Historical Methane (CH 4 )<br />
Concentrations<br />
• The same bubbles used to get ancient air for CO 2<br />
measurements can be used to measure methane.<br />
• This plot is similar to the<br />
one above for CO 2<br />
except now we’re<br />
looking at methane.<br />
• You see the same rise<br />
in concentration at<br />
around 1800 when the<br />
industrial revolution was<br />
starting<br />
• Similar techniques used<br />
to measure CO 2 from the<br />
past are used to<br />
measure methane.<br />
