Global Warming and Human Population

Deforestation occurs primarily as a result of agriculture, fuel use and production, firewood, charcoal, timber harvesting, pasture-clearing for livestock animals, and expanding human settlements. When deforestation happens to a country that you live in it can have a huge impact, "These deforested areas almost always end up as wastelands via the processes of soil erosion and desertification, if they aren’t reforested. Many of the areas of the world that were deforested thousands of years ago remain as severely degraded wastelands or deserts today." Currently, the world’s annual rate of deforestation is estimated to be about 13.7 million hectares a year, which is roughly equal to the total land of Greece. Half of the areas deforested gets reforested to some degree, but these new-growth forests don’t function in the same ways, support the same biodiversity, nor do they provide the many benefits that old-growth forests do cause many societies to eventually collapse if they cannot come up with a better

Climate change is evident throughout the world and is a major issue. It is no secret that our planet is getting warmer. Global warming is now recognized in the scientific community as a real problem. There are multiple aspects that are causing this issue. Majority of the warming is caused by greenhouse gases. Volcanic eruptions and changes in the intensity of solar radiation have offset the warming partially. It is estimated that average annual temperatures will increase 3.5°F-9.5°F by the century’s end.

Scientists have documented the rise in average temperatures worldwide since the late 1800s. Earth 's average temperature has risen by 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past century, per

The greenhouse effect, warming that occurs whenever the atmosphere traps heat from Earth towards space, is the main cause of global warming (NASA, 2016). Gases such as water vapor, nitrous oxide, carbon dioxide, and methane do not respond chemically to drastic changes in temperature, force climate change. One of the reasons for this is because of the deforestation of land for agriculture or industrial needs has increased concentration of green house gases.

In the past 130 years, the average temperature increased by 1.5 degrees Fahrenheit, with more than half of its increased in the past 35 years.( Science for a healthy planet and safe world). In 2001 to 2010 it was the warmest decade since 1880. However this was the year when enough temperature records became able to calculate a global average. However it shows that average global temperature are likely to increase by 3.1 to 7.2 degrees Fahrenheit by end of the century depending on how much carbon is released.( Climate hot map). In the past 40 years it has been the warmer than average. The hottest year recorded. The other 12 hottest years recorded have all occurred since1998. ( Science for a healthy planet and safe world).

The authors describes that greatly increasing Carbon dioxide gas in the earth atmosphere bring about rising of earth temperature. A greenhouse gas, Carbon Dioxide, is an unaware emission product of human activities such as industrial, transportation, and human facilities. Scientist wisely claim that only 1.5 degrees Fahrenheit rising have made change in weather patterns and sea water level in this century. The earth temperature rising come up with many plants and animals die out. Moreover, dropped agriculture products effect 1 percent global economic losses.

The Earth’s temperature has been rising over the years. Sail Bhattacharya a professor & head of a medical college claims that over the last 8000 years, Earth’s surface temperature raised by 1 degree Celsius only (1). He also said, at the present rate of global temperature would rise by 2.5 degrees Celsius by 2050” (1). It’s a fact that the earth has gotten warmer over the years. At this moment the temperature hasn't raised much, only 1 degree Celsius. It may seem like it’s not a big deal, but it actually is, because the rising temperature rate is increasing as time passes according to Sail Bhattacharya (1). The temperature rising might not cause much harm now, but can badly affect us or whoever is living on Earth in the future.

Help Save the Climate website declares that there are now strong evidences of a rapidly warming world. The Third Assessment Report (TAR) of the Intergovernmental Panel on Climate Change (IPCC) contains most of the following. Firstly, the surface thermometer record presents that historical temperature records increased 0.4-0.8°C in the last 100 years (IPCC, 2001). Figure 1 shows the abnormal temperature from 1856 to 2005 comparing with global average surface (horizontal line). It could be observed that global average surface temperature has slightly increased since 1862. And the increase has been enlarged to 0.6 ± 0.2oC when entered 20th century. Help Save the Climate claims 1990s were the warmest decade since records began. This data set clearly reflects the temperature trend based on directly measured temperature, which might has less room for error and no doubt of methodology comparing with more complex means. Natural Resource Defence Council (NRDC) also indicates average global temperature has increased at the fastest rate over past 50 years. Figure 3 obviously shows that we are experiencing an extremely warm period on earth comparing with past 1000 years.

Agricultural expansion such as cropland is a leading cause of deforestation. Plantation expansion for logging is another leading cause of deforestation. Infrastructure building including road construction is a huge cause of deforestation. All of these causes lead to the effect of

Over the past one hundred years, global warming and climate change has triggered a temperature increase of 0.74 degrees Celsius globally. To put that in perspective, 0.74 degrees Celsius is equal to about 1.33 degrees Fahrenheit. It is expected that over the next hundred years, the temperature will rise another 1.8 to 4 degrees Celsius, or a shocking 35 to 39 degrees Fahrenheit (Wiederholt and Post). This means that over 200 years, the global temperature will have risen by almost 50 degrees Fahrenheit; a truly shocking statistic. The immense rise in temperature has, and will continue to affect all forms of life, especially primates.

Over the last decade Earth has seen some of the hottest years in history. This is due

From the 1880s to the 2000s, temperature has had a mean increase of only 1.5 degrees Fahrenheit. For example, the 2000s show the warmest average temperature, but decades prior show there has been fluctuations and not a constant rise in temperatures globally. “If the current rate of increase continues, the world will warm by [3.6 degrees Fahrenheit] in the next century,” (Osborn). With this information and all of the averages of temperature, we can predict that it will take at least 3 centuries before the world will heat even 10 degrees Fahrenheit. This is not significant enough to worry about at the moment. Yes, in future generations, it will be a concern, but while we are here, it is not.

There are many causes/factors to deforestation, which are largely associated with direct human influence. The first proximate cause to deforestation is infrastructure expansion (Geist & Lambin, 2002, p. 144). This refers to transportation (roads), private and public markets, rural and urban settlements, and private and public services (water lines, oil exploitation, etc…) (Geist & Lambin, 2002, p. 144). The next cause is agricultural expansion, which includes, large or small-scale cultivations, shifting cultivations (slash and burn), and, of course, cattle ranching. Wood extractions for industrial and domestic purposes are other proximate causes to this issue.

For over a hundred years, scientists have been carefully gathering and verifying data on the earth's temperature. The latest data reveals some striking trends:All 10 of the warmest years on record have occurred in the last 15 years The 1990's have already been warmer than the 1980's- the warmest decade on record The global average surface temperature has risen 0.5 degrees (site source)For the first time ever, the Intergovernmental Panel on Climate Change, the authoritative international body charged with studying this issue, concluded that the observed increase in global average temperature over the last century "is

Deforestation is a problem that does not concern many people, but it is an issue that the people of Earth need to deal with. In the past 50 years deforestation has increased a significant amount, but people around the world have been removing the forests since the 1600s. The forests remaining are in danger as the human population goes up, the need for resources will also increase and this will make the deforestation of the last forests come quicker before humans realize it is too late. Unless the people address this threat to the world, it will be too late because this is something that can be fixed, the forests can be rebuilt but it has to start right now before there is nothing people can do. There are many causes for deforestation such as, clearing space for urbanization, making areas available for houses, or harvesting the lumber for goods and other consumer items and all of these have an effect on the world. The consequences of deforestation can affect all aspects of life on Earth, including the water cycle, the soil, and the life quality of species around the world.
