As climate change legislation gains momentum in the U.S. government, evidence continues to arise that supports scientists' claims of human-caused climate change. What is your initial reaction to the podcast and news article? Which did you like better and why? What evidence, facts or information were most interesting to you and why?

That CO2 actually effects the ocean is not good at all i thought it just went up and hurt the ozone not the ocean aswell. I liked the Podcast better because I didn't have to read anything:). That the Bearing Sea is the body of water that the US gains most money in fish caught and how cold water is more acceptable to get acidic faster also with the fresh water running into the ocean distrubs it even more. Really liked the Podcast!

My initial reaction to the podcast was one of sadness. It was bad enough when I saw pictures of polar bears floating on ice broken off of the ice caps, now knowing that human CO2 production can harm oceanic environments makes me more willing to change my ways and educate others to change their ways. I liked the news article better because I felt it had more significant information relevant to the global warming "debate." I am glad we now know there is a link between elevated carbon dioxide levels and an absence of polar ice caps. This article seems to take some of the political opinion out of a scientific problem.
I too was unaware of the effect co2 had on the ocean. It also shocks me to hear that the ocean and ozone are to be destroyed and depleted within shorter and shorter timeframes as it goes on. I hope we are able to turn it around soon, for people and animals alike.
and i REALLY hope these comments boxes allow neon green text. :D
I think its amazing how much we've increased the amount of CO2 on Earth. I liked the news article better then the podcast, because it was more interesting, I guess and it the way they collected data was cool, I mean the walruses from the podcast were cool but they can't out rank ice . I think the fact of collecting ice chuncks from 22 million years ago is simply amazing. It's super cool that they can see the CO2 levels from those periods of when dino's were alive... scary.
Katelynn, just a couple of things to clarify. 20 million years ago the dinosaurs were long extinct, although creatures resembling them and not resembling much like what we see today did dominate the earth. Secondly, the scientists were looking at mud deposits on the ocean floor not ice chunks. Previous to this work, we only knew about CO2 levels because of ice cores, now we have "mud cores" that provide us with much more information.
My initial reactions two both the pod cast and news article was that this is horrifing and that we need to prevent this cause its not just sad but scary... i don't want to have my kids growing up in a place that u cant breathe in or cant eat something or cant drink the water because of this or that.
I liked them both because You got a better picture instead of just reading one thing... you got more and different information from both the pod cast and the news article.
From the article:
researchers used ocean sediments to plot CO2 levels back 20 million years.... I thought that was very interesting because thats very far back and its amazing that they can do that type of thing.
where historical temperatures and atmospheric content have left a series of chemical clues in the layers of ice.... I thought that this was very interesting because it helps scientist to understand what's happening and what's going to happen which is good so we have some understanding of what's going to happen to us in the future.
Co2 levels affect sea level.... interesting because that help us understand what's happening to the ocean and why

Within ten years its expected that maybe ten percent of the Arctic Ocean could become corrosive to shells and mussels and clams.... Interesting because thats not going to be good more the animals or us in time....
There's no quick fix.... thats scary cause i want to live.....
Even though the news article talks more generally about CO2 and the climate I liked the pod cast better. Not because i didn't have to read anything, but because i got better pictures in my mind of what is going on. Yes, the article gave facts such as higher temperatures of CO2 will not make our climate change in a period of time, but after a long time-scale, there could be a outrageous reaction that could hurt our oceans. However, the pod cast used statistics, which in my mind made the issue jump out more. Stating that in 10 years 10% of the Arctic Ocean could become corrosive to shells, mussels, and clams. Then it backs up that statistic by mentioning that without clams, shells, and mussels animals could not survive, Walruses eat approximately 100 pounds of clams a day. There is a fear that animals could go extinct. The pod cast also stated that the Bearing Sea is the richest fishery within the United States, so the thought of that getting filled with CO2 could mean very bad things. Most importantly the pod cast states that there is no quick fix. Once an ocean becomes acidic, there is no easy way to clean it all out. Prevention is the only way to solve the problem. The fact that animals were talked about is what grabbed my attention. There is a problem and now we need to make an effort to prevent this problem.

I like this topic. Even i made presentation in Korea about limit CO2 using. so we ll sell and buy
using carbon dioxide using right. but i don't like both this article and podcast;;; because it is too hard understand and long at me.i think article give me it is significant you need more care about using Co2. but Podcast is more easy understanding at me. we need reduce using Co2. Global warming is severe than before. Average of temperature is decreasing now.and i also saw polar bear standing ice piece.it was so shocked at me. i didn't know that it caused like this situation. i felt warning myself. they can't live their site, they ll lost way......
we can't revive their site. so we need protect their place....
My initial reaction to the podcast/news report was that it was very surprising to see that the Co2 levels effected the ocean. I did not even realize that that was possible until i saw and read the news report. I liked the podcast better because i am more of a visual learner. It disappointed me to here that people and the way we are living was the cause for the problem. It would be nice to find some better way to handle our Co2 output in efforts to make the ocean and earth a better place.
