A Quote by Andrew Revkin

When I wrote a long story about the retreat of sea ice, I made clear it could go the other way for a while, and that doesn't mean we don't know that a warmer world will have less sea ice. It just means there's a lot of variability and people can pay too much attention to the big swings in one direction or the other.
On land off an ice covered sea the traveler can, for example, detect the presence of open water, simply because it reflects less light than land or ice. The open sea's telltale sign is thus a darkness on the underside of the clouds.
Some 3 million years ago, when the earth was a little more than 3°C warmer than preindustrial levels (about 2.2°C warmer than today), Antarctica had far less ice and sea levels were a stunning 25 meters higher than today. If we stay on our current emissions path, the planet will almost certainly be that warm by the century's end.
Much of the attention on oceans has portrayed oceans as a villain. Warm water strengthened Hurricane Katrina that pounded Louisiana. Rising sea level will flood islands and coastal areas. Or, we're talking about new opportunities like a new shipping lane in the Arctic because of melting sea ice. These may be the obvious problems, but they're probably not the biggest ones.
Are we likely to see rising sea-levels? Not in our lifetimes or hose of our grandchildren. It is not even clear that sea-levels have risen at all. As so often in this domain, there is conflicting evidence. The melting of polar or sea ice has no direct effect.
Ice in the West Antarctic and over Greenland, i.e., ice that's over a rock at the moment, that will raise the level of the sea as it slides into the ocean, putting at risk everyone and everything that lives on the coasts, and that includes an enormous percentage of the world's people.
I started traveling in the Arctic in 1991, so I experienced the ice in winter and spring. The seasonal sea ice, it has a long season. It starts in September and ends in June.
I don't really look at stats or whatever. You see them on the big screen. But other than that, I don't pay too much attention to it. I did know about my dad's home run total. Other than that, I don't like to know. It's pointless. Whether you know or don't know, you don't want to think about it. You just want to go out and play the game.
ice contains no future , just the past, sealed away. As if they're alive, everything in the world is sealed up inside, clear and distinct. Ice can preserve all kinds of things that way- cleanly, clearly. That's the essence of ice, the role it plays.
Saving Greenland is both a metaphor and a precondition for saving civilization. If its ice sheet melts, sea levels will rise 23 feet. Hundreds of coastal cities will be abandoned. The rice growing river deltas of Asia will be under water. There will be hundreds of millions of rising-sea refuges. The word that comes to mind is chaos. If we cannot mobilize to save the Greenland ice sheet; we probably cannot save civilization as we know it.
People travel and hunt on the sea ice - in Alaska, they hunt in skin boats for bowhead whales; in Greenland, they hunt with dogsleds. The ice is their highway. The ice is also the ecosystem in which marine mammals and terrestrial animals such as polar bears exist.
When I made '101 Reykjavik,' people talked about 'Almodovar on ice.' When I made 'The Sea,' people referenced Bergman.
When we moved from 'Ice Age' to 'Ice Age 2,' we were really stuck; a story didn't just organically emerge. While I'm very proud of 'Ice Age 2,' from a storytelling sense, it's a very thin story.
What's your story? It's all in the telling. Stories are compasses and architecture; we navigate by them, and to be without a story is to be lost in the vastness of world that spreads in all directions like arctic tundra or sea ice. To love someone is to put yourself in their place, we say, which is to put yourself in their story, or figure out how to tell yourself their story. Which means that a place is a story, and stories are geography, and empathy is first of all an act of imagination, a storyteller's art, and then a way of traveling from here to there.
For me the most important issue is climate change because it in some ways trumps every other issue. Everything else we care about falls by the wayside if the Greenland ice shelf falls into the sea. And if suddenly sea levels rise 21 feet, everything we hold near and dear ceases to exist.
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.
I have an unexplainable belief that I will never cause harm or be harmed while at sea. Because of this, I feel secure at sea: I feel secure in the ice, I feel secure in the storms, and I feel secure in confrontations.
