We all need reminding....

That assumes mankind is causing global warming. But if we are causing it, why is Mars warming at the same rate? Could it be it be the one thing that's never included in the computer models? ........... SOLAR activity!

oh good. another religous debate!  

Who mentioned religion..?

I always wonder how these measurements came about, or how reliable they are. After all, how many times have we actually been to Mars?

Fact is that even on Earth, measurements by satellites that measured the temperature in different layers of the Earths atmosphere were found to be faulty and had to be corrected recently. A recent documentary on British TV conveniently used the old dataset to rebuke the human influence on climate. They also used a faulty set of graphs showing the correlation of solar activity with global warming. I could go on listing the errors and faults of this "documentary" starting with the so called "scientists" (most of which are not climate scientists, but several are on the payroll of Exxon. How convenient).

The topic of global warming is of course heavily discussed within the scientific community, and there is so much we still don't understand about the complex system that is earth. However, the general tune is:

Yes, global warming is connected to solar activity to a certain degree. However, during the last decades, global warming has increased the levels expected due to solar influence (as solar influence is included in the models). It would have done so much earlier (during the 60-80s) if mankind wouldn't have at the same time produced huge amounts of sulphate aerosols which by themselves were not only responsible for "acid rain" but also change the reflectivity of the clouds, in fact making them more reflective so that during this time more heat was reflected back into space, effectively counteracting global warming. Since the mid 80ies the release of these aerosols into the atmosphere is heavily regulated and the rate of global warming has increased.

And that is the main problem: It is not about the fact that global warming happens, it is about the rate at which it happens. Even though mankind does not cause global warming by itself, we accelerate it! And it is due to this acceleration that many of the planets ecosystems (including the worlds coral reefs) have no time to adapt to the rapidly changing environment.

How easy it would be for us to just to blame the sun, and not think about our own impact on the environment......

debates about the environment have the same characteristics as a religious debate. Personally I agree with Koasati but after listening to the high priest of the greenhouse effect, David Suzuki, I'm convinced the greenies aren't interested in facts or scientific debate. That's why I equate the whole topic with religious debate. Just my opinion of course.

Global warming, yeah, right. Even though it's fiction, you should read State Of Fear by Michael Creighton. Great book. Good thinking.

Aren't cows supposed to be a major factor in "global warming"? How many cows are there in the world? Just so we can eat hamburgers and filet, and sit in our cars on leather? They're really big, each of them, with four(4) stomachs, and produce a horrendous amount of methane. What if they all farted at once? It might be the end of the world as we know it! Let's just stop having cows. Don't have a cow, man!

Here is a transcript of an excellent debate on whether or not 'Global Warming' is a crisis. WWW Link The issue isn't whether or not it's real, it's whether or not it's a CRISIS, like the environmentalists and the media would have you believe. Let's not turn into Chicken Little when it comes to 'Global Warming'. Do some research, read what you can, don't just believe something that is thrust in your face like all this 'Global Warming' propoganda. This subject falls in the number two slot on my top 5 list of stupid things about the human race that astound me.

Oh no, a global warming debate.

Speaking as an American, I don't really care about global warming. Yeah, yeah, I know what you're all thinking, but hear me out. The United States' economy is entirely dependent on oil and the politics of the Middle East. The most important thing we can do right now is diversify our energy, and use a domestic or renewable energy source. As it turns out, the best candidates for this are clean and environmentally friendly, such as wind, solar, nuclear and clean coal. America has enough coal to last 60 years or more, and joined with the other sources I listed, as well as conservation and increased energy efficiency, we can stop supporting awful regimes like the Saudis, and have a more human-rights oriented approach to the Middle East.

So by switching our primary energy sources from oil and dirty coal, we can reduce pollution, possibly reduce the effects of global warming, and allow us to quit interfering in the Middle East. So while the jury is out on global warming (to some people anyway), we can motivate ourselves to solve that problem, while solving a bunch of others. I'd say more Americans are concerned with politics and conflicts originating in the Middle East than global warming, so energy diversification is a great way to bring all people together.

And the other side of the coin are the 'scientists' that support Gore's hype. The vast majority are not climatologists, but their funding depends on them supporting the "crisis". If there is no crisis, the funding dries up. (Thirty years ago, they were warning of the coming mini ice age)
And this so called 'consensus' among those "experts", is just more hype. As Roy Spencer, Senior Scientist for Climate Studies at NASA's Marshall Space Flight Center (1984 -2001) puts it, "science isn't subject to a vote.
Even the founder of Green Peace has moved to the side of reason.

Consider this...... 1000 years ago, the Vikings didn't name the island GREENLAND because it was covered with ice. Why is is covered in ice now? Because of a global cooling cycle, and now the earth is in a warming trend.

Global warming?  What global warming?  It's April 8th and in Houston Texas last night it was 30 odd degrees F.
What's up with that?

true, thats because they are usually made by politicians who have no background in science what so ever and have no clue about what is going on at all. All that politicians (righties and greenies) care for is to further their own gain. In order to do that they (again, BOTH sides) use populistic phrases and half-truths.



Methane is one of the gases involved in Greenhouse effects and cows produce a whole lot of it. However, cows are not (and were never) considered "a major factor" in global warming even though stocks have increased dramatically in recent decades. Their methane contribution is however an additional (if small) factor to the buildup of greenhouse gases in the earths atmosphere.



Exactly, not just the US, all industrialized countries are. What harm can there be in swapping to renewable energy sources?? Solves several problems at once, but it needs a change in thinking and our will to do that.



I haven't seen the Gore movie, but I can imagine what it must be like. See the above point on politician talking about things they have no clue about.....



Yes, as I said: Global warming is much debated amongst scientists world-wide, but the vast majority is concerned about the rate at which this warming occurs.



What is now known as "the medieval warmth period" may not have been a global effect. Even then it was only the south tip of Greenland that was considered to be covered by lush grass (no one knows that exactly, another story is that Erik the Red named the un-inhabited Island he found Greenland in order to attract settlers). The problem we face today is that we put huge amounts of gases into the atmosphere which retain the heat, thus accelerating natural causes of heating. Whether this will cause major problems in the future, or whether this problem will solve itself... no one can say.

It is a mute point anyway as we should take the possibility that it could cause problems in the future to at least think about our influence on our environment and on what legacy we will leave to our children and grandchildren.

The story I had heard was that the Vikings wanted to keep Iceland to themselves because it was Green. Hence they threw the rest of the world a curveball to have them go to the ice covered place and named it Greenland. Greenland was covered with Ice even then.

And the story I heard was that Greenland had a thriving agriculture back then.






Let me give an example of what sort of 'truth' this movie is about..........
The Aral Sea, once the fourth largest in the world is only 25% of it's former size. Gore's film implies that global warming is the cause. No mention is made of the fact that the former Soviet Union diverted the rivers that once fed it.

Gore is so concerned with the raising temperature, that he wants us all to change the way we live, but he isn't willing to join us. ONE of his mansions uses 20 times the electricity of the average home in the US. He flies all over the world to attend conferences. I don't know, but it seems to me he could use the internet ....... you know, the internet he invented.



And speaking of "greenhouse gases". Humans produce not even 1% of the carbon dioxide, and other nasty stuff emitted by the volcanoes of the world.

Anyone know what the most abundant "greenhouse gas" is?
......................Water vapor.

Phoon you are correct.

It may be named accordly, but I somehow doubt it.

I'm doing my part for global warming...I'm eating all the cows...but I'm only one man! Please Help me!

Hmm, I wonder what the name for Global Warming was 100 years ago when this happened?

Everyone does realize that every once in awile the sun likes to change a bit? Its not always at a constant rate.

And the Goreacle is a fake, his mansion uses 20 times the amount of electricity than the average American home, lets not forget his private jet which puts out more crap than a 737.

The cows are all waiting to be beamed up off the planet

Mars needs cows

yeah, (this ones for vegans) if cow is so bad for us, why did 'god' make them so tasty...and slow. Support P.E.T.A., People Eating Tasty Animals.

I mowed the lawn yesterday. I had to wear an insulated jacket, and insulated gloves to keep warm while doing so.....





My wife and I pledge to do our part.



Mars needs nougat...

We need to ban dihydrogen monoxide!

Sheesh! Did anybody get the screensaver???? It's just a bit of fun to remind you to turn off your computer if you're not using it! Save a bit of power.

I was gonna get the screensaver BoXXi...but I though it would use to much energy to get to the site..so I just turned off my computer.

OK ok...I confess! I got the screensaver and used up 6 watts of power watching it...I feel so dirty!

That's really bad!! Movies like that do more harm than good as it is always a much harder task to convince people of an inconvenient truth than it is to convince them of something that confirms them in their old set ways.



Don't know where you get that number from, but volcanoes actually produce a whole lot of dust and aerosols, hence counteracting global warming. The Pinatubo-outbreak caused measurable dimming of the Asian continent and lead to a reduction in temperature.

Link to the official IPCC-Report:
WWW Link
Notice the careful phrasing, e.g. "is likely to ....". Truth is, only future generations might be able to look back an then judge whether we were right or not. But do we really want to take that chance?



No?? Who told you that? Water vapor is not considered a greenhouse gas.



That's evil messiah.



soooooo true!



I don't use screensavers BoXXi, but I think this is a really smart idea for one.

Don't beans produce Green House-Gases?
