   Is This Proof Of Global Warming?
   
   There is so much debate over global warming but to me this seems like an alarming picture. Take a look and let me know your thoughts.

   No, this image doesn't prove anything. Two snapshots do not convey trajectory over time. And in some cases, people will use such snapshots as evidence against global warming. For example, if you take a summer 1980 photo compared to a winter 2012, it may not look like there is any difference at all. Of course, you have to compare winter to winter to have any meaning.
   
   Point is, that to really convey a useful measure of sea ice change, one must consider the change over time and the change in volume (not just the 2D extent). The attached image, for example, shows the change in ice volume over time (as anomaly).
   
   Also, the change in ice still doesn't by itself prove anything. It is one piece of a much larger and complex puzzle and needs to be considered within that context.
   
   And yes, according to scientists who study and understand that larger complex puzzle, global warming and climate change are occurring and are mostly a result of human activity.

      This is probably the best answer I've seen on a topic. Very well said!

   global warming happening because of many reasons. deforestation, rapid and unscientific industrialization, and many things. In fact Global warming is a real phenomenon. There are many proofs/pictures which giving messages about globalization. I think this picture is such a one. because which showing the changes over the Earth.

   Ice Age creatures did not have factories or SUVs. Although we can observe that there are "climate changes" going on, one must be careful to read what is behind the various groups and individuals who want to use it to control our lives. Al Gore made a fortune and denied Irena Sendler a Nobel Prize with a lot of false information. He had also positioned himself to make a fortune along with his Wall Street friends by brokering carbon credits. Thankfully, people caught-on.
   
   The key to environmental recovery is to help nature help itself. Re-forestation has a lot of power to restore air, wildlife and soil. Phyto-mediation is very promising in cleaning both land and water. Our cities have a lot of big and little spaces where more planting and more solar should be employed.
   
   Just don't be fooled. Anytime elites want us to make ourselves poor so they can get wealthy brokering our wealth away, chances are the money will only go to other elites, Wall Street, and Washington bureaucrats. Local governments should have those funds to help local sites and all should be held accountable. Meanwhile, we can all do our part.

   First of all, there is and will be no "proof" except in hindsight. Global warming and its cause due primarily to human activity is a probability, albeit a very high one, in the high 90s percentile. There may be "elites" who promote the idea and those who do not, but that has absolutely nothing to do with scientific consensus on this phenomenon. Also, don't be fooled by people who make the simplistic claim that the Earth's temperature has risen and fallen in past ages. While that is true, it has never, according to ice core data going back hundreds of thousands of years, risen so far in so short a time. Past temperature rises took 10s of thousands of years at minimum. The fact that the CO2 levels are now reaching 400 PPM in our atmosphere is also an event not seen in over 200,000 years and is strong evidence that human activity since the start of the Industrial Revolution is driving this.

   Global warming is a natural process. The ice caps change year by year and also throughout each year. There are no dates just the years on the two images and so they could be from different times of the year so this would not be able to be used as evidence.
