Global Warming... is it real?

So I love seeing people talk about global warming, but what i don't love is that sometimes they have no idea what they are talking about... did you know that if all the polar ice caps melted the oceans would actually shrink?!?!?! probably not, but its true. Ice is less dense than liquid water, so when the polar ice caps melt, the ocean height will actually decrease in theory... but while these polar ice caps are melting and temperatures are rising, the ocean water is getting warmer which causes the molecules to expand which will in turn cause the ocean levels to rise... so melting polar ice caps doesnt cause the ocean to rise, rising ocean temperature do... now if all the ice off of land masses were to melt and enter the ocean then the ocean would rise due to that ice melting... and this is only one fact people seem to misconstrue... just to let you know, the crazy hot temperatures in the US this year is due to el nino, not global warming... global warming can only be crdited to about half a degree celcius right now. What do you guys think? is global wamring really happening?

I'm certain that the planet is getting warmer. What I'm not sure about is if its caused by human activity or just a natural cycle. I live in the UK and have noticed over the last 10 years that the winters are now very mild and the summers seem toget hotter every year. I know that 10 years is not enough to show any sort of trend, but I think all those guys and girls with Phd's cant be wrong! I think we need to approach this from two angles: 1 - How can we reduce our impact on the environment 2 - How will we deal with rising temperatures and the effects of it What we should look to do is reduce our impact, there are many things you can do to help. We dont all have to go and live in caves and become veggies. I like this blog www.microgreen.blogspot.com - I like the concept of being able to make a difference without giving up a modern lifestyle.

hmm ya i agree somewhat... i mean the past 10 years there really hasnt been a seeable change, but its a good idea we each try to be more energetically aware and try to save energy.

Hi One this is CERTAIN !! Global Warming is happening!!! It is not just the fact that the weather is supposed to be getting warmer!! Here in the UK our weather is now totally and I mean TOTALLY beserk!!!!! We are world renowned for being a nation who talks about nothing but the weather, but this weather here in the UK is just getting ridiculous!!!!! I mean, I dont mind the rain, but hells teeth....... let us have a little bit of sun now and again!!! And the Cold today!!! It is so bitterly cold!!!! Nearly February, and the winter is just starting!!!!!!!1 Oh yes!!!!!!!!!! Global Warming is a FACT !

but as it says in my discussion... global warming cannot be blamed for the crazy weather around the past year... that is el nino... global warming is only responsible for a percentage of a celcius degree change.

I took a class in meteorology last fall and even though the global warming issue wasn't pressed, or hardly even mentioned at all, I noticed when I was looking at various charts and graphs that there have been, since industrialization, some very noticeable effects. Also, when you learn about the atmosphere and how the incoming radiation and outgoing radiation are in such delicate balance, it's easy to see how an increase in greenhouse gases would throw that balance off very easily. Reading some of the responses here is somewhat funny/worrisome. What people need to realize is that global warming isn't something you'll notice the effects of over the course of a few days or even a few years. Global warming doesn't mean that the whole planet is suddenly uncomfortably hot. Winter doesn't go away because of global warming. Cold weather doesn't go away. That's not what it's about.

ya that's what i have noticed too.. that people dont really understand it... i think because so few really understand it that is why so many people don't really believe it... how can you believe what you dont understand

As George Carlin said- "We haven't learned how to care for one another, we're gonna save the f--- planet?I'm getting tired of that s--t. Tired of that s--t. I'm tired of f---g Earth Day, I'm tired of these self-righteous environmentalists, these white, bourgeois liberals who think the only thing wrong with this country is there aren't enough bicycle paths. People trying to make the world save for their Volvos. Besides, environmentalists don't give a s--t about the planet. They don't care about the planet. Not in the abstract they don't. Not in the abstract they don't. You know what they're interested in? A clean place to live. Their own habitat. They're worried that some day in the future, they might be personally inconvenienced. Narrow, unenlightened self-interest doesn't impress me."Besides, there is nothing wrong with the planet. Nothing wrong with the planet. The planet is fine. The PEOPLE are --ed. Difference. Difference. The planet is fine. Compared to the people, the planet is doing great. Been here four and a half billion years. Did you ever think about the arithmetic? The planet has been here four and a half billion years. We've been here, what, a hundred thousand? Maybe two hundred thousand? And we've only been engaged in heavy industry for a little over two hundred years. Two hundred years versus four and a half billion. And we have the CONCEIT to think that somehow we're a threat? That somehow we're gonna put in jeopardy this beautiful little blue-green ball that's just a-floatin' around the sun?The planet has been through a lot worse than us. Been through all kinds of things worse than us. Been through earthquakes, volcanoes, plate tectonics, continental drift, solar flares, sun spots, magnetic storms, the magnetic reversal of the poles...hundreds of thousands of years of bombardment by comets and asteroids and meteors, worlwide floods, tidal waves, worldwide fires, erosion, cosmic rays, recurring ice ages...And we think some plastic bags, and some aluminum cans are going to make a difference? The planet...the planet...the planet isn't going anywhere. WE ARE!

It's hard to say. I mean why is it snowing in Los Angeles and Riverside, CA. Why is is warmer where it is usually cold. Why is COlorado getting hit so much with snow. WHo know if it is really global warming. It is scary though to think that our future generations could be in trouble.

as it says in my post, these unusual weather patterns we have been experiencing in the US is due to el nino not global warming... global warming is just a small factor of maybe half a degree.

Indeed, global warmin is definitely a potential and long term threat. If u have noticed the temperature ard us gettin hotter each yr..yep..tat's part of the consequences we had to bear..It's kinda say insignificant u might tink..but imagine each yr it increases juz a bit..50 yrs down the road..wad exactly will happen?

That is the point of many global warming campaigns... it doesnt affect us in the long run, but will effect use years from now.
