oh good. another religous debate!  

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......

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

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.

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.

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.

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.

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

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

Mars needs cows

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...

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.

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.
