What
is Global Warming?
Since
the Industrial Revolution, the global annual temperature has increased in total
by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. The
first accurate records were kept in the year 1880, and between that year and
1980, the temperature increased by an average of 0.07 degrees Celsius (0.13
degrees Fahrenheit) every 10 years. Since 1981, however, the rate of increase
has more than doubled: over the past four decades, we have seen a rise in the
average annual temperature across the globe of 0.18 degrees Celsius, which is
equivalent to 0.32 degrees.
A
planet with temperatures that have never been higher. Since 1880, nine of the
ten years with the warmest temperatures on record have occurred since 2005, and
the five years with the warmest temperatures on record have all taken place
since 2015. Deniers of climate change have argued that there has been a
"pause" or a "slowdown" in the rising global temperatures,
but numerous studies, including a paper published in 2018 in the journal
Environmental Research Letters, have disproved this claim. People all over the
world are already suffering as a result of the effects of global warming.
Now,
climate scientists have concluded that we must limit global warming to 1.5
degrees Celsius by the year 2040 if we are to avoid a future in which everyday
life around the world is marked by the worst and most devastating effects of
climate change. These effects include extreme droughts, wildfires, floods,
tropical storms, and other disasters that we refer to collectively as climate
change. These effects are experienced by all people in some way or another, but
they are felt most acutely by the underprivileged, the economically marginalized,
and people of color. This is because climate change is often a key driver of
poverty, displacement, hunger, and social unrest for people of color.
Causes
of Global Warming
1. Deforestation
The
vast majority of oxygen comes from plant life. They contribute to the
maintenance of environmental equilibrium by taking in carbon dioxide and giving
off oxygen. Many residential and commercial uses are contributing to the
depletion of forest resources. This has resulted in an environmental imbalance,
which in turn has led to the acceleration of global warming.
2. Use
of Vehicles
Even
when used for very short distances, vehicles produce a variety of gaseous
emissions. These emissions can be harmful to the environment. When fossil fuels
are burned in vehicles, they release a significant amount of carbon dioxide as
well as other harmful toxins into the atmosphere. This causes the temperature
to rise.
3. Chlorofluorocarbon
The
excessive use of air conditioners and refrigerators by humans has resulted in
the addition of CFCs to the environment, which in turn affects the ozone layer
in the atmosphere. The ozone layer acts as a barrier between the surface of the
earth and the potentially damaging ultraviolet rays that are emitted by the
sun. CFCs are to blame for the thinning of the ozone layer, which has allowed
more ultraviolet radiation to reach the surface of the earth and contributed to
its overall warming.
Ways
to Stop Global Warming
1. Be
sure to check your tyres
It
is possible to improve your vehicle's gas mileage by more than 3 percent simply
by maintaining the correct tyre pressure. The removal of one gallon of gasoline
from circulation prevents the emission of twenty pounds of carbon dioxide into
the atmosphere.
2. Use
less hot water
Heating
water consumes a significant amount of energy. You can reduce the amount of hot
water you use by taking showers that are shorter and cooler, and by washing
your clothes in cold or warm water rather than hot water (more than 500 pounds
of carbon dioxide saved per year).
3. Products
that come in a lot of packaging should be avoided
If
you reduce the amount of garbage you produce by just 10%, you'll prevent the
emission of 1,200 pounds of carbon dioxide.
4. Change
the settings on your thermostat
Changing
the temperature on your thermostat by just 2 degrees, either down in the winter
or up in the summer, can save you about 2,000 pounds of carbon dioxide over a
year.
5. Grow
some trees
During
its lifetime, a single tree will be responsible for the absorption of one tonne
of carbon dioxide.
