    Grand Canyon’s age revised, again

    The Grand Canyon is much younger than previous research had suggested, a new study says.

  5. Climate

    Greenhouse effect from fossil fuels felt almost immediately

    The warming caused by burning fossil fuels is surpassed within months by the greenhouse gas effect of the released carbon dioxide, new research shows.

  6. Climate

    Global warming ‘hiatus’ just an artifact, study finds

    Skewed data may have caused the appearance of the recent global warming hiatus, new research suggests.

  10. Climate

    Everest could lose most of its ice by 2100

    The Everest region of the Himalayas could lose 73 to 96 percent of its ice by 2100, new research predicts.

  11. Climate

    Next icy era may be on hold

    Carbon emissions from humans may have postponed Earth’s next glaciation, new research suggests.

  12. Climate
