GLOBAL WARMING: The long-term increase in Earth’s average surface temperature, mainly due to human caused greenhouse gas emissions.
POSITIVE FEEDBACK LOOP: A process where an initial change triggers effects that amplify that change (e.g., melting ice reduces reflectivity, causing more warming and more melting).
EVAPOTRANSPIRATION: The combined process of water evaporating from land and transpiring (releasing moisture) from plants into the atmosphere.
URBAN HEAT ISLAND EFFECT: A phenomenon where cities and densely built urban areas become significantly warmer than nearby rural areas, especially at night, because of a lack of tree canopy and dark pavement.
GREEN INFRASTRUCTURE: Natural or nature-based systems (like parks, green roofs, wetlands) that manage water, reduce heat, and improve environmental quality.
GREY INFRASTRUCTURE: Traditional, engineered systems (like roads, pipes, sewers, and buildings) used for transportation, water, and other services.
