  • Marine Species Threatened by Deep-Sea Mining

    Less than half of our planet’s surface is covered by land. The rest is water, and this environment is home to an enormous range of animal species, most of which remain undiscovered and thus have not yet been named.

  • Sea Level Rise Could Flood 1.9 Million U.S. Homes by 2100

    An estimated 1.9 million U.S. homes could be flooded by 2100 if seas rise 6 feet in response to climate change, according to a new analysis by the real estate company Zillow. The affected properties are valued at $916 billion dollars and represent 1.8 percent of the country’s housing stock.

  • Zebra chip pathogen found in Western Canada for the first time

    For the first time, evidence of the zebra chip pathogen has been found in potato fields in southern Alberta, but the University of Lethbridge’s Dr. Dan Johnson cautions against panic.

    “So far, the zebra chip pathogen has appeared in only small numbers of potato psyllids,” says Johnson, a biogeography professor and coordinator of the Canadian Potato Psyllid and Zebra Chip Monitoring Network. “The number of potato psyllids in all Alberta sites is very low and many sample cards have found no evidence of the potato psyllid insect. Zebra chip does not normally become a problem unless the potato psyllids are found in much higher numbers than are currently being found in Canada.”

  • Why Does Green California Pump the Dirtiest Oil in the U.S.?

    On New Year’s Day, 1909, a grocer named Julius Fried and his novice drilling crew, the Lakeview Oil Company, spudded a well in the desert valley scrub in the Midway-Sunset oil field, 110 miles north of Los Angeles.

  • Here's why your sustainable tuna is also unsustainable

    Tuna is one of the most ubiquitous seafoods. It can be eaten from a can or as high-end sashimi and in many forms in between. But some species are over-fished and some fishing methods are unsustainable. How do you know which type of tuna you’re eating?

    Some tuna is certified as sustainably caught by groups such as the Marine Stewardship Council (MSC) that set standards for sustainable fishing. But these certifications are only good if they are credible.

  • Fossil coral reefs show sea level rose in bursts during last warming

    Scientists from Rice University and Texas A&M University-Corpus Christi’s Harte Research Institute for Gulf of Mexico Studies have discovered that Earth’s sea level did not rise steadily but rather in sharp, punctuated bursts when the planet’s glaciers melted during the period of global warming at the close of the last ice age. The researchers found fossil evidence in drowned reefs offshore Texas that showed sea level rose in several bursts ranging in length from a few decades to one century.

  • Forest fires on the rise as JRC study warns of danger to air quality

    The JRC’s annual forest fires report confirms a trend towards longer and more intense fire seasons in Europe and neighbouring regions, with wildfires now occurring throughout the year. The report coincides with an international study which finds that global wildfire trends could have significant health implications due to rising harmful emissions.

  • Regreening the Planet Could Account for One-Third of Climate Mitigation

    Planting trees, restoring peatlands, and better land management could provide 37 percent of the greenhouse gas mitigation needed between now and 2030 to keep global warming to 2 degrees Celsius, according to a new study published in the Proceedings for the National Academy of Sciences.

  • Fighting fires before they spark

    With warm, dry summers comes a deadly caveat for the western United States: wildfires. Scientists say the hot, dry climates found west of the Mississippi, along with decades of fire suppression efforts, are creating a devastating and destructive combination – leading to fires like the ones currently burning in California.
