Is Global Warming Real?

[Sithara007]

For me, I think global warming is real because we can feel it already. Global warming is the sudden increase of our earth's temperature. Global warming is really happening in our world now in fact it is getting many negative effect. . If this continue, there is a possibility that the arctic region can melt so many low lying areas may disappear.

If all the polar ice melts, then the sea level can rise by as much as 100 meters, and this is a huge number. Because the majority of the human population is currently residing in areas which are less than 100 meters in height from the main sea level. And this includes most of the major urban agglomerations, such as Tokyo, Dhaka, Bangkok, and Los Angeles.

Yes because as we can see now  our ozone layer is  damage because of theres is so many smoke that can a effect our ozone layer  particularly in our technology that can provide so much heat. And now the effect of the global warming is earthquake typoon heavy rain.

[rhyoanime]

it is real, global warming is now very worrying 

[jherz]

Yes all country is experiences the heat came from sun. Many got sick and skin diseases.Somebody going the pool and beach for refreshment.

Nah, global warming ain't real. Climate change is. There are parts of the world that used to be very hot and temps suddenly drops. There are also very cold climate countries that become as hot as hell.

global warming is real, the more human do the industrial development is very much and build skyscraper buildings the temperature will continue to increase, because the reflection of glass from the irregular sun to make temperatures become hot, the forest is hard to find and rare and will be arid.

Yes real, when I was a little the temperature in my place was about 22 C, but now after 20 years the temperature rises to about 33c, so I think global warming is real.

100 meters? That would take tens of thousands of years. That would require all of Greenland and a good part of the Antartica to melt.

In that time, we'll likely be in another ice age, because those are invariant being due to orbital characteristics.

Or maybe that "global warming" would mitigate the worst aspects of that coming ice age.

You think?

[Spendulus]

Yes real, when I was a little the temperature in my place was about 22 C, but now after 20 years the temperature rises to about 33c, so I think global warming is real.

A change of average seasonal or average yearly temperature for a geographical area from 22C to 33C?

No.

What planet are you on?

[RebeccaFrei]

In my opinion - yes, its real)

There are dozens of articles and works about this so I think no need to write down all the arguments here 

[jaibster]

It is way too real. We have totally destroyed our ecosystems. At this time n our country we used to wear shrugs at least, and now I'm sitting in my room thinking of turning on the AC. In some parts it is getting extremely cold while in others it is getting extremely hot. We humans can somehow survive for a while but what about animals? they don't have any means to survive.

[allthingsluxury]

Global warming is of course real, the reasons being spoon fed to you, perhaps are not.

[BulbaLord]

Ofcourse its real now all of us are experiencing the global warming  the world is totally damage from human because of cutting tress.

[perazdera]

It is. We can see every day changes happening with the clime in the world.

[DannaWonder]

I think no reason to ask this. You just need to observe the change in the weather. Nowadays stronger storms are hitting countries.

[Sithara007]

100 meters? That would take tens of thousands of years. That would require all of Greenland and a good part of the Antartica to melt.

I don't think that it will take that long. If the global warming continues at the current rates, then all the Arctic ice may be gone in 100 years time. The Antarctic ice sheet may last longer, because it is situated on top of landmass and there is an additional cooling effect as a result of elevation. But that will also be gone in a few hundred years.

[chenczane]

Yes it is real. It is REAL! If it is not real, then why icebergs in the pole are melting? Why polar bears lose their home? Why do the ocean is rising every month? Why the seasons are off balance sometimes?

It is real! You don't have to feel the effects of it. You can see it yourself. Like in our country, 20 years ago, we only reach 31 degrees celcius for the temperature. Now, for Christ sake, temperature is rising upto 38 degrees celsius. So how can they say that global warming is not real?

I am not aware of any scientific findings that support this short of a timeframe.

Realistically, the Greenland ice sheets are two miles thick...

The Sun is very low on the horizon at the poles, and half the year is dark. So the energy cannot come from the sun. It can't come from the oceans, because Greenland is like a large bowl filled with ice. The energy to melt all that ice in 100 years must come from air.

High school physics allows us to calculate what amount of energy it would take to melt Greenland in 100 years, and what temperature the air would have to be for this to happen. The worst projections of increased air temperatures from "global warming," which have been falsified, involved a warming of 5-8F.  That would not have the effect on Greenland that you have asserted because of it's altitude and location.

Believe me, it's not going to happen.

On a longer timeframe, you must admit the certainty of another ice age. Some say we are already overdue for one. How can this certain danger be disregarded in favor of wild alarmist talk about entire continents melting?

[Jet Cash]

I'm surprised that people still subscribe to the myths and propaganda generated by the globalwarming industry. The facts seem to be that ocean levels have fallen fractionally recently. We are looking at a new ice age fairly soon as part of the regular solar cycles, and there is always a short period of warming that precedes this. The puny effortsof man make not difference to this. However, man is capable of destroying the flora and fauna on the planet. If you want to make a big change to atmospheric polution, then persuade the US government to stop spreading poisons in the upper atmosphere via military fake "con trails".

Guys my grandfather land is now under water after sea level rise. Thus, i am suffer person so I believe Global Warming. You can come and see my grandfather land.

Extinction of Starlight

This week, we have another special offering—near-future fiction specifically about our atmosphere, courtesy of Arizona State University's Center for Science and the Imagination. Read more about CSI below, but I was excited to share this story from its Overview project, both because it's poignant and thrilling, and because it's about the price we might pay for using technology to indefinitely cool the planet—to embark on permanent planetary geoengineering, basically. It's one of the best fictional treatments about the nitty gritty of geoengineering the future I've ever seen. Enjoy. -the Ed. Now a word from ASU's CSI:

"This story is part of Overview: Stories in the Stratosphere, a collection of science fiction stories, art, and speculative timelines exploring the near future of the stratosphere, published by ASU's Michael G. Bennett, Joey Eschrich, and Ed Finn. From Star Trek and 2001: A Space Odyssey to The Martian, great science fiction stories have shaped how we think about voyages into deep space — but what kinds of gripping confrontations and adventures might unfold in near space, above the clouds? Overview provides several compelling answers to that question, created by renowned science fiction authors, working in collaboration with designers, illustrators, and experts in fields ranging from human spaceflight and signal processing to law and tourism. The book is free to download in EPUB and MOBI formats, as well as through Apple's iBooks Store. Learn more here."
