Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity.

  1. Climate

    Arctic algae show climate change

    Sediment from Arctic lakes shows that much of the Northern Hemisphere has been warming for many decades.

  2. Climate

    A change in climate

    Global warming may be wiping out some plants and animals or pushing them into new habitats.

  3. Environment

    An ocean view’s downside

    Population growth in coastal areas could threaten shoreline ecosystems.

  4. Plants

    City trees beat country trees

    Cottonwood trees grow better in New York City than in rural places around the state.
