Earth & Climate News -- ScienceDaily
  1. Scientists explain the art of creating digital hurricanes
    A team of scientists spends its days incorporating millions of atmospheric observations, sophisticated graphic tools and lines of computer code to create computer models simulating the weather and climate conditions responsible for hurricanes.
  2. Saving Nemo: Bleaching threatens clownfish
    Clownfish became a household name over a decade ago when Disney released the movie 'Finding Nemo.' The colorful fish are now at risk due to bleaching of their sea anemone homes in the Indo-Pacific, which has increased due to rising ocean temperatures. Researchers demonstrate how vulnerable clownfish are to the increased frequency of bleaching events.
  3. Early use of 'hurricane hunter' data improves hurricane intensity predictions
    Data collected via airplane when a hurricane is developing can improve hurricane intensity predictions by up to 15 percent, according to researchers who have been working to put the new technique into practice.
  4. Common antibacterial triclosan found in most freshwater streams
    Most U.S. homes are full of familiar household products with an ingredient that fights bacteria: triclosan. Most of the triclosan is removed in waste water treatment plants. However, a U.S. Geological Survey found the antibacterial in nearly 58% of freshwater streams. What does that mean for the food and soil irrigated with water from streams? As triclosan breaks down, it can turn into other harmful compounds. The breakdown of triclosan produces more effective hormone disruptors.
  5. Many unknown chemicals in the Baltic Sea
    New chemicals are often not recognized in analyses of fish in the Baltic Sea, shows a new study. The reason is that one chooses to search for chemicals that are already known, and much of those who are already regulated by law. Many toxic chemicals that are not yet regulated are often overlooked in the environmental monitoring.
  6. Spring comes sooner to urban heat islands, with potential consequences for wildlife
    With spring now fully sprung, a new study shows that buds burst earlier in dense urban areas than in their suburban and rural surroundings. This may be music to urban gardeners' ears, but that tune could be alarming to some native and migratory birds and bugs.
  7. The future of sonar in semiheated oceans
    Light doesn't travel very far underwater so the navy uses sound to transmit messages. The speed of underwater sound depends on a combination of temperature, salinity and pressure. Understanding sound speed is crucial for transmitting messages, detecting enemy submarines and avoiding marine animals. As climate change elevates temperatures, understanding underwater sound speed will become increasingly important.
  8. Rigid water pipes, fit for the future
    Researchers have developed a modern, intelligent and sustainable water energy transition concept for urban areas. It will be implemented during the next three years in the city of L√ľnen, Westphalia.
  9. Using solid-state materials with gold nanoantennas for more durable solar cells
    Scientists are testing the development of solar cells made of solid materials to improve their ability to function under harsh environmental conditions.
  10. Why some climate processes are more effective at warming Earth
    A new paper explains why some climate processes are more effective than others at warming/cooling the Earth. By accounting for these differences we can more accurately determine the most important drivers of climate change in sensitive regions like the Arctic.
