Permafrost is ground that has been frozen for at least two years. With the warming climate, permafrost across Alaska is thawing and greenhouse gases such as methane are released as a result. Ecologist Kristen Manies of the U.S.

The Landsat program conceived of in the 1960s, has been running longer than any remote sensing program. The idea was simple: position a satellite in a nearly polar orbit fixed to the solar angle so that each daytime pass would cross the equator at roughly the same local time.

If you're watching this video, you're probably using a lithium battery. Smartphones, tablets and laptops all rely on lithium metal to store energy. It comes from surface mines or brine ponds, found in places like Australia, China and the United States. One of the leading sources for this increasingly valuable resource is the South American nation of Chile.

A small watershed restoration project proves that land farmed for half a century can be returned to a previous state. In 2002, Mike Osterholm bought 98 acres in northeastern Iowa, most of it annually tilled cropland. The land included the confluence of Duck Creek and Waterloo Creek.

The Bay of Fundy in Canada has a unique geography funneling the Atlantic Ocean into some of the world's highest tides. At some points the water level can rise and fall over forty feet. The water's edge at Minas Basin shown in these Landsat 8 images changes dramatically depending on the day and time.

The visible impact of climate change on the Earth’s surface is often clearest in the Arctic’s receding glaciers and swelling glacial lakes. Southeastern Alaska’s Harlequin Lake is one of the fastest-growing in North America. These false color Landsat images show the rapidly-retreating Yakutat Glacier, which feeds the lake.

On December 26th, 2004, a massive 9.1 magnitude earthquake struck off the west coast of northern Sumatra, Indonesia. The third largest earthquake ever recorded lifted the sea floor several meters, causing tsunami waves to ripple out in all directions and race across the ocean. Banda Aceh bore the brunt of the waves just 15 to 20 minutes after the earthquake.

The waves of sugar cane that once defined the Hawaiian island landscape of Maui, have slowly given way to non-native annual grasses in recent decades. Those grasses have become a fire hazard along the way.

The western wall of Uzbekistan's Sardoba Reservoir breached on May 1st, 2020 after a week of heavy rain. Thousands were evacuated as water rushed north into farmland and villages across the central Asian country and into neighboring Kazakhstan. Imagery from Europe's Copernicus Sentinel-2 satellite shows water pooling across a wide area.
