EVERYDAY SCIENCE

Detailed explanation-1: -It works like this: As greenhouse gases like carbon dioxide and methane increase, Earth’s temperature rises in response. This increases evaporation from both water and land areas. Because warmer air holds more moisture, its concentration of water vapor increases.

Detailed explanation-2: -Today, the ocean has absorbed about 90 percent of the heat generated by rising emissions. As the excessive heat and energy warms the ocean, the change in temperature leads to unparalleled cascading effects, including ice-melting, sea-level rise, marine heatwaves, and ocean acidification.

Detailed explanation-3: -The higher the temperature, the more water vapor a volume of air is capable of holding. Therefore, any change in temperature alters the volume’s water vapor capacity. As air warms, its capacity for holding water vapor increases; as it cools, the capacity decreases.

Detailed explanation-4: -What they found: Surface warming is causing a faster increase in humidity, since warm air can hold more water vapor, and warming seas and land surfaces are giving up more water into the atmosphere through evaporation.

Detailed explanation-5: -First, as the oceans warm due to an increasing global temperature, seawater expands-taking up more space in the ocean basin and causing a rise in water level. The second mechanism is the melting of ice over land, which then adds water to the ocean.
