A rise of just 1°C or 2°C may sound small — but for the Earth’s climate system, it represents an enormous increase in trapped heat energy.
That extra heat influences everything from stronger heatwaves and melting ice to changing rainfall patterns and warming oceans. Climate change isn’t only about hotter weather — it’s about how interconnected systems across the planet respond to even small shifts in temperature.
Understanding that scale helps explain why scientists are deeply concerned about “small” temperature increases.
