Thirty billion tons of carbon dioxide is found in the air from burning fossil fuel every year. Half remain in the air while the other half disappears. The NANA satellite scheduled to be launched on Tuesday will help to understand the goings of carbon dioxide. Carbon dioxide is the main heat-trapping gas behind the warming of the planet.
The new data could help improve climate models and the understanding of carbon sinks what are oceans that absorb. Some year’s carbon dioxide stays in the air which indicates some of the sinks that absorb some of the carbon dioxide. There are variations each year so some years it will stay in the air and some years it will disappear. “Something out there is changing dramatically,” said David Crisp, a scientist at the NASA Jet Propulsion Laboratory in Pasadena, Calif., who is the principal investigator of the mission. Before the beginning of the Industrial revolution the CO2 levels were about 280 parts per million. The level is 387 parts per million today and is projected to rise sharply in the coming decades. Scientists have a good estimate about how much CO2 is being released because of the burning of fossil fuels but other human impacts like clearing forest and harvesting crops also affects CO2 but scientists yet know how.

This summary was very good. It was easy to read because it was easy to relate to. It was also very informative and not I known a lot more about carbon dioxide in the air than I did before. Finally, some else that was done well in this article summary was that it had a direct quote from a reliable source.
There are a few things that could be improved in this summary. For one thing there are a few grammatical errors. Another is that the article is strictly facts, which is good, but by adding a few interesting adjectives, and other things, it could be a little more enjoyable to read.
One thing I learned from reading this summary and the original article is that before the industrial revolution there was that the level of CO2 was about 280 parts per million. Today the level is 367 parts per million and is expected to rise sharply in the coming decades.
This article was a good choice because it is about an ongoing problem, so I found it interesting to read. This article was very effective in making me understand the problem pertaining to carbon dioxide because it explained the problem and how scientists are making an effort to investigate the problem further. Lastly, he addressed a certain period that most likely had the most harmful effect on raising rates of carbon dioxide in the atmosphere.
However, there was room for improvement in this summary. When he talked about sinks, I was confused at to whether he meant the carbon dioxide is sinking, or if there was another meaning for it. Also, he could have talked about the industrial revolution earlier in the article to inform the readers about a critical turning point in the carbon dioxide levels in the atmosphere.
One new fact I learned in this summary was that there are variations in the carbon levels in the atmosphere each year, and often a lot of carbon dioxide disappears.
1. Used a interesting artical that few knbow abouut
2. Had interesting and well thought out facts inorder to show the importance of this artical.
3. It was also good how he showed what could happen if this problem is not meet head on.
1. I didn't think that he explained this artical as easly as he could have.
2. I didn't like how he didn't give a history of the primary scientist who discovered this information.
1. One thing that helped me understand this artical was that Thirty billion tons of carbon dioxide is found in the air from burning fossil fuel every year.
The article was a nice choice and was presented very well in the summary. The article appealed for reasons such that it applies to us and affects us. It has expanded my knowledge about carbon dioxide. The problem was stated and explained in the summary.
Although the summary was nicely said, there was too much fact to it. Saying more than facts would have been a better thing to do. Also the simple errors such as gramatical ones could've been avoided in order to help me read the summary easier.
From the summary i learned that there are different types of carbon dioxide in the atmosphere and most end up disappearing at some point.
3 aspects well presented:
* The issue has to do with the warming of the planet which today is a really interesting fact to talk about.
* Easy to comprehend by explaining very well the actions that the CO2 has in our planet.
* It helped me to understand better about the effects of carbon dioxide on Earth
2 suggestions:
* You could explain why just half of carbon dioxide remain in the air while the other half disappears.
* You could tell us about methods to revert the situation.
1 thing learned:
* I learned that is really important to be conscientious and use the methods that do not affect negatively the nature.
1. This article was interesting because the topic is a topic which discussed a lot today.
2. It was good how he talked about the results of this problem to inform us about it
3. easy to understand
1. very factual but too many facts without explanation
2. explain why some carbon dioxide disappears while some stays in the air
1. I learned that carbon dioxide sometimes disappears and i never knew that before.
3 Things Done Well:
1. The summary concisely summarized the issue.
2. The inclusion of a link to the article was helpful for further reading.
3. Included just enough specific information - just enough to detail the issue, but not enough to cause confusion.
2 Things needing improvement:
1. You could have explained the importance of the parts-per-billion figures, explaining what a level in the 300 means and what the ramifications of the other levels mention are.
2. You probably should have mentioned that the rocket which was to deliver this satellite blew up, destroying the satellite.
1 Thing I Learned:
1. I was unaware of the mystery CO2 escape phenomenon - very interesting.
1. -the article was very interesting and fascinating
-i liked how it talked about the earth and some of the problems it has with it
- the article was very easy to understand
2. -you could have explained the article a little more
-there were a few grammatical errors that could have made the article better
3. -i learned that there are many times of CO2 and that they don't stick around, as most people believe, they end up disappearing instead
1. very interesting
2. interesting facts
3. explained how to solve problem
1. didn't summarize well
2. didn't give much background information
1. I learned that thirty billion tons of carbon dioxide is found in the air from burning fossil fuel every year.
