The third conversation in this ongoing series, Author Promotes Lifestyle Changes in Global Warming Fight features writer and environmental activist Bill McKibben. He was one of the first non-scientists to raise concerns about Global Warming and the need to take positive actions.
| NewsHour wrote: | | His newest book, "Deep Economy," is a manifesto for attacking the problem locally. In it, he argues for creating a sustainable future by changing the way we eat, the way we use energy, and how we organize our communities. |

The fourth conversation in this ongoing series, Author Says Redirect Resources Against Climate Change features Danish author and statistician Bjorn Lomborg, Director of the Copenhagen Consensus Center.
| Quote: | Danish author and statistician Bjorn Lomborg discusses his proposal to redirect resources from a general fight against carbon emissions to specific efforts to mitigate the effects of climate change in vulnerable areas.
|
| Quote: | RAY SUAREZ: After two major reports this year detailed the problems and impact of global warming, there's growing attention to the question of what countries can do to slow climate change.
Tonight's guest looks at how we could adapt to a changing planet to blunt the impact of warming. He's Bjorn Lomborg, author of the upcoming book "Cool It: The Skeptical Environmentalist's Guide to Global Warming" and director of the Copenhagen Consensus Center. He joins us from Copenhagen this evening.
And, Professor, you've called spending several hundred billion dollars a year to combat global warming a bad deal for the people of the planet. How would you spend the money differently? |

The fifth conversation in this ongoing series, Energy Experts Debate Future Use of Coal features Steve Miller and Jeff Goodell.
Mr. Miller is President of Americans for Balanced Energy Choices, a trade group funded primarily by the coal-based electricity industry.
Mr. Goodell is the author of "Big Coal: The Dirty Secret Behind America's Energy Future."
| Quote: | RAY SUAREZ: Coal is a major and relatively cheap source of energy in this country, and its use worldwide is expected to grow. It powers everything, from steel production, kitchen appliances, and brings light to city skylines.
Nearly half our electricity comes from coal, and that figure is increasing, fueled by the roughly 150 new or proposed power plants on top of the more than 1,500 coal-fired plants already in operation.
But when coal is burned, it creates carbon dioxide, a greenhouse gas that traps heat and is a major contributor to global warming. These power plants produce about 40 percent of the nation's total carbon emissions.
Other major economic powers, including China and India, are also harnessing the power of coal and relying on burning more in the future. More than half the electricity consumed in those countries comes from coal.
To meet future demand here and abroad, President Bush and others have touted the idea of finding ways of making coal cleaner. |

The sixth conversation in this ongoing series, Physicist Searches for Alternative Fuel Technologies, features Professor Steven Chu, Director of the Lawrence Berkeley National Laboratory.
Professor Chu shared the 1997 Nobel Prize in physics for his work on using lasers to trap and cool atoms. He is a professor of physics and cellular and molecular biology at the University of California, Berkeley.
| Quote: | STEVEN CHU, Scientist: So if you say, "Wait until you're really sure," then it will be too late. In the last five or six years, I was following this as an interested citizen. And it became more and more apparent to me that the dangers, potential risks of climate change were looking like they're more and more likely, and that one really has to, as a scientist, as a responsible scientist, we really have to think of, what can you do to help with this problem?
SPENCER MICHELS: The Lawrence Berkeley lab has long been active in promoting energy conservation. The compact fluorescent light bulb was invented here, and scientists have been experimenting with ways to cut down energy use by electronically controlling how much light goes through windows. Air conditioning and heating due to inefficient windows account for 15 percent of all energy used in the U.S.
But Chu thought a more comprehensive effort was needed, including finding new energy sources, so he has harnessed independent-minded biologists, chemists, physicists, and engineers from the lab and from the Berkeley campus to work together, something that's rare in academia.
STEVEN CHU: Can we get the very best basic researchers to take this on as a challenge? Then you have the intellectual horsepower to actually get something going. And you can't do this -- the magnitude and scale of the problem is something you cannot do as an individual researcher. |

Greetings,
The seventh conversation in this ongoing series, Physicist Advocates Alternative Energy Research, features Martin I. Hoffert, Professor Emeritus of Physics at New York University.
Professor Hoffert led a team who "conducted what may be the first comprehensive study of non-carbon-dioxide-producing energy sources to evaluate how to stabilize the Earth’s climate while meeting the world’s energy needs." Scientists tackle the big question: what will it take to stop global warming?
| Quote: | RAY SUAREZ: Let's talk a little bit more about renewables, because even people who say that they're fans of renewables wonder if they can be scaled up, whether they can actually, at a cost that's relevant, produce one-third of the energy need that you're talking about.
MARTY HOFFERT: The biggest problem with renewables ultimately providing a major fraction of the energy market is the transmission and storage of the power. Renewable energies tend to be distributed and low in power density and intermittent. They're the very opposite of the centralized power that the electrical grids of the world have been designed for.
And so I would say that we really need to restructure the grids of countries, of our country and the world, to make them friendly for renewable energy. Eventually, I'm convinced that the costs of the conversion themselves are going to come down. Wind power already is cost-effective, and I believe eventually solar is going to have an even greater potential. |
Kindest regards,
Dragan Glas
