The Problem

Physical tipping points amplify warming

“Antarctica is headed for a climate tipping point by 2060, with catastrophic melting if carbon emissions aren’t cut quickly.”

The Conversation, 17mei 2021


“Greenland ice sheet on brink of major tipping point, says study. Scientists say ice equivalent to 1-2 metres of sea level rise is probably already doomed to melt.”

The Guardian, 17 mei 2021

Taking CO2 out of the air cannot prevent Antarctica from melting. Technology that has yet to be invented or won’t be green for another ten to twenty years can’t protect us. By then, the earth will have warmed so much that tipping points in the climate system will amplify the warming by themselves.

It was Professor Hans Joachim Schellnhuber of the Potsdam Institute who first warned of “tipping points” in the Earth’s climate system; tipping points created by climate change, whereby global warming reinforces itself. The best known tipping point is that of the polar caps. If climate change causes the vast white surface of the polar caps to melt, solar rays that are now reflecting back into space will be absorbed into darker seas. This means that the earth is warming faster. This warming is in addition to that of the greenhouse effect that we humans cause and in turn sets in motion new tipping points that cause temperatures to rise even further. When that happens, humans can no longer influence climate change. It will be out of our hands and we will have no choice but to protect society from the damage. This is, in short, the scenario that the Paris Agreement is trying to prevent by limiting the temperature increase to 1.5 degrees Celsius.

The Solution

“The question at a global systems level today is not whether humanity will transition away from fossil fuels. The question is: Will we do it fast enough? Effective planetary stewardship requires updating our Holocene mindset. We must act on the urgency, the scale, and the interconnectivity between us and our home, planet Earth. More than anything, planetary stewardship will be facilitated by enhancing social capital — building trust within societies and between societies.

Social tipping points can turn the tide

The physical tipping points are not to be cheerful about, especially since the first tipping points have already come into effect. But we can still turn the tide, even if the time left to us is getting shorter and shorter. In the coming years, we must reduce more greenhouse gases every year. This is an unprecedented task, especially since greenhouse gases are currently increasing by 0 to 2% per year. But it can be done. And the good news is: it does not require the development of new, expensive technology. Professor Schellnhuber pins his hopes on social tipping points. “The only way to beat the ever-accelerating climate change,” the professor says, “is with ever-accelerating changes in society.” For, like physical tipping points, social phenomena can also trigger a self-reinforcing acceleration. The moment multiple social tipping points start reinforcing each other and lead to structural change, the professor says, we can get ahead of the tipping points in the physical world. It accelerates an equitable transition. / Schellnhuber vanaf ongeveer minuut 6, minuut 17 over Titanic, rond 19 over belang social tipping points / Ilona Otto vanaf ongeveer minuut 51



social tipping point measures

Schellnhauer’s colleague at the Potsdam Institute, Professor Ilona Otto, published in the scientific journal PNAS about social tipping point measures that can accelerate technological developments, greenhouse gas reductions and social acceptance, thereby preventing runaway climate change. She writes explicitly that technological development will probably play an important role, but explicitly not in the sense of technology that has yet to be invented. The key lies more in existing technology that becomes cheaper.

A few examples from the article the undersigned are working for:

1: Divest-invest

Divest and reinvest: shifts in the energy market that make investments in fossil fuel extraction unprofitable and unattractive

Divestment is the social tipping point measure that Otto believes can have the fastest effect, as early as one hour. If pension funds and public and private banks publicly decide to exclude fossil companies from their investment portfolios, new investments become more expensive for the fossil industry and interest in investing in polluting activities decreases. The demand for sustainable investments is also growing. If investors also invest the money in sustainable solutions, this movement will accelerate. DNB argues that the damage caused by climate change should be taken into account in investment policy. The International Energy Agency (IEA) argues that investments in new projects to extract coal, oil and gas must come to an end. In the Netherlands, Greenpeace is increasing the pressure on banks. ABP Fossielvrij and Groen Pensioen are increasing the pressure on Dutch pension funds.

We ask the new cabinet: 

to accelerate the social tipping point by obliging public and private banks and pension funds to divest from the fossil industry and to reinvest that money in social and/or green projects and businesses.

2: End all fossil fuel subsidies

Ending fossil fuel subsidies: fast price drops and scaling up existing sustainable technology

Still more subsidies go to the fossil industry than to climate policy. The Dutch government even increased the subsidy for gas production in December 2020. Subsidies to the fossil industry give a harmful industry an unwanted and unfair advantage in the market. If these subsidies are abolished and if that amount is partly invested in the clean solutions that already exist, fossil fuel becomes more expensive and climate-friendly alternatives cheaper. That could trigger an acceleration in technological development that, according to Otto’s article, could reduce global greenhouse gases by 4.4% to 21% annually. Oil Change International has calculated that if the Netherlands immediately starts abolishing fossil subsidies and then reinvests 20% in energy efficiency, 10% in renewable energy and 50% in social safety nets, this could already reduce Dutch emissions by 7.7% by 2025. In this way, both climate change and social inequality can be fought without extra costs, according to Oil Change International. This is partly why Both Ends, Greenpeace, Milieudefensie, Oil Change International and Extinction Rebellion are campaigning against fossil subsidies.

We are asking the new cabinet:

to accelerate the social tipping point by stopping fossil subsidies and investing the billions that are released as a result in sustainable developments. The Netherlands has joined the Friends of fossil fuel subsidy reform group May 19, 2021 – a club of countries promoting the end of fossil subsidies. We expect NL, as a new member of the coalition, to take quick action to stop Dutch subsidies.

3: Climate education

Climate education: knowledge, shifting norms and values, and growth of social support

Climate education is now often incidental, teacher-dependent, or even derived from the fossil industry. The current Dutch curriculum is outdated and not up to date; it has not changed since 2007. Climate and sustainability deserve a fundamental place in the curriculum but also in the operations and the building of the school. At the same time, research shows that lack of knowledge about climate change prevents people from taking action for the climate. Good and independent climate education can have a direct effect on students as well as on their families and social environment. Moreover, a social tipping point can arise as soon as climate-conscious students enter the labor market, including in decisive and political positions. That is why the Dutch Academy for Sustainable Education, Teachers for Climate, Youth for Climate and Fridays for Future advocate independent climate education.

We ask the new cabinet: 

to accelerate this social tipping point by giving climate and sustainability for both current and future generations as well as non-human life a fundamental place in the curriculum and the operations and building of the school. This education must be independent.

4: Ban on fossil fuel advertising

Banning fossil fuel advertising: shifting norms and values and growing social support

A ban on fossil fuel advertisements is mentioned under the heading of “restrictions on the fossil industry” that can bring about a societal shift. An advertising ban de-normalizes the fossil industry and the use of fossil fuel for air travel and fuel cars and thus changes social norms. That a ban on fossil advertising is a social tipping point measure illustrates Amsterdam’s decision to ban fossil advertising. That news went around the world and since then many cities at home and abroad want the same. That is why Fossil Free Advertising and Greenpeace call for a nationwide ban on fossil advertising.

We ask the new cabinet:

to accelerate this social tipping point with a law that bans advertising, sponsoring and marketing for the fossil fuel industry, air travel and polluting cars. Just as advertising for tobacco is banned.

5: Decentralization of the energy system

Decentralization of the energy system: mutual exchange of energy, fair energy tax system and prevention of fossil lock-in

Another promising social tipping point, according to Otto, is the decentralization of energy. If the government enables citizens to regulate their own electricity and heat, this will result in 100% reductions locally. New investments in fossil infrastructure must be stopped in order to prevent a so-called ‘lock-in’. Otherwise society will be stuck with fossil fuels for decades to come. That is why The Hague Fossil Free is campaigning against the construction of a pipeline that would deliver heat from the fossil industry to homes in The Hague. Urgenda has been making houses energy-neutral for almost 10 years now, and is running up against a shortage of technical people and capacity shortages at network companies.

We are asking the new cabinet:

to accelerate this social tipping point by also setting up cooperative legislation for heat and electricity, focusing on local sustainable heat and electricity and systems through which citizens can exchange this energy. In addition, there should be no more tax breaks for large-scale energy consumers (equal treatment) and flexible tax rates for the storage of heat and electricity. We also ask the government for measures that increase the potential of green suppliers. They play a key role in the green movement by investing in local energy projects, stimulating local ownership and contributing to the professionalization of energy cooperatives.

Self-reinforcing effect

Each of the proposed measures has an effect. And with each additional social tipping point measure, that effect is amplified. That is the power of social tipping point measures. For example, the effect of climate education is strengthened by a ban on fossil advertising, lawsuits and other prohibitions against the fossil industry. It also works the other way around: Otto warns that the rapid effect of divestment evaporates if fossil subsidies remain in place and if social norms and values do not change. Then the basis on which the quick divestment success can be grounded will be missing.

The added value of a Social Tipping Point Strategy – over separate measures – is therefore that they reinforce each other. In this letter we mention only a few of the many social tipping point interventions from the article by Otto et al.

Some others include:

  • Growing perceptions that fossil fuel is immoral. The realization that the choices we make in the Netherlands are already threatening the existence of people and nature in places where fossil fuel is extracted. Moreover, climate change hits people hardest in countries that have contributed the least to climate change themselves and also do not have the money to protect themselves against its effects.
    The same goes for people who have not yet been born, ecosystems and animals. Otto writes that history has shown that social and moral norms can influence human behavior on a large scale, for example in the abolition of slavery.
  • put the responsibility for circularity on the producer
  • mandatory climate label that lists the climate damage of each product or service
  • another way of measuring economic success
  • grassroots movements that organize protest
  • sustainable building and a different organization of municipalities
  • convincing narratives also about the indigenous perspective on nature

Otto sees both potential and evidence in the rapidly growing global grassroots movements such as Fridays for Future and Extinction Rebellion that social norms and values are already shifting. DeGoedeZaak and Grandparents for Climate are also working toward such a tipping point.

our call

on the new cabinet

We desperately need the government to reach social tipping points

Many initiatives that can set social tipping points in motion come from society as yet. For example, none of the above interventions for which the undersigned advocates are government policies. What’s more, the government unfortunately still sees the ‘most scrappy’ fossil industry as a partner and even invited them as a shining example of change on the very first National Climate Day, while study after study shows that they are nowhere near in line with the Paris targets.

In climate policy, the government also tends to favor technology that is only achievable or sustainable in the long term. But the tipping points in the climate system do not give us room to wait for new technological promises that will only come to market in twenty years. If we do nothing now, we will be out of control within a decade. Nor do we have the luxury of leaving a social snowball effect to NGOs and grassroots movements with volunteers.

We need the central government to accelerate the technology that is already there.

We need the central government to accelerate the technology that is already there. We need the new cabinet to use strategic and effective policies to set social tipping points in motion that will ensure (with technological and social change) that the Paris goal of 1.5C degrees will be achieved.

Derk Loorbach (professor of socio-economic transitions at DRIFT and signatory of this letter), adds that the government can capitalize on events such as the earthquakes in Groningen to implement changes rather than slowing them down: “I call on the government to take climate science seriously and thus be more ambitious. The government should design policy in such a way that it anticipates momentum. Then it can use the event to take a step forward. Also, the government should push through the measures mentioned above, starting with banning fossil advertising.”

Opportunity for integrated climate policy without a price tag

Precisely because social tipping points become more effective when they reinforce each other, this offers the government a great opportunity to design smart, integrated and coherent policies to meet the Paris goal. Moreover, unlike, for example, CO2 storage under the North Sea, social tipping point measures are often climate measures that do not carry a price tag and sometimes even generate money. Abolishing fossil subsidies frees up billions that can be directly invested in climate-friendly solutions, such as a decentralized energy system. A ban on fossil advertising, climate education and climate labels save money because they prevent emissions and also increase support for climate policies. The good news is that many political parties have already included separate social tipping point measures in their recent election manifestos; abolishing fossil subsidies, banning fossil advertising, climate education, divestment.

The Hague is also ready for it!
