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
An increase in temperature and rainfall also lead to the change in sea temperature and sea levels. Jennifer (2006) notes that, ‘Sea surface temperatures in many tropical regions have increased by almost 1°C over the past 100 years (some tropical seas up to 2°C) and are currently increasing ~1–2°C per century. In the Great Barrier Reef, sea surface temperatures have increased 0.46°C per century in the north to 2.59°C per century in the waters off Townsville. Sea surface temperatures on the Great Barrier Reef in early 1998 were the warmest in the past 95 years of instrumental record and were associated with significant coral bleaching.’ The annual sea temperature is rising and it will result in many wild animals died in the Great Barrier Reef. The average sea level has risen by approximately 8 centimeters per decade.
The first thing and also the most significant thing is that the planet is warming. Over the last century, the planets temperature has risen by around 0.6 of a degree celsius. Carbon pollution has driven up the global average temperature for more than a century. So perhaps it’s no surprise that the 10 hottest years ever recorded have all occurred since 1998. The hottest year on record is 2016.
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 one of the most severe environmental challenges facing the world at present. It refers to any change in climate over time, whether due to natural variability or as a result of human activity (Kinyangi et al., 2009). Global warming shows increasing trend and is expected to bring about long term changes in weather conditions (FAO, 2008). Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen.
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.
WHAT ARE THE IMPACTS OF CLIMATE CHANGE THAT AFFECT THE EARTH NOW AND FUTURE? What is climate change and what does it do? I am going to talk about climate change and the effect it is harming on earth. So what is climate change? Climate change is a change in global or regional weather in a long period of time.
However, the impacts of human activities have led to abnormal fluctuations of these parameters against the background values. Some of the prominent evidence of climate change includes the increase of global mean surface air temperatures over the land and oceans, the remarkable increase of atmospheric CO2 concentrations globally and ocean acidification. In this report, the mitigation
Oceans rising, temperatures vary, record level floods, historic droughts, tsunamis, and devastating hurricanes; BOOM! The Earth has gone wild. Scientific evidence suggests that these changes are due to climate change. Climate change is an alteration in the usual temperatures, and weather of a region. The signs that climate change affects our one and only earth clearly show up in the oceans and atmosphere.
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.
The overall increase in sea surface temperatures has occurred during the past three decades. The rate of increase in sea level has increased to more than an inch per decade in recent years. An increase in atmospheric carbon dioxide levels, which dissolve in water, have lead to an increase in ocean acidity (United States Environmental Protection Agency, 2015). In the Great Lakes, lake ice form later than expected because warmer sea surface temperatures in the Great Lakes have contributed to a decrease in sea level by increasing rates of evaporation. This extends the season for evaporation (United States Environmental Protection Agency, 2015).
If we noticed it or not, our planet is warming up. All the way from North Pole to South Pole. Since 1906, the global average surface temperature has gone up from 1.1 to 1.6 degrees Fahrenheit, this is more noticeable in the polar regions. This effects of the rising temperatures isn’t to be taken lightly just because the average surface temperature has gone up by .5. The small change in heat is melting the glaciers, not just the north and south poles but mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
