Jim Sensenbrenner Quotes

The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.

I think that measuring with precision human activity on the climate is something very challenging to do and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see.

The fact is the planet is warming right now, and it is easier to blame it on some human activity rather than saying we should better understand the whole problem and recognize there are natural conditions that are impacting this, too.

I'm not going to argue with scientists how much human activity affects natural environment, including climate.

The debate is over. The scientific community has spoken in a virtually unanimous voice. Climate change is real. It is caused by human activity.

I'm absolutely convinced that the very small global warming we are experiencing is the result of natural causes. It's a cyclical phenomenon in the history of the Earth. The role of man is very small, almost negligible.

The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.

We're running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere... can handle before there is an environmental catastrophe.

The general trend in the last 4,000 years is that carbon dioxide and temperature have been moving against each other.

Human beings are definitely changing the planet, but how much impact they are having on climate, I don't know and I don't care.

The greenhouse effect of carbon-dioxide emissions does produce gentle warming if it is not counteracted by unpredictable natural phenomena, but it cannot be measured directly against the volume of such emissions.

Believe it or not, very little research has ever been funded to search for natural mechanisms of warming... it has simply been assumed that global warming is manmade. Climate change - it happens, with or without our help.

The climate has been changing since there was a climate.

Climate does fluctuate. It goes from hot to cold. We have ice ages.

When you analyze all the data, there is a warming trend according to science. But the jury is out on the degree of how much is manmade.

There is a majority of scientists that say that global carbon emissions by humans causes some changes in the climate.

It doesn't make sense to argue about how much global warming is caused by man - whether it's 5 percent or 50 percent.

For someone to say that someone's a skeptic or a climate denier about the climate changing, that's just nonsensical. We see that throughout history. We impact the climate by our activity. How much so is very difficult to determine with respect to our CO2 or carbon footprint, but we obviously do.

The climate is changing, but the question is how much - and to what extent human factors are contributing to that.

Climate change is real and humans do contribute to those changes.

The carbon dioxide concentration in the atmosphere is measured. It's uncontroversial. It's going up. We know that has a tendency to warm the atmosphere and we should be worried about that.

Few scientists now dispute that today's soaring levels of carbon dioxide and other gases in the atmosphere will cause global temperature averages to rise by as much as nine degrees Fahrenheit sometime after the year 2000.

Concentration of greenhouse gases, especially CO2, have increased substantially since the beginning of the industrial revolution. And the National Academy of Sciences indicates that the increase is due in large part to human activity.

When I was a boy in the 1930s, the carbon dioxide level was still below 300 parts per million. This year, it reached 382, the highest figure for hundreds of thousands of years.

...99 percent confident that the world really was getting warmer and that there was a high degree of probability that it was due to human-made greenhouse gases.
