Air pollution is often discussed at national or global scales, annual averages, country rankings, and international targets. But the air people actually breathe is shaped much closer to home: by traffic corridors, fuel choices, land use patterns, and industrial activity unfolding block by block within cities.  To understand how air quality science becomes actionable at […]

When we talk about climate solutions, we often picture sweeping policy changes, massive clean-up operations, or complex new technologies. Rarely do we think about the objects we interact with every day, the small, forgettable items we replace without much thought.  An umbrella is one of them.  But for Deirdre Bird, founder and CEO of Dri

Six months is not a long time in the health tech industry.  It’s not enough time to solve air pollution, rebuild cities, or undo decades of environmental harm. But in a startup, six months can be transformative. It can be the difference between an idea and an engine, between early traction and real momentum.  When

When I first began exploring the world of air quality and climate technology, I envisioned it as a field primarily driven by scientists and researchers. However, the more conversations I had, from global conferences to interviews across continents, the more I realized that climate solutions emerge from every corner of society, including policymakers, engineers, activists,

In the last blog, we mapped the landscape of air data, exploring its origins, collection methods, and the significance of each source. But measurement is only the beginning. Data becomes meaningful when it informs decisions, drives accountability, and ultimately, shapes the air we breathe. This is the story of how air data becomes policy, and

We breathe over 10 kilograms of air every single day, far more than the food and water we consume (Pleil et al., 2021). And yet, air is invisible, intangible, and often taken for granted until it makes us cough, wheeze, or stay inside due to smoke. But the air we breathe is a personal experience

In my previous post, “Pollution Without Borders: What Atmospheric Science Teaches Us About Global Connections,” I introduced readers to Dr. Jim McQuaid, an atmospheric scientist whose career has taken him from the Sahara Desert to Indonesian peatlands, always chasing gases and particles, and processes that tie our air together. I recommend starting there for a

The green economy is more than solar panels, wind farms, and clean tech. It’s also about who leads, who benefits, and whose voices shape the transition. Around the world, particularly across Africa, women are on the front line of climate change. They are often the first to feel its burdens, from energy poverty to food

Air pollution doesn’t stop at borders. A wildfire burning in Canada can send smoke curling across the Atlantic, producing great sunsets in London. Storms born in the Sahara Desert can drift across the Atlantic Ocean and become hurricanes that eventually crash into the U.S. Gulf Coast. Local pollution events have global consequences, often in ways

From predicting wildfires to mapping urban heat islands, the fusion of AI and geospatial data is reshaping how we understand and respond to climate change. Behind these innovations are people like Ryan Kmetz, who are redefining what’s possible when technology meets environmental science. When Ryan Kmetz reflects on his career, the central thread is his
