@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.

@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:

@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.

@theNASEM @SciCommAwards 1/5》Good grief. Someone pointed out to me this muddled mess from the NAS, which seems designed to confuse teachers and students about what science is:
nap.nationalacademies.org/read/13165/cha…
@theNASEM @SciCommAwards 2/5》The NAS's authors not only apparently don't understand what science is, they explicitly reject it. They wrote:

“A focus on practices (in the plural) avoids the mistaken impression that there is one distinctive approach common to all science—a single 'scientific method.'”
@theNASEM @SciCommAwards 3/5》That's completely wrong. Feynman must be spinning in his grave.
