Question

The increase in carbon dioxide since the year 1860 is similar to past increases.(1 point) Responses True True False False Question 4

Answer 1

False. The increase in carbon dioxide since the year 1860 is significantly higher and more rapid than past increases observed in the geological record. The current rise in CO2 levels is largely attributed to human activities, particularly the burning of fossil fuels and deforestation, which is unprecedented compared to natural variations in atmospheric CO2 levels in the past.
