A Quote by Saul Perlmutter

This new understanding of processes on Europa would not have been possible without the foundation of the last 20 years of observations over Earth's ice sheets and floating ice shelves.

Ice cores, which are long cylinders scientists extract from glaciers, ice sheets or ice caps, contain gas bubbles, pollen, dust particles, or chemical isotopes that give scientists clues about what Earth's temperature and atmosphere were like when the ice caps first formed.

It does seem that the sea ice is returning to 'average' after the record lows of 2007 and 2008. There has been a definite recovery trend since then, so far from being a progression towards ice free summers it seems that it was a temporary dip. The recent observations do make the 2007 projections that the region would be ice free by 2013 look very unrealistic. Given what is happening only the foolish would look many years into the future and predict ice free summers now.

I skated in ice shows all over Europe and South Africa for 20 years. I love to ice skate.

Permafrost in the soil [is melting], in the boreal and arctic areas in the world, and, probably even more alarming in the last six or eight months, the data on what is happening to the ice shelves in Greenland and the west Antarctic has begun to cause people to radically reassess the earlier conviction that those ice shelves were stable on a kind of century-long time scale.

It's very clear that global climate change is occurring on earth, but it's also been very clear that that has always happened on earth. We've always had a changing climate on earth. We all know about ice ages. We know when our continent was covered with ice sheets. We know glaciers come and they go. It puzzles me that people forget that.

Heidi Hammel

Ice shelves in general have episodic carvings and there can be large icebergs breaking off - I'm talking 100km or 200km long - every 10 or 20 or 50 years.

We have to, in the next ten years, begin to decrease the rate of carbon dioxide emissions and then flatten it out. If that doesn't happen in ten years, we're going to be passing certain tipping points. If the ice sheets begin to disintegrate, what can you do about it? You can't tie a rope around an ice sheet.

James Hansen

Certain signs, some of them visible to the layman as well as the scientist, indicate that we have been watching an ice age approach for some time without realizing what we are seeing... Scientists predict that it will cause great snows which the world has not seen since the last ice age thousands of years ago.

Betty Friedan

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

James Hansen

The Earth has been lawned with life for something over 3.5 billion years. That's a span of time great enough to encompass some honest-to-goodness catastrophe. For example, 700 million years ago, Earth underwent a planet-wide deep freeze, with ice covering the oceans from the poles to the equator.

Seth Shostak

"Ice" came in when my friends would say "cold as ice" -- if you could rap and battle people you'd say "Dude, that was ice cold." It had nothing to do with jewelry. Back then, it was like "Your cold, dawg." "Vanilla Ice -- that's cold."

Vanilla Ice

The ice sheets seem to be shrinking 100 years ahead of schedule.

Richard Alley

The climate of this planet has been changing since God put the planet here. It will always change, and the warming in the last 10 years is not much difference than the warming we saw in the 1930s and other decades. And, lets not forget we are at the end of the ice age in which ice covered most of North America and Northern Europe.

James Spann

Black ice is the smoothest naturally occuring ice there is, as if nature were condescending to art. ... Black ice is an act of nature as elusive as grace, and far more rare. ... I have never skated on black ice, but perhaps my children will. They'll know it, at least, when it appears: that the earth can stretch smooth and unbroken like grace, and they'll know as they know my voice that they were meant to have their share.
