Some scientists predict that such warming will result from increasing amounts of carbon dioxide in the atmosphere.

I too have been skeptical of the notion that any significant warming of the earth will result from increases in certain trace gases in the atmosphere.

This suggested infrared radiation leakage was hypothesized to be a negative feedback in which an initial warming would result in an overall cooling of the surface.

Global warming may result in further rises in the future, which presents a risk to coastal cities as most would be flooded by only small rises.

Overall, global warming will result in increased world rainfall.

However global warming has resulted in raising sea levels, higher waves and more frequent extreme weather.

Initially, global warming will result in a lengthening of the annual growing season.

Although global warming will result in increased world rainfall, warmer temperatures also bring increased evaporation and increased drought frequency.

Scientists warn that global warming and climate change may result in more extensive droughts in coming years.

But they found that after the mid-1970's, when about half the century's warming took place, the warming resulted largely from the greenhouse gases.
