175 400,000 300,000 200,000 100,000 Years Before Present 1. How much did the level of CO2 change between the last peak glaciation (~18,000 before the Industrial Revolution) and the start of the Industrial Revolution (-1850)? In other words, how much did the level of carbon dioxide change (in parts per million; ppm) between the bottom and middle circles above? 2. How many parts per million did the level of CO₂ increase per century over the 18,000-year period leading up to the Industrial Revolution? To do this, take 18,000 years and put it in centuries (100 years per century). Then divide your answer from Q1 by the number of centuries. 3. How much has the level of CO₂ increased from 1850 until present? (Top circle-middle circle) 4. How many parts per million (ppm) did the level increase per century over the last 172 years? 5. Take your rate of increase from Q4, and divide it by the rate of increase from Q2. Put the answer below. What you just figured out is how many times greater the current rate is compared to the natural background rate from the last glaciation until the start of the Industrial Revolution. 6. When I started teaching climate lectures in 2010, the level of CO₂ in the atmosphere was-385 ppm. How many times greater is the rate of increase from 2010 to present compared to the rate in Q2?

**Guide – Assignment 4: Climate Change – Rates of CO₂ Change** ### Graph: Atmospheric Carbon Dioxide The graph on the page shows the levels of atmospheric carbon dioxide over a time span of 400,000 years before the present, leading up to current levels. The data is sourced from Vostok Ice Core, Law Dome Ice Core, and Mauna Loa Instrumental Measurements. - **Y-axis**: Atmospheric Carbon Dioxide levels in parts per million (ppm). - **X-axis**: Years Before Present. The graph indicates: - A baseline level of around **180 ppm** during the last peak glaciation (~18,000 years ago). - An increase to **275 ppm** by the start of the Industrial Revolution (~1850). - A dramatic rise to a current level of approximately **420 ppm**. ### Questions for Analysis 1. **How much did the level of CO₂ change between the last peak glaciation (~18,000 years ago) and the start of the Industrial Revolution (~1850)?** - Calculate the difference in ppm between the initial value and the middle value on the graph. 2. **How many parts per million did the level of CO₂ increase per century over the 18,000-year period leading up to the Industrial Revolution?** - Convert the 18,000 years into centuries (18,000 / 100). - Divide the result from question 1 by the number of centuries. 3. **How much has the level of CO₂ increased from 1850 until present?** - Subtract the middle circle value from the top circle value on the graph. 4. **How many parts per million (ppm) did the level increase per century over the last 172 years?** - Perform a similar calculation as in question 2 for the period from 1850 to the present. 5. **Compare the current rate of increase to the historical rate prior to the Industrial Revolution.** - Divide the rate from question 4 by the rate from question 2. 6. **Consider CO₂ levels around 2010 (approximately 385 ppm). Calculate the rate from 2010 to the present. Compare with the historical rate.** - Use the graph to determine the increase from 2010 to the present. - Compare this modern rate with the historical rate calculated in question 2. These exercises will help identify and understand trends in atmospheric CO
