Health boost from nature

Trees lining a street may encourage people to take a longer stroll or choose to bike to work. New research shows how access to natural areas in cities can improve human health by supporting physical activity. The researchers plan to equip city planners with tools to create healthier, more sustainable cities around the world.

Biodiversity loss in warming oceans

A fossil study from Stanford University finds the diversity of life in the world’s oceans declined time and again over the past 145 million years during periods of extreme warming. Temperatures that make it hard for cold-blooded sea creatures to breathe have likely been among the biggest drivers for shifts in the distribution of marine biodiversity.

Climate change-resilient infrastructure

In his address to Congress tonight, President Joe Biden is expected to pitch a wide-ranging initiative called the American Jobs Plan. Stanford researchers discuss how and why climate change resilience is central to the initiative.

Flood risk’s impact on home values

Analysis of sales data and flood risk data over two decades indicates that housing markets fail to fully account for information about flood risk. The findings suggest that policies to improve risk communication could influence market outcomes.

AI empowers environmental regulators

Monitoring environmental compliance is a particular challenge for governments in poor countries. A new machine learning approach that uses satellite imagery to pinpoint highly polluting brick kilns in Bangladesh could provide a low-cost solution.

Illuminating a sea turtle mystery

North Pacific loggerhead turtles’ years-long oceanic journeys remain poorly understood. Using data from satellite tracking and other techniques, scientists reveal a unique phenomenon that may explain the endangered migrants’ pathway.

Jordan’s worsening water crisis a warning for the world

Prolonged and potentially destabilizing water shortages will become commonplace in Jordan by 2100, new research finds, unless the nation implements comprehensive reform, from fixing leaky pipes to desalinating seawater. Jordan’s water crisis is emblematic of challenges looming around the world as a result of climate change and rapid population growth.
