danarhea said:Yup, you read it right. No matter what we do, every living thing on the earth is going to die. Absolutely nothing we can do about it.
Why am I so sure? It has a lot to with the lifecycle of a star. As it burns up more of its fuel, it grows hotter. All of life on earth, from humans down to microbes, came about only in a small fraction of the life of our sun. And eventually it will all come to an end. Contrary to popular belief, the Earth is not going to live for another few billion years, but relax. We still have a few hundred million years before we all die.
The first stage will be what is called the wet greenhouse effect. During this period of time, the Earth's climate will grow much warmer. Because of this warming, more of our atmosphere is going to boil off into space. This is happening right now, but is on the order of about 1 cm per year. As the Earth warms, this rate of boiling off will increase, and the Earth will warm further, locked in an endless loop of boiling off and further heating.
In this first stage will be the end of the age of plants, as chloroplasts of plants break down, resulting in the death of all plant life. This will occur at about 700 million years from now. Soon after every living thing on the earth will die, except for some microbes, which will give the earth a pink color instead of the blue color it has now.
The second stage will be the dry greenhouse effect, in which the Earth will become hot, dry, and desolate, with no living thing remaining. This will occur about 1 billion years after the age of plants has ended. A few billion years after that, the sun will engulf the Earth, because as it has heated up, its chromosphere has expanded. This will happen before the sun even starts its red giant stage of life. When that happens, the sun will blow off a huge coronal mass that will scorch all planets in the solar system. At that time, our solar system will be dead, with no possibility of anything being able to live on any planet in the system.
My source for this was a seminar from the University of Washington which was broadcast on Dish Network. I found it so fascinating that I saved it on my DVR, then ran it off on a DVD.
So, now knowing that the Earth doesnt have as long to live as people might think, my question is why are we in such a hurry to speed the process up?
Canuck said:does that mean we should racing to speed up the process
So you think the fact global warming started at the same time as the industrial revolution, is a coincidence then ?Napoleon's Nightingale said:Global Warming is a natural process which is followed by an ice age. Look up the Milankovitch Cycles and the Milankovitch Effect...they explain everything. It's not the armagedon it's been painted to be.

"Are our 2 rovers spewing out so much pollution that they are having a negative impact on the Martian climate" :lol:Busta said:I don't understand. If global warming started with the Industrial Revolution, then what stoped the last Ice-Age? Or are you saying that the Ice Age lasted up until the Industrial Revolution?
Also, any thoughts as to the Martian global worming?

Are our 2 rovers spewing out so much pollution that they are having a negative impact on the Martian climate (such as it is)?

I would like to see data for solar radiation flux levels & solar temperature for the last century. Maybe warming is due to the sun, if as they say... Mars is warming also. Also can how another 0.5% of CO2 or however much, have a significant effect on earth temperature when the predominant greenhouse gas water vapour which is present & always has been & as a far higher proportion of the atmosphere.
If you had cared to read my meanderingsNapoleon's Nightingale said:I have just the thing to put a stop to this nonsense. These are charts of the Earth's climate over the past 40,000 years. Global Warming is a natural process. Period.

you would have noticed
that global changes do exist, that we know very little of.
we don't need charts to tell us this
But the spewing up of greenhouse gases ,hastens the violent changes.
And anyone advocating that we should disregard this corelation
are not going to convince people that pollution is a good thing
perhaps when you need gas masks to breath you will concur
by then you may stand agape and scratch your head and exclaim but the charts say so
Scarecrow Akhbar said:Hey. I've been looking all over for charts like that. Thanks.
Napoleon's Nightingale said:Oh and by the way, volcanos and fissures spew out more carbon dioxide, sulfur dioxide, fluorine, and chlorine in one belch than the entire human civilization has. Why are you so concerned about carbon dioxide anyway? We do have plants on this planet.
OnionCollection said:The reason is that the co2 spike has been caused by man made co2 emissions. co2 is being added to the atmosphere far faster it can be removed.
OnionCollection said:Volcanoes annually emit about 1% of the carbon dioxide that humans emit annually. Hence why co2 levels in the atmosphere have sky rocketed since the beginning of the industrial revolution.
OnionCollection said:Take a look at the graph you posted of co2 levels over the last 200,000 years: http://www.grida.no/climate/vital/02.htm. It does seem cyclic, but note that the graph ends at 280ppm. Well the co2 in the atmosphere was 280ppm in the 1800's, and had been at that level for quite some time. But since then it has risen to 380ppm. Plot that on the graph and you will see that's a huge spike (it goes right off the top), which is completely out of character with the normal course of co2 changes on the graph. A better graph that displays this: http://www.environment.sa.gov.au/sustainability/images/c02_levels.jpg

Napoleon's Nightingale said:Carbon dioxide is not the only greenhouse gas emitted by volcanos. You also have to take into account the fact that the Earth was much more volcanically active in the past and that volcanos are all interconnected. Either way you look at it, the amount of greenhouse gases released by humans has had only a minescule effect on global warming.
We must also take into account the number of natural phenomena which have taken place in recent years which have had an impact on the earth's magnetic field and the earth's rate of rotation. Both of them affect the global warming process. Not to mention the increase in solar output and intensity of solar flares over the past 10 years.

Partially, yes.
