Jeff:

You are entitled to your opinion, just as I am entitled to mine.

By the way – we won’t know if I am wrong until we hit 560 ppm.

He is wrong. We know enough. Most scientists would estimate that virtually all of the recent warming is down to us. More importantly, we don’t have the bloody time to procrastinate. The empirical evidence is piling up showing that climate warming is stressing natural systems, many which are at or near their breaking point. We are seeing serious effects on species interactions, phenology, marine and terrestrial stoichiometry, and terrifying global declines in species of birds, mammals, amphibians, insects, plants and other taxa which at least can be partially attributed to warming.

RickA’s shares aren’t going to be worth jack shit if we don’t get off if our collective asses and act. Reading his gibberish on here I have the repeated urge to hurl.

they say “that to be completely safe, we need to avoid hitting 1C in order to make sure that natural variability doesn’t cause us to exceed 1.5C. 1.5 – 1 = .5C”

But they don’t say that.

Be fucked the ocean has cooled back to anything.
The trend is very fucking clear as a bell.

BBD sez ” Total response to 400ppm to date.. ” and I thank BBD for it.
I think that ” to date ” thingie is not stressed enough in dialog because of the rising CO2 trend and focus on current level or the formulative doubling which is insanely high in reality
What if i posed the query, hows 340 ppm to date looking?
Things take time….

I didn’t introduce OHC – you did.

No, oh physically illiterate tool, you used the words ‘the ocean has cooled back’. That means ocean heat content has fallen. If you meant SSTs, then say SSTs. Don’t pretend that your errors are mine.

I think BBD missing a certain detail in the formula he was using.

Really? Which one?

I know that. I am talking about the observed transient response to 560 ppm (which has not occurred yet).

You are insisting on an irrelevance to avoid admitting that you can see that ECS is going to be close to 3C from current observations. It’s called ‘denialism’.

Is it your theory that some unknown process will make the change from 400 to 560 differ from the 280 to 400 change?

Or are you arguing that the attribution to CO2 is smaller than 100%?
