a. More extreme weather pattems.
b. Retreat of glaciers.
c. An increase of UVB radiations.
d. An increase in sea level.
Help me clarify my doubts please... My kind request... ​

Answer 1

Answer:

Climate change is predicted to change many environmental conditions that could affect the properties of fresh and marine waters. These changes could favor the growth of harmful algal blooms and habitat changes

Answer 2

An increase in UV-B radiation is not a potential adverse effect of global warming (Option - c).

• Global warming is defined as the increase in the temperature of the Earth's atmosphere due to the greenhouse effect.
• The Greenhouse effect is caused due to entrapment of heat reaching the Earth which does not let reflected heat radiations go out of the Earth's atmosphere leading to a warming effect.
• The Greenhouse effect is caused due to Greenhouse gases such as carbon dioxide, water vapor, methane, and nitrous oxide.
• These form a layer or covering that prevents heat radiation from exiting the Earth's atmosphere.
• The Major gas responsible is carbon dioxide which leads to an increase in global temperature leading to Global warming.
• These are not responsible for let particular radiation go out or come in, mostly infrared radiations are capable of reaching back after getting reflected.
• The Ozone layer in the troposphere is responsible for protecting us from harmful UV rays of the sun.
• Depletion of the Ozone layer is the cause of the increase in UV-B radiations entering the Earth.
• Depletion of the Ozone layer is caused due to emissions of CFCs - chlorofluorocarbons from aerosols, air conditioners, refrigerators, etc.
• Hence, global warming does not cause an increase in UVB radiation.
• Global warming or heating of Earth can lead to the melting of Glaciers, further leading to rising sea levels and climate change or extreme weather patterns.
