Glacier melt will lead to ice-free peaks in California for first time in human history

New research shows massive glaciers in Sierra Nevada projected to melt away by the beginning of the next century

Deep in California’s Sierra Nevada, massive glaciers are disappearing and projected to melt away completely by the beginning of the next century, leaving ice-free peaks for the first time in human history, new research has found.

The mountain range’s glaciers are older than previously known, dating back tens of thousands of years, with some as old as the last ice age, according to an article published last week in Science Advances.

‘In Alaska, it’s Denali’: senators move to counter Trump’s mountain name order

Republican senator Lisa Murakowski introduces bill to require peak’s name kept on US maps, laws and regulations

The Alaska Republican US senator Lisa Murkowski has introduced legislation to officially rename North America’s tallest mountain as Denali, a counter to Donald Trump’s executive order to revert the peak’s name to Mount McKinley.

Murkowski’s bill, which was co-sponsored by her fellow Republican senator for Alaska, Dan Sullivan, would require the peak to be referred to as Denali on any US maps, laws and regulations.

Mount Everest is having a growth spurt, say researchers

River erosion has pushed the mountain upwards and added an extra 15 to 50 metres over the past 89,000 years

Climbing Mount Everest has always been a feat, but it seems the task might be getting harder: researchers say Everest is having something of a growth spurt.

The Himalayas formed about 50m years ago, when the Indian subcontinent smashed into the Eurasian tectonic plate – although recent research has suggested the edges of these plates were already very high before the collision.

Wyoming commuter highway collapses in landslide leaving gaping chasm

Chasm in Teton Pass road severs link between Idaho and Jackson as governor signs order declaring an emergency

A large chunk of a twisting mountain pass road collapsed in Wyoming, authorities said Saturday, leaving a gaping chasm in the highway and severing a well-traveled commuter link between small towns in eastern Idaho and the tourist destination of Jackson.

Aerial photos and drone video of the collapse show the Teton Pass road riven with deep cracks, and a big section of the pavement disappeared altogether. Part of the guardrail dangled into the void, and orange traffic drums marked off the danger area. The road was closed at the time of the collapse.

Artist captures the impact of climate crisis over 150 years on Mont Blanc

Paintings from a climb that retraced an 1800s route on western Europe’s highest mountain reveals the extent of the peak’s melting ice

A British landscape artist who recreated a climb made 150 years ago to document the impact of the climate crisis on western Europe’s highest mountain says what he found was so grim it reminded him of the “dark paintings” of Francisco de Goya.

James Hart Dyke ascended Mont Blanc’s ancien passage north face, the route taken in 1786 by the first climbers to reach the summit. It was also the same one taken in August 1873 by French painter Gabriel Loppé, whose climb inspired Hart Dyke’s own.

Half of glaciers will be gone by 2100 even under Paris 1.5C accord, study finds

If global heating continues at current rate of 2.7C, losses will be greater with 68% of glaciers disappearing

Half the planet’s glaciers will have melted by 2100 even if humanity sticks to goals set out in the Paris climate agreement, according to research that finds the scale and impacts of glacial loss are greater than previously thought. At least half of that loss will happen in the next 30 years.

Researchers found 49% of glaciers would disappear under the most optimistic scenario of 1.5C of warming. However, if global heating continued under the current scenario of 2.7C of warming, losses would be more significant, with 68% of glaciers disappearing, according to the paper, published in Science. There would be almost no glaciers left in central Europe, western Canada and the US by the end of the next century if this happened.

Heatwaves put classic Alpine hiking routes off-limits

Routes that are usually safe at this time of year now face hazards as a result of warmer temperatures

Little snow cover and glaciers melting at an alarming rate in Europe’s heatwaves have put some classic Alpine hiking routes off-limits.

Usually at the height of summer tourists flock to the Alps and seek out well-trodden paths up to some of its peaks. But with warmer temperatures – which scientists say are driven by climate change – speeding up glacier melt and thawing permafrost, routes that are usually safe at this time of year now face hazards such as falling rocks released from the ice.

Yellowstone at 150: busier yet wilder than ever, says park’s ‘winterkeeper’

From the return of wildlife to the pressures of tourism and the climate crisis, Steven Fuller has seen it all in his nearly 50 years watching over America’s oldest national park

• Read more: Native Americans are at the heart of Yellowstone. After 150 years, they are finally being heard

As “winterkeeper” at Yellowstone national park, Steven Fuller lives in a rustic cedar-shingled cottage, built in 1910, set on a hill a short walk from the majestic Grand Canyon of the Yellowstone.

On balmier days, with the windows open, he can hear the roar of the 308ft Lower Falls tumbling into the chasm. In autumn, he is treated to the sound of bugling bull elk in rut or, in the middle of night, the howls of wolves.
