As for the sunspot cycle it is likely to have only a minimal effect on global warming due to the magnitude of it, its cyclic nature and the thermal inertia of the oceans.


Bestonnet_00:

It already has happened with *The Little Ice Age*, a/k/a the *The Maunder Minimum*. It was not slight then -- it is not only possible, but it has already occurred. The sun is a pulsating star. It is a very mild pulsating star, but a pulsating star, nevertheless. Ice ages and warming periods have happened previously, before the advent of recorded history. The trends show up in the geological records.

Eventually, the Sun will become a red giant, and everything on Earth will be fried, scorched (unless Earth is thrown out of the Solar System first, in which case, we are really gone). Regardless, the Sun will eventually become a white dwarf and will fade in luminosity until it becomes a black dwarf, disappearing completely from sight (as if there will be anybody left to see it then). There is no escape. Stellar evolution happens.

Anyway, in addition, simply to give you something else to sleep on, the great Andromeda Galaxy in our very own Local Group of Galaxies is approaching us (The Milky Way, a/k/a The Galaxy), or we are approaching it--or both are approaching each other. The two galaxies should meet in about 3 to 5 billion years. Even though few of the stars will touch, the gravitational forces will be tremendous and, again, we might have a big problem. We simply cannot win!

Now, go to beddy bye and sleep tight. For insomnia, it helps to count sheep first...

Cheers!

By the time the sun becomes a red giant or Andromodea hits us we would be advanced enough to survive it.

Assuming of course that we still exist then.

Dreamer...

The collision of Andromeda and the Milky Way will not affect individual stars that much, because there is so much space between stars. However, the tidal forces will be tremendous and might be of great consequence. By that time, the Sun might have already become a red giant, and we would have been fried!

Of course, there is the end result of the universe (eons from now) where the only things which are expected to be left are electron-positron pairs (circling at enormous distances) which, themselves, will eventually anihilate ending in energy. I do not think that we can survive that since there will be no *we* left to tell the tale.

On the other hand, I do not think that humans are apt to be able to survive themselves. Enough humans have spent their entire lives attempting to annihilate each other (wars, etc.), and I have few hopes for Homo Sapiens Sapiens' continued existence. We will probably take the entire animal kingdom with us. All that might be left (temporarily) would be cockroaches, et al., and when Sun becomes a white dwarf star (eventually fading to become a black dwarf star) no species will exist.

Here is, from my e-mail today, a URL from *Spaceflight Now* which shows Mars at its closest. However, there is, in addition, a series of photographs of galactic collisions in the early Universe, followed by a simulation of Andromeda colliding with the Milky Way, in particular. I guess the folks at *Spaceflight Now* knew I needed it. (I must thank them for delivering the simulation pictures on time.)

The URL is:

http://spaceflightnow.com/news/n0107/05hstmars/

I am skeptical about humankind's ability to survive, given its previous destructive behavior. I expect humans might end up as stone-age-like troglodytes.

As a species, we do not know better, so we will not do better. #&%@#!!

One could argue that our inborn desire to annihilate each other is what brought us this far, and is likely to bring us much farther.
It is not a pretty picture I admit, but that unfortunately does not make it any less possible.

You also have a rather pessimistic view of the survival chances of live itself. Life on this planet has already survived several major catastrophes, larger then meteors hitting earth and killing of all those big lizards or a couple of apes suddenly gaining selfawareness. Life is suprisingly adaptble and mankind will barley make a bump into it.

One should also not easily assume that life will perish with our sun. Even if mankind does not make far enough to bring the seed of life to another solarsystem, we are speaking here of a long time. Who knows if there won't evolve lifeforms on this planet after we ahve lelft it, who will have the ability to make the jump. They don't even have to be intelligent to do so.

Look at the theory of panspermia for inspiration, how life could have come from somewhere else or could go somewhere. Life as we know it is not nessecerally bound to the life of our sun.

And even if someday the last of our distant cousins dies that does not mean the end of any kind of life. As long as there exists a medium to have pattern in it there is a chance of some sort of existence

And then there is always God...

You should have a bit more of imagination and faith in mother nature.

Careful there, ljbrs:

You're providing material for at least 100 sermons by "religionists" proclaiming the Good News. They don't want to hear YOUR vision of the future.


I'll weigh in with Lars_H on this one. Life will continue on this planet despite our best efforts to do otherwise. I just don't buy the all-or-nothing proposition to human existence. Left to our own devices, we will follow the laws of Nature. We may overrun food stuffs and resources to the point where there may be a massive human die off. But that means the survivors will be in a better position to exploit the spoils. And our species will continue. Even if we don't make it, the whole kingdom of Insecta seems to be much better poised to adapt to whatever biosphere is left than just about any other class of animals. In the future, "your mother is a cockroach" may have a ring of truth to it.

Amen and Alleluia!

NAS Bulletin

Who is the National Academy of Sciences?

Let's see...the US' own scientific advisory council is saying that there is a real effect...so what was the issue agin?

I think it needs mentioning that the same Europeans that were made fun of recently for their lack of leadership have in fact redone the Kyoto Treaty.

More than that, it's another example of how little Europe and Japan need the US to lead. Times are a changin' and probably for the better. From the analysis I read, President Bush is the big loser as well as the prestige of of the nation that elected him to lead.

The issue is - Do we want to give up our SUVs and cushy suburban lifestyles in order to conserve our finite energy resources and protect ourselves from possible climatic changes that we are unable to predict and are poorly prepared for? In the US, the answer seems to be no. Our "leaders" know that nothing will happen fast enough to affect their political careers so they do nothing. Corporate leaders know that they will not be held liable now for what their companies do that affect the future of the environment, so they do nothing but watch their quarterly reports. And citizens of the US (and probably abroad as well) keep chugging along happily polluting and wasting believing that nothing 'bad' will happen in their lifetimes (probably true). The issue is irresponsible behavior.

I've covered this already, but here it is in synopsis again: The bulletin/summary/report that the media covered is NOT the scientific report of the NAS. The scientists who conducted the study did not sign the report cited in the media; they, in fact, were not even shown the report before it was released. At least one member (I think the spelling is Lindzen) has denounced the report as being the work of political hacks who ignored the science in favor of a statement furthering their agenda, just as the IPCC scientists were not involved in writing the UN report about their study. Look at the study of the NAS itself and you will find that it does not say anything close to what the media claims it says.

Coupla points:

1. I'm not against a redone Kyoto treaty, but it would need to be vastly redone.

2. None of them have ratified it, despite the talk.

3. Great for the rest of the world; let them lead; my argument has never been based on prestige.

4. Even if it unfolds the way you believe it will, it does not make the U.S. the loser, and it's far too early to tell anyway.

5. The 'redoing' that they are doing, is based on objections of the U.S., to make it more palatable. How does that redistribute the mantle of leadership?

More commentary on Kyoto's 'revival' and the motivation behind it.

quote:
Commentary
Kyoto Is Still Doomed
By James K. Glassman, a fellow at the American Enterprise Institute and host of www.TechCentralStation.com.

BONN -- A last-minute deal yesterday managed to avert another disaster for backers of the Kyoto Protocol. Last November, talks in The Hague collapsed over how to implement the treaty. Then, in March, President Bush, following the lead of the U.S. Senate, rejected Kyoto as "fatally flawed."

What saved the protocol yesterday in Bonn were concessions to Japan and other countries that had complained of the high cost of simply cutting greenhouse-gas emissions. These nations wanted to use forests and farmlands -- "sinks" that suck carbon dioxide out of the air -- as well as emissions trading to meet their treaty obligations. Of course, these were precisely the changes that Frank Loy, the Clinton administration's top negotiator, had asked for at The Hague. He got a pie in his face, both figuratively and literally, for his efforts. In Bonn, faced with failure, the Europeans caved.

Doomed Treaty

But it remains to be seen whether Kyoto will ever go into effect. So far, with the exception of Romania, no European country has ratified the treaty -- and, after enduring long, teeth-gnashing days among the environmentalists at the last two climate-change conferences, I strongly suspect the agreement will never be implemented.

Why? Well, European politicians aren't stupid. They are merely cynical. A non-agreement helps them much more than an agreement, which, without U.S. participation, would put them at a big economic disadvantage to the Americans. And for what? Not to save the planet.

Despite plenty of research, when it comes to climate, we still know very little. We do know that the surface temperature of the earth has warmed by one degree Fahrenheit over the past century, but we also know that most of the rise occurred in the early 1900s, long before the big increase in carbon dioxide emissions from cars and power plants. Meanwhile, satellites have found no atmospheric warming over the past 20 years.

Worries about the future are based on primitive computer models that can't even describe current conditions accurately. And a special panel of the National Academy of Sciences used the word "uncertain" 43 times in 28 pages last month in a review of the state of the science.

Tentative findings are a pretty thin reed on which to rest an emissions-reduction policy which President Clinton's own Energy Department estimated would reduce America's gross domestic product by as much as 4.3% annually.

Most of the world's policy makers are well aware of the shaky foundation and high cost of Kyoto. They also know that global warming, if it exists at all, won't become a problem for another 50 years or so. So why do the Europeans oppose a high-tech shield against a real threat -- nuclear-tipped missiles launched by mistake or by rogue nations -- while they embrace expensive steps against theoretical global warming? Here are three answers:

Politics. Remember that key European governments are coalitions in which Social Democrats have a plurality of legislators but need the Green Party to form a majority, and the Greens usually get the environmental ministry. Under this setup, mainstream politicians, worried about their coalitions falling apart, are happy to pay the Greens lip-service.
In addition, Kyoto, as a treaty that tells people how they can live, is the last gasp of Europe's authoritarian left. Many in Europe are not only comfortable with such restrictions, they like imposing them. Except when it comes to running topless advertising on television, the true liberal tradition does not run deep, and socialism retains its popularity. Europeans have not had many chances lately to impose their moral will on others -- especially not on Americans -- but Kyoto is a big one, not to be neglected.

Economics. In 1997, signing Kyoto over the objection of the unanimous Senate, Vice President Al Gore got taken to the cleaners. The treaty was rigged in favor of the Europeans. At heart, Kyoto is as an economic roadblock -- like the rejection of the General Electric-Honeywell merger -- built to trip U.S. competition.
The Europeans resent cowboy capitalism. They resent that Americans work long hours, take their laptops to the beach, attract the best and brightest immigrants. Europe has its own comfortable lifestyle, with six-week vacations (just try to find a good restaurant around Bonn that's open in July) and a culture that largely disdains entrepreneurship. That's their choice, but there are costs. One is that Europe has lost leadership to the U.S. in virtually every business sector.

One way to fight back is to impose higher costs on the U.S. economy than on their own. That was the charm of Kyoto. Europeans can meet their greenhouse-gas emissions limits under a "bubble" -- that is, all of Europe gets credit for the large reductions in carbon dioxide that occurred in the 1990s in Britain (which switched from coal to gas for economic reasons, largely because of North Sea finds) and in Germany (which benefits from the post-reunification shutdown of inefficient, mainly coal-fired factories in the former East Germany). As a result, Europe reduced its overall emissions between 1990 and 1999 by 4%, toward a target of 8% below 1990 levels. The U.S., with a target for reductions of 7%, has increased its emissions 30%.

Romanticism. There is something frightening about the brand of environmentalism that many Europeans embrace. It is not a wide-open-spaces kind of American environmentalism but a romanticism-in-the-Bavarian-woods kind of European environmentalism.
Evil Multinationals

This impulse is driven not just by anti-Americanism but by paranoia. We Americans have our own sources of paranoia, embracing conspiracy theories about presidential-assassination plotters and Wall Street bankers. For Europeans, however, paranoia has its roots in Rousseauian musings about noble savages and human civilization as a destructive force. The fault lies, as always, with evil multinationals based in the U.S., the purveyors of Coca-Cola, Big Macs and big oil. Kyoto is meant to strike a blow against this kind of progress.

Don't get me wrong. The impulse to make the air and water cleaner is a decent one. It is an impulse that the U.S. has followed, generally with success. Europe has made good progress, too, but with Kyoto, it is rushing beyond sound science into the realm of radical mysticism. Will this mysticism drive the Europeans to go it alone, despite harm to their own economies? I doubt it seriously. Having had their bluff called by a courageous American president, the Europeans, steeped in hypocrisy, will finally sit down to talk sense.

I went to the link you provided(www.TechCentralStation.com) and I have to say I didn't have a lot of faith in anything there as soon as I noted the glowing John Stossel article on the front.

It's unfortunate that his demonization by others with an agenda has affected you in that way.

I felt it was shown that Stossel is hardly an exceptable source for objective news. This site was very thick with Stossel material. This leads me to associate the site with Stossel(take a look at all the Stossel links!)

When I look at interesting news sources, I often go to random sites to try to get different takes on what I feel are the important news stories. I do not go to a familiar site that is bound to give me the story I want.

I have no news sites bookmarked so that I don't fall into this. If anyone looks hard anough they are bound to find what they want to see. That's just my 2 cents and I'm sorry if it sounds harsh but I really didn't feel that this was a fair news source.

Agreed that John Stossel is not an objective source. Does that condemn everyone associated with him. I suppose I should disregard anything by anyone who likes Greenpeace.
