Does the Greenhouse effect actually raise the temperature in our atmosphere and cause our ice caps to melt ?

and if they melt, cause our sea levels to rise ?

in a hundred years time I wonder what it will be like,  how much land will be arid and fertile and how much will have become submerged under water thanks to global warming and the greenhouse effect.

or is this all scaremongering nonsense ?  are the ice caps really melting at all ? who has seen them melting ?

    depends on what the college grant asked the professor create  prophesy of 

    remembering a new grant budget is needed every year 

    ---------------

    this of course has become a faith not science

    Estimate are for a 1 to 1.5 metre (3.3 to 5 foot) rise in sea level across the world by the end of this century. That will be problematical for all those great cities which are very near sea level. London, New York, Melbourne,  Amsterdam, Copenhagen and many others.

    To you're last ..., I've actually seen them melting. So yes, they are in fact melting. As the Ice melts sea levels will rise. Ironically, all of the continents are also experiencing desertification. This generally begins at the interior of the land mass and spreads outwards. So in about 20 years N. America will be a large dish of sand, rimmed with a bit of green, floating in an ocean of diluted brine.

    Yes. It's a scientific fact.

    Arctic sea ice is definitely melting as temperatures rise. Arctic ice is at its greatest extent in March and its lowest extent in September. If you look at September extent over the years you find we are losing more than 10% per decade relative to the average between 1979 and 2010.

    The Antarctic is a different story. If anything, the data shows increases in ice. How can a warming world produce more ice? Because Antarctica is a continent and ice is formed by snow. Warmer temperatures produce more water vapour and hence more precipitation. However, some parts are warming and some parts of that huge continent are cooling. 

    In terms of sea levels then, the Arctic melt has virtually no impact because the ice is formed by freezing sea water. No additional water is being added. If ice on Antarctica (as opposed to sea ice) melts, that will raise sea levels. But the one thing you've ignored are glaciers across the Northern hemisphere. The overwhelming majority of these are melting and adding to sea levels.

    Currently, sea levels are rising by a little over 3 mm per year or more than an inch a decade. About half of that is thermal expansion of the oceans as they warm. The rest is ice melting and water running off land. There is already some evidence that this cold freshwater runoff is impacting the position of ocean currents and gyres around Greenland.

    if you doubt whether this phenomenon is true or fake ,you'd better take ships to witness first hand the iceberg ,ice caps or if you find that the iceberg still drift and is as big as it was ,then you can tell whether the global warming is fake ,greenhouse effect brought by the burning of fossile fuel is recognizable fact

    The world has been through it all at least several times.  A large percentage of global warming is due to the world's ever changing tilt on its axis and ice ages and periods of excessive heat come and go.  This time the world has other things making the earth's heating worse.  Man now has become a blight on the surface of the planet spewing huge amounts of heat from cars, factories and other sources, and also man is belching out huge amounts of carbon dioxide and other gases that help trap solar heat onto the planet, then we have also cut down huge swathes of forest and Jungle that help absorb this carbon dioxide releasing the oxygen content back into the atmosphere.  Excess carbon dioxide causes the oceans to acidify to the point most sea life will die, sea levels rise,  Low lying land will and whole countries will disappear submerging a lot of man's cities and farming land, causing man to clear a lot more of the jungle and forests which will cause the air to contain carbon dioxide in amounts that will start to destroy some life on earth and make man crowd into much smaller areas with many unlikely able to feed themselves.  Likely wars will start over food shortages and people will no longer have large homes as land will be at such a premium no normal person will be able to afford it.

      Apparently run away global warming and acidification of the oceans in the past have taken several millions of years to get back to the sort of planet we have now.  They say it will be another 80,000 years before the next ice age and oceans begin to be locked up in polar ice again and levels drop, but this does not take into account how much heating man has added to the earth.  Likely there will be a lot less people here to see it than there are now.

      I was born on a farm 60 years ago and have seen the weather changing.  Winters were a lot wetter and I remember fields flooding after large rains and my father trying to dig drains to drain the water away.  The river near our house flooded at least 3 times a year, but now the fields no longer flood and we may see a flooding of the river every 2 or 3 years.  City people see very little except complain if its raining forgetting the rain is very important for growing their food and supplying the needs of the city water supply.  In the cities people see little of the problems of global warming but out here in the rural areas it is very obvious and already causing problems.

    The CO2 greenhouse effect of the Earth’s atmosphere is a pure fiction of people who like to use large computers, without physical bases. 

    The real mechanisms that control the temperature of the planet, are the Sun’s energy and the air pressure of the atmosphere. The so-called “greenhouse effect” is actually a function of the activity on our host star plus the atmospheric pressure resulting from gravity and the mass of the atmosphere, rather than the atmospheric concentrations of greenhouse gases such as CO2 and water vapor.
