So ranljivi zaradi podnebnih sprememb, saj se zaradi segrevanja oceanskih voda topi morski led, na katerem \u017eivijo in se razmno\u017eujejo. Zato je pomembno, da lahko spremljamo, koliko skupin pingvinov \u2013 imenovanih <i>kolonije<\/i> \u2013 obstajajo. To je te\u017eko, saj \u017eivijo v oddaljenih obmo\u010djih, kjer temperature padejo na mrzlih \u201350 \u00b0C, kar znanstvenikom ote\u017euje obisk teh obmo\u010dij.
