A bright and airy hub for climate at MIT

Thursday, August 1, 2024

Seen from a distance, MIT’s Cecil and Ida Green Building (Building 54) — designed by renowned architect and MIT alumnus I.M. Pei ’40 — is one of the most iconic buildings on the Cambridge, Massachusetts, skyline. Home to the MIT Department of Earth, Atmospheric and Planetary Sciences (EAPS), the 21-story concrete structure soars over campus, topped with its distinctive spherical radar dome. Close up, however, it was a different story.A sunless, two-story, open-air plaza beneath the tower previously served as a nondescript gateway to the department’s offices, labs, and classrooms above. “It was cold and windy — probably the windiest place on campus,” EAPS department head Robert van der Hilst, the Schlumberger Professor of Earth and Planetary Sciences, told a packed auditorium inside the building in March. “You would pass through the elevators and disappear into the corridors, never to be seen again until the end of the day.”Van der Hilst was speaking at a dedication event to celebrate the opening of the renovated and expanded space, 60 years after the Green Building’s original dedication in 1964. In a dramatic transformation, the perpetually-shaded expanse beneath the tower has been filled with an airy, glassed-in structure that is as inviting as the previous space was forbidding.Designed to meet LEED-platinum certification, the newly-constructed Tina and Hamid Moghadam Building (Building 55) seems to float next to the Brutalist tower, its glass façade both opening up the interior and reflecting the sunlight and green space outside. The 300-seat auditorium within the original tower has been similarly transformed, bringing light and space to the newly dubbed Dixie Lee Bryant (1891) Lecture Hall, named after the first person to earn a geology degree at MIT.Catalyzing collaborationThe project is about more than updating an overlooked space. “The building we’re here to celebrate today does something else,” MIT President Sally Kornbluth said at the dedication.“In its lightness, in its transparency, it calls attention not to itself, but to the people gathered inside it. In its warmth, its openness, it makes room for culture and community. And it welcomes in those who don’t yet belong … as we take on the immense challenges of climate together,” she continued, referencing the recent launch of The Climate Project at MIT — a whole-of-MIT initiative to innovate bold solutions to climate change. In MIT’s famously decentralized structure, the Moghadam Building provides a new physical hub for students, scientists, and engineers interested in climate and the environment to congregate and share ideas.From the start, fostering this kind of multidisciplinary collaboration was part of Van der Hilst’s vision. In addition to serving as the flagship location for EAPS, Building 54 has long been the administrative home of the MIT-WHOI Joint Program in Oceanography/Applied Ocean Science and Engineering — a graduate program in partnership with Woods Hole Oceanographic Institute. With the addition of Building 55, EAPS has now been joined by the MIT Environmental Solutions Initiative (ESI) — a campus-wide program fostering education, outreach, and innovation in earth system science, urban infrastructure, and sustainability — and will welcome closer collaboration with Terrascope — a first-year learning community which invites its students to take on real-world environmental challenges.A shared vision comes to lifeThe building project dovetailed with the long-overdue refurbishment of the Green Building. After a multi-year fundraising campaign where Van der Hilst spearheaded the department’s efforts, the project received a major boost from lead donors Tina and Hamid Moghadam ’77, SM ’78, allowing the department to break ground in November 2021.In Moghadam, chair and CEO of Prologis, which owns 1.2 billion square feet of warehouses and other logistics infrastructure worldwide, EAPS found a fellow champion for climate and environmental innovation. By putting solar panels on the roofs of Prologis buildings, the company is now the second largest on-site producer of solar energy in the United States. “I don’t think there needs to be a trade-off between good sound economics and return on investment and solving climate change problems,” Moghadam said at the dedication. “The solutions that really work are the ones that actually make sense in a market economy.”Architectural firm AW-ARCH designed the Moghadam Building with a light touch, emphasizing spaciousness in contrast to the heavy concrete buildings that surround it. “The kind of delicacy and fragility of the thing is in some ways a depiction of what happens here,” said architect and co-founding partner Alex Anmahian at the dedication reception, giving a nod to the study of the delicate balance of the earth system itself. The sense is further illustrated by the responsiveness of the façade to the surrounding environment, which, depending on the time of day and quality of light, makes the glass alternately reflective and transparent.Inside, the 11,900-square foot pavilion is highly flexible and serves as a showcase for the science that happens in the labs and offices above. Central to the space is a 16-foot by 9-foot video wall featuring vivid footage of field work, lab research, data visualizations, and natural phenomena — visible even to passers-by outside. The video wall is counterposed to an unpretentious set of stair-step bleachers leading to the second floor that could play host to anything from a scientific lecture to a community pizza-and-movie night.Van der Hilst has referred to his vision for the atrium as a “campus living room,” and the furniture throughout is intentionally chosen to allow for impromptu rearrangements, providing a valuable public space on campus for students to work and socialize.The second level is similarly adaptable, featuring three classrooms with state-of-the-art teaching technologies that can be transformed from a single large space for a hackathon to intimate rooms for discussion.“The space is really meant for a yet unforeseen experience,” Anmahian says. “The reason it is so open is to allow for any possibility.”The inviting, dynamic design of the pavilion has also become an instant point of pride for the building’s inhabitants.

Together, the new Moghadam Building and refurbished Green Building form a vibrant new center to tackle pressing global concerns of sustainability and climate change.

The 300-seat auditorium within the original tower has been similarly transformed, bringing light and space to the newly dubbed Dixie Lee Bryant (1891) Lecture Hall, named after the first person to earn a geology degree at MIT.

Catalyzing collaboration

The project is about more than updating an overlooked space. “The building we’re here to celebrate today does something else,” MIT President Sally Kornbluth said at the dedication.

“In its lightness, in its transparency, it calls attention not to itself, but to the people gathered inside it. In its warmth, its openness, it makes room for culture and community.

A shared vision comes to life

The building project dovetailed with the long-overdue refurbishment of the Green Building. After a multi-year fundraising campaign where Van der Hilst spearheaded the department’s efforts, the project received a major boost from lead donors Tina and Hamid Moghadam ’77, SM ’78, allowing the department to break ground in November 2021.

In Moghadam, chair and CEO of Prologis, which owns 1.2 billion square feet of warehouses and other logistics infrastructure worldwide, EAPS found a fellow champion for climate and environmental innovation. By putting solar panels on the roofs of Prologis buildings, the company is now the second largest on-site producer of solar energy in the United States. “I don’t think there needs to be a trade-off between good sound economics and return on investment and solving climate change problems,” Moghadam said at the dedication. “The solutions that really work are the ones that actually make sense in a market economy.”

Architectural firm AW-ARCH designed the Moghadam Building with a light touch, emphasizing spaciousness in contrast to the heavy concrete buildings that surround it. “The kind of delicacy and fragility of the thing is in some ways a depiction of what happens here,” said architect and co-founding partner Alex Anmahian at the dedication reception, giving a nod to the study of the delicate balance of the earth system itself.

Van der Hilst has referred to his vision for the atrium as a “campus living room,” and the furniture throughout is intentionally chosen to allow for impromptu rearrangements, providing a valuable public space on campus for students to work and socialize.

The second level is similarly adaptable, featuring three classrooms with state-of-the-art teaching technologies that can be transformed from a single large space for a hackathon to intimate rooms for discussion.

“The space is really meant for a yet unforeseen experience,” Anmahian says. “The reason it is so open is to allow for any possibility.”

The inviting, dynamic design of the pavilion has also become an instant point of pride for the building’s inhabitants. At the dedication, School of Science dean Nergis Mavalvala quipped that anyone walking into the space “gains two inches in height.”

Van der Hilst quoted a colleague with a similar observation: “Now, when I come into this space, I feel respected by it.”

The perfect complement

Another significant feature of the project is the List Visual Arts Center Percent-for-Art Program installation by conceptual artist Julian Charrière, entitled “Everything Was Forever Until It Was No More.”

Consisting of three interrelated works, the commission includes: “Not All Who Wander Are Lost,” three glacial erratic boulders which sit atop their own core samples in the surrounding green space; “We Are All Astronauts,” a trio of glass pillars containing vintage globes with distinctions between nations, land, and sea removed; and “Pure Waste,” a synthetic diamond embedded in the foundation, created from carbon captured from the air and the breath of researchers who work in the building.

Known for themes that explore the transformation of the natural world over time and humanity’s complex relationship with our environment, Charrière was a perfect fit to complement the new Building 55 — offering a thought-provoking perspective on our current environmental challenges while underscoring the value of the research that happens within its walls.

More than 1,000 Amazon workers warn rapid AI rollout threatens jobs and climate

Workers say the firm’s ‘warp-speed’ approach fuels pressure, layoffs and rising emissionsMore than 1,000 Amazon employees have signed an open letter expressing “serious concerns” about AI development, saying that the company’s “all-costs justified, warp speed” approach to the powerful technology will cause damage to “democracy, to our jobs, and to the earth.”The letter, published on Wednesday, was signed by the Amazon workers anonymously, and comes a month after Amazon announced mass layoff plans as it increases adoption of AI in its operations.

More than 1,000 Amazon employees have signed an open letter expressing “serious concerns” about AI development, saying that the company’s “all-costs justified, warp speed” approach to the powerful technology will cause damage to “democracy, to our jobs, and to the earth.”The letter, published on Wednesday, was signed by the Amazon workers anonymously, and comes a month after Amazon announced mass layoff plans as it increases adoption of AI in its operations.Among the signatories are staffers in a range of positions, including engineers, product managers and warehouse associates.Reflecting broader AI concerns across the industry, the letter was also supported by more than 2,400 workers from companies including Meta, Google, Apple and Microsoft.The letter contains a range of demands for Amazon, concerning its impact on the workplace and the environment. Staffers are calling on the company to power all its data centers with clean energy, make sure its AI-powered products and services do not enable “violence, surveillance and mass deportation”, and form a working group comprised of non-managers “that will have significant ownership over org-level goals and how or if AI should be used in their orgs, how or if AI-related layoffs or headcount freezes are implemented, and how to mitigate or minimize the collateral effects of AI use, such as environmental impact”.The letter was organized by employees affiliated with the advocacy group Amazon Employees for Climate Justice. One worker who was involved in drafting the letter explained that workers were compelled to speak out because of negative experiences with using AI tools in the workplace, as well as broader environmental concerns about the AI boom. The staffers, the employee said, wanted to advocate for a better way to develop, deploy and use the technology.“I signed the letter because of leadership’s increasing emphasis on arbitrary productivity metrics and quotas, using AI as justification to push myself and my colleagues to work longer hours and push out more projects on tighter deadlines,” said a senior software engineer, who has been with the company for over a decade, and requested anonymity due to fear of reprisal.Climate goalsThe letter accuses Amazon of “casting aside its climate goals to build AI”.Like other companies in the generative AI race, Amazon has invested heavily in building new data centers to power new tools – which are more resource intensive and demand high amounts of electricity to operate. The company plans to spend $150bn on data centers in the next 15 years, and just recently said it will invest $15bn to build data centers in northern Indiana and at least $3bn for data centers in Mississippi.The letter claims that Amazon’s annual emissions have “grown roughly 35% since 2019”, despite the company’s promise in 2019 to achieve net zero carbon emissions by 2040. It warns many of Amazon’s investments in AI infrastructure will be in “locations where their energy demands will force utility companies to keep coal plans online or build new gas plants”.“‘AI’ is being used as a magic word that is code for less worker power, hoarding of more resources, and making an uninformed gamble on high energy demand computer chips magically saving us from climate change,” said an Amazon customer researcher, who requested anonymity out of fear of retaliation for speaking out. “If we can build a climate saving AI – that’s awesome! But that’s not what Amazon is spending billions of dollars to develop. They are investing fossil fuel energy draining data centers for AI that is intended to surveil, exploit, and squeeze every extra cent out of customers, communities, and government agencies.”In a statement to the Guardian, Amazon spokesperson Brad Glasser pushed back on employees’ claims and pointed toward the company’s climate goals. “Not only are we the leading data center operator in efficiency, we’re the world’s largest corporate purchaser of renewable energy for five consecutive years with over 600 projects globally,” said Glasser. “We’ve also invested significantly in nuclear energy through existing plants and new SMR technology–these aren’t distractions, they’re concrete actions demonstrating real progress toward our Climate Pledge commitment to reach net-zero carbon across our global operations by 2040.”AI for productivityThe letter also includes strict demands around the role of AI in the Amazon workplace, demands that, staffers say, arose out of challenges employees are experiencing.Three Amazon employees who spoke to the Guardian claimed that the company is pressuring them to use AI tools for productivity, in an effort to increase output. “I’m getting messaging from my direct manager and [from] of all the way up the chain, about how I should be using AI for coding, for writing, for basically all of my day-to-day tasks, and that those will make me more efficient, and also that if I don’t get on board and use them, that I’m going to fall behind, that it’s sort of sink or swim,” said a software engineer who has been with Amazon for over two years, requesting anonymity due to fear of reprisal.The worker added that just weeks ago she was told by her manager that they were “expected to do twice as much work because of AI tools”, and expressed concern that the output expected demanded with fewer people is unsustainable, and “the tools are just not making up that gap.”The customer researcher echoed similar concerns. “I have both personally felt the pressure to use AI in my role, and hear from so many of my colleagues they are under the same pressure …”.“All the while, there’s no discussion about the immediate effects on us as workers – from unprecedented layoffs to unrealistic expectations for output.”The senior software engineer said that the adoption of AI has had imperfect outcomes. He said that most commonly, workers are pressured to adopt agentic code generation tools: “Recently I worked on a project that was just cleaning up after a high-level engineer tried to use AI to generate code to complete a complex project,” said this worker. “But none of it worked and he didn’t understand why – starting from scratch would have actually been easier.”Amazon did not respond to questions about the staffers’ workplace critiques about AI use.Workers emphasized they are not against AI outright, rather they want it to be developed sustainably and with input from the people building and using it. “I see Amazon using AI to justify a power grab over community resources like water and energy, but also over its own workers, who are increasingly subject to surveillance, work speedups, and implicit threats of layoffs,” said the senior software engineer. “There is a culture of fear around openly discussing the drawbacks of AI at work, and one thing the letter is setting out to accomplish is to show our colleagues that many of us feel this way and that another path is possible.”

The passage of long overdue reforms to the Environmental Protection and Biodiversity Conservation (EPBC) Act demonstrates powerfully that democratic governance is alive and well in Australia.The Australian parliament has done its job and passed 21st-century reforms that support a modern economy, enable the creation of new and sustainable jobs while promising not to destroy, but in fact improve, the health of the natural world. This is no small thing. In what are clearly dangerous times for democracies around the world, the Australian parliament has demonstrated emphatically that ambitious economic reform remains possible. And yes, I do mean “economic” reform.As in the past, courageous leadership has been rewarded with agreement. As in the past, the parliament has engaged constructively, in the national interest, rising above the debilitating personality politics and culture wars of recent years.Sign up: AU Breaking News emailThe winners stand to be future generations of Australians. In this instance, our elected representatives have demonstrated they understand that this is where their most weighty obligation is owed. But meeting that obligation is hard. Democracies often appear carefully designed to reward short-termism. Yet the success of a parliament can only be assessed according to what it does for the future. In the final sitting week of 2025, the Australian parliament appears to have delivered.The package of reforms to the EPBC Act fixes an ugly policy mess. The mess had been called out in several reviews, including Graeme Samuel’s review delivered more than five years ago.As I observed in an address to the National Press Club mid-year, report after report tells the same story of failure. The environment is simply not being protected. Biodiversity is not being conserved. Nature is in systemic decline. The environmental impact assessment systems embedded in the laws are simply not fit for purpose. Of particular concern, they are incapable of supporting an economy in transition to net zero.The mess of poorly constructed environmental laws has been undermining productivity. I noted that we simply cannot afford slow, opaque, duplicative and contested environmental planning decisions based on poor information, mired in administrative complexity.This week’s reforms promise to fix the mess.The reformed act will deliver a set of standards that aim to protect matters of national environmental significance. It will provide certainty for all stakeholders about impacts that must be regarded as “unacceptable” and therefore avoided.It builds integrity into the administration of the laws through the establishment of an independent, national EPA. It promises to end the absurd carveout for native forests, the landscapes that remain most richly endowed with biodiversity and healthy ecosystem functioning. And it lays the foundations for the development of regional plans that provide an opportunity for the three levels of government to work with local communities, including First Nations custodians, to design sustainable futures.Significantly, long-overdue protection will be provided for our forests. The lungs of the Earth, a lifeboat against climate change, a filter against sentiment destroying the Great Barrier Reef and a haven for wildlife will be provided real protection, while incentives will be provided to support a modern forestry industry based on plantations.And there is another thing that should be called out at this time. This may be the most important thing.For centuries, humans have believed that economic and social progress necessarily comes at the expense of the environment. We have believed that the destruction of the natural world is a price that must be paid for everything else that matters to us; as we accumulate physical and financial capital, we must run down the stock of natural capital.We have acted as if we can choose, indefinitely, to trade-off environmental integrity for material gains. Our choices have created deserts, waterways incapable of supporting life, soils leached of fertility, climate change driving weather events of such severity and frequency that whole towns, suburbs and agricultural landscapes are fast becoming uninsurable.This week’s amendments acknowledge that the state of the natural world is foundational. That without its rebuilding, future economic and social progress cannot be secured.We should think of economic and social progress as exercises in constrained optimisation. This framing is familiar to those immersed in economic policy. And yet, as I noted in the National Press Club address, economics has for the most part ignored the most important constraints on human choices. These are embedded in the immutable laws of nature. Our failure to recognise that is now undermining productivity growth and having a discernible impact on economic performance. It threatens livelihoods, even lives.Writing into law an acknowledgment that environmental protection and biodiversity conservation necessarily underpin everything else, and that they must therefore have primacy, is a profound achievement. An unprecedented bequest to future generations.

EPA cements delay of Biden-era methane rule for oil and gas

The Trump administration on Wednesday cemented its delay of Biden-era regulations on planet-warming methane coming from the oil and gas industry.

The Trump administration on Wednesday cemented its delay of Biden-era regulations on planet-warming methane coming from the oil and gas industry. Earlier this year, the administration issued an “interim final rule” that pushed back compliance deadlines for the Biden-era climate rule by 18 months. On Wednesday, it announced a final rule that locks in the delay. The delays apply to requirements to install certain technologies meant to reduce emissions. It also applies to timelines for states to create plans for cutting methane emissions from existing oil and gas.  Methane is a gas that is about 28 times as potent as carbon dioxide at heating the planet over a 100-year period. Environmental Protection Agency (EPA) Administrator Lee Zeldin said that the administration was acting in order to protect U.S. energy production.  “The previous administration used oil and gas standards as a weapon to shut down development and manufacturing in the United States,” Zeldin said in a written statement.  “By finalizing compliance extensions, EPA is ensuring unrealistic regulations do not prevent America from unleashing energy dominance,” he added. However, environmental advocates say that the delay will result in more pollution. “The methane standards are already working to reduce pollution, protect people’s health, and prevent the needless waste of American energy. The rule released today means millions of Americans will be exposed to dangerous pollution for another year and a half, for no good reason,” Grace Smith, senior attorney at Environmental Defense Fund, said in a written statement.  Meanwhile, the delay comes as the Trump administration reconsiders the rule altogether, having put it on a hit list of regulations earlier this year.

Analysis-Brazil Environment Minister, Climate Summit Star, Faces Political Struggle at Home

By Manuela AndreoniBELEM, Brazil (Reuters) -Brazilian Environment Minister Marina Silva fought back tears as global diplomats applauded her for...

BELEM, Brazil (Reuters) -Brazilian Environment Minister Marina Silva fought back tears as global diplomats applauded her for several minutes on Saturday in the closing plenary of the COP30 global climate summit."We've made progress, albeit modestly," she told delegates gathered in the Amazon rainforest city of Belem, before raising a fist over her head defiantly. "The courage to confront the climate crisis comes from persistence and collective effort."It was a moment of catharsis for the Brazilian hosts in a tense hall where several nations vented frustration with a deal that failed to mention fossil fuels - even as they cheered more funds for developing nations adapting to climate change.Despite the bittersweet outcome, COP30 capped years of work by the environment minister and President Luiz Inacio Lula da Silva to restore Brazil's leadership on global climate policy, dented by a far-right predecessor who denied climate science.Back in Brasilia, a harsher political reality looms. Congress has been pushing to dismantle much of the country's environmental permitting system. Organized crime in the Amazon is also a problem, and people seeking to clear forest acres have found new ways to infiltrate and thwart groups touting sustainable development.All this poses new threats to Brazil's vast ecosystems, forcing Lula and his minister to wage a rearguard battle to defend the world's largest rainforest. Scientists and policy experts warn that action is needed to discourage deforestation before a changing climate turns the Amazon into a tinderbox. Tensions have been mounting between a conservative Congress and the leftist Lula ahead of next year's general election. Forest land is often at heightened risk during election years.Still, Silva insists Brazil can deliver on its promise to reduce deforestation to zero by 2030.  "If I'm in the eye of the storm," she told Reuters, "I have to survive."Silva, born in 1958 in the Amazonian state of Acre to an impoverished family of rubber tappers, was more rock star than policymaker for many at COP30. Like Lula, she overcame hunger and scant early schooling to achieve global recognition. As his environment minister from 2003 to 2008, she sharply slowed the destruction of her native rainforest.After more than a decade of estrangement from Lula's Workers Party, Silva reunited with him in 2022. Many environmentalists consider her return the most important move on climate policy in Lula's current mandate, which he has cast his agenda as an "ecological transformation" of Brazil's economy.It is a stark contrast from surging deforestation under Lula's right-wing predecessor Jair Bolsonaro, who cheered on mining and ranching in the rainforest.Still, Lula's actual environmental record has been ambiguous, said Juliano Assuncao, executive director of the Climate Policy Institute think tank in Brazil. "What we have at times is an Environment Ministry deeply committed to these issues, but at critical moments it hasn't been able to count on the support of the federal government in the way it should," he said.Lula's government has halved deforestation in the Amazon, making it easier to fine deforesters and choke their access to public credit. New policies have encouraged reforestation and sustainable farming practices, such as cattle tracing.Still, critics say Lula's government has not done enough to stop Congress as it undercut environmental protections and blocked recognition of Indigenous lands. Lawmakers have also attacked a private-sector agreement protecting the Amazon from the advance of soy farming.Lula's environmental critics concede he has limited leverage.When a government agency was slow to license oil exploration off the Amazon coast, the Senate pushed legislation to overhaul environmental permitting. Lula vetoed much of the bill, but lawmakers vowed to restore at least part of it this week. Similar tensions in Lula's last mandate prompted Silva to quit over differences with other cabinet ministers. This time around, Lula has been quick to defend her and vice-versa. During a recent interview in her Brasilia office, Silva suggested that Lula had not changed, but rather that a warming planet has ratcheted up the urgency of climate policy."Reality has changed," she said. "People who are guided by scientific criteria, by common sense, by ethics, have followed that gradual change." HIGHER TEMPERATURES, MORE GUNSEarth's hottest year on record was 2024, fueling massive fires in the Amazon rainforest that for the first time erased more tree cover than chainsaws and bulldozers.Brazilians hoping to preserve the Amazon must struggle against more than just a warmer climate and a skeptical Congress. Organized crime has grown in the region after years of tight funding left fewer federal personnel to fight back, said Jair Schmitt, who oversees enforcement at Brazil's environmental protection agency Ibama. Ibama agents have been caught more often in shootouts with gangs, he added, suggesting more guns than ever in the region. "Rifles weren't this easy to find before," he said.Another challenge: Illegal deforesters have also infiltrated Amazon supply chains touting their sustainability, from biofuels to carbon credits, Reuters has reported. To overcome them, Brazil will need to steel its political will, said Marcio Astrini, the head of Climate Observatory, an advocacy group. Other than that, he added, "we have everything it takes to succeed."(Reporting by Manuela AndreoniEditing by Brad Haynes and David Gregorio)Copyright 2025 Thomson Reuters.
