Nansen Corrects Sea Ice Data – Sea Ice Extent Now Greater, Near Normal for Most of April/May

Interest in sea ice extent continues to run high, but there remains differences between different groups such as NSIDC and Cryosphere Today, which have both been plagued with SSMI sensor problems from the DMSP F13 satellite. NANSEN may have had the same issues with SSMI/F13, and if they did, they seem to have gotten them under control, possibly by switching to SSSMI/F17 as NSIDC did.

For example here is a page that NANSEN maintains that shows the differences between the newer AMSRE (that JAXA uses) and the SSMI. One of the images is an AMSR minus SSMI, and it looks like the two different satellites/sensors are in pretty good agreement, with areas along the ice edge (where ice/water boundaries are rapidly changing) showing noise differences where you would expect them to.

The sick mind of environmentalism

The right to have children should be a marketable commodity, bought and traded by individuals but absolutely limited by the state.Kenneth Boulding, originator of the “Spaceship Earth”
concept (as quoted by William Tucker in Progress and Privilege, 1982).

We have wished, we ecofreaks, for a disaster or for a social change to come and bomb us into Stone Age, where we might live like Indians in our valley, with our localism, our appropriate technology, our gardens, our homemade religion—guilt-free at last!
Stewart Brand (writing in the Whole Earth Catalogue).

Free Enterprise really means rich people get richer. They have the freedom to exploit and psychologically rape their fellow human beings in the process…. Capitalism is destroying the earth.
Helen Caldicott, Union of Concerned Scientists.

We must make this an insecure and inhospitable place for capitalists and their projects…. We must reclaim the roads and plowed land, halt dam construction, tear down existing dams, free shackled rivers and return to wilderness millions of tens of millions of acres of presently settled land.
David Foreman, Earth First!

Everything we have developed over the last 100 years should be destroyed.Pentti Linkola

If you ask me, it’d be a little short of disastrous for us to discover a source of clean, cheap, abundant energy because of what we would do with it. We ought to be looking for energy sources that are adequate for our needs, but that won’t give us the excesses of concentrated energy with which we could do mischief to the earth or to each other.
Amory Lovins in The Mother Earth–Plowboy Interview, Nov/Dec 1977, p.22

The only real good technology is no technology at all. Technology is taxation without representation, imposed by our elitist species (man) upon the rest of the natural world.John Shuttleworth

What we’ve got to do in energy conservation is try to ride the global warming issue. Even if the theory of global warming is wrong, to have approached global warming as if it is real means energy conservation, so we will be doing the right thing anyway in terms of economic policy and environmental policy.Timothy Wirth, former U.S. Senator (D-Colorado)
I suspect that eradicating smallpox was wrong. It played an important part in balancing ecosystems.
John Davis, editor of Earth First! Journal
Human beings, as a species, have no more value than slugs.John Davis, editor of Earth First! Journal
The extinction of the human species may not only be inevitable but a good thing....This is not to say that the rise of human civilization is insignificant, but there is no way of showing that it will be much help to the world in the long run.Economist editorial
We advocate biodiversity for biodiversity’s sake. It may take our extinction to set things straight.David Foreman, Earth First!
Phasing out the human race will solve every problem on earth, social and environmental.
Dave Forman, Founder of Earth First!

If radical environmentalists were to invent a disease to bring human populations back to sanity, it would probably be something like AIDS.Earth First! Newsletter
Human happiness, and certainly human fecundity, is not as important as a wild and healthy planets…Some of us can only hope for the right virus to come along.David Graber, biologist, National Park Service
The collective needs of non-human species must take precedence over the needs and desires of humans.Dr. Reed F. Noss, The Wildlands Project

If I were reincarnated, I would wish to be returned to Earth as a killer virus to lower human population levels.Prince Phillip, World Wildlife Fund

Cannibalism is a “radical but realistic solution to the problem of overpopulation.”Lyall Watson, The Financial Times, 15 July 1995

Poverty For “Those People”We, in the green movement, aspire to a cultural model in which killing a forest will be considered more contemptible and more criminal than the sale of 6-year-old children to Asian brothels.Carl Amery

Every time you turn on an electric light, you are making another brainless baby.Helen Caldicott, Union of Concerned Scientists
To feed a starving child is to exacerbate the world population problem.Lamont Cole

If there is going to be electricity, I would like it to be decentralized, small, solar-powered.Gar Smith, editor of the Earth Island Institute’s online magazine The Edge
The only hope for the world is to make sure there is not another United States: We can’t let other countries have the same number of cars, the amount of industrialization, we have in the U.S. We have to stop these Third World countries right where they are. And it is important to the rest of the world to make sure that they don’t suffer economically by virtue of our stopping them.
Michael Oppenheimer, Environmental Defense Fund

The continued rapid cooling of the earth since WWII is in accord with the increase in global air pollution associated with industrialization, mechanization, urbanization and exploding population.Reid Bryson, “Global Ecology; Readings towards a rational strategy for Man”, (1971)

The battle to feed humanity is over. In the 1970s, the world will undergo famines. Hundreds of millions of people are going to starve to death in spite of any crash programs embarked upon now. Population control is the only answer.
Paul Ehrlich, in The Population Bomb (1968)

I would take even money that England will not exist in the year 2000.Paul Ehrlich in (1969)

In ten years all important animal life in the sea will be extinct. Large areas of coastline will have to be evacuated because of the stench of dead fish.Paul Ehrlich, Earth Day (1970)

Before 1985, mankind will enter a genuine age of scarcity…in which the accessible supplies of many key minerals will be facing depletion.—Paul Ehrlich in (1976)

This [cooling] trend will reduce agricultural productivity for the rest of the century.Peter Gwynne, Newsweek 1976

There are ominous signs that the earth’s weather patterns have begun to change dramatically and that these changes may portend a drastic decline in food production—with serious political implications for just about every nation on earth. The drop in food production could begin quite soon… The evidence in support of these predictions has now begun to accumulate so massively that meteorologist are hard-pressed to keep up with it.
Newsweek, April 28, (1975)

This cooling has already killed hundreds of thousands of people. If it continues and no strong action is taken, it will cause world famine, world chaos and world war, and this could all come about before the year 2000.Lowell Ponte in “The Cooling”, 1976

If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder by the year 2000. … This is about twice what it would take to put us in an ice age.Kenneth E.F. Watt on air pollution and global cooling, Earth Day (1970)
