- lordblue, on 07/12/2008, -18/+44Amazingly enough, most parts of Antarctica, the ice is getting thicker, not melting. At least according to some scientists.

- Rotzooi, on 07/12/2008, -17/+32I can't believe the dumb comments in every climate-change thread. Americans are the only people even debating this. Sigh.
Keep expecting your God to bail you out, fools. - BlueSkyfish, on 07/12/2008, -0/+13Well you could do some research, look at the facts, and come to a conclusion yourself. Or you could take the digg route and try to base scientific truths on your political affiliation.
- Paranoidmarvin, on 07/12/2008, -0/+11Because climate trends from the last 100,000 years show a definite pattern of a sudden ice age (24,000 and 10,000 years ago) followed by steady warming, then accelerated warming and then plunging into an ice age again.
ie, the earth is going to continue warming (it has been continually warming since the last ice age), though it has been warming at a faster than expected rate, hence concerns about mankind's impact, and then plunge into an ice age again at some point.
At least, that's what ice cores and coral records have shown to have happened in the past - Isidore, on 07/12/2008, -3/+13CO2 is a significant greenhouse gas, this has been known for over 100 years (see Ahrennius). Venus is 430C hotter than it would otherwise be because of CO2.
The American Geophysical Union, warned in 2001
"There is no known geologic precedent for the transfer of carbon from the Earth's crust to atmospheric carbon dioxide, in quantities comparable to the burning of fossil fuels, without simultaneous changes in other parts of the carbon cycle and climate system."
Human are now changing the climate - scientific evidence form the guys at NASA who probably know more about planetary climate change than the armchair climatologists on Digg. http://climate.jpl.nasa.gov/evidence/
"It is unequivocal that the climate is changing, and it is very likely that this is predominantly caused by the increasing human interference with the atmosphere. These changes will transform the environmental conditions on Earth unless counter-measures are taken."

If you need surgery would you trust the knowledge and competence of someone on Digg with the same political views who had done 10 minutes googling? Or would you trust a surgeon with recognized qualifications? Why not trust the above scientists - they know more than you about climate. - inactive, on 07/12/2008, -9/+17Exactly, neglect all the facts, we don't need them.
- vroom171, on 07/12/2008, -0/+8what does this even mean?
- inactive, on 07/12/2008, -1/+8Perhaps if we just ignore the problem it might go away...
- Rotzooi, on 07/12/2008, -2/+9I am an American, even though I've left the country some time ago. It's amazing to be able to see the US from a different perspective. We're really doing quite poorly these days...
- BlueSkyfish, on 07/12/2008, -4/+11Please don't think of all Americans like that. Its just a small minority.
- Stevanoski, on 07/12/2008, -1/+8"...The breakup of ice shelves doesn't raise sea levels because that ice is already on top of sea waters, but their disintegration does speed up the process of glacial ice sliding into the seas from land areas on Antarctica and Arctic areas like Greenland. And that process does raise sea levels..."
- Rotzooi, on 07/12/2008, -5/+12I should have written 'STILL debating this'. 20 years ago, the world's scientists concluded that our climate is up to no good.
- inactive, on 07/13/2008, -0/+6are you joking?
assuming that you're not, you are demonstrating that you know nothing about science.
"Let me illustrate. I estimate that this square in front of my face contains 100,000 molecules of atmosphere. Of those 100,000 only 38 are CO2; 38 out of a hundred thousand. That makes it a trace component. Let me ask a key question: how can this tiny trace upset the entire balance of the climate of Earth? It can’t. That’s all there is to it; it can’t."
have you ever heard of a mole?
http://en.wikipedia.org/wiki/Mole_%28unit%29
1 mole = 6.02214×10^23 of something (in the case, let it be molecules)
"An ideal gas has a molar volume of 22.4 litres per mole at STP (see Avogadro's Law)."
so, in 22.4 liters, there are 6.02214×10^23 molecules at 25 degrees C and 1 atmosphere.
not that there are 22.4 liters in front of your face, but there is at least one. unless you are a nanomidget.
1 L = 1 dm^3 (dm = decimeter, or 10 centimeters)
so, if there are 100,000 molecules in front of your face, you are pretty close to space. if not in it.
your argument is *****. - Screwy1138, on 07/13/2008, -0/+6This is true, because of general warming temperatures. The deep cold helps maintain the 'desert' aspect of Antarctica. Warm it up a little bit, and you increase the precipitation. With increased snow, the ice pack gets thicker, which ultimately adds more pressure, and pushes the glaciers out faster. Combine that with just a little more melt around the edges, which provide glacial lubrication, and you get faster, thicker glaciers - which is exactly what we're seeing.
This is how you get valid science saying it's warmer, and valid science saying the glaciers, in many areas, are getting thicker. Both are true, for now.
Please note that while this supports a general warming climate theory, I personally do not have enough information to have an opinion on whether this is human caused. My personal feeling is rather simple, pollution is bad, mm'kay? - masterm1nd, on 07/12/2008, -6/+12Climate is change. Let me know when the climate doesn't change, that's when I'll be worried.
- Stevanoski, on 07/12/2008, -4/+9Dang man made climate change causing mars to lose ice cap and Neptune to grow a new spot.
- xL0Sx, on 07/12/2008, -8/+13So can someone please explain to me if I should be scared of burning to death with Global Warming, or freezing. Someone tell me what to think!?
http://digg.com/general_sciences/The_Sun_is_Dead_C ... - Nodaki, on 07/11/2008, -3/+8Buying real estate 20 miles inland from the coast may be beach front property in another 50 years. Oh noes what would we do without Florida.
- superkendall, on 07/12/2008, -8/+13Ahh, the Alarmist brigade is back and digging down anyone with scientific thought that disagrees with the sacred word!
- Ninh, on 07/12/2008, -3/+8Amazingly avalanches do the same, even in winter, although less so in summer.
- lennybird, on 07/13/2008, -0/+450 years from now, the Earth will be a smoldering core representing the Bush Administration's past achievements.
- matttay, on 07/12/2008, -1/+5Here's latest data on the antarctic (southern hemisphere) ice:
http://nsidc.org/data/seaice_index/s_plot.html
As you can see from the graph, it's at a 20 year high, and increasing. - antoniuk, on 07/12/2008, -3/+7I blame cell phone radiation and gas emissions from fat people eating McDonald's while on their cellphones emitting more radiation.
- waspbr, on 07/12/2008, -4/+8well, global warming is very real, although like most atmospheric phenomena it is non-linear and full of uncertainties and variables, that is why most of the theory is based on statistical evidence rather then a clear cut relationship or law. The more precise term would be climate change, and that is undeniable. The Sun's influence may be diminishing like the news u posted proposed, but that may very well be a lucky break, ie, things could be worse if the solar cycle was on a different point.
So yeah, climate change is very real - thedinomeister, on 07/12/2008, -2/+5First of all, this is not about energy. I am all for alternative energy sources, recycling, keeping our environment clean and poison free-- but the claims of global warming are absurd and ridiculous on every level. 500 climatologists in the IPCC have already resigned because they realize that the more information they gather, the less likely AGW is a possibility.
Clearly you don't know what you are talking about anyways -- I think you meant "Venus" not "Mars".
- superkendall, on 07/12/2008, -0/+3No need to change anything then if that's all the time we have.
- Isidore, on 07/12/2008, -2/+5This one reason why NASA believes in human caused climate change
http://climate.jpl.nasa.gov/keyIndicators/
see ice mass loss - eclectro, on 07/12/2008, -1/+4Actually the physical strain exceeds that of the freezing temperatures to hold it together, not unlike ice cracking on a road during winter. I'm not saying that global warming is not a factor, just that the mechanics may be different than assumed. What will additionally speed things up is the additional surface area of the ice exposed to unfrozen water. I bet this could be computer modeled.
- Paranoidmarvin, on 07/12/2008, -1/+4We barely know anything about our own climate, let alone Mars, so observations from Mars have to be taken with a very large pinch of salt.
For all we know, Mars could be on a 40 yr cycle of cooling and heating - but we've only been closely observing the planet for the last 20. - kbro, on 07/13/2008, -0/+2Hey, that is not fair. You posted a link to a chart that is simple and interesting!
It will be quickly ignored by all who don't like what it says. - nixfu, on 07/13/2008, -0/+2The Arctic, getting warmer:
“The Arctic ocean is warming up, icebergs are growing scarcer and in some places the seals are finding the water too hot,” according to a report to the Commerce Department yesterday from US Consulate, at Bergen, Norway. Reports from fishermen, seal hunters and explorers, he declared, all point to a radical change in climate conditions and hitherto unheard-of temperatures in the Arctic zone.
“Exploration expeditions report that scarcely any ice has been met with as far north as 81 degrees 29 minutes. Soundings to a depth of 3,100 meters showed the gulf stream still very warm.
Great masses of ice have been replaced by moraines of earth and stones, the report continued, while at many points well-known glaciers have entirely disappeared.
Very few seals and no white fish are found in the eastern Arctic, while vast shoals of herring and smelts, which have never before ventured so far north, are being encountered in the old seal fishing grounds.”
Printed in this morning's New York Times?
No, the U.S. Weather Bureau, ****1922****.

- JigoroKano, on 07/12/2008, -3/+5You're relying on science to save you when you don't even believe in science?
You have your beliefs which are religious and or political and then you accept science which confirms your beliefs and reject it when it doesn't... like every other idiot since the dawn of mankind. - inactive, on 07/13/2008, -0/+2actually, EffZee, it does matter. the mole is a simple chemistry concept. it is the first thing you learn in general chemistry. literally. any and every scientist knows about it. the fact that thedinomeister didn't know about a simple chemistry concept tells me that he shouldn't be arguing about a complex science like climate change.
- spriggig, on 07/12/2008, -1/+3This site and the two linked images are SUPPORTING the global warming hypothosis. So, yeah, it does help.
- ultraJesus, on 07/13/2008, -1/+3Everyone here is a ***** armchair expert.
- calon9, on 07/13/2008, -1/+3I'm a Canadian living in the US for the past couple of decades. I always feared that the US entertain-u-news (and politicization of it) would have had a negative impact on me. Luckily I'm still a thinking, rational person.
But I have earned an immense appreciation for news (PBS, Canadian, some European) that I used to think of as mundane and boring while growing up. There's nothing like seeing a caricature of news as exists in the US to appreciate what real news should be; And appreciate how important it is for the soul of a country. - Stevanoski, on 07/12/2008, -5/+7The two biggest ice shelves in Antarctica – the Ross and the Ronne – lie on the edges of the Antarctic mainland show no signs of melting.
- paker, on 07/12/2008, -1/+3If the world is getting warmer than there would be more evaporation causing more precipitation in the form of rain and snow.
- inactive, on 07/13/2008, -0/+2LOL your research on the issue is extensive.
- nixfu, on 07/13/2008, -0/+1Ignorance is how the media is fooling people into thinking that humans cause catastrophic climate change,
Ignorance is how Al Gore got away with LIES. - Terr01, on 07/13/2008, -0/+1Just testing out a metaphor...
You have some nice refreshing water in a glass cup. The cup is in the sunlight, and there's a piece of plastic wrap above it, covering half of it. Water forms, beads on the plastic, and falls down back into the cup.
For the ice shelf, saying "the ice is thicker in the middle, it can't be losing ice" is like saying "But extra water drips INTO the cup."
In reality, the water going in is highly-visible but ultimately small recovered fraction of the losses. The cup will eventually be dry. - bruce86, on 07/12/2008, -3/+4Lol Masterm1nd. The irony of you pointing out my irony is that you are the who is wrong. Maybe you should take my own advice that you gave me. The only difference between climate and weather is the period of time, correct. And trust me, climate shouldn't change so fast. Usually when it does, something is going down, that isn't natural.
- bruce86, on 07/13/2008, -0/+1Ozone only makes up 0.00006% of the atmosphere, but yet it protects life by blocking a chunk of harmful UV rays. It takes only 1ppm to start degrading rubber. Takes 100ppm in the air we breath to start irritating our eyes and lungs. 400 ppm to be classified to be very unhealthy. But what eva its too small to do anything AMRIGHT!?!
- Comanche, on 07/13/2008, -0/+1Well the temeratures havent changed in Winnipeg (The center of North America), where I live. 95F summers and -49F winters. So global warming fear mongers can go ***** themselves.
- inactive, on 07/13/2008, -0/+1was this really a joke?! i think thedinomeister is being serious.
- Stevanoski, on 07/13/2008, -0/+1@colon9 will be glad when you go home to your sanitized government controlled CBC. Pssst, don't have any opinions on your own, you might go to jail.
