Alternative Renewable Energy Sources for Earth: Where in the world will our energy come from? What would it take for the world to get away from fossil fuels and switch over to renewable energy? It takes more than willingness to buy a Prius or to install solar panels on your roof. If we want to use wind solar thermal, solar electric, biomass, hydroelectric and geothermal energy it will take a lot of planning, and willingness on the part of governments and industry. It takes R&D investment, a favorable price per unit of energy to get anyone to produce alternative energy, and plenty of resources to create those energy sources.

Predicting Climate Change: Meeting the challenge of predicting climate change involves collaboration of many different types of scientists. The effort will contribute to the success of projecting the impacts of global warming, accurately predicting the El Niño phenomena, and providing improved weather forecasts. This talk will discuss fundamentals and challenges associate with building climate models, and how new satellites, instruments, and supercomputers are combining to improve climate models and their predictive capabilities.

The International Geophysical Year: In 1952, a group of American scientists decided the world scientific community should undertake a third International Polar Year (IPY), building on those carried out in 1882/1883 and 1932/1933. The idea of launching an artificial scientific satellite during the IPY took hold and the event was renamed the International Geophysical Year, or IGY. It took place from 1957/1958. The IGY's Earth satellite program led to the Soviet Sputnik surprise and the space race. It also led to the transformation of JPL from an Army weapons laboratory to NASA's planetary exploration center. These events revolutionized American science, creating the new field of planetary science while enabling new discoveries in areas as diverse as geophysics and climate science.

Your Carbon Footprint and the Greenhouse Effect: Carbon dioxide is the primary greenhouse gas released into the atmosphere by fossil fuel combustion and other human activities. The year 2005 saw atmospheric carbon dioxide climb to its highest level in the last 500,000 years - raising concerns about increased greenhouse gases Earth's climate to change. NASA's future Orbiting Carbon Observatory mission will collect precise global measurements of carbon dioxide in Earth's atmosphere and revolutionize our understanding of the global carbon cycle.

Looking at Clouds from Both Sides: Clouds are responsible for transporting water from the air to the ground, and responsible for transporting water from one region of the globe to another. They also influence the changes of the solar and thermal energy within our atmosphere, as well as between the Earth's surface, hydrosphere, biosphere, and space. Dr. Graeme Stephens, principal investigator for CloudSat, speaks about the mission and its significance.
