Published to coincide with the launch of NASA’s Perseverance rover mission this summer, the definitive account of our quest to find life on the Red Planet. From The War of the Worlds to The Martian and to the amazing photographs sent back by the robotic rovers Curiosity and Opportunity, Mars has excited our imaginations as the most likely other habitat for life in the solar system. Now the Red Planet is coming under scrutiny as never before. As new missions are scheduled to launch this year from the United States and China, and with the European Space Agency's ExoMars mission now scheduled for 2022, this book recounts in full the greatest scientific detective story ever.   For the first time in forty years, the missions heading to Mars will look for signs of ancient life on the world next door. It is the latest chapter in an age‑old quest that encompasses myth, false starts, red herrings, and bizarre coincidences—as well as triumphs and heartbreaking failures. This book, by two journalists with deep experience covering space exploration, is the definitive story of how life's discovery has eluded us to date, and how it will be found somewhere and sometime this century. The Search for Life on Mars is based on more than a hundred interviews with experts at NASA’s Jet Propulsion Laboratory and elsewhere, who share their insights and stories. While it looks back to the early Mars missions such as Viking 1 and 2 , the book's focus is on the experiments and revelations from the most recent ones—including Curiosity, which continues to explore potentially habitable sites where water was once present, and the Mars Insight lander, which has recorded more than 450 marsquakes since its deployment in late 2018—as well as on the Perseverance and ExoMars rover missions ahead. And the book looks forward to the newest, most exciting frontier of all: the day, not too far away, when humans will land, make the Red Planet their home, and look for life directly.

What exactly is ‘sustainable’ about Amazon’s new jet fuel?

Amazon’s fleet of aircraft, which is soon to surpass 80 Boeings, enables the e-commerce giant to deliver everything from dog food to Dysons within two days. It’s an impressive logistical feat, but it comes with a heavy carbon footprint — and is particularly conspicuous given the company’s recent pledge to achieve net-zero emissions by 2040. To start to address the issue, Amazon Air announced on Wednesday that it will buy up to 6 million gallons of sustainable aviation fuel, which it says will reduce its aircrafts’ emissions by 20 percent.

While the purchase is a small step that won’t substantially reduce the company’s overall carbon footprint, it may help boost demand for alternative fuels, which are currently too expensive to be competitive with conventional jet fuel.

What makes sustainable aviation fuel (SAF) “sustainable” is not necessarily that it produces fewer carbon emissions than conventional jet fuel when it’s burned in an airplane — it’s that it has a smaller carbon footprint when the entire life cycle of the fuel is taken into account. (In addition, many SAFs burn more cleanly, spewing less soot and other pollutants from a plane’s engine.)

SAFs can be made from a number materials, like various plant oils and crops like poplar and switchgrass. Many of the SAFs under development are made from reusable waste products, like used cooking oil, animal fat, municipal solid waste, and corn leaves, stalks, and cobs. Amazon plans to use a blend of jet fuel and SAF derived from animal fats and oils, produced by the fuel company World Energy.

To assess the emissions reductions claimed by Amazon’s SAF, you need to assess every step of its life cycle, compared to that of conventional jet fuel. Jet fuel starts as crude oil in the ground. It has to be pumped, shipped, or sent via pipeline to a refinery, where it is refined and then shipped again to the airport before it’s burned in an engine. The process for Amazon’s SAF, on the other hand, involves growing and delivering food for livestock, feeding and processing the animals, delivering the fat to a refiner and refining it, getting the fuel to the airport, and burning it in the plane. By saying that this fuel will reduce emissions by 20 percent, Amazon and World Energy are essentially claiming that this whole chain of events generates 20 percent fewer emissions than the one for the crude oil the company would have used instead.

Annie Petsonk, international affairs counsel for the Environmental Defense Fund, called Amazon’s purchase an “important baby step” because it could boost demand for sustainable fuels. Today, SAFs are deep in the “valley of death” that frustrates many new energy technologies, she said. Sustainable fuels tend to be more expensive than conventional jet fuel, and investors don’t want to support the innovations that could bring prices down until there’s a bigger market. Some state and federal incentives exist to lower the price, but they still don’t make the price of SAFs competitive with conventional jet fuel, which is especially cheap at present due to the economic slowdown caused by the COVID-19 pandemic.

Petsonk said Amazon’s purchase will help demonstrate that SAFs work and that major companies are willing to pay a premium for them. Her team calculated that switching from conventional jet fuel to the new fuel could reduce the company’s emissions by about 12,000 metric tonnes of CO2. (Achieving this reduction could be jeopardized if production of the fuel has indirect climate impacts, such as causing other companies that use animal fat to switch to palm oil, thereby contributing to deforestation.)

Given that Amazon’s 2019 self-reported carbon footprint was more than 50 million metric tonnes, a 12,000 metric tonne reduction is a drop in the bucket. But at this point, the options to reduce aviation-related emissions are still relatively limited. There are other SAFs that boast larger carbon reductions, but they are still in the early stages of development. The Illinois-based biotech startup LanzaTech is one of the leaders in the space. It produces a form of sustainable ethanol for jet fuel by capturing the emissions from steel mills. Another company, Velocys, is building a plant in the U.K. to supply British Airways with jet fuel made from household waste that would otherwise go to a landfill. Both companies boast a 70 percent reduction in greenhouse gases compared to conventional jet fuel.

Right now SAFs make up just a fraction of a percent of the fuels burned in airplanes, Petsonk said. But with governments around the world excusing the industry from its emissions reduction goals, Amazon’s adoption of sustainable fuel does move the needle, however slightly.

The BREATHE Act would defund police — and fund environmental justice

As the U.S. enters another month of sustained protests against anti-Black racism and police brutality, organizers are working to turn the protests’ energy into legislative action. This week the Movement for Black Lives, a nationwide coalition of Black organizations formed in December 2014, released a summary of a new legislative proposal that aims to defund police police forces around the country and give funding and support to Black communities looking to create their own models of public safety. They’re calling it the BREATHE Act.

“We crafted this bill to be big,” said Gina Clayton Johnson, the executive director of Essie Justice Group and one of the act’s creators, during a virtual announcement event reported by New York Magazine’s The Cut. “We know the solution has to be as big as the 400-year-old problem itself.”

The proposal is divided into four sections that each address different approaches to sustainable public safety: The first two sections call for the divestment of federal resources from policing and incarceration, as well as federal grant programs for alternative community-led approaches to non-punitive public safety.

The proposal’s third section, however, demonstrates that environmental justice is central to the proposal’s vision. It calls for the creation of a grant that will fund solutions for environmental justice issues that affect Black communities around the country. The grant would fund “clear, time-bound plans” for states to ensure universal access to clean water and air that satisfies Environmental Protection Agency guidelines. The section also calls for for the creation of clear state plans to meet 100 percent of their electricity demand with “clean, renewable, and zero-emission energy sources.” Funding for community-owned sustainable energy projects would be subsidized by the grant. Disaster preparedness would also be prioritized.

Environmental justice often intersects with other public health issues for Black and brown communities. In recent months, for example, it’s become clear that Black and Latino communities in the U.S. suffer higher mortality and hospitalization rates from the novel coronavirus. This May, Democrats in Congress introduced the Environmental Justice COVID-19 Act to look at the connection between air pollution and disproportionate COVID-19 outcomes for these communities.

The BREATHE Act has not yet been translated into actionable congressional legislation, but Democratic Representatives Rashida Tlaib and Ayanna Pressley both expressed their support for the proposal during a virtual meeting this week.

“The BREATHE Act is bold…. It pushes us to reimagine power structures and what community investment really looks like,” Tlaib said during a recent call with activists. “We can start to envision through this bill a new vision for public safety. One that protects and affirms Black lives.”

The climate fix you’ve been waiting for: Rock dust?

Scientists have been trying to figure out how to make use of one of nature’s tricks for removing carbon dioxide from the atmosphere with rock and rain. As rain washes away tiny particles of rock, newly exposed minerals bind with carbon, transforming carbon dioxide into new chemicals. It’s a simple combination of basic chemistry and erosion.

We can speed the process up by speeding up erosion, crushing tons and tons of rock and spreading it across the earth’s surface, if we had the money to do it and a vast area where inhabitants don’t mind trucks covering everything with a layer of rock dust once a year. Farms are the most likely candidate for such a massive undertaking, because farmers already do some incidental advanced weathering as a byproduct of “liming”, where they apply crushed limestone to fields when their soils become too acidic.

A paper just published in Nature provides the most detailed calculation to date of just how much carbon this technique, known as enhanced weathering, could capture and how much it would cost. Deploying the practice worldwide could remove 2 billion tons of carbon dioxide from the air every year — about a third of what the United States emits each year — and would run between $60 and $200 per ton of carbon to apply all that rock dust on fields, varying by country. It would be cheaper in places like Indonesia and India that have better conditions for weathering (warm, seasonally wet weather), and low labor and energy costs. The countries with the greatest potential to deploy enhanced weathering are, the researchers note, “coincidentally the highest CO2 fossil fuel emitters (China, USA, and India).”

One of the scientists involved in the study, James Hanson, the climate Cassandra and Columbia University climatologist, said in an email that he became interested in weathering because it can trap carbon for thousands of years. Hansen said other approaches, “such as reforestation, are important, but require management to assure that the carbon sink is maintained.”

The researchers estimate that if the United States spread rock dust on half the country’s farmland it could capture 420 million tons of carbon dioxide, at an annual cost of $225 for every American, or $176 for every ton of carbon. That’s a higher price tag than some other solutions. Building solar farms, for instance, currently cuts emissions at a rate of less than $40 per ton. But because the world is failing to slash emissions, the Intergovernmental Panel on Climate Change has determined that we will need to use “negative emissions,” expensive techniques to suck carbon out of the atmosphere, to avoid the most dangerous consequences of climate change.

Farmers stand to benefit, too. In theory, spreading much more rock dust on fields could improve soil health and crop yields. And that could help farmers get out of poverty and increase world food production at the same time they’re soaking up carbon. And, as with any major attempt at geoengineering our atmosphere, there’s likely to unforeseen pitfalls, and unexpected benefits, along the way.

The plan meant to unite Biden and Bernie voters on climate is finally here

Once upon a time, many moons ago — i.e., back in April — Democratic presidential primary candidate Bernie Sanders agreed to exit the race and join forces with his mortal frenemy Joe Biden to help the former vice president take the White House. The two announced they were putting together a series of joint “unity” task forces with experts from each of their camps to shape the Democratic platform, including a task force on climate change.

After a few months of weekly Zoom meetings and conference calls, the task forces sent their final recommendations to the Democratic National Committee for its consideration on Wednesday.

On climate change, the two candidates and their supporters had some serious divides to bridge. Over the course of nine months of primary debates, Biden touted his plan to build 500,000 electric vehicle chargers and put his faith in American exceptionalism while Sanders bashed fossil fuel executives and promoted the Green New Deal. To try to find a middle ground, Sanders appointed Representative Alexandria Ocasio-Cortez, Sunrise Movement co-founder Varshini Prakash, and Catherine Flowers, the founder of the Center for Rural Enterprise and Environmental Justice, to the joint climate task force. Biden selected former Secretary of State John Kerry, former Environmental Protection Agency administrator Gina McCarthy, and former Biden policy advisor Kerry Duggan, along with two members of Congress.

From the preamble to the task force’s policy recommendations, it’s clear that Sanders’ camp had a meaningful influence on the platform. Titled “Combating the climate crisis and pursuing environmental justice,” the introduction immediately namechecks communities that have suffered the most from the effects of climate change, like Houston, Texas and Paradise, California, and quickly moves on to those that have long suffered from racist policies and pollution, like Flint, Michigan and the Navajo Nation. The platform goes on to work justice and equity into pretty much every bullet point, from eliminating legacy pollution like Superfund sites, to creating union jobs in clean energy that reflect the full diversity of the country. While the Green New Deal is never mentioned, traces of it are all over the place.

Prakash wrote about her experience on the task force on Twitter on Wednesday, explaining that she had two goals: to push Biden to increase his ambition on climate change in terms of timelines and benchmarks, and to place environmental and climate justice at the heart of all of Biden’s climate policies.

On Prakash’s first goal, there was certainly some success. Previously, Biden’s climate policies centered around achieving 100 percent clean electricity by 2050. The task force shaved 15 years off that goal. It also came up with a slew of closer, more specific benchmarks: Within five years, make all school buses electric and help spur retrofits of 4 million buildings by unlocking private sector funding and setting efficiency standards, and by 2030, zero out the carbon footprint of all new buildings.

As for Prakash’s second goal, she applauded Biden’s commitment to putting environmental justice at the heart of his climate policy agenda by “directing federal funds to disadvantaged communities, ending pollution & toxic waste sites, and creating mitigation strategies and rebuilding from disaster in just and equitable ways.”

“We are leaving these discussions with policies that, if implemented, will make Joe Biden’s climate agenda far more powerful, equitable, and urgent than where his plans were just weeks ago,” she tweeted.

Naturally, there is evidence of compromise throughout the task force’s plan. While the document endorses repealing fossil fuel subsidies and addressing methane emissions from oil and gas infrastructure, it does not say anything about fracking, and the only pipeline that it mentions is the “diverse pipeline of talent” the government should help create to fill good clean energy jobs. However, it does urge the Democratic party to explicitly fess up to “historic wrongs” perpetrated against Native American tribes with respect to infrastructure (i.e. pipelines), and to commit to a more robust and meaningful consultation process with tribes across all federal agencies. To do so, the task force recommends conducting a “Tribal Needs Assessment” to understand how to support more than 500 tribes in the energy transition.

Primary season left the Democratic party deeply divided, and some on the climate left will inevitably remain skeptical that a Biden administration will be ambitious enough. This document is by no means the scripture of climate policy. But Biden has proven to be pliant, allowing himself to be pushed further and further on climate since first announcing his candidacy, and this experiment in intra-party negotiation and compromise offers some evidence that the trend could continue.

The researcher who discovered the Great Pacific Garbage Patch—and remains one of today's key advocates for plastic pollution awareness—inspires a fundamental rethinking of the modern Plastic Age.  In 1997, environmentalist Charles Moore discovered the world's largest collection of floating trash—the Great Pacific Garbage Patch ("GPGP")—while sailing from Hawaii to California. Moore was shocked by the level of pollution that he saw. And in the last 20 years, it's only gotten worse—a 2018 study has found that the vast dump of plastic waste swirling in the Pacific Ocean is now bigger than France, Germany, and Spain combined—far larger than previously feared. In  Plastic Ocean , Moore recounts his ominous findings and unveils the secret life of plastics. From milk jugs and abandoned fishing gear to polymer molecules small enough to penetrate human skin and be unknowingly inhaled, plastic is now suspected of contributing to a host of ailments, including infertility, autism, thyroid dysfunction, and certain cancers. An urgent call to action,  Plastic Ocean's  sobering revalations have been embraced by activists, concerned parents, and anyone alarmed by the deadly impact and implications of this man-made environmental catastrophe.

A Silent Spring for oceans, written by "the Rachel Carson of the fish world" ( The New York Times ) Who can forget the sense of wonder with which they discovered the creatures of the deep? In this vibrant hymn to the sea, Callum Roberts—one of the world’s foremost conservation biologists—leads readers on a fascinating tour of mankind’s relationship to the sea, from the earliest traces of water on earth to the oceans as we know them today. In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life. We have always been fish eaters, from the dawn of civilization, but in the last twenty years we have transformed the oceans beyond recognition. Putting our exploitation of the seas into historical context, Roberts offers a devastating account of the impact of modern fishing techniques, pollution, and climate change, and reveals what it would take to steer the right course while there is still time. Like Four Fish and The Omnivore’s Dilemma , The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.
