People seem to be in serious denial about the reality that is global warming. Scientists everywhere now have confirmed that this phenomenon is for real. The freakish hurricanes and tornados that are tearing across the globe are a sign. Last year was one of the hottest on the record. There's something in the wind, you can feel it yourself. Its changing.

So why are people so reluctant to a) believe b) care and c) take action? It's your own butts you're saving.

And, also you clearly don't know how physics connects to global warming, but it's useless to argue about that to an ignorant college student. Oh and btw, I really don't think smoking would help the earth. besides, i think it's ruining your ability to think straight.

How about you give me a lesson then in how physics and global warming are so directly related?

Can you walk the walk or do you just talk the talk.

Somebody needs to go to college apparently or high school or read or do something productive with their mind rather than just go 'der da der potheads are stoopid and i is smart cause i can type things.'

People who deny global warming have had their heads shoved up their butts by the bush administration and fox news.

Welcome to reality.

global warming is a reality evn if we deny it or accept it..glaciers ..ice caps are melting ..places which experienced spine chilling cold in winters has an average temperature of 28 -29 degree durin winter if its nt the sign of global warmin then what is it...we humans hav only contributed 2 all this and nw wen are nightmares r turning into reality we all are blaming each other for the mishaps...evn now we are not makin significant efforts to prevent a dead end for ourselves and only contributin to our graves rather than saving ourselves 7 mother earth...its high time all of us realise the reality n save mother earth n ourselves..

Whoah, whoah, whoah. What i was saying before that, was that the photos were taken in two different seasons. In which don't count as evidence. if they were taken in the same season they would probably have looked more similar. and it's hard to fully believe the site when it doesn't site it's sources.

And, also you clearly don't know how physics connects to global warming, but it's useless to argue about that to an ignorant college student. Oh and btw, I really don't think smoking would help the earth. besides, i think it's ruining your ability to think straight.

I don't think you have read what people are saying in this post.

Yes, glaciers recede and grow depending on the season. Yes, the world has periods of warming and freezing.

The problem is that these naturally occuring processes are accelerating very, very, very rapidly because of the greenhouse gases that we fumagate the earth with.

Physics does not tell you about environmental processes, like global warming, which you were implying. It is the study of the laws of nature (ie energy and how objects affect each other), not about what humans do to the earth. You are clearly thinking of biology.

What glaciers have you been looking at?

Numerous glaciers around the world have retreated incredibly far compared to 70 years ago.

I know this from personal experience, among other things. I used to visit Portage Glacier up in Alaska. When I was young (about 10-12 years ago), you could see the glacier from the visitor's center. There were ice floes out on the lake. It was pretty cool.

I went there a couple years ago. No glacier in sight. It had retreated so far up the valley that you had to hike out just to get a glimpse of any ice. It took less than a decade for Portage Glacier to melt that much.

There are plenty more examples. Roll your mouse over the pictures here. Yeah, that's pretty freakin' dramatic.

You know, you have to remember something. Glaciers are SEASONAL which means they recede in the summer and grow in the winter. If you notice in the alps photo's, the after photo is taken in the summer. I'm not saying the theory is wrong, just that the photo's don't make sense. And i don't know about you but i like it, anybody notice how green and beautiful it looks?

And wolfie? Physics tells you everything about the environment around you and how it works; and i really think THERMODYNAMICS kinda helps in this part. which they teach in physics

Hey there.

I'd just like to say for the people who have doubts about global warming that I can say with 100 per cent certainty that it has become a reality. actually 'reality' isn't strong enough a word, huge impending danger maybe...? Global warming has always occurred in our atmosphere hence why the earth is inhabitable. If it wasn't for global warming (in moderation of course) the planet would be about 30 degrees colder. It is because of humans that Carbon Dioxide, among other greenhouse gases, levels are increasing. They are now in total excess and are causing way too much heat to be retained. There is no doubt in my mind, and others' that global warming is an encroaching disaster waiting to happen. If anyone is interested I'm currently writing a blog explaining global warming/climate change, deforestation, desertification and eutropifcation ; their causes and effects. I haven't posted it yet as I haven't typed it out yet. But it has some useful information etc that is quite interesting and clearly shows how global warming is a reality and how it is linked to many other environmental issues.


Good day.

we've been in a "warming period" since the end of the last ice age.

but i whole-heartedly agree with your post.

The debate isn't about whether humans caused climate change. The debate is about whether we made it worse.

Indeed, the climate does go in cycles. There are periods of cooling followed by periods of warming. However, humans have thrown things a bit off balance. Prior to the Industrial Revolution, humans didn't have much of an impact on the climate. But since the 18th century, more and more pollutants have been introduced into the atmosphere by way of emissions from factories, cars, trains, etc. Greenhouse gases, such as CO2, are prevalent in these emissions.

From what I know about climate change, we're currently entering a period of warming and it's the first such period since the Industrial Revolution. Thus, there's not much to compare it to. We really have no idea how big of an impact our activities have made, but it seems reasonable to assume that we've tipped the scales somewhat.

can you tell us why the ice caps are melting more than ever before?

can you tell us why the melting speed has octupuled in the past 10 years?

do you understand that natural climate change takes place over thousands of years not decades?

You people can believe what you want, but global warming might be the dumbest thing I have ever heard of.

FYI it's Inconvenient Truth not Unconventional.

guess that means you were misinformed eh?

Once you get proof for your info tell me about it. Until then I don't believe it.

Well yeah of course global warming is real!! Just watch An Inconvenient Truth. It is pretty obvious.

"Its too easy to turn a blind eye to the light,
Its too easy to bow your head and pray,
There are some times when you should try to find your voice,
This is one voice that you must find today.

Are you hoping for a miracle
As the ice caps melt away?
No use hoping for a miracle
There's a price we'll have to pay."

Sorry Wolfie i didnt see your reply. I was talking about the hole in the ozone layar.

For all those that think global warming isnt real, stick your head out the window.

Exsatively Posilutely!!!

and this probably/definitely belongs in another thread, but I was wondering if the world leaders don't hinder the development of nuclear technology in developing countries. I thought I read something a while back about the UN making India stop developing nuclear technology and energy ... any thoughts?

lmao, why are people sfr???

from 1994 to 2000 the glaciers melting speed doubled from 2000 to 2006 it was 8x faster. courtesy of MF discovery channel.

Why don't people ever trust science. I'm really sick of dumb people saying "there's no global warming" when in reality they are just talking out their asses. Are you a scientist? Do you have any data to give me?? no. so stfu. Seriously take an envirsci class because you clearly need it.

thankyou hoops. that's what i've been saying too. WE didn't start global warming, it's natural, but WE DO AMPLIFY it with all of our pollution. It's not even America that's that bad with it, the problem is that third world countries (or China) are building butt-loads of coal power plants because they are devoloping economically but they still can't afford nuclear power plants.

i've never seen gore's movie, but i like him, he was going to legalize marijuana but ppl prefer bush over weed i guess.

Do you mean 'An Inconvenient Truth'?

I watched part of it for my AP Environmental Science class, but I didn't pay attention- I don't like Al Gore. *shrug*

Anyways, something different is happening. Yeah, there have been climate changes in the past, but never so quickly or so dramatically. I think that something WE are doing is accelerating the natural process. (pollution, greenhouse gas, fossil fuels, ...)

first off global warming is NOT a reality there might be somescientist that belive it but there are fewer that doubt global warming, everyone is being scared saying that the ice and glaciers are melting, when in fact they're not!! they're thicker and temperature's are no different than they were in the 1930's even in the 1930's they were higher than they are today so there is absolutely no reason to blow this out of proportion. also for those of you that have seen the movie "The Unconventional Truth" the hockey stick chart Al Gore shows you is blown out of proportion and has been totally discredited when asked where he got the information from or what science lab he used he could not come up with either.
