Climate Shift
I am confused by my opponents argument. He has taken the Con side and must disagree
and disprove the resolution, but his argument is only in favor of the pro. I must
assume that he is being sarcastic, but I am not sure. Pros Case Point A: Climate shift is real Sub point 1: Scientific consensus "Carbon dioxide and other global
warming pollutants are collecting in the atmosphere like a thickening blanket, trapping
the sun's heat and causing the planet to warm up. Although local temperatures fluctuate
naturally, over the past 50 years the average global temperature has increased at
the fastest rate in recorded history. Scientists say that unless we curb the emissions
that cause climate change, average U.S. temperatures could be 3 to 9 degrees higher
by the end of the century." Scientists are undoubtedly sure that climate shift is
indeed a real threat. As is corroborated by a collection of scholarly articles. 97%
of climate scientists are in agreement.(1)(2)(3)(4)(5)(6)(7) Point B: Climate Shift
is influenced by Humanity Sub point 1: Scientific Consensus "The United States Global
Change Research Program (which includes the Department of Defense, NASA, National Science
Foundation and other government agencies) has said that 'global warming is unequivocal
and primarily human-induced' and that 'climate changes are underway in the United States and are projected to grow.'"(3) "The climate change denial machine has been working hard to discredit the latest UN Intergovernmental
Panel on Climate Change (IPCC) report, which confirms that climate change is occurring and that human activity is primarily responsible."(5) "Ninety-seven
percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities,and
most of the leading scientific organizations worldwide have issued public statements
endorsing this position."(6) Again this is a case of overwhelming scientific consensus.
Sub point 2: Carbon Emissions are a major cause, and a product of humanity "The only
way to explain the pattern [of climate shift] is to include the effect of greenhouse gases (GHGs) emitted by humans."(2)
"Most climate scientists agree the main cause of the current global warming trend is human expansion
of the "greenhouse effect" -- warming that results when the atmosphere traps heat
radiating from Earth toward space. Certain gases in the atmosphere block heat from
escaping. Long-lived gases, remaining semi-permanently in the atmosphere, which do not respond
physically or chemically to changes in temperature are described as "forcing" climate change"(7) Scientists agree that humanity has altered the balance of greenhouse gases on the earth, which is a direct major cause of climate shift. Point C: Climate shift threatens the future, and is therefore a legitimate concern of those who care
about the future of humanity. Global climate change leads to: -Increased temperatures -Changing landscapes -A higher number of droughts,
fires, and floods -Endangered wildlife habitats -Rising sea levels -Greater damage
from extreme storms -More heat-related illness and disease -Economic problems (4)
Sub point 1: Climate shift encourages natural disaster "Hurricanes and other storms are likely to become
stronger."(2) "Anthropogenic warming by the end of the 21st century will likely cause
hurricanes globally to be more intense on average (by 2 to 11% according to model
projections for an IPCC A1B scenario). This change would imply an even larger percentage increase in the destructive potential per storm,
assuming no reduction in storm size."(8) With storms like sandy become more common
and much stronger, Humans living in coastal regions face a very serious threat. Already
hurricanes such as sandy and the recent Typhoon in the Philippines are costing billions
of dollars in damages, and thousands of human lives. (9)(10) Climate shift is likely to cause these storms to become even more intense, therefore threatening
to cost even more lives and money. These death counts and damage costs are not small,
by any stretch of the imagination; with climate shift left unchecked, these counts will grow. Sub point 2: Rising sea levels/flooding
"Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimeters) by
the end of the century, and continued melting at the poles could add between 4 and
8 inches (10 to 20 centimeters)."(2) "Floods and droughts will become more common.
Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent
over the next 50 years."(2) As polar caps warm, ice caps are likely to melt and release
water into the oceans and seas, causing the levels to rise. this could result in flooding
in coastal cities, such as New Orleans, that are close to, at, or below sea level.
Furthermore, climate shift could result in more intense cycles of flooding and drought in other areas
of the world, such as Ethiopia. These are real threats to human lives. Flooding, like
storms, has a very high cost of both money and, more importantly, human life. Sub
point 3: Future effects of climate shift could significantly increase the hostility of the Earth environment. There
are a myriad of effects that climate shift will have that will make the Earth environment, generally, more hostile. "Some
diseases will spread, such as malaria carried by mosquitoes." (2) "Less fresh water
will be available. If the Quelccaya ice cap in Peru continues to melt at its current
rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking
water and electricity without a source of either." (2) "Below are some of the regional
impacts of global change forecast by the IPCC: -North America: Decreasing snowpack in the western mountains;
5-20 percent increase in yields of rain-fed agriculture in some regions; increased
frequency, intensity and duration of heat waves in cities that currently experience
them. -Latin America: Gradual replacement of tropical forest by savannah in eastern
Amazonia; risk of significant biodiversity loss through species extinction in many
tropical areas; significant changes in water availability for human consumption, agriculture
and energy generation. -Europe: Increased risk of inland flash floods; more frequent
coastal flooding and increased erosion from storms and sea level rise; glacial retreat
in mountainous areas; reduced snow cover and winter tourism; extensive species losses;
reductions of crop productivity in southern Europe. -Africa: By 2020, between 75 and
250 million people are projected to be exposed to increased water stress; yields from
rain-fed agriculture could be reduced by up to 50 percent in some regions by 2020;
agricultural production, including access to food, may be severely compromised. -Asia:
Freshwater availability projected to decrease in Central, South, East and Southeast
Asia by the 2050s; coastal areas will be at risk due to increased flooding; death
rate from disease associated with floods and droughts expected to rise in some regions."(11)
Here are some charts to illustrate further effects. (11) Current Effects Future Effects
Summary There is overwhelming evidence to prove that climate shift is indeed real and influenced greatly by humanity. Furthermore, the effects
of climate shift are so massively detrimental that those who are concerned over the future of
humanity ought to care greatly about the massive loss of life, cost of damage, and
other miscellaneous undesirables that are consequences of climate shift. Sources 1. http://www.sciencemag.org... 2. http://environment.nationalgeographic.com...
