A knowledgeable and courageous U.S. president could help enormously in leading the world's nations toward saving the climate.

Calculating how much carbon is absorbed by which forests and farms is a tricky task, especially when politicians do it.

Your paradigm is so intrinsic to your mental process that you are hardly aware of its existence, until you try to communicate with someone with a different paradigm.

A grand jury hears only one side - that of the prosecutor.

Denmark, the Netherlands and Germany have detailed plans to cut their greenhouse emissions by 20 to 50 percent.

Everyone except the far right wing of the Republican Party realizes that oil, gas and coal burning are the main activities that have sent the climate into bigger floods, droughts, hurricanes, and El Ninos.

There have been high crimes and misdemeanors, but they have been committed by the special prosecutor and the Congress, not the president.

Glaciers are almost gone from Glacier National Park.

I spent my time trying to understand grand jury procedure - a topic about which I never before had the slightest interest.

George W. cares as much about climate change as you would expect from a Texas oilman.

Scientists worldwide agree that the reduction needed to stabilize the climate is actually more like 80 percent.

You should issue demerits for tree cutting or the destruction of humus.

You may be able to fool the voters, but not the atmosphere.

Once again I stopped listening to the news this week.

The climate continues to deteriorate.

The European nations take climate change very seriously.

In 1994 the U.S. Court of Appeals decided in the case of Oliver North to permit the release of grand jury evidence, because it had already been so thoroughly leaked.

The grand jury's job is not to weigh the evidence from both sides; it is only to decide whether there is enough evidence on one side to bring a person to trial.

What Clinton did with Lewinsky was despicable but was no threat to the nation. That he lied about it repeatedly and to the public is a reason for us to cease to trust him and for him to resign.

The latest scientific assessment has almost doubled the predicted rate of warming if no changes are made.

A knowledgeable and courageous U.S. president could help enormously in leading the world's nations toward saving the climate.

At town meetings, you can see the shy folks, the ones who have trouble sounding off in public, leaning against the back wall or bending over their knitting. On talk radio, those people are invisible, but they're there. It's a mistake to think that the blowhards who call in speak for the nation.

Before they got vengeful, conservatives had some useful points to make about welfare. Government 'help' is too often guilt-assuaging gesture. It creates layers of wasteful bureaucracy. Too much help of the wrong sort creates a culture of dependency that swamps our ability to provide.

Biodiversity can't be maintained by protecting a few species in a zoo, or by preserving greenbelts or national parks. To function properly, nature needs more room than that. It can maintain itself, however, without human expense, without zookeepers, park rangers, foresters or gene banks. All it needs is to be left alone.

Both the United States and the world economy have already reached - and surpassed - their sustainable physical limits. Ground water is being drawn down, soils eroded, forests cut faster than they grow, fish caught faster than they reproduce, non-renewable fossil fuels burnt without developing substitutes.

Corporate responsibility extends not only to the customers, the resources and the workers of the present, but also to those of the future.

Ending poverty calls for humility, honesty, freedom from ideology and refusal to accept cruel simplicities about anyone's human potential. It requires listening to the wisdom and cutting the nonsense from both the Right and the Left.

Every policy is shaped by two forces: background analysis and foreground politics. The political forces are loud, self-serving and, in the case of energy policy, well known.

Growth is a stupid goal. So, by the way, is no-growth.

I know that war and mayhem run in our blood. I refuse to believe that they must dominate our lives. We humans are animals, too, but animals with amazing powers of rationality, morality, society. We can use our strength and courage not to savage each other, but to defend our highest purposes.

I'm a talk-show junkie. I'd rather listen to real folks stumbling to express their own thoughts than to polished puppets reading what others have written.

If we emit massive quantities of untested chemicals into the environment, some of them are bound to end up in places that surprise us, doing things that endanger us.

It's a fair guess that at the rate we're destroying habitat, especially but not exclusively in the tropics, we're pushing to extinction about one species every hour. That doesn't count the species whose populations are being reduced so greatly that diversity within the population is essentially gone.

Like the other great revolutions, an environmental revolution will require sacrifices and lead to enormous gains. It, too, will change the face of the land and human institutions, hierarchies, self-definitions, cultures. It will take centuries. If it happens. There is no guarantee, of course.

No expectations, no tension between goals and performance, no outrage, resolve or intention, no action, no results. There's only one way to get a government - and a nation - to stop drifting to low performance. That's to wake up and insist on higher standards.

No one wants growth, constant expansion, physical swelling. Growth is not a human value; it's a means to the ends of sufficiency and security. Once we have enough, no one wants more, unless it is sold to us as a cheap substitute for something else, something non-material.

Recession-resistant development produces things people need. Unsustainable growth churns out tinsel products that consumers have to be seduced into buying - until times get tough, when they quickly give them up.

Smart development builds on a region's own skills, resources and local businesses. Dumb growth invites a big corporation in, surrenders control and profits to a distant headquarters, undercuts local manufacturers, and risks layoffs without warning.

Smart development invests in insulation, efficient cars, and ever-renewed sources of energy. Dumb growth crashes around looking for more oil.

Social services, not wealth per se, seem to be the key to lower birth rates. The Chinese, although among the poorest peoples of the world, have brought their fertility rate down to 2.4, partly by social coercion, but mostly by broadly available education, health care and family planning.

Some call-in moderators are neutral and courteous. Then there's Rush Limbaugh, who is funny and pompous and a scapegoater and hatemonger. His popularity could cause you to draw some terrible conclusions about the state of mind of the American people. It helps to remember that Bill Cosby is popular, too.

The actions of my government are not bearable. They devastate our natural resources and deprive our people. The politicians speak piously while practicing greed and divisiveness. They care nothing for the nation. I want to do more than withdraw my support. I want to tar and feather them.

The human world is a long way from meeting the needs of the present, and it is borrowing massively from the future - not only by piling up money debt, but also by degrading the resources from which all real wealth ultimately comes.

The kind of support the down-and-out need is the kind we have always refused them, the kind that would mean engaging with them not as objects of contempt, but as fellow human beings.

There is hardly a place on Earth where people do not log, pave, spray, drain, flood, graze, fish, plow, burn, drill, spill or dump. There is no life zone, with the possible exception of the deep ocean, that we are not degrading.

We don't need bigger cars or fancier clothes. We need self-respect, identity, community, love, variety, beauty, challenge and a purpose in living that is greater than material accumulation.

We don't need new laws that can be used by organizations with deep pockets and the ability to deduct legal expenses as a cost of doing business to intimidate individuals or organizations that voice legitimate concerns.

We have come to expect campaigns to be mean and stupid and politicians to be unresponsive, self-seeking and for sale to the highest bidder. We make jokes about our vice president, and all we ask of a president is that he be likeable. We seem to have given up on the Pentagon's corrupt use of our tax dollars.

We have witnessed Chernobyl, Bhopal, Challenger, Seveso, Amoco Cadiz, Three Mile Island and have still not wakened from our fantasy that large organizations can carry out complex technologies on a huge scale with total perfection.
