This short video reviews how nations and individuals on Earth can work together to reduce the emission of CO2. It discusses strategies to reduce greenhouse gas emissions (energy conservation, renewable energies, change in energy use) and the role that government can play in this process.

This video on phenology of plants and bees discusses the MODIS satellite finding that springtime greening is happening one half-day earlier each year and correlates this to bee pollination field studies.

A colorful graphic that depicts the risks to the environment from different degrees of temperature rise. This graphic addresses how risks change as global mean temperature increases.

This video describes the effect of a warming climate on the tundra biome and specifically the impacts of changing climate on the Rocky Mountain Pika, a small rodent that struggles with summer heat.

In this activity, students look at how much solar energy is generated by photovoltaic panels on rooftops or exposed ground locations at installations around the United States. They explore three different websites that monitor and report solar energy production from panels at many different locations. Next, they examine data from a single location, as well as compare data from two different locations. Lastly, they consider how much of a school's or home's energy needs could be supplied by solar power.

An interactive that illustrates the relationships between the axial tilt of the Earth, latitude, and temperature. Several data sets (including temperature, Sun-Earth distance, daylight hours) can be collected using this interactive.

This brief, hands-on activity illustrates the different heating capacities of soil and water in order to understand why places near the sea have a more moderate climate than those inland.

This video describes the work of scientists who are studying the precise combination of trees that would be most effective in reducing the level of greenhouse gases in the air around Syracuse, NY. This is a pilot study that will serve as a model for other urban areas.

This poster, viewable online, highlights some of the impacts of a global-average temperature rise of 2 degrees C above the pre-industrial age climate.

This interactive video series reviews global warming by recognizing the problem, addressing the sources and impacts, and weighing the options. It is a six-chapter series. Experts from different countries weigh in and answer some critical questions, including what countries have resources and the perspectives necessary to reach a consensus on handling the next steps and the economic costs involved.
