Tuvalu, the fourth smallest nation on the planet, has announced it aims to be totally powered by renewable energy sources by 2020. Located between Hawaii and Australia, the tiny Pacific nation is one of the world’s climate change hotspots and many believe it is already seeing the negative affects of rising sea levels. The highest elevation on the island is just 4.5 meters (14.8 feet), and king tides have become increasingly damaging over the past 10 years, threatening the homes and livelihoods of its 12,000 inhabitants.
