Is America ready?

Re: Is America ready?

We can get past Carbon dioxide levels by taking samples of ice, which provide a snapshot of a time period's atmospheric makeup. The Earth does go through cycles of climate change (due to oscillations in the angle of the axis around which the Earth rotates), but the change we're going through now has deviated drastically from these patterns. Most scientists agree that global warming is caused by anthropogenic gases (such as carbon dioxide).

Re: Is America ready?

When you say 'projections' your not getting the deffinition of that world right (You might know what it means but I'll continue my point...).

Good thing you are here to teach Reach proper English... >_>

I think its interesting how this went from talking about the new president to a heated global warming debate, but ill take a swing.
It has been proven that there has been a reduction in Ozone holes and whatnot as well as smaller polar cap glaciers. However, this proves only two things; 1. That it is possible to heal some of the things we have done to the planet, and 2. That damage to the planet is still happening and the momentum of it may be hard to completely stop, if possible at all.
The way i see it is that only by a massive combined effort can we help at least to slow down the process of destruction to the point where it isn't a problem anymore.

^I think we should pay attention to this to most in the subject of glacier damage.

Edit: There's a huge increase in South America as well. This might be due to the annihilation of the Amazon.

The graphs and charts may say were doomed for the future but they are missing a few keypoints. They are missing the fact that the warming period we are currently in should be nearing an end within the next few dacades, therefore ending global warming. Another fact being that the charts/graphs are only based on the current rate of CO2 production. Not taking into consideration that the rate could decrease or any other events that could chnage CO2 levels. Think about this question for a while, "How come, since humans have been releasing more CO2 through the years, the average yearly temperature increase is still very small (the temperature has only increased by about 0.75 degrees C since the late 1970s)." Also, to prove some points here, the theory of climate change was global cooling from the early 1940s to the early 1970s if you didn't know that. There was plenty of CO2 relase during those years, yet somehow the Earth was still cooling. Another instresting fact is that even with these increses in Co2 levels, the clmiate does not seem to be warming any faster than it's been for the past couple decades. No one said the temperature increase during global warming cannot change. It's not up to scientists to tell people what they think is causing global warming, especially since they aren't looking at the whole picture of possible causes for global warming. It's mostly natural, man has little effect as of now on global warming.

As for the ice caps, it would take a temperature decrease of about 3.5 degrees C in a short time period to cause major damage to the polar regoins. If there was not going to be a cooling before the year 2100 and that CO2 is the primary cause for global warming then yes, all those charts and graphs would be true. Since recent warming and cooling periods in the past have not lasted over a century, and mass produced gases are not the main factor in global warming, it's safe to say that those predictions are based on what scientists want, not the reality of things. There is still a chance that gobal warming oculd become a serious issue, however, at the rate of temperature increase now and the cycle we've seen in recent past years do not add up to anything disastrous at the moment.

For those of you who think I'm making this up, I did some research on the subject and I know what I'm talking about. Also, excuse any grammatical mistakes you see, I'm no english major so I make plenty mistakes.

Just beause a person is a scientist does not mean they know everything. From what I've seen and read, the Earth is not going through any unordinary changes. The temperature can increase how ever it want to on its own. It does not need CO2 to increase at all. These prediction scientists make are based only on if CO2 production continues at faster rates. They do not include any other possible factors that could change their theory.

Where are you getting this idea?

Yes, but it does mean they actually do experiments, and real research to back up their claims before spewing out opinions into the public domain.

You've been reading some strange material then. You claim to have done research on this material, but I'd like to know where exactly you've been getting this material since it makes bogus claims. Anyone can do 'research', i.e. read some material, but that has nothing to do with the quality or accuracy of the material (admittingly, I have feel into this trap before). What you're saying is ludicrous almost straight across the board, and I'm not going to even bother debunking it because it is self-debunking.

Re: Is America ready?

I get the idea from scientists who agree that global warming is natually occuring. If you read evidence gathered by these scientists, you should get that warming and cooling periods don't normally last more than a century. Proof supporting that is in the past hundreds of years.

I'm not directly stating my opinion. I'm including my opinion in with facts from scientists. Oh yea, these facts were found out through experiments. Experiments that show global warming is a natural cycle and that CO2 and greenhouse gases do not play much of a role in temperature change right now.

You have no clue what I've been reading and you cannot say what facts I research are false just because you disagree with them. The material I read is not bogus. I've have already stated evidence for why global warming is only natural. I have not seen you give me any evidence to prove me wrong. You should be doing some research before you come and make claims that aren't backed up by facts. There has been no major temperature changes in the past hundreds of years, years that humans have been around to produce polution. If humans are the ones causing global warming, then the temperature would show signs of it. The rate the temperature is increasing is still constant. I sure don't see any major increase do you?

...no there's not. The hole in the ozone layer has stagnated if not begun to shrink, and if there were significant damage to the ice caps, everyone'd know.

I'm surprised to find someone in this thread who actually agrees with me. It is true that the hole in the o-zone layer has stopped growing. The reason? Recent discovers done in Antarctica have shown that scientists are actually trying to hide information proving that holes in the o-zoen layer are naturally occuring and that CO2 and other gases are not the leading cause in its size change.

no...
the hole in the ozone layer was never caused by CO2 emissions, it was caused by CFCs, and a reduction in the use of CFCs is whats causing the ozone hole to shrink

I think the hole was caused by greenhouse gases in general, but please do explain what CFC's are.

They've had evidence of the cycle dating back for hundreds of thousands of years.

According to this chart, we're at the peak of a naturally-occurring cycle involving concentration of CO2 gas. Add our effects on the amount of CO2 in the air, and we've got the highest amount of CO2 for at least the past half of a million years. Notice how the low points of the graph correspond with Ice Ages, however minor they were. What does that mean the high points stand for?

I'm not directly stating my opinion. I'm including my opinion in with facts from scientists. Oh yea, these facts were found out through experiments. Experiments that show global warming is a natural cycle and that CO2 and greenhouse gases do not play much of a role in temperature change right now.

If it weren't for the CO2 cycle, the ice age cycle wouldn't even be happening. True, there have been experiments, but they were based on the CO2 content of ice cores.

Compared to the last half a million years, it's an extremely major increase. Look at the chart I posted. The rate right now is practically a straight line.

But CO2 does have a supporting role.

CFC's (or chloroflourocarbons) were commonly used in refrigerators and air spray cans before the 1980's. The chlorine in them has a disastrous effect on the ozone layer, and can break up to a hundred thousand ozone molecules before it is removed from the stratosphere. Fortunately, they were removed from popular use, but according to Wikipedia, they can last in the ozone layer for up to a century. Estimated recovery time is 2065-2070, but by then we might all be screwed.
