The Black Death is immortalized by the plague masks of Venice, like this stylized version used in a Carnival costume.

Plague Pandemic May Have Been Driven by Climate, Not Rats

The bacteria responsible for the Black Death were reintroduced to Europe multiple times, possibly due to the changing climate

Navajo activist Delores Wilson opposes development on land she holds sacred: “You don’t want to anger the Holy Beings there.”

Ask Smithsonian: What’s the Deepest Hole Ever Dug?

The answer to the question, says a Smithsonian researcher, is more about why we dig, than how low you can go

The Cliff Palace in Mesa Verde National Park in Colorado was abandoned hundreds of years ago, probably because of a severe drought. Scientists now predict that the region could experience an even worse megadrought in the latter half of the 21st century.

The Western U.S. Could Soon Face the Worst Megadrought in a Millennium

Climate models predict that the region will be drier than the droughts that likely caused ancient Native Americans to abandon their pueblo cities

How to Save the Chocolate Tree Without Sacrificing Flavor

Demand, disease and climate change are threatening cocoa, but a new breed of clones could keep the treat abundant and tasty

The abandoned city of Machu Picchu is one legacy of the Spanish conquest of the Incas. Traces of air pollution in a Peruvian ice cap are another.

Spanish Conquest of the Incas Caused Air Pollution to Spike

A sample of Peruvian ice has revealed a surge in pollution linked to mining that wasn’t exceeded until the Industrial Revolution

Spire’s Austin Ellis shows off a satellite frame at Spire's San Francisco headquarters. Components, like the weather sensor, stack on top of each other inside the frame. Solar panels and antennae fold out from the frame once the device is in orbit.

New Satellite Network Launching This Year Aims to Improve Weather Forecasting

With a network of compact, low-cost weather satellites with smartphone-like internals, startup Spire plans to make future forecasts a lot more reliable

Scientists Have Imaged the Base of a Tectonic Plate

The discovery of a slippery layer off the coast of New Zealand could help explain plate movement

Faced with the only high-cost options, Smithsonian researcher Whitman Miller began building his own portable, inexpensive monitoring stations.

Saving Money is Great, but Saving the Chesapeake Bay Will Be Even Better

Whitman Miller’s “off the shelf” technology may answer complicated questions about rising CO2 and ocean acidification

A satellite image shows the huge snowstorm that blanketed the northeastern United States this week. The blizzard was an example of how storms are getting less common but more intense.

Climate Change Is Altering the Global Heat Engine

Thermodynamics help explain why storms will become fewer in number but stronger in intensity as the planet warms

The World Hit “Peak Chicken” in 2006

The popular poultry is just one of many key food resources that hit peak production between 5 and 30 years ago

The western tarsier, a rare primate species, has lost large amounts of its Borneo habitat to logging. More of that habitat is likely to disappear because of climate change.

Borneo’s Mammals Face a Deadly Mix of Logging and Climate Change

But adding small amounts of land to already protected areas could help save the island’s biodiversity
