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
The absorption of solar radiation leads to an increase in temperature. The trend on the graph shows a decrease of ice in the Arctic. The melting of Arctic ice is an example of a positive feedback.
Climate Change, everyone has probably heard about it in the news or on the web, but what does it really mean and what causes Climate Change to happen? Earth has always cooled and heated itself by rotating around the sun but, scientist found that earth temperature has risen throughout the years, there are many causes of this change in temperature, and the question is who should we blame for this. In my opinion humans are the primary cause of Climate Change because we have incremented the gases in the earth atmosphere, cut down hectares of trees with little to no reforestation of them and caused many accidents that affect the tree population. The first reason why I believe that humans are the primary cause of climate change is
According, to the Sanford Solar Center(SSC), The average global temperatures will increase by 2.5-10.4º F by the end of the 21st century. Sounds like no big deal rigt but SSC stated "The difference between global temperatures during an Ice Age and an ice-free period is only about 5ºC." Because of our actions will result in more hot days, which leads to Warmer ocean water, changes in precipitation, intense and frequent tropical storms and hurricanes and other weather patterns. Warmer climates causes sea levels to increase. The next century, melting glaciers and expanding seawater will affect wildlife that cannot survive in hotter environments. They may become extinct.
According to the Intergovernmental Panel on climate change in (2001), the burning of fossil fuels and other human and natural activities has released enormous amounts of heat-trapping gases into the atmosphere. This mean, these emissions have caused the Earth's surface temperature to rise, and the oceans absorb about 80 percent of this additional heat. However, some scientists opposed the statement that human activities are reason behind the observable fact of sea level rise, According to William M. Gray, “natural variations are the cause of periodic global temperature increases and human kind has nothing to do with the temperature changed”. That shows, the changes in natural phenomena such as solar radiation produced most of warming and had a small cooling effect afterward. Despite that, Subsidence in Venice is caused by both natural and manmade factors.
Here is a simple definition of global warming. And yes it 's truly irruption. Over the past 50 years the mean global temperature has raised at the quickest rate in recorded history. Experts see the tendency is quicken, All but one of the 16 hottest years in NASA 134-year record have engaged since 2000.Climate change disputants have represented that there has been a “delay” or a “retardation” in rising global temperature but various recent studies having 2015 paper published in the journal Science have rebutted this contend.
However, volcanic eruptions can also impact the atmosphere of earth. When volcanoes erupt, they expose the earth to a wide range of gases and particles that could possible affect the earth’s surface and its climate. “Some of the particles that are released from volcanoes cool the planet by shading the incoming solar radiation” (Centre For Science Education, 2012). Small ash particles generate a heavy and dark cloud in the troposphere, which is the cause of the cooling in the atmosphere. Most of the particles within this dark cloud will fall out of the atmosphere and convert into rain within a few hours.
Climate change is an adjustment of global weather and atmospheric conditions and its effects on all other areas of life. Scientists have known that the conditions on earth have a tendency to change over the past 650,000 years, however, not only are we experiencing a rate of change greater than ever before, it is also 95% likely that human activities are the origin of the problem. Scientists can gather evidence about past climates and the planet’s responses from ice cores, tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. From this information, it is calculated that current warming conditions are occurring approximately 10 times faster than ever. This fluctuation in temperatures has caused surface temperatures to rise, ice sheets to shrink, ocean levels to rise, and ocean acidification.
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.”
These problems are not going to fix themselves without help the plant will warm up 0.6 celsius without any greenhouse gases influence. According to meteorologists from 1890 to 1990 temperatures have risen 0.72 degrees fahrenheit to 1.26 degrees fahrenheit. In fact through the 20th century global temperatures have rises 1.4 degrees fahrenheit which could lead to surface temperatures increasing. There has been efforts to help with global warming considering from 1998 to 2009 $99 billion dollars have been spent on climate change.
Climate change is more serious than we take it. If it continues, everyone will parish. Climate change affects us in many different ways. It causes animal population numbers to decrease, slows down transportation to the north, and causes flooding and the rise of the sea level. Global warming exists, and it is not only affecting the environment.
