Warming decimates Antarctica"s emperor penguin chicks
Helpless emperor penguin chicks perished at multiple breeding grounds in West Antarctica late last year, drowning or freezing to death when sea ice eroded by global warming gave way under their tiny feet, scientists said Thursday......»»
As human activities expand in Antarctica, scientists identify crucial conservation sites
A team of scientists led by the University of Colorado Boulder has identified 30 new areas critical for conserving biodiversity in the Southern Ocean surrounding Antarctica. In a study published Aug. 15 in the journal Conservation Biology, the resear.....»»
Antarctica winter experiences prolonged heat wave
Antarctica, the world's coldest continent, is experiencing an exceptionally long heat wave during its winter, according to Britain's national polar research institute......»»
Shipping emissions regulations enacted in 2020 improved air quality but accelerated warming, study finds
Last year marked Earth's warmest year on record. A new study finds that some of 2023's record warmth, nearly 20%, likely came as a result of reduced sulfur emissions from the shipping industry. Much of this warming is concentrated over the northern h.....»»
Changing food consumers" choices may help cut greenhouse gases
Planet-warming greenhouse gas emissions associated with the global food supply chains induced by diets could fall by 17% if people change their food choices towards more plant-based diets, a new study reveals......»»
First map of vegetation across Antarctica reveals a battle for the continent"s changing landscape
A tiny seed is stuck between loose gravel and coarse sand. There is nothing else alive around it. All it can see is a wall of ice reaching 20 meters up into the sky. It is cold. Survival is hard around here. In winter, it is dark even during the day......»»
Volcanic eruptions that warmed the planet millions of years ago shed light on how plants evolve, regulate climate
Scientists often seek answers to humanity's most pressing challenges in nature. When it comes to global warming, geological history offers a unique, long-term perspective......»»
Weather "whiplash" in Antarctica may help predict effects of future climate change
The McMurdo Dry Valleys of Antarctica live up to their name. The region is one of the driest places on Earth—mountains form a wall around the valleys and prevent melting glacier water from intruding, humidity is extremely low, and no rain was docum.....»»
Farm Effort to Reduce Methane Emits a Different Climate-Warming Gas
Scientists say efforts to tame methane in agriculture can spur the output of another greenhouse gas: nitrous oxide.....»»
South Florida estuaries warming faster than Gulf of Mexico, global ocean, research shows
Sea surface temperatures are on the rise around the world, but the problem is pronounced in South Florida, according to a series of studies published by researchers at the University of South Florida College of Marine Science......»»
New 400-year temperature record shows Great Barrier Reef is facing catastrophic damage, researchers warn
The Great Barrier Reef is under critical pressure, with warming sea temperatures and mass coral bleaching events threatening to destroy the remarkable ecology, biodiversity, and beauty of the world's largest coral reef, according to new research......»»
Modern aircraft emit less carbon than older aircraft, but their contrails may do more environmental harm
Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found......»»
Tundra vegetation to grow taller, greener through 2100, study finds
Warming global climate is changing the vegetation structure of forests in the far north. It's a trend that will continue at least through the end of this century, according to NASA researchers. The change in forest structure could absorb more of the.....»»
Climate risks from exceeding 1.5°C reduced if warming swiftly reversed, says study
Earth systems could be "tipped" into unstable states if warming overshoots the 1.5°C target, but impacts could be minimized if warming is swiftly reversed......»»
Study yields new insights into the link between global warming and rising sea levels
A McGill-led study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the curre.....»»
Ancient Antarctic microorganisms are aggressive predators
In Antarctica there is a small lake, called Deep Lake, that is so salty it remains ice-free all year round despite temperatures as low as -20°C in winter. Archaea, a unique type of single-celled microorganism, thrive in this bitterly cold environmen.....»»
3D terrestrial laser scanner assists in reconstructing glacier"s mass balance sequence
Complex topography of glacier surfaces under accelerating global warming presents unprecedented challenges to traditional methods of glaciological observation due to intense fragmentation and differential melting......»»
Penguin wing fossil shows importance of Zealandia in penguin evolution
Three small fossil penguin bones, collected in South Canterbury in 1987, are now shedding new light on how penguin wings have evolved. A new study, published in the Journal of the Royal Society of New Zealand, describes a new species of penguin that.....»»
Atmospheric rivers shape long-term changes in Arctic moisture variability
Recent decades have seen rapid warming in the Arctic, known as Arctic amplification, which has impacted the Arctic's cryosphere and ecosystems and influenced global weather and climate through changes in atmospheric circulation......»»
Tipping risks from overshooting 1.5°C can be minimized if warming is swiftly reversed, says research
Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5°C of global warming after a period of overshoot. A new study indicates that these risks can be minimized if warming is.....»»
Underwater mapping reveals new insights into melting of Antarctica"s ice shelves
An international research team—including scientists from the University of East Anglia (UEA)—deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica. The underwater vehicle, "Ran," was programmed to dive into the cavity.....»»
