1 GEOL 1330 Name: Damar Nunez Global Warming Lab #3 1. (20 points) Use the link below to watch a video about greenhouse gases. List the main greenhouse gases found in our atmosphere and summarize how they absorb heat radiation and what distinguishes them from the major gases in our atmosphere (N 2 and O 2 ). https://www.youtube.com/watch?time_continue=132&v=sTvqIijqvTg The atmosphere protects us by acting like a shield that blocks out harmful sun rays and also traps infrared heat aka heat which keeps the earths surface warm. Oxygen, nitrogen, water. O3, N2O, CO2 and methane. CO2 and methane spend most of their time “shaking it” in electrically- lopsided ways, allowing them to absorb infrared rays and help insulate the earth 2. (30 points) The more carbon dioxide and other greenhouse gases are present in the atmosphere, the more heat radiation is trapped in the atmosphere. The graph below shows measurements of carbon dioxide in the atmosphere from the Mauna Loa observatory on Hawai’i. Source: https://scripps.ucsd.edu/programs/keelingcurve/
2 How much does the amount of CO 2 vary over the course of one year? For a close-up look at one year go to the link listed above. 425-415=10. The CO2 varies by 10 ppm over the course of one year. Find the difference for a year high – low = answer Describe the pattern of this variation in one year. What might be the reason for this pattern? I think the reason for this pattern would be more plants in the spring vs in the winter, it would show higher CO2 concentration from like Jan-July because theres more plants , while in winter theres less plants. I would describe the pattern per year as kinda an “S” curve chart, it lower in Aug- Dec and then higher in Jan-July, and it repeats cause it happens every year but if I look at the two year tab it looks like a zigzag pattern in forming and then I if I look at the full record its clearly a zigzag pattern. What is the total change in the average CO 2 concentration since the beginning of this recording (1958) until now? 425-315= 110. The total change in the average CO2 concentration since 1958 to 2023 is 110 ppm. 3. (30 points) We need to examine the past to find out to what extent CO 2 levels have changed over time. We can use ice cores from Antarctica to understand past variations in trace gases. As snow falls it traps small amounts of air in the spaces between the snowflakes. Some of this gas forms small bubbles as the snow changes into glacial ice. The graph below ( https://climate.nasa.gov/vital-signs/carbon-dioxide/ ) shows the carbon dioxide concentration based on ice core data through the last approximately 800,000 years. What are the maximum and minimum CO 2 levels from 800,000 years ago until the year 1911, and what is the “natural range” (difference between max and min) in CO 2 during that time?
