The rare spots of good news on climate change


The deadly consequences of climate change only grew clearer this year, as record-shattering heat waves, floods, and wildfires killed thousands and strained the limits of our disaster responders.

In the closing days of 2021, scientists warned that the eastern ledge of a Florida-size glacier is about to snap off of Antarctica and US legislators found they may have flubbed their best chance in a decade to enact sweeping climate policies.

But amid these stark signs, there were also indications that momentum is beginning to build behind climate action. Indeed, there’s good reason now to believe that the world could at least sidestep the worst dangers of global warming.

Princeton energy researcher Jesse Jenkins accurately, and colorfully, pinpointed the weird moment we’ve arrived at in a recent tweet: “We’re no longer totally f$%@ed. But we’re also far from totally unf$@%*ed!”

To be sure, the limited progress isn’t nearly enough. We’ve taken far too long to begin making real changes. World events and politics could still slow or reverse the trends. And we can’t allow a tiny bit of progress in the face of a generational challenge to ease the pressures for greater action.

But it’s worth highlighting and reflecting on the advances the world has made, because it demonstrates that it can be done—and could provide a template for achieving more.

Momentum

So what are the signs of progress amid the climate gloom?

The grimmest scenarios that many fretted about just a few years ago look increasingly unlikely. That includes the 4 or 5 °C of warming this century that I and others previously highlighted as a possibility.

The UN climate panel’s earlier high-end emissions scenario, known as RCP 8.5, had found that global temperatures could rise more than 5 °C by 2100. Those assumptions have been frequently included in studies assessing the risks of climate change, delivering the eye-catching top-end results often cited in the press. (Guilty.)

Some argue that it wasn’t all that plausible in the first place. And the scenario seems increasingly far-fetched given the rapid shift away from coal-fired power plants, initially to lower-emitting natural gas but increasingly toward carbon-free wind and solar.

Global emissions may have already flattened when taking into account recent revisions to land-use changes, meaning updated tallies of the forests, farmlands, and grasslands the world is gaining and losing.

Today, if you layer in all the climate policies already in place around the world, we’re now on track for 2.7 °C of warming this century as a middle estimate, according to Climate Action Tracker. (Similarly, the UN’s latest report found that the planet is likely to warm between 2.1 and 3.5 °C under its “intermediate” emissions scenario.)

If you assume that nations will meet their emissions pledges under the Paris agreement, including the new commitments timed around the recent UN summit in Glasgow, the figure goes down to 2.4 °C. And if every country pulls off its net-zero emissions targets by around the middle of the century, it drops to 1.8 °C.

Given the increasingly strict climate policies and the plummeting costs of solar and wind, we’re about to witness an absolute boom in renewables development. The International Energy Agency, well known for underestimating the growth of renewables in the past, now says that global capacity will rise more than 60% by 2026. At that point, solar, wind, hydroelectric dams, and other renewables facilities will rival the worldwide capacity of fossil-fuel and nuclear plants.

Sales of new electric vehicles, bumping along in the low single digits for years, are also taking off. They’ll reach around 5.6 million this year, leaping more than 80% over 2020 figures, as automakers release more models and governments enact increasingly aggressive policies, according to BloombergNEF.

Electric vehicles climbed from 2.8% of new sales in the first half of 2019 to 7% during the first half of 2021, with particularly large gains in China and Europe. Zero-emissions vehicles will make up nearly 30% of all new purchases by 2030, the research firm projects.

Progress

Meanwhile, there are plenty of signs of technological progress. Researchers and companies are figuring out ways to produce carbon-free steel and cement. Plant-based meat alternatives are getting tastier and more popular faster than anyone expected. Businesses are building increasingly large plants to suck carbon dioxide out of the air. Venture capital investments into climate and clean-tech startups have risen to levels never before seen, totaling more than $30 billion through the third quarter, according to PitchBook.

And here’s an important and counterintuitive finding: While dangerous, extreme weather events are becoming increasingly common or severe, the world seems to be getting a lot better at keeping people safer from them. The average number of deaths from natural disasters has generally dropped sharply in recent decades.

“We have better technologies to predict storms, wildfires, and floods; infrastructure to protect ourselves; and networks to cooperate and recover when a disaster does strike,” noted Hannah Ritchie, head of research at Our World of Data, in an recent Wired UK essay, citing her own research.

This provides additional hope that with the right investments into climate adaption measures like seawalls and community cooling centers, we’ll be able to manage some of the increased risks we’ll face. Rich nations that have emitted the most greenhouse gases, however, must provide financial assistance to help poor countries bolster their defenses.

A realistic baseline

Some folks have seized on these improving signs to argue that climate change isn’t going to be all that bad. That’s nonsense. The world is, by any measure, still dramatically underreacting to the rising risks.

A planet that’s nearly 3 °C hotter would be a far more dangerous and unpredictable place. Those temperatures threaten to wipe out coral reefs, sink major parts of our coastal cities and low-lying islands, and subject millions of people to far greater risks of extreme heat waves, droughts, famines, and floods.

In addition, we could still be underestimating how sensitive the atmosphere is to greenhouse gases, as well as the spiraling impacts of climate tipping points and the dangers that these higher temperatures bring. And there’s no guarantee that nations won’t backtrack on their policies and commitments amid economic shocks, conflicts, and other unpredictable events.

But to be sure, a 3 °C warmer world is a much more livable place than a 5 °C warmer one, and a far more promising starting line for getting to 2 °C.

“The point isn’t to say that that’s a good outcome,” says Zeke Hausfather, director of climate and energy at the Breakthrough Institute. “The point is, that’s the baseline we’re working with now. And it’s easier to imagine much more rapid declines from there.”

In some ways, it’s especially notable that the world has made this much progress without sweeping climate policies in many nations, and despite all the poisoned, partisan politics surrounding climate change.

The shifts to natural gas, then solar and wind, and increasingly EVs were all aided by government support, including loans, subsidies, and other policies that pushed the underlying technologies into the marketplace. And the business-driven scale-up process rapidly cut the costs of those technologies, helping them become ever more attractive.

Increasingly competitive and business-friendly clean alternatives promise to simplify the politics of further climate action. If more and more nations enact increasingly aggressive policies—carbon taxes, clean-energy standards, or far more funding for research and demonstration projects—we’ll drive down emissions ever faster.

The world isn’t ending

There are other reasons to take note of the modest progress we are making.

Progressive US politicians now casually repeat the claim that climate change is an “existential threat,” suggesting it will wipe out all of humanity. After a 2018 UN report noted that global warming could reach 1.5 °C between 2030 and 2052, climate activists and media outlets contorted that finding into versions of “We have 12 years to save the planet!”

If so, it would now be down to nine. But 1.5 °C isn’t some scientifically determined threshold of societal collapse. Though the world will miss that goal, it remains crucial to fight for every additional half-degree of warming beyond it, each of which brings steadily higher risks.

Meanwhile, climate research does not suggest that the 3 °C of warming we’re now roughly on target for would transform the entire planet into some uninhabitable hellscape.

So no, climate change is not an existential threat.

But that sentiment has certainly taken hold. Earlier this year, researchers at the University of Bath surveyed 10,000 young people, aged 16 to 25, in 10 countries to assess the levels of “climate anxiety.” More than half, 56%, agreed with the statement “Humanity is doomed.”

It’s standard stuff for politicians and activists to overstate dangers and demands, in the hopes of pushing toward some compromise solution. And the growing climate fears and the increasingly influential climate activist movement have undoubtedly put greater pressures on politicians and business to take these issues more seriously, helping to drive some the policy changes we’ve seen. They deserve real credit for that.

But insisting that the world is at the edge of collapse, when it’s not, is a terrible message for young people and carries some real risks as well. It clearly undermines credibility. It could lead some people to simply lose hope. And it could compel others to demand extreme and often counterproductive responses.

“It’s time to stop telling our children that they’re going to die from climate change,” Ritchie wrote. “It’s not only cruel, it might actually make it more likely to come true.”

When people don’t see a “reasonable path forward,” they begin to rationalize unreasonable ones.

Among those I hear with surprising frequency: We must shut down all fossil-fuel infrastructure, and end oil and gas extraction now. We must fix everything with today’s technologies and reject the “predatory delay” tactic of continued investment in clean-energy innovation. We have to halt consumption, construction, and economic development. Or even: We must smash the global capitalist system that caused all the problems!

Balancing the trade-offs

None of that strikes me as somehow more politically feasible than fixing our energy systems.

We do have to shut down fossil-fuel plants, replace vehicles, and switch to new methods of producing food, cement, steel, and other goods—and relatively quickly. But we have to do it by developing alternatives that don’t pump greenhouse gases into the atmosphere.

If we adjust the goalpost back to 2 °C, which is regrettable but only realistic at this point, we have several decades yet to carry out the transformation required. Under a modest emissions scenario, the world won’t exceed that threshold until around 2052 as a middle estimate, Hausfather’s analysis of the latest UN climate report suggests.

What we can’t do is just shut down the infrastructure that drives the global economy—not without massive damage to jobs, food, health care, and safety. We’d sacrifice the economic resources we need to develop a more sustainable economy, as well as to make our communities more resilient to the coming climate dangers.

Why I became a TechTrekker

My senior spring in high school, I decided to defer my MIT enrollment by a year. I had always planned to take a gap year, but after receiving the silver tube in the mail and seeing all my college-bound friends plan out their classes and dorm decor, I got cold feet. Every time I mentioned my plans, I was met with questions like “But what about school?” and “MIT is cool with this?”

Yeah. MIT totally is. Postponing your MIT start date is as simple as clicking a checkbox. 

Sofia Pronina (right) was among those who hiked to the Katla Glacier during this year’s TechTrek to Iceland.

Now, having finished my first year of classes, I’m really grateful that I stuck with my decision to delay MIT, as I realized that having a full year of unstructured time is a gift. I could let my creative juices run. Pick up hobbies for fun. Do cool things like work at an AI startup and teach myself how to create latte art. My favorite part of the year, however, was backpacking across Europe. I traveled through Austria, Slovakia, Russia, Spain, France, the UK, Greece, Italy, Germany, Poland, Romania, and Hungary. 

Moreover, despite my fear that I’d be losing a valuable year, traveling turned out to be the most productive thing I could have done with my time. I got to explore different cultures, meet new people from all over the world, and gain unique perspectives that I couldn’t have gotten otherwise. My travels throughout Europe allowed me to leave my comfort zone and expand my understanding of the greater human experience. 

“In Iceland there’s less focus on hustle culture, and this relaxed approach to work-life balance ends up fostering creativity. This was a wild revelation to a bunch of MIT students.”

When I became a full-time student last fall, I realized that StartLabs, the premier undergraduate entrepreneurship club on campus, gives MIT undergrads a similar opportunity to expand their horizons and experience new things. I immediately signed up. At StartLabs, we host fireside chats and ideathons throughout the year. But our flagship event is our annual TechTrek over spring break. In previous years, StartLabs has gone on TechTrek trips to Germany, Switzerland, and Israel. On these fully funded trips, StartLabs members have visited and collaborated with industry leaders, incubators, startups, and academic institutions. They take these treks both to connect with the global startup sphere and to build closer relationships within the club itself.

Most important, however, the process of organizing the TechTrek is itself an expedited introduction to entrepreneurship. The trip is entirely planned by StartLabs members; we figure out travel logistics, find sponsors, and then discover ways to optimize our funding.

In organizing this year’s trip to Iceland, we had to learn how to delegate roles to all the planners and how to maintain morale when making this trip a reality seemed to be an impossible task. We woke up extra early to take 6 a.m. calls with Icelandic founders and sponsors. We came up with options for different levels of sponsorship, used pattern recognition to deduce the email addresses of hundreds of potential contacts at organizations we wanted to visit, and all got scrappy with utilizing our LinkedIn connections.

And as any good entrepreneur must, we had to learn how to be lean and maximize our resources. To stretch our food budget, we planned all our incubator and company visits around lunchtime in hopes of getting fed, played human Tetris as we fit 16 people into a six-person Airbnb, and emailed grocery stores to get their nearly expired foods for a discount. We even made a deal with the local bus company to give us free tickets in exchange for a story post on our Instagram account.

How ubiquitous keyboard software puts hundreds of millions of Chinese users at risk

For millions of Chinese people, the first software they download onto devices is always the same: a keyboard app. Yet few of them are aware that it may make everything they type vulnerable to spying eyes. 

QWERTY keyboards are inefficient as many Chinese characters share the same latinized spelling. As a result, many switch to smart, localized keyboard apps to save time and frustration. Today, over 800 million Chinese people use third-party keyboard apps on their PCs, laptops, and mobile phones. 

But a recent report by the Citizen Lab, a University of Toronto–affiliated research group, revealed that Sogou, one of the most popular Chinese keyboard apps, had a massive security loophole. Read the full story.

Why we should all be rooting for boring AI

Earlier this month, the US Department of Defense announced it is setting up a Generative AI Task Force, aimed at “analyzing and integrating” AI tools such as large language models across the department. It hopes they could improve intelligence and operational planning. 

But those might not be the right use cases, writes our senior AI reporter Melissa Heikkila. Generative AI tools, such as language models, are glitchy and unpredictable, and they make things up. They also have massive security vulnerabilities, privacy problems, and deeply ingrained biases. 

Applying these technologies in high-stakes settings could lead to deadly accidents where it’s unclear who or what should be held responsible, or even why the problem occurred. The DoD’s best bet is to apply generative AI to more mundane things like Excel, email, or word processing. Read the full story.

The ice cores that will let us look 1.5 million years into the past

To better understand the role atmospheric carbon dioxide plays in Earth’s climate cycles, scientists have long turned to ice cores drilled in Antarctica, where snow layers accumulate and compact over hundreds of thousands of years, trapping samples of ancient air in a lattice of bubbles that serve as tiny time capsules. 

By analyzing those cores, scientists can connect greenhouse-gas concentrations with temperatures going back 800,000 years. Now, a new European-led initiative hopes to eventually retrieve the oldest core yet, dating back 1.5 million years. But that impressive feat is still only the first step. Once they’ve done that, they’ll have to figure out how they’re going to extract the air from the ice. Read the full story.

October 2022

Since its birth in the late 2000s, effective altruism has aimed to answer the question “How can those with means have the most impact on the world in a quantifiable way?”—and supplied methods for calculating the answer.

It’s no surprise that effective altruisms’ ideas have long faced criticism for reflecting white Western saviorism, alongside an avoidance of structural problems in favor of abstract math. And as believers pour even greater amounts of money into the movement’s increasingly sci-fi ideals, such charges are only intensifying. Read the full story.

Why we should all be rooting for boring AI


This story originally appeared in The Algorithm, our weekly newsletter on AI. To get stories like this in your inbox first, sign up here.

I’m back from a wholesome week off picking blueberries in a forest. So this story we published last week about the messy ethics of AI in warfare is just the antidote, bringing my blood pressure right back up again. 

Arthur Holland Michel does a great job looking at the complicated and nuanced ethical questions around warfare and the military’s increasing use of artificial-intelligence tools. There are myriad ways AI could fail catastrophically or be abused in conflict situations, and there don’t seem to be any real rules constraining it yet. Holland Michel’s story illustrates how little there is to hold people accountable when things go wrong.  

Last year I wrote about how the war in Ukraine kick-started a new boom in business for defense AI startups. The latest hype cycle has only added to that, as companies—and now the military too—race to embed generative AI in products and services. 

Earlier this month, the US Department of Defense announced it is setting up a Generative AI Task Force, aimed at “analyzing and integrating” AI tools such as large language models across the department. 

The department sees tons of potential to “improve intelligence, operational planning, and administrative and business processes.” 

But Holland Michel’s story highlights why the first two use cases might be a bad idea. Generative AI tools, such as language models, are glitchy and unpredictable, and they make things up. They also have massive security vulnerabilities, privacy problems, and deeply ingrained biases.  

Applying these technologies in high-stakes settings could lead to deadly accidents where it’s unclear who or what should be held responsible, or even why the problem occurred. Everyone agrees that humans should make the final call, but that is made harder by technology that acts unpredictably, especially in fast-moving conflict situations. 

Some worry that the people lowest on the hierarchy will pay the highest price when things go wrong: “In the event of an accident—regardless of whether the human was wrong, the computer was wrong, or they were wrong together—the person who made the ‘decision’ will absorb the blame and protect everyone else along the chain of command from the full impact of accountability,” Holland Michel writes. 

The only ones who seem likely to face no consequences when AI fails in war are the companies supplying the technology.

It helps companies when the rules the US has set to govern AI in warfare are mere recommendations, not laws. That makes it really hard to hold anyone accountable. Even the AI Act, the EU’s sweeping upcoming regulation for high-risk AI systems, exempts military uses, which arguably are the highest-risk applications of them all. 

While everyone is looking for exciting new uses for generative AI, I personally can’t wait for it to become boring. 

Amid early signs that people are starting to lose interest in the technology, companies might find that these sorts of tools are better suited for mundane, low-risk applications than solving humanity’s biggest problems.

Applying AI in, for example, productivity software such as Excel, email, or word processing might not be the sexiest idea, but compared to warfare it’s a relatively low-stakes application, and simple enough to have the potential to actually work as advertised. It could help us do the tedious bits of our jobs faster and better.

Boring AI is unlikely to break as easily and, most important, won’t kill anyone. Hopefully, soon we’ll forget we’re interacting with AI at all. (It wasn’t that long ago when machine translation was an exciting new thing in AI. Now most people don’t even think about its role in powering Google Translate.) 

That’s why I’m more confident that organizations like the DoD will find success applying generative AI in administrative and business processes. 

Boring AI is not morally complex. It’s not magic. But it works. 

Deeper Learning

AI isn’t great at decoding human emotions. So why are regulators targeting the tech?

Amid all the chatter about ChatGPT, artificial general intelligence, and the prospect of robots taking people’s jobs, regulators in the EU and the US have been ramping up warnings against AI and emotion recognition. Emotion recognition is the attempt to identify a person’s feelings or state of mind using AI analysis of video, facial images, or audio recordings. 

But why is this a top concern? Western regulators are particularly concerned about China’s use of the technology, and its potential to enable social control. And there’s also evidence that it simply does not work properly. Tate Ryan-Mosley dissected the thorny questions around the technology in last week’s edition of The Technocrat, our weekly newsletter on tech policy.
