@flimsin @krishgm @IPCC_CH @Channel4News Dr. Edwards, the AR6 concepts of "Transient Climate Response to cumulative CO2 emissions" (TCRE) & "Remaining Carbon Budget" (RCB) are based on the premise that, not merely does CO2 in the air cause warming, but that the mere MEMORY by Gaia, of CO2 formerly in the air, ALSO does. Image
@flimsin @krishgm @IPCC_CH @Channel4News In fact, the definition of TCRE presumes that CO2 which was once in the atmosphere, but has been removed by natural negative feedbacks like "greening" and dissolution into the oceans, still has JUST AS MUCH warming effect as CO2 which remains.

@flimsin @krishgm @IPCC_CH @Channel4News They justify it by noting that two things which have both been increasing for the last 170 years are therefore correlated, and then concluding (with "high confidence") that means one causes the other — even though there's no physical mechanism by which it COULD cause the other.
@flimsin @krishgm @IPCC_CH @Channel4News It is every bit as ridiculous as blaming bedsheet strangulation on cheese consumption.

@flimsin @krishgm @IPCC_CH @Channel4News You can read about TCRE in AR6 WG1 5.5, TS.3.2.1, 1.6.3, etc., and it's also referred to in AR6 SYN 3.3.1:
ipcc.ch/report/ar6/wg1…
report.ipcc.ch/ar6syr/pdf/IPC…
ipcc.ch/report/ar6/wg1…
(or search the various Reports for the word "cumulative")
@flimsin @krishgm @IPCC_CH @Channel4News Or do you think the TCRE / RCB nonsense is defensible?

Do you acknowledge that it is crackpot pseudoscience (because CO2 can no longer have a warming effect after it has been removed from the air)?
@flimsin @krishgm @IPCC_CH @Channel4News BTW, on my web site yours is one of the blogs which I recommend, here:

@QuincyInst @WilliamHartung 1/25》Which "ravages of climate change" are you thinking of, precisely?

Sea-level rise?
sealevel.info/learnmore.html
I presume not, since sea-level trends haven't significantly accelerated. I trust that's obvious from this graph, of the highest-quality mid-Pacific measurement record:
@QuincyInst @WilliamHartung 2/25》The Dutch have done an especially good job of measuring sea-level (for obvious reasons). Here's one of their best measurement records:

@QuincyInst @WilliamHartung 3/25》Here's that measurement record juxtaposed with a photo of one of their famous dikes. A farmhouse in the picture gives a sense of the scale:

@JKSteinberger 1/11」 Prof. Julia Steinberger, do you believe that because you trust everything AR6 says? I was a WG1 Expert Reviewer, and I tell you that's a BIG mistake.

E.g., have you heard about AR6's new TCRE (Transient Climate Response to cumulative carbon-dioxide Emissions) concept?
@JKSteinberger 2/11」You can read about TCRE in AR6 WG1 5.5, TS.3.2.1, 1.6.3, etc. It's a completely nonsensical concept, based on the premise that, not merely does CO2 still in the air have a warming effect, but that the mere MEMORY by Gaia, of CO2 which WAS ONCE in the air, ALSO does!
@JKSteinberger 3/11」I'm not joking. I wish I were.

In fact, the definition of TCRE presumes CO2 which was once in the atmosphere, but has been REMOVED by natural negative feedbacks like "greening" and dissolution into the oceans, still has JUST AS MUCH warming effect as the CO2 which remains.

@dennishoening @theAGU 1/8」There is no evidence that "with increasing cumulative CO2, land and ocean carbon sinks become less effective (in relative terms)."

You might have been misled about that by Wang et al (2020). I discussed it here:


Compilation:

@dennishoening @theAGU 2/8」There's no reason to think that marine sinks will diminish. As I pointed out, it will be a thousand years before carbon absorbed at chilly high latitudes reemerges in the tropics.
@dennishoening @theAGU 3/8」Moreover, as CO2 levels rise, marine biological sinks are accelerating even more dramatically than expected.
