Earth System Telemetry & Climate Dashboard
Track 9 planetary vital signs across atmospheric greenhouse forcing, surface temperature anomalies, ENSO ocean-atmosphere oscillation, polar cryosphere ice balance, and deep-ocean heat uptake—paired with linked research dispatches and encyclopedia primers.
🌍 Understanding the 9 Planetary Vital Signs
Earth's climate system is governed by the radiative energy balance at the top of the atmosphere ($N = F - \lambda \Delta T$). When greenhouse gas concentrations rise, outgoing longwave infrared radiation is trapped, creating a positive Earth Energy Imbalance that partitions heat across the atmosphere, cryosphere, and global oceans.
🌡️ 1. Surface Thermal & ENSO Dynamics
ERA5 2m Mean Temperature and NASA GISTEMP v4 measure global air and sea-surface warming against pre-industrial (1850–1900) and modern (1991–2020) baselines, while the Niño 3.4 Index tracks internal tropical Pacific heat redistribution between El Niño and La Niña phases.
❄️ 2. Carbon Forcing & Ice-Albedo Feedback
Mauna Loa CO₂ exceeds 425 ppm—over 50% above pre-industrial levels (~280 ppm)—driving logarithmic radiative forcing ($\Delta F = 5.35 \ln(C/C_0)$). As Arctic & Global Sea Ice thin and retreat, reflective white ice ($a \approx 0.6\text{–}0.85$) is replaced by dark open seawater ($a \approx 0.06$), amplifying polar warming.
🌊 3. Ocean Heat, Sea Level & Acidification
Over 90% of Earth's excess heat is absorbed by the upper 2,000 meters of the ocean, driving thermal expansion (steric sea level rise) alongside land-ice melt. Simultaneously, oceanic uptake of ~25–30% of anthropogenic CO₂ forms carbonic acid ($\text{H}_2\text{CO}_3$), lowering surface pH and aragonite saturation.
