The Intergovernmental Panel on Climate Change, an international collaboration of scientists, puts together a report roughly every seven years to outline our current state of knowledge surrounding climate change. The most recent report (from 2015) shows that nearly 98% of climate scientists agree that modern-day climate change is a result of human activity

Although some people present this as a debate (or something that in uncertain), that is simply not the case. Please see the attached link for more information. I suggest you begin with the "Summary for Policymakers" PDF at the top of the page, which is written in the simplest language possible. I also suggest you visit Climate Central, which is a media organization run by current and former scientists that has the most up-to-date news on climate change.

It's important when using the term "global warming" to keep in mind the industrial processes that have increased the carbon dioxide level in the atmosphere as well as the natural processes of climate the Earth undergoes.  As everyone knows, weather is not stable, and we're discovering that weather patterns are not stable as well -- long before industrialization began, there have been major shifts in weather patterns that have been historically noted; scientists have gathered evidence from prehistory about the ever-changing climate of Earth.

It's agreed that Earth is now warming.  However, it's unclear that that is due entirely to industrialization.  If we hadn't had an Industrial Revolution 200 or so years ago, and not accumulated high levels of carbon dioxide in the air, would Earth be warming now anyway?  See link:

1. We are producing carbon dioxide faster than the earth can absorb it.

2. and 3. While no one can predict what will happen if the earth continues to get hotter, one can imagine. If the arctic caps melt more, there could be enormous flooding, which could completely destroy cities. If this takes place, there will be other consequences. For example, think of the economy.

4. Again no one knows, but see link for some guesses.

5. It probably started during the industrial age when people accelerated the consumption of natural resources and we have done a horrible thing by cutting down our forests!

6. and 7.  We all need to play a part to play. To support the whole Green movement is one way. Buy local and organic, for one thing.

1. Several factors play a role in producing global warming: the presence in the environment of increasing quantities of high carbon dioxide, methane and other gases, thinning of the ozone layer in the stratosphere.

2.Thinning of the ozone layer caused from the beginning, highly visible effects: increasing the number of people with severe burns after a moderate exposure to sunlight and dramatic increase in the number of people suffering from skin cancer.

3. Climate change is announced by special weather phenomena, which is manifested in recent years with increased amplitude and increased frequency. The newscasts are increasingly frequent reports about droughts and floods accompanied by landslides, hurricanes or tornadoes, blizzards and "carp stone cold" or heat "liquefies the asphalt. Scientists argue that responsible for the exacerbation of these extreme events is the phenomenon of global warming.

4.Climate models developed by experts in the field estimate that the global climate will warm by 1.1 to 6.4 ° C during the 21st century. Estimates vary because of the fact that it  can not be predicted evolution of gas emissions that cause greenhouse effect.Moreover, the tendency to continue heating the planet in the XXI century is revealed by many studies in the field. Very worrisome is that these climate scenarios  show that the polar areas will warm the most, which could have dramatic consequences.

5. Global warming begun around the sixties, after massive industrial development  and the increase of greenhouse gases amounts that are considered largely responsible for this phenomenon.

6.and 7. To avoid a bleak future of the planet, it should,by 2050, greenhouse gas emmisions to decrease twice at global level and four times for industrialized countries.
