Despite international commitments like the Paris Agreement, global efforts to curb climate change are facing significant challenges. Recent COP30 negotiations reveal that many countries are falling short of their targets, and emissions continue to rise. This raises important questions about whether current strategies are enough and what the future holds for climate action. Below, we explore key issues such as overshoot, scientific warnings, and how world leaders are responding to this urgent crisis.
-
What does overshoot mean for climate targets?
Overshoot refers to exceeding the 1.5°C temperature rise limit set by climate agreements. Scientists warn that due to current emissions trends, overshoot is now inevitable, meaning temperatures will temporarily go above the target before efforts to reduce emissions bring them back down. This can increase the risk of crossing dangerous tipping points, like melting ice sheets or drying rainforests.
-
Are global efforts to limit warming working?
Overall, global efforts are not yet enough to meet the 1.5°C goal. Despite commitments, emissions continue to rise, and current policies project a temperature increase of around 2.8°C by the end of the century. While some countries are making progress, the collective effort falls short, making the goal of limiting warming increasingly difficult.
-
What are scientists saying about climate risks now?
Scientists warn that crossing the overshoot threshold could trigger irreversible changes, such as the loss of the Amazon rainforest or the melting of major ice sheets. They emphasize that the risks of climate tipping points are higher than ever, and urgent action is needed to prevent catastrophic impacts on ecosystems and human societies.

How are world leaders addressing climate change today?
At COP30, many leaders acknowledged the challenges but also highlighted the need for stronger commitments and innovative solutions. However, some major nations, like the US, were absent from negotiations, complicating global efforts. The focus is now on accelerating technological advancements and natural carbon removal to manage overshoot risks.
-
What is the significance of rising emissions despite climate talks?
Rising emissions indicate that current policies and commitments are insufficient. Despite international agreements, economic growth and energy demands continue to drive emissions upward. This underscores the urgent need for more aggressive action and global cooperation to effectively combat climate change.
-
Can technological solutions help us stay below 1.5°C?
Technological solutions like carbon capture and geoengineering are being explored as ways to reduce atmospheric CO2. While promising, these methods are still in development and face uncertainties. Relying solely on technology without reducing emissions may not be enough to prevent overshoot and its associated risks.
