Economic Impact of Climate Change

Climate change is the most solemn environmental impendence nowadays means the
disruption in the long term seasonal weather patterns. It is related to greenhouse effect
and allied global warming, increasing levels of Carbon dioxide and greenhouse gases.
It’s true that climate change is nothing new in Earth's history. But previous changes
occurred over millions of years, not decades.
Climate change should really be entitled "Climate destabilization". It’s created more
frantic and frequent blizzards, heat waves, and other forms of extreme weather like
tornadoes, wildlifes, hurricanes, floods and landslides, and droughts.
Scientists estimated that if temperatures only elevated 2° Celsius, global GDP would
collapse 15%. It would decline by more than 30% from 2010 levels by 2100. That's
pernicious than the "Great Depression", where global trade fell 25%. The only odds is
that it would be perpetual. The industries most at jeopardy are agriculture, fisheries,
and forestry. Severe rainfall events snowstorms, drought can delay planting and
harvesting, destroy crops and precede to food insecurity. The World Food Program
found that almost half of Central American immigrants left because there wasn’t enough
food.
A 2019 study found that a warming ocean has shoved global fish yields down 4% since
1920. Many species are browbeated with extinction. It also affects the $100 billion
fishing industry and the 56 millions people employed.
Sea-level rise, floods, droughts, wildfires and extreme storms crave extensive
recuperation of exigent infrastructures such as homes,roads,bridges, power
lines,seawalls etc. Climate related health hazards also exclude productivity such as
when utmost limit heat curtails construction or when more potent allergies and more
air pollution lead to lost work and school days.
Climate change is conjoining to the number of "climate refugees" -people who are
strained to leave their homes because of climate kindred disasters. Since 2008,
extreme weather has evicted 22.5 millions of people according to the United Nations
High Commissioner for Refugees. By 2050, climate change will force 700 million people
to emigrate.
Don't know should it be called complacence or not, efforts to stop climate change would
hatch 24 million new jobs by 2030!
Studies show that rebuilding after disasters strike is likely to prove even more pricey
than preventive measure. The World should find better solutions to assuage the
economic cost of climate change.
