ESS 6.2.3 [AHL] Further about the Impacts of Climate Change
Learning Objectives Abstract Global climate models (GCMs) are sophisticated computational tools that simulate the Earth’s climate system by manipulating input variables and applying mathematical equations to represent the physical processes and interactions that drive climate dynamics. The reliability of these models is commonly evaluated through hindcasting, a method that compares simulated outputs with historical climate…

ESS 6.2.2 Impacts of Climate Change
Learning Objectives Climate Change and Carbon Cycles Anthropogenic emissions of greenhouse gases (GHGs) have intensified the natural greenhouse effect. Human activities have introduced substantial quantities of carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) into the atmosphere, alongside smaller amounts of other GHGs, contributing to global warming and climate change. In the absence of…

ESS 6.2.1 Evidence & Causes of Climate Change
Learning Objectives Abstract Climate is shaped by atmospheric physical processes, yet anthropogenic carbon dioxide emissions have driven a significant rise in atmospheric concentrations, with emission rates accelerating notably since 1950. Proxy records such as ice cores, tree rings, and sediments demonstrate a positive correlation between CO₂ levels and global temperatures, evidencing the enhanced greenhouse effect…
