why are scientists now more concerned about carbon dioxide as a greenhouse gas rather than methane for example?
many thanks,
many thanks,
Greenhouse gases are gases that trap heat in the Earth's atmosphere and contribute to global warming. They are concerning because they contribute to the Earth's rising temperatures, which can have harmful effects on the environment and human health.
CO2, or carbon dioxide, is a naturally occurring gas that is released through various human activities such as burning fossil fuels and deforestation. It is considered the most concerning greenhouse gas because it is the most abundant and has the longest lifespan in the atmosphere, contributing to the majority of the Earth's warming.
Greenhouse gases trap heat in the Earth's atmosphere, creating a "blanket" effect that prevents heat from escaping into space. This leads to an increase in the Earth's temperature, also known as global warming. The more greenhouse gases present in the atmosphere, the thicker the "blanket" becomes and the more heat is trapped, leading to further warming.
The main sources of CO2 emissions include burning fossil fuels for transportation, electricity, and industry, as well as deforestation and other land use changes. The burning of fossil fuels is the primary source, accounting for over 75% of global CO2 emissions.
Increased CO2 levels can have a range of consequences, including rising sea levels, more frequent and severe natural disasters, disruptions in ecosystems and agriculture, and negative impacts on human health. It can also lead to ocean acidification, which can have damaging effects on marine life and ecosystems.
