Trans Mountain said there have not been any oil leaks due to the flooding, which has triggered an emergency shutdown of the pipeline lasting longer than any previous stoppage in its nearly 70-year-history.

The climate catastrophe we're facing is the result of three issues, three processes.

we believe that knowledge must be shared in order for humanity to survive and thrive—and that it is essential to help fight climate change.

The open movement must develop a clear and deep relationship of collaboration with the climate movement, most importantly because the latter is the locus of political renewal and connection of an intersectional approach to action and change.

What resources are powering our projects and how do we manage those resources? Are we willing to approach our work with a set of values that centers several generations after us? And how do we do that?What protections do we need to fight for in the workplace to hold companies accountable around climate justice goals?How do we measure our impact on the climate crisis?Are we willing to sundown projects if mitigating their negative impact on the environment is impossible or creates little impact?

Poultry scientists have also succeeded in selecting for parthenogenesis, increasing the incidence in Beltsville small white turkeys more than threefold, to 41.5 percent in five generations. Environmental factors—like high temperatures or a viral infection—also seem to trigger poultry parthenogenesis.

Lowering these risks and adapting to those we can no longer avoid will require a mobilisation of resources on the scale of a war economy.

e.g. Idea from Yuval Harari’s Sapiens that Europe and Asia developed better civilisation than Americas because Americas span vertically lot of climates making it harder to share agriculture progress between different climates.

there’s a group of us who are figuring out what this Centre for Climate Justice is going to be and what its scope is going to be.

A recent survey found that only 14% of people they surveyed in the United States talk about climate change. A previous Yale study found that 35% either discuss it occasionally or hear somebody else talk about it. Those are low for something that over 70% of people are worried about.

For a talk at one conservative Christian college, Dr. Hayhoe – an atmospheric scientist, professor of political science at Texas Tech University, and the chief scientist for The Nature Conservancy – decided to emphasize how caring about climate change is in line with Christian values and, ultimately, is “pro-life” in the fullest sense of that word. Afterward, she says, people “were able to listen, acknowledge it, and think about approaching [climate change] a little differently.”

I was speaking in Iowa, and I was asked, “How do you talk to people in Iowa about polar bears?” I said, “You don’t; you talk to them about corn.” If we begin a conversation with someone with something we already agree on, then the subtext is: “You care about this, and I care too. We have this in common.”

I am frequently shamed for not doing enough. Some of that comes from the right side of the [political] spectrum, but increasingly a larger share of that shaming comes from people at the opposite end of the spectrum, who are so worried and anxious about climate impacts that their response is to find anyone who isn’t doing precisely what they think they should be doing and shame them.

When we practice active hope, when we look at what people are doing, and we share those stories with others and talk about what we can do together, then we realize that the boulder is already at the top of the hill and is rolling down in the right direction, and has millions of hands on it. It’s just not going fast enough.

Fundamental features of human psychology can constrain the perceived personal relevance andimportance of climate change, limiting both action and internalization of the problem. Cognitiveshortcuts developed over millennia make us ill-suited in many ways to perceiving and respondingto climate change (152),including a tendency to place less emphasis on time-delayed and physicallyremote risks and to selectively downplay information that is at odds with our identity or worldview(153). Risk perception relies on intuition and direct perceptual signals (e.g., an immediate, tangiblethreat), whereas for most high-emitting households in the Global North, climate change does notpresent itself in these terms, except in the case of local experiences of extreme weather events.

The fossil fuel industry helped to create the PR industry, and publicists came up with disinformation and manipulation tactics that they deployed for oil, tobacco, and chemical companies for decades.

The climate of Japan is predominantly temperate but varies greatly from north to south. The northernmost region, Hokkaido, has a humid continental climate with long, cold winters and very warm to cool summers. Precipitation is not heavy, but the islands usually develop deep snowbanks in the winter.[85]

Global air traffic is expected to double to 8.2 billion passengers in 2037, according to IATA, which predicts that aviation's 2019 emissions peak of around 900 million metric tons of CO2 will be exceeded within the next two to three years.At the same time, the window to cut the world's reliance on fossil fuels and avoid catastrophic changes to the climate is closing rapidly. The International Energy Agency forecasts that aviation's share of global carbon emissions will increase to 3.5% by 2030 from just over 2.5% in 2019 in the absence of efforts to further decarbonize.

Since about 70% of water delivered from the Colorado River goes to growing crops, not to people in cities, the next step will likely be to demand large-scale reductions for farmers and ranchers across millions of acres of land, forcing wrenching choices about which crops to grow and for whom — an omen that many of America’s food-generating regions might ultimately have to shift someplace else as the climate warms.

The tunnel far below represented Nevada’s latest salvo in a simmering water war: the construction of a $1.4 billion drainage hole to ensure that if the lake ever ran dry, Las Vegas could get the very last drop

No one but Humboldt had looked at the relationship between humankind and nature like this before.

Limiting warming to 1.5°C implies reaching net zero CO2 emissions globally around 2050 and concurrent deep reductions in emissions of non-CO2 forcers, particularly methane (high confidence). Such mitigation pathways are characterized by energy-demand reductions, decarbonization of electricity and other fuels, electrification of energy end use, deep reductions in agricultural emissions, and some form of CDR with carbon storage on land or sequestration in geological reservoirs.

Pathways that aim for limiting warming to 1.5°C by 2100 after a temporary temperature overshoot rely on large-scale deployment of carbon dioxide removal (CDR) measures, which are uncertain and entail clear risks.

Limiting warming to 1.5°C depends on greenhouse gas (GHG) emissions over the next decades, where lower GHG emissions in 2030 lead to a higher chance of keeping peak warming to 1.5°C (high confidence). Available pathways that aim for no or limited (less than 0.1°C) overshoot of 1.5°C keep GHG emissions in 2030 to 25–30 GtCO2e yr−1 in 2030 (interquartile range). This contrasts with median estimates for current unconditional NDCs of 52–58 GtCO2e yr−1 in 2030.

Ultimately, having access to the top political decision makers and using biased studies, the industrial lobbies have managed to sabotage the reforms the Convention Citoyenne pour le Climat called for. A context and tactic we are only too familiar with.

the climate movement is also structurally vulnerable to doomist intellectuals who claim that science supports their ideas.

71% of global emissions can be traced back to 100 companies,

C.1.3. Limiting global warming requires limiting the total cumulative global anthropogenic emissions of CO2 since the pre-industrial period, that is, staying within a total carbon budget (high confidence).1414By the end of 2017, anthropogenic CO2 emissions since the pre-industrial period are estimated to have reduced the total carbon budget for 1.5°C by approximately 2200 ± 320 GtCO2 (medium confidence). The associated remaining budget is being depleted by current emissions of 42 ± 3 GtCO2 per year (high confidence).

Right now, most of the blockchain mining in the world happens in China, where provinces with the cheapest energy set up mining operations to do the ‘proof of work’ calculations that the dominant paradigm of blockchain requires. Factories that ostensibly make other things now acquire significant computing hardware and dedicate energy in order to, essentially, print money that’s then stored offshore. A recent study shows that 40% of China’s mostly bitcoin mining is powered by coal-burning. We also already know that non-blockchain server farms in cheap energy countries consume so much energy they distort national grids, and throw off huge amounts of heat that then need cooling for the servers to operate, creating a vicious cycle of energy consumption

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

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.

The owners of coal-burning power stations in the UK have not obtained the consent of everyone who owns a lake or a forest in Sweden to deposit acid rain there.

a simple and coherent explanation of why libertarianism is so often associated with climate change denial, and the playing down or dismissal of other environmental issues.

Manmade CO2 Does Not Cause Measurable Warming

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. 

„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.

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]

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’.

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. 

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?

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.

People thrive in a wide range of climates. The projected climate change is small relative to the diurnal cycle. It is therefore rather peculiar to conclude that climate change will be disastrous. Those who claim so have been unable to explain why. https://twitter.com/RichardTol/status/1313182006310731776?s=20

These predictions are absurd. A 3°C increase could trigger, and a6°C increase would trigger, every “tipping element” shown in Table 2. The Earth would have a climate unlike anything our species has experienced in its existence, and the Earth would transition to it hundreds of times faster than it has in any previous naturally-driven global warming event (McNeall et al., 2011). The Tropics and much of the globe’s temperate zone would be uninhabitable by humans and most other life forms. And yet Nordhaus thinks it would only reduce the global economy by just 8%?Comically, Nordhaus’s damage function is symmetrical — it predicts the same damages from a fall in temperature as for an equivalent rise. It therefore predicts that a 6°C fall in global temperature would also reduce GGP by just 7.9% (see Figure 3). Unlike global warming, we do know what the world was like when the temperature was 6°C below 20th century levels: that was the average temperature of the planet during the last Ice Age (Tierney et al., 2020), which ended about 20,000 years ago. At the time, all of America north of New York, and of Europe north of Berlin, was beneath a kilometre of ice. The thought that a transition to such a climate in just over a century would cause global production to fall by less than 8% is laughable.Again, I found myself in the position of a forensic detective, trying to work out how on Earth could otherwise intelligent people come to believe that climate change would only affect industries that are directly exposed to the weather, and that the correlation between climate today and economic output today across the globe could be used to predict the impact of global warming on the economy? The only explanation that made sense is that these economists were mistaking the weather for the climate.

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.” 

Ein Gastbeitrag von Stefan Rahmstorf Dramatisch übertriebene Berichte über Forschungsergebnisse können Resignation auslösen. Ein aktuelles Beispiel machte wieder Schlagzeilen – dabei war die Methode wenig aussagekräftig.

The Zero Emissions Commitment (ZEC) is the change in global mean temperature expected to occur following the cessation of net CO2 emissions and as such is a critical parameter for calculating the remaining carbon budget. The Zero Emissions Commitment Model Intercomparison Project (ZECMIP) was established to gain a better understanding of the potential magnitude and sign of ZEC, in addition to the processes that underlie this metric. A total of 18 Earth system models of both full and intermediate complexity participated in ZECMIP. All models conducted an experiment where atmospheric CO2 concentration increases exponent
