    When the research team modeled a scenario where temperatures never dropped back below 1.5 °C by 2100, they found that at least one of Earth’s four major systems, or tipping elements, was triggered in roughly 24% of simulations.

    An even grimmer scenario – where temperatures peaked near 3 °C before gradually declining – resulted in a 45% chance of triggering a permanent shift by 2300.

    “Sticking to current policies could lock us into a 45% chance of triggering irreversible changes by 2300 – even if we later bring temperatures back below 1.5 °C after a temporary overshoot.”
