Question

true or false
the increase in carbon dioxide since the year 1860 is similar to past increases

Answer 1

False. The increase in carbon dioxide (CO2) levels since 1860 is not similar to past increases observed in geological history. Current CO2 levels, which have risen dramatically due to human activities such as burning fossil fuels and deforestation, are occurring at a much faster rate than natural increases in the past. Historical increases in CO2 over geological timescales were generally associated with natural events, such as volcanic eruptions or changes in Earth's orbit, and occurred over much longer timeframes. The rapid rise in CO2 levels since the industrial revolution is unprecedented in the context of the Earth's recent geological history.
