Climate scientist Michael MacCracken explores some of the scientific, legal, and ethical implications of "geo-engineering" options that have been proposed by some people to address global climate change.
CalNex—an intense data collection campaign to characterize the complicated interactions of air quality and climate over California—used an array of instruments and platforms this spring for a close look at greenhouse gases and pollutants.
Global climate models project that near the end of the 21st century, average surface temperature over most of Earth’s surface will be several degrees warmer than today, mainly due to rising levels of greenhouse gases in the atmosphere.
Carbon dioxide is everywhere: in the air, rising from cracks in the ocean floor, and in your soda can. Now it's showing up in the news! Find out why carbon dioxide is such a hot topic, and why it's going to be around for a long, long time.
This video features the story of a multi-generational family-run dairy business in Oregon that aspires for sustainability while serving a local market, conserving energy, and reducing greenhouse gas emissions by burning waste from its dairy cows.
This is a simulation that illustrates how temperature will be affected by global CO2 emission trajectories. It addresses the issue that even if global emissions begin to decrease, the atmospheric concentration of CO2 will continue to increase, resulting in increased global temperatures.
This is the ninth and final lesson in a series of lessons about climate change. This lesson focuses on the various activities that humans can do to mitigate the effects of climate change. This includes information on current and predicted CO2 emission scenarios across the globe, alternative energy sources, and how people are currently responding to climate change. Importantly, this lesson is motivating in showing students that they can make a difference.
