active language in template.php

Quick and simple:
is there a way to get the active language user is viewing site in
template.php, sth like $language->language in page.tpl.php?

I want to use it in a condition like this:
function rouzdarou_breadcrumb($breadcrumb) {

if(arg(0) == 'news'){
  global $base_url;
  if($language->language=='en'):
    $breadcrumb[0] = l('Home', $base_url);
    $breadcrumb[1] = l('News', 'news');
  endif;
}
 return theme_breadcrumb($breadcrumb);
}


but dsm($language->language); returns nothing in template.php. If any1 knows
another way to achieve this share :)
Thanks in advanced.
