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

June 13, 2023831 Views

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...

Shanghai saw its hottest day in May for more than 100 years on Monday with temperatures hitting 36.1 degrees Celsius (97 degrees Fahrenheit), continuing a brutal trend of unusually hot weather in the country since March. Several southern Chinese provinces are expected to swelter under extreme heat over the next few days and weather experts have already predicted another blistering summer, a repeat of last year's record-breaking more than two-month stretch.

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...

Vanishing glaciers threaten alpine biodiversity

Researchers caution that as a result of climate change causing glaciers to melt at an unparalleled pace, invertebrates inhabiting the chilly meltwater streams of the European Alps will encounter extensive loss of their natural habitats. Numerous species are expected to become constrained to frigid environments that will endure solely at higher elevations in the mountains, and these regions will also potentially experience stress from the ski and tourism sectors or from the creation of hydroelectric facilities. The investigation, co-headed by the University of Leeds and University of Essex, urges conservationists to contemplate novel measures for safeguarding aquatic biodiversity.

Farms, wildlife at risk as Spanish wetland shrinks

Spain's Donana wetland has been a rich farming area for decades and a wildlife haven for centuries, but climate change is drying it out and has set regional and national authorities on a collision course over how to safeguard its future. Scientists, meanwhile, say the water needs of the farmers who grow thousands of tonnes of red berries per year are making the problem worse.
