Add a new item to the list of things that have migrated in response to climate change: the latitude where hurricanes reach their maximum intensity. The shift was accompanied by increasing vertical wind shear near the equator.
It’s finally here! Yesterday, scientists from the National Snow and Ice Data Center announced the ultimate sign of spring: Arctic sea ice reached its winter peak on March 21, 2014, and the annual melt season is underway.
Although you might have a hard time convincing residents of the eastern United States, Scandinavia, and Russia (outside of Sochi, anyway), January’s global average surface temperature balanced out as the fourth warmest in the historical record.
Persistent cold temperatures in the Midwest this winter almost completely frozen over many of the Great Lakes. The Great Lakes Environmental Research Laboratory (GLERL) reported that 88 percent of the Great Lakes were frozen as of mid-February.
Activity in which students investigate what causes the seasons by doing a series of kinesthetic modeling activities and readings. Activity includes educator background information about how to address common misconceptions about the seasons with students.
This three-part, hands-on investigation explores how sunlight's angle of incidence at Earth's surface impacts the amount of solar radiation received in a given area. The activity is supported by PowerPoint slides and background information.
In this classroom activity, students analyze visualizations and graphs that show the annual cycle of plant growth and decline. They explore patterns of annual change for the globe and several regions in each hemisphere that have different land cover and will match graphs that show annual green-up and green-down patterns with a specific land cover type.
In this hands-on lesson, students measure the effect of distance and inclination on the amount of heat felt by an object and apply this experiment to building an understanding of seasonality. In Part 1, the students set up two thermometers at different distances from a light bulb and record their temperatures to determine how distance from a heat source affects temperature.
