Multiple Choice Questions
- Base Period for Climate Change Comparison: The base period used to compare annual average temperature changes is 1901-2000.
- Argo Floats: Argo floats measure ocean temperatures at various depths.
- Milankovitch Cycles and Climate Change: Milankovitch cycles influence climate change by affecting the distribution of solar radiation due to changes in Earth's orbit and tilt.
- Surface Ocean Currents: Surface ocean currents are driven by wind and the Coriolis effect.
- Positive Feedback Loop and Ice Reflectivity: A positive feedback loop amplifies climate change by decreasing ice reflectivity.
- Greenhouse Gas Heat Trapping: Greenhouse gases trap heat by absorbing and re-emitting infrared radiation.
- U.S. Greenhouse Gas Emissions from Transportation: Transportation accounts for approximately 25% of U.S. greenhouse gas emissions.
- Ocean Acidification and Marine Organisms: Ocean acidification harms marine organisms with calcium carbonate shells.
- Sea Level Rise Cause: Sea level rise is primarily caused by the thermal expansion of seawater and melting ice sheets.
- Climate Tipping Points: A significant concern of climate tipping points is sudden and irreversible changes in climate systems.
- El Niño and Global Weather Patterns: El Niño events bring warmer water and disrupt normal currents, affecting global weather patterns.
- Paleoclimate Proxies (Tree Rings): Tree rings provide evidence of past climate conditions.
- Atmospheric Carbon Dioxide Increase Since Industrial Revolution: Atmospheric carbon dioxide has increased by over 100 ppm since the Industrial Revolution.
- Greenhouse Gas with Highest Warming Potential (Compared to CO2): Chlorofluorocarbons (CFCs) have a higher warming potential than carbon dioxide.
- Extreme Weather Events and Climate Change Effects: Extreme weather events cause altered precipitation patterns and prolonged droughts.
True/False Questions
- Climate Change and Global Heat Distribution: Climate change affects global heat distribution by altering ocean currents. (True)

- Nitrous Oxide Emissions and Human Activity: Human activities have increased nitrous oxide emissions, mainly from fertilizers. (True)
- Gulf Stream and Thermohaline Circulation: The Gulf Stream, a part of the thermohaline circulation, keeps northern Europe warmer. (True)
- Extreme Heatwaves and Climate Change: Extreme heatwaves are becoming more frequent due to climate change. (True)
- Paleoclimate Proxies (Coral & Ice): Coral skeletons and ice cores are both examples of paleoclimate proxies. (True)
- Sea Level Rise and High-Altitude Regions: Rising sea levels disproportionately affect low-lying coastal areas, not high-altitude regions. (False)
