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.
In this worksheet-based activity, students review global visualizations of incoming sunlight and surface temperature and discuss seasonal change. Students use the visualizations to support inquiry on the differences in seasonal change in the Northern and Southern Hemispheres and how land and water absorb and release heat differently. The activity culminates in an argument about why one hemisphere experiences warmer summers although it receives less total solar energy.
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.
