I don't think a voluntary program meets the urgency of the situation.

The National Academy of Sciences went on to say that greenhouse gases are accumulating in the Earth's atmosphere as the result of human activities, causing surface air temperatures and sub-surface ocean temperatures to rise.

I thank you for the work you've done on it.

The Administration's inaction is hobbling our economy, and it is stealing growth opportunities from U.S. companies.

California has enacted legislation that will regulate tailpipe emissions of greenhouse gases.

The European Union just recently approved an emissions trading system.

According to a recent report from the National Oceanic and Atmospheric Administration (NOAA), nine of the warmest years have occurred since 1990.

The report states there is 'very high confidence,' defined as having more than 95 percent of observed changes which were principally caused by climate change, that climate change is already affecting living systems.

Greenhouse gases are accumulating in the Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise.

A large German insurance company has estimated that global warming could cost $300 billion annually by 2050 in weather damage, pollution, industrial and agricultural losses, and other expenses.

The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability.

Greenhouse gases are accumulating in the Earth's atmosphere as a result of human activities causing surface air temperatures and subsurface ocean temperatures to rise.

I’ve never seen anything like that ad, putting pictures of Saddam Hussein and Osama bin Laden next to a picture of a man who left three limbs on the battlefield. It is worse than disgraceful. It is reprehensible.

I think that is a very important point. The free enterprise system not only rewards but sometimes it punishes as well, as we are finding out in recent days.

And I am sure if one of the small operators was sitting at the table next to Mr. Bosak he would say, I cannot afford $1.2 million per aircraft, I simply cannot do that.

If we cannot get this issue moved forward, then it seems to me it is going to be extremely difficult to move the other parks forward.

It seems to me the free enterprise system indicates that if you want people to spend money, you have to have some kind of incentive for them to do so.

I would say that the folks that have not been paying fees for quite some time, if ever, should not be allowed to fly.

I think it is one of many ways to address this problem, but it has been our impression, either rightly or wrongly, that that aspect has been neglected to a large degree.

Well, let me just suggest to you on the alternative dispute resolution, I think everybody would go to the meeting recognizing that you are bound by court decisions.

Mr. Bosak, the air tour operators believe no matter how quiet an aircraft may be, any air tour that is audible will not satisfy the Park Service or environmental critics of the industry. What is your reaction to that allegation?

Thank you very much, and your full text, as well as the comments you wish included in the record, will be made a part of the record without objection.

Fifteen years is much too long to wait for a quieter park and a richer experience.

The reason why Mo Udall and I passed this bill is because being outside El Tobar Lodge was like being at the end of the runway at Phoenix Sky Harbor Airport.

My understanding is that with the proper incentives there is quiet technology out there that could be adopted by air tour operators if there were incentives for them to do so.
