Winter temperatures in Russia have risen by an average of 3 degrees Celsius over the past half-century, a leading climate expert told state media on Monday. “It’s a little more in the Arctic and a little less in the south of Russia,

Russia's legendary cold winters are not what they used to be. Early snowdrops, mild January temperatures and a lack of ice on rivers and lakes are all unwelcome signs of climate change, according to plant scientists and meteorologists.

Nearly three years into the war, Ukrainians have grown used to bracing for brutal winters with electricity blackouts and heating cuts from Russian attacks on the country’s energy infrastructure. Greenpeace warned in November that Ukraine’s power grid faced a "heightened risk of catastrophic failure.

On January 28, the Bulletin of the Atomic Scientists updated the Doomsday Clock from 90 to 89 seconds until "midnight," as world-ending threats continue escalating at

The Trump administration will be freed from its predecessor’s fixation on climate change and obsession with the quixotic, painful and ultimately fruitless task of trying to swiftly end reliance on fossil fuels.

Climate change and efforts to curb it by moving away from fossil fuels are both threatening the rights and livelihood of Sami indigenous people in the Arctic, Amnesty International said Friday. "Climate change threatens the culture and existence of the Sami indigenous people in two ways,

It is now a weapon being used against us.” Trump’s skepticism about U.S. support for Ukraine and Taiwan, his eagerness to impose tariffs, and his threats to retake the Panama Canal, absorb Canada, and acquire Greenland make it clear that he envisions a return to nineteenth-century power politics and spheres of interest,

In 2019, then-President Donald Trump suggested the United States “buy Greenland” — as a matter of national security. Now in office again, Trump has continued to push for acquisition of the island, illustrated by a recent “horrendous” call with Denmark’s prime minister just last week on the matter.

Atomic scientists on Tuesday moved their "Doomsday Clock" closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine, tensions in other world hot spots, military applications of artificial intelligence and climate change as factors underlying the risks of global catastrophe.

Seventy-eight years ago, scientists created a unique sort of timepiece — named the Doomsday Clock — as a symbolic attempt to gauge how close humanity is to destroying the world.

What is the Doomsday Clock? It's 2025 and scientists have reset the clock closer to midnight and global catastrophe. Here's what it all means.
