California's Sierra snowpack peaked at only 73% of average on February 25, 2026, and has since diminished. The Northern Sierra recorded just 10% of normal snow levels by mid-April.

The near-record temperatures are expected to last into this weekend, forecasters say. While it's not unprecedented to see high temperatures climb toward 90F on an April day, the length of such an April heatwave is rarely seen.

Architecture can no longer be conceived as an isolated object, detached from the technical networks that sustain contemporary life. This condition calls for new readings and approaches.

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.

Project PLATEAU, led by Japan's Ministry of Land, Infrastructure, Transport and Tourism, aims to develop and expand access to 3D models representing the diversity of cities across the country, enhancing urban resilience and addressing local challenges.

In North Oaks, Minnesota, property lines extend to the middle of the street, which means the entire city is considered private property.

When scientists applied a new model of human survivability that takes into account the body's ability to function and stay cool depending on age, they found all six events had seen non-survivable periods for older people who could not find shade.

Google tasked Gemini with sorting through 5 million news articles from around the world and isolating flood reports. It transformed this data into a geo-tagged series of chronological events. Next, researchers trained a model to ingest current weather forecasts and leverage the Groundsource data to determine the likelihood of a flash flood in a given area.

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.

"So whenever people think about hot weather, they always talk about the temperature," he says. "There's two issues with that. First of all, most people don't realise that the temperature is measured in the shade. So if you're in direct solar radiation, the amount of heat stress you're exposed to is much greater as it will stress your body out a lot more."

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.

This past week in New York City, fifteen inches of snow fell and more than twenty-two hundred snowplows pushed it away. Twelve thousand miles of sidewalk were shovelled. Two hundred and nine million pounds of salt were spread, and, after it got really bad, two hundred thousand gallons of calcium chloride, a chemical ice melt, were deployed. Sometimes the work you do leaves its mark; sometimes it doesn't.

They were trying to get to the bottom of how to diminish catalogue distribution without having a negative impact on store and online sales. They were also keen to define the geographic areas where digital content would work best and how to profile those areas to classify digital purchase behaviour. Together with Analytic Partners they were able to uncover opportunities to eliminate 22% of catalogues with negligible sales impact and increasing digital support in high-performing topologies, preserving€ 294 million in sales.

Because the past three years have shattered temperature records, researchers have been exploring whether global warming is accelerating, and if so, why. Many scientists agree that the rate at which it is increasing has picked up. This is mainly because of a reduction in air pollution following the introduction of fuel regulations for international shipping (which has resulted in fewer pollutant particles that reflect sunlight into space and seed insulating clouds).

While the data shows 80% of people live within walking distance of green or blue spaces such as a river, park or woodland, it also reveals a disparity between rural and poorer urban areas. In some areas of local authorities, fewer than 20% of residents live close to these spaces, according to data released by the Department for Environment, Food and Rural Affairs on Wednesday.
