The
Science of Climate Change
My name is Digna Colon and on this 3rd
blog I will be responding to a revision of my 2nd blog as an
assignment from my ENG 101 class composition. This revision is based on an
evaluation done by Michael Gomez, a student from ENG 220. Mr. Gomez reviewed my
blog and suggested that my previous blog needed some more information. He
helped me analyzed the major ideas and some of the core issues on my previous
blog have a better and understandable blog for the outside readers. Our class is working on Climate Change and we
are reading the book of The Global Warming Reader
by Bill McKibben. We were assigned to read the chapters “The Anthropocene” by
Paul J. Crutzen and Eugene F. Stoermer, 2000 and “The Scientific Consensus on
Climate Change” by Naomi Oreskes, 2004.
“The Anthropocene”, chapter discuss
how mankind’s activities which could be improved. In addition, he gave me good ideas on how to fix
my work in order to
have significantly grew and how
these activities recognized by Sir Charles Lyell in 1833, and adopted by
Geological Congress and a numbers of scientists have played a huge impact on
climate change. Mankind has expanded in such an amazing way that the Earth
resources are being exploited. For example, throughout the past three century
population has increased tenfold to 6 billion and urbanization has also
increased tenfold having as consequence a draining of the fossil fuel.
Globally this humans growth had led
to the free of SO2 (carbon dioxide), NO (nitric oxide) and CH4 (methane) per
year added to the atmosphere and oil burning causing the rising of temperature
on Earth. According to Crutzen and Stoermer, “thirty to fifty percent of the
land has been transformed by human action”, which clearly means that us human
has oversea the natural reproduction of the Earth to impose our own methods.
For example, “human activities has increased the species extinction rate by
one-thousand to ten-thousand-fold in the tropical rain forest and several
greenhouse gases have substantially increased in the atmosphere”.
Furthermore, humans released toxic substance that reaches
the “ozone hole” that could have damaged a lot of ozone layer. Also mangroves
are being affected by 50% of its loss. These examples clearly illustrate how
the climate deterioration has taken place because of our irresponsible actions.
On the other hand, the chapter “The
Scientific Consensus on Climate Change “which is the report of the
intergovernmental panel on climate change (IPCC) talks about how the media and policy makers
believes that climate is highly unpredictable. Based on this observation,
policy makers and the media have used this as an excuse to prevent any one and
anything from taking stronger measure to stop the greenhouse gas emissions.
IPCC unambiguously that climate is being affected by human activities and that
is modifying the concentration of atmospheric constituents. They also conclude
that the warming of the last fifty years is due to the increased of greenhouse
gas concentration.
Finally, the negative impact
that mankind activities play on climate change will continue to happen because
human growth is a persistent issue that will not stop. In other words, globally
human activities will continue to be a thread to Earth. If a wise plan is not
developed to stop burning fossil fuel, the harm to the environment will continue
and the extinction of animal species or natural disasters like hurricane,
flooding and many others will not be prevented from happening. Having said
this, I believed that human activities on Earth have a major direct impact on
climate change and that we are going to be the direct cause of the destruction of
our own planet.
