Local Weather App completed and ready for review

Dear campers, i just finished my Local Weather App! It is quite simple. Any comments are welcome. And let me know if you see something in the code that can be improved. I will thank you a lot!

I have used these APIs:

Note: this app only works in http mode (http://codepen.io/…), not in https mode (https://codepen.io/…), since if I use “https://crossorigin.me/” (so I could run the app in https mode) in the geolocation API, it always returns the coordinates of New York.
