The Bezos Earth Fund today announced $203.7 million in grants and pledges aimed at advancing climate justice, supporting climate-oriented economic recovery projects and spurring innovation in pathways to decarbonization.

The pledges are part of a 10-year, $10 billion initiative backed by Amazon founder Jeff Bezos to fund scientists, activists, non-governmental organizations and other actors who can address the challenges posed by climate change.

“This funding is just the next step in the Bezos Earth Fund’s commitment to creating catalytic change during this decisive decade,” Andrew Steer, the recently appointed president and CEO of the Bezos Earth Fund, said in a news release. “With each grant, we are helping organizations unblock progress and create pathways to a more sustainable future.”

Today’s announcement covers $73.7 million in immediate donations to 12 organizations, as well as a pledge of another $130 million to be given out by the end of 2021 to organizations supporting the Biden administration’s Justice40 climate initiative. Justice40 is aimed at delivering at least 40% of the overall benefits from federal investments in climate in clean energy to disadvantaged communities.

More than five years after it began, the $20 million NRG COSIA Carbon XPRIZE competition is complete — and for both of the top competitors, converting CO2 into concrete turned out to be the winning strategy.

The carbon conversion contest was launched in 2015 to encourage the development of technologies that turn CO2 into useful products, with the effect of reducing carbon emissions and fighting climate change.

“Flipping CO2 emissions into valuable products is now a proven, successful strategy to build a better world,” XPRIZE CEO Anousheh Ansari said today in a news release announcing the winners.

Concrete is an attractive target for decarbonization because the current production process is said to account for 7% of global CO2 emissions.

SpaceX CEO Elon Musk is putting $100 million into a different kind of “X”: An XPRIZE competition to develop new technologies for sucking carbon dioxide out of Earth’s atmosphere and oceans.

Musk and his foundation will provide the prize money for XPRIZE Carbon Removal, an incentive-based competition that’ll be open to teams around the world.

Teams will be required to create pilot systems capable of removing 1 ton of carbon dioxide per day, and show that their systems can be scaled up economically to the gigaton level.

Reducing CO2 is considered a key requirement for heading off the worst effects of the greenhouse effect and climate change. Total annual emissions of energy-related carbon dioxide currently amount to about 33 gigatons. The long-term goal for the XPRIZE teams should be to contribute to removing 10 gigatons of CO2 per year by 2050.

In today’s news release, Musk said XPRIZE Carbon Removal “is not a theoretical competition.”

“We want to make a truly meaningful impact,” he said. “Carbon negativity, not neutrality. The ultimate goal is scalable carbon extraction that is measured based on the ‘fully considered cost per ton,’ which incudes the environmental impact.”

Billionaires Jeff Bezos and Elon Musk are usually rivals on the final frontier, but they both have a role to play in MethaneSAT, a privately backed satellite mission aimed at monitoring methane emissions.

Last November, the Bezos Earth Fund made a $100 million grant to the Environmental Defense Fund to support the satellite’s completion and launch. That grant was part of a $791 million round that Bezos said was “just the beginning of my $10 billion commitment” to address challenges brought on by climate change.

Now MethaneSAT LLC — a subsidiary of Environmental Defense Fund — is announcing that it’s signed a contract with Musk’s SpaceX to send the satellite into orbit on a Falcon 9 rocket by as early as October 2022.

How billionaires can help win ‘The New Climate War’

If billionaires like Bill Gates and Jeff Bezos really want to maximize their efforts to solve the global climate crisis, they should focus less on gadgetry and more on getting governments to act.

That’s the message from Penn State climatologist Michael E. Mann, who delves into the changing circumstances of a decades-old debate in a book titled “The New Climate War: The Fight to Take Back Our Planet.”

At the age of 55, Mann is a grizzled veteran of climate wars: In 1999, he helped lay out the “hockey stick” projection for rising global temperatures, and in 2009 he was swept up in the Climategate controversy over hacked emails.

Mann has chronicled the conflicts over climate science in a series of books published over the course of the past decade. But in “The New Climate War,” he argues that the terms of engagement have shifted.

Amid waves of wildfires and extreme weather, it’s getting harder to deny that Earth’s climate is becoming more challenging. Instead, the focus of the debate is shifting to whether the climate challenge can be met — and if so, how best to meet it.

Gates has argued that investment in technology is the key to averting a catastrophe. “Tech is the only solution,” he said during last October’s GeekWire Summit. The Microsoft co-founder expands upon that perspective in an upcoming book titled “How to Avoid a Climate Disaster.”

Mann takes issue with that argument in “The New Climate War.”

“Where I disagree with Bill is that, no, I don’t think we need a ‘miracle,’ which is what he said [was needed] to solve this problem,” Mann told me during an interview for the Fiction Science podcast. “The miracle is there when we look up in the sky at the sun, when we feel the wind. … The solutions are there. It’s a matter of committing the resources to scaling them up.”

How to give the climate story a happy ending

Spoiler alert: Kim Stanley Robinson’s latest science-fiction novel about a coming climate catastrophe, “The Ministry for the Future,” doesn’t end with the collapse of civilization.

Millions of people die. Millions more become climate refugees. And the crisis sparks terrorist acts, against those who are working for change as well as against those who are defending the status quo.

But by the end of the book, there’s hope that humanity will actually be able to keep things from spinning out of control. And that’s in line with what Robinson has come to believe in the process of writing “The Ministry for the Future.”

“We could either crash the biosphere, and thus civilization, or we could actually create a really high-functioning and prosperous permaculture, a sustainable and just civilization on the planet in the biosphere,” he says. “Both the utter disaster and the quite great, semi-utopian historical moment are available to us.”

Robinson talks about “The Ministry for the Future,” and the real-world technological initiatives on which his tale is based, in the latest episode of our Fiction Science podcast, which focuses on the intersection of science and fiction.

You can hear the entire 46-minute discussion, moderated by science-fiction author Dominica Phetteplace and myself,  via your favorite podcast channel, whether that’s Anchor, Apple, Spotify, Google,  Breaker, Overcast, Pocket Casts or RadioPublic.

ICESat-2 satellite tracks how polar ice is lost

A satellite mission that bounces laser light off the ice sheets of Antarctica and Greenland has found that hundreds of billions of tons’ worth of ice are being lost every year due to Earth’s changing climate.

Scientists involved in NASA’s ICESat-2 project report in the journal Science that the net loss of ice from those regions has been responsible for 0.55 inches of sea level rise since 2003. That’s slightly less than a third of the total amount of sea level rise observed in the world’s oceans over that time.

To track how the ice sheets are changing, the ICESat-2 team compared the satellite’s laser scans with similar measurements that were taken by the original ICESat spacecraft from 2003 to 2009. (ICESat stands for “Ice, Cloud and Elevation Satellite.”)

“If you watch a glacier or ice sheet for a month, or a year, you’re not going to learn much about what the climate is doing to it,” Ben Smith, a glaciologist at the University of Washington and lead author of the Science paper, said in a NASA news release. “We now have a 16-year span between ICESat and ICESat-2 and can be much more confident that the changes we’re seeing in the ice have to do with the long-term changes in the climate.”

Have we been living in a megadrought?

A comparison of weather records since 2000 with similar time frames in past centuries has led researchers to conclude that we’re in the midst of a megadrought of historic proportions.

The assessment draws upon tree-ring data from nine Western states, stretching from Oregon and Idaho down through California and New Mexico, plus part of northern Mexico. The patterns in the tree rings served to track annual soil moisture going back to the ninth century.

Researchers saw evidence for dozens of droughts across the region over the centuries, but four periods of extreme aridity stood out, in the late 800s, the mid-1100s, the 1200s and the late 1500s. The fourth megadrought, which lasted from 1575 to 1603, was the worst of the bunch.

Since then, there have been no droughts on that scale. Until now.

In this week’s issue of the journal Science, the research team reports that the 19-year period beginning in the year 2000 has been almost as dry as the worst 19-year period of the 1575-1603 megadrought, based on soil moisture readings.

Amazon CEO Jeff Bezos says he’s launching a $10 billion Bezos Earth Fund that will issue grants aimed at addressing climate change — a move that comes less than a month after hundreds of Amazon employees criticized what they saw as the company’s weak commitment to tackling the issue.

Bezos, who’s the world’s richest individual with a net worth estimated at nearly $130 billion, unveiled his philanthropic initiative in an Instagram post.

“Climate change is the biggest threat to our planet,” he wrote. “I want to work alongside others both to amplify known ways and to explore new ways of fighting the devastating impact of climate change on this planet we all share.”

He said the first grants to scientists, activists and non-governmental organizations would be issued this summer.
