Question

The burning of fuel releases carbon dioxide. Based on the current rate at which humans burn fossil fuel, a theoretical 8 PgC should be released into the atmosphere annually. How does this number compare with those from the simulation?

Answer 1

The burning of fossil fuels releases a significant amount of CO2, enhancing the greenhouse effect and contributing to climate change. The current rate of fossil fuel use, releasing 8 PgC annually, is causing atmospheric CO2 to increase, which is confirmed by simulations and observable data.

Step-by-step explanation:

The burning of fossil fuels releases carbon dioxide (CO2) into the atmosphere, contributing to the greenhouse effect and climate change.

The mentioned simulation suggests that at the current rate of fossil fuel use, an annual release of 8 PgC (Petagrams of carbon) would significantly increase atmospheric CO2. This increase is compared to a theoretical scenario where CO2 emissions would drop to 1.8 ppm/year if fossil fuel use was replaced instantly.

However, even with this reduction,continued use of fossil fuels at today's levels would result in a substantial rise in atmospheric CO2 by 2100.

Human activities, including the burning of fossil fuels and deforestation, are causing atmospheric CO2 levels to rise, which exacerbates global warming.
