Causes and Effects of Climate Change | National Geographic



human activities from pollution to overpopulation are driving up the earth's temperature and fundamentally changing the world around us the main cause is a phenomenon known as the greenhouse effect gases in the atmosphere such as water vapor carbon dioxide methane nitrous oxide and chlorofluorocarbons let the sun's light in but keep some of the heat from escaping like the glass walls of a greenhouse the more greenhouse gases in the atmosphere the more heat gets trapped strengthening the greenhouse effect and increasing the earth's temperature human activities like the burning of fossil fuels have increased the amount of co2 in the atmosphere by more than a third since the Industrial Revolution the rapid increase in greenhouse gases in the atmosphere has warmed the planet at an alarming rate while Earth's climate has fluctuated in the past atmospheric carbon dioxide hasn't reached today's levels in hundreds of thousands of years climate change has consequences for our oceans our weather our food sources and our health ice sheets such as Greenland and Antarctica are melting the extra water that was once held in glaciers causes sea levels to rise and spills out of the oceans flooding coastal regions warmer temperatures also make weather more extreme this means not only more intense major storms floods and heavy snowfall but also longer and more frequent droughts these changes in weather pose challenges growing crops becomes more difficult the areas where plants and animals can live shift and water supplies are diminished in addition to creating new agricultural challenges climate change can directly affect people's physical health in urban areas the warmer atmosphere creates an environment that traps and increases the amount of smog this is because smog contains ozone particles which increase rapidly at higher temperatures exposure to higher levels of smog can cause health problems such as asthma heart disease and lung cancer while the rapid rate of climate change is caused by humans humans are also the ones who can combat it if we work to replace fossil fuels with renewable energy sources like solar and wind which don't produce greenhouse gas emissions we might still be able to prevent some of the worst effects of climate change you

  1. The only practical, easy and best solution is planting trees on a regular basis. Practically, u can't shut down the usage of vehicles, u can just control it's usage. And when it comes to aeroplanes, u can't control their usage as, if u need to take very long routes, practically the best option is aeroplane only..No one will be willing to take car or train and travel for long hours if u had money or if u had to switch nations.. Here's a point to note.. Pollution can be called pollution ONLY IF THE LEVEL OF EMISSIONS "EXCEED" A LIMIT.. So the negative effect of excess CO2 emission can be compensated only by planting trees "regularly", which is not a difficult task.. Co2 Gas emission is not the real problem, only it's "amount" is the problem

  2. I remember the cover story of the November 1976 issue of National Geographic. It told of the coming Ice Age. The story was about the nearly 100 years of falling global temperatures and how the rate of the fall was increasing. A graduate student told me a few years ago that that Earth is the hottest it has been in 396 years! I replied great! That means the Earth is now cooler than it was the year before the Mayflower landed with the Pilgrims in 1620. She said, it sounds crazy when I say it that way. But she did agree we both stated the same fact.

  3. To save our lifeworld on this planet, being in this 'house on fire', we have first to extinguish the major cause of conflagration and the fire accelerant, which is nothing else than our monetary wold system which we have to extinguish replacing it fully and completely with the global digital networkings..!

    This world can only be saved and transformed In the necessary speed and in that scale intodrucing the, in history books subsequently really described as that, 'digital era' by replacing fully and completely the 'monetary era' with it!
    or
    This crisis can only be solved replacing, overcoming and eliminating the 'monetary era' with the, in history books subsequently really described as that, 'digital era'!

    The world has to hold its breath, to escape ahead and to redefine its civilization!

    The influences and effects of monetary systems can not be changed simply by trying to change the effects or just by changing them..

    "You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete." Buckminster Fuller

    For this great project of a currecy&tradeFree-OneWorldSociety, to pull an 'emergency brake, to do this radical change of course the world has to grow together, has to become one!

    For Banners:
    System change, not climate change! (that's the known one)

    Save this Planet! Replace the monetary world system fully and completely with the digital networkings in global cooperation!

    Replace the monetary world system | Shut down the monetary world system
    (fully and completely)
    with the digital world system! | with the help of the digital networkings!
    (Which only allows the radical change of course!)

  4. Hopefully some greenhouse effects will help to slow down the beginning of the new ice age by 2050. THAT is the real challenge of our time, to thrive during the modern solar minimum that is probably the beginning of the next ice age. The whole warming hysteria is a waste of time with what humanity has to endure once GLOBAL COOLING evolves more rapidly.

  5. Let’s be honest, climate change is incredibly easy to prevent. We just need to use electric cars, farm less, and use up less resources. Why hasn’t it been stopped yet? Money. The people controlling our society are more concerned about the money they make and the power they have over the decline of our earth. Global warming has been an issue as long as I can remember so why is it still a problem? Why is the government, who have the intelligence to create nuclear weaponry and who knows what, not doing anything about this. In 80 years the sea levels will be so high that the majority of our countries will become Atlantis and well all be gone. Will wealth and power be important then?

  6. global warming and climate change are the biggest profit scams ever. Do you really believe they would build more houses and give out long term loans if all this was real. Not on you life. It's all a government scam to control everything. The world has always Varied itself and repaired its problems. It doesn't need us interferer. Human interference will cause the problems causing the death of trees and animals and all plant life. You interfere with the biosystem that works you create chaos. Stop messing and leave the planet to heal it's own problems. mess with the co'2 balance and you'll destroy everything. It common sense. The Governments need to stop lying to the people .

  7. Greenhouse gases and the greenhouse effect appear to have very little impact on the Earth's surface temperature.
    The assertion that the Earth would be 33°K colder without Greenhouse Gases by IPCC reports seems to ignore atmospheric autocompression which accounts for nearly all of the 33°K warming. This phenomenon explains the temperature of planets in the solar system (the ones with enough atmospheric pressure), including Venus where the temperature has been reported to be caused by a runaway greenhouse effect by many news organizations.

    The greenhouse effect exists, but it has a very minor impact on surface temperature. Much smaller than what the IPCC reports claim. Temperature forcing by doubling CO2 concentrations is much lower than the range of 3-4.5°K.

  8. pure propaganda. Why isn't anyone selling land in antarctica? It would make sense. Average mean temps are way down from 1936.

  9. Matthew 16 : 2 " When evening comes, you say, It will be fine weather, because the sky is red and early in the morning you say, It will be stormy today, because the sky is red and threatening."

  10. John 3 : 8 "The wind blows where it will and you hear the sound of it, but you do not know whence it comes and whither it goes."

  11. Humans are the most lovable animals I know.

    They love in many ways, but love for money shouldn't be one of those.

  12. We can not fix what we never made.. .
    The abundance of ones heart we will say and do… I hear what we say but see what we do…. the heart will never change.

  13. It's sad, I don't wanna die, I'm 13 and I still have alot of time to spend on this planet, seeing beautiful places be destroyed by this act really is heartbreaking and it makes me question myself: Is this what world leaders are doing? Having political discussions when 7 billion + lives are on the line? Disgraceful. I may be someone who might not be powerful but every person's opinion matters.

  14. Hunans are responcible fo 3% of Global Warming. The REAL reason for ALL of the planets warming in our solor system is because of planet X , which is our 2nd Sun !! Go on you tube and look it up.! We have two suns that can seen next to our sun every day in all countries and this Planet X has melted the ice caps on all the planets so think why did the ice cap melt on Mars and our own Moon??? There are no cars on the Moon or Mars. Global warming is because of this new sun and the Evil ones at the U.N. are only trying to make money off this Global warming B.S. To see this sun you must have ultra violet lens which your smart phone has. It sits next to our sun.
