Andrew Bolt's Analysis

As a result, it is no surprise scientists have estimated that in the last two hundred years the global temperature has risen by 1.4 degrees Fahrenheit. Maybe that does not sound like much, but consider this: it only took four degrees to bring us out of the last Ice Age. Experts agree that global warming is one of the greatest—if not the greatest—challenge facing all of humanity.

Fred Singer uses data specifically from the past 10 years to support his claim that global warming isn’t real or temperature is not rising, representing a biased sample. The data from the past 10 years are used selectively to tailor his arguments. One could pick any end points in the climate change data and find a cooling trend but if you were to look at the overall data, the temperature continues to rise at an exponential rate. Fred Singers argument uses a specific interpretation of data to appeal to the reasoning side of the public. A potentially better argument could be, cooling trends can be plotted at any end points on the temperature data, but the long term data shows an exponential growth in temperature.

What is the overall tend observed in global temperatures over the past thirty years or so? What is the projected trend over the next few decades (if

Climate change is a serious issue, or is it? Since the late 1990’s the temperature rose dramatically, but surprisingly since 1998 the average temperature only raised a little. (why climate change is taking a break) This is because of increase of Greenhouse gasses, and carbon.These are natural gasses, in many ways science proves Global Warming is a natural problem that overtime will figure itself out. The famous El Nino’s are a good example of this, in 1998 there was a very strong El Nino, and the temperature went back down. I and many scientist think Global Warming is natural and here's why.

In present day, the ocean is warmer now than it has been in the past 50 years. In the article, " Signs of Climate Change", it says that in 1960 the average ocean tempature change was -.3 degrees but in 2010 the average tempature change in the ocean was .6 degrees. Where I live the tempature is still continuing to rise more and more each year. With warmer ocean tempature comes rising sea level. In present day the sea level has rose by 7 inches in the past 100 years. In 2100 th tempature is around 15 inches higher than it is in present day. Both of these things are causing more tropical storms to happen and is also making the beach less and less

According to the IPCC (2013) observed changes in the global climate system have been warming since the 1950s and many of those changes over decades to millennia have never

The temperatures have increased 33.53 0F from 1880 to 2012. If we see from 1850 to 1900, there is flat line, so the rate of change has been constant. From 1910 to 2000, there is a steeper line, so the rate of change in average global temperature has increased. All these trends imply that the global temperatures will keep increasing over time.

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

Though scientific evidence has been found to have its flaws, there is still a substantive basis for sizable global warming due to the man-made greenhouse gas emissions that cannot be disputed.

According to a study in October 2015, “Earth had warmed by about 1.7 degrees Fahrenheit since 1880 when records begin at a global scale. Which includes the surface of the ocean. The warming is greater over land and greater still in the Arctic and parts of Antarctica” (Gillis, 2015). Although an increase of warmth of 1.7 degrees doesn’t seem like it’s a big deal,

A second study states “Although some records are available from the 1600s and 1700s , systematic measurements of climate began in the mid-1800s. The data include measurements of surface temperature over land and the oceans, precipitation amounts, sea-ice extents, and global sea levels. Since the 1970s, satellite studies have provided additional data on temperature trends at Earth’s surface and through the layers of the atmosphere” (“Global Warming- Britannica”). The second source backs up the first source with exact quantitative data about changes in the first. (See pictures on page 6-7 ). The first topic of the United Nation’s Climate Change 2014 Synthesis Report is “Observed Changes and their Cause” which states “Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850” (“United Nations” pg 7). These three sources prove, through scientific observational facts, that the climate of the Earth’s surface is changing very rapidly, therefore, proving that through conclusive science the topic of climate changer is accurate.

We are slowly destroying our climate and environment. The land and ocean surfaces have warmed roughly 1.53 degrees Fahrenheit from 1880-2012 (How much has the global temperature risen since 1880? 1). Land warms faster than the oceans. In the northern hemisphere, 1983 to 2012 were the warmest 30 year period in the last 1,300 years (How much has the global temperature risen since 1880? 1). This is a cause for concern among scientist.

So, is the temperature really rising? This simple answer to this question is “Yes.” According to Watson, we now have strong evidences that the climate is changing and that human activities were the primary cause of the changes during the 20th century (24). He asserts that the temperature increase in the 20th century was greater than that for any other century during the last 1000 years and the temperatures now are warmer than at any time during this period (26). Johns acclaim that the rise in CO2 levels from 280 parts per million around 1700s to 380 p.m. Today is the major factor

However, CEI scientists have reported that there is no proof that rising temperatures are linked to global warming. The Earth has gone through various periods of cooling and warming throughout its history. The rising temperatures are simply the Earth warming itself up from the previous ice age (Competitive Enterprise Institute). Contrasting with the virtual world of computer simulations, the real world presents a very different picture. The EPA (Environmental Protection Agency) website even states that:

“When taking the heating of the entire climate system into account, our planet has warmed at a rate equivalent to 4 Hiroshima atomic bomb detonations per second over the past 15 years” (Cook). Our planet is becoming warmer. When scientists add up all the heat warming the land, oceans, atmosphere, ice melting, earth is accumulating heat equivalent to four Hiroshima bombs worth of heat per second. Global warming is a serious issue faced by our world as there has been a significant increase in temperature over the years. But the article published by Dr. Mark Sircus on “Global Warming -largest science scandal in the history” refutes the theory of global warming. Dr. Sircus states that there is no linkage between carbon dioxide and temperature leading to global warming, the sea level is not rising, arctic sea ice extent is now higher and climate change is due to solar activity. Dr. Sircus also points out that that the recent weather changes are not in line with global warming and “we are in the beginning of a deep freeze” (Global Warming - Largest Science Scandal in US History). NASA and the scientific community states that global warming is not a hoax and there is a rapid increase in Earth’s average surface temperature due to greenhouse gases released as people burn fossils. NASA states that the “key indicators of global warming are based on surface, satellite, and ocean temperature measurements, satellite measurements of energy imbalance and of receding glaciers, sea ice, and
