Current Event: Tornado

     On Sunday, a tornado hit in Joplin Missouri. The tornado hit around 6:00PM and destroyed a hospital in it's path. The tornado also resulted in many people losing phone connection and electricity. 30 people were killed and about 11 bodies were recovered from one location. The hospital that was affected had caught on fire, causing the patients to temporarily relocate across the street. The tornado was said to be an 8-9 on a scale of 1-10. It also damaged churches, grocery stores, schools, and other buildings.
     I think that people should be more prepared for disasters like these because you never know when they'll happen, how fast they'll happen, or how severe they'll be. I also think people should be warned sooner, which might help them brace get themselves together before it hits; They'll be more ready.

1) What do you think the global average temperature is?
-I think it would probably be around 40-50 degrees because there aren't may hot places besides the equator. Plus you have to consider all of the seasons in each place.

2) How much do you think the average global temperature has increased over the past 100 years?
-I think it has risen a few degrees, about 10 at the most. I doubt it's really that much.

3) How hot/cold do you think the earth has ever been?
- I think the earth has reached 80, I'm not really sure why though. Just a wild guess. And maybe about, 20-30 for coldest.

4) I am not concerned about global warming, if nothing has happened by now then it most likely won't.
