Why do scientists think that the big increase in CO2 in our atmosphere is caused by humans?

• Because humans breath out CO2

• Because the big increase started at the same time the industrial revolution started - about 250 years ago.

What does this graph tell us?

• This graph tells us that CO2 has been blue for about 800,000 years
