A volcanic1 eruption2 near Bali. This is a popular resort3 island in the pacific island country of Indonesia. That's key here. Because even though this eruption of Mount4 Jali wasn't actually on Bali, the wind blew its volcanic ash toward5 the island. And even though the eruption wasn't a major threat to people on the ground, it is to planes in the air. Volcanic ash can melt if it's stuck in an aircrafts' engines. It turns into a glasslike substance that can cause them to lose power and break down. So from Tuesday night until today, around seven hundred flights in the region6 were cancelled, leaving people stranded7 either unable to leave Bali or unable to get there.
Ice in the Antactica. There's a lot of it. That doesn't sound much like breaking news. But new information suggests it's increasing. That's puzzling scientists because research over the last ten years suggested that Antactica is losing ice and the melting is contributing to rising sea levels. Last year NASA reported that Antactica's sea ice reached a new record size. Now it looks like the continent's ice sheet is growing.
We know the sea levels around the world are rising and current thinking is that part of that sea level rise comes from melting ice in Antactica. But one recent study from NASA scientists says that may not be the case. Antarctica is a big place, roughtly the size of the US and Mexico combined. So as you might expect, changes in its ice are not uniform across the entire continent. Nearly all scientists agree that ice is being lost from the western part of Antarctica and along its
peninsula8. On the eastern side ices are actually being gained. But where the study is different is they measured the gaining of ice along eastern Antarctica is outpacing the loss on the western side. What's behind this addition of ice is snowfalls that started becoming heavier around ten thousand years ago. The scientists noticed this by looking into the ice
core9 data. Why is this important? It would mean that Antarctica is not contributing to sea level rise. Bottom line: There is still a lot we need to learn about how Antarctica is reacting to climate change.
