Climate Change Is The Single Biggest Environmental And Humanitarian Crisis Of Our Time

Climate change is the most serious issue humankind is facing in the 21th century. Future generations depend on our ability to make the necessary social changes, before reaching the tipping point of irreversibility, which will lead the planet into a catastrophe incompatible with life.

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.

Climate change is a issue that widely talked today. As the National Weather Service reports, the hottest temperature records are extending all over the United States since year 2010 (Schlesinger, William H, 2014). It is obvious that our world is heating. Global warming become more and more seriously. With the increase of temperature, many environment problems occur to have huge impact on our urban life, including: the sea level rise, air pollution and drought. These environment problems also endanger our area in a large part.

Over the years, human existence has led to major environmental changes and global impacts. Recently, human activities have led to an increase in climatic changes threatening human life; such as, global warming, rising sea levels, increase in floods, and melting ice caps among other indicators (Klein, 2015). These environmental changes have been brought by rapid industrialization,

Climate change is affecting humans every day, and yet most of us have found that every region of the globe is affected in some way or another. For us here in San Diego, California, in the Western Hemisphere, on the west coast, United States, North America, that impact is felt mostly with rising sea temperatures and rising sea levels. There are noticeable predictions that by 2050, rising sea levels here will rise as stated: “"At least a 16 inch sea level rise is expected in San Diego, Ca by 2050, with a projected rise of 50% by the turn of the century."

Climate change is a challenge facing our planet right now. Long-term effects may develop as a result, causing threats to natural resources, human health, and the economy. The concern is rising with the amount of carbon emissions and greenhouse gases in our delicate atmosphere.

Despite the controversy that surrounds the existence of climate change, there is a high agreement among scientists that human-caused climate change in very real. Over the past two decades, surveys and studies have been done on climate change and the results have shown that the average global temperature has increased by about 1.4 degrees Fahrenheit. The sea level is also rising and heat waves are happening more frequently than before. These events could lead to an abrupt and potentially irreversible climate change but scientists do not know the tipping point for such an event. Therefore, the sooner the inhabitants of earth begin to take action against climate change, the less likely something irreversible could happen.

An issue that is felt throughout the world is Anthropogenic Climate Change formally known as Global Warming. This word wide problem is one that needs to be addressed immediately as well as long term. Anthropogenic Climate Change is the rise of the earth’s temperature caused by human activities. The continuing rise in the earth’s temperature will cause extreme change in our earth’s ecosystems. The predetermined course to our ecosystems relies on climate change and its effects on ecosystems and life as we know it is at a vulnerable state. Anthropogenic Climate Change shifts relations with human life and presents severe biodiversity in

[Abstract: Climate change is the single greatest threat facing our planet. Senator Bernie Sanders, Democratic Party nomination seekers in the US presidential election 2016, repeatedly urges in his campaign: ‘climate change is real, it is caused by human activity, and it is already causing devastating harm here in the United States and to people all around the world.’ Nonetheless but humans are liable to climate change, and are also affected by it with others. This article will focus on our collective and individual moral obligations to reduce greenhouse gas emissions as well as our moral obligations to climate change affected poorer countries in order to argue that we have a moral obligation as a whole. The United States, the wealthiest country in the world, contributes far more than its share of greenhouse gases. It is now clear that these emissions have caused serious risks to the world as a whole, particularly the poorest nations. In response to the question ‘Does an US individual has a moral obligation to impose reasonable curbs on its future greenhouse gas emissions?’ Armstrong and Johnson have advanced a novel and sophisticated argument for the right of individuals to remain stable in their personal emissions. We believe that the general shape of their position is attractive since it (i) grants the individual the right to emit without suggesting that any and all restrictions are permissible; (ii) distinguishes between the relative strength of collective moral

Since the global warming movement began, mountains of evidence and proof of climate change has been collected. Between 1880 and 2012, the global average land and ocean surface temperature have warmed .85 degrees celsius. According to temperature records, there is a global trend of the Earth heating up. Nine of the ten warmest years on record occurred in the 21st century. Glaciers are predicted to continue to retreat, precipitation patterns are expected to change, and sea levels rise on an average 2.9 mm a year. All of these symptoms of climate change will only get worse and have adverse effects on ecosystems and people’s lives. Migration routes will change. Many small island nations will see their home be swallowed up by the sea. Coastlines will change, progress inland. Expensive beachfront property will be underwater. Weather will become even more unpredictable and extreme. Hundreds of species will go extinct from loss of habitat and change of climate. Resources such as fresh water will become scarcer and will be the cause of conflict between nations. When it comes to that, our only option will be to adapt to the new

Currently, people are living in a time of great crisis, that are faced by the gravest challenge that human beings have ever faced; the ecological consequences of our own

The rapid change in our climate due to anthropogenic forces has caused the Earth’s average temperature to rise to an unparalleled level in human history. The amount of carbon dioxide in the atmosphere, as well as the cyclical processes of the Earth and Sun, affect the warming of our oceans and atmosphere. Although processes other than anthropogenic practices modify the climate, our influence on the climate since the Industrial Revolution has been unmatched. According to the Intergovernmental Panel on Climate Change (IPCC), “Recent climate changes have widespread impacts on human and natural systems” (IPCC , 2014). The impact that climate change has on human and natural systems is difficult to quantify, because the effects are complex and slow moving. Although the magnitude of the impact is challenging to measure, it is quite clear that, “Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen” (IPCC , 2014). Equally important, carbon dioxide levels have reached nearly 390 ppm and scientists estimated this number could rise to 500 ppm by 2050 and 800 ppm by 2100 (Hardt & Safina, 2010).

The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it.

Our global climate change has not always been a top concern for scientists, politicians or even our very own view on the rapid rates of global warming data. The drastic change and harm that has occurred to the nature around us has become a huge concern that must be dealt with appropriately and done so in a timely manner, with rapid glacier melting that has caused rising sea levels or the .15-degree temperature increase per decade since the 1900`s we can noticeable see the change our earth has endured due to humans. Even the smallest change of a degree in temperature not just in the U.S but globally has effected many aspects of Earth itself. Just a couple of years ago in the year 2014 our planet reached

Climate change is now a reality which we human beings can ignore only at our own expense. The threat is looming ahead and if we do not actions in a timely manner it would not only have an impact on the current generation but also on the future generations to come.
