Warming causes more extreme rain, not snow, over mountains

June 29, 2023673 Views

A warming world is transforming some major snowfalls into extreme rain over mountains instead, somehow worsening both dangerous flooding like the type that devastated Pakistan last year as well as long-term water shortages, a new study found. Using rain and snow measurements since 1950 and computer simulations for future climate, scientists calculated that for every degree Fahrenheit the world warms, extreme rainfall at higher elevation increases by 8.3% (15% for every degree Celsius), according to a study in Wednesday’s journal Nature. Heavy rain in mountains causes a lot more problems than big snow, including flooding, landslides and erosion, scientists said. And the rain isn’t conveniently stored away like snowpack that can recharge reservoirs in spring and summer. FILE PHOTO:...

Himalayan glaciers on track to lose up to 75% of ice by 2100

# Glacier loss was as much as 65% faster in 2010s compared with 2000s # 30% to 50% of glacial ice will be lost by 2100 at 1.5C of warming # Region expected to hit 'peak water' by mid-century, followed by shortages Glaciers in Asia’s Hindu Kush Himalaya could lose up to 75% of their volume by century’s end due to global warming, causing both dangerous flooding and water shortages for the 240 million people who live in the mountainous region, according to a new report. A team of international scientists has found that ice loss in the region, home to the famous peaks of Everest and K2, is speeding up. During the 2010s, the glaciers shed ice as much as 65% faster than they had in the preceding decade, according to the assessment by the Kathmandu-based International Centre for ...

Europe’s 2022 summer heat record not a ‘one-off’

Europe's summer last year was the hottest on record and caused thousands of deaths, a joint report by World Meteorological Organization and European Union scientists confirmed, while warning that such events could become more routine. The report on the state of the climate said Europe was the fastest warming continent on the planet, with the temperature having risen by about twice the global average since the 1980s. Heatwaves led to some 16,000 excess deaths last year in Europe, said the report, which was published on Monday.

Human-caused climate change at the center of recent California wildfires

Summer wildfire seasons in California routinely break records. The average summer burn area in forests in northern and central portions of the state have increased five times higher between 1996 and 2021 than between 1971 and 1995. Although the drivers of increased temperature and dryness are known, the contribution of human-caused climate change to wildfire activity, relative to natural climate variation, is unclear.

Canada is on track for its worst-ever year of wildfire destruction as warm and dry conditions are forecast to persist through to the end of the summer after an unprecedented start to the fire season, officials said on Monday. Blazes are burning in nearly all Canadian provinces and territories, and federal government officials said their modeling shows increased wildfire risk in most of Canada through August.

We are exceeding most of Earth’s limits

Earth is ‘really quite sick now’ and in danger zone in nearly all ecological ways, study says In 2009, a seminal paper in Nature showed that humanity had crossed three of nine ‘Earth-system boundaries’: the limits of what the planet can support before human activities make it uninhabitable. Now, there’s a reboot of the extraordinarily influential concept that takes into account how changes to climate, ecosystems and other factors disproportionately affect vulnerable communities. We have crossed seven of the eight safe and just boundaries. Only air pollution was inside dangerous limits globally, despite it causing an estimated 4.2 million deaths annually. Earth has pushed past seven out of eight scientifically established safety limits and into “the danger zone,” not just for an ov...

Climbers celebrate Everest 70th anniversary amid melting glaciers, rising temperatures

As the mountaineering community prepares to celebrate the 70th anniversary of the conquest of Mount Everest, there is growing concern about temperatures rising, glaciers and snow melting, and weather getting harsh and unpredictable on the world’s tallest mountain. Since the 8,849-meter (29,032-foot) mountain peak was first scaled by New Zealander Edmund Hillary and his Sherpa guide Tenzing Norgay in 1953, thousands of climbers have reached the peak and hundreds of lost their lives.

Britain’s record holding climber says highest peak is now 'dry, more rocky' Mount Everest is losing snow and turning "dry and rocky", British climber Kenton Cool, who made his 17th ascent of the world’s highest peak this week, the most by a foreigner, said on Saturday. The 49-year-old Cool, who climbed the 8,849-metre (29,032 foot) peak for the first time in 2004, said the giant mountain appears to be drying now.

Global temperature likely to rise 1.5 degrees Celsius for the first time in 5 years

For the first time ever, global temperatures are now more likely than not to breach 1.5 degrees Celsius (2.7 degrees Fahrenheit) of warming within the next five years, the World Meteorological Organization (WMO) said on Wednesday. This does not mean the world would cross the long-term warming threshold of 1.5C above preindustrial levels set out in the 2015 Paris Agreement. But a year of warming at 1.5C could offer a glimpse of what crossing that longer term threshold, based on the 30-year global average, would be like.

Fears mount for the Arctic as cooperation with Russia stalls

For nearly three decades, the Arctic Council has been a successful example of post-Cold War cooperation. Its eight members, including Russia and the United States, have cooperated on climate-change research and social development across the ecologically sensitive region. Now, a year after council members stopped working with Russia following its invasion of Ukraine and as Norway prepares to assume the chairmanship from Moscow on May 11, experts are asking whether the polar body's viability is at risk if it cannot cooperate with the country that controls over half of the Arctic coastline. An ineffective Arctic Council could have dire implications for the region's environment and its 4 million inhabitants who face the effects of melting sea ice and the interest of non-Arctic countr...
