The concept of 'tipping points' in climate science refers to critical thresholds in Earth's systems that, once crossed, lead to significant and often irreversible changes. These thresholds are not merely linear extensions of gradual warming; rather, they represent abrupt shifts in state, such as the collapse of the West Antarctic Ice Sheet or the dieback of the Amazon rainforest. Recent research emphasizes that these tipping points are interconnected, meaning that crossing one may trigger others, creating a cascade effect. This interconnectedness poses a major challenge for mitigation efforts, as it implies that even if global temperatures are stabilized, the risk of crossing additional thresholds may persist. Consequently, scientists argue for urgent and preemptive action to avoid triggering these self-reinforcing feedback loops, which could fundamentally alter the planet's climate trajectory.
❓ Según el pasaje, ¿cuál es una implicación clave de la interconexión de los puntos de inflexión?
A. A) Estabilizar las temperaturas globales evitará automáticamente todos los puntos de inflexión.
B. B) Cruzar un punto de inflexión puede desencadenar un efecto dominó, lo que dificulta la mitigación.
C. C) Los puntos de inflexión son lineales y predecibles, por lo que pueden gestionarse fácilmente.
D. D) El colapso de la selva amazónica es el punto de inflexión más urgente que debe abordarse.
✅ 正确答案
B) Crossing one tipping point may lead to a domino effect, making mitigation more difficult.
IELTS Reading Tips
Skim the questions first, underline keywords, then locate in the passage
Watch for paraphrasing; correct answers are often reworded
Be wary of absolute statements (all, always, never) — usually wrong
Pay attention to content after transition words (however, but, yet)
