Question

what are the causes and effects of global warming?​

Answer 1

Answer:

Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. Between 1880—the year that accurate recordkeeping began—and 1980, it rose on average by 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10 years. Since 1981, however, the rate of increase has more than doubled: For the last 40 years, we’ve seen the global annual temperature rise by 0.18 degrees Celsius, or 0.32 degrees Fahrenheit, per decade.

Answer 2

Answer:

Causes of global warming:

• Global warming occurs as a result of the increased concentration of greenhouse gases in the atmosphere.
• Greenhouse gases include carbon dioxide, methane, and water vapour.
• These gases trap solar radiations released back by the Earth.
• This helps in keeping our planet warm and thus, helps in human survival.
• However, an increase in the amount of greenhouse gases can lead to an excessive increase in the Earth’s temperature, leading to global warming.
• Global warming is a result of industrialization, burning of fossil fuels, and deforestation.  

Effects of global warming:

• Global warming is defined as an increase in the average temperature of the Earth’s surface.
• It has been observed that in the past three decades, the average temperature of the Earth has increased by 0.6ºC.
• As a result, the natural water cycle has been disturbed resulting in changes in the pattern of rainfall.
• It also changes the amount of rain water.
• Also, it results in the melting of Polar ice caps and mountain glaciers, which has caused a rise in the sea level, leading to the inundation of coastal regions.
