global warming

you global warming and climate change global  warming global warming is a climatological  

phenomenon in which the global temperature is  rising because of increasing concentrations of  

greenhouse gases in the atmosphere wire if the  surface is warming our Sun which is reasonably  

hot sends us a mixture of various rays which  is composed for 10% of UV 40% of visible  

light and 50% of infrared when the incoming  solar radiation arrives at the top of the  

atmosphere it is directly reflected towards  space by clouds and the various layers of  

the atmosphere the remainder of this incoming  energy is absorbed by the various components  

of our planet such as atmosphere earth surface  ocean etc since the Earth's surface is colder  

than the Sun it radiates heat back to the  atmosphere in the form of infrared energy

most of the emitted infrared radiation is  absorbed by the atmosphere and warms in  

so the atmosphere also gains heat and radiates  energy both upwards and downwards the downward  

radiation is absorbed by the Earth's surface and  the upward radiation is reflected back to space

as we know our atmosphere of earth is a  layer of gases which contains roughly 78%  

nitrogen 21% oxygen 0.97% argon 0.04  percent carbon dioxide trace amounts  

of other gases in water vapor nitrogen and  oxygen that form most of the atmosphere do  

not absorb the infrared radiation so they  do not contribute to warming the earth

but the greenhouse gas molecules mainly  carbon dioxide and water vapor absorbed  

the sun's radiation as infrared  some goes back into outer space  

and most of the energy towards the Earth's surface

thus the greenhouse gases warming up the  atmosphere and also the Earth's surface which  

is called greenhouse effect in this way the earth  maintains a stable average temperature without  

these greenhouse gases surface temperatures  would be cooler and many life forms would freeze

thanks to this natural greenhouse gases because  it keeps our average temperature is comfortable  

when the concentrations of greenhouse  gases increase then when a temperature  

of the atmosphere also be increased which  leading to the warming of the Earth's surface

because too much greenhouse gases trap more and  more radiations that cannot escape to the space  

as a result radiations remain in our Earth's  atmosphere this causes earth to warm up so  

the higher concentrations of greenhouse gas  responsible for global warming contributors  

of the greenhouse gases both nature and human  activities are the main contributors for the  

emission of greenhouse gases volcanic eruption  power plant plants industry ocean transportation

forest fire deforestation live stocks  commercial and residential equipments

impacts of the global warming global warming  leads to long-term and devastating impacts for the  

natural environment ecosystems and human societies  such as drought flood storm ice melting etc

effects on ocean and climate  change as temperatures rise  

glaciers melt faster than they accumulate new snow

when these ice sheets and glaciers meld the  water flows into the oceans and sea level rise

sea-level rise cause destructive erosion  flooding of wetlands aquifer and agricultural  

soil contamination with salt otherwise  rising water level helps to evaporate more  

water vapors from the warm ocean surface  hurricane or cyclone get the energy for  

winds from these warm water vapor and leads to  higher wind speeds in the hurricane or cyclone

nevertheless when carbon dioxide enters the ocean  it combines with seawater to produce carbonic  

acid which increases the acidity of the water  lowering its pH this is called ocean acidification

the rising temperatures coupled with ocean  acidification affect marine species and  

ecosystems warmer water temperatures in ocean  result in coral bleaching when water is too  

warm corals will expel the algae living in their  tissues causing the coral to turn completely white  

effects on animals wild animals and birds face new  challenges for survival because of global warming

due to drought induced starvation many wildlife  animals shift their places for searching food  

and water birds also migrate to move from area  to another area for their resources polar bears  

are starving because of melting sea ice they need  sea ice to hunt seals as their main source of food

effects on human health the human health  is put at risk because of global warming

rising temperatures in the tropics  allow mosquitoes to thrive causing  

the spread of diseases like dengue  fever zika chikungunya malaria heat  

waves caused people to die of dehydration  or heatstroke global warming solutions

renewable energies like wind  power solar energy hydropower  

have the potential to reduce global warming

decrease the emission of carbon dioxide from  industry sectors turned to reduce global warming

planting more trees can play a significant role  

by reducing carbon dioxide from the air  and releasing oxygen into the atmosphere

to avoid the use and emissions of CFCs or  HFCS a variety of climate friendly energy  

efficient safe and proven alternatives  need to use.
