: '''The Keeling Curve''' → The daily record of atmospheric CO2 since 1958; it shows a steady, terrifying rise.
: '''The Medieval Warm Period / Little Ice Age''' → Natural climate variations that help scientists calibrate their models.
: '''The 1.5°C Goal''' → The global target to avoid the most dangerous "Tipping Points."
: '''Negative Emissions''' → The theoretical need to not just stop polluting, but to actually suck CO2 out of the air (Direct Air Capture).
