The Effects Of Climate Change

Basically climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. Climate change is the greatest threat to nature and humanity in the 21st century and it is happening everywhere. Even today, in many parts of the globe we can see some effects of climate change - melting glaciers, rising sea levels, severe storms, heavy floods, reduced snowfall in the north and a severe drought in the south. Even though the Earth's climate had been fluctuated before in the last 100 years it happens much more often. The average surface temperature has increased by about 0,6-0,7 C. It may seem that it's not too much, but since the climate has become "nonlinear" dynamic system, even small …show more content…
But the most memorable thing that I studied was a theme about global warming. Global warming is a gradual increase in the average annual temperature of Earth's atmosphere and oceans as a result of all sorts of reasons (increasing the concentration of greenhouse gases in the atmosphere, changes in solar or volcanic activity, etc.). Warming, detectable by direct measurements of air temperature is consistent with a wide range of observations made by several independent research groups. Examples of such observations can be sea level rise (caused by thermal expansion of water when heated), melting glaciers, rising ocean heat, humidity increases earlier onset of spring. Raising the temperature of the surface layer of the atmosphere leads to a shift of climatic zones, causing the melting of Arctic and Antarctic ice, and permafrost, leading to rising sea levels. Climate change impacts on the animal kingdom. Many species become extinct, others are changing the traditional habitat. The risk of relocation inhabitants of the tropics to temperate latitudes is that the animals are carriers of tropical diseases such as malaria. In addition, warming may increase the incidence of intestinal diseases, asthma, allergies and respiratory …show more content…
These themes were so different and unique, but one thing connects all presentations – climate change. Most unforgettable were 5 presentation. First presentation was called Indicators and Effects of Climate change by Joel, Amy and Arisa. Basically the largest single indicator of climate change has been global warming that I already described in my previous paragraph. Also, this group was talking about deforestation that means the removal of trees and forests from an area. Deforestation results to the loss of CO2 absorbed in the air as the process of photosynthesis is decreased. Therefore, nature can cause deforestation by Global warming, investigations, etc. Humans can cause deforestation be chopping down trees in certain area for their own uses such as wood, paper, furniture. Then Fazel and his theme of Describing climates showed me different types of climates and their descriptions (North and south polar zones (high latitude and colder zones in the whole world); North and south temperate zones (milt zones); tropical zone (warmer zone; temperature varies throughout the year). Next group, group of Arielle taught us theme of Greenhouse gases and Human Activities. I discovered that 99% of the atmosphere is made up of two gases and they are called nitrogen and oxygen, neither of which absorbs infrared radiation nor contributes to the greenhouse effect. Also, I learnt different types of greenhouse
