\/ \/ \/ I hope you know this isn't the first time our world has undergone global warming. Hmm, I visted Colorado National Park a few months ago and they were talking about how one huge area was once covered by a mile thick glacier. But, there was nothing there now. How do you think it melted? Hmm...GLOBAL WARMING! Our world is coming out of an ice age, global warming isn't new.
sea levels rising due to global warming is a load of bollocks. - ice takes up a greater surface area than water does (air trapped etc.) - the space where the ice is/was will be filled with water (basic displacement)
And suprisingly enough (for you anyway) the trend in global warming over the last hundred million years has correlated directly with the atmospheric concentration of greenhouse gases. Past dramatic increases in global temperatures are the direct results of a massive releases of carbon dioxide and methane, most notably through meteor impact leading to vapourisation of carbonate rocks, imbalances in natural volcanic activity and destabilisation of oceanic methane hydrates. Over the past thousand years, global temperatures and carbon dioxide levels have risen incontrivertably as a result of human industrial activity. Atmospheric concentration of carbon dioxide has risen by 100 parts per million in the last 150 years [source]; if we compare that with any interglacial cycles, which see 100ppm increases over periods of 5-20 thousand years, the evidence for industry as the main factor contributing to the enhancement of the greenhouse effect and subsequent global warming is clear.
I don't wanna change the topic and all, but I've recently read an article about global warming, and it says that if we continue creating massive holes in our layer the Earth's temperature will increase radically(like 2-3 Celsius). With this, natural disasters (such as Katrina and the Tsunami thingy) will happen much more often, and with more power. Not to mention that the ice in Antarctica is slowly melting in chunks, increasing the sea level significantly. So theoretically we will be gone in the next century or so...or else how will we live with nature slowly "reseting" itself? (like Day after Tomorrow)
The earth won't die within the next conceivable hundred generations unless some stupid ass post apocolypic event happens from a world war 3 where multiple destructive forces are hitting eachother with everything they have. Naturally, even after that type of a war, the earth will still exist, just like every other planet in our solar system, and the only time it should die is when the sun dies (which is projected in slightly under 5 billion years, as far as science is concerned, as far as most religion is concerned, a few thousand more years), causing a potential super nova (most destructive force known to men) and wiping out everything remotely near itself, or via lack of sunlight leading to lack of nutrients for the planet, either of those 2.
The world won't end for a good chunk of time. If you watch certain programs on TV or read certain articles, they make it sound like the world will end soon, like another century. Truth is, crap like this (global warming) happens in a cycle, it's just the life of our Earth. I don't see any of us having to worry, including our children and their children after them, right now about it.
Actually our sun is too small to go supernova, not that the earth won't get fried when it becomes a red giant. Tkim2008: I agree. Although global warming has nothing to do with the hole in the ozone layer.
Dementia: Ok, the world might be here way longer, but what will it matter if we're not going to be around in the next century? There's no way we can successfully survive a dramatic climate change.
Says who? Ever heard of natural selection? Ever consider the scientific theories of how we came about from a single cell (and the theory of global warming is indeed scientific), and how a ---- roach can survive the heat given off by a nuclear bomb? Honestly, the human race will not become extinct anytime remotely soon, and the closest planets we could feasibly live on, would require very precise measures to assure they do, not to mention a capsule large enough to transport up to 6 billion passengers to a planet. Don't even bother mentioning 'utopia' or 'only take the strong', etc. as we all know that would basically not include anyone without any form of decent money.\ In the ABSOLUTE worst case scenario, there are cells that will live, divide, and remake the human race as scientists can explain it (and, once again, global warming IS a scientific object).
You realize a 'dramatic' climate change would still take like decades? It's not like we're all going to wake up and be scorched to death. Likely we'd be able to develop technology and such to survive and if we didn't, like dementia said, species would adapt to the environment and th human cell would survive, thus given the change to evolve over the next 100's of million years.
lololol no gg... the world isnt going to end because of natural causes, global warming isnt effecting us that much atm or people would be taking actual actions. well at least imo
