Discussion Overview

The discussion revolves around the feedback loop involving carbon dioxide levels and ocean temperatures. Participants explore the cyclical relationship between increasing carbon dioxide, rising air and ocean temperatures, and the solubility of carbon dioxide in seawater. The focus includes understanding the dynamics of this feedback loop and the implications of positive versus negative feedback.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants describe a feedback loop where increased carbon dioxide leads to higher air and ocean temperatures, which in turn releases more carbon dioxide from seawater due to decreased solubility.
  • One participant expresses confusion about the positives and negatives in the feedback loop and seeks clarification.
  • Another participant suggests that the feedback process is cyclical and encourages others to label the direction of changes in quantities involved.
  • One participant proposes that the feedback is negative, although this claim is not universally accepted or confirmed.
  • Technical issues with displaying an attachment are noted, affecting the clarity of the discussion.

Areas of Agreement / Disagreement

Participants have not reached a consensus on whether the feedback is positive or negative, and there is ongoing uncertainty regarding the interpretation of the feedback loop's dynamics.

Contextual Notes

Participants express confusion about the representation of positives and negatives in the feedback loop, indicating potential limitations in understanding the underlying concepts. Technical issues with attachments may also hinder clarity in the discussion.

23. Feedback loops
a) As carbon dioxide levels increase in the atmosphere more outgoing infrared energy is absorbed which increases air temperatures and therefore ocean temperatures. As ocean temperatures increase carbon dioxide is released to the atmosphere because less carbon dioxide can be dissolved in seawater (i.e. the solubility of carbon dioxide decreases with higher temperatures). Draw the appropriate arrows between the boxes to complete the feedback loop described above.

I have attached what I think is the right way to display the feedback loop but I don't understand the positives and the negatives could someone explain

Welcome to the PF. Maybe try uploading the attachment again? I'm not seeing it.
 
I did its not showing my positives and negatives though
 
For some reason, in your original post, only the attachment thumbnail shows up, but when I click on the thumbnail, instead of getting an enlarged view, I just get a blank black screen. I was able to go into your original post and grab the URL for the attachment. This should display it directly in the post:

attachment.php?attachmentid=63660&stc=1&d=1383622904.png


Does that show up?

Regarding the actual question, what do you think is the relationship between these quantities. Hint: the process is cyclical, so just choose somewhere to start and go through the process, labelling the direction of the change in each quantity.

Another interesting question: is this positive or negative feedback?

I think its negative
 
Image is "black on transparent", and the background of attachment window is black, so the image is displayed black on black.
