As global temperatures edge past critical thresholds, many experts warn that we are approaching a climate overshoot. But what exactly does this mean for the Earth, and how serious are the risks? In this page, we explore what climate overshoot is, why surpassing 1.5°C matters, and what can be done to manage this urgent issue. Keep reading to understand the implications and the actions needed to protect our future.

What does climate overshoot mean for the planet?
Climate overshoot occurs when global temperatures temporarily rise above the target limit, such as 1.5°C above preindustrial levels. This means the Earth experiences a period of higher-than-safe temperatures before efforts are made to bring temperatures back down. Overshoot can lead to irreversible changes in ecosystems, melting ice caps, and more extreme weather events.

Why is surpassing 1.5°C temperature increase a problem?
Exceeding 1.5°C increases the risk of severe climate impacts, including more intense storms, droughts, and rising sea levels. Scientific studies warn that crossing this threshold could trigger irreversible tipping points, like the collapse of vital ice sheets or shifts in ocean currents, which would make climate change much harder to control.
-
Can technological solutions reverse climate overshoot?
While technology offers promising tools such as carbon capture and geoengineering, these solutions are not yet proven at scale and come with risks. The best approach remains reducing emissions rapidly and naturally removing carbon from the atmosphere. Technology can help, but it cannot replace the need for immediate emission cuts.
-
What are the risks if global temperatures stay above the threshold?
If temperatures remain above safe limits, we face irreversible damage to ecosystems, loss of biodiversity, and increased human suffering. Critical infrastructure like coastal cities could be submerged, and food and water security could be severely threatened. Staying above the threshold amplifies the chances of crossing tipping points that could lock in catastrophic climate change.
-
Is it still possible to avoid the worst climate impacts?
Yes, but only if global efforts accelerate dramatically. Immediate action to cut emissions, invest in renewable energy, and develop natural carbon removal methods are essential. While overshoot is now seen as inevitable, managing it effectively can reduce long-term damage and help steer the planet back toward safer temperatures.
