“We cause global warming by increasing the greenhouse effect, and our greenhouse gas emissions just keep accelerating,” (John Cook “Quantifying the Consensus on Anthropogenic Global Warming in the Scientific Literature,”) Most scientists agree that planet’s temperature has risen 0.5 degree Celsius since 1900 and will continue to increase at an increasing rate. (Weeks, Jennifer. "Climate Change.") As a result, the world is getting warmer. Rising global temperatures will speed the melting of glaciers and ice caps and cause early ice thaw on rivers and lakes.
Also, an engineer Guy Callender creates a theory that larger amounts of carbon dioxide in the atmosphere are causing global warming with the rising global temperatures occurring around the same time, however, meteorologists did not believe him at the time and the dismissal of Callender's theory emphasizes the start of the controversy of the causes of global warming (A brief history of climate change, 2013). During the 1960’s, scientists discover that the effects of global warming over time will cause sea levels to rise from Antarctica's ice sheets melting (The discovery of Global Warming, 2017). Awareness had finally begun over global warming at the beginning of the 1970’s with Earth Day being celebrated for the first time (The discovery of Global Warming, 2017). Last, studies of global warming explain about how much damage in terms of global GDP would be caused by this issue first suggesting that global warming will have an effect financially as well as the environment. Overall, this international issue has been studied since the early nineteenth century, created major impacts over time, has changed the Earth’s environment, and economies
The planet has become much warmer everywhere. Ice has been melting worldwide so that the sea level has risen rapidly. Thus, global warming may cause numerous disasters such as hurricanes and tsunamis. The situation of global warming is severe right now, and it leads to public and animal endangerment. Polar bears may disappear as the sea ice continues to melt.
Each year since 1992 has been recorded as some of the warmest years on record. Signs that global warming is occurring are evident: global average air and ocean temperatures have increased, snow and ice are melting over widespread areas, and the sea level is rising (Union of Concerned Scientists). An increase in global temperature will have many dire consequences. Higher maximum temperatures will cause an increase in heat-related deaths. Heat stress will occur in livestock and wildlife.
Anthropogenic (Human) Causes It is obvious that the Earth`s climate is changing. For the past ten years we have been listening, reading about global warming, the greenhouse effect, rising sea levels and world`s temperature, melting of the icebergs, etc. These are only few of many visible effects of climate change. Scientists have always been quibbling whether the change is caused by human or the causes have natural origin. The Earth`s climate has always been changing.
Weather forecasts are more frequently warning us of extreme weather conditions. Global warming is undoubtedly the major cause of the intense fluctuations in the weather, but today’s improved technology means that weather forecasts are more accurate and can be updated continually. Global warming is responsible for causing the unusual weather patterns that the world has been experiencing for the past few years. Global warming is the heating of our planet due to increased levels of carbon dioxide, causing the ice caps to melt and temperatures to rise. Ten years ago a typical New Zealand summer would be warm and dry, with camping a popular summertime activity.
From the year 1991-2012, there have been 13,950 articles on global warming and of these only 24 reject global warming. This, in itself, is significant because it shows our scientific community is in agreement that our planet is getting warmer and that global warming is the cause. The warming of our planet is causing glaciers and ice sheets the world over to melt, which in turn causes our oceans to rise and we are losing coastlines at an ever increasing rate. These changes in our oceans will also significantly impact our planets eco-systems from plants to animals and on to insects. Around the world, glaciers and ice sheets have been retreating for at least the last century and have increased in the past decade.
Although the issue did not start to gain national attention until the early 2000s, scientists have been studying atmospheric gases and the effect that human consumption of fossil fuels has on the atmosphere and climate since the early nineteenth century (Rich). The overwhelming consensus among scientists today is that the climate is changing drastically and humans are causing it through specific, preventable actions (Rich). Global warming is caused by an increase in greenhouse gases, which, under normal conditions, it (the greenhouse effect) is what makes life sustainable by keeping the earth within a constant range of temperatures (Gore). About 30 percent of the light and the heat of the sun is reflected back into space, either by clouds, or by the earth’s surface (especially ice, which is particularly reflective.) About 20 percent of the light and heat from the sun is
In this essay it would be compared and contrasted the viewpoints on global warming, and discuss about the different issues that people say cause the global warming as well as the defensive points of those supposed causes that affect the environment and cause this effect. It is true that throughout the years the global warming has increased a lot, and everyone can be a witness of that by watching how the weather has changed through the years and it is clear that it’s not the same weather as years ago. It’s clear that humans have caused this during the past century as we create new things and pollute more each time the environment, but also due to those technological advances we have a lot of new things and due to those advances we have made conscience of this, in the past years it is said that the ozone layer has started to regenerate which is a start. Most people blame the global warming on scientists and industries, but it’s not just them who affect it’s everyone and everything causes global warming, today people can’t go a day without causing global warming. This is a very important issue that has been more noticed everyday, people are trying to change their daily routines to help but it is still of great concern that we should start doing something extreme to help with this issue.
Greenhouse gases are mostly comprised of carbon dioxide and methane. According to the Environmental Protection Agency (EPA), “greenhouse gas emissions caused by human activities have increased by 14 percent from 1990 to 2008” (Climate, 2010, slide3). In the last century, the carbon dioxide “concentration in the atmosphere has risen from 280 ppm [parts-per-million] to more than 380 ppm because of the industrial activities of humans” (Ruddiman, 2008, p. 86). We’ve had strong levels of carbon dioxide in the atmosphere in the past from volcanoes, but what does this really do to the environment? First off, it raises the temperature, and also the excess carbon dioxide that does not go into the atmosphere eventually gets dissolved in the oceans causing them to acidify.
