Liegt das auch an externen Faktoren? Ein Bericht des Stockholm International Peace Research Institute (Sipri) hat nun untersucht, welche Rolle der Klimawandel bei diesem Konflikt spielt und welche Auswirkungen er auf die Friedensbemühungen der Uno in Mali hat.

New research shows that lake "stratification periods" – a seasonal separation of water into layers – will last longer in a warmer climate. These longer periods of stratification could have "far-reaching implications" for lake ecosystems, the paper says, and can drive toxic algal blooms, fish die-offs and increased methane emissions.

There was a “relentless” intensification of the climate crisis in 2020, according to the UN’s World Meteorological Organization.

Auf der Erde ist es 1,2 Grad wärmer als noch im vorindustriellen Zeitalter. Vor allem die Konzentration der Klimakiller Lachgas und Methan hat dramatisch zugenommen.

Katherine Tai, the United States trade representative, made a case on Thursday for using trade policies to fight climate change, devoting her first speech in her new position to addressing one of President Biden’s top priorities.

The Climate Council’s new report, released today, shows the immense cost of this inaction. It is now virtually certain Earth will pass the critical 1.5℃ temperature rise this century – most likely in the 2030s.

Given the circumstances, Scientific American has agreed with major news outlets worldwide to start using the term “climate emergency” in its coverage of climate change

What we were doing, and what anthropology was doing, essentially, since the late 19th century, was sort of salvaging work, salvaging the cultures that were disappearing.

"Weltweit steigt mit dem Klimawandel das Risiko von extremen Regenfällen und Überschwemmungen", fasst Will Steffen von der australischen Nationaluniversität zusammen. Der Professor ist einer der führenden Klimatologen Australiens. "Die globale Durchschnittstemperatur ist bereits um etwa 1,1 Grad Celsius gestiegen. Für jeden Temperaturanstieg von einem Grad kann die Atmosphäre etwa sieben Prozent mehr Wasser aufnehmen", so Steffen

Affinity groups, as they’re often called within the study of social movements, have been a common feature of grassroots political organising in recent years. “We have seen this developing over time, in many contemporary movements – where people are valued for their expertise and what they can bring within the larger movement,” says Bart Cammaerts, a professor of politics and communication at the London School of Economics.

For XR itself, the model seems to have worked, if anything from a numerical standpoint. As academics Douglas McAdams and Ronnelle Paulsenfound in 1993, knowing someone who is involved in social movements is one of the strongest predictors of recruitment into that same movement.

Clearly, the economic contributions of biodiversity are highly significant as reflected in the many efforts to expose and capture economic values of biodiversity and ecosystem services

The ocean contains unique biodiversity, provides valuable food resources and is a major sink for anthropogenic carbon. Marine protected areas (MPAs) are an effective tool for restoring ocean biodiversity and ecosystem services1,2, but at present only 2.7% of the ocean is highly protected3. This low level of ocean protection is due largely to conflicts with fisheries and other extractive uses.

The rate at which the world’s forests are being destroyed increased sharply last year, with at least 42,000 sq km of tree cover lost in key tropical regions.According to data from the University of Maryland and the online monitoring platform Global Forest Watch, the loss was well above the average for the last 20 years, with 2020 the third worst year for forest destruction since 2002 when comparable monitoring began.

Currently, Pine Island Glacier together with its neighbouring Thwaites glacier are responsible for about 10% of the ongoing increase in global sea level.

Researchers have confirmed for the first time that Pine Island Glacier in West Antarctica could cross tipping points, leading to a rapid and irreversible retreat which would have significant consequences for global sea level.

Despite important agricultural advancements to feed the world in the last 60 years, a Cornell-led study shows that global farming productivity is 21% lower than it could have been without climate change. This is the equivalent of losing about seven years of farm productivity increases since the 1960s.

In der 30-jährigen Geschichte der Klimapolitik gab es bislang zwei Phasen, in denen das Thema dominiert hat. Beide wurden von einer noch akuteren Krise jäh beendet.

Earth's ice imbalance

ice mass change between 1994 and 2017 part

Since 2012, the rate of ice loss from Antarctica has tripled when compared to the previous two decades, owing to widespread glacier speed-up (Mouginot et al., 2014) and thinning (Shepherd et al., 2019) in the Amundsen and Bellingshausen Sea sectors in response to the circulation of warm water under the region's ice shelves (Jacobs et al., 2011).

Yet after the $1.9tn coronavirus relief package, deficit angst is back in some circles, and the upcoming infrastructure and climate bill could cost another $2tn. President Joe Biden proposed a raft of new tax increases during his campaign that will be fiercely opposed by Republicans and business groups. In this showdown, climate investments should be prioritised — even if they are deficit financed.

It’s the first time in the award’s 46-year history that retrofitting, the practice of upgrading buildings rather than knocking them down to start again, has triumphed. Lacaton & Vassal’s victory has shaken up the architectural profession and signals a remarkable shift in priorities among the world’s best city-makers. If embraced more widely, this could transform how buildings everywhere are regenerated.

The study, published in Nature Food, presents EDGAR-FOOD – the first database to break down emissions from each stage of the food chain for every year from 1990 to 2015. The database also unpacks emissions by sector, greenhouse gas and country. 

Or il y a forcément des gens qui vont s’opposer aux réformes nécessaires pour faire la transition écolo. Beaucoup de jeunes des mouvements climat, que j’admire, pensent que c’est une question de bon sens. Malheureusement non, c’est un combat dans lequel il y a un adversaire.

17,6% des espèces évaluées sont menacées en France, d’après la liste rouge élaborée par l’Union internationale pour la conservation de la nature (UICN),

„Die Meinung einer Minderheit kann in der Öffentlichkeit als Mehrheit erscheinen, wenn ihre Anhänger nur selbstbewusst genug auftreten und ihre Meinung öffentlich mit Nachdruck vertreten.“

In this pivotal year for climate action, much will depend on the updated 2030 emissions-reduction target that the US sets for itself. To meet the challenge at hand, the new target will need to be even more ambitious than the 50% reduction in greenhouse-gas emissions (from 2005 levels) that is currently being floated in Washington.

Wien/Schwechat – Die Lufthansa-Tochter AUA legt Pressearbeit und Lobbying zusammen. Leiten wird diesen neuen Bereich namens "Corporate Communications, Public Affairs & Corporate Responsibility" ab April die bisherige Leiterin der ÖAMTC-Öffentlichkeitsarbeit, Sophie Matkovits, wie die Fluggesellschaft am Mittwoch mitteilte.

More recently, from 2009 to 2014, Hastrup ran Waterworlds, a major European research project analysing social responses to climate change,[5] followed by fieldwork in Greenland, where she researched the effects of the modern world on a small community of hunters.[6]

Die Dokumentation erhielt die Auszeichnung als „Bester Wissenschaftsfilm“ beim Internationalen Green Screen Naturfilmfestival in Eckernförde 2020. Die Einschätzung der internationalen Jury des Green Screen Festivals in der Laudatio zum Film: „Er zeigt anhand anschaulicher Einzelschicksale und verstörender Bilder die Auswirkungen des Klimawandels auf Rentierhirten und die Natur Sibiriens, ohne den globalen Bezug aus den Augen zu verlieren." Außerdem gewann der Film 2020 beim „Jackson Wild Festival“ in der Kategorie „Best Changing Planet Film - Long Form“.

Il s’agit en fait plu­tôt d’une inca­pa­ci­té de pen­ser vrai­ment avec cette pos­si­bi­li­té que quelque chose vienne enrayer la nor­ma­li­té des choses, la rou­tine de la crois­sance…

The purpose of this blog is to exegete and test the political theology of Bruno Latour, including his concept of ‘religion as a mode of existence’ as developed in his Inquiry into Modes of Existence and elsewhere. As well as his own texts, the blog will attempt to bring to bear interlocutors to Latour’s political theology, both acknowledged and unacknowledged, including Michel Serres, Peter Sloterdijk, Jan Assmann, Carl Schmitt, Rowan Williams and Michael Northcott.

For Latour, the ideology of neoliberalism has caused the operation of global capital to be elevated to the same order as that of inert matter: both are taken as fixed and obligatory realities that are entirely independent of the contingent behaviour of human beings in the world down-below.

best-available evidence—ie, in formal evidence synthesis.

The courses span a suite of synthesis methods, including systematic review and systematic mapping, stakeholder engagement in evidence synthesis, and evidence synthesis technology.

Because there is no time left for trial and error and since resources for organising a transformation into a carbon‐neutral world are inherently limited, decision‐making on climate solutions needs to be based on the best available evidence.

Evidence synthesis, which collates, appraises, and summarises results from individual studies across an evidence base and makes them available for policy advice, is particularly well organised in the health sciences; a key role is played here by the global knowledge network Cochrane, founded in 1993 and seated in London. T

The evolution of Holocene temperature reconstructed by the five methods are generally similar, although the amplitude of change is higher for CPS. The multi-method median reconstruction is very similar to the only other available multi-proxy, Holocene GMST reconstruction2 (Fig. 6). Our reconstruction, which is based on much more proxy data and multiple statistical methods, reinforces the mismatch between higher-than-pre-industrial GMST as represented by the proxy data versus the lower-than-pre-industrial GMST as simulated by climate models3. Understanding what caused this mismatch will undoubtedly be the focus of subsequent studies.

An extensive new multi-proxy database of paleo-temperature time series (Temperature 12k) enables a more robust analysis of global mean surface temperature (GMST) and associated uncertainties than was previously available. We applied five different statistical methods to reconstruct the GMST of the past 12,000 years (Holocene).

Ich halte es aus drei Gründen für praktisch sicher, dass es eine so rasche Erwärmung noch nicht gab:

Eine Forschergruppe von den Harvard und Oregon State Universitäten hat in Science die erste globale Temperaturrekonstruktion für die vergangenen 11,000 Jahre publiziert – das ganze Holozän. Die Ergebnisse besprechen wir hier in Teil 3 unserer kleinen Paläoklima-Serie.

Der bekannte Übergang vom relativ warmen Mittelalter in die „kleine Eiszeit“ erweist sich als Teil einer viel langfristigeren Abkühlung, die mit der rasanten Erwärmung im 20. Jahrhundert ein jähes Ende gefunden hat.

Mr. Biden also on Wednesday issued a sweeping presidential memorandum instructing agencies to make what the White House called “evidence-based decisions guided by the best available science and data.” Every agency, not just those that do scientific research, must appoint “scientific integrity” officials.

Die Arbeit von zwei US-Mikrobiologen könnte helfen, Antibiotika zu vermeiden. Denn sie haben entdeckt, wie Bakterien miteinander kommunizieren. Dafür erhalten sie den Paul-Ehrlich- und Ludwig-Darmstaedter-Preis.

But if the breakdown of our civilization was timed by the failure of world economy, it was certainly not caused by it. Its origins lay more than a hundred years back in that social and technological up- heaval from which the idea of a self-regulating market sprang in Western Europe. The end of this venture has come in our time ; it closes a distinct stage in the history of industrial civilization.

Hulme and colleagues set out to reveal patterns of attention and, in particular, patterns of framing6 with regards to how climate change is portrayed in these editorials, and how these patterns are related to wider political and scientific events. The authors identified frames by reading and discussing nearly 500 editorials on climate change (333 in Nature, 160 in Science) published in the two journals between 1966 and 2016, extracted using search terms such as ‘climate’, ‘greenhouse’, ‘carbon’, ‘warming’, ‘weather’, ‘atmosphere’ and ‘pollution’.

In "Rebellion oder Untergang" rufen Sie zu zivilem Ungehorsam auf. Als Trumps Unterstützer zum Kapitol marschierten, sprachen sie auch von zivilem Ungehorsam ...

In light of that reality, the Times should consider junking its language about journalists being “perceived as biased.” Thanks to the work of unprincipled folks in American politics, the mere expression of an opinion, or an emotion, is now viewed as evidence of ingrained bias. Opinion and bias are not the same.

Für die Klimakommunikation aber ist es jetzt Zeit für eine Schwerpunktverschiebung: weg von der Frage der Generierung von Aufmerksamkeit, Interesse und Verständnis für das existenzielle Thema und hin zur Kommunikation von Lösungen, zur Beteiligung an Debatten und zur Ermutigung zum Diskurs, zum Engagement – und zum Wandel.

The small size of the remaining carbon budget emphasises the need for net-zero CO2 emissions targets at the international, national and even subnational level. 

The relationship between cumulative CO2 emissions and temperature change is known as the “Transient Climate Response to Cumulative Emissions” (TCRE) and is a robust predictor of CO2-induced warming across a wide range of emissions levels and pathways.

In the context of net-zero targets, our 230-440bn tonne range would be consistent with a scenario where CO2 emissions decrease linearly from 2019 levels to net-zero by between 2032 and 2042.

this design should be regenerative

“Bullets are for killing. I’m more interested in a golden seed. What do we need to plant so we can make the design of our institutions, financial systems, and economic framework regenerative and distributive?”

Kerry, the former US secretary of state, acknowledged that America had been absent from the international effort to contain dangerous global heating during Donald Trump’s presidency but added that “today no country and no continent is getting the job done”.

Alle an Klimakommunikation beteiligten Akteure können einen Beitrag leisten, die Debatte immer wieder auf den entscheidenden Punkt zu bringen: Was können wir und insbesondere diejenigen, die in Wirtschaft und Politik Verantwortung tragen, hier und jetzt tun, um die Emissionen von Kohlendioxid und anderen Treibhausgasen einzugrenzen? Die folgenden sechs Empfehlungen sind nicht als Allheilmittel oder Universalrezept gemeint, sondern als Anregung, darüber nachzudenken, wie wir über das Thema Klimawandel kommunizieren. Das zentrale Kriterium effektiver Kommunikation müsste dabei die Frage sein: Bringt das, was wir zum Thema sagen, die Menschen dazu, hier und jetzt über Klimaschutz nachzudenken?

Over the last decade, degrowth has offered a concrete alternative to eco-modernization, projecting a society emancipated from the environmentally destructive imperative of competition and consumption. Urban development is the motor of economic growth; cities are therefore prime sites of intervention for degrowth activists. Nevertheless, the planning processes that drive urban development have yet to be questioned from a degrowth perspective.

Even before Mr. Biden was inaugurated on Wednesday, some Republicans lashed out against his new policy direction.

Yesterday was the day that NASA, NOAA, the Hadley Centre and Berkeley Earth delivered their final assessments for temperatures in Dec 2020, and thus their annual summaries. The headline results have received a fair bit of attention in the media (NYT, WaPo, BBC, The Guardian etc.) and the conclusion that 2020 was pretty much tied with 2016 for the warmest year in the instrumental record is robust.

Scientists at Lawrence Livermore National Laboratory in collaboration with colleagues from Nanjing University and Texas A&M University have re-evaluated how much future global warming is in the pipeline if atmospheric greenhouse gas concentrations were to remain fixed at present-day levels, a quantity known as committed warming. Their new analysis accounts for the fact that surface warming to date has been large in certain regions but small in others, which has temporarily allowed Earth to shed heat more efficiently. Ignoring this “pattern effect”, as has been done in previous studies, gives the false impression that Earth’s energy budget is nearly balanced and implies that committed warming is only about 1.3°C (2.3°F) above pre-industrial levels. The team’s updated estimate is substantially larger, with a most likely value of 2.3°C (4.1°F). 

Our planet’s energy balance is sensitive to spatial inhomogeneities in sea surface temperature and sea ice changes, but this is typically ignored in climate projections. Here, we show the energy budget during recent decades can be closed by combining changes in effective radiative forcing, linear radiative damping and this pattern effect. The pattern effect is of comparable magnitude but opposite sign to Earth’s net energy imbalance in the 2000s, indicating its importance when predicting the future climate on the basis of observations. After the pattern effect is accounted for, the best-estimate value of committed global warming at present-day forcing rises from 1.31 K (0.99–2.33 K, 5th–95th percentile) to over 2 K, and committed warming in 2100 with constant long-lived forcing increases from 1.32 K (0.94–2.03 K) to over 1.5 K, although the magnitude is sensitive to sea surface temperature dataset. Further constraints on the pattern effect are needed to reduce climate projection uncertainty.

The widespread idea that decades, or even centuries, of additional warming are already baked into the system, as suggested by previous IPCC reports, were based on an “unfortunate misunderstanding of experiments done with climate models that never assumed zero emissions.”
