Nearly missed this! Sorry:)
' warming signs '.
^ if I'm correct, that is an excellent pun on global warming- or you've mistyped ' warning ', lol
Even if you have, I think ' warming signs' is just such an amazing title!
The content of the poem was interesting and I love how you've weeved facts into story.
The ryhming and wording I found was really smoothly executed. I especially enjoyed the second stanza. I love the word ' cherished' ,as it just seems to say everything, and in poems it sounds so soothing!
I loved this one and it has another great message :)
