Climate & Environment
- The National Snow and Ice Data Center announced Monday that Arctic sea ice reached its likely minimum extent on Sept. 18, 2019.
- Researchers reflect on the lessons learned from a landmark multinational agreement protecting Antarctica's Ross Sea.
- Hundreds of researchers from 19 countries are launching a yearlong journey to study Arctic climate.
- Thick, impenetrable ice slabs are expanding rapidly on the interior of Greenland's ice sheet, sending meltwater spilling into the ocean.
- Researchers at the Institute of Arctic and Alpine Research (INSTAAR) have been awarded $3 million to study the changing climate and rivers of Alaska and western Canada.
- Photographers and others with a keen eye have noticed that sunrises and sunsets have become a lot more purple in the U.S. New measurements from a high-altitude balloon could explain why.
- A gene newly associated with the migratory patterns of golden-winged and blue-winged warblers could lend insight into the longstanding question of how birds migrate across such long distances.
- Dozens of CU Boulder researchers will take part in the MOSAIC expedition, which will send an icebreaker ship into the winter pack ice to drift for an entire year.
- Wildfire smoke can persist for months in the stratosphere, giving scientists an opportunity to fine-tune models of climate change, nuclear winter and geoengineering.
- Improvements in satellite imaging and remote sensing equipment have allowed scientists to measure ice mass in greater detail than ever before.
