Bill Gates' New Book Has a Stark and Simple Message for the World
By Tim Radford
London, 15 February, 2021. Bill Gates − yes, that Bill Gates − has for years been financing studies in geo-engineering: he calls it a "Break Glass in Case of Emergency" kind of tool.
But he also says, in a new book, How to Avoid a Climate Disaster: the Solutions We Have and the Breakthroughs We Need, that he has put much more money into the challenge of adapting to and mitigating climate change − driven by global heating powered by greenhouse emissions that are a consequence of our dependence on fossil fuels.
The founder of Microsoft, now a philanthropist, says all geo-engineering approaches − to dim the sunlight, perhaps, or make clouds brighter − turn out to be relatively cheap compared with the scale of the problems ahead for the world. All the effects are relatively short-lived, so there might be no long-term impacts.
But the third thing they have in common is that the technical challenges to implementing them would be as nothing compared with the political hurdles such ambitions must face.
Not for Dummies
There are some very encouraging things about this disarming book, and one of them is that on every page it addresses the messy uncertainties of the real world, rather than an ideal set of solutions.
People who have already thought a lot about the hazards and complexities of global temperature rise might be tempted to dismiss it as Climate Change for Dummies. They'd be wrong.
First, Gates addresses a global audience that includes (for instance) U.S. Republican voters, fewer than one in four of whom understand that climate change is a consequence of what humans have done.
Then Gates writes as an engineer. He starts from the basics and arrives swiftly and by the shortest route at a series of firm conclusions: sophisticated, but still outlined with considerable clarity and a happy trick of pinning big answers to down-to-earth analogies.
Crude oil, he calculates, "is cheaper than a soft drink." By mid-century "climate change could be just as deadly as Covid-19, and by 2100 it could be five times as deadly."
And population growth creates prodigious demands: by 2060, the world's building stock will double. "That's like putting up another New York City every month for 40 years."
I call it a disarming book: yes, he concedes that the world is not lacking in rich men with big ideas about what other people should do; yes, he flew a private plane to the Paris Conference in 2015. He doesn't deny being a rich guy with an opinion and an "absurdly high" carbon footprint. But he believes it is an informed opinion, and he's always trying to learn more.
And then he gets on with clarifying the big challenges. Yes, there's no choice: the world has to get to zero-carbon. It's going to be difficult to achieve the technologies, the political will, the international consensus. Humans have to accomplish something gigantic, much faster than anything ever done before.
He turns to the details: the questions that need to be addressed; the separate problems of electrical energy, of manufacture, of diet and agriculture, of transport, of adaptation; government policy, citizen choice and so on.
He touches on biofuels, nuclear power ("this might sound self-serving, given that I own an advanced nuclear company"), global development, global health, international co-operation and individual choices, all with the same brisk clarity. There already exists a huge literature of climate change: this is a useful addition.
That may be because he keeps the message simple from the start. Right now humans add 51 billion tons of greenhouse gases to the atmosphere every year. To avoid the worst effects of climate change, we have to emit none.
"There are two numbers you need to know about climate change," he writes in his opening sentences. "The first is 51 billion. The second is zero."

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.
Comparing rime ice and glaze ice shows how each changes the texture of the blade. Gao, Liu and Hu, 2021, CC BY-ND
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>
