Is carbon dioxide the main contributor to climate change?

 

If you hear about climate change, you will come across with some terms like "carbon footprint", which is the total greenhouse gas emissions by someone or something expressed as a carbon dioxide equivalent. But barely you will hear about water vapor, which is the main contributor to climate change. Water vapor comes from the oceans due to the temperature of the Earth's atmosphere.

So, why do we not hear much about water vapor? This is basically because if the Earth's atmosphere get hotter is due to carbon emissions, so if we reduce these emissions, the Earth's atmosphere will get colder preventing the oceans from evaporating at such high rates.

Methane plays an important role in climate change

  A great deal of methane is produced by cow's burps and feces. In addition to that, there is another contribution coming from wastes in landfills and rice cultivation. Since the major contributor to the production of methane are dairy farming activities many people are choosing to be vegetarian in order to reduce the methane production. Having said that, it's important to mention that methane is far more devastating than carbon dioxide on the climate. It's just because there is less methane than carbon dioxide that we are not usually hear about this. However, 15% of global warming is attributed to methane. So, if we want to combat global warming. We should also be concerned by methane.

Is the Green House Effect an appropriate name?

1.      Anyone who has visited a greenhouse knows that the temperature inside is higher than outside. And that's the reason why the cause of global warming has been defined as the greenhouse effect. However, this is just a metaphor; in fact, not a good one because while global warming is caused by some gases such as water vapor, carbon dioxide and methane, that absorve the radiation from the Earth that has previously come from the sun; greenhouses are hotter because the warm air cannot escape via convection. Due to this some scientists have introduced another term to explain global warming in simpler words: "the blanket effect". According to them the gases are a kind of blanket that prevents the gases from getting outside like when we are wrapped in a blanket that avoid us getting colder.
