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
