Question

what are the impact of greenhouse gases​

Answer 1

Green house effect is the gradual heating of Earth's atmosphere and surface, a process known as global warming. These greenhouse gases include water vapor, CO2, methane, nitrous oxide (N2O) and other gases, according to the Environmental Protection Agency (EPA).

Other impacts such as :-

Rise in global warming.

Increased carbon dioxide levels will affect biological systems.

Polar ice caps melting.

Increased probability and intensity of droughts and heat waves.

Warmer waters and more hurricanes.

Spread of disease.

Answer 2

Answer:

Explanation:

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere.

Radiatively active gases (i.e., greenhouse gases) in a planet's atmosphere radiate energy in all directions. Part of this radiation is directed towards the surface, warming it. The intensity of the downward radiation – that is, the strength of the greenhouse effect – will depend on the atmosphere's temperature and on the amount of greenhouse gases that the atmosphere contains.

Earth’s natural greenhouse effect is critical to supporting life, and initially was a precursor to life moving out of the ocean onto land. Human activities, however, mainly the burning of fossil fuels and clear cutting of forests, have accelerated the greenhouse effect and caused global warming.

The planet Venus experienced runaway greenhouse effect, resulting in an atmosphere which is 96% carbon dioxide, with surface atmospheric pressure roughly the same as found 900 m (3,000 ft) underwater on Earth. Venus may have had water oceans, but they would have boiled off as the mean surface temperature rose to 735 K (462 °C; 863 °F).

The term "greenhouse effect" continues to see use in scientific circles and the media despite being a slight misnomer, as an atmosphere reduces radiative heat loss[8] while a greenhouse blocks convective heat loss.The result, however, is an increase in temperature in both cases.
