
