Greenlanders Experience the Visible Effects of a Changing Climate

The population of Greenland is trying to deal with the effects of a warming planet. A changing climate has many benefits in the eyes of some Greenlanders. For instance, many new fisheries are open now that ocean temperatures are rising. Less ice means safer seas and also allows boats to fish closer to their own shores. In addition, changes in ocean temperature have expanded the ranges of many fish north to the waters around Greenland. Many fishermen are eagerly anticipating huge hauls of cod, which returned to Greenland's waters in 2006. Additionally, halibut, a stock traditionally found in the area, are increasing in size and, therefore, commercial value.
The warming has also made the climate in parts of Greenland

Interdependent marine ecosystem

An example from the seas (originally mentioned here years ago but removed because the link to the story no longer worked), was described by National Geographic Wild in a program called, A Life Among Whales (broadcast June 14, 2008).
It noted how a few decades ago, some fishermen campaigned for killing whales because they were threatening the fish supply and thus jobs.

TERUMBU KARANG TERANCAM

Dilihat dari hasil penelitian Global Coral Reef Monitoring Network menunjukkan bahwa, lebih dari dua pertiga terumbu karang diseluruh dunia telah rusak, bahkan terancam punah. Ancaman ini tak lain karena adanya pemanasan global yang tengah terjadi.

          Berbagai ancaman dapat beresiko bagi kelangsungan terumbu karang, misalnya pencemaran, penangkapan ikan berlebihan, kenaikan temperatur(pemanasan glonal), dan penggunaan sianida dan bom untuk menagkap ikan. Namun, pemanasan global yang disebabkan oleh aktivitas manusia adalah penyebab utamanya. Kenaikan suhu secara mendadak, walaupun kecil akan menyebabkan terumbu karang “memutih” karena lepasnya ganggang dari jaringan terumbu.

          Kepunahan terumbu karang akan merugikan ekonomi sebuah negara, seperti di Filipina dan Madlive. Sebab,
