    1. Ausführlicher Bericht über die neue Studie zum Zustand des Amazonas-Regenwalds. Bis 2050 drohen 10-47% einen Kipppunkt zu erreichen, jenseits dessen sie ihre jetzigen Funktionen für Kohlenstoff- und Wasser Zyklen verloren. Die Studie beschäftigt sich mit 5 Treibern für Wasser-Stress. Um den Regenwald sicher zu erhalten, ist der Verzicht auf jede weitere Entwaldung und das Einhalten der 1,5°-Grenze nötig. https://www.theguardian.com/environment/2024/feb/14/amazon-rainforest-could-reach-tipping-point-by-2050-scientists-warn

    1. Langes Interview mit Hans Joachim Schellnhuber im Standard, under anderem zu Kipppunkten und der Möglichkeit, dass wir uns schon auf dem Weg in ein „neues Klimaregime“ befinden. Schellnhuber geht davon aus, dass auch das 2°-Ziel überschritten werden wird. Der „Königsweg“, um der Atmosphäre danach wieder CO<sub>2</sub> zu entziehen, sei der weltweite Ersatz von Zement durch Holz beim Bauen, den er als Direktor des IIASA vor allem erforschen wolle. Die Wahrscheinlichkeit dafür, dass „noch alles gutgehen" werde, sei gering. https://www.derstandard.at/story/3000000204635/klimaforscher-schellnhuber-werden-auch-ueber-das-zwei-grad-ziel-hinausschiessen

    1. “A second Trump term is game over for the climate — really!”

      adjacency - between - Michael Mann - 2nd Trump presidency - exceeding planetary boundaries - exceeding 1.5 Deg C - Trump's presidency is existential threat to humanity - Gen Z voting - 2024 election - adjacency statement - Michael Mann's quote " A second Trump term is game over for the climate - really" applies to the 2024 election if Trump becomes the Republican nominee. - Trumps dismal environmental record in his 2016 to 2020 term speaks for itself. He would do something similiar in 2025 if he were the president. G - Given there are only 5 years and 172 days before we hit the dangerous threshold of burning through all the carbon budget for humanity, - https://climateclock.world/ - It is questionable whether Biden's government alone can do enough, but certainly if Trump won the 2024 election, his term in office would create a regression severe enough to put the Paris Climate goal of staying within 1.5 Deg C out of reach, and risk triggering major planetary tipping points - A Biden government is evidence-based and believes in anthropogenic climate change and is already taking measures to mitigate it. A Trump government is not evidence-based and is supported by incumbent fossil fuel industry so does not have the interest of the U.S. population nor all of humanity at heart. - Hence, the 2024 U.S. election can really determine the fate of humanity. - Gen Z can play a critical role for humanity by voting against a government that would, in leading climate scientists Michael Mann's words, be game over for a stable climate, and therefore put humanity and unimaginable risk. - Gen Z can swing the vote to a government willing to deal with the climate crisis over one in climate denial so voting activists need to be alerted to this and create the right messaging to reach Gen Z - https://hyp.is/LOud7sBBEe6S0D8itLHw1A/circle.tufts.edu/latest-research/41-million-members-gen-z-will-be-eligible-vote-2024

    1. now we are facing a high risk of overshooting 1.5°C - at best - for several decades. Currently, we must admit that we do not know what the consequences are of such an overshoot, i.e., we do not know how long time the big tipping point systems - like the Gulf Stream or the Coral Reef systems, can cope with high risk temperatures above 1.5°C.

    1. For a flip-of-a-coin chance of staying at or below 1.5°C we have, globally, just five to eight years of current emissions before we blow our carbon budget
      • for: 1.5 Deg C target - 50/50 chance

      • comment

        • What most people don't recognize and pay attention to is 50/50 chance that is part of the 1.5 Deg C target.
        • The world is up in arms about the 1.5 Deg C target when it ONLY GIVES US A 50/50 CHANCE!
        • These are not great odds! In fact, THESE ODDS ARE TERRIBLE! What if you were given those chances in your cancer treatment? You would be concerned, wouldn't you?
        • So what would an intervention closer to 90% chance of staying under 1.5 Deg C look like? If people consider today's intervention impossible, then a 90% chance would be beyond impossible. This is the nature of the challenge we face!

    1. It may be that the climate denialists, even in the 1980s, knew this very well. They denied global heating because they saw it meant social and political change on a scale never seen before. An economic system that had made millions rich and billions at least comfortable would collapse. For those who’ve benefited from the system, death is less frightening than poverty.

    1. In a scenario that hits global net zero emissions by 2050, declines in demand are sufficiently steep that no new long lead-time conventional oil and gas projects are required. Some existing production would even need to be shut in. In 2040, more than 7 million barrels per day of oil production is pushed out of operation before the end of its technical lifetime in a 1.5 °C scenario.

    3. if governments deliver in full on their national energy and climate pledges, then oil and gas demand would be 45% below today's level by 2050 and the temperature rise could be limited to 1.7 °C. If governments successfully pursue a 1.5 °C trajectory, and emissions from the global energy sector reach net zero by mid-century, oil and gas use would fall by 75% to 2050.

    1. It should be noted that the third normative approach considers the global need for electricity asoutlined by the International Energy Agency (IEA) for different scenarios and develops an interim1.5DS within which ICT should not expand its current share of electricity. This electricity budgetuses the IEA trajectories for a 2°C scenario (2DS) and a below 2°C scenario (B2DS) to derive a 1.5°Ctrajectory for world electricity usage through doubling the difference between them and subtractingit from the 2DS as described in [IEA ETP]. This is an interim approach as IEA has not yet establisheda 1.5DS. The budget is then used to determine the amount of electricity that could be used by thesector if keeping its share at the current level. As the IEA is planning to include a specific 1.5DS, thetrajectories will be reviewed when the new IEA scenarios are published.

      This is the only mention of a "fair share" of global electricity use by the ICT sector

    1. The remaining global carbon budget for a 50% chance of holding the 1.5°C line is down to crumbs, adding up to a meagre 250 billion tons of carbon dioxide, equivalent to 6-7 years of global emissions at the current pace. This gives us no choice, but to have all countries, businesses, citizens across the entire world working collectively and unified to solve the planetary crisis.

      • comment
        • In Johan’s interview with Kevin Anderson, he articulates that when we account for:
          • the conservative nature of IPCC, which means it doesn’t account for much outlier, cutting edges research and is already outdated ( ie doesn’t contain tipping point elements, latest research in Antarctica and Greenland (Jason Box)
          • only a 50% chance
          • low likelihood of scaling NET in a meaningful way
          • when just is added to safe boundaries, 1 deg C is the real threshold
        • it already implies that we have at small chance of staying under 1.5 deg C

        • the implications are that the carbon budget is even smaller than the current number.
        • the implications are that 1.5 Deg C is not the threshold we should be aiming for, but even less. We are now at 1.2 so it has to be 1.3 or 1.4.
      • question

        • Given the underestimates, should the target actually be revised downwards to 1.3 or 1.4 deg C?

    1. Der Brite Jim Skea wurde zum neuen Vorsitzenden des IPCC gewählt. In einem Spiegel-Interview wiederholte er das Statement, dass das Überschreiten des 1,5°-Ziels nicht das Ende der Menschheit bedeute. Skea bezog sich auf die Aussage des IPCC, dass das 1,5° Ziel nur nach einem zeitweisen Überschreiten durch Entfernung von CO<sub>2</sub> aus der Atmosphäre erreicht werden kann.

    1. In this first part of a two-part article on the relevance of 1.5°C, we unpick the policy gulf that exists between the Paris Agreement climate goals and our real-world emissions trajectory. Part two, forthcoming, will ask whether it is still tenable to claim that 1.5°C is in any meaningful sense ‘alive’.

      Part One of two-part article - on the relevance of 1.5°C, - unpack the policy gulf that exists between - the Paris Agreement climate goals and - real-world emissions trajectory. - Part one challenges - the techno-optimistic position, - embodied by international leaders and the COP process - as being wilfully ignorant of reality.

      Part two, forthcoming - question - is still tenable to claim that 1.5°C is in any meaningful sense ‘alive’. - Question recent suggestions that, - because a 50% chance has all but slipped beyond reach, - 1.5°C is now effectively dead in the water. - Exploration of the dangers of disregarding societal transformations - that could yet deliver an outside chance of 1.5°C.

      • Title: Faster than expected
      • subtitle: why most climate scientists can’t tell the truth (in public) Author: Jackson Damien

      • This is a good article written from a psychotherapist's perspective,

      • examining the psychology behind why published, mainstream, peer reviewed climate change research is always dangerously lagging behind current research,
      • and recommending what interventions could be be taken to remedy this
      • This your of scientific misinformation coming from scientists themselves
      • gives minimizers and denialists the very ammunition they need to legitimise delay of the urgently needed system change.
      • What climate scientists say In public is far from what they believe in private.
      • For instance, many climate scientists don't believe 1.5 Deg. C target is plausible anymore, but don't say so in public.
      • That reticence is due to fear of violating accepted scientific social norms,
      • being labeled alarmist and risk losing their job.
      • That creates a collective cognitive dissonance that acts as a feedback signal
      • for society to implement change at a dangerously slow pace
      • and to not spend the necessary resources to prepare for the harm already baked in.
      • The result of this choice dissonance is that
      • there is no collective sense of an emergency or a global wartime mobilisation scale of collective behaviour.
      • Our actions are not commensurate to the permanent emergency state we are now in.
      • The appropriate response that is suggested is for the entire climate science community to form a coalition that creates a new kind of peer reviewed publishing and reporting
      • that publicly responds to the current and live knowledge that is being discovered every day.
      • This is done from a planetary and permanent emergency perspective in order to eliminate the dangerous delays that create the wrong human collective behavioural responses.
      • The author suggests 5 different steps that will enable and empower scientists to tell the truth at scale:
          1. Admit that rigid adherence to their academic methods, in this astonishingly rapid context, leads directly to their failure to communicate the truth. For one thing, it is widely held on the scientific community that staying under 1.5 Deg. C is no longer plausible.
          1. Form a unified global coalition. Work with communications and psychology experts to present as accurate and as current information as possible
          1. Coalition takes actions to announce a permcrisis requiring responding to new live information in real time, bot wait every 7 years for the next IPCC report
    1. The long-term consequences of Russia’s war are less clear. But experts are concerned it may also lock in more future fossil fuel dependence as places like Europe search for replacements for Russian fuel.
      • Russian war may increase usage of fuels
      • this could make reaching the 1.5 Deg C target more difficult
    2. Most of them are, in general, moving in the right direction. They just aren’t aggressive enough yet to be consistent with the kind of transformative social change required to achieve the 1.5 C target.
      • climate change actions
      • Most of the climate actions are moving in the right direction.
      • but they just aren’t aggressive enough yet to achieve the 1.5 C target.
      • right direction, wrong speed
    1. We conclude that meeting the1.5°C goal is not plausible, although it is not impos-sible. The future scope and pace of social transfor-mations toward climate action would be crucial forattaining the Paris Agreement temperature goals
      • meeting 1.5 Deg C goal is not plausible.
      • future scope and pace of social transformation towards climate action is crucial to meet the target

    1. 1.5 degrees Celsius is the safe boundary this aligns with the intergovernmental panel on climate change with one difference we emphasize that this is a physical limit push it beyond that point 00:05:23 and we risk permanent damage on societies and the world economy

      !- first boundary : 1.5 deg C is a physical boundary - we cannot it it we want to retain a planet safe for human civilization - “ If the world breaches 1.5C, we are likely to trigger at least five tipping points, including the irreversible melting of the Greenland ice sheet and loss of the world’s tropical coral reef systems. This will be devastating for future generations. It will literally change the world, and yet every month we use 1% of the remaining carbon budget for 1.5ºC.” From earth commission website: https://earthcommission.org/news/earth-commission-news/pioneering-science-reveals-set-of-earth-system-boundaries-that-can-secure-a-safe-and-just-planet-for-all/

    1. so let's take the headline budgets and let's adjust them to today November 00:13:16 2022. so these are the the two probabilities that we're using um that's the budget that we have left for two degrees Centigrade that's the budget we've got for 1.5 and these are the years you have 00:13:29 so you know 1.5 nine and a half years of current emissions if the current emissions stayed static we'd have nine and a half years oh a bit worrying um that's about half a percent a bit 00:13:43 under half a percent every month for two degrees centigrade and one percent so every month we're using one percent of the 50 50 chance of 1.5 degrees Centigrade which is not anyway a safe 00:13:54 threshold every month one percent of the budget

      !- key takeaway : time remaining to decarbonize to 1.5 Deg C limit - 9.5 years remaining referenced to Nov 2022 - consuming roughly 1% of remaining 380 Gigaton budget every month, or about 11 % every year.

    1. So what can we make of politicians who continue to argue that ‘1.5°C is still alive’? Are they misinformed or are they simply lying?I believe many are in denial about the types of solutions the climate crisis demands. Rather than do the – admittedly – very difficult political work of eking out our supplies of fossil fuels while accelerating a just transition to post-carbon societies, politicians are going all out on technological salvation. This is a new form of climate denial, which involves imagining large-scale carbon dioxide removal that will clean up the carbon pollution that we continue to pump into the atmosphere. While it may seem much safer to stick to the script and say that it is still physically possible to limit warming to no more than 1.5°C, while pointing out that the scale of change demands much more political will, I believe that this can no longer be a credible response to the climate crisis.We have warmed the climate by 1.2°C since pre-industrial periods. If emissions stay flat at current levels, then in around nine years the carbon budget for 1.5°C will be exhausted. And, of course, emissions are not flat – they are surging. 2021 saw the second-largest annual increase ever recorded, driven by the rebound in economic activity after Coronavirus lockdowns. We did not ‘build back better’.The clock has been stuck at five minutes to midnight for decades. Alarms have been continuing to sound. There are only so many times you can hit the snooze button.

      Going all out on technological salvation is a form of climate denialism.

      We are at 1.2 Deg C and emissions have climbed after rebounding after Covid. If they flatline for the next nine years, we will hit 1.5 Deg C.

    1. Drei führenden Klimawissenschaftler *kritisieren die Illusion der "Net Zero-Politiken", die darauf setzen, das 1,5°-Ziel durch die Entfernung von CO2" aus der Atmosphäre zu erreichen. Sie werfen vielen ihrher KollegInnen vor, unrealistischen Konzepten nicht offen entgegenzutreten, um ihren politischen Einfluss nicht zu verlieren. Sie kritisieren auch die bisherigen Integrated Assessment Models des Weltklimarats, die von der Voraussetzung ausgehen würde, die Klimakatastrophe ließe sich mit marktwirtschaftlichen Mitteln beheben und fordern auf, deutlich zu sagen, dass sich eine Erhitzung der Erde auf 3 und mehr Grad nicht durch kleine Schritte, sondern nur durch einen Bruch mit dem bisherigen Wirtschaftssystem erreichen läßt.

      Anstatt uns unseren Zweifeln zu stellen, beschlossen wir Wissenschaftler, immer aufwändigere Fantasiewelten zu konstruieren, in denen wir sicher wären. Der Preis, den wir für unsere Feigheit zahlen mussten: Wir mussten den Mund halten über die immer größer werdende Absurdität der geforderten Kohlendioxid-Entfernung im planetarischen Maßstab.
