Climate the sea levels to rise and pose

change has been a controversial issue where people hold various opinions about.
However, in recent times, there has been overwhelming evidence indicating
climate change is real due to the warning trend in our climate resulting into
the melting of earth’s glaciers and ice caps which will in turn, cause the sea
levels to rise and pose an imminent threat to coastal regions. It is now
understood that the earth’s climate is warming up, the arctic is melting, while
the drought and flood patterns are changing, and these changes will radically
increase over the years (IPCC, 2007) . There is a strong debate in our society
about the occurrence of climate change. According to Blunden and Arndt (2017),
climate change is happening because there was an increase of about 0.01oC in sea surface temperature at the global scale, as
against 2015 record. Bluden and Arndt (2017) point out that there was constant
heavy flooding in Argentina, Paraguay, and Uruguay as a result of wet
conditions across southern South America all through the year. Bluden and Arndt
(2017) further states that ‘Wetter-than-usual conditions were also observed for
eastern Europe and central Asia alleviating the drought conditions or worse,
the longest such stretch in the record’.

suggests that climate change is a valid threat because the health of the ocean
is failing due to increased temperature, causing mass deaths of fish and the
overgrowth of dangerous algae. Currently, there
is an extraordinary increase in the warming trend since the mid 20th
century and most likely (greater than 95 percent probability) can be attributed
to human activity (IPCC, 1996). Adequate evidence that climate change exists
can be drawn from the satellite observation of the National Snow and Ice Data
Center (2013) which reveals that the amount of spring snow cover in the
Northern Hemisphere has decreased over the past five decades and that the snow
is melting earlier. In 2009, Levitus,, observes that with the top 700 meters
(about 2,300 feet) of ocean indicating warming of 0.302 degrees Fahrenheit
since 1969, the oceans have taken in a great deal of the increased heat.
According to the National Ocean and Atmospheric Authority (NOAA)
(YEAR) surface ocean water acid levels increased
by about 30 percent since the onset of the Industrial Revolution. This increase
is the result of human emitting more carbon dioxide into the atmosphere and
hence more being absorbed into the oceans. Sabine, (2004) mentions that
the amount of carbon dioxide absorbed by the upper layer of the oceans is
increasing by about 2 billion tons per year

fact that climate change exists can be further supported by the picture below,

Data by NASA has established key
evidence proving the reality of climate change from the Greenland and Antarctic
ice sheets which has decreased in mass. National Aeronautics and Space
Administration’s (NASA) Gravity Recovery and Climate Experiment show Greenland
lost 150 to 250 cubic kilometers of ice between 2002 and 2005.

the Greenland ice sheet (NASA, 2006)


key evidence to indicate that climate change is a valid threat can be seen in
the models used by NASA and NOAA to predict climate which generally indicate an
overall warming trend. As inferred from the report of the Working Group 1 which
states that

globally averaged surface temperatures have increased by 0.6 ± 0.2°C over the
20th century; and that, for the range of scenarios developed in the IPCC Special
Report on Emission Scenarios (SRES), the globally averaged surface air
temperature is projected by models to warm 1.4 to 5.8°C by 2100 relative to 1990,
and globally averaged sea level is projected by models to rise 0.09 to 0.88m by
2100’ (1PCC, 2001).

evidence that indicate that climate change exists and is a danger to humanity
is observed in Jarraud and Steiner’s statement. Jarraud and Steiner (2013) further support
the claim that climate change is real in the report “Climate
Change 2013: The Physical Science Basis” stating that

‘The report confirms that warming in the
climate system is unequivocal, with many of the observed changes unprecedented
over decades to millennia: warming of the atmosphere and the ocean, diminishing
snow and ice, rising sea levels and increas­ing concentrations of greenhouse
gases. Each of the last three decades has been successively warmer at the
Earth’s surface than any preced­ing decade since 1850.’ (p.v)

With so much evidence in support of the occurrence of climate
change, it is unrealistic to believe otherwise. The evidence overwhelming
supports the fact that the earth’s climate is changing significantly, resulting
into various disastrous challenges which could make the earth inhabitable if
not addressed.
