Effects Of Global Warming On Weather

Effect Of Global Warming on Weather:  The various effects are:

1. Extreme Weather: Storm strength leading to extreme weather is increasing, such as the power dissipation index of hurricane intensity. Severe weather and moderate rainfall are also increasing. Increases in temperature are expected to produce more intense convection over land and a higher frequency of the most severe storms

2. Increased Evaporation: As the climate grows warmer and the causes of global dimming are reduced, evaporation will increase due to warmer oceans. Because the world is a closed system, this will cause heavier rainfall, with more erosion. This erosion, in turn, can lead to desertification in vulnerable tropical areas (especially in Africa due to deforestation.

3. Glacier Retreat and Disappearance: The loss of glaciers not only directly causes landslides, flash floods and glacial lake overflow, but also increases annual variation in water flows in rivers. Glacier runoff declines in summers as glaciers decrease in size; this decline is already observable in several regions. Glaciers retain water on mountains in high precipitation years, since the snow cover accumulating on glaciers protects the ice from melting. In warmer and drier years, glaciers offset the lower precipitation amounts with a higher melt water input,

4. Sea Level Rise: With increasing average global temperature, the water in the oceans expands in volume, and additional water enters them, which had previously been locked up on land in glaciers. The IPCC predicts that sea levels could rise by as much as 59 cm this century. The geological record suggests that ice at the poles does not melt in a gradual and linear fashion, but flips suddenly from one state to another. When temperatures increased to 2-3 degrees above today's level 3.5 million years ago, sea levels rose not by 59 centimetres but by 25 metres. The ice responded immediately to changes in temperature.

5. Acidification: The world's oceans soak up much of the carbon dioxide produced by living organisms, cither as dissolved gas, or in the skeletons of tỉny marine creatures that fall to the bottom to become chalk or limestone.Oceans currently absorb about one tone of Carbon Dioxide per person per year. It is estimated that the oceans have absorbed around half of all Carbon Dioxide generated by human activities since 1800. However, in water, carbon dioxide becomes a weak carbonic acid, and the increase in the greenhouse gas since the industrial revolution has already lowered the average pH.
