New photos vs old: comparisons show dramatic Swiss glacier retreat – “We have never seen such a fast rate of glacial decline since the measurements have started”

By Denis Balibouse 25 November 2019 THE FURKA PASS, Switzerland (Reuters) – On the hairpin bend of a Swiss mountain pass, a Victorian-era hotel built for tourists to admire the Rhone Glacier has been abandoned now that the ice has retreated nearly 2 km (1.2 miles) uphill. Where mighty glaciers once spilled into Swiss valleys […]

Images reveal Iceland’s glacier melt – “We saw a staggering difference in a very short amount of time”

By Rebecca Morelle 25 October 2019 (BBC News) – A photography project has highlighted the extent of ice loss from Iceland’s glaciers. A team from Scotland and Iceland compared photographs taken in the 1980s with present-day drone images. They focused on the south side of the Vatnajökull ice cap, which covers about 7,700sq km of […]

Swiss glacier volume reduced by 10 per cent in only five years – More than 500 small glaciers have vanished – Over the past 12 months, two percent of total Swiss glacier volume lost

15 October 2019 (Swiss Academy of Sciences) – During the summer heatwaves of 2019, glacier melt rates reached record levels. This led to another year of major losses of ice volume, as reported by the Cryospheric Commission of the Swiss Academy of Sciences. Switzerland’s glaciers have thus shrunk by 10 per cent over the past […]

Landmark “United in Science” report brings together world’s leading climate science organizations

NEW YORK, 22 September 2019 (WMO) – The world’s leading climate science organizations have joined forces to produce a landmark new report  [pdf] for the United Nations Climate Action Summit, underlining the glaring – and growing – gap between agreed targets to tackle global warming and the actual reality. The report, United in Science, includes details on the […]

Hardy scientists trek to Venezuela’s last glacier amid chaos – “More than 50 million people in South America rely on water provision from the Andes”

By Christina Larson and Federica Narancio 24 September 2019 MERIDA, Venezuela (AP) – Blackouts shut off the refrigerators where the scientists keep their lab samples. Gas shortages mean they sometimes have to work from home. They even reuse sheets of paper to record field data because fresh supplies are so scarce. As their country falls […]

Iceland commemorates first glacier lost to global warming – “The world that we learned how it was, learned by heart as some kind of eternal fact, is not a fact any more”

By Toby Luckhurst 18 August 2019 (BBC News) – Mourners have gathered in Iceland to commemorate the loss of Okjokull, which has died at the age of about 700. The glacier was officially declared dead in 2014 when it was no longer thick enough to move. What once was glacier has been reduced to a […]

First evidence of human-caused climate change melting the West Antarctic Ice Sheet

12 August 2019 (British Antarctic Survey) – A new study published this week reveals the first evidence of a direct link between human-induced global warming and melting of the West Antarctic Ice Sheet. UK-US researchers say that curbing greenhouse gas emissions now could reduce the future sea-level contribution from this region. Ice loss in West […]

The 21 July 2018 snowline is at 975 m and the 16 September 2018 snowline is at 1400 m. Average end-of-summer snowline is 975 m; the 2018 end-of-summer snowline was the highest observed in the 73-year record. Graphic: AMS

State of the Climate in 2018: 2018 was the fourth-hottest year on record, behind 2016, 2015, and 2017

12 August 2019 (NCEI) – A new State of the Climate report [pdf] confirmed that 2018 was the fourth warmest year in records dating to the mid-1800s. Last year was the fourth warmest year on record despite La Niña conditions early in the year and the lack of a short-term warming El Niño influence until […]

Okjökull glacier remembered

By Kathryn Hansen 9 August 2019 (NASA) – On 18 August 2019, scientists will be among those who gather for a memorial atop Ok volcano in west-central Iceland. The deceased being remembered is Okjökull—a once-iconic glacier that has melted away throughout the 20th century and was declared dead in 2014. A geological map from 1901 estimated Okjökull […]

WMO: July 2019 equaled or surpassed hottest month globally – World is on track for the 2015-2019 period “to be the five hottest years on record”

1 August 2019 (WMO) – According to the new data from the World Meteorological Organization and Copernicus Climate Change Programme, July 2019 at least equalled, if not surpassed, the hottest month in recorded history. This follows the warmest ever June on record. The data from the Copernicus Climate Change Programme, run by the European Centre […]
