# Underfull warning [duplicate]

I get following underfull warning:

Underfull \hbox (badness 10000) in paragraph at lines 4--5

but can't find the solution. Here is my code:

\newpage
\thispagestyle{empty}

• Use the url package and embed the URLs as \url{www.cop21.gouv.fr/...} – egreg Feb 4 '16 at 10:22
• It is better to post a full minimal working example that starts with a \documentclass command, has a minimal preamble and then \begin{document}...\end{document}. Unless the problem is a compilation error, the code should compile and be as small as possible to demonstrate your problem. This makes it much easier for people to help you --- and much ore likely that they will! – Andrew Feb 4 '16 at 10:29
• are you sure it is from that code? 9999 times out of 10000 that warning is due to having \\  at the end of a paragraph, but there are no \\  here. It's possible that it is your url (you should do as egreg says and use url package in any case, for those) – David Carlisle Feb 4 '16 at 13:43
