Question

which of the following perpetuate the global warming process, making it more and more intense as time passes?
correct answer(s)
increased temperatures cause polar melting and increase the water table.
increased temperatures lead to increased precipitation and flooding.
water vapor is the most potent greenhouse gas, and its concentration increases with temperature, up to the point of water saturation.
increased temperatures increase the decomposition of carbon in previously frozen permafrost, releasing co₂ and ch₄ into the atmosphere.
increased temperatures lead to the melting of methane clathrates, which releases methane (ch₄) into the atmosphere.

Explanation:

• Polar melting due to increased temperatures reduces Earth's albedo (reflectivity), making it absorb more heat. Higher water tables can also affect local and global climate patterns.
• Increased precipitation and flooding can disrupt ecosystems, change weather patterns, and potentially lead to more extreme weather events, all of which can influence the global warming process.
• Water vapor is a greenhouse gas. As temperatures rise (up to water saturation point), more water evaporates, increasing the greenhouse effect and further warming the planet.
• Decomposition of carbon in permafrost releases \(CO_2\) (a major greenhouse gas) and \(CH_4\) (a very potent greenhouse gas), enhancing the greenhouse effect.
• Melting of methane clathrates releases \(CH_4\) (a powerful greenhouse gas) into the atmosphere, which traps heat and contributes to more warming.

Answer:

All the given options (Increased temperatures cause polar melting and increase the water table; Increased temperatures lead to increased precipitation and flooding; Water vapor is the most potent greenhouse gas, and its concentration increases with temperature, up to the point of water saturation; Increased temperatures increase the decomposition of carbon in previously frozen permafrost, releasing \(CO_2\) and \(CH_4\) into the atmosphere; Increased temperatures lead to the melting of methane clathrates, which releases methane (\(CH_4\)) into the atmosphere) perpetuate the global warming process.
