Modern Day Climate Change

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,

In the modern world there is no more universal debate than Climate change. Recently, the

According to the Climate Change report from the National Academy of Sciences and the Royal Society, the Sun’s “variations have played very little role in the climate changes observed in recent decades” (Society & Academy, n.d.). Moreover, data provided by the report shows that even during periods of low solar activity, the Earth’s average surface temperature has still increased.

It is not surprising that the Earth’s climate has changed rapidly through the century. What really comes as a surprise, however, is that almost everyone acknowledged the notion that climate change is man-made. Why particular phenomenon existed? With innumerable signs given by our planet, like global sea level and temperature rise and shrinking ice sheets, it is beyond doubt that our climate is changing. Yet, climate change authentically is an action of the nature itself.

Many people think that present-day climate change is similar to paleoclimate change, but this is only true when looking at the effects of climate change, the trends in temperature, and the trends in greenhouse gas levels, which have all stayed the same. By applying the principle of uniformity, we know that many of the current processes, such as plate tectonics happened in the same way in the past. In order to use climate proxy records, we have to apply this principle to be able to compare the data about the current and past environment with equal weight. For example, we assume that the ice cores reacted the same way to changes in air composition and temperature in the past, such as the mid-Cretaceous, as they do today, so that we can make fair statements of whether or not the air composition and temperatures have changed or stayed relatively similar. We

Did you know that Climate change is affecting people all around the world? Climate change is a very bad thing that has been going on for hundreds of years. So many things are being affected by climate change. Things that are being affected are trees, plants, animals, and even people. One reason that climate change is happening is that the earth is always in orbit so the climate is always changing. Climate change isn’t only nature, climate change is caused from humans, the sun, and animals. We are causing climate change by burning things. Scientists predicted this and they’re using models to predict climate change. Snow leopards in the Himalayas are dieing off. Asian Rhinos depend on floodplain grasslands and climate change changes the seasonal patterns the Rhinos go off of. Orang-utans are also one of the species at risk from deforestation. The ice that the Polar Bears use for homes are slowly starting to melt which means they are becoming more and more crowded.

Climate change has been an argument going on for years now. Since industrialization, there has been numerous debates asking the question: Is climate change due to natural evolution or is it the human species causing this change? Scientist’s try their best to predict the future, but it is just that, a prediction. Take a meteorologist for example. Your local weatherman states that it is going to rain that day and you take all of the necessary precautions for this incident only to see that it does not in fact rain. Climate change has not only been debated by scientists around the world, but also become a major political debate as well. Politicians are generally out for one thing, and that is popularity. Climate change is a topic that is constantly changing. You never know what to believe in their speeches. This brings me to my point, which is you never really know what is going to happen.

“Climate change is not just a distant future threat. It is the main driver behind rising humanitarian needs and we are seeing its impact.”

Global climate change is no big secret--things are heating up and humans are starting to

Global climate has been changing throughout history; just in the last 650,000 years there have been seven cycles of glacial advances and retreats. The abrupt end of the last ice age, about 7,000 years ago, marked the beginning of the modern climate era and of human civilization. Global warming has gradually increased the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. There is compelling evidence of rapid climate change because of different sea levels rising, glacial retreat, warming oceans, shrinking ice sheets, extreme weather, ocean acidification and decreased snow cover.

A tremendous amount of concern regarding climate change has emerged recently as most of the human population is adversely affected by it and adapting to current and projected rates of climate change could be very challenging. There have been observed increases in global average air and ocean temperatures, widespread melting of snow and ice, rising global sea level and small increase in growing seasons (Learner, 2007). Although climate change is attributed to both natural processes and human activities, this term has become synonymous with anthropogenic global warming (Berliner, 2003). Humans have been modifying the environment with processes associated with industrialisation and urbanisation, resulting in increased emissions of carbon dioxide (CO2). The excess amounts of CO2 generated primarily due to burning of fossil fuels like coal, oil and natural gas, as well as the release of gases such as methane, nitrous dioxide, aerosols and other pollutants has led to the enhanced greenhouse effect, causing an unnatural warming of the Earth’s surface (Berliner, 2003). It is estimated that the global temperature will increase substantially by the year 2100 and that this warming will have widespread and irreversible impacts on human life and natural ecosystems (Learner, 2007). Therefore, there is a universal consensus for the need to deeply cut CO2 emissions to limit this temperature growth to below 2 degrees Celsius (McKibben, 2010).

Global warming first became evident during the 19th century when it became evident when temperature increases were beyond constraints of natural variability (AGU, 2013). Climate change was first brought to the public’s attention by head U.S. Weather Bureau 's Division of Climate and Crop Weather who reported that the global climate system was experiencing an increase in temperature (Spencer Weart & American Institute of Physics, 2015). To explore how climate conditions have varied throughout Earth history, paleoclimate reconstructions are used to extend records back hundreds to millions of years (IPCC 2013, pg.2).

We've been told repeatedly throughout the years that our earth's climate continues to change. However, it is rare that during these conversations the possibility of there being an unceasing increase in the temperatures in our oceans due to climate change brought up specifically. There being a potential rise in temperature and the ramifications that such a thing would bring are what this particular article is written about. Even though the study itself took years to conduct, its' initial hypothesis of the various scientists involved was somewhat of a simple one, it was that "[c]limate change will dramatically alter life in the oceans" (Zimmer, 2017). This seems like a pretty safe assumption

“Climate change is undeniable. Climate action is unstoppable.Climate solutions provide opportunities that are unmatchable” ( Andrew Hansen,2017).Scientists are concerned about some of the consequences of global climate change. There are several things that can cause global climate change. But the main reason of this is human activities. Humans play a big role in global climate change. Human activity is responsible for global climate change and it has to deal with greenhouse gases, air pollution, the rise in temperature.
