Global Warming

I do not mean to come off sounding like a jerk, but I am sure I will. If you still do not believe that global warming is caused by humans, despite all of the indisputable scientific evidence and documents, you never will. Storms on the outer surface of the sun emitting some ultraviolet rays is not the problem.

 

I still dont believe

 

meh...every thing is cyclical...we are just speeding up the process...wasnt' there something like global warming stuff when the dinos were about? i guess it was their huge piles of dino dung polluting the air...

seriously tho...we do affect global warming...however we are not the cause...persay...of it

 

Global warming is Chuck Norris turning the sun up. He thought it was too cold.

 

I would not call the scientific evidence as indisputable. As far as science goes it has been tracking the temp on earth of about 100 or so years.

Would it surprise you to learn that science thinks the earths average temp was 2 degrees higher in the last ice age.

That during the 70's there was scientific evidence that the Earth was cooling.

I found it odd that you dismiss the one thing that makes this planet warm at all. Those storms are several times the size of Earth.

I'm not saying you are wrong but I am saying you are quick to support something that we as humans know very little about.

We are not all knowing.

 

The reason why I may seem so quick to believe it is that I have had to sit through lectures and lectures and lectures and lectures on global warming and various theories as to what may be causing it. The idea that humans are the cause is the most plausible as all the data supporting it makes sense.
EDIT: and rarely in the scientific community do a large percentage of scientists ever agree with eachother

Also, the trend of a steep global temperature rise has existed for much longer than 4 years.


I also realize we are not all knowing, I am an engineer/physicist after all .

Test,

Yes while there is a cycle in global temperature, the cycle is a very very slow process, not a schizophrenic one.

EDIT: In response to Aeternus' post below me. My intentions are not to say "you are wrong, I am right!" Nothing is ever 100% in science, and the storms on the sun's surface could be a cause, or it could be one of the other established theories, or one that has not been established yet. Maybe there is a giant alien trying to slow cook us for a nice meal. What may sound insane yesterday may be very plausible the next.

I would encourage everyone to watch this. We all have nothing to worry about.

It is stories like these

That make me think if people want others to stop talking about the other side then they prolly are hiding something.

 

At one time the consensus in the scientific community was that the Sun revolved around the Earth...

 

I think it's certainly disputable that global climate change is solely caused by humans, though it would be foolish to think that humans have no impact on the planet whatsoever. Simple physics dictates that fluctuations in the sun's energy output will have some kind of impact here on earth, so the hypothesis that climate change is related at least in part to solar cycles is a reasonable one.

Greenhouse gases from human emissions could have an effect, though some simple mathematics shows that humans breathe as much CO₂ into the atmosphere as we release through industrial processes (I'm much more inclined to be worried about heavy metals and particulate matter in industrial emissions than CO₂).

Of course, this is not to say that because the hypothesis that global climate change is caused by humans is disputable, polluting the planet is perfectly fine (that's an attitude that I frankly have little patience for). There are plenty of excellent reasons to pollute the planet less -- burning hydrocarbons releases toxic elements in addition to greenhouse gases, it's the only planet we currently have that can support human life, etc.

Additionally, hydrocarbons as a primary energy source is a losing proposition. There isn't an infinite supply (simple mathematics dictates this: the planet isn't of infinite size to begin with, and very little of it consists of usable hydrocarbons), though we won't likely run out in our lifetimes. The largest supply is located in a region of the world not known for its stability. And, ultimately, there are just plain better ways of obtaining energy. Because of this, I think that if the market is left alone, we'll get to the point where most of our energy comes from renewable sources within a few decades, with a minimum of problems. But I digress...

 

I have to agree with Symen on many points. Here is my 2 cents.

I had the oppurtunity to meet and talk with many scientiest will I was stationed down in Antarctica in the mid 90's. We talked Ozone hole and global warming then. And the evidence with the data then, and still now, is that either side of the debate could be correct. However, current data shows humans are contributing to global warning... Caution here with the data. Why? Because if you are at all familiar with how grants for research are given out, I'd not say that they are always neutral. And if you look closely, you will see major groups that are "Green" funding much of the research, hense, is it no surprise that the data "may be" biased.

Are we causing changes to the Earth, probaby. To the extreme levels some would want us to beleive, not likely.

I didn't read the part about the sun, however, I do know that during the last solar cycle, it was the strongest ever recorded in sunspots and storms. And those numbers go back a couple 100 years. Now, are we going to say that man caused that? I hope not. But, there my be some tie to that and our warming.

I think we should not be in a shell, but at the same time, I dont think the sky is falling either. Is it all the Western World causing all the problems. No, but the UN would like you to think so. Deforesting of the Amazon and the poor farming practices in Africa are causing changes that may be more dramatic to the Earth then my SUV. However, the world seem to want to penalize the West, while China, India and many of the other emerging countries have major air and water pollution issues, but the UN and world seem to take a blind eye to them.

The best any of us can do is our own part. Plan our car trips wisely, try to be energy efficient, use Solar and wind if possible.

ya know...im beginning to like dat bird...flightless or not...

well said bird man...

 

hahaha!!

I have that very dinosaur pop up book right here in my house. <3

 

You wait...
