Antarctic ice levels undergo ‘massive decrease’, data shows

July 10, 2023810 Views

Antarctic sea ice levels reached record lows last month, the World Meteorological Organization (WMO) said on Monday, a development climate change experts described as worrisome. WMO said that Antarctic sea ice levels last month - the hottest June ever recorded -- were at their lowest since satellite observations began, at 17% below average.

This is a massive decrease," Michael Sparrow, Chief of World Climate Research Programme, told reporters in Geneva. Global sea surface temperatures were at record high for the time of the year in May and June, according to WMO, which warned that ...

Earth keeps breaking temperature records due to global warming On Monday, the global average temperature was the highest it’s ever been. It was even hotter on Tuesday. June was hottest June on record globally Global temperatures have smashed through records this week, underscoring the dangers of ever-increasing greenhouse gas emissions generated from burning fossil fuels. The average worldwide temperature reached 17C (63F) on Monday, just above the previous record of 16.9C in August 2016, according to data from the National Centers for Environmental Prediction. The threshold only lasted a day. On Tuesday, July 4, 2023, the average temperature hit 17.2C. This past June was also the hottest June globally on record in terms of sea and air temperatures, according to a statement by ...

Temperatures seen surging as El Nino weather pattern returns

Temperatures are expected to soar across large parts of the world after the El Nino weather pattern emerged in the tropical Pacific for the first time in seven years, the World Meteorological Organization said on Tuesday. El Nino, a warming of water surface temperatures in the eastern and central Pacific Ocean, is linked to extreme weather conditions from tropical cyclones to heavy rainfall to severe droughts. The world's hottest year on record, 2016, coincided with a strong El Nino - though experts says climate change has fuelled extreme temperatures even in years without the phenomenon.

Climate change fuels weather extremes in 2023 The target of keeping long-term global warming within 1.5 degrees Celsius (2.7 Fahrenheit) is moving out of reach, climate experts say, with nations failing to set more ambitious goals despite months of record-breaking heat on land and sea. As envoys gathered in Bonn in early June to prepare for this year's annual climate talks in November, average global surface air temperatures were more than 1.5C above pre-industrial levels for several days, the EU-funded Copernicus Climate Change Service (C3S) said.

Warming causes more extreme rain, not snow, over mountains

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.

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...
