Earth's Energy Crisis: Unprecedented Ocean Warming & Extreme Weather

The Earth's energy imbalance has reached a critical point, with the oceans absorbing most of the excess heat and experiencing the highest heat content in history. This is disrupting marine ecosystems, melting polar ice, and altering ocean currents, with far-reaching consequences for the planet and humanity.

Why it matters

The Earth's energy imbalance is a clear sign that we are destabilizing the planet, with the oceans bearing the brunt of the crisis. This has widespread implications, from faltering harvests and deadly heatwaves to extreme weather events, undermining our own survival.

The details

The oceans have absorbed over 90% of the excess heat trapped by greenhouse gases, with last year recording the highest heat content in history. This heat is disrupting marine ecosystems, melting polar ice, and altering ocean currents. Only 1% of the excess heat warms the Earth's surface, yet this tiny fraction is enough to make the past 11 years the hottest on record, highlighting the planet's sensitivity to even minor shifts in energy balance.

• Last year, the Earth's energy imbalance more than doubled the average rate.
• The transition from La Niña to El Niño by the end of this year could push global temperatures to record levels.

What’s next

The Earth's energy imbalance is a long-term problem that will outlast civilizations, as much of the heat is moving into the ocean depths where it will linger for thousands of years. This raises the urgent need for immediate and sustained action to address the crisis.
