A lot of people living on the coast will be forced to move and relocate, which can create a lot of problems. Most predictions say that the sea level will continue to rise, and will probably accelerate. A recent study shows that sea levels could rise 1-2 meters by 2100, which is enough to nearly flood the whole of Bangladesh, a country of 156 million people. and if the whole Greenland ice sheet melts, sea levels will rise
According to, (http://www.nytimes.com/ by Justin Gills), “As of October 2015, the Earth had warmed by about 1.7 degrees Fahrenheit since the year 1880, when it is recorded at a global scale”. The number seems to be low, but as an average over the surface of an entire planet, it is actually high. This explains why much of the world’s land ice at the North pole is starting to melt and the oceans are rising at an accelerating pace. The future generations are indeed in a big trouble if this phenomenon is to happen in a long run. In a longer term, if the emission of greenhouse gases are to be worsen, the risks are profound that Scientists fear climate effects so severe that could cause to extinction of plants and animals, and melt the polar ice caps, causing the seas to rise high enough to flood most of the world’s coastal
This fluctuation in temperatures has caused surface temperatures to rise, ice sheets to shrink, ocean levels to rise, and ocean acidification. In the past few years, there have been more extreme record events than seen before, such as larger and more powerful storms, longer and hotter droughts, et cetera (Climate Change). Everything in our world is so finely tuned that just a few degrees means the difference between 30,000 feet of ice, and extreme droughts and heat waves (The
Climate change is a change in global or regional weather in a long period of time. I believe the climate change is the biggest problem because it has done lots terrible impacts to the earth. Now the global warming is happening. From the 1900 to 2000 the global temperature has increased about 0.54 Celsius degrees and it is causing the melting of ice in North Pole and South Pole. Then the chain reaction is beginning.
The signs that climate change affects our one and only earth clearly show up in the oceans and atmosphere. A place where climate change is most notable is in the sea levels. Over the past years sea level has risen so much that it has caused damage to ecosystems. “Sea level rise is caused primarily by two factors, related to global warming: the added water from melting ice sheets and glaciers and the expansion of sea water as it warms”(Understanding, 2016). This is concerning because the areas living near or below sea level can one day, in the near future, be underwater.
The global average temperature increased by about 0.8°C from 2005, but the current warming trend is 0.13 – 0.16 °C per decade, and it is projected to continue to rise at a rapid rate (Hansen et al.2010). The effect of the activities of man especially in technologically advanced nations, has brought about emission of CO2 and other greenhouse gases which has resulted in the depletion of the ozone layer and global warming (Hegerl et al., 1997; Tett et al., 1999, 2002; Stott et al., 2000).These can be seen from the changes in meteorological parameters such as temperature and precipitation.
In California climate change brought with it higher temperatures than ever before. California faced record-breaking heat in June as valleys faced over a hundred degrees. But the temperatures are not what scares me, it is what happens because of the temperature. The shortage of water is a known problem within California. But with the escalating heat, the little water we have left won’t be able to last long.
The next century, melting glaciers and expanding seawater will affect wildlife that cannot survive in hotter environments. They may become extinct. Finally, our health is in danger as well, as the Climate Changes could result in the spreading of certain diseases such as malaria. Because if you have ever live in a hot or humid climate you have alot of mosquito's. Specially with all the flooding of major cities on coast line because of the rising sea levels, a greater risk for individuals to become heat casualties , and the air quality will be thick and may not be that good
Climate change refers to the long-term change in the earth’s climate due to the increasing average global temperature which is so-called global warming. It is estimated that climate change results in 600000 deaths worldwide every year, 95% of them occurs in the developing countries ( Conserve-Energy-Future, 2013). As catastrophic impact has been substantially created due to climate change, determining the leading causes to this phenomenon becomes a burning issue globally. Although some people suppose natural factors are to blame for negative alterations to the climate, I hold a strong belief that anthropogenic activities through industrialization and agriculture development are the dominant drivers of climate change. First and most importantly,
Throughout the course of history the earth’s climate has dramatically, changed within the last 650,000 years, there has been seven cycles of glacial advance and retreat. “In the past two decades, the scientific community has reached an overwhelming consensus those human activities are causing changes to the global climate.” (David B. Resnik). There has been a massive increase production of carbon dioxide, methane, and other greenhouse gases in the last century that has caused the climate change around the world. “If humanity does not start significantly reducing greenhouse gas emissions, average global temperatures will likely increase by several degrees Celsius in the next fifty years, which would lead disastrous environmental consequences, such as flooding of coastal areas, increased numbers of powerful hurricanes, desertification, decreased agricultural productivity, and loss of biodiversity.” (David B. Resnik). The main driver of today’s warming is the combustion of fossil fuels.
Consequences include loss of coastal wetlands and barrier islands, and a greater risk of flooding in coastal communities. Low-lying areas, such as the coastal region along the Gulf of Mexico and estuaries like the Chesapeake Bay, are especially vulnerable. Global sea level has already risen by 4 to 8 inches in the past century, and the pace of sea level rise appears to be accelerating. The Intergovernmental Panel on Climate Change predicts that sea levels could rise 10 to 23 inches by 2100, but in recent years sea levels have been rising faster than the upper end of the range predicted. The Arctic sea ice extent set an all-time record low in September 2007, with almost half a million square miles less ice than the previous record set in September 2005, according to the National Snow and Ice Data Center.
Throughout history Earth`s climate has changed a lot, and there is a lot of evidence that shows how humans have contributed to this changed and effected the Earth. Just in the last 650,000 years there have been seven cycles of glacial advances, the increase in the thickness and area of a glacier. As well as glacial retreats, a condition occurring when backward melting at the front of a glacier takes place at a rate exceeding forward motion. Most climate changes are attributed to very small variations in the earth`s orbit, that change the amount of solar energy our planet receives. The 21st century has seen the most temperature records broken in recorded history.
Climate change will affect communities in the north by destroying the best way to transport things. Finally, the sea level rise and flooding is a big problem people-wise. Flooding causes millions in damage that sometimes cannot be reversed. Flooding is encouraged by climate change because of the increase in moisture trapped in the air, and rain happening earlier in the year and falling on still frozen ground. Houses being destroyed by increased water also leave people homeless and cost a lot to fix.
Therefore these effects could be substantial. Scientists believe that the destruction of trees is a adding reason to the cause of global warming. Also the IPCC has estimated that if the climate rises 1.5 degrees celsius to 2.5 degrees celsius that 20% to 30% of plants would have high risks of extinction. The same would go for animals if the temperature continue to increase the same percentages of animals could face extinction as well. Now in the last 50 years heat waves, droughts, and flood have all increased.
The continuing loss of the Arctic ice has been a prime example of the effects of global warming happening. Overall through the 1970’s to the present there has been an overall 40% decrease in the Arctic ice (Singh 5). A study was conducted from the 1970’s to 2014 to determine actually how much in numbers we have lost from past to present, and the numbers prove to show negative effects that have allowed for more loss of the ice. Scientists have said that during the 1970’s, the average amount of sea ice in the Arctic was 8 million kilometers, compared to the Summer of 2012 which left the sea to less than 3.5 million kilometers of ice (Singh 3). The 2012 findings have shown that the amount of sea ice in the Arctic has shrunk to the smallest amount
