This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.

This activity allows students to explore sea level rise. The experiment allows them to test whether land ice and/or sea ice contribute to sea level rise as they melt.

This interactive animation focuses on the carbon cycle and includes embedded videos and captioned images to provide greater clarification and detail of the cycle than would be available by a single static visual alone.

This demonstration shows how water absorbs more heat than air. The corollary that is made is that the oceans are absorbing a lot of the heat related to climate change. The video tutorial shows an engaging demonstration that teachers can do live in their classrooms as part of a larger lesson/discussion about global warming. The video itself also includes an animation of how greenhouse gases contribute to global warming and concludes by mentioning simple solutions for students.

This is an interactive table with a comprehensive list of 29 greenhouse gases, their molecular structures, a chart showing a time series of their atmospheric concentrations (at several sampling sites), their global warming potential (GWP) and their atmospheric lifetimes. References are given to the data sets that range from the mid-1990s to 2008.

Two simple experiments/demonstrations show the role of plants in mitigating the acidification caused when CO2 is dissolved in water.

This model of ocean-atmosphere interaction shows how carbon dioxide gas diffuses into water, causing the water to become more acidic. The video demonstration and instruction provide an explanation of the chemistry behind this change and the consequences of ocean acidification. The video also addresses a misconception about how ocean acidification affects shelled organisms.

This interactive follows carbon as it moves through various components of the carbon cycle.

This short investigation from Carbo Europe explores how temperature affects the solubility of carbon dioxide in water.

Here students use data from the NOAA carbon dioxide monitoring sites, such as Mauna Loa, to graph the Keeling Curve for themselves on large sheets of paper. Each group graphs one year, and the graphs are joined at the end to reveal the overall upward trend. The explanation describes the carbon cycle and how human activities are leading to the overall trend of rising carbon dioxide.
