what r the harmful effect of global warming ?
Harmful effects of global warming:
- Warmer waters and more hurricanes:As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes
- Increased probability and intensity of droughts and heat waves:Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves.
- Polar ice caps melting:The ice caps melting is a four-pronged danger.It will raise sea levels. There are 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today the seas would rise about 230 feet. Luckily, that’s not going to happen all in one go! But sea levels will rise.
- More floods:Flooding represents one of the most dangerous hazards to human settlements and is one of the most potentially momentous impacts of global warming. As the climate changes, a warming of the seas creates ‘thermal expansion’. This is where warm water begins to take up more space than cool water, making the sea’s surface level increase.
- Desertification:An increase in evapo-transpiration and the accompanying decrease in rainfall mean that already semi-arid and sub-humid areas found across the world would face a future barrenness that is almost irreversible.
Disadvantages of Global Warming
Ocean circulation disrupted, disrupting and having unknown effects on world climate.
Higher sea level leading to flooding of low-lying lands and deaths and disease from flood and evacuation.
Deserts get drier leaving to increased desertification.
Changes to agricultural production that can lead to food shortages.
Water shortages in already water-scarce areas.
Starvation, malnutrition, and increased deaths due to food and crop shortages.
More extreme weather and an increased frequency of severe and catastrophic storms.
Increased disease in humans and animals.
Increased deaths from heat waves.
Extinction of additional species of animals and plants.
Loss of animal and plant habitats.
Increased emigration of those from poorer or low-lying countries to wealthier or higher countries seeking better (or non-deadly) conditions.
Additional use of energy resources for cooling needs.
Increased air pollution.
Increased allergy and asthma rates due to earlier blooming of plants.
Melt of permafrost leads to destruction of structures, landslides, and avalanches.
Permanent loss of glaciers and ice sheets.
Cultural or heritage sites destroyed faster due to increased extremes.
Increased acidity of rainfall.
Earlier drying of forests leading to increased forest fires in size and intensity.
