A Report From The National Air And Space Academy

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.

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.

The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.

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

A study shows that there was a 97% consensus among scientists who were interviewed said that global warming is caused by humans in 2015. The number is always changing considering the fact that there was a 100 percent consensus by 2004, with a percentage of 91 scientists in agreement in the beginning of 2014 with a 93 percent consensus by the end of 2014. (Friends) All of these scientists believe that global warming is being caused by and can be prevented by humans. They see that sea levels are rising because of melting ice caps, the number of immense wildfires is increasing along with the length of the wildfire season, droughts are becoming more severe, storms are becoming more extreme and common, and dangerous heat waves are becoming an issue. Sea levels rising dramatically increases the risk of flooding, especially in the Gulf of Mexico and U.S. East Coast. Similarly, more rain falls during the heaviest downpours, increasing the risk of flooding events even more with the temperature increase caused by climate change. Scientists see that climate change has significant implications for our health, including increased air pollution and a longer and more intense allergy

Global warming has been a major concern and has greatly affected the environment around the world for years. Andrew Revkin stated in a New York Times article entitled “A Closer Look at Climate Panel’s Findings on Global Warming Impacts” that climate change throughout the 21st century will lead to increases in ill-health in many regions, as compared to a baseline without climate change. There have been a number of debates regarding this controversial topic, though most of the scientific community can recognize the existence of global warming. Many often question if this effect on the environment is caused by human activity or natural cycles. About 95 percent of scientific studies prove that global warming is essentially caused by man.

The Earth’s temperature has been rising over the years. Sail Bhattacharya a professor & head of a medical college claims that over the last 8000 years, Earth’s surface temperature raised by 1 degree Celsius only (1). He also said, at the present rate of global temperature would rise by 2.5 degrees Celsius by 2050” (1). It’s a fact that the earth has gotten warmer over the years. At this moment the temperature hasn't raised much, only 1 degree Celsius. It may seem like it’s not a big deal, but it actually is, because the rising temperature rate is increasing as time passes according to Sail Bhattacharya (1). The temperature rising might not cause much harm now, but can badly affect us or whoever is living on Earth in the future.

Nowadays, the whole world are paying attention on the controversy about climate change and global warming. Hot topics include whether global warming is occurring, warming level in modern times, causes, effects and what that action should be taken (Science Daily). On one hand, there is a strong consensus that human and industries take main responsibility for the rapid increase of global surface temperatures in recent decades, and greenhouse gases such as carbon dioxide is the major cause of global warming. Meanwhile, some people that come from organizations with

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.

There has been a rise in average temperature by 1 degrees Fahrenheit over the last 100 years. This rise to due to the human effect on the Earth.

In this essay, what I understand is that conspiracy theorist is defined as a point o view by a topic that lacks of unclear explanations. Any person who participates in the discussion with its own or a different idea can fit into this category.

However, it is the argument that is against human activity being the primary cause of global warming that provides a superior explanation to this currently unknown global phenomena we call global warming. Despite the overbearing support against this argument, there is too much factual evidence about the complexity of the atmosphere and all of its elements that outweigh the predictions being made and then amplified significantly. Using supporting facts leads to a superior argument than using mathematic estimations, which consistently fail to meet their expected results. The changes in climate, including temperature change and rising sea levels, have all been happening for thousands of years providing historical evidence to show this change in climate as a natural occurrence. The most critical aspect of the argument is that rising levels of atmospheric CO2 do not necessarily cause global warming, which contradicts the core thesis of human-caused climate change as stated in a publication made on ProCon.org where the director of Greenpeace International Patrick Moore spoke on the relationship between the CO2 emissions from human activity and global temperature. He states that "there is some correlation, but little evidence, to support a direct causal relationship between CO2 and global temperature through the millennia” (ProCon.org). It is important to acknowledge that regardless what the actual

Global Warming also caused very hot weather which is bad for humanity for having too much heat, people can have heatstroke because of this. Scientists who assess the planet's health see indisputable evidence that Earth has been getting warmer, in some cases rapidly. Most believe that human activity, in particular the burning of fossil fuels and the resulting buildup of greenhouse gases in the atmosphere, have influenced this warming trend. In the past decade scientists have documented record-high average annual surface temperatures and have been observing other signs of change all over the planet: in the distribution of ice, and in the salinity, levels, and temperatures of the oceans. Most humans believe that it is their fault, which is true because humans do not take care of their

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

Global warming has become a well conversed topic among scientists and peoples in the world today. There are extremists who do everything possible to stop contributing to the warming, but the average person does little to alleviate the issue and in many cases refuses to acknowledge that there is a problem at all. Dating back to millions of years ago, even before humanity was born, the world has always experienced one form or another of warming; so the warming seen today is not as bizarre as many may think. The prevalent saying that history often repeats itself, is no joke when discussing global warming. As to what is kindling the current warming, that is where a query is imposed. Scientists from around the globe have theorized close to every possible contributor to the warming seen today, and the conclusion that present occurrences of global warming are being evoked by human interference has become evident.
