George W. Bush Quotes

So far the earth has warmed about a degree Fahrenheit globally averaged. That doesn't seem like an enormous amount but it's unlike what we would have expected twenty years ago.

In Australia, average temperatures have risen almost one degree since 1910, and each decade since the 1940s has been warmer than the one before. That warming is real. Its consequences are real. And it will change our lives in real and practical ways.

The average global temperature has increased by about 0.8 degrees Celsius since 1880, with two-thirds of the warming occurring since 1975.

...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.

The ten hottest years in the atmospheric record, going back only 160 years, have been in the last eleven years.

The important point there is that when people talk about a mean temperature rise of say two, three or four degrees that's a sort of global average which really is a signature of large scale change in climatic patterns.

Our analysis shows that, for the extreme hot weather of the recent past, there is virtually no explanation other than climate change. The deadly European heat wave of 2003, the fiery Russian heat wave of 2010 and catastrophic droughts in Texas and Oklahoma last year [2011] can each be attributed to climate change. The odds that natural variability created these extremes are minuscule, vanishingly small. To count on those odds would be like quitting your job and playing the lottery every morning to pay the bills.

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.

The world has not warmed up very much since the millennium.

I don't think anybody would dispute that we're seeing a warming of the Earth.

The science is not settled …. We may in fact be going into a cooling period.

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 believe the Earth is warming.

If anything, I would like to see the climate change happen, so the science could be proved right, regardless of the consequences. This isn’t being political, it is being selfish.

We've had these bursts of cool years here or there but that's not change. That's a trend. You only hope that this could be the beginning of true change.

global warming. every day i leave my house and think, "was it this hot last year?" the heat this summer here in LA and in most of the US has been unbearable. i can't remember another time when it was 105 degrees fahrenheit out here (40.5 celsius), and that's the kind of weather we've been having pretty much every day.

We see something change in our climate and we blame ourselves ... I don't think we understand what happens. We can watch it happen on the (climate) models, we know it happens, but we don't know for sure how it happens.

It has become very difficult for anyone to argue that observed global warming is natural variability. We have good reason for being able to say that the world will be warmer by about a quarter of a degree in the next decade. It's the same reason we had 10 years ago when we said that the 1990s would be warmer than the 1980s: The planet is out of equilibrium.

Is global warming new? I don't know. When I was young I remember the sun being hot.

The evidence for human-made climate change is overwhelming.

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.

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.

Imagine what our planet would look like with an increase in temperature of two degrees or four degrees, given that at 0.8 degrees we already have serious problems in the world.

Every day, the temperature of Sol's surface increases by five billionths of a degree, a change of no consequence for thousands of millennia to come. But a few hundred million years from now, barring a fix by our descendants, this relentless heating will substantially change Earth's biosphere in ways that might not be survivable for us.

Clearly, there have been changes in the climate.
