Arctic summer sea ice second lowest on record: US researchers

by Ivan Couronne with Pia Ohlin in Stockholm WASHINGTON, United States (AFP) — Arctic summer sea ice melted in 2020 to the second smallest size since records began 42 years ago, US scientists announced Monday, offering further stark evidence of the impact of global warming. Arctic sea ice melts in summer and reforms in winter, but precise satellite imagery taken regularly since 1979 documented how the cycle has been shrinking significantly. The year’s minimum was […]

Massive chunk of Greenland’s largest glacier crashes into sea

COPENHAGEN, Denmark (AFP) — A massive chunk of ice — larger than the city of Paris — has broken off from the Arctic’s largest ice shelf because of warmer temperatures in Greenland, scientists said Monday. The 113-square-kilometre (43-square-mile) block broke off the Nioghalvfjerdsfjorden glacier in Northeast Greenland, which the scientists said had been expected given the rising average temperatures. “We’re observing increasing speed on this largest remaining ice shelf,” Jason Box, professor of glaciology at […]

Greenpeace lifts Swedish refinery blockade

STOCKHOLM, Sweden (AFP) — Environmental campaigners Greenpeace said Sunday they had lifted a blockade of an oil refinery imposed to protest plans to expand it, after nearly three days of the action. The organization had since Thursday evening been blocking tankers from delivering oil to the plant, which is run by the Preem group at Lysekil, about 100 kilometres north of Gothenburg. After weeks of protests across the country against the project and a 62-hour […]

Water warning as climate risks intensify: report

by Kelly MACNAMARA LONDON, United Kingdom (AFP) — Record temperatures are accelerating the rise of sea levels, melting glaciers and snow coverage and threatening the water supplies for billions, according to a major UN report Wednesday charting the “increasing and irreversible” impacts of climate change. The multi-agency United in Science report said the world had seen its warmest five years on record in the last five years, adding that extreme weather events bore “a clear […]

Germany’s first ‘green’ bonds attract strong demand

FRANKFURT AM MAIN, Germany (AFP) — Germany on Wednesday launched its first “green” bond offering to finance environmental initiatives as it pivots towards a sustainable economy, and could become a benchmark issuer in the booming field. The government raised 6.5 billion euros ($7.7 billion), in the offering for the 10-year 0% bond, with investors placing orders of more than 33 billion euros, according to German finance agency. Even at this early stage, “Germany is well on the way […]

Climate change fuels sharp increase in glacier lakes

by Marlowe HOOD Agence France-Presse PARIS, France (AFP) — The volume of lakes formed as glaciers worldwide melt due to climate change has jumped by 50 percent in 30 years, according to a new study based on satellite data. “We have known that not all meltwater is making it into the oceans immediately,” lead author Dan Shugar, a geomorphologist and associate professor at the University of Calgary, said in a statement. “But until now there […]

Earth’s ice sheets tracking worst-case climate scenarios

by Marlowe HOOD PARIS, France (AFP) — The Greenland and Antarctic ice sheets, which hold enough frozen water to lift oceans 65 metres, are tracking the UN’s worst-case scenarios for sea level rise, researchers said Monday, highlighting flaws in current climate change models. Mass loss from 2007 to 2017 due to melt-water and crumbling ice aligned almost perfectly with the Intergovernmental Panel for Climate Change’s (IPCC) most extreme forecasts, which see the two ice sheets […]

La Nina likely, but temperatures set to remain high: UN

by Nina LARSON GENEVA, Switzerland (AFP) — Global temperatures boosted by climate change will still be higher than usual despite the cooling effect of a La Nina weather phenomenon expected to develop in the coming months, the UN said Thursday. The World Meteorological Organization (WMO) said there was a 60 percent chance of a La Nina event between September and November. But WMO chief Petteri Taalas warned in a statement that “even if a La […]

Antarctica’s glacier-damming ice shelves at risk

by Marlowe HOOD Agence France-Presse More than half the ice shelves ringing Antarctica that prevent huge glaciers from sliding into the ocean and lifting sea levels are at risk of crumbling due to climate change, researchers said Wednesday. Melt water running into deep fissures caused by warming air is undermining the structural integrity of these natural barricades, they reported in Nature. “If the ice shelves fill up with melt water, things can happen very quickly,” […]

Climate change ‘clearly’ fuelled Australia bushfires: inquest

by Andrew BEATTY Agence France-Presse SYDNEY, Australia (AFP) — Australia’s devastating 2019-2020 bushfires were “clearly” fuelled by climate change, a government inquiry reported Tuesday following some of the largest forest fires ever recorded worldwide. With this year’s fire season already underway, authorities recommended urgent action to limit the impact of extreme blazes, expected “to become more frequent” in future. The deadly bushfires raged for nine months to March and were most severe in New South Wales […]

Tropical songbirds stop breeding to survive drought

by Kelly MACNAMARA Agence France-Presse LONDON, United Kingdom (AFP) — Songbirds in tropical rainforests curtail their reproduction to help them survive droughts, according to a study Monday. Species with longer lifespans were better able to cope with this environmental volatility than previously thought, researchers found. With more record hot spells gripping parts of the planet and biodiversity threatened by human encroachment on habitats, a crucial question is whether species can adapt to these ever-harsher conditions.
