The Arctic frequently experiences temperatures that support the formation of mixed-phase clouds that contain supercooled liquid droplets and ice crystals. The composition of such clouds plays a crucial role in the region's energy balance and climate system. Clouds with more liquid last longer and reflect more sunlight than those with more ice crystals. https://phys.org/news/2024-09-arctic-fuel-ice-formation-clouds.html Earth Sciences Thu, 19 Sep 2024 09:16:28 EDT news645956179 The few glaciers in Africa have long since become an important indicator of how rapidly and severely climate change is changing our planet. The ice on the high summits of the continent is rapidly disappearing, and Africa may lose its white peaks by the middle of our century. https://phys.org/news/2024-02-africa-ice-tropical-fields-climate.html Earth Sciences Wed, 21 Feb 2024 14:45:14 EST news627749111 Researchers at the University of Copenhagen have concluded that the methane uptake in dry landscapes exceeds methane emissions from wet areas across the ice-free part of Greenland. The results of the new study contribute important knowledge to climate models. The researchers are now investigating whether the same finding applies to other polar regions. https://phys.org/news/2024-01-greenland-absorbs-methane-emits.html Earth Sciences Wed, 31 Jan 2024 09:30:20 EST news625915603 Sea ice in Antarctica shrank to the smallest area on record in February for the second year in a row, continuing a decade-long decline, the European Union's climate monitoring service said Tuesday. https://phys.org/news/2023-03-antarctic-sea-ice.html Environment Wed, 08 Mar 2023 10:59:36 EST news597495541 Data stored in ice cores dating back 55 years bring new insight into atmospheric levels of a molecule that can significantly affect weather and climate. https://phys.org/news/2023-01-anti-greenhouse-gas-dimethyl-sulfide-arctic.html Earth Sciences Tue, 31 Jan 2023 08:44:03 EST news594377041 An international team of climate scientists has found evidence suggesting that deforestation in the Amazon rainforest is influencing weather in Tibet, more than 15,000 kilometers away. In their paper published in the journal Nature Climate Change, the researchers describe possible long-range impacts of deforestation of the Amazon rainforest. Valerie Livina, with the U.K.'s National Physical Laboratory, has published a News & Views piece in the same journal issue outlining the Hopf bifurcation theory and how it relates to climate tipping points and the work done by the team on this new effort. https://phys.org/news/2023-01-amazon-rainforest-deforestation-weather-tibet.html Earth Sciences Fri, 06 Jan 2023 10:30:01 EST news592222570 While the world focuses on limiting the rise in global temperature to 1.5 or 2 degrees Celsius over the preindustrial average, increasing meltwater from ice sheets presents an existential threat to the viability of island and coastal nations throughout the world. https://phys.org/news/2022-12-paris-agreement-temperature-worsen-climate.html Earth Sciences Tue, 13 Dec 2022 16:42:30 EST news590172146 The Arctic has warmed nearly four times faster than the rest of the planet over the last 40 years, according to research published Thursday that suggests climate models are underestimating the rate of polar heating. https://phys.org/news/2022-08-arctic-faster-rest-earth.html Earth Sciences Thu, 11 Aug 2022 11:27:35 EDT news579436049 Jumping from rock to rock to rock over a creek formed off Austria's Jamtal glacier, scientist Andrea Fischer worries that precious scientific data will be irreversibly lost as the snow and ice melt faster than ever. https://phys.org/news/2022-08-austrian-scientists-reveal-glaciers-secrets.html Environment Sun, 07 Aug 2022 05:35:02 EDT news579069297 Sea ice around Antarctica shrank to the smallest extent on record in February, five years after the previous record low, researchers said Tuesday, suggesting Earth's frozen continent may be less impervious to climate change than thought. https://phys.org/news/2022-04-antarctic-sea-ice-extent-shift.html Earth Sciences Tue, 19 Apr 2022 11:23:30 EDT news569586202 Greenland's immense ice sheet has lost enough ice in the past 20 years to submerge the entire United States in half a metre of water, according to data released this week by Danish researchers. https://phys.org/news/2022-02-greenland-ice-cap-years.html Environment Tue, 01 Feb 2022 14:00:03 EST news562945521 Rain fell at the highest point on Greenland's ice sheet—possibly for the first time—in an event Danish scientists on Monday said was most likely driven by climate change. https://phys.org/news/2021-08-greenland-ice-sheet-climate.html Environment Mon, 23 Aug 2021 13:06:39 EDT news548942797 The UN Intergovernmental Panel on Climate Change's first major scientific assessment since 2014, released Monday, shows unequivocally that global warming is unfolding more quickly than feared and that humanity is almost entirely to blame. https://phys.org/news/2021-08-good-news-key-ipcc-climate.html Environment Mon, 09 Aug 2021 04:46:43 EDT news547703198 A huge ice block has broken off from western Antarctica into the Weddell Sea, becoming the largest iceberg in the world and earning the name A-76. https://phys.org/news/2021-05-world-largest-iceberg-antarctica-european.html Environment Thu, 20 May 2021 06:18:15 EDT news540710293 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. https://phys.org/news/2020-09-climate-fuels-sharp-glacier-lakes.html Environment Tue, 01 Sep 2020 05:36:58 EDT news518157414 The kilometres-thick icesheet that covers Greenland saw a near-record imbalance last year between new snowfall and the discharge of meltwater and ice into the ocean, scientists have reported. https://phys.org/news/2020-04-alarms-greenland-ice-loss-sea.html Earth Sciences Thu, 16 Apr 2020 15:43:41 EDT news506270613 Greenland and Antarctica are shedding six times more ice than during the 1990s, driving sea level rise that could see annual flooding by 2100 in regions home today to some 400 million people, scientists have warned. https://phys.org/news/2020-03-six-fold-polar-ice-loss-global.html Earth Sciences Thu, 12 Mar 2020 04:21:51 EDT news503205705 Deep in the Sayan Mountains of northern Mongolia, patches of ice rest year-round in the crooks between hills. https://phys.org/news/2019-11-mongolian-ice-patches-threaten-reindeer.html Archaeology Wed, 20 Nov 2019 14:00:02 EST news493460272 Rainy weather is becoming increasingly common over parts of the Greenland ice sheet, triggering sudden melting events that are eating at the ice and priming the surface for more widespread future melting, says a new study. Some parts of the ice sheet are even receiving rain in winter—a phenomenon that will spread as climate continues to warm, say the researchers. The study appears this week in the European scientific journal The Cryosphere. https://phys.org/news/2019-03-greenland-icein-winter.html Earth Sciences Thu, 07 Mar 2019 09:00:10 EST news471168920 Researchers from the Universities of Bremen and Innsbruck have shown in a recent study that the further melting of glaciers cannot be prevented in the current century—even if all emissions were curtailed. However, due to the slow reaction of glaciers to climate change, human activity will have a massive impact beyond the 21st century. In the long run, 500 meters by car with a mid-range vehicle will cost one kilogram of glacier ice. The study has now been published in Nature Climate Change. https://phys.org/news/2018-03-glacier-mass-loss.html Earth Sciences Tue, 20 Mar 2018 06:38:09 EDT news440746678 Last year, the Earth sweltered under the hottest temperatures in modern times for the third year in a row, US scientists said Wednesday, raising new concerns about the quickening pace of climate change. https://phys.org/news/2017-01-earth-year-row.html Environment Wed, 18 Jan 2017 11:02:08 EST news403959722 Fishing line, paper clips, glass marble, glue - no, not the makings of a MacGyver episode but a new experiment that lets students precisely measure the effects of global warming on oceans. https://phys.org/news/2015-10-macgyver-dyi-students-physics-climate.html General Physics Thu, 08 Oct 2015 11:04:09 EDT news363521037 There have been instances in Earth history when average temperatures have changed rapidly, as much as 10 degrees Celsius (18 degrees Fahrenheit) over a few decades, and some have speculated the same could happen again as the atmosphere becomes overloaded with carbon dioxide. https://phys.org/news/2011-06-atmospheric-carbon-dioxide-buildup-abrupt.html Earth Sciences Mon, 20 Jun 2011 09:39:48 EDT news227781558
