can you please help me to answer the above question

Answer:
1.) Global warming is expected to have far-reaching, long-lasting and, in many cases, devastating consequences for planet Earth.
Global warming, the gradual heating of Earth's surface, oceans and atmosphere, is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide (CO2), methane and other greenhouse gases into the atmosphere.
Despite political controversy about climate change, a major report released Sept. 27, 2013, by the Intergovernmental Panel on Climate Change (IPCC) stated that scientists are more certain than ever of the link between human activities and global warming. More than 197 international scientific organizations agree that global warming is real and has been caused by human action.
Already, global warming is having a measurable effect on the planet.
2.) The gradual increase in the overall temperature of Earth's atmosphere due to the greenhouse effect. This effect is caused by increased levels of carbon dioxide, chlorofluorocarbons and other gases in the air, many of them released by human activity.
3.) Carbon Dioxide - Fossil fuel combustion; Deforestation; Cement production
Methane - Fossil fuel production; Agriculture; Landfills
Nitrous Oxide - Fertilizer application; Fossil fuel and biomass combustion; Industrial processes
Chlorofluorocarbon-12 (CFC-12) - Refrigerants
4.) warmer temperatures increase transmission of vector-borne disease up to an optimum temperature or “turn-over point,” above which transmission slows. Just as they carry different diseases, different mosquitoes are adapted to a range of temperatures.
Answer:
1)Global Warming
2)when the sunlight enters the earth's atmosphere it got trapped by the green house gases due to which temperature rises and leads to global warming
3)a) Carbon Dioxide Fossil fuel combustion; Deforestation; Cement production
b)Methane Fossil fuel production; Agriculture; Landfills
c)Nitrous Oxide Fertilizer application; Fossil fuel and biomass combustion; Industrial processes
d)Chlorofluorocarbon-12 (CFC-12) Refrigerants
e)Hydrofluorocarbon-23 (HFC-23) Refrigerants
d)Sulfur Hexafluoride Electricity transmission
e)Nitrogen Trifluoride Semiconductor manufacturing
4) The human body requires evaporative cooling to prevent overheating, even with a low activity level. With excessive ambient heat and humidity, adequate evaporative cooling does not take place. Human thermoregulatory capacity is exceeded. A sustained wet-bulb temperature or Wet-bulb globe temperature exceeding about 35 °C (95 °F) can be fatal.
Human response to heat stress can be hyperthermia, heat stroke and other harmful effects. Heat illness can relate to many of the organs and systems including: brain, heart, kidneys, liver, etc.
Warming oceans and a changing climate are resulting in extreme weather patterns which have brought about an increase of infectious diseases—both new and re-emerging. These extreme weather patterns are creating extended rainy seasons in some areas,and extended periods of drought in others, as well as introducing new climates to different regions.These extended seasons are creating climates that are able to sustain vectors for longer periods of time, allowing them to multiply rapidly, and also creating climates that are allowing the introduction and survival of new vectors.
