We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.
The first step to sustainability is seeing that there is no boundary between you and nature. When we see this essential connection and reverse the artificial disconnections created over millennia, people can imagine a future where we all thrive with a regenerated ecosystem.
Citizen Science Month is built around a goal of 2.5 million 'Acts of Science,' tying the annual event to America's 250th birthday through a simple but powerful idea: lots of small contributions can add up to something really meaningful.
In the past, roof inspections mostly focused on what could be seen from the outside. Contractors looked for broken shingles, worn flashing, or areas where water might enter the roof. The problem is that roof damage does not always show clear signs right away. Water can move through roofing layers before it becomes visible inside the home.
While humans have assembled a lot of weather data, flash floods are too short-lived and localized to be measured comprehensively, the way the temperature or even river flows are monitored over time. That data gap means that deep learning models, which are increasingly capable of forecasting the weather, aren't able to predict flash floods.
Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.
It can drive through the field and look at every square inch. We really honed our craft on model performance and detection with rocks, and now we've transitioned that into weeds. The robot uses a boom-mounted camera system to capture detailed imagery across the field. With eight cameras operating at 1 millimetre resolution, TerraScout can generate billions of data points per acre, allowing it to identify specific objects, including individual weeds.
The input planning calculator is a robust tool that can help farmers and agronomists better understand on-farm finances while helping uncover which crops make the most sense to plant from a cost perspective. By inputting key on-farm financial and agronomic data, including seed and agronomy service costs, growers can compare each crop on their farm and explore their true cost of production.
Both species are under threat. But while African savanna elephants are endangered, forest elephants are critically endangered. They're also highly elusive. Living in dense tropical rainforests in central Africa and parts of West Africa they're very hard to find and study.
To capture the biological impact of this extreme environment, I used a comprehensive suite of sensors and biomarker analyses. I wore a wireless electroencephalograph (EEG) system to monitor brain activity, sleep stages and neural signatures of stress and adaptation; the Oura Ring to continuously track sleep patterns, heart-rate variability and circadian-rhythm shifts; and the glucose monitor to follow metabolic responses in real time.
You can go onto your cloud account either through the iPad or your desktop computer and pre-plan all your jobs... when your hired man goes into the field he can just pick the job... and then hit start and you can go.
It has been an eventful few months for the Northern Hemisphere atmosphere. An unusually early sudden stratospheric warming episode in late November appears to have factored into a weakened and distorted polar vortex at times in December, likely causing extra waviness in the polar jet stream. This helped fuel extensive intrusions of frigid air into the mid-latitudes, contributing to cold snaps in North America, Europe, and Asia, and priming the atmosphere for disruptive winter storms in January.
By the end of the year, Northwood, based in El Segundo, California, had shown the ability to build eight of these Portal arrays a month. And in January the company had deployed operational Portal antennas across two continents. These deployments, which comprise an area of 8 to 15 meters, have the equivalent capability of a 7-meter parabolic dish, said Griffin Cleverly, co-founder and chief technical officer of Northwood.
In this photo, I'm preparing drifting buoys for deployment. This was my main responsibility aboard the RV Falkor (too), during a 27-day research expedition in October 2025 exploring the Malvinas Current, an ocean current that runs alongside Argentina. The expedition included biologists, geologists and physical oceanographers such as myself; I'm a PhD candidate at the Sea and Atmosphere Research Center (CIMA) in Buenos Aires, Argentina.
Yaghi describes AI not as a silver bullet, but as an advanced form of statistical pattern recognition-tools that can identify trends in data that may be difficult or time-consuming for people to uncover on their own. The real opportunity, he says, depends heavily on what farms are already doing. Operations that are consistently collecting and digitizing high-quality data are better positioned to benefit, whether the goal is lowering per-cow costs in a dairy, improving financial analysis, or identifying operational efficiencies.
Wildfire prevention has traditionally relied on blunt tools, such as rigid inspection cycles and emergency power shutoffs. Now a new generation of technology start-ups is pitching a more targeted approach: using artificial intelligence to help utility companies decide what to inspectand where to intervenebefore a spark becomes a blaze. The stakes are rising. In 2025 more than 77,000 wildfires were reported in the U.S.significantly more than the past decade's averageand burned more than five million acres.
