Currnt Events
The Eyjafjallajokull volcano erupted in Iceland in 2004, but in 2010 the mountain was spewing out ash causing a hold up in air travel. The ash flowed about 15km in the air or about 9 miles. Volcanic activity is very common on this part of the planet because of the Mid-Atlantic Ridge. There were about 10 million air line travelers that were affected by the ash from Eyjafjallajokull. Some of the travelers said that the shur-down of the air lines was an over reaction to the ash.

Science Q's and A's
* 1 - I know that the temperature is higher than normal but I'm not sure of and exact number. It means that the tempetature is higher than normal and if affects everyone.
* 2 - Probably by some decimal.
* 3 - 90 degrees. -50 degrees. i said this because the hottest it has been is when there was no atmosphere, and the coldest because of the Antarctic.
* 4 - No because people have been talking about global warming for years and nothing has happened and when something does I will probably be dead.
