It is so difficult for humans to cut back on greenhouse gases because of the ways that they already tried, they haven't worked. They tried using large pumps to draw water from beneath the ice and spray it on the surface. Because it is the coldest part, it will cause the water to freeze rapidly. If they were to add all of the money that they have to pay, they have to pay $500 billion USD. The ice helps regulate temperatures on Earth. With ice, bad things happen like temperatures getting very high.

I agree with you Kristina, they didn't use the pumps yet, and it was just an estimate of how much it would cost to do it. But, anyway great job! 3/13/2017 04:24:16 pm
I totally agree with you Kristina! If they pump water from beneath the ice and spray on the surface, it can freeze really fast. There can be other ways that can help situation. Great Job!

Good Job. I agree with you. The reason people are doubting it so much is because it is only a theory and estimations and others have not worked

I see what you're trying to say, but at least the scientists should spread the news as much as possible to the public, but also at least try their best to do someone. My suggestion would be to start small and do anything we can do right now, and later on work on it even more!

Some ways that we can reduce greenhouse gases are by shutting down factories that produce energy, and replace them with other healthier and cleaner methods of getting energy. Closing other factories that produce materials could possibly be replaced by other methods of creating that product in a cleaner way.

It's so difficult for humans to cut back on greenhouse gases because we need it. Some greenhouse gases are really important for us and the Earth, if people cut back on greenhouse gases there is going to be a situation. Since that is the only effective way to help the late summer ice, scientists are having problems and difficulties finding ways to help. To refreeze the entire Arctic shelf it would cost 500 billion USD and they need a lot of money to pay for it. Reducing greenhouse gases can affect that. Some things that you can do to help reduce greenhouse gases is to finding other gases that can help. That is how you can help reduce greenhouse gases and why it's difficult to cut back on greenhouse gases.

It is hard to cut back on the greenhouse gases because Julienne Stroeve says that it is because of global warming and global warming is causing by the increase carbon dioxide that she says can't be stopped. I think the only way we humans can stop the greenhouses gases is by not using motorized vehicles, powered factories, burning fossil fuels and so much more.

Awesome Job Ruby! It is amazing what we use these days for living and that could cause a lot as well. I love how you listed examples of how we can reduce the uses of greenhouse gases.

It is so difficult to cut back on greenhouse gases because we need them here on earth. The ways we have tried to get rid of them didn't work and now we still have them today. Scientist might try using pumps in the future but that might not work. They have already tried artificial whitening of the poles by spraying aerosol particles to reflect sunlight back into the atmosphere and creating artificial clouds to stop the sunlight from reaching the surface altogether. It hasn't worked becasue of the outrageous amounts of money included in it. If we don't fix it soon bad things might happen. We also use gases and that is a part of most of the people's lives here so it is hard to take it away. Some things that we could do to reduce greenhouse gases is we could stop using vehicles, factories, and other gases as much in your lives so there won't be so much gas overall.

Why it is so difficult for humans to cut back on greenhouse gases is becuase they use it for so many things that they have gotten used to and don't plan on cutting back on. Also becuase we need them and people are just abusing how many of those gases they release into the air. Also more things are releasing greenhouse gases like water vapor, a powerful greenhouse gas, is being returned to the skies. So there is more and more of this gas therefore making it harder for people to get rid of it and also the fact that they think they need it when it is kind of destructive. Some things that you can do to help reduce greenhouse gases is to close down factories that produce harmful gases and put in other energy production factories that release less harmful gases into the air. Also stopping to put all harmful gases in the air by informing people what is harmful and what isn't becuase most people don't know how greenhouse gases are destroying a lot of things.

It is hard to cut back on greenhouse gasses because in our world today we use a lot of Carbon Dioxide which is a cause of Greenhouse gases it's hard to keep away a lot of it since so much is being made. Some things that you can do to hep reduce greenhouse gases is by using less heat/air conditioning and by buying energy efficient products.

It is hard to cut down on greenhouse gasses because a lot of these gasses we use in our everyday things! We can cut down on greenhouse gasses by using other products for a while. We could also try to make substitutes for these gasses so that way we aren't without too many things.

Good Job Bijou! I like how you said that there could be a substitute or replacement for the gases besides the greenhouse gases. We could also do that with other daily life objects as well.

The reason it it so hard to reduce greenhouse gasses is because some people don't know what it could cause or don't care. The main reason is that people are relying more on cars and machinery that emits carbon dioxide. Somethings that I can do are I can raise awareness or I could simply walk or ride my bike instead of riding in a car. I can also try carpooling to reduce the amount that is being released.

If ice is melting that would be a bad thing because there are a lot of animals that live in the Arctic that will end up with no home, it also is bad because ice regulates the temperature of the world so it won't be too hot or too cold.

It so difficult for humans to cut back on greenhouse gases because the first reason is scientists are still trying to come up with ways to reduce greenhouse gases. It is not all there fault but they are still worrying and hurrying to find another solution. The second reason is Desch thought of a good idea to make the ice thicker but the researchers estimated that in order for them to make the ice thicker they would need about 10 million pumps. Adding to the 10 million pumps is at least $50 billion US dollars. For the whole project it would add up to $500 billion dollars! That is a lot of time and money spent on this project that they are working on for the greenhouse gases. The third reason why it is difficult is because it will take a decade to restore the ice entirely. The last reason is it will be a lot of hard work to get people who do that sort of job for living. Also the safeties of doing that as well.

I think that it's difficult for humans to cut back on greenhouse gases because it's still useful to us in ways. Taking it away or shortening it, would cause a few things. It can also be difficult for people to cut back greenhouse gases because probably not everybody knows what it can do to the polar ice caps. It potentially makes the situation worse. To reduce greenhouse gases, we should first start by showing people what the situation is and what is needed to be done. We probably also have to convince, or try our best to shorten the greenhouse gases as soon as possible, and show this to the public.

It is so difficult for humans to cut back on greenhouse gases because there are already too many factories in that world and people are building more and more. Another reason why it's so difficult for humans to cut back on greenhouse gases because there's already so much being released every day, that there's basically nothing we can do about it anymore. The effects are irreversible.

It is so hard for humans to cut back on green house gasses because it is already a part of our everyday lives. What I mean by this is a lot of the greenhouse gasses come from factories, but you can't shut down the factories because people work there and they will lose there job which will create another problem. They also can't cut down on greenhouse gasses because think about it, there has been so much chemicals that have been collecting up in the atmosphere that it is very unlikely for someone to stop that. What we need to do to help reduce greenhouse gasses is get the word out. If people see this and see how badly things can get they will help by cutting down on greenhouse gasses.

I think that it is hard for us to cut back on greenhouse gasses becasue we use them for cars and that is how we get places. I think that it is a better idea to use electric cars so that way it will not hurt our home. Some things that we can do to reduce greenhouse gasses is to take the bus and carpool. This would be a better idea because that way we would use less gas.

I agree with you Matthew because people use cars everyday to go to work and more. It can harm people if they stop using cars.

It is so difficult for humans to cut back on greenhouse gases because without them there would be no life on earth. Without greenhouse gases Earth would be too cold to live so that is why. The earth would freeze without greenhouse gases so that is why it is so difficult to cut back on greenhouse gases.

I think it is hard to cut back green house gasses because we use them for everyday things and if we didn't have them we couldn't have as much things as we do today.

It is so hard for people to stop using greenhouse gases because they have got so accustomed to it. If we stop, it would be harder to find ways to go along with our lives. This is why we have Daylight Saving and Earth Day. One way we can stop using these gasses is by stop using electricity for a day or so. I know this is basically Earth Day, but we can still do it in a different part of the year.

It is hard to help refreeze the Arctic because if the Arctic is cold again. It can melt again in the summer and then you will have to refreeze again. Which means that you will need to get more money again too.

Somethings we can do to reduce usage of greenhouse gasses is try to find ways to do what we use greenhouse gasses for but with different substances. Instead of using gasoline as a fuel source people can get electric cars to drive or get solar panels. This would reduce the carbon dioxide going into the air.
