How close are the planet's climate tipping points?
Scientists warn that climate tipping points are imminent, risking ecosystems like coral reefs, permafrost, and ice sheets. Urgent action to reduce carbon emissions is essential to prevent irreversible changes.

The article discusses the imminent climate tipping points that could lead to irreversible changes in Earth's ecosystems due to global warming. Scientists warn that various natural systems, such as coral reefs, permafrost, and ice sheets, are approaching critical thresholds. For instance, coral reefs face severe bleaching, with predictions indicating that 70% to 90% of reef-building corals could die in the coming decades if warming continues. The thawing of permafrost poses another risk, as it releases significant amounts of greenhouse gases, further exacerbating climate change. The Greenland and West Antarctic ice sheets are also at risk of irreversible melting, which could significantly impact global sea levels and weather patterns. Additionally, shifts in the West African monsoon and the potential collapse of the Amazon rainforest could have dire consequences for biodiversity and human livelihoods. The article emphasizes the urgency of reducing carbon emissions to mitigate these risks, as the longer we delay action, the closer we get to these tipping points.
- Climate tipping points are approaching due to global warming.
- Coral reefs could see a 70% to 90% decline in reef-building corals in the coming decades.
- Thawing permafrost is releasing greenhouse gases, worsening climate change.
- Greenland and West Antarctic ice sheets are at risk of irreversible melting.
- Urgent action is needed to reduce carbon emissions to prevent reaching these tipping points.
