2. Global Warming Without this greenhouse effect, the average surface temperature would be 255 degrees kelvin (-18 degrees Celsius or 0 degrees Fahrenheit); a temperature so low that all water on Earth would freeze, the oceans would turn into ice and life, as we know it, would not exist.

Greenhouse gas Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F). In the Solar System, the atmospheres of Venus, Mars and Titan also contain gases that cause a greenhouse effect.

Carbon dioxide in Earth's atmosphere Without the greenhouse effect, the Earth's temperature would be about −18 °C (-0.4 °F) compared to Earth's actual surface temperature of approximately 14 °C (57.2 °F). Carbon dioxide is believed to have played an important effect in regulating Earth's temperature throughout its 4.7 billion year history. Early in the Earth's life, scientists have found evidence of liquid water indicating a warm world even though the Sun's output is believed to have only been 70% of what it is today.

Impacts of a 4Â°C global warming The largest warming will occur over land and range from 4°C to 10°C. Increases of 6°C or more in average monthly summer temperatures would be expected in large regions of the world, including the Mediterranean, North Africa, the Middle East.

- Although the actual atmospheric lapse rate varies, under normal atmospheric conditions the average atmospheric lapse rate results in a temperature decrease of 6.4 °C/km (3.5 °F or 1.95 °C/1,000 ft) of altitude above ground level. The measurable lapse rate is affected by the moisture content of the air (humidity).he decrease of an atmospheric variable with height, the variable being temperature unless otherwise specified. In the lower regions of the atmosphere (up to altitudes of approximately 12,000 metres (39,000 ft), temperature decreases with altitude at a fairly uniform rate.

Global warming The global average (land and ocean) surface temperature shows a warming of 0.85 [0.65 to 1.06] °C in the period 1880 to 2012, based on multiple independently produced datasets. Earth's average surface temperature rose by 7002273890000000000♠0.74±0.18 °C over the period 1906–2005.limate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to 1.7 °C (0.5 to 3.1 °F) for their lowest emissions scenario using stringent mitigation and 2.6 to 4.8 °C (4.7 to 8.6 °F) for their highest.

- Without the atmosphere, the temperature on Earth would be more like the Moon, which rises to 116° C in the day, and then dips down to -173° C at night.he reason the average temperature on Earth is so high is because of the atmosphere. This acts like a blanket, trapping infrared radiation close to the planet and warming it up.

Greenhouse gas A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.Without greenhouse gases, the average temperature of Earth's surface would be about 15 °C (27 °F) colder than the present average of 14 °C (57 °F). greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range.

Global Climate Change: Evidence and Causes The Earth has a natural greenhouse effect where certain gases (known as greenhouse gases) in the atmosphere allow the sunlight to enter but absorb the heat radiation.Because these gases absorb the heat, they keep the average surface temperature on Earth around 14°C.ince the industrial revolution, human activity has increased the amount of greenhouse gases in the atmosphere (shown in the graph to the right). The increased amount of gases which absorb heat, has directly lead to more heat being retained in the atmosphere and thus an increase in global average surface temperatures.

- Venus on the other hand with it's much thicker atmosphere holds all the heat it gets. The heat the atmosphere traps is called the greenhouse effect. If Venus did not have an atmosphere the surface would be -128 degrees Fahrenheit much colder than 333 degrees Fahrenheit, the average temperature of Mercury.

- To many people, the term greenhouse effect conjures up dire images of Earth's future. Yet without it, Earth would be a frigid planet, with average temperature around zero degrees Fahrenheit instead of the 60 degrees it is today.

The Greenhouse Effect The Greenhouse Effect. Energy from the Sun that makes its way to Earth can have trouble finding its way back out to space. The greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases. Without the greenhouse effect, Earth’s temperature would be below freezing. It is, in part, a natural process. However, Earth’s greenhouse effect is getting stronger as we add greenhouse gases to the atmosphere. That’s is warming the climate of our planet.

Greenhouse effect 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 in the absence of its atmosphere.If a planet's atmosphere contains radiatively active gases (i.e., greenhouse gases) the atmosphere radiates energy in all directions.he 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 in the absence of its atmosphere.

Taking the Earthâs Temperature Although the results for the Earth’s temperature are usually given as anomalies, climate scientists have used the measured temperature data to calculate average temperatures. NOAA’s result for the 20th century average land-ocean Earth surface temperature is 13.9 °C. The 2011 NOAA surface temperature anomaly of 0.51 °C, gives an average Earth temperature of 14.4 °C for 2011. To find out more about how the Earth is warmed and the greenhouse gases that are responsible, see How Atmospheric Warming Works and Greenhouse Gases.

The Atmosphere of a Habitable Planet Yet too much carbon is also disastrous to life, so we should be appreciative that the Earth seems to have just about the right amount. Venus has about 100 times as much carbon and suffers from the runaway greenhouse effect that has produced a surface temperature of about 750 K compared to about 300K for the Earth.

Global warming and climate change Global warming is caused by a phenomenon known as the greenhouse effect. A greenhouse (or glasshouse) is good for growing things because it traps heat inside and stays hotter than the atmosphere around it.t's not really warming up noticeably—at least not in the short term. In fact, since 1900, the whole planet has warmed up only by around 0.8 degrees Celsius. By the end of the 21st century, however, global warming is likely to cause an increase in Earth's temperature of around 2–5 degrees Celsius.

- A drop of as little as 0.01 in Earth’s albedo would have a major warming influence on climate—roughly equal to the effect of doubling the amount of carbon dioxide in the atmosphere, which would cause Earth to retain an additional 3.4 watts of energy for every square meter of surface area.

The Earth System Without these gases, and the natural greenhouse effect, the average temperature of the Earth would be approximately -18°C (0°F) instead of its current 14°C (57°F) (see NOAA). Earth is one of the few planets in the solar system which has an atmosphere.

CONTENTS Venus has the hottest surface temperature (+864° F). Its very thick carbon dioxide atmosphere and sulfuric acid clouds act as a heat trap. This is called the greenhouse effect. Neptune, because of its distance from the sun, would possess the coldest atmospheric temperatures (-364° F).

Extraterrestrial atmosphere The air pressure at Venus' surface is about 92 times that of the Earth. The enormous amount of CO 2 in the atmosphere creates a strong greenhouse effect, raising the surface temperature to around 470 °C, hotter than that of any other planet in the Solar System.

- By contrast, without a greenhouse effect, the Earth would look like the lower diagram. The apparent temperature surface that we would see from space is located well above the real surface of the Earth where we live. This apparent temperature surface is about 5000 meters up (17,000 feet) within the atmosphere.
