• Find a graph showing either global temperature or carbon dioxide concentration.  Post it on your blog.  Then, answer the following questions about it:
• What is the horizontal scale of your graph?  How many years does it show? It is vertical and it goes for 120 years.
• What is the vertical axis showing?  What are the units?  What is the total range shown? It show's temperature anomaly. The units go up by .2 and the total range is -.4 to .6
• Can you tell from the picture's host page where the data came from?  If so, where?  I don't know where it came from.

• 1 - What do you think the global average temperature is?  This means the average for everywhere on Earth, day and night, for an entire year.  Explain why you answered what you did.

I think the average temperature is around 50 degrees because some parts its really cold like 20 degrees and some parts are 100+ degrees.

• 2 - People are often talking about "global warming."  How much do you think the average global temperature has increased in the past 100 years?  Do you think that this is a lot?

I think the average global temperature has raised about 20 degrees.

• 3 - What do you think is the hottest the Earth has ever been? (since there has been an atmosphere?)  How about the coldest the Earth has ever been?  Explain why you answered what you did.

The ice age was when the world was the coldest and when a meteor hit the world that was the hottest.

• 4 - Are you concerned about "global warming?"  Why or why not?

No I am not because it doesn't concern me.

Guilty parties for oil spill

I feel the main reason for the oil spill was the person who originally made the machine. The break valves should have work and not malfunctioned and none of that would have happened. So it really lies on the person's shoulders who made it

fossil fuel

Coal is called a fossil fuel because it was formed from the remains of vegetation that grew as long as 400 million years ago. Coal is made of old vegetation that was buried for very long. it was heated so much to turn into that hard rock like shape.
