The two graphs illustrate the relationship between the changes in atmospheric/global temperature with time (in years) when various natural and anthropogenic climatic factors are in existence. Both graphs show sharp, but fluctuating, observed temperature records in every span of five years, between 1900 and 1920. The observed temperature anomaly is recorded as -0.3oC after every five years for the entire 20 years. The observed temperature variance is seen to have a rising trend from 1920 up to 1945 after which there is a slight decrease in temperature up to 1960. The recorded temperature anomaly then continues to rise until it reaches a peak of 0.95oC. On the other hand, the line graphs of the climatic temperature models are smooth and depict a steady rise in temperature anomaly from 1900 up to 1960. In the first graph, which depicts natural and anthropogenic forcing, there is a sudden decrease in temperature anomaly of the models followed by a cumulative increase until the point where it reaches a peak value of 0.74oC. However, in the second graph, which involves natural climate for...
In his piece on climate change, Richard Lindzen addresses his stance on the heated debate of global warming. He claims that there is, in fact, no ongoing catastrophic temperature increase. Lindzen, a Professor of Meteorology at the Massachusetts Institute of Technology and a recipient of the Jule Charney award from the American Meteorological Society (Richard Lindzen), believes that the earth goes through natural phases of warming and cooling. In this piece, he examines why he believes people have a false conception of Earth’s climate shifts.
Global temperatures have noticeably been rising since the mid 1800’s.The average temperature has increased by 0.6 ± 0.2°C since 1860 according to (John Sweeney, 2003)with accelerated warming apparent in the latter decades of the 20th century. The legitimacy of global warming had long been debated, however in a report by (IPCC, 2007) it states that warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level. Simulations on models such as EC-Earth provide us with predictions for future climate change. Depending on levels of emissions an increase of 1 to 5.5 degrees celsius is expected in average global temperatures by 2100.
Hong Kong nowadays has a major problem on global warming due to climate change. Climate problems may not take up any awareness among people in today’s society. Humans are responsible for many of the climate problems we are facing. Climate changes naturally and the current trend of global warming started before the industrial revolution. Before the climate change the climate was a lot warmer. Weather and temperature could be one of the major issues that affects global warming and climate change.
For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.
Furthermore, this analysis must take place amidst serious gaps in the existing research and technology concerning the developing climatic conditions. For these reasons, global warming stands as one of the most daunting policy issues facing our world today. This is compounded by the debate over the very existence of climate change. While countless sources of empirical evidence testify to the very real presence of climate change the world over, considerable denial of the phenomenon still exists. The argument has been made that evidence of climate change is a gross overstatement, or in some cases, a complete fabrication.
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
Because the Earth is slowly warming up, heat waves, for example, have been occurring more frequently and for longer durations. According to the Climate Communications, “In 2010, 19 countries set new all-time record high temperatures, but not a single country set a new all-time record…” (Overview). Comparing this to Gore’s speech, eighteen countries have experienced all new highs in heat since the European heat wave in 2003. This increase in temperature is due to the shifting of the climates in specific regions as an after effect of global warming.
Our world is always changing, so is our climate. Some changes are apparent, others not so much. Climate change is an important issue of concern in the twenty-first century. Environment, if it changes at all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly all scientists predicted that it would take thousands of years for the planet to warm up due to emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years, things began to change. The rate and the amount of warming that is happening on this planet are unprecedented. Wearth says, “People did not grasp the prodigious fact that both population and industrialization were exploding in a pattern of exponential

There is no longer any question that our world climate has changed (King, 2004). Over the last 100 years, "temperatures have risen by about 0.6 degrees Celsius and global sea level has risen by about 20cm" (K...
The debate on the issue of Global Warming is fiery hot. There are many skeptics who do not believe in the existence of Global Warming. However, there is validity in the theory that Global Warming is real. The fact is that Global Warming is real and it is here. There is more than enough evidence to assure the existence and the disastrous effects of Global Warming. The Earth and its inhabitants continue to suffer the consequences every day. There are critics which try their hardest to deny the fact that Global Warming is a true issue to be concerned about. However, those skeptics are going to feel the heat eventually, for they are playing with fire.
What happens when too much carbon dioxide gets omitted into the Earth’s atmosphere? The condition known as Global Warming occurs. Global Warming is the rising of the Earth’s surface temperature due to chemicals in the atmosphere. Global Warming has many threats on the climate and even the health of the people on this planet. Some of these threats include the altering of crop seasons and even effect the way organisms survive on the planet. The first thing I think I should discuss when talking about global warming is what causes it to occur.
While critical of global warming alarmism, this documentary does not doubt that the earth is warming. Instead, they claim that scientific evidence demonstrates that such warming is but a natural variation in earth’s climatic history, similar to the Medieval Warm Period of the Little Ice Age. The documentary uses several lines of evidence to back up this claim, including ice core data that they claim when rightly interpreted shows carbon dioxide as having a lag time when earth’s climate has warmed in the recent and distant past, making it doubtful that it could be responsible for the increase in temperature that has been observed recently. The timing of the recent warming, which was most pronounced in the late Nineteenth Century through World War II, stopped and reversed to a cooling trend in the mid-Twentieth Century, and then rapidly warmed again in the past three decades, is dissected. Since this warming began before the advent of major human sources of greenhouse gas emissions and the period of most dramatic industrial...
“The temperatures on this planet have always fluctuated naturally on this planet. Looking back over the past 100 years, the earth warmed from 1900 to around 1940. There was global cooling after that until the late 1970’s.” (Scherer 20) The people who say this do not understand that there are weather patterns, but the pattern that is going on now...
The United States releases twenty tons of carbon monoxide per person per year. Carbon Monoxide release is a result of burning fossil fuels with an insufficient amount of oxygen that causes the formation of carbon monoxide that pollutes our environment. Every day fuel is burnt by cars, airplanes, large factories and manufacturing plants. This is causing a very large and deadly problem for our environment. When gases used on earth are released into the atmosphere they act as a blanket and trap radiation that is then redirected to earth. This concept is called the Greenhouse Effect. In this essay I will discuss the greenhouse gasses and their role in global warming.
