Seagrass decline poses issues for carbon storage projectsClimate change is an ever-pressing concern, with innovative ways to remove excess carbon from the atmosphere a continued focus of scientists. One such carbon sequestration method turns to an unlikely sink—seagrass—a marine flowering plant (angiosperm) that is found in shallow coastal waters up to 50m depth on all continents except Antarctica. |

Melting ice, falling snow: Sea ice declines enhance snowfall over West AntarcticaAs the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise, according to Penn State scientists. |

Why do climate models underestimate polar warming? ‘Invisible clouds’ could be the answerStratospheric clouds over the Arctic may explain the differences seen between the polar warming calculated by climate models and actual recordings, find researchers from UNSW Sydney. |

Study projects how mountain climate systems will change with rising carbon dioxideMountains create their own weather or climate systems by changing airflow and precipitation patterns. Orographic, or mountain-influenced, precipitation occurs as moisture-laden air rises over the high topography; the air cools, condenses, and releases water; and the atmosphere warms with latent heat. But as the world warms and emissions of greenhouse gases such as carbon dioxide (CO2) increase, predicting changes in mountain precipitation is becoming more complex. |

New AI system can map giant icebergs from satellite images 10,000 times faster than humansScientists have trained an artificial intelligence (AI) system to accurately map—in one-hundredth of a second—the surface area and outline of giant icebergs captured on satellite images. The paper, titled “Mapping the extent of giant Antarctic icebergs with Deep Learning,” is published in The Cryosphere. |

Red hot October almost guarantees 2023 will be the hottest year on recordThis October was the hottest on record globally, 1.7 degrees Celsius (3.1 degrees Fahrenheit) warmer than the pre-industrial average for the month—and the fifth straight month with such a mark in what will now almost certainly be the warmest year ever recorded. |

Nasty drought in Syria, Iraq and Iran wouldn’t have happened without climate change, study findsA three-year drought that has left millions of people in Syria, Iraq and Iran with little water wouldn’t have happened without human-caused climate change, a new study found. |

Study suggests link between feral horses and peatland carbon emissionsA new study by RMIT has found carbon emissions from Australian alpine peatlands to be much higher in areas disturbed by feral horses. The paper, “Carbon emissions from Australian Sphagnum peatlands increase with feral horse (Equus caballus) presence,” was published in the Journal of Environmental Management . |

New analysis finds strong El Niño could bring extra floods this winterAn analysis by NASA’s sea level change science team finds that if a strong El Niño develops this winter, cities along the western coasts of the Americas could see an increase in the frequency of high-tide flooding that can swamp roads and spill into low-lying buildings. |

Fossil fuel plans by producing nations threaten global climate goals: UNPlans to expand oil, gas and coal production by major fossil fuel countries would push the world far beyond agreed global warming limits and are “throwing humanity’s future into question”, the UN warned Wednesday. |
