Worldwide Protest Launched Against Climate Change VOA News A day of worldwide protests against climate change is underway that organizers predict will draw more than one million participants, the largest-ever expected demonstration decrying the man-made causes of a warming planet. Friday's protests began across Asia, where hundreds of thousands of students and others took to the streets calling for action against climate change ahead of a United Nations summit on the issue. The protests later spread to Africa and Europe, with huge crowds filling the streets. In Australia alone, more than 300,000 children and adults rallied with the backing of some local authorities, schools and businesses. School Strike 4 Climate in Australia said the throngs of protestors represented the largest climate protest in the country's history. Warmer weather patterns have taken a toll on Australia, sparking drought, flooding, more intense brushfires and the whitening of the Great Barrier Reef. .
