When Kirsten Delegard's grandparents bought their first house in south Minneapolis in 1941, they signed the property's deed, as is standard for any homebuyer.

But the deed came with this line: "No person or persons other than of the Caucasian race shall be permitted to occupy said premises or any part thereof."

With the coronavirus pandemic eroding state budgets across the country, many communities risk having this disaster make them less prepared for looming climate-driven disasters.

Still recovering from devastating wildfires, California was poised to spend billions of dollars to prepare for future fires and other extreme weather disasters. The infrastructure projects, designed to make communities and homes more resistant to wildfire, have long been overlooked, fire experts say.

But with a $54 billion budget deficit, the programs are being put on hold.

As the climate has warmed, Antarctica and Greenland have lost enough ice in the last 16 years to fill Lake Michigan, according to results from a new NASA mission.

Put another way, more than 5,000 gigatons of ice has melted (a gigaton equals one billion metric tons or enough to fill 400,000 Olympic-sized swimming pools), which drove up sea levels around the world.

The findings show how the massive ice sheets at the far ends of the planet will affect millions of people on coastlines everywhere.

In early February, the Centers for Disease Control and Prevention was looking for ways to stop the novel coronavirus before it got out of control in the United States.

What does an outdoor cat do all day? According to new research, it could be taking a heavy toll on local wildlife.

A tracking study of more than 900 house cats shows when they kill small birds and mammals, their impact is concentrated in a small area, having a bigger effect than wild predators do.

Deep in the Pacific Ocean, six-foot-long Humboldt squid are known for being aggressive, cannibalistic and, according to new research, good communicators.

Known as "red devils," the squid can rapidly change the color of their skin, making different patterns to communicate, something other squid species are known to do.

Widespread cancellations of commercial flights are creating problems for meteorologists around the world. That's because weather forecasting models rely on temperature and wind data gathered by thousands of planes flying overhead.

The National Weather Service uses more than 250 million measurements from aircraft every year, which are fed into complex weather computer models. As of the end of March, meteorological data provided by U.S. aircraft had dropped by half.

Academic science labs around the U.S. are rapidly gearing up to run coronavirus tests for patients in need. They're drawing resources from across campus: technology, chemicals and a formidable workforce — graduate students.

"Normally, when people say they need someone in an emergency, it's not a science grad student," says Katie Cabral, a bioengineering Ph.D. student at the University of California, San Francisco. "But in this case, my particular qualifications are exactly what is needed."

As China seeks to control the spread of COVID-19, fewer cars are driving, fewer factories are running and — in some places — skies are clearer.

Air pollution levels have dropped by roughly a quarter over the last month as coal-fired power plants and industrial facilities have ramped down so employees in high-risk areas can stay home. Levels of nitrogen dioxide, a pollutant primarily from burning fossil fuels, were down as much as 30%, according to NASA.

Winters are warming faster than other seasons across much of the United States. While that may sound like a welcome change for those bundled in scarves and hats, it's causing a cascade of unpredictable impacts in communities across the country.

Temperatures continue to steadily rise around the globe, but that trend isn't spread evenly across the map or even the yearly calendar.
