Climate scientist Dr. Thomas Lee argues that climate tipping points could trigger rapid, irreversible changes much faster than gradual projections.

readingWhich evidence would best support Lee's tipping point concern?
A
Temperatures have increased
B
Climate models include many variables
C
Ice core data shows past climate shifts occurred in just 10 years when thresholds crossed; Arctic ice melted 100x faster than linear models predicted
D
Scientists study climate change
Correct Answer: C
Choice C is the best answer. Historical rapid shifts + current nonlinear acceleration proves tipping points are real.
💡 Strategy: Tipping point claims need evidence of nonlinear acceleration.
