  • Heatwaves, Air Conditioning, and Offshore Wind Energy

    Understanding offshore wind patterns can help scientists predict when wind speeds are likely to be highest, and therefore when future offshore wind farms would be capable of producing the most energy. In this Data Puzzle, students analyze wind speed and energy demand data to explain the investigative question, "How does the timing of peak offshore wind speeds compare with the timing of peak energy demands in New York City during a hot, summer day?

  • It's All Connected

    What makes the Arctic climate system so unique is the sea ice, which influences the Arctic climate in many ways. In this Data Puzzle, students analyze a humidity dataset captured by a drone during the historic MOSAiC Arctic expedition to investigate the question, "What effect, if any, do leads (cracks in the sea ice) have on the transfer of moisture between the Arctic Ocean and atmosphere?"

  • To Reflect or Not to Reflect

    The color of Earth's surface determines how much of the Sun's energy is reflected or absorbed (albedo), with lighter-colored surfaces being more reflective than darker-colored surfaces. In this Data Puzzle, students analyze authentic Arctic datasets (albedo and sea ice extent) to investigate the question, "How might the Arctic’s albedo be affected by the observed decline in sea ice?Figure credit: NASA.

  • On a Budget

    Rising global temperatures over the past century indicate that Earth’s energy budget is out of balance. However, not all warming is equal. The Arctic, a vast frozen ocean, is heating up faster than the global average! In this Data Puzzle, students analyze incoming shortwave and outgoing longwave energy to and from the Arctic to investigate the question, "Why might the Arctic be warming faster than other places on Earth?"

  • Tracing Carbon Through the Arctic Food Web

    Despite average winter temperatures of -30°F and being covered by sea ice for much of the year, the Arctic is home to a huge variety of living things (humans included) that have adapted to these harsh conditions. However, environmental conditions are changing. The Arctic is warming at a rate twice as fast as the global average and as a result, sea ice is melting rapidly. Scientists are racing to learn more about the changing Arctic climate system with some ecologists investigating the question, "How might the decline in sea ice affect Arctic organisms large and small?"

  • Megafires: Rare Occurrences or the New Normal?

    Over the past few years, the media has given a lot of attention to large wildfires known as "megafires". But are megafires a new phenomenon? In this Data Puzzle, students study the environmental conditions that lead to megafires and analyze a megafire frequency dataset to investigate the question, "How and why has the number of megafires changed over time?" Figure credit: DMCA.

  • Megadrought in the Colorado River Basin

    Much of the western United States is experiencing drought conditions. In this Data Puzzle, students analyze authentic climate data to construct explanatory models for the investigative question, "What is causing the megadrought in the Colorado River Basin?"

  • The Tipping Point

    Moss campion is a hearty tundra plant that lives over a wide range of latitudes from New Mexico all the way up to Alaska. For more than twenty years, ecologists have been tracking the vital rates (survival, growth, and reproduction) of moss campion from four study sites. In this Data Puzzle, students analyze a long-term dataset (moss campion reproduction rates and July temperatures) to investigate the question, "How is moss campion reproduction affected by temperature?" Questions like this one can give scientists insight into how these plants might be impacted by climate change. Image credit: Tracy Feldman.

  • Wind Farms of the Future

    Transitioning from fossil fuels to clean, renewable energy sources like wind is essential if the US is to reduce its carbon emissions. But where should new wind farms be constructed? In this Data Puzzle, students analyze surface roughness and wind speed data to construct an evidence-based explanation for the investigative question, "Where in the United States (lands and waters) should new wind turbines be constructed to generate the most energy?"
