With a fourth generation of nuclear power, you can have a technology that will burn more than 99 percent of the energy in the fuel. It would mean that you don't need to mine uranium for the next thousand years.
What makes tar sands particularly odious is that the energy you get out in the end, per unit carbon dioxide, is poor. It's equivalent to burning coal in your automobile.
Earth is warmer in 1988 than at any time in the history of instrumental measurements, The warming of a few degrees is going to take us to a world that is perhaps as different from today as the last ice age is from today.
On a per capita basis, Britain is responsible for more of the carbon dioxide now in the atmosphere than any other nation on Earth because it has been burning it from the dawn of the Industrial Revolution.
Consider the perverse effect cap and trade has on altruistic actions. Say you decide to buy a small, high-efficiency car. That reduces your emissions, but not your country's. Instead it allows somebody else to buy a bigger S.U.V. - because the total emissions are set by the cap.
They're a lot of fun to perform with. They're good guys to work with. They're helpful to work with. Any time you can work with a professional group, it's helpful.
Injection of environmental and political perspectives in midstream of the science discussion cannot help the process of inquiry. I believe that persons with relevant scientific expertise should concentrate, with pride, on cool objective analysis, providing information to the public and decision-makers when it is found, but leaving the moral implications for later common consideration, or at most for summary inferential discussion.
It is an important study that increases our confidence that there is a link between global warming and intense tropical storms.
I think this is a more optimistic assessment of the chances for keeping climate change moderate in the next 50 years, and the way to do that is to focus on stopping the growth of several gases, ... Global Warming in the 21st Century: An Alternative Scenario.
The area below the proposed plat has experienced numerous slides that have resulted in residential property damage.
To be playing in a threesome with Neil Armstrong and Clint Eastwood was pretty incredible, ... For Peggy and I to be part of that was pretty heady stuff.
We can't afford to wait another 10 years.
Tipping points are so dangerous because if you pass them, the climate is out of humanity's control: if an ice sheet disintegrates and starts to slide into the ocean there's nothing we can do about that.
You have no time to do the science if you're talking to the media.
