Global Warming : Causes, Effects And Remedies

Global warming is one of the most tumultuous topics in today’s society. Some believe it is happening as we speak, while others question its very existence, So, is it real, or is merely a hoax? There is no one answer, but evidence does overwhelmingly support the former. Surely we have all heard this word at one time or another, but few individuals actually know its true definition. Justifiably, however, global warming is not that simply explained. In layman’s terms, it is the dramatic increase in the Earth’s average air and ocean temperature since the 20th century. This increase is primarily attributed to two main culprits: the greenhouse effect and human activity, such as fossil fuel burning. In both cases, carbon dioxide (CO2) is the

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

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).

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.

There has been a rise in average temperature by 1 degrees Fahrenheit over the last 100 years. This rise to due to the human effect on the Earth.

Global warming is drastically changing the world’s climate, causing temperatures and sea levels to rise noticeably. Caused by the usage of greenhouse gases, global warming has brought about extensive controversy concerning its causes and even its existence. Although it is an issue of ongoing concern,many make no modifications in their daily lives. Global warming remains a substantial issue for the world's people, animals and the environment; its ill health effects, forced relocations and the killing off of the food sources combine to make it a widespread problem that requires immediate attention and action.

The Earth's climate has changed throughout history. According to the findings of National Aeronautics and Space Administration (NASA), the change of the earth’s climate has evolved through time. The global sea level rose about eight inches in the last century; the planet's average surface temperature has risen about 2.0 degrees Fahrenheit since the last 19th century; the oceans have absorbed much of this increased heat of 0.302 degrees Fahrenheit since 1969; the increasing number of record high temperature and intense rainfall events since 1950; and the overall increase of ocean acidification by about 30 percent. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. There is no question that increased levels of greenhouse gases cause the Earth to warm in response.

According to Penn State University researcher Michael Mann “ the average global temperature was relatively unchanging in pre-industrial times but sky-rocketed since 1900, and will increase by several degrees more over the next 100 years. There is no convincing empirical evidence that past climate was unchanging, nor that 20th century changes in average global temperature were unusual or unnatural”.

Global warming is and has been known as one of the largest and most challenging problems that pertains to the environment today. Around the world many are experiencing negative impacts on the daily, those from farmers to those living in more forest like environments. As the ecosystem becomes more and more devastated, awareness and prevention of climate change has never been more important. Many people doubt the existence of global warming, however its is clearly evident through the intensification of heat waves and the melting of ice caps.

In the world as we know it, temperatures keep rising every year. The worldwide average temperature has climbed 1.4 degrees Fahrenheit since the year 1880 (). This is due to carbon dioxide (CO2) and other greenhouse gasses in our

It is widely held that climate change is real and happening now Case (2006) as global average temperature has warmed about 0.8°C within the past century. Coupled with this, the past three decades has witness a global average warming of 0.6°C (Hansen et al., 2006). This is largely to due to human induced factors (IPCC, 2001). A recent report produced by the U.S. National Academy of Sciences confirms that the last few decades of the 20th century were in fact the warmest in the past 400 years (National Research Council, 2006). The IPCC also projects that if greenhouse gas emissions, the leading cause of climate change, continue to rise, the mean global temperatures will increase 1.4 – 5.8°C by the end of the 21st century (IPCC, 2001). In a similar

From a scientific point of view, the author describes and substantiates the existence of global warming and also observes the potential effects it could result in. These include of rising sea levels, shifted climate patterns, increased threats to infectious diseases, extreme global temperatures, and coastal erosion. But ultimately, the report informs readers that the degree to which global warming affects life on Earth primarily depends on our decisions.

Multiple scientific studies stated that the global mean temperature has risen 1 to 2 degrees Celsius since pre-industrial periods and claims the climate-warming trends over the past century are extremely likely due to human activities. As a matter of fact, the Earth had gone

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
