Fossa (Cryptoprocta ferox) at the Houston Zoo.
The fossa, Madagascar's largest predator, is a cat-like carnivore that eats everything from insects to lemurs. Because they are rare and elusive, scientists know very little about them, including how many there are.
Environmental regulations generally improve communities’ preparedness and resilience during disasters.

The damage to coal ash sites from Hurricane Florence demonstrates how a community's vulnerability to natural disasters is closely linked to how stringent environmental regulations are.

Lessons learned from Hurricane Andrew in 1992 and the Fukushima disaster in 2011 have changed how utilities brace for big storms.
A study finds that higher ozone levels correlate with slower performance times for college endurance athletes.
US ozone pollution has fallen in recent decades, but exposure to low levels of ozone still has serious effects on human health and well-being.
Buildings damaged by Hurricane Maria are seen in Lares, Puerto Rico, October 2017.
Thousands died after Hurricane Maria, but it did not have to be that way. Early evidence should have led the government to a much stronger response.

Many factors can influence people to evacuate or stay in place when disasters loom. Research using Facebook posts suggests that people with broad social networks are more apt to get moving.

Hurricanes in the southern US have caused widespread damage inland in recent decades, mainly through river flooding. But evacuations and stormproofing focus almost entirely on keeping people safe on the coasts.

Wetlands are some of the world's most undervalued weapons against climate change. They store huge quantities of carbon – but without better protection, many could soon be drained or paved over.

Weather towers like this one in a park in Vienna were a popular way for the 19th-century public to track the influence of weather on their lives.
Climate science in the computer age is the pursuit of elite scientists. A historian of science sees an upside to the popular, participatory approach of studying changes to the climate from the 19th century.
Divestment rally at Harvard University, April 17, 2015.
Many students and professors at US colleges and universities want their schools to divest holdings in fossil fuel companies, but it's a hard sell for school administrators.

Taking this step may improve the quality of life for vulnerable people and reduce the amount of air conditioning they use, making their neighborhoods less prone to power outages.

Taking millions of gallons of water permanently out of the Colorado River amid a prolonged drought would surely start an interstate fight.
The 2016 Maple fire (photographed in July 2017) reburned young forests that had regenerated after the 1988 Yellowstone fires. More frequent high-severity fires are expected in the future as climate warms, which may change patterns of forest recovery.
Huge fires roared through Yellowstone National Park in the summer of 1988, scorching one-third of the park. Since then the park has been a valuable lab for studying how forests recover from fires.

Many US coastal towns are building defenses to protect against rising seas and storms. This can encourage people to stay in place when they should be moving inland.
