Humans Role in Global Warming Practice Test

Two nearby regions tracked changes from 1990–2020. Region X had rapidly growing fossil-fuel electricity use and rising CO$_2$ emissions. Region Y increased renewable electricity and its CO$_2$ emissions stayed about the same. Over the same period, both regions experienced rising average temperatures, and global sea level also rose. Which claim about humans’ role is best supported by using all the evidence (regional energy/emissions plus global climate indicators)?

A student argues: “Last winter was unusually cold where I live, so global warming cannot be happening, and human emissions don’t matter.” The class has long-term data showing (1) global CO$_2$ emissions increased from 1980–2020, (2) global average temperature increased over the same decades, and (3) global sea level rose over the same decades. Which claim is supported by the evidence?
