The current data indicate that the record high global temperatures of the past two decades correspond to record high atmospheric CO₂.

Question

Quizplus · Accepted Answer

The statement is true. There is a well-established scientific consensus that the record high global temperatures observed in recent decades are largely due to the increase in atmospheric CO2 levels caused by human activities such as burning fossil fuels. This relationship between CO2 and global temperature is supported by multiple lines of evidence, including direct measurements of atmospheric CO2 and temperature, as well as proxy data from sources such as ice cores and tree rings.
