On 24 October (that's today!!), people in 181 countries are coming together for the most widespread day of environmental action in the planet's history. At over 5200 events around the world, people are gathering to call for strong action and bold leadership on the climate crisis.What does the number 350 mean?
350 is the most important number in the world...it's what scientists say is the safe upper limit for carbon dioxide in the atmosphere.Two years ago, after leading climatologists observed rapid ice melt in the Arctic and other frightening signs of climate change, they issued a series of studies showing that the planet faced both human and natural disaster if atmospheric concentrations of CO2 remained above 350 ppm.
Everyone has now embraced this goal as necessary for stabilizing the planet and preventing complete disaster. Now the trick is getting our leaders to pay attention and craft policies that will put the world on track to get to 350.이산화탄소 농도를 350 ppm으로!!
이산화탄소 농도를 현재의 387 ppm에서 350 ppm으로 안정화시키자는 취지의 "350 환경캠페인"이 오늘2009년 10월 24일에 전세계 6대륙에서 동시에 열리고 있읍니다.
