Tipping Points in the Ocean and Atmosphere Global Circulations

Ғылым және технология

I chat here about the latest science on tipping points in the dynamic fluid systems of the Earth, namely the ocean circulation patterns and the atmospheric circulation patterns.
The most recent key review document containing this knowledge summary is “Global Tipping Points 2023”: global-tipping-points.org/
The key ocean current systems that are presently showing early warning signs of rapid approach to tipping points include the Atlantic Meridional Overturning Circulation (AMOC), the Subpolar Gyre (SPG) and the Antarctic Southern Circulation systems.
There is a huge risk that as the slowdown and even stoppage of some of these global ocean circulation systems proceeds, the monsoonal rainfall in the tropics from the Intertropical Convergence Zone (ITCZ) will all change, as the ITCZ would shift southward, so the existing monsoonal patterns would all shift, with the existing monsoonal regions getting much drier as the rainfall falls in regions further to the south. Clearly, this would impact millions to hundreds of millions to even billions of people in these regions.
Also, changes to the atmospheric circulation are examined, with the conclusion (in the review paper) essentially being that the shifts are not likely to exhibit tipping behaviour (don’t think I agree).
Also, effects on the ENSO (El Niño Southern Oscillation) to a more “permanent El Niño state) are discussed.

    Another problem potential relating to the cutting of sulphur from ship fuel that I have realised: with less sulphur entering the ocean, there would presumably be be a reduction in DMS (dimethyl sulphide) produced by algae and phytoplankton? And DMS is a very powerful feedback promoting cooling. If algae and phytoplankton increasingly shut down due to shoratge of sulphur, that is potentially up to 45% of the global sink of CO2 gone. Do we urgently need to put sulphur back into ship fuel?

    Are there any measureable metrics giving an early warning of algae and phytoplankton shutting down? For example, is the oxygen in the oceans surface reducing now relative to previous to the ban on sulphur in ship fuel?

    Thx Paul This is a very useful summary of the global situation...very useful in understanding where the trouble will come from and how it will affect the overall system. I'm starting with the Amazon, then maybe the AMOC/Gulfstream. However before then the heatwaves and extreme weather events will have caused devastating problems for humanity/civilisation. $10 coming your way. Please keep on your reporting here and with climate emergency forum podcast. Thx again

    One study has found that when subpolar gyre gets more melting waters, the Golf stream gets stronger and winds toward Greenland. This explains why Europe has had these extreme heat events and even allows to predict them in the wintertime months before the summer heat. Golf stream change also affects the jet stream.

    It is unlikely that there will be a WW3... Even though political circumstances globally are dire ... Biospheric shift of homeostasis is likely to extirpate all extant organism - certainly surface and pelagic species - in short order. AGW and other 'vectors of doom' are likely to make a global - nuclear - confrontation very awkward to implement anyway.

    At 3:13 it was explained that the Sahara region at various times in the past had experienced what is formally referred to as "pluvial" (noticeably rainier) phases. The same is true for the Arabian Peninsula. There were times during the past half million years that the southern Arabian Peninsula had a few lakes that were roughly 10 kilometers across. Such a pluvial phase seems to be about to happen again in the Arabian Peninsula. The surrounding ocean is trending warmer, resulting in times of the year with greater absolute humidity, meaning that a low pressure system drifting across the Arabian Peninsula between the Red Sea and the Persian Gulf have more atmospheric water that can become rain. Also, the recent northward drift of the ITCZ during the last century or so increases the chance of a seasonal monsoonal low intermittently setting up in or near the Arabian Peninsula, analogous to the seasonal monsoonal lows that with good enough agricultural reliability set up near Jodhpur in northwestern India and near Ledo in northeastern India. One more impetus to a near future pluvial cycle in the Arabian Peninsula is a broadening of the Persian Gulf due to sea level rise, especially in the southwestern shore of the Persian Gulf. For a given set of sea surface temperature and relative humidity and wind speed conditions, the Persian Gulf will evaporate water into the atmosphere in rough proportion to its surface area in square kilometers.

    @@DrSmooth2000 , you are back! Here I have been less mathematical than I was previously when discussing the overall scheme of Earth's greenhouse effect in the comment section of another KZread channel some months ago (December 2023?), but I still gave what is known as a "scaling approximation" in this KZread channel, the Paul Beckwith channel. One other useful scaling approximation for evaporation rate from a region of sea has to do with windspeed. For a given set of temperature conditions, the rate of evaporation scales approximately in proportion to windspeed. Evaporation also scales approximately in proportion to seawater vapor pressure at the temperature of the sea surface. The temperature trend of the Persian Gulf is upward, so in future decades, faster evaporation rates can be expected in the Persian Gulf. The surrounding hilly and mountainous terrain will tend to squeeze out the additional moisture added by the Persian Gulf to the atmosphere, so higher average annual rainfall can be expected near the Persian Gulf in future decades.

Speculate the low cloud, high heat combination of Sahara today but set over the Med would cause 'pop up' weather events and be sporadic rain. Italy most certainly as a differential between Adriatic and main Sea would precipitate? Or the evaporate would behave some other way? Did I phrase that clearly enough?

    The net result to well north of the Mediterranean Sea, right the way north to slightly into the Baltic Sea coastal states of Germany, would be a lot of year to year variability. Median monthly rainfall, which is an agriculturally substantial metric during growing season months especially where a vast network of reservoirs has not been constructed, would fall percentagewise to well below average monthly rainfall in many parts of Europe north of the Mediterranean Sea. An especially wet month has a noticeable effect on the average for that month, but little effect on the median for that month, if in most years during a particular month, July for example, there is little to no rainfall. Unirrigated grain agriculture during or near the Summer often becomes economically unviable if in three consecutive months there is little rainfall. Forest areas also become especially prone to wildfire in such situations as well. The long term result is likely to be much larger regions of botanical wasteland north of the Mediterranean Sea in Europe, with heavy rain events being able to therefore wash away large amounts of soil, eventually leaving mostly sand and pebbles and rocks behind. Potentially, aeolian (wind driven) erosion could also blow away substantial amounts of topsoil in duststorm events during some years.

    Hey Paul, another interesting video. I was thinking it would be fascinating to get your analysis of more specific regions, the predicted climactic and biosphere changes, and a glimpse into how a region is interconnected with other areas or systems. Like what might we expect for, say, London or Lagos? Various regions in Australia? Of course I’m also curious about my home region of the west coast of Canada 😊

    Can we detect climate change in the types of cloud cover at various times of year? I have noticed peculiar cloud cover in the winter where I am in South Central BC which is more reminiscent of the temperate coastal regions. It makes sense that the cloud formations would change respectively depending on what is going on in the atmosphere.

We are staging climate action against a 6Gt GHG gas project next week, and as a proxy shareholder activist I always look to refer to these peer reviewed impact studies in as many questions I can ask, to challenge the insanity of further new fossil energy developments.

Whether you like it or not, we're in a doomed if you do, doomed if you don't situation. And I'm really not concerned about activists taking down carbon production. Activists like to eat, too.

    I still have difficulty understanding this concept because of geologic time. I think we crossed tipping points 40 years ago the only difference is that instead of seeing it 500 to 1000 years in the future we’re seeing it in a couple of decades, due to rapid increasing GHG emissions during the intervening 40 plus years. Human nature is also funny, if my statement was true, I’m sure we would feel a whole lot better today even though the outcome would be identical.

    Given the manifest 'anthropogenic vectors of doom' in play, on the current trajectory and especially the RAPIDITY of biospheric changes, unprecedented in pretty-much all of Deep Time (Chicxulub excepted).... The Earth's biosphere is shifting - incrementally to human temporality - extremely rapid in geological temporality - towards an alternative state of thermo-equilibrium. The Earth's biosphere exists in one of two states of homeostasis - 'Hot/Greenhouse' or 'Ice-house' - glacial states. Currently we are in an Ice-house state, characterised by the existence of a cryosphere (Ice sheets, continental glaciation, sea-ice, permafrost) but that is changing... No extant organisms are likely to survive in the alternative state. Given those aforementioned 'vectors of doom' in addition, it is quite likely that the current ongoing mass extinction event will be the largest to date; possibly exceeding that of the third MEE - 'The Great Dying' [Permian-Triassic ~250Ma] - whereby around 96% of marine species and 70% terrestrial species became extinct... How much will now perish, given the proliferation of civil nuclear facilities (440+ globally)? If those 440+ reactor facilities end-up releasing vast clouds of ionising radionuclide aerosols to atmosphere, where those aerosols will deplete the extremely thin patches of stratospheric ozone that currently protect the biosphere, which would not have existed without that crucial O3 shield; from the lethal and sterilising effects of solar UV-B/C radiation - effectively sterilising the Earth's terrestrial and marine pelagic ecosystems and decimating the Trophic Order. GAME OVER. Certainly for all large vertebrates - even tardigrades or deinococcus radiodurans - the Earth's hardiest micro organism will perish through lack of nutrients (organic matter) . The only organisms likely to survive are those that have an alternative primary energy source - such as the chemotrophic organisms and the isolated micro-ecosystems they support in the deep subterranean regions, or isolated ecosystems inhabiting the hydro-thermal vent systems situated on the tectonic margins deep in the oceans. At the very least - the current MEE has the potential to revert evolution to pre-Cambrian status - The Proterozoic eon [2.5Ga - 538Ma]. A period characterised by early - prokaryotic (single-celled) organisms. Upshot - NO ONE - HUMAN - WILL 'INHERIT' THE EARTH - EXCEPT PERHAPS THE MEEK AND DIMINUTIVE AFOREMENTIONED ORGANISMS. ===================================================================================================== AnthropoCENTRIC Homo sapiens - '''sapiens''' - Either drunk on hubris, stoned on hopium, or in a coma of denial, or a fug of faith and mostly oblivious to O B L I V I O N. '' I cannot lie to you about your chances (for survival), but... you have my sympathies....'' [SO Ash - USCSS Nostromo].

    - We live in the same climate as it was 5 million years ago - I have an explanation regarding the cause of the climate change and global warming, it is the travel of the universe to the deep past since May 10, 2010. Each day starting May 10, 2010 takes us 1000 years to the past of the universe. Today April 19, 2024 the state of our universe is the same as it was 5 million and 93 thousand years ago. On october 13, 2026 the state of our universe will be at the point 6 million years in the past. On june 04, 2051 the state of our universe will be at the point 15 million years in the past. On june 28, 2092 the state of our universe will be at the point 30 million years in the past. On april 02, 2147 the state of our universe will be at the point 50 million years in the past. The result is that the universe is heading back to the point where it started and today we live in the same climate as it was 5 million years ago. Mohamed BOUHAMIDA.

    As indicated in this paper, some tipping-points have already occurred. Others await in the wings (Arctic BOE etc...)... With many more on the horizon. Some tipping points - eg; depletion of the cryosphere - will take hundreds of years, simply due to the mass of ice that would need to thaw... Especially on Antarctica. The same could be argued for other slow/massive dynamics, such as the Global Thermohaline Circulation [MOC/AMOC] . However, even small perturbations in any of these dynamics have significant ramifications for the biosphere. We see this now unfolding with global warming. So the answer is open.... Some feedbacks and tipping points are slow to show effect, others are rapid (like anthropocentric global warming...)
