In this self-paced tutorial, learners analyze data to understand the relative influence of solar variability on today's climate to determine whether changes in incoming solar radiation can explain all or part of the warming trend we have seen in... (View More)

In this self-paced tutorial, learners trace the feedbacks in the Earth system that are responsible for the Arctic's sensitivity to global climate change impacts. Both graphical data sets and scientific visualizations are evaluated for evidence for... (View More)

This self-paced tutorial explores the importance of engineering solutions to the management of climate change by brainstorming ways to remove CO² from the atmosphere and store it in a form that does not promote global warming. The module also... (View More)

Since the Industrial Revolution, atmospheric carbon dioxide concentration has risen from ~280ppm (parts per million by volume) to ~390ppm in 2010. The rate of increase for the last decade (2001-2010) has been 2.04ppm/yr, more than double the rate... (View More)

In this problem-based learning unit, learners analyze the role of condensation trails from jets, or contrails, and their role in climate change. Contrails are thin ice clouds that form from the burning of jet fuel and release of water vapor. The... (View More)

In this problem-based learning unit, learners examine the causes and impacts of dust transported through the atmosphere. An estimated two billion tons of dust is emitted by the Earth annually. Scientists are becoming increasingly interested in the... (View More)

In this problem-based learning activity, learners explore the significance of sunspots on the Earth's climate. Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. During... (View More)

In this problem-based learning unit, learners explore the possibilities of sustainable energy, and engage in a project to provide electricity for their city using alternative energy sources. Instructions to access NASA data are provided along with... (View More)

Temperature increases associated with global climate change have led to concerns that infectious diseases common in warmer tropical and subtropical climates may become more common in warming middle altitudes. In this problem-based learning module,... (View More)

In this problem-based learning module, learners study phytoplankton blooms along the U.S. coast. Phytoplankton form the basis of the marine food web, regulate carbon in the atmosphere, and are responsible for half of the photosynthesis that takes... (View More)
