To the extent that this abrupt cooling event can be identified with ocean dynamics, regardless of whether it involves the GSA or an abrupt change in the intensity of the AMOC, it provides a plausible explanation of why the NH warmed less rapidly from around the time of the end of WW II to 1980 than the SH.

Some climate denialists continue to try and argue that rather than with a steady man - made warming signal, the data are better fit with abrupt step changes caused by El Niño events, followed by flat periods.

It is a fact that there are cyclic warming and cooling events (periodicity 1400 years plus or minus a beat timing of 500 years) in the paleo record and roughly every 8000 years to 12,000 years the cooling is abrupt and there is a larger magnitude change.

Those abrupt global warming events were almost always highly destructive for life, causing mass extinctions such as at the end of the Permian, Triassic, or even mid-Cambrian periods.

The step up in average temperatures during the ENSO cycle looks a lot more like a chaotic abrupt event than it does like CO2 induced warming.

Warming from CO2 has dropped to the bottom of my list of potential «Planet Killers» — although from a Gaian point of view, there are so many interacting challenges to the biosphere now, who knows what kinds of cascades could trigger some kind of abrupt warming or cooling event — maybe not stemming froWarming from CO2 has dropped to the bottom of my list of potential «Planet Killers» — although from a Gaian point of view, there are so many interacting challenges to the biosphere now, who knows what kinds of cascades could trigger some kind of abrupt warming or cooling event — maybe not stemming frowarming or cooling event — maybe not stemming from GHGs.

of warming and cooling (roughly 0.8 C warming and cooling followed occasionally by (with a super cycle of 2400 years and 8000 years) of abrupt cooling events of 2C to 4C.

The AGW supporters are rightly concerned about climate change, however, the problem is abrupt cooling (the -2 C to -4 C events) not gradual warming.

Paleoclimate records from ice cores, marine sediment cores, and speleothems (stalagmites and stalactites) have demonstrated that abrupt Northern Hemisphere cooling and Southern Hemisphere warming occurred in response to Heinrich events.

The interglacial and the glacial planetary temperature data shows cycles of warming and cooling interrupted by very strong «RCEs» (Rickies) Rapid Climatic Change Events (For example the Younger Dryas abrupt cooling event and the termination of the last interglacial).

Once a temperature threshold is breached, abrupt events follow due to amplifying feedbacks, even within a few years, examples being (1) freeze events which followed temperature peaks during past interglacial peaks due to influx of cold ice - melt water into the north Atlantic Ocean; (2) the Dansgaard — Oeschger warming events during the last glacial period; (3) the Younger dryas stadial freeze and the Laurentian stadial freeze.

As if this were not daunting enough, in 2002 the US National Academies of Science not only endorsed the IPCC's conclusions but produced a new report entitled Abrupt Climate Change: Inevitable surprises, which argued that global warming may trigger «large, abrupt and unwelcome regional or global climatic events» such as severe droughts and fAbrupt Climate Change: Inevitable surprises, which argued that global warming may trigger «large, abrupt and unwelcome regional or global climatic events» such as severe droughts and fabrupt and unwelcome regional or global climatic events» such as severe droughts and floods.
