Positive feed backs. A warming planet causes changes in various aspects of the planet, and some of these changes may cause further changes, including more heating, or even cooling.
One example of this is water vapor. As the planet warms, more water can be evaporated and held in the atmosphere. Since water vapor is a potent greenhouse gas, this extra water vapor in the atmosphere creates even more warming. And there you go, warming causing warming.
Other positive feed backs include the ice albedo effect and the melting of methane permafrost.
Negative feed backs would be an increase in clouds from evaporation. Plant life able to survive in areas previously unable to support life in another example of negative feedback.
The ice mass in the Arctic is generally decreasing, although there is a small short-term increase in sea ice, and with it comes albedo issues.
Another potential for global warming to cause further global warming is the the melting of the Siberian tundra. Considerable organic carbon is held in the soil, frozen so that it can not rot and convert into carbon dioxide. Should this melt, scientists say that further global warming would become unstoppable.
Yes. There are things happening in global warming that cause positive feedback. For example, Arctic ice is white and shiny, so it reflects a lot of the sun's rays. This is called albedo. As the atmosphere warms, the Arctic ice melts, exposing the dark sea below. The dark sea doesn't reflect the sun's radiation as well as the ice did, so it gets warmer.
Because the sea is warmer, it melts more of the ice. Because the ice has gone, the sea gets warmer.
This is called positive feedback, and it is an example of how global warming can cause more warming.

Does global warming cause avalanches?
Global warming can increase the risk of avalanches through rising temperatures that lead to snowmelt and unstable snowpacks. This can result in more frequent and larger avalanches as the snow becomes more prone to sliding.
Is global warming the main cause of the thinning of the ozone layer?
Global warming is a cause of the ozone depletion. However it is not the main cause of it.
What is the Global Warming Potential for ozone?
Ozone depletion can cause global warming. It is due to the plankton death.
How do greenhouse gasses impact the ozone layer?
Greenhouse gases cause global warming on earth. This global warming can cause ozone depletion.
Who are the global warming skeptics?
Global warming skeptics do not believe the geoscientists, engineers and meteorologists round the world. The skeptic individuals believe that nature is the primary cause of global warming and/or that future global warming will not be a very serious problem.
How does global warming cause more heart attacks?
It doesn't!
Does global warming cause avalanches?
Global warming can increase the risk of avalanches through rising temperatures that lead to snowmelt and unstable snowpacks. This can result in more frequent and larger avalanches as the snow becomes more prone to sliding.
Is ozone depletion the cause why there is global warming?
Yes, it is. It is responsible for global warming.
Is global warming the main cause of the thinning of the ozone layer?
Global warming is a cause of the ozone depletion. However it is not the main cause of it.
What global warming may cause the water cycle to?
become more extrem
Why earth have a global warming?
There is no such thing as "a global warming" global warming only happens to earth because human and our unruly decrease in the earths resources. HUMANS cause global warming.
Does the earth's crust cause global warming?
No. While events on the earths crust can cause global warming, the crust itself does not.
Does farming cause global warming?
Farming contributes to global warming for several reasons, but global warming does not cause farming. Global warming causes difficulties for farmers, because it increases instability in the weather, meaning that weather is less predictable and there are more floods, droughts, and other weather extremes.
Does fishing cause global warming?
No.
Is the main cause of the thinning of the ozone layer global warming?
The main cause of thinning is CFC's. Global warming also affects it.
What is the name that gives gases that trap heat and cause global warming?
Greenhouse gasses are the cause of Global Warming.
How do polar bears cause global warming?
Polar bears do not cause global warming. In fact, polar bears are affected by global warming due to the shrinking of their sea ice habitat. The loss of sea ice reduces their hunting grounds and threatens their survival.
