A video micro-lecture that explains carbonate buffering in the ocean. It includes discussions on the changes in the chemical composition of the ocean caused by a higher concentration of dissolved CO2, ocean acidification and the resulting effect on ocean biota.
A reading that shows that climate change can be a selective pressure in natural selection. It explains how the selection of a character that provides an adaptive advantage in a changed environment, leads to the ‘evolutionary rescue’ of a species.

A micro-lecture that describes the vibrational modes of polyatomic molecules, how these modes determine whether the molecules are IR inactive or IR active and explains why most IR active polyatomic gas molecules are greenhouse gases.
A reading that discusses how chemical bonds in molecules respond to incident IR light and absorb IR energy during certain modes of vibration. The reading includes discussions on the vibrational modes of water vapor and carbon dioxide (CO2) molecules and explains why these gases act as greenhouse gases.
A classroom/laboratory activity that shows how to measure the rate of photosynthesis and its changes under different conditions including high concentrations of carbon dioxide, a potential contributor to climate change.
A reading that introduces hydrocarbons, fossil fuels, and the products of combustion of different hydrocarbons such as carbon dioxide- a greenhouse gas.
