global warming and climate change

The new abundance of natural gas provides energy options for America, including clean electric power. Oil production has increased, reducing the dependence of the US on imported petroleum. Both benefits come with the challenge of managing the environmental impact of new oil and gas development in the US. This talk discusses the way shale gas and oil are created and produced, and the latest choices now available for generating energy in the United States.

What are fossil fuels? What is the greenhouse effect? How are the two related? Can we reduce our reliance on fossil fuels and lower the emission of greenhouse gases into the atmosphere? Wind and solar power can help lead the way. Learn how state-of-the-art science and engineering can be used to utilize more clean, green energy from both the wind and the sun, right out of thin air.

Warren Washington, a member of the Intergovernmental Panel on Climate Change and an internationally recognized expert on atmospheric science and climate research, describes the research that led to the 2007 Nobel Prize. Series: "Lawrence Berkeley National Laboratory " [Science] [Show ID: 28607]

Rapidly melting arctic ice, catastrophic hurricanes, devastating wildfires, and record-breaking drought—scientists agree that the climate is changing, that it’s human caused, and that it will undeniably be one of the most serious problems facing the world’s citizens for generations to come. They acknowledge that technologies to combat climate change do exist. How can we come together to address this challenge which has become a partisan political issue in the United States in a way it has not elsewhere in the world? Join UC Berkeley Professor Dan Kammen, an internationally recognized energy policy expert and Mr. Tom Steyer, business leader and investor, for a lively and timely conversation to understand where we are now, the solutions at hand, the barriers we face, and what must happen to "overcome the partisan divide" to speed the transition to a sustainable planet.

All of us contribute to the greenhouse gas emissions that are causing climate change. But there are ways to reduce our carbon emissions. How we travel, what we eat, what we consume and what we discard are just some of the factors that contribute to our carbon footprint. Louis S. Santiago, an assistant professor of physiological ecology at the University of California, Riverside, explains how we can measure our impact on our climate. He argues that we can all do something to reduce our carbon footprint. Series: "Earth 101: What You Need to Know About Life on our Planet" [Science] [Show ID: 24208]

Can we produce much of the energy we need from clean, renewable sources? Jeff Mirocha, atmospheric scientist and the technical leader of LLNL's wind energy research group, and Sonia Wharton, post-doctorate scholar in the Climate/Carbon Science Group, argue that wind energy can lead the way. Learn why the wind blows, where the winds blow the best, how energy can be generated from the wind, and how science and engineering can ensure a reliable and abundant supply of green, renewable energy to power our future.

LLNL scientist Dean Williams explores the evolution of climate models with from the mid 1970's to the present. Methods for testing climate models against a variety of benchmarks such as historical climate changes or seasonal changes are explained. Several key issues arising from global climate change are highlighted followed by suggestions for actions that will help limit carbon dioxide emissions.

Agriculture is a major force of global environmental change, and currently accounts for more global greenhouse gas release than transportation. With the demand for crops projected to double by 2050 University of Minnesota Professor David Tilman explores the impacts that increase will have in the decades to come, and how to manage this with proper planning and global management.

Hydrocarbon fuels come almost exclusively from underground. We burn the coal or oil to obtain energy - and for hundreds of years, we have then allowed the resulting carbon dioxide to simply enter the atmosphere. Ken Wedel, Tracy High School Earth Science teacher,explores the role that underground storage of carbon dioxide can play in helping avoid damaging climate change, and the scientific challenges that face us in trying to keep the atmospheric load of carbon dioxide from continuing to grow due to burning fossil fuels.

Our future health, happiness and economic well-being depends on producing plentiful, inexpensive, carbon-free energy that is available 24 hours/day, worldwide. Coal, oil and gas supply over 80% of the world's energy but cause pollution and add to global warming. Renewable energy, such as wind and solar, may not be able to supply enough energy. Ed Moses and the National Ignition Facility have an idea that could change everything-fusion energy-unlocking the force inside the nucleus of hydrogen that powers the sun and the stars. Learn what it will take for fusion power to become a reality in the next few decades. Series: "Lawrence Livermore National Lab Science on Saturday" [Science] [Show ID: 20233]

It is very likely that rising levels of greenhouse gases in the atmosphere resulting from human activity are increasing global temperatures and changing Earth's climate. Lawrence Livermore National Lab’s Karis MacFarlane explains about the carbon cycle, ways that forests and soils store carbon, and how carbon storage and loss from forests and soils might change with changes in climate and human activity.
