Question 1
The world has had adverse climate changes in the past without assistance from the human
race. Evidence of the past climates was left in coral reefs, layers of ice in glaciers, tree rings, and
ocean sediments as well as in sedimentary rocks layers. There have been numerous times in Earth’s
history when the global temperatures rose abruptly similarly to the way they are rising in present
days. In the past, the cause was the rapid and large emission of greenhouse gasses, just like human
beings are producing nowadays (Vuille et al., 2008). Those sudden global warming occasions were
almost all the time extremely harsh for life, leading to mass extinctions of different species of
animals such as the Permian, mid-Cambrian and the Triassic periods. The indications from those
occasions (rising sea levels, the rapid increase in global temperatures and ocean acidification) are
all occurring nowadays with the climate change being human-caused.
Question 2
There is numerous evidence of the climate change, first, rise above the sea level, the rate
of the sea level rising is high in the last two decades when compared to the last century (more than
eight inches). The global temperature has risen by 1.1 degrees, the greatest contributors are the
emissions by humans. Ice sheets are decreasing with Antarctic and Iceland losing ice rapidly. There
is also a worldwide retreat of glaciers, the Rockies, Andes, and the Himalayas among many others
are affected. Ocean acidification is also another indicator of climate change, with more than thirty
percent acidification since the industrial revolution (Loarie et al., 2009).
Question 3
Carbon dioxide (CO2) is the foremost gas for trapping heat and is highly accountable for
most of the abnormal warming ...
