Fact #2

CO2 levels going up

- This source isn't very credible because we don't know who it is by. If the site had the name or what they did for a living then it would be a credible source.
- This source talks about the CO2 levels rising up because of human activities. The CO2 levels are rising extremely since 1750 which is the beginning of the Industrial Revolution.
- It is hard to say that I believe this source because it does not have a writers name or the writers occupation but I would say this is believable.

- Credentials- Science Daily
- This source is credible because it's a news page just for scientific things and telling us what's going on that other people may not know about.
- This source talks about how if the CO2 levels keep rising it will impact the coral reef.
- I believe this because the man made problem is us putting more CO2 into the atmosphere and the main reason why the coral reef is in danger is because of our mistakes and harming the world with the rising of CO2 levels.

By: Michael McCarthy
- Credentials- The Independent
- This source is credible because it was written by an environment editor. The part that is hard to give credibility is that it was written in 2004.
- This source talks about how CO2 levels rise may speed up global warming.
- I believe this site because it talks about how the CO2 levels rise could speed up global warming and I believe it because CO2 is the greenhouse gas which is effecting our atmosphere.
