These Are the ‘Positive’ Tipping Points That Could Slow Global Warming
By Mark McCord
- An academic paper suggests key tipping points can significantly reduce carbon emissions, which would help to slow global warming.
- Government policies are making coal uneconomical.
- Electric vehicle pricing structures have helped reduce the number of petrol and diesel cars on the world's roads.
There may be light at the end of the tunnel in the battle to reduce carbon emissions.
Governments and institutions could help halt carbon emissions with just a few carefully selected policy measures, according to a new paper, which looked at the experience of the energy industry and changing trends in road vehicle purchases.
If chosen properly and applied internationally, such "tipping points" could set off a series of other changes that snowball into a movement with enough critical mass to slow global warming and reduce natural disasters.
The paper, published in the journal Climate Policy, argues that actions taken within each industry created a cascade of further developments that helped reduce their carbon footprints.
"In complex systems – including human societies – tipping points can occur, in which a small perturbation transforms a system," wrote the paper's authors, Professor Tim Lenton, director of the Global Systems Institute (GSI) at the University of Exeter and Simon Sharpe, a deputy director in the UK Cabinet Office 26th session of the Conference of Parties (COP 26) unit.
"Crucially, activating one tipping point can increase the likelihood of triggering another at a larger scale, and so on."
Towards the Paris Agreement Targets

Such tipping points are hoped to help the world meet the targets of the 2015 Paris Agreement, in which 196 heads of state agreed to reduce global warming to within 2 degrees Celsius above pre-industrial levels, with a preferred target of 1.5 degrees. Were they achieved, experts say the positive impacts would be felt within two decades.
The accord strives for a climate-neutral world by the middle of this century. It's expected to be built upon at the United Nations Climate Change conference, or COP26, which is due to take place in November. The World Economic Forum's Climate Initiative strives also to offer globally linked solutions.
The report in Climate Policy explains how a combination of factors led to the tipping point that prompted the UK to decarbonize its power industry. They included the creation of a carbon tax, an EU scheme that made gas cheaper than coal and an investment strategy for renewable energy that made coal less economical.
"The power sector needs to decarbonize four times faster than its current rate, and the pace of the transition to zero-emission vehicles needs to double," Lenton said.
"Many people are questioning whether this is achievable. But hope lies in the way that tipping points can spark rapid change through complex systems."
Positive Tipping Points
Besides the UK, the authors of the paper cited Norway as an example of the nations that have acted to reduce greenhouse gases pumped out by motor vehicles.
Through government incentives, new electric vehicles (EV) in Norway are priced similarly to petrol and diesel cars. This has boosted sales of EVs to more than 50% of new car purchases, compared with 2%-3% worldwide.
China, the European Union (EU) and California are responsible for half of global car sales. Professor Lenton suggests that if they formed an international effort to redirect investment from conventional cars to EVs they could reduce costs, boost production and create a broader tipping point that would accelerate the reduction of fossil fuel use.
Lenton argues that if government action can lower the cost of financing renewables to below that of excavating coal, industries linked to transport, heating and power could all rapidly decarbonize.
That's good news because a new, more urgent, approach is needed to reduce the rate at which the global climate is warming, according to scientists.
2020 and 2016 Hottest Years on Record
Earlier this month, the EU's Copernicus Climate Change Service said 2020 had equaled 2016 as the hottest year on record.
A study published in Climate Dynamics said the planet could breach the threshold for global warming between 2027 and 2042, a decade earlier than previously thought.
"If either of these efforts – in power or road transport – succeed, the most important effect could be to tip perceptions of the potential for international cooperation to tackle climate change," Lenton said.

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
