What is the greenhouse efect

Since the dawn of the Industrial Revolution in the early s, the burning of fossil fuels like coal, oil and gasoline have greatly increased the concentration of greenhouse gases in the atmosphere, especially CO2, National Oceanic and Atmospheric Administration NOAA.

Harmful effects of greenhouse effect

Burning fossil fuels like coal and oil puts more carbon dioxide into our atmosphere. Its glass walls trap the Sun's heat, which keeps plants inside the greenhouse warm — even on cold nights. This is called ocean acidification. How Does It Work? Greenhouses are used to grow plants, such as tomatoes and tropical flowers. Currently, some scientists are investigating how to re-engineer the atmosphere to reverse global warming. Created and produced by QA International. A main cause of coral bleaching is warming oceans. Enhanced greenhouse effect The problem we now face is that human activities — particularly burning fossil fuels coal, oil and natural gas , agriculture and land clearing — are increasing the concentrations of greenhouse gases. The "greenhouse effect" is not the same as global warming. The greenhouse effect is somewhat similar to the process that goes on in a real greenhouse.

To understand global warming, it's first necessary to become familiar with the greenhouse effect, though. The ocean also absorbs a lot of excess carbon dioxide in the air.

As they heat up, the oceans, land and atmosphere release heat in the form of IR thermal radiation, which passes out of the atmosphere and into space. Despite its name, the greenhouse effect is different from the warming in a greenhouse, where panes of glass transmit visible sunlight but hold heat inside the building by trapping warmed air.

But some of the heat is trapped by the greenhouse gases in the atmosphere.

greenhouse effect wikipedia

The greenhouse gases then emit their radiation also longwavewhich will often keep being absorbed and emitted by various surfaces, even other greenhouse gases, until it eventually leaves the atmosphere.

Greenhouse gases also make their way to the atmosphere from other sources.

causes of greenhouse effect

The presence of "greenhouse" gases in the atmosphere, however, changes the radiation balance. A greenhouse stays warm inside, even during the winter.

What is the greenhouse efect

At nighttime, it's colder outside, but the greenhouse stays pretty warm inside. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.

Greenhouse effect diagram

The Earth and the Sun work in a similar fashion on a much more massive scale and a different physical process. Mitigate the impact of climate change by aggressively enacting policies that actually reduce the concentration of CO2 in the atmosphere. Their effects, together with those of other anthropogenic drivers, have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the midth century". Voyages What is the greenhouse effect? Greenhouse effect. Click here to learn how you can be part of this historic event on November 20— It has a much weaker magnetic field meaning less protection from solar radiation and heating effects [41] Its very dense atmosphere consists mainly of carbon dioxide. Greenhouse effect Step 1: Solar radiation reaches the Earth's atmosphere - some of this is reflected back into space.
