• A team of scientists has discovered that a 1°C rise in local sea temperature has massive impacts on an Antarctic marine community. These new results are published this week (31 August) in the journal Current Biology, and enable researchers to better understand the biological implications of the future ocean warming predicted by the Intergovernmental Panel on Climate Change (IPCC).

  • As of this morning, 57 USGS streamgages are over National Weather Service flood levels, and water continues to rise at 118 gauges throughout Texas.  

    Seventeen USGS field crews are measuring high flood flows and verifying streamgage operations on the Colorado, Brazos, San Jacinto and Trinity River basins. Preliminary data show record high flood levels were measured at 16 locations throughout the greater Houston area. Accessing specific locations has proved challenging due to road closures and many sites being flooded at levels too dangerous to measure at this time.

  • Ocean acidification can be a daunting topic to cover in the classroom, but for Washington state’s coastal communities, the issue is often personal.

    Ocean acidification can be a daunting topic to cover in the classroom, but for Washington state’s coastal communities, the issue is often personal. In 2005, billions of oysters died along the Northwest coast, and NOAA scientist Richard Feeley and other North American scientists have linked this and other shellfish die-offs deaths to falling ocean pH1. According to Washington State’s Blue Ribbon Panel on Ocean Acidification, Washington’s ocean waters are specifically susceptible to ocean acidification because of coastal upwelling. This brings water that is low in pH and rich in carbon dioxide up from the deep ocean and onto the continental shelf. Ocean acidification, also exacerbated by nutrient runoff and local carbon emissions, threatens Washington’s marine environment, the state and local economies, and tribes.

  • The National Hurricane Center (NHC) upgraded a low pressure area in the far eastern Atlantic Ocean to tropical storm Irma on August 30, 2017 at 11 a.m. EDT (1500 UTC).

    Tropical cyclones that form in that part of the Atlantic Ocean are often the largest and most powerful hurricanes of the season. Hurricanes Ivan (2004), Isabel (2003), Hugo (1989) and Allen (1980) are examples of past powerful hurricanes that formed near the Cape Verde islands.

  • Warming event that took place 56 million years ago led to significant ecological disruption and could shed light on modern climate change.

  • Potential tropical cyclone 14E of the Eastern Pacific Ocean hurricane season appeared to be coming together off the southwestern coast of Mexico. NASA’s Aqua satellite captured temperature data on the storm that is producing torrential rains over southwestern Mexico.

    Because of the large system’s proximity to land, it has spawned warnings and watches. A Hurricane Watch is in effect from Puerto Cortes to Los Barriles, Mexico. A Tropical Storm Warning is in effect for Todos Santos to Los Barriles, and a Tropical Storm Watch is in effect from north of Los Barriles to San Evaristo, Mexico.

  • NASA analyzed the soil moisture in southeastern Texas before and after Harvey made landfall and found the ground was already somewhat saturated. NASA-NOAA’s Suomi NPP Satellite provided a night-time look at Harvey after it moved into the Gulf of Mexico, and NOAA’s GOES East satellite provided a look at the storm after it made its final landfall near the Texas-Louisiana border on Aug. 30.

  • Two species of songbirds that once made a home in the Bahamas likely became extinct on the islands because of rising sea levels and a warmer, wetter climate, according to a new study by researchers at the University of California, Riverside and the University of Florida, Gainesville. The study, which was published today in the Proceedings of the National Academy of Sciences, presents a historical view of how climate change and the resulting habitat loss can affect Earth’s biodiversity.

  • In the coming decades, warming ocean temperatures could stunt the growth of fish by as much as 30 percent, according to a new study in the journal Global Change Biology.

    The main driver behind this decline in size is that warmer water contains less oxygen. As Nexus Media explains, fish are cold-blooded animals and therefore cannot regulate their own body temperatures. So as oceans heat up, a fish’s metabolism accelerates to cope with the rising temperatures and they need more oxygen to sustain their body functions. But fish gills do not grow at the same pace as the rest of their body, resulting in a decline of oxygen supply and in growth.

  • The Great Barrier Reef, and most other large reefs around the world, owe their bulk in large part to a type of red algae that grows on corals and strengthens them. New research led by Anna Weiss, a Ph.D. candidate at The University of Texas at Austin Jackson School of Geosciences, has found that ancient coral reefs were also bolstered by their bond with red algae, a finding that could help scientists better understand how reefs will respond to climate change.

    “Coral reefs as we know them today are a product of that long term coral-coralline algae relationship,” Weiss said. “So if we want to preserve our coral reefs, we need to pay attention to the health of coralline algae as well.”
