Evacuations ordered as a powerful storm heads for California’s wildfire burn scars, raising risk of mudslides – this is what cascading climate disasters look like

Studies show climate change is raising the risk of cascading hazards that alone might not be extreme but add up to human disasters. Communities and government agencies aren’t prepared.

Cities worldwide aren’t adapting to climate change quickly enough

More than half of the world’s population lives in cities, and that share is growing. Rapid climate change could make many cities unlivable in the coming decades without major investments to adapt.

Infrastructure bill passed by Congress promises billions for bridge repair – rural Alaska shows the growing need as temperatures rise

Alaska is warming faster than any other U.S. state, and that’s causing problems, a team of bridge engineers and social scientists explains. The infrastructure bill in Congress would offer some help.

Ancient groundwater: Why the water you’re drinking may be thousands of years old

As surface water diminishes in the Western US, people are drilling deeper wells – and tapping into older groundwater that can take thousands of years to replenish naturally.

Winners of 2021 Nobel Prize in Physics built mathematics of climate modeling, making predictions of global warming and modern weather forecasting possible

Modern climate and weather models can predict what the weather will be next week and what the climate may be in 100 years. They would not exist without Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi.

Dangerous urban heat exposure has tripled since the 1980s, with the poor most at risk

Hot, humid population centers are becoming epicenters of heat risk as climate changes worsens. It’s calling into question the conventional wisdom that urbanization uniformly reduces poverty.

Puerto Rico has a once-in-a-lifetime chance to build a clean energy grid – but FEMA plans to spend $9.4 billion on fossil fuel infrastructure instead

Four years after Hurricane Maria wreaked havoc on Puerto Rico, federal money to rebuild its electricity system is finally about to flow. But it may not deliver what islanders want.

Five years after largest marine heatwave on record hit northern California coast, many warm–water species have stuck around

The Blob, a long-lasting mass of warm water, sat off the Pacific coast of North America for years, bringing new species to formerly cold waters. What allows some to survive while others fade away?

Monsoons make deserts bloom in the US Southwest, but climate change is making these summer rainfalls more extreme and erratic

Monsoons are weather patterns that bring thunderstorms and heavy rains to hot, dry areas when warm, moist ocean air moves inland. They’re challenging to forecast, especially in a changing climate.

Who pays and who benefits from a massive expansion of solar power?

President Biden’s proposed solar power expansion would cost $350 billion in federal support over the coming decade. An energy expert explains where that money would come from and who it would help.

Avoiding water bankruptcy in the drought-troubled Southwest: What the US and Iran can learn from each other

Cities and farmers in the Southwest are resorting to unsustainable strategies to pull in more water. Iran has tried many of these strategies and shows how they can go wrong.

Big fires demand a big response: How 1910’s Big Burn can help us think smarter about fighting wildfires and living with fire

The US has learned that it cannot suppress its way to a healthy relationship with fire in the West. That strategy failed, even before climate change proved it to be no strategy at all.
