📖 1. Arctic Climate Change

🔑 Key Concepts & Definitions

• Greenhouse effect : Greenhouse effect is the warming process strengthened when greenhouse gases trap part of Earth’s outgoing heat and alter the natural climate cycle.
• Short-lived climate pollutants : Short-lived climate pollutants are atmospheric agents with brief lifetimes that still strongly affect climate during their persistence, such as methane and black carbon.
• Ice-albedo feedback : Ice-albedo feedback is a self-amplifying loop where loss of reflective ice and snow increases absorbed energy, raising temperatures further.
• Permafrost : Permafrost is ground that stays below 0°C for at least 2 years and can act as a long-term carbon storage.
• Rapid Arctic warming : Rapid Arctic warming is the observed pattern that the Arctic warms faster than the global average, especially after 2005.
