Drainage basin is an area where all surface water converges to a single point. Separated from adjacent basins by drainage divide made of elevated features. May consist of smaller basins merging at river confluences
Atmospheric methane concentration has increased 160% since 1750. Global methane levels reached 1866 ppb in 2019, highest in 800,000 years. Methane contributes 23% of climate forcing and 3% of total GHG emissions
Floodplains are land adjacent to rivers, extending from banks to valley base. Formed through deposition on river meanders and overbank flow. Sedimentation rates range from 0.57 to 1.0 kg/m² during floods. Natural levees and crevasses develop from overbank flow
SBTN establishes scientific objectives for nature conservation and restoration. Framework aligns corporate actions with planetary limitations. Recognizes overlap between climate and natural systems
Air mass circulation controls Europe's climate, especially Atlantic air masses. Five major pressure belts control air mass movement across Europe. Winter westerlies bring warm tropical air, summer westerlies bring Arctic air
Greenhouse gases trap infrared radiation, contributing to Earth's greenhouse effect. Carbon dioxide, methane, and water vapour are the most important greenhouse gases. Greenhouse gases significantly affect Earth's energy budget despite being small
