Global warming refers to the rise
in global temperatures due mainly to the increasing concentrations of greenhouse
gases in the atmosphere.
Climate change refers to the
increasing changes in the measures of climate over a long period of time including
precipitation, temperature, and wind patterns.
So, global warming one aspect of
climate change.
Here are the consequences of
global warming and climate change to our environment and survival:
Continuous rise in temperature: Global
warming endlessly increases average air temperatures near the surface of Earth.
Heat-waves: Prolonged periods of
abnormally high temperatures can have serious health effects on vulnerable
populations, such as the elderly and the sick. The most common health effect is
hyperthermia or heatstroke that can be fatal if left untreated. Global warming
will lead to hot days, followed by nights of high temperatures.
Sea level rise: This is the
result of added water from melting land ice and the expansion of seawater as it
warms. Storm surges and high tides could combine with sea level rise and land
subsidence to further increase flooding in many regions. Ocean waters will
therefore continue to warm and sea level will continue to rise.
Increase in heavy precipitation:
This refers to instances during which the amount of rain or snow experienced in
a location substantially exceeds what is normal. Climate change can affect the
intensity and frequency of precipitation. Warmer oceans increase the amount of
water that evaporates into the air. When more moisture-laden air moves over
land or converges into a storm system, it can produce more intense
precipitation—for example, heavier rain and snow storms. This leads to crop
damage, soil erosion, and an increase in flood risk due to heavy.
Decline in Arctic sea ice and
snow cover: In recent years, global warming has led to a decrease in the area
of Arctic ice, which has caused the world's marine powers to pay unprecedented
attention to the Arctic.
Glacier recession and retreat: Glaciers
are retreating, shrinking, and disappearing worldwide due to global warming. The
retreat of glaciers affects landscape configuration, water availability, and
natural hazards, impacting downstream ecosystems and society. Therefore, plants
inhabiting proglacial environments are highly sensitive to global warming and
inherent glacier retreat. Understanding how plant communities are responding to
ongoing glacier recession is crucial for projecting biodiversity dynamics and
planning sustainable ecosystem management.
Infectious diseases: Global
warming worsens human health conditions, especially in tropical regions. In
places like Africa, an increase in temperature signifies an increase in
mosquito populations, thus escalating the risk of malaria, dengue and other
insect-borne infections. Other regions are also affected. The United States
experienced varying levels of malaria outbreaks; in 2006, the United Kingdom
was plagued by an outbreak of legionnaires' diseases -- a bacterial lung
infection that scientists attribute to global warming.
Loss of agricultural
productivity: Global warming results in droughts that can worsen living
conditions, particularly in Africa. Climate change drastically alters rainfall
pattern, and risk water and food supplies for millions. Rising temperatures
results in food shortages.
Asthma and other respiratory
diseases: People suffering from heart problems are more vulnerable to increased
temperatures, especially those living in already warm areas, as their
cardiovascular system must work harder to keep their body cool. Hot
temperatures increase the ozone concentration, which can damage people's lung
tissue and cause complications for asthma patients and those with lung
diseases.
Treat to national security: Increased
global warming can also pose a threat to national security, affecting food
security, which, in turn, can lead to resource conflicts. Loss of basic needs
due to climate change in poor countries can increase the risk of conflicts. It
also causes aggression by the rich against the poor.
Increase in the proportion of
violent tropical cyclones: Intensity of tropical cyclones is increasing due to
climate change. Climate change is fueling more powerful hurricanes and
typhoons, a trend that is expected to continue as global temperatures rise.
