The CO2 concentration is higher in the northern hemisphere due to a variety of factors, including the larger amount of landmass, higher population density, and industrialization. These factors contribute to higher levels of carbon emissions, which ultimately increase the CO2 concentration in the atmosphere.
The fluctuations in CO2 concentration in the northern hemisphere are primarily influenced by seasonal changes. During the winter, plants and trees go into dormancy, resulting in less absorption of CO2 through photosynthesis. Additionally, human activities such as heating and increased energy usage during colder months can also contribute to higher CO2 levels.
Volcanic eruptions can have a temporary impact on CO2 concentration in the northern hemisphere. The ash and gases released during an eruption can block sunlight and lower temperatures, resulting in reduced plant growth and CO2 absorption. However, this effect is short-lived and does not significantly impact the overall trend of increasing CO2 levels.
No, the erratic CO2 concentration in the northern hemisphere has been observed for decades. However, with the increase in human activities and carbon emissions, the fluctuations have become more pronounced and the overall trend of rising CO2 levels has become more concerning.
The higher CO2 concentration in the northern hemisphere contributes significantly to global climate change. CO2 is a greenhouse gas, meaning it traps heat in the Earth's atmosphere, leading to rising global temperatures. As the CO2 concentration in the north continues to increase, it will have a significant impact on the Earth's climate, resulting in more frequent and severe weather events, rising sea levels, and other consequences.
