Speaking of altering the ecosystem, researchers are finding that climate change also affects cave biology. The dark zones of a cave have constant cool temperatures. Cave organisms have evolved over millions of years to adapt to this stability. If the planet's temperatures continue to ascend, scientists fear that many troglobites won't be able to adapt quickly enough to keep up (source.
