Steps Towards Solving Climate Change By 2050
Climate change is a norm that needs immediate action, with it being the most alarming concern of the present times. The most striking finding was that even when the solutions are modeled using a "Plausible Scenario"—a conservative measure of projected solution implementation that is "reasonable yet optimistic"—society still makes significant progress toward achieving drawdown, the point at which greenhouse-gas levels in the atmosphere begin to decline.
In the
Plausible Scenario, all 80 remove or sequester 1,051 gig tons of carbon by
2050. They eliminate or sequester 1,442 gig tons of carbon by 2050 using the
scenario that takes us to drawdown—which involves scaling up the solutions a
little more than the cautious estimate, notably renewable energy.
Top 10 steps
to solve climate change by 2050:
The issue is this: Chemical refrigerants are
found in every refrigerator, grocery case, and air conditioner, and they absorb
and release heat to chill food and keep buildings and cars cold. Refrigerants,
particularly chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs),
were formerly a significant contributor to the depletion of the stratospheric
ozone layer necessary for absorbing ultraviolet radiation from the sun. Since
the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer, CFCs and
HCFCs have been phased out of usage.
Progress on solutions: Officials from almost 170
nations met in Kigali, Rwanda, in October 2016 to negotiate a solution to solve
the problem of HFCs. Despite the difficulties of global politics, they were
able to strike a stunning accord. Unlike the Paris Climate Agreement, the
Kigali agreement is binding, with defined goals and deadlines. The world will
phase out HFCs through an amendment to the Montreal Protocol, starting with
high-income nations in 2019 and then spreading to low-income countries—some in
2024, others in 2028. Natural refrigerants like propane and ammonia, as well as
HFC alternatives, are already on the market.
The issue: During the mid-twentieth
century, fossil fuels pushed zero-emission wind energy to the sidelines. Wind
energy isn't without its drawbacks. The weather is different in many parts of
the world. Because wind is so unpredictable, there are periods when turbines
aren't turning. Turbines, according to critics, are loud, visually unappealing,
and, in some cases, fatal to bats and migrating birds.
Progress on solutions: Currently, 314,000 wind
turbines provide 3.7 % of the world's power. It will be much more in the
not-too-distant future. Despite a significant reduction in fossil-fuel costs,
the globe constructed a record 63 gig watts of wind power in 2015. Wind energy
is either competitive with or less priced than coal-fired power in many places.
Just
three states in the United States—Kansas, North Dakota, and Texas—have enough
wind energy potential to fulfil electrical demand from coast to coast.
The issue: A third of the food produced
or prepared never makes it from farm to fork. And here's another: Every year,
we release 4.4 gig tons of CO2-equivalent into the atmosphere, accounting for
about 8% of total human greenhouse-gas emissions. That figure is astounding,
especially when compared to the following: Hunger is a reality for
approximately 800 million people worldwide.
Progress on solutions: The Sustainable Development
Goals of the United Nations aim to decrease global per capita food waste at
retail and consumer levels by 2030 and minimize food losses along production
and supply chains.
4. Consumption of a Plant-Based Diet
The issue is this: The Western diet comes at a
high cost in terms of climate change. According to the most conservative
estimations, animal production accounts for over 15% of global greenhouse gas
emissions each year; the most thorough evaluations of direct and indirect
emissions put the figure at more than 50%.
Aside
from the creative, carbon-sequestering managed-grazing techniques discussed in
another area of drawdown drawdown, meat and dairy production emits far more CO2
than cultivating sprouting vegetables, fruits, grains, and legumes.
Progress on solutions: Imagine how many
possibilities there are to turn the tables with billions of people eating many
times a day. It is feasible to eat healthily in nutrition and enjoyment while
also decreasing emissions by eating lower on the food chain.
The issue is this: Tropical forests, defined as
those lying within 23.5 degrees north or south of the equator, have seen
considerable clearance, fragmentation, degradation, and flora and fauna loss in
recent decades. They used to cover 12% of the world's landmasses, but
currently, they only cover 5%.
Carbon
dioxide is released into the atmosphere when forests are lost, mainly due to
agricultural development or human settlement. The destruction of tropical
forests accounts for 16 to 19 % of human-caused greenhouse gas emissions.
Progress on solutions: The restoration of tropical
forests, both passive and active, is becoming increasingly popular. Trees,
soil, leaf litter, and other plants absorb and retain carbon when forest
ecosystems re-establish themselves, removing it from the global-warming cycle.
The issue: Today, almost 130 million
girls are denied their fundamental right to attend school and build a
foundation for their life. The situation is particularly bad in secondary
schools.
Lack
of family finances for school tuition and uniforms, as well as a preference for
the more immediate benefits of having girls carry water or firewood, or operate
a market stall or a plot of land, are also economic hurdles.
The issue is this: Securing the fundamental
right to voluntary, high-quality family-planning services so that women can
have children of their choosing rather than by accident and manage their family
size and spacing is a question of autonomy, dignity, and, yes, climate change.
Currently,
the globe is facing a $5.3 billion financing gap to provide the reproductive
health care that women say they desire. After more than 25 years of silence on
the subject of family planning, the UN Intergovernmental Panel on Climate
Solutions in Progress: The success stories in the
field of family planning are impressive. In the early 1990s, Iran implemented a
program that has been hailed as one of the most effective in history. It was
completely voluntary and featured religious leaders, public education, and free
contraception.
The issue: The era of fossil fuels is
finished, and the only question now is when we will enter the new era of
renewable energy. At the moment, solar photovoltaic account for only 2% of
worldwide power generation.
Progress on solutions: Solar farms are large-scale
arrays of hundreds, thousands, or even millions of panels producing capacity in
the tens or hundreds of megawatts. These solar farms provide electricity at a utility scale, similar to that produced by conventional power plants.
The issue: Ranching is being vilified as
a cause of enormous deforestation and climate change in Brazil and worldwide.
Cattle and other ruminants use 30 to 45 % of the world's arable land, and
livestock accounts for around one-fifth of global greenhouse gas emissions.
Progress on solutions: Cows and trees, according to
conventional belief, do not belong together. Silvopasture defies this concept
of reciprocal exclusivity, and it has the potential to usher in a new era for
land dedicated to cattle and their sustenance.
The issue: The era of fossil fuels is
finished, and the only question now is when we will enter the new era of
renewable energy. At the moment, solar photovoltaic account for only 2% of
worldwide power generation.
Progress on solutions: Over the last decade, solar
photovoltaic (PV) has grown exponentially. Distributed systems with a capacity
of fewer than 100 kilowatts accounted for about 30% of all solar PV capacity
added globally in 2015.
Conclusion:
Climate change is alarming, and we need to act on it today in
order to have a secured future for us and our loved ones. Implement these tips
to fight climate change by 2050.
