What is the greenhouse effect, and is it affecting our climate?
Best answer:
Answer by charumathi j
it is the raise of carbon di oxide,chloro flouro carbon in earth…this can cause ozone hole enabling high radiations to fall on earth,gradually the temperature also increases…hence climatic variations happens..this in turn affects our ecological balance…

Some would have you believe this…and to be honest…they have demonstated this effect in a laboratory.
However, in real life……if this were happening….where is the heat waves ? We hear of the coldest days in many states…we hear of the longest snow fall in chicago, we hear of it snowing for the first time in decades in Las Vegas….so where are the cities that are over heated ? where’s the news of consistant unusual heat ?
All there have been in the past has been news scattered here and there about a “heat wave” but nothing unusual…nothing equivalent to it snowing in Las Vegas.
There is no real evidence that the greenhouse effect is happening in the real world and there’s even less evidence that even if it were happening that the world, in its complexity , isn’t dealing with it within its natural cycles to compensate for any abnormalities. Other than drought conditions….more people die of exposure and damage due to cold…not heat………….praportionally.
Basically what it is , is the trapping of heat in the confines of the earth atmosphere due to the supposed buildup of carbon.
I’d like to hear how the enviro whacko’s explain that if Carbon is so bad, then why is Al Gore (the modern day father of enviro whacko agendas) getting rich by simply trading carbon emmissions…rather than get rid of them ? If we did this trading BS back in the 70′s with pollution ……then we wouldn’t have the clean air and water we have today.
Lots of Co2 that is keeping in more sun heat than the earth needs.
Certain gases, called greenhouse gases (such as carbon dioxide, ozone, and water vapor) essentially trap energy that would otherwise escape to space, and act almost as a blanket keeping the earth warmer. Without the greenhouse effect, the temperature of the earth’s surface would actually be below freezing. Of course, an increase in the amount of these gases, such as the increase in carbon dioxide, would result in a further warming of the earth’s surface. This is what is currently changing our climate.
The greenhouse effect is is pretty complex overall. Basically it is when gases build up in the atmosphere and trap the suns rays inside. Normally radiation hits Earth and is reflected off the ice on the globe and some of it is absorded by land and water. Well the ice bounces the radiation up but the atmosdphere is thicker now because of the greenhouse effect so it sends the radiation back to Earth instead of letting it loose. Over time this causes a build up of radiation on Earth. (This radiation is UV rays and Gamma Rays A.K.A. Light and Heat Energy) Now as the water and ground heat up it melts the ice and glaciers…Which make more water and less ice to reflect radiation. The more water the faster the ice melts thus once we start the process it is hard to stop. Now as the water rises this causes a shift in climate. Come places that were warm are going to get cold. Some places that were cold are going to get warm. The oceans will rise and consume all the coasts of the major continents. Glaciers are forming in California on the mountains, but they are also melting in the arctic circle. Weather will also change due to the different atmosphere.
Greenhouses hold humidity and by combining it with steady temperature help plants grow in a healthy environment. Think of the earth as a very large greenhouse. The earth produces heat and humidity in various levels which means some places are too dry or wet or not warm or visa versa for habitation to flourish. We cannot control nature. Try to stop a volcano from erupting.
it affects our climate quite a bit.
without any greenhouse effect, most — maybe all — the planet would be below freezing.
the question you mean to ask is, “is our climate changing, and is that change related to our activities?”
and the answer is, “it’s getting warmer, mostly because of the CO2 we’ve put into the atmosphere.”
here’s what the science says — not what i or some troll claims.
NAS, NOAA, NSF, NASA, EPA, MIT, UCLA all agree. AGW (Anthropogenic Global Warming) is a serious problem.

The greenhouse effect refers to the change in the thermal equilibrium temperature of a planet or moon by the presence of an atmosphere containing gas that absorbs and emits infrared radiation.[1] Greenhouse gases, which include water vapor, carbon dioxide and methane, warm the atmosphere by efficiently absorbing thermal infrared radiation emitted by the Earth’s surface, by the atmosphere itself, and by clouds. As a result of its warmth, the atmosphere also radiates thermal infrared in all directions, including downward to the Earth’s surface. Thus, greenhouse gases trap heat within the surface-troposphere system.
If the greenhouse effect increases, it will affect the climate changes. The weather in certain place will change from hot to cold, from cold to hot temperature.
A. Solar heat reaches Earth in the form of visible and UV light. Some of this light is reflected back into space by clouds and light-scattering particles before it reaches Earth’s surface. Most of the light does reach Earth’s surface, providing warmth for sunbathers and energy for photosynthesis in plants.
Once this energy warms the planet, it is then reflected off of Earth and back towards space in the form of longwave energy, or infrared light. Some of this infrared energy escapes into outer space, and some will be absorbed by molecules in the atmosphere. Most molecules in the atmosphere, such as nitrogen and oxygen, can not absorb this infrared energy. Greenhouse gases (CO2, H2O, and CH4) are “tuned” to absorb energy at infrared wavelengths. Absorbing energy “excites” these greenhouse molecules.
The excited molecule can either re-emit the infrared wavelength. Or, the energy is released from “excited” greenhouse molecules through collisions with other molecules. Such collisions will transform the energy to heat; some of the heat is lost to space, some is directed downwards and warms earth’s surface even more.
B. Earth has a natural greenhouse gas effect. It is true that if the atmosphere completely lacked greenhouse gases, then the global temperate would then be about 30°C (55° Fahrenheit) cooler. Water would be locked away as ice, and life would probably not be possible.
Most molecules in the atmosphere, ~99% of them, are opaque to both incoming solar light and outgoing infrared radiation. The concentration of CO2 has increased by 35% since industrialization, from 280ppm to 285ppm. The concentration of CO2 was steady at 280ppm for 10,000 years, since the ice age ended. Man’s activities are responsible for most, if not all of this increase.
The greenhouse effect is why we have a livable climate. Otherwise the earth would be just like the moon; frigid on the dark side and boiling on the light side. Global warming caused by humans is the theory that we are adding more of the green house gasses to the atmosphere thus making the planet warmer. Kinda like adding another blanket to your bed at night.
rising concentrations of greenhouse gases produce an increase in the average surface temperature of the Earth over time. Rising temperatures may, in turn, produce changes in precipitation patterns, storm severity, and sea level commonly referred to as “climate change.”
Assessments by the Intergovernmental Panel on Climate Change (IPCC) suggest that the Earth’s climate has warmed between 0.6 and 0.9 degrees Celsius over the past century and that human activity affecting the atmosphere is “very likely” an important driving factor.1 The IPCC’s Fourth Assessment Report (Summary for Policymakers) states, “Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.” It goes on to state, “The observed widespread warming of the atmosphere and ocean, together with ice mass loss, support the conclusion that it is extremely unlikely that global climate change of the past 50 years can be explained without external forcing, and very likely that it is not due to known natural causes alone.”
