The change of temperature in Antarctica due to global warming has had many effects on wildlife and the environment already. Although these effects many not seem big right now, there are many that will progress and continue to change Antarctica’s environment, depending on how the temperature changes. Temperatures have been rising constantly in Antarctica. Last April was the second warmest April in history, only behind the year before that (Waldman). The whole world is experiencing global
It is easy to observe that the effect of global climate change on the Earth. For example, the rises of sea levels, glaciers, and polar ice caps are melting; numerous animals are emigrating to find other places to exist; trees are in bloom sooner. Scientists have confirmed that the temperature will keep on rising up for the next decades because of human activities in the industry (Alina). One of the biggest problems facing us now is global warming. It not only affects animals and plants but also the human population, which is indeed scary (Markham).
These individual events obviously are not concrete proof, but they contribute to a larger pattern (Nye and Powell 19-33). Generally, Earth’s climate changes slowly at its own pace (Nkemdirim566+). The CO2 levels in the atmosphere have increased dramatically since the industrial age, and that is part of the problem. The rate humans add to the carbon levels is causing the greenhouse effect to get stronger and stronger. The greenhouse effect is closely associated to global warming.
Prior to the industrial revolution, non-anthropogenic variables were leading roles in climate change but has quickly changed as anthropogenic activities play the leading role in climate change today. Although climate has been changing for decades it has been a recent change in causes that allows climate change to worsen as time goes by. Climate is the average that stands consistent for a long time in an area of precipitation, temperature, atmospheric circulation and atmospheric chemistry. Climate can be affected and changed by man forced and unforced factors. These include volcanic forcing, solar forcing, solar variability and the industrial chemicals.
There are three impacts in the Climate change which are the following below: 1. Coastal areas ground loss (67%) 2. Water resources concentration of rainfall in winter water quality degradation Increased need for irrigation 3. Agriculture Increased need for water increased weeds, pests and diseases shift of farmland to North The Impacts of Climate Change: • Forests and biodiversity • Decreased productivity • Increased risk of fire • Migration and extinction of forest key species • Increase of diseases • Extinction of plant and animal species • Increased risk of exotic species
Of course, land and ocean temperature is not the only way to measure the effects of climate change. A warming world also has the potential to change rainfall and snow patterns, increase droughts and severe storms, reduce lake ice cover, melt glaciers, increase sea levels, and change plant and animal behavior http://news.discovery.com/earth/global-warming/10-signs-climate-change-is-already-happening-130422.htm http://news.bbc.co.uk/2/hi/in_depth/629/629/6528979.stm#arctic Some of the Key statistics / noticeable changes can be given as follows: 1) The rate of warming is unprecedented in atleast 11,000 years 2) The hottest decade on record keeps on changing : global mean temperatures have increased by approximately 1.33 degrees Fahrenheit (0.74 degrees Celsius) over the past century 3) Arctic Sea ice is in a “Death Spiral” : The extent of summer sea ice covering the Arctic Ocean is now decreasing by a rate of about 13 percent per decade, compared to the 1979-2000 average 4) On average, since 1993, the sea has been rising by 3.18 mm per year, primarily as a consequence of thermal expansion due to warming, and to the melting of ice
The Arctic Ocean has been cold for two million years. The Arctic is consequently far from uniform (Callaghan et al., 2013). The polar bear (Ursus Maritimus) has a stocky body, it lacks shoulder humps and it has a longer neck in comparison to other areas of the body. Polar bears have a remarkable ability to store vast amounts of fat during periods where prey is unavailable (Stirling, 2009). They feed mainly on marine mammals.
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. It may refer to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions. That is the notion of climate change. Theory is that. But do we have any evidence that proves the occurrence of climate change?
The global climate change and its consequences are leaving a bad impact on the countries to face poverty and hotter temperatures. Climate change impacts include temperature rise, greenhouse and carbon dioxide gas emissions, erratic rainfall, salinity intrusion, the rise of floods, cyclones, storm surges and draught, ice sheets melting which will seriously affect the agriculture, and the world. Researchers agree that climate change is a fact.Temperatures have been increasing
The rapid rise in greenhouse gases is a problem because it is changing the climate faster than some living things may be able to adapt. Also, a new and more unpredictable climate poses unique challenges to all life. Historically, Earth's climate has regularly shifted back and forth between temperatures like those we see today and temperatures cold enough that large sheets of ice covered much of North America and Europe. The difference between average global temperatures today and during those ice ages is only about 5 degrees Celsius (9 degrees Fahrenheit), and these swings happen slowly, over hundreds of thousands of years. Now, with concentrations of greenhouse gases rising, Earth's remaining ice sheets (such as Greenland and Antarctica) are starting to melt too.
