global warming could change the weather.


Scientists predict that during global warming, the area north of the northern hemisphere will heat up more than other regions on Earth. Consequently, the icebergs will melt and the mainland will be reduced. Will be less ice floating in the waters of the North. Areas that previously experienced light snow, probably will not experience it again. In the mountains in subtropical areas, snow-covered part will be less and will melt faster. Planting season will be longer in some areas. Temperatures in the winter and at night would tend to increase.
Warmer regions will become more humid as more water evaporates from the ocean. I think scientists have not really sure if the humidity is even warming will increase or decrease further. This is because water vapor is a greenhouse gas, so that its presence will increase the insulation effect on the atmosphere. However, more moisture will also form more clouds that reflect sunlight back into space, where it will reduce the heating process. High humidity will increase rainfall, on average, about one percent for each degree Fahrenheit warming. (Rainfall in the entire world has increased by 1 percent in the last hundred years). storms will become more frequent. In addition, the water will evaporate from the soil faster. As a result, some areas will become drier than before. Winds will blow harder and perhaps with a different pattern. Hurricane storm (hurricane) that obtain power from the evaporation of water, will become larger. Contrary to the warming that occurred, some very cold period will probably happen. Weather patterns become more unpredictable and extreme, maybe this will happen due to the impact of global warming having an effect on weather
