Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.

The five warmest years over the last century occurred in the last eight years.

Adding CO2 to the air is like throwing another blanket on the bed.

As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species.

Because cap and trade is enforced through the selling and trading of permits, it actually perpetuates the pollution it is supposed to eliminate.

Climate change is analogous to Lincoln and slavery or Churchill and Nazism: it's not the kind of thing where you can compromise.

Coal is responsible for as much atmospheric carbon dioxide as other fossil fuels combined and it still has far greater reserves. We must stop using it.

Global warming isn't a prediction. It is happening.

I have been described as the grandfather of climate change. In fact, I am just a grandfather and I do not want my grandchildren to say that grandpa understood what was happening but didn't make it clear.

I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.

If your child gets asthma, the fossil fuel industry doesn't pay. Or if there's a natural disaster, the bill is paid by the taxpayer, not the fossil fuel company.

It's as certain that as long as fossil fuels are the cheapest energy, we will just keep burning them.

Jail threats did not dissuade Martin Luther King - and intergenerational justice is a moral issue of comparable magnitude to civil rights.

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.

Several times in Earth's history, rapid global warming occurred, apparently spurred by amplifying feedbacks. In each case, more than half of plant and animal species became extinct. New species came into being over tens and hundreds of thousands of years. But these are time scales and generations that we cannot imagine.

Talking nice about sun and wind and green jobs is just greenwash.

The United States did not sign Kyoto, yet its emissions are not that different from the countries that did sign it.

The fact is fossil fuel carbon will stay in the surface climate system for millennia.

The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.

We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life.

We need to send a message to Congress and the president that we want them to take the actions that are needed to preserve climate for young people and future generations and all life on the planet.

What has become clear from the science is that we cannot burn all of the fossil fuels without creating a very different planet.

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.

What we are doing to the future of our children, and the other species on the planet, is a clear moral issue.

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.

You can't tie a rope around the ice sheet. You can't build a wall around the ice sheets.

You can't turn on your television without seeing these advertisements about clean coal, clean tar sands and the claim that there's more jobs associated with fossil fuels than other industries. That's of course not true. But they're hammering that into the voters' heads.

We are on the precipice of climate system tipping points beyond which there is no redemption.

Interference with communications of science to the public has been greater during the current administration than at any time in my career.

Being at NASA and having the access to both computing capability and satellite observation capability is kind of the ideal research situation to try to understand global climate change.

The urgency derives from the nearness of climate tipping points.

The individual organs follow the same pattern as the whole organism, i.e. they have their period of growth, of stationary, maximum activity and then of aging decline.

I take great pride in having been able to overcome the Asian financial crisis and seeking the opportunities available to bring about an unprecedented growth in the economy.

Conformity is the jailer of freedom and the enemy of growth.

Genius is not a possession of the limited few, but exists in some degree in everyone. Where there is natural growth, a full and free play of faculties, genius will manifest itself.

The investor of today does not profit from yesterday's growth.

Promoting job creation and economic growth in the Hudson Valley is one of my top priorities in Congress.

We will see the increasingly rapid rate of growth we've already been seeing in Colorado continue.

The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

We have stabilized our economy. We took over a very sick economy, and we were hemorrhaging 750,000 jobs a month. We have stopped the hemorrhaging. In fact, we had 140,000 job growth last month. And that's what I call progress.

We got to know the competition very well. In the '50s popcorn made a big growth in sales. Our main push was to produce the best quality and sell in quality retail outlets.

Happiness, contentment, the health and growth of the soul, depend, as men have proved over and over again, upon some simple issue, some single turning of the soul.

It's hard to find a way forward. When you're 18 it happens in huge chunks every day, but after 20 years, growth is much more costly.

I think that obstacles lead to growth and ultimately, the most learning I've done in my life is between jobs.

Well, WorldCom's growth exploded in the Clinton years, there's no question, there's no disputing that.

Growth is a painful process.

The organizational architecture is really that a centipede walks on hundred legs and one or two don't count. So if I lose one or two legs, the process will go on, the organization will go on, the growth will go on.

Modern techniques have torn down state frontiers, both economical and intellectual. The growth of means of transport has created a world market and an opportunity for division of labor embracing all the developed and most of the undeveloped states.
