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 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.
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.
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.
Natural gas was once widely seen as a bridge fuel to renewable energy. But the industry’s methane leaks make it a larger global warming threat than people realized.

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.
About 60% of Mexico’s forests are managed by local communities. A scholar who has studied the forests for 30 years explains how this system protects the forests and the people who oversee them.
A closer look at how ice cover changed through the months offers some important insights into the role of climate change and why every year isn’t a record.
It’s the World Health Organization’s first update of global air quality guidelines since 2005. We know far more today about the serious risks these pollutants pose to human health.
Bats roost under bridges and culverts across North America, so highway departments have to check for them before repairing bridges. A new AI tool makes those inspections faster and more accurate.
A growing number of countries and companies have pledged to reach net-zero emissions by 2050 or earlier. But there’s a catch – they still plan to keep emitting greenhouse gases.
Through its Belt and Road Initiative, China has become the world’s largest country-to-country lender. A new study shows that more than half of its loans threaten sensitive lands or Indigenous people.
As the state copes with hurricanes and climate disasters, it is figuring out how to manage the slow-motion loss of its coastal land. But its plans could endanger the cultures that define the region.
Rivers are among the most embattled ecosystems on Earth. Researchers are testing a new, inexpensive way to study river health by using eDNA to count the species that rivers harbor.
Energy and climate policies aren’t always headed in the same direction, but if they work together they can tackle two of the biggest challenges of our time.
Pew asked people in 17 countries how they felt about climate change. The survey found some optimism but also deep ideological divides, particularly in the United States.

A new study provides a detailed way to calculate the climate impact of food production, which could lead to more sustainable farming policies and methods.
A decade ago, solar power was a tiny sliver of the US energy supply. Today it’s expanding rapidly – and the Biden administration wants to make it much, much bigger.
