The enhanced greenhouse
effect leads to the abnormal warming of the Earth’s
surface. This results to a change in climatic patterns
around the world, hence
the name, climate change.
Climate includes long-term patterns of temperature, precipitation, rainfall, humidity and wind patterns. Much of the changes have been attributed to anthropogenic factors (burning of fossil fuels and deforestation).
Rising levels of greenhouse gases (CO2, methane, etc.) increased the temperature of the Earth’s surface causing massive impacts such as melting of polar ice caps, rising sea levels, erratic weather disturbances and severe floodings in vulnerable areas.
Changing climatic conditions drastically affected the natural ecosystems and the human communities that relied on them.
