What is Climatic Change
Climate change refers to the long-term alteration of
Earth's average weather patterns, particularly the
increase in global temperatures and alterations in
precipitation, wind patterns, and other climate indicators.
It is primarily driven by human activities, such as the
burning of fossil fuels (coal, oil, and natural gas),
deforestation, industrial processes, and agriculture, which
release greenhouse gases (GHGs) like carbon dioxide
(CO2), methane (CH4), and nitrous oxide (N2O) into the
atmosphere.
The accumulation of these greenhouse gases in the atmosphere
traps heat, leading to the greenhouse effect, which is essential for
maintaining a habitable temperature on Earth. However, human
activities have intensified this effect, causing an enhanced
greenhouse effect and global warming.
The consequences of climate change are widespread and can be
seen in various ways:
1. Rising global temperatures: Average temperatures have been
increasing, resulting in more frequent and intense heatwaves.
2. Melting ice and rising sea levels: Higher temperatures have
led to the melting of glaciers and polar ice caps, contributing to
rising sea levels. This can result in the flooding of coastal areas
and the loss of habitats for many species.
3. Extreme weather events: Climate change has been linked to
an increase in the frequency and severity of extreme weather
events, such as hurricanes, droughts, floods, and wildfires.
4. Ocean acidification: The absorption of excess CO2 by the
oceans leads to increased acidity, negatively affecting marine life,
particularly organisms with calcium carbonate shells, like corals
and shellfish.
