☁️ Atmosphere & Climate

Part 1 of 7 — Greenhouse Effect, Climate Change, and Global Impacts


Atmospheric Composition

GasPercentageRole
Nitrogen (N2)(N_{2})78%Inert; cycled through nitrogen cycle
Oxygen (O2)(O_{2})21%Respiration; product of photosynthesis
Argon (Ar)0.93%Inert noble gas
Carbon dioxide (CO2)(CO_{2})0.042% (420 ppm)Major greenhouse gas; rising from fossil fuels
Methane (CH4)(CH_{4})Trace (~1.9 ppm)80x stronger GHG than CO2CO_{2} over 20 years
Nitrous oxide (N2O)(N_{2}O)Trace (~0.33 ppm)GHG from agriculture and fossil fuels
Water vapor (H2O)(H_{2}O)Variable (0-4%)Strongest natural greenhouse gas

The Greenhouse Effect

StepProcess
1Solar radiation (shortwave) passes through the atmosphere
2Earth absorbs solar energy and warms up
3Earth re-emits energy as infrared (longwave) radiation
4Greenhouse gases absorb and re-emit infrared radiation
5Heat is trapped, warming the lower atmosphere

🔑 The greenhouse effect is natural and necessary — without it, Earth would average -18C instead of +15C. The PROBLEM is the enhanced greenhouse effect from human emissions of CO2CO_{2}, CH4CH_{4}, and N2ON_{2}O.

Evidence of Climate Change

EvidenceObservation
Rising global temperature+1.1C since pre-industrial era
Sea level rise~3.6 mm/year (thermal expansion + ice melt)
Retreating glaciersNearly all major glaciers shrinking
Arctic sea ice decline13% decrease per decade since 1979
Ocean acidificationpH decreased by 0.1 units (30% more acidic)
Extreme weatherMore intense hurricanes, heat waves, droughts
CO2CO_{2} levels280 ppm (pre-industrial) to 420+ ppm (current)

Feedback Loops

TypeDefinitionExample
Positive feedbackChange amplifies itselfIce melting → less reflection → more absorption → more melting
Negative feedbackChange reduces itselfMore CO2CO_{2} → more plant growth → more CO2CO_{2} absorbed

Key Positive Feedback Loops

  1. Ice-albedo feedback: Melting ice exposes dark water/land → absorbs more heat → more melting
  2. Permafrost-methane feedback: Warming thaws permafrost → releases CH4CH_{4} → more warming → more thawing
  3. Water vapor feedback: Warming evaporates more water → water vapor traps more heat → more warming

Applied Recall ✍️

  1. Pre-industrial CO2CO_{2} levels were approximately _______ ppm; today they exceed 420 ppm.

  2. A feedback loop where change amplifies itself (like melting ice causing more warming) is called a _______ feedback loop.

  3. Oceans absorbing excess CO2CO_{2} causes ocean _______, which harms coral reefs and shellfish.

Classify the Concept 🔍

AP Exam Strategy: Atmosphere & Climate

  • Know the difference between the natural greenhouse effect and the enhanced greenhouse effect
  • Positive vs negative feedback — be able to identify and explain examples
  • Understand that CO2CO_{2} is the primary long-term driver even though CH4CH_{4} is more potent per molecule
  • Ocean acidification (CO2CO_{2} + H2OH_{2}O → carbonic acid) is a commonly tested topic separate from warming
  • Ice-albedo feedback is the most commonly tested positive feedback loop
  • Know the difference between weather (short-term) and climate (long-term patterns)
