Since 1880 (when reliable record keeping began) the Earth’s average temperature has increased by 0.8-1.0 degree Celsius. At this small amount of warming familiar global weather patterns are being disrupted, the polar and greenland ice sheets are melting, storms are more intense and frequent and tropical diseases are spreading into higher latitudes and altitudes. Deniers of climate change will say that warming has stopped since 1998. There are a few flaws in this reasoning. First, “16 years of data does not meet the World Meteorological Organization’s criterion for a legitimate climate data set. The WMO defines at least a 30-year period for establishing a climate trend.” (Farmer 14) Although there has been a slight leveling out in the rate of warming since 1998, similar trends were observed in 1900, 1940, and 1960. Each time the warming slowed temporarily, then rebounded higher than before. Much recent research indicates that during these lulls the climate was still warming, with 93.4% of heat energy introduced to the system going into the ocean. Remember that the deep ocean is absorbing more heat than at any time since human civilization began. As discussed earlier the vast majority of Earth’s energy comes from the sun. Solar variances have been hypothesized to have a hand in the changing of the climate. However; solar irradiance has been closely monitored by NASA since 1975, and changes in solar output have not been nearly robust enough to cause such dramatic warming.
Recently, there has been a warmer climate change, causing earth to get warmer, as well as negatively affecting earth, animals, and humans. Since 1880, the average temperature of earth has risen about 0.8 degrees celsius, which is a drastic change, even though it may not seem like much. Also, there has recently been a large amount of greenhouse gases being released, which is a large cause of why earth is getting warmer. Many consequences come with this change in climate. The fast-changing climate on earth has caused countless consequences that could permanently affect the earth.
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
Global warming is the steady heating of Earth’s land, oceans, and atmosphere caused primarily by human activity. Climate change is one of the world’s biggest challenges right now, from people actively arguing that it doesn’t exist- to other’s who don’t care enough to do anything about it. There’s evidence showing that climate change is happening and affecting our world now and from what it seems, if action isn’t taken, major consequences will soon arise. Most of the world’s land mass has experienced a 0.2-1.0 degree Celsius average temperature increase since the 1970s, the temperatures of the Artic has increased at almost twice the mean global rate. Climate change is caused by human factors such as greenhouse gases and ozone depletion and because humans are so dependent on fossil fuels in their day to day lives, the issue at hand is only going to get worse.
According to the statistic, average temperatures have climbed 1.4 degrees Fahrenheit around the world since 1880, and the rate warming is still keeping increase. The 20th century’s last two decades were the hottest in 400 years and possibly the warmest for several millennia, which is what people say global warming. Global warming not only influences the temperature but also have many bad impacts. In the article “Seafarming at the End of the World” by Peter Meehan, he mentioned that some of the ocean species are going to be driven extinct by climate change. Similarly, in the article “Global Warming Impacts” the writer shows that global warming will have bad influences in many different ways.
artificially risen over the past one hundred years. The climate is negatively affected when we
It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).
According to scientific research, the average temperature of the earth has risen by between ten and twenty degrees Celsius (M.L. Weitzman, 2008). These high temperatures could well be described as a ‘recipe for disaster’, and could produce results that would be catastrophic on a global scale. What is more alarming however, is that there is already a lot of evidence of predicted results of climate change, for instance, in Australia especially, severe draughts have been common in farming areas in the last few decades, there has been an increase of intense and extreme weather events, for example floods, flash floods, tsunamis, earthquakes and tornados, almost all of the natural disasters listed have occurred for ‘unknown’ reasons in the past few years. Rises in sea water level and temperature due to higher acid levels caused by global warming, threaten the existence of species and in some areas, entire eco-systems resulting in the loss of natural biodiversity. ‘Climate change is pushing the world to the verge of environmental and economic collapse, whether global deniers want to believe it or not’ (N. Klein, 2011).
Earth’s climate can be observed as an ever changing continuum throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, the end of the last ice age occurring about 11,700 years ago. With climate change being a seemingly characteristic and even beneficial quality of Earth (the end of the ice age did mark the beginning of the modern climate era fit to sustain human civilization after all) it may be easy to disregard the significance of the current period of climate change our planet is in. However, most of the climate changes that occurred before the one beginning around 1950 were attributed to variations in the Earth’s orbit that affect the amount of solar energy received by it. The current
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.
The average temperature is expected to rise over time. With the temperature slowly rising, icebergs are melting in Antarctica which is causing polar bears to have to move. Snow and ice cover has been decreasing a lot already. Sea levels are also rising, if sea levels are rising that can cause floods. More and more floods, droughts, and heat waves have been occurring more than one hundred years ago. With all of these natural disasters happening more often, the human race is having
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
The report concludes, again with “high confidence”, that anthropogenic (human caused) warming has had a discernible influence on many of our planets physical and biological systems. While there are limitations and gaps in the knowledge available, particularly from undeveloped countries, the knowledge available allowed the group to attribute most of the observed increase in the globally averaged temperature since the mid-20th century to the observed increase in anthropogenic greenhouse gas concentrations. The analysis was necessarily limited in the number of systems and locations considered. In addition, natural temperature variability is larger at the regional than at the global scale, thus affecting identification of changes due to external forcing and at the regional scale other factors such as land-use change and pollution, are an environmental
In the last 100 years, Earth’s average temperature has risen by 1.4°F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise from 2 to 11.5°F in the next hundred years (US EPA, 2014). The “drivers,” which are the principal causes making this occur, are very controversial. It is debated whether a change in temperature is due to the work of
The climate changing was first suspected in the 19th century when scientists in britain debated whether Europe was covered by ice in the past. “Guy S Callender suggested that the warming trend revealed in the 19th century had been caused by a 10% increase in atmospheric carbon dioxide from the burning of fossil fuels.” (Harding) The debate intensified by 2005 when a study was published stating that a large scale disruption could occur by 2050 if we do not slow the process of climate change. The debate has now spiraled back to whether climate change is occurring or not. However the climate warming pattern has been increasing exponentially since the 1950’s.
