When Will Climate Change Be Irreversible? (And What the Science Says Now)
Climate change becomes irreversible when Earth’s systems cross critical thresholds called tipping points, triggering self-perpetuating changes that continue even if we stop emitting greenhouse gases. These aren’t distant hypotheticals. At 1.4°C of global warming, warm water coral reefs are already crossing their thermal tipping point and experiencing unprecedented dieback that cannot be undone within human timescales.
The question isn’t whether we’ll face irreversible changes. We’re witnessing them now. The real question is how many more tipping points we’ll cross and whether we can prevent the most catastrophic …
