Climate change has been
widely discussed over the past few years and for a good reason. It is a complex
issue that affects the entire planet, from the atmosphere to the oceans and
everything in between. Various factors, including natural processes and human
activities, cause climate change. This article will explore the science behind
climate change, its impacts on the planet, and how we can mitigate its effects.
The main villain of
climate change is the atmospheric release of greenhouse gases like carbon
dioxide. Increased global temperatures result from these gases' ability to trap
solar heat and prevent it from escaping into space. Although some greenhouse
gases are required for life to exist on Earth, human actions like burning
fossil fuels and deforestation have significantly boosted atmospheric
concentrations of these gases.
All around the world,
the effects of climate change are already being felt. Sea levels are rising,
and ocean currents are changing due to the Arctic's alarming melting rate. The
annual cost of damage from extreme weather events like hurricanes, floods, and
droughts is billions of dollars. The oceans are becoming more acidic,
threatening marine ecosystems and the millions of people who depend on them for
their livelihoods.
Causes Of Climate
Change
Now we will discuss how
climate is changing and what are the roles of humans in affecting climate
change.
Burning Of Fossil Fuels
Human activities
contributing to climate change include burning fossil fuels, such as coal, oil,
and gas, which release large amounts of CO2 into the atmosphere. Deforestation
also contributes to climate change because trees absorb CO2 as part of
photosynthesis, and when they are cut down or burned, the stored carbon is
released into the atmosphere. Agriculture also contributes to climate change
through activities such as livestock production and the use of fertilizers,
which release CH4 and N2O into the atmosphere.
Natural Factors
Natural factors
contributing to climate change include volcanic activity, which releases large
amounts of gases and particles into the atmosphere that can cool the planet
temporarily, and solar radiation, which can affect the amount of heat and
energy the Earth receives from the sun. Other natural factors include changes
in the Earth's orbit and tilt, which can affect the amount of sunlight that
different regions of the planet receive, and natural variations in the Earth's
climate system, such as changes in ocean currents and atmospheric circulation
patterns.
Effects Of Climate
Change
After getting caused by
human activities and natural disasters, what are the effects of these changes
on the climate? Here are briefly discussed:
Global Temperature
Rising global
temperatures are caused by the accumulation of greenhouse gases in the
atmosphere, primarily carbon dioxide, which trap heat from the sun and cause
the Earth's temperature to rise. In recent years, global warming has caused
high temperatures worldwide. For instance, in July 2021, Lytton, a small town
in British Columbia, Canada, recorded a temperature of 49.6°C (121.3°F), the
highest temperature ever recorded in Canada. Similarly, in August 2020, Death
Valley, California, recorded a temperature of 54.4°C (130°F), one of the
highest temperatures ever recorded on Earth. In addition to North America, many
parts of Europe, Asia, and Africa have experienced extreme heat waves in recent
years, causing severe heat-related health issues.
Sea Levels
Rising sea levels are
also a consequence of global warming, as warmer temperatures cause glaciers and
ice caps to melt and contribute to the expansion of seawater. This can lead to
the flooding of coastal areas and the erosion of beaches, threatening homes,
infrastructure, and communities.
Threats To Ecosystems
As temperatures rise, it
can disrupt the delicate balance of ecosystems, causing species to shift their
ranges or become endangered or extinct. Baiji Dolphin was once found in the
Yangtze River in China, but it was declared functionally extinct in 2006 due to
habitat loss and pollution caused by climate change.
The Golden Toad was once
found in the cloud forests of Costa Rica, but it has not been seen since 1989
due to the warming and drying of its habitat.
The Bramble Cay Melomys,
a small rodent, was declared extinct in 2016 due to rising sea levels and storm
surges caused by climate change.
Solutions to Climate
Change
We have to take steps to
control climate change because it can be disastrous for our Earth shortly.
Mitigating the Impacts
of Climate Change
The effects of climate
change must be mitigated, which calls for a global effort by people, companies,
and governments. Switching to sustainable energy sources, including wind and
solar electricity, is one of the most efficient ways to reduce greenhouse gas
emissions.
This requires
significant investments in infrastructure and research and development, but the
long-term benefits to the planet and future generations are immeasurable.
Reduce Fossils Fuels
Another critical step is
reducing our reliance on fossil fuels, the primary source of greenhouse gas
emissions. This can be achieved by promoting energy efficiency measures, such
as better insulation and more efficient appliances, and by encouraging public
transportation and alternative modes, such as biking and walking.
The Role of Governments
in Addressing Climate Change
To combat climate
change, numerous governments all over the world have already taken action.
Countries committed to limiting global warming to far below 2 degrees Celsius
above pre-industrial levels and to pursue measures to restrict the temperature
increase to 1.5 degrees Celsius under the Paris Agreement, which was signed in
2015. To achieve these goals, further work must be done.
Using Public
Transportation
Taking the bus or train
instead of driving your automobile is one of the most effective ways to lessen
your carbon footprint. Public transit, like buses, trains, and subways, emits
less carbon dioxide per passenger than a car. You may also save money by taking
public transportation by avoiding paying for gas and auto repairs.

Climate Change and
Public Health
Climate change is not
just an environmental issue but also a significant threat to public health. The
following sections will discuss the impact of climate change on public health
and strategies to protect public health in the face of climate change.
Spread of Disease
Rising temperatures and
changing weather patterns can create favourable conditions for disease-carrying
insects like mosquitoes and ticks. As a result, diseases like malaria, dengue
fever, and Lyme disease are on the rise.
Air Pollution
Climate change exacerbates
air pollution, contributing to respiratory diseases like asthma, chronic
obstructive pulmonary disease (COPD), and lung cancer. Warmer temperatures also
increase the formation of ground-level ozone, a potent respiratory irritant.
Extreme Weather Events
Climate change is
responsible for more frequent and severe weather events like heat waves,
floods, and hurricanes. These events can cause injury, illness, and death,
disrupt health services and increase the risk of food and waterborne diseases.
FAQS
1-What is the most
significant contributor to climate change?
The increase in
greenhouse gas emissions, principally carbon dioxide (CO2), brought on by human
activities, including burning fossil fuels for energy, deforestation, and
industrial operations, is the leading cause of climate change. Global warming
is caused by these emissions, which trap heat in the planet's atmosphere and
significantly negatively influence the natural world and human culture.
2-How do we know that
climate change is happening?
There is a wealth of
evidence that climate change is happening, including Increasing global
temperatures, Rising sea levels, and extreme weather events such as floods,
droughts, and heatwaves.
Conclusion
Climate change is a
critical issue that requires urgent action. Governments, businesses, and
individuals all have a role in addressing it. Transitioning to a low-carbon
economy will require significant investments in renewable energy, energy
efficiency, and other climate-friendly technologies. However, the benefits of
addressing climate change far outweigh the costs. By taking action now, we can
mitigate the worst impacts of climate change and create a better future for
ourselves and future generations.
