From a pristinely preserved wolf pup to ancient camels, remains found in northern Canada’s frozen earth have provided remarkable glimpses into the Ice Age

Primrose in Iver, Buckinghamshire, United Kingdom. Primroses sometimes open as early as December and are native to the U.K. 

Plants Are Blossoming a Month Early in the U.K. Because of Climate Change

Earlier bloom dates could disrupt relationships between wildlife and cause species to collapse if they can’t adapt quickly enough, researchers warn

Scientists used satellites to get a birds-eye view of the jaw-dropping bolts.

Intense Lightning ‘Megaflashes’ Stretched Almost 500 Miles Across Three U.S. States

The bolts, which occurred in 2020, broke records for distance and duration

More than a third of Americans cook with gas stoves, which can emit formaldehyde, carbon monoxide, and nitric oxides.

Gas Stoves Are Worse for Climate and Health Than Previously Thought

A new study is heating up the debate over gas-powered stovetops

Hippos may appear inactive, but a recent study shows that they’re listening closely to their surroundings.

A Hippo’s Response to an Unknown Caller? A Blast of Poop and a Rowdy Holler

The lumbering animals respond calmly to their grunting and groaning friends, but a stranger’s voice often prompted a loud, filthy territorial response

Last November, a team of scientists and photographers spent 200 hours studying the vast reef during a dive expedition supported by UNESCO.

Researchers Find a Pristine Coral Reef Off the Coast of Tahiti

With rose-shaped corals as far as the eye can see, it is one of the largest healthy reefs on record

Seventy percent of all crop species depend on insects for pollination, but a new study shows a decrease in pollinators in areas exposed to air pollution.   

Air Pollution Makes It Harder for Insect Pollinators to Find Flowers

Some bug populations were reduced up to 70 percent in areas exposed to diesel exhaust and ozone contamination

Four snowboarders compete in the Women's Snowboard Cross final during the FIS Ski Cross World Cup 2022, part of a 2022 Beijing Winter Olympic Games test event. 

If Current Climate Trends Continue, the Winter Olympics Will Have Nowhere to Go

By the end of the century, only Sapporo, Japan, will be eligible to host the winter games if global warming continues at its present pace

Mammal and bird losses cut a plant’s ability to adapt to global climate change by 60 percent. Pictured: Cedar waxwing

With Fewer Animals to Move Their Seeds, Plants Are Stuck in Threatened Habitats

For many types of vegetation, the only way to migrate to a more favorable range is through the guts of mammals and birds

An artist’s redendering of MethaneSAT, a satellite that will be launched this year and will be able to find leaks of the greenhouse gas.

Innovation for Good: Game Changers

A New Generation of Satellites Is Helping Authorities Track Methane Emissions

Efforts to identify leaks of the harmful greenhouse gas are improving with advances in technology

In the last two decades, cases of Lyme disease in the U.S. have tripled. In one year, 476,000 individuals come down with flu-like symptoms accompanied by a distinct bulls-eye rash.

Lyme-Spreading Ticks May Thrive in Warmer Winter Conditions Across North America

In a new study, insects carrying the disease were more likely to survive cold or fluctuating temperatures than their uninfected peers

A tiger shark swims in the Bahamas. Over the past several decades, the predators ventured farther north in the northwestern Atlantic Ocean.

Some Tiger Sharks Are Migrating Farther North Due to Climate Change

The predator’s movements in the Atlantic Ocean could scramble ecosystems and endanger the sharks by sending them outside marine protected areas

Beavers can create shallow pools of water when they build dams, changing the landscape. 

Beavers Are Reshaping the Arctic Tundra. Here’s Why Scientists Are Concerned

Ponds made by the large rodents are causing permafrost to thaw, releasing methane and carbon dioxide once stored in the frozen Earth

Scientists identified a link between the severity of air pollution events and the amount of land that burned in nearby regions in the preceding week.

Health Risks of Smoke and Ozone Rise in the West as Wildfires Worsen

High levels of two dangerous pollutants are occurring with increasing frequency, researchers say

Robert Leverett walks through the old-growth forests in Mohawk Trail State Forest.

Old, Primeval Forests May Be a Powerful Tool to Fight Climate Change

Ecologists thought these trees had long been torn down in New England. Then Bob Leverett proved them wrong

The remarkable Hudsonian godwit.

This Wonder Bird Flies Thousands of Miles, Non-Stop, as Part of an Epic Migration

The more scientists learn about the Hudsonian godwit, the more they’re amazed—and worried

Approximately 315 different glaciers between British Columbia and Alaska have the potential to create new salmon habitat.

Melting Glaciers May Create 3,800 Miles of New Salmon Habitat by 2100
