Why do you think global warming is happening. Is it's mans fault or a natural nature cycle. We have the highest global temperature ever recorded in the last 1000 years as far as scientists can tell. If it is man's fault, How do you think we can reduce it.
I didn't make it!
I think it is a natural cycle that may be sped up by human causes. If we did not exist then climate change would still happen, except instead of happening within the next 100 years it would happen within maybe the net 500 or 1000.
But it is scientific fact that it is a cycle. We have had ice ages and warming periods. Hell, at points the carbon dioxide level was so high that almost no animal could survive outside of the ocean because of it. Then at another point the oxygen level rose so high that sometimes a thunderstorm would cause the sky to literally catch fire, and rain destruction down upon the Earth.
Earth's climate has changed so much in the past 4 billion years I don't think we can say what it is "supposed" to be.
Seeing as carbon dioxide holds heat more so than good ole O2, and the fact that we put out 14 gigatons of CO2 per year versus a natural 2 gigatons per year, yes we have something to do with it. To stop it we need a viable total alternative to oil and other fossil based materials for fuel and power purposes.
No! I'm Spamacus!

As I have always said, I could care less whether climate change is just a cycle or affected by human actions. In the end when sealevels are up twenty feet, arable land turns to desert, or whatever, name blaming isn't going to change the fact that it will be a catastrophic problem for everyone. When people are struggling to find food, for example, I don't think knowing that it's only a natural event is going to comfort them any.
It's irresponsible to remain inactive by making the excuse "We just don't know". Am I saying it is entirely our own fault? Of course not. It's a combination of both natural and human actions. I still believe we should clean up our act, if only because it's the right thing to do.
Fossil fuels are dirty. If people don't understand the threat of climate change, they should at least be concerned about health issues. Coal is not clean. Have you ever seen the by-products created from its burning? There have been plenty of studies detailing their effects on health.
At the very least we should be concerned about alternative sources of energy. It's easy to think that their is an endless supply of fuel, but within the next few decades the price is going to keep rising. Just look right now at such basic goods as milk. Half a dollar might not be devastating now, but what happens in fifty years if we don't do anything now?
It's 94 degrees in my room right now and is causing me to rant, so I should just end it here... :uhm:
I see the natural cause. But based on the graphs, This is ridiculous. Heres a rough sketch of one. / / / Now / / /\ / /\ / \ / / \ Ice age / \ / / \/\_____________/ \/Goddamn space things. Well I'm not gonna fix this but the big part is us. That is how hight temps have risen. And the part where It get's higher then anywhere else Is about time when the car was invented. Yes it is a natural cycle but what we humans have done is ridiculous. Ensign has a point. The main problem here is us in America and our consumption of gas. If the other countrys get smart and cut off our oil suply. We are screwed. We are the main problem in global warming because of our emmisions from gas powered cars. We like the big cars that consume alot of gas. We don't care about the MPG, all we care about is the size.
Whether people believe on global warming or not, they should nevertheless consider the following points:
1. There's only limited amount of oil, coal & gas in Earth and the global energy consumption increases rapidly, especially in China and India. Western dependency on Russian and Middle East oil is a serious security issue which greatly limits the needed actions against these two entities. Furthermore, dependency on fossil fuels also significantly increases the risk of global conflict from shrinking energy resources (the issue with Arctic?). The oil prices are getting higher all the time and it won't last forever. Alternative energy sources aren't just beneficial, they're a necessity.
2. By energy conservation, using energy-friendly appliances & comparing energy companies you will save hundreds of dollars/euros etc. a year from your electricity bill, money which surely can be used more effectively.
3. Can we really afford to take a risk that we don't contribute on global warming at significant way? There's just one planet Earth and technological & political development won't allow us to occupy Earth-like planet for some next 100 years, if not for longer. How about your grand-children?
we Bangladeshis are already feeling the effects of global warming,i.e increase in floods,flash floods and there has been massive climate change in our country.winter feels no longer like winter anymore. Obviously western nations alone cannot be blamed. Now some are saying they will dig the North Pole to find potential sources of fossil fuels. off-topic:can arable land be uh 'artificially' created? you know digging up the river bed and using that amount of soil to increase amount of arable lands,or crop growing islands? just an idea.
I belive that global warming is real and is a worldwide threat. We either need to come up with a way to get the CFC molecules out of the stratosphere and then depending on how much time it would take to get them out and if its a reasonable thing to do, Order all minor companies, and some major ones, to stop all actions the realese pollutants and restrict driving times. But that is only if its a reasonable amount of time to get the CFC molecules out of the stratosphere. For those who don't know, CFC chemicals were what caused the hole in the ozone in 1985. The hole is still there but its been closed a bit. We no longer use those chemicals but their molecules can remain active in the stratosphere for 60-120 years. Thats one of the main problems.

That's all very well, and is indeed, a problem, but it has nothing at all to do with global warming. That is greenhouse gasses such as CO2 causing a "greenhouse effect", in which heat is trapped in the atmosphere.
It is a serious problem, and something needs to be done. Even if the motive behind it is the oil running out, rather than the Earth warming.
Sparsely populated nations which tend to be huge usually needs to open up a bit for people living in low areas where water levels are rising.
