The ocean has shielded us from the worst of climate change. Now it is running a fever

Nearly every indicator of climate change is flashing red. But we still hold the tools available to bring the planet back into balance

The ocean has shielded us from the worst of climate change. Now it is running a fever

TL;DR

  • Marine heatwaves have tripled since the early 1990s, causing significant damage to marine ecosystems.
  • The ocean has absorbed over 90% of the excess heat trapped by human activity.
  • The Earth's energy imbalance, the gap between incoming solar energy and outgoing radiated energy, has more than doubled since the late 20th century.
  • Human-induced warming has reached approximately 1.37C above pre-industrial levels.
  • The rate of sea-level rise has more than doubled in recent decades, reaching a new record of 23cm since 1901.
  • Monitoring systems for ocean and Earth's energy imbalance are being scaled back, threatening our ability to track climate change.
  • Despite the dire indicators, human activity can still work to bring the planet back into balance.
