Answer:
True.
Step-by-step explanation:
There is a scientific consensus that the increase in carbon dioxide (CO2) in the Earth's atmosphere, primarily due to human activities such as burning fossil fuels and deforestation, is contributing to the warming of the planet through the greenhouse effect. Carbon dioxide is a greenhouse gas, meaning it traps heat in the atmosphere, which can lead to higher temperatures on Earth. This phenomenon has been observed through various scientific measurements, including the rise in global average surface temperature and the increase in ocean temperatures.
