TODAY'S FUN LINKS:

Determining an Efficient Method for Measuring Coastal Currents Texas A&M University - 22 January 2026 In a study published in the Journal of Atmospheric and Oceanic Technology, researchers identified an ideal method for measuring surface currents over large areas that uses drones and wave-based current mapping. Extensive Freshened Water Beneath the Ocean Floor Confirmed for the First Time Colorado School of Mines - 4 February 2026 The discovery comes from the initial analyses of sediment cores retrieved from deep below the seafloor, and provides the first detailed evidence of long-suspected hidden freshwater aquifers. Computer Simulations Show Strong Ocean Currents Reduce Size of the Surface Waves University of Rhode Island - 5 February 2026 Recent research in the Journal of Physical Oceanography used advanced computer simulations to determine how much hurricane-driven ocean currents modify surface waves and why it happens.   Trump’s EPA Decides Climate Change Doesn’t Endanger Public Health—The Evidence Says Otherwise The Conversation - 12 February 2026 The administration's arguments in dismissing the health risks of climate change are not only factually wrong, they’re deeply dangerous to Americans’ health and safety. As the World Warms, Freezing Rain Shifts to the U.S. South (may require subscription) Science - 3 February 2026 A handful of scientists are studying how freezing rain might be changing in a warming world. One early result: Freezing rain isn’t vanishing, but it is shifting in location and timing. Scientists Work to Uncover Rare Mediterranean Hurricanes The Weather Network - 15 February 2026 Hurricane-like storms sometimes form in the Mediterranean sea, and a recent BAMS study proposed a set definition to classify these storms in the future. What the National Center for Atmospheric Research Means to the Atmospheric Sciences Physics Today - 12 February 2026 Born out of a time of great need for the federal government, NCAR plays a role with few analogues. New Computer Simulations Reveal the Earth System in Unprecedented Detail NCAR - 4 February 2026 A team of scientists has created an unprecedented set of high-resolution Earth system simulations that is freely available to the scientific community. Weather and Science Shape Every Snowflake. Here's How. Weather Underground - 6 February 2026 The journey of a single snowflake is anything but ordinary—and it involves chemistry, clouds, and just the right atmospheric conditions. Unexpected Climate Feedback Links Antarctic Ice Sheet with Reduced Carbon Uptake Columbia University - 2 February 2026 New research reveals a surprising link between West Antarctic Ice Sheet retreat and algae growth over the past 500,000 years. The Colorado River Is Having Its Driest Winter in Decades KJZZ - 9 February 2026 A new water supply outlook for the month of February is the worst in the last 35 years, and every single region where federal authorities track snowpack is below average for this time of year.
