"In vielen Alpenregionen hat sich die Anzahl der Blitze in den letzten 40 Jahren durch den Klimawandel verdoppelt. Die erhebliche Bedrohung für Menschen, Tiere und technologische Einrichtungen sind damit stark gestiegen."

Forschung und Wissen · Klimawandel hat Blitze in den Alpen verdoppeltBy Robert Klatt

Very weird move to make at this moment. #IPCC participation is ‘cheap’ (because authors are currently not paid directly), so for very few travel $$ the #Canada gov't can claim a large impact on & leadership in global #ClimateChange assessment.

“Canada will no longer cover travel costs of experts it nominates to UN's climate science body / Funding cut leaves scientists wondering if they can be part of key global climate assessment”

CBCCanada will no longer cover travel costs of experts it nominates to UN's climate science body | CBC NewsIn a sudden and unexplained change from previous decades, the federal government has stopped covering the travel costs of Canadian experts volunteering for the next major global climate science assessment.

🧵 5/6 - using #ClimateKG the #IPCC reports can have search and logical reasoning, for example if the following question was asked: ‘How to design a city climate action plan to mitigate against extreme weather such as floods and fires — what are the mitigation policy options — and where are the authoring scientists geographically based?’.

Capitalism Eating Itself by Fueling Climate Mayhem, Warns Capitalist

If humanity stays on current course, warns top insurer, the "financial sector as we know it ceases to function. And with it, capitalism as we know it ceases to be viable."

According to GüntherThallinger, a former top executive at Germany's branch of the consulting giant #McKinsey & Company and currently a board member of #Allianz SE, one of the largest insurance companies in the world, the #ClimateCrisis is on a path to destroy #capitalism as we know it.

"We are fast approaching temperature levels—1.5C, 2C, 3C—where #insurers will no longer be able to offer coverage for many" of the risks associated with the #climate crisis, Thallinger writes in a recent post highlighted Thursday by #TheGuardian.

There is no way to "adapt" to temperatures beyond human tolerance. There is limited adaptation to #megafires, other than not building near #forests. Whole cities built on flood plains cannot simply pick up and move uphill. And as temperatures continue to rise, adaptation itself becomes economically unviable.

Once we reach 3°C of warming, the situation locks in. Atmospheric energy at this level will persist for 100+ years due to carbon cycle inertia and the absence of scalable industrial carbon removal technologies. There is no known pathway to return to pre-2°C conditions. (See: #IPCC AR6, 2023; NASA Earth Observatory: "The Long-Term Warming Commitment")

At that point, risk cannot be transferred (no insurance), risk cannot be absorbed (no public capacity), and risk cannot be adapted to (physical limits exceeded). That means no more mortgages, no new real estate development, no long-term investment, no financial stability. The financial sector as we know it ceases to function. And with it, capitalism as we know it ceases to be viable.

In 2017 the #IPCC SSP3 emission scenario made a good guess: "A resurgent nationalism, concerns about competitiveness and security, and regional conflicts push countries to increasingly focus on domestic or, at most, regional issues. Policies shift over time to become increasingly oriented toward national and regional security issues. Countries focus on achieving energy and food security goals within their own regions at the expense of broader-based development." #climate

#Degrowth can work — here’s how science can help

Wealthy countries can create prosperity while using less materials and energy if they abandon #EconomicGrowth as an objective.

By Jason Hickel, Giorgos Kallis, Tim Jackson, Daniel W. O’Neill, Juliet B. Schor, Julia K. Steinberger, Peter A. Victor & Diana Ürge-Vorsatz, 12 December 2022

Excerpt: "The global economy is structured around growth — the idea that firms, industries and nations must increase production every year, regardless of whether it is needed. This dynamic is driving climate change and ecological breakdown. High-income economies, and the corporations and wealthy classes that dominate them, are mainly responsible for this problem and consume energy and materials at unsustainable rates.

"Yet many industrialized countries are now struggling to grow their economies, given economic convulsions caused by the COVID-19 pandemic, Russia’s invasion of Ukraine, resource scarcities and stagnating productivity improvements. Governments face a difficult situation. Their attempts to stimulate growth clash with objectives to improve human well-being and reduce environmental damage.

"GDP is getting a makeover — what it means for economies, health and the planet

"Researchers in ecological economics call for a different approach — degrowth. Wealthy economies should abandon growth of gross domestic product (#GDP) as a goal, scale down destructive and unnecessary forms of #production to reduce energy and material use, and focus economic activity around securing human needs and well-being. This approach, which has gained traction in recent years, can enable rapid #decarbonization and stop ecological breakdown while improving social outcomes. It frees up energy and materials for low- and middle-income countries in which growth might still be needed for development. Degrowth is a purposeful strategy to stabilize economies and achieve social and ecological goals, unlike recession, which is chaotic and socially destabilizing and occurs when growth-dependent economies fail to grow.

"Reports this year by the Intergovernmental Panel on Climate Change (#IPCC) and the Intergovernmental Science-Policy Platform on #Biodiversity and #Ecosystem Services (#IPBES) suggest that degrowth policies should be considered in the fight against #ClimateBreakdown and #biodiversity loss, respectively. Policies to support such a strategy include the following.

"Reduce less-necessary production. This means scaling down destructive sectors such as #FossilFuels, mass-produced meat and dairy, #FastFashion, #advertising, #cars and aviation, including #PrivateJets. At the same time, there is a need to end the #PlannedObsolescence of products, lengthen their lifespans and reduce the purchasing power of the #rich.

"Improve #PublicServices. It is necessary to ensure universal access to high-quality #HealthCare, #Education, #Housing, transportation, Internet, #RenewableEnergy and nutritious food. #UniversalPublicServices can deliver strong social outcomes without high levels of resource use.

"Introduce a green jobs guarantee. This would train and mobilize labour around urgent social and ecological objectives, such as installing renewables, insulating buildings, regenerating #ecosystems and improving social care. A programme of this type would end unemployment and ensure a just transition out of jobs for workers in declining industries or 'sunset sectors', such as those contingent on fossil fuels. It could be paired with a #UniversalIncome policy.

"Reduce working time. This could be achieved by lowering the retirement age, encouraging part-time working or adopting a four-day working week [and hybrid or remote work]. These measures would lower #CarbonEmissions and free people to engage in care and other welfare-improving activities. They would also stabilize employment as less-necessary production declines.

"Enable #sustainable development. This requires cancelling unfair and unpayable debts of low- and middle-income countries, curbing unequal exchange in international trade and creating conditions for productive capacity to be reoriented towards achieving social objectives.

"Some countries, regions and cities have already introduced elements of these policies. Many European nations guarantee free health care and education; Vienna and Singapore are renowned for high-quality public housing; and nearly 100 cities worldwide offer free public transport. Job guarantee schemes have been used by many nations in the past, and experiments with basic incomes and shorter working hours are under way in Finland, Sweden and New Zealand.

"But implementing a more comprehensive strategy of degrowth — in a safe and just way — faces five key research challenges, as we outline here."

Der Weltklimarat #IPCC hat der Menschheit den Weg durch die #Klimakrise gewiesen – und befindet sich nun selbst in der Krise. Es geht um den nächsten großen Sachstandsbericht.
Beim letzten IPCC-Treffen wollten vor allem #China, Indien und Saudi-Arabien ganze Themenbereiche streichen lassen – und die Publikation des 7. Berichts weit in die Zukunft verschieben.
Ich habe den Klimaforscher Reto Knutti von der ETH Zürich zu den Vorgängen für „Spektrum“ interviewt: spektrum.de/news/ipcc-bericht- (evtl. €)

Ein dänisches Forscher:innen Team hat aufgrund von Eisbohrkernen aus der Antarktis errechnet, dass für #daenemark der Meeresspiegels nicht statt wie bisher für 2100 vorhergesagt 1m (#ipcc Schätzung) steigen wird, sondern der Anstieg möglicherweise 3m erreichen wird.
Das wäre für viele dänische Städte ein großes Problem, berichtet der Dänische Rundfunk (#dr, #drnyheder):

DR · Danske topforskere frygter havniveaustigninger tre gange højere end ventetDanmarks mest profilerede klimaforskere advarer nu om, at vi risikerer en havniveaustigning på op til tre meter inden 2100.

Der Anstieg des Meeresspiegels muss mehr Beachtung erhalten – das verlangen dänische Klimaforscher:innen.
«Ein Meter in diesem Jahrhundert sagt nicht viel, wenn es anfangs des nächsten Jahrhunderts fünf oder 10 Meter werden. Das ist etwas, das ist spürbar, denn das kann weder Aarhus noch Kopenhagen verkraften.»

Kleine Wahrscheinlichkeit, extrem hohes Risiko – und jetzt?

🎙️ "Ich bin fassungslos, wie die Negierung von Wissen, die #Wissenschaftsfeindlichkeit und Zensur zugenommen haben", sagt #MPIM-Direktor Jochem Marotzke im Interview mit der @maxplanckgesellschaft. 🇺🇸 Er hat selbst in den USA geforscht & teilt seine Einschätzung, was die Maßnahmen der #Trump-Regierung für seine US-Kolleg*innen, die nationale & internationale #Klimaforschung, die Arbeit des Weltklimarates #IPCC & den #Klimaschutz bedeuten.
