Natural forces play no significant role in the current global warming.
The three most prominent natural factors are solar output, volcanic eruptions and out gassing, and vegetation.
For the past thirty years solar output has slightly declined, but not enough to detect any measurable climate effect. The particulate spewed by volcanoes tends to temporarily lower earth's albedo, reflecting more sunlight, and the hydrogen sulfide gas vented also lowers the temperature. CO2 emitted by volcanoes will, over extended periods of time, counteract this. Currently humans release more than 100 times as much CO2 as all earth's volcanoes combined.
Vegetation can sequester carbon, which is how the vast deposits of coal and oil formed, hundreds of millions of years ago. Fifty million years ago a plant called Azolla, which grew in warm Arctic regions pulled about 40% of the CO2 out of the atmosphere, causing earth's temperature to fall over a span of just a few million years.
None of these natural forces, of course, play a significant role in the current global warming trend, which is primarily driven by anthropogenic (human caused) oxidation of fossil carbon.

Answer:
No scientist would disagree that without natural global warming we would be unable to exist on this planet. The past 11,000 years have seen a fairly steady warming trend totaling about 11 degrees C. Approximately 10 degrees of this warming has occurred before man started burning coal. The past 150 years has seen another degree of warming. Science experts all agree that a portion of this degree of warming is also natural. Many science experts, including many climate experts do believe that man is responsible for a portion of this one degree of additional warming. Some even are willing to say that man may be responsible for most of this one degree of warming. The bottom line though is that the overall warming trend of the planet would be impossible without natural forces such as the sun. Nature is the dominant factor here in every conceivable measurement, including emission of green house gases. Nature produces 99.7% while man produces less then 0.3%. All warming is due to our very naturally occurring sun. Without nature, there would be zero warming.
Global warming is not considered a natural disaster itself, but it can contribute to natural disasters such as hurricanes, wildfires, and droughts.

False. Global warming is primarily caused by human activities, such as burning fossil fuels and deforestation, which release greenhouse gases into the atmosphere and trap heat. Natural factors can also contribute to climate change, but the current warming trend is largely driven by human activities.
The current trend of Earth warming is primarily attributed to human activities, such as the burning of fossil fuels and deforestation, leading to an increase in greenhouse gases in the atmosphere. This has resulted in rising global temperatures, melting ice caps, and more frequent extreme weather events. It is a pressing issue that requires urgent global action to mitigate its impacts.
Global warming is not natural, it is caused by people. Since there aren't people on Neptune, it cannot have global warming.

The idea that Global Warming is a natural cycle is well understood from paleo.

The current evidence seems to support that the effects of the industrial revolution have caused the natural process to speed up dramatically. There is no way to stop global warming, but we can find ways to slow its current process.

Global warming
the earth goes through natural cycles of heating and cooling (ice-age and warming.) the thing is that natural cycles take centuries to millennium while the current warming phase is happening over decades- hence the name of global warming.
