The move, which has not been previously reported on, marks the first federally coordinated US effort of this kind. It could set the stage for more funding and research into the feasibility, benefits, and risks of such interventions. The effort may also contribute to the perception that geoengineering is an appropriate and important area of research as global temperatures rise.
Solar geoengineering encompasses a range of different approaches. The one that’s gained the most attention is using planes or balloons to disperse tiny particles in the stratosphere. These would then—in theory—reflect back enough sunlight to ease warming, mimicking the effect of massive volcanic eruptions in the past. Some research groups have also explored whether releasing certain particles could break up cirrus clouds, which trap heat against the Earth, or make low-lying marine clouds more reflective.
The 2022 federal appropriations act, signed by President Biden in March, directs his Office of Science and Technology Policy to develop a cross-agency group to coordinate research on such climate interventions, in partnership with NASA, the National Oceanic and Atmospheric Administration (NOAA), and the Department of Energy.
The measure calls for the group to create a research framework to “provide guidance on transparency, engagement, and risk management for publicly funded work in solar geoengineering research.” Specifically, it directs NOAA to support the Office of Science and Technology Policy in developing a five-year plan that will, among other things, define research goals for the field, assess the potential hazards of such climate interventions, and evaluate the level of federal investments required to carry out that work.
Geoengineering was long a taboo topic among scientists, and some argue it should remain one. There are questions about potential environmental side effects, and concerns that the impacts will be felt unevenly in different parts of the globe. It’s not clear how the world will grapple with tricky questions regarding global governance, including who should make decisions about whether to deploy such powerful tools and what global average temperatures we should aim for. Some feel that geoengineering is too dangerous to ever try or even to investigate, arguing that just talking about the possibility could make the need to address the underlying causes of climate change feel less urgent.
But as the threat of climate change grows and major nations fail to make rapid progress on emissions, more researchers, universities, and nations are seriously exploring the potential effects of these approaches. A handful of prominent scientific groups, in turn, have called for stricter standards to guide that work, more money to do it, or both. That includes the National Academies of Sciences, Engineering, and Medicine, which last year recommended setting up a US solar geoengineering research program with an initial investment of $100 million to $200 million over five years.
Proponents of geoengineering research, while stressing that cutting emissions must remain the highest priority, say we should explore these possibilities because they may meaningfully reduce the dangers of climate change. They note that as heat waves, droughts, famines, wildfires, and other extreme events become more common or severe, these sorts of climate interventions may be among the few means available to rapidly ease widespread human suffering or ecological calamities.
In a statement, the Office of Science and Technology Policy confirmed that it has created an interagency working group, as called for under the federal funding bill. It includes representatives of 10 research and mission agencies, including NOAA, NASA, and the Department of Energy.

Methodology: The Blue Technology Barometer 2022/23
Now in its second year, the Blue Technology Barometer assesses and ranks how each of the world’s largest
maritime economies promotes and develops blue (marine-centered) technologies that help reverse the impact of
climate change on ocean ecosystems, and how they leverage ocean-based resources to reduce greenhouse gases and
other effects of climate change.
To build the index, MIT Technology Review Insights compiled 20 quantitative and qualitative data indicators
for 66 countries and territories with coastlines and maritime economies. This included analysis of select
datasets and primary research interviews with global blue technology innovators, policymakers, and
international ocean sustainability organizations. Through trend analysis, research, and a consultative
peer-review process with several subject matter experts, weighting assumptions were assigned to determine the
relative importance of each indicator’s influence on a country’s blue technology leadership.
These indicators measure how each country or territory’s economic and maritime industries have affected its
marine environment and how quickly they have developed and deployed technologies that help improve ocean
health outcomes. Policy and regulatory adherence factors were considered, particularly the observance of
international treaties on fishing and marine protection laws.
The indicators are organized into four pillars, which evaluate metrics around a sustainability theme. Each
indicator is scored from 1 to 10 (10 being the best performance) and is weighted for its contribution to its
respective pillar. Each pillar is weighted to determine its importance in the overall score. As these research
efforts center on countries developing blue technology to promote ocean health, the technology pillar is
ranked highest, at 50% of the overall score.
The four pillars of the Blue Technology Barometer are:
Carbon emissions resulting from maritime activities and their relative growth. Metrics in this pillar also
assess each country’s efforts to mitigate ocean pollution and enhance ocean ecosystem health.
Efforts to promote sustainable fishing activities and increase and maintain marine protected areas.
Progress in fostering the development of sustainable ocean technologies across several relevant fields:
- Clean innovation scores from MIT Technology Review Insights’ Green Future Index 2022.
- A tally of maritime-relevant patents and technology startups.
- An assessment of each economy’s use of technologies and tech-enabled processes that facilitate ocean

What Shanghai protesters want and fear
You may have seen that nearly three years after the pandemic started, protests have erupted across the country. In Beijing, Shanghai, Urumqi, Guangzhou, Wuhan, Chengdu, and more cities and towns, hundreds of people have taken to the streets to mourn the lives lost in an apartment fire in Urumqi and to demand that the government roll back its strict pandemic policies, which many blame for trapping those who died.
It’s remarkable. It’s likely the largest grassroots protest in China in decades, and it’s happening at a time when the Chinese government is better than ever at monitoring and suppressing dissent.
Videos of these protests have been shared in real time on social media—on both Chinese and American platforms, even though the latter are technically blocked in the country—and they have quickly become international front-page news. However, discussions among foreigners have too often reduced the protests to the most sensational clips, particularly ones in which protesters directly criticize President Xi Jinping or the ruling party.
The reality is more complicated. As in any spontaneous protest, different people want different things. Some only want to abolish the zero-covid policies, while others have made direct calls for freedom of speech or a change of leadership.
I talked to two Shanghai residents who attended the protests to understand what they experienced firsthand, why they went, and what’s making them anxious about the thought of going again. Both have requested we use only their surnames, to avoid political retribution.
Zhang, who went to the first protest in Shanghai after midnight on Saturday, told me he was motivated by a desire to let people know his discontent. “Not everyone can silently suffer from your actions,” he told me, referring to government officials. “No. People’s lives have been really rough, and you should reflect on yourself.”
In the hour that he was there, Zhang said, protesters were mostly chanting slogans that stayed close to opposing zero-covid policies—like the now-famous line “Say no to covid tests, yes to food. No to lockdowns, yes to freedom,” which came from a protest by one Chinese citizen, Peng Lifa, right before China’s heavily guarded party congress meeting last month.
While Peng hasn’t been seen in public since, his slogans have been heard and seen everywhere in China over the past week. Relaxing China’s strict pandemic control measures, which often don’t reflect a scientific understanding of the virus, is the most essential—and most agreed-upon—demand.
Biotech labs are using AI inspired by DALL-E to invent new drugs
Today, two labs separately announced programs that use diffusion models to generate designs for novel proteins with more precision than ever before. Generate Biomedicines, a Boston-based startup, revealed a program called Chroma, which the company describes as the “DALL-E 2 of biology.”
At the same time, a team at the University of Washington led by biologist David Baker has built a similar program called RoseTTAFold Diffusion. In a preprint paper posted online today, Baker and his colleagues show that their model can generate precise designs for novel proteins that can then be brought to life in the lab. “We’re generating proteins with really no similarity to existing ones,” says Brian Trippe, one of the co-developers of RoseTTAFold.
These protein generators can be directed to produce designs for proteins with specific properties, such as shape or size or function. In effect, this makes it possible to come up with new proteins to do particular jobs on demand. Researchers hope that this will eventually lead to the development of new and more effective drugs. “We can discover in minutes what took evolution millions of years,” says Gevorg Grigoryan, CEO of Generate Biomedicines.
“What is notable about this work is the generation of proteins according to desired constraints,” says Ava Amini, a biophysicist at Microsoft Research in Cambridge, Massachusetts.
Proteins are the fundamental building blocks of living systems. In animals, they digest food, contract muscles, detect light, drive the immune system, and so much more. When people get sick, proteins play a part.
Proteins are thus prime targets for drugs. And many of today’s newest drugs are protein based themselves. “Nature uses proteins for essentially everything,” says Grigoryan. “The promise that offers for therapeutic interventions is really immense.”
But drug designers currently have to draw on an ingredient list made up of natural proteins. The goal of protein generation is to extend that list with a nearly infinite pool of computer-designed ones.
Computational techniques for designing proteins are not new. But previous approaches have been slow and not great at designing large proteins or protein complexes—molecular machines made up of multiple proteins coupled together. And such proteins are often crucial for treating diseases.
