No one really questions whether global warming is occurring.  The scientific facts are well accepted.  The Earth is warmer now than it has been at any time in recorded history.

What is very much a subject of debate is the extent to which the warming is a problem and the extent to which the warming is caused by human activity.

The planet's temperature has varied fairly widely over the course of geologic time.  That is why, for example, there were once, but no longer are, huge glaciers reaching down all the way into the continental US as there were in the latest ice age.  So swings in temperature may be natural.

The effects of warming are also uncertain.  Some places may actually be better off if warming occurs.  In addition, climate is simply too complicated to be able to predict with any certainty what impacts warming will have on any given area.

My personal opinion is that warming is caused by people and will be a problem.  However, that is not absolutely certain.

Actually, Earth has always gone through cycles of global warming and global cooling. However, the trend in the past 100 years or more is that carbon dioxide levels have been increasing and the climate has gotten warmer. However, one solution is reforestation due to the fact that plants absorb CO2 during photosynthetic activity. Another could include using mass transit and car-pooling, bicycles and walking. Since combustion of fossils fuels is the main culprit of production of greenhouse gases, maybe we need to focus on alternative energy sources like hydrogen fuel for the future.

Actually, I do think some people question global warming, and others just say that it is not caused by humans.  Most of the people who believe humans do not cause global warming do not want to reduce emissions because it makes products more expensive to create, or they lose money because they are in the business of fossil fuels.

I would have to agree that global warming is indeed a real occurrence in our world today. I think that trophyhunter has done an excellent job of explaining what can be done to help with the problem. The biggest problem is that there ere many things that have taken place that we can not go back an "undo" them.

Global Warming, or as we call it now, Climate Change, exists and its man made. Denying climate change has become somewhat of a trendy thing to do for politicians and the like. But those that refuse to accept it refuse to accept decades worth of scientific research that all come to the same conclusion. 97% of scientists came to this conclusion.

What recommendations are there to solve the problem of Global Warming?

The average temperature on Earth has increased by almost one degree since the mid-nineteenth century until today. Warming process is primarily due to emissions of greenhouse gases, especially carbon dioxide (CO2).
Greenhouse gases in the atmosphere have exceeded the quantity of the nineteenth century by 284 parts per million (ppm), amounting to 380 ppm today. The latest researches show that an additional increase in temperature, of one degree Celsius, could trigger dangerous climate changes.
