and Solutions
We are surrounded by evidence that climate change is occurring. Although the earth's
climate is changing, it is clear that these changes are having a disastrous effect on a
great number of people, places, and animals. Read on to discover more about the
causes, impacts, and workable solutions to halting climate change, as well as its
definition and the reasons it matters.
What Is Climate Change?
It's likely that you've heard the terms global warming and climate change used
interchangeably. This is so because they both discuss how the earth's climate
fluctuates. While the focus of global warming is on the planet's average temperature
rising, climate change typically refers to changes in precipitation, wind patterns, and
temperature during a specific time period. Climate changes that are measured may
occur over a few years, several decades, or even millions of years.
For as long as the world has existed, climate change has happened. It occurs whenever
changes in the earth's climate patterns persist for a quantifiable period of time. This is
particularly evident in the natural warming and cooling cycles. Five primary elements
interacted with one another prior to human causes beginning to alter the global climate.
These five factors include: [1]
1. Atmosphere (air)
2. Biosphere (living things)
3. Cryosphere (ice and permafrost)
4. Hydrosphere (water)
5. Lithosphere (earth’s crust and upper mantle)
What Are the Causes of Climate Change?
"The scientific evidence is clear: global climate change caused by human activities is
occurring now, and it is a growing threat to society," according to the American
Association for the Advancement of Science [2].
A handful of the ways that people are hastening climate change are listed below.
, Greenhouse Gasses
An essential component of the earth's climate cycles are greenhouse gasses. Part of
the energy that the sun's rays strike the planet is absorbed, while the remaining heat
and energy are reflected into space. The reflected energy is eventually redirected back
down to Earth by greenhouse gasses in the atmosphere, which traps it and causes
global warming. This is the role of a variety of gasses, including:[3]
● Vapour of water
● CO2 (carbon dioxide)
● Methane
● nitrous oxide
● CFCs, or chlorofluorocarbons
Certain greenhouse gasses are produced artificially, like CFCs, but others, like water
vapour, are found naturally. CO2 is one of the main contributors to climate change and
is released into the atmosphere by both natural and man-made processes. If CO2
doesn't get absorbed by the ocean, land, trees, and other sources, it will likely remain in
the earth's atmosphere for thousands of years at this frightening rate. But the earth's
natural capacity to absorb CO2 has also decreased while its output has risen gradually
[4]. Earth's resources are already diminishing due to factors like deforestation, therefore
this is already happening in many ways. According to certain research, soil and plants
will be able to absorb less CO2 as the earth continues to warm—possibly accelerating
climate change even further. [5]
Solar Activity
As was already noted, solar activity affects the earth's climate. Although the sun goes
through natural cycles in which its energy output to the earth increases and decreases,
it seems doubtful that solar activity has a significant role in climate change or global
warming. There hasn't been a discernible increase in the amount of solar radiation
entering our atmosphere since scientists started measuring it.[6]
Deforestation
Climate change and deforestation frequently go hand in hand. In addition to increasing
deforestation due to wildfires and other extreme weather events brought on by climate
change, deforestation plays a significant role in global warming. Deforestation is the
second largest source of greenhouse gas emissions worldwide, according to the Earth
