Dr. Hayhoe: The Cause Of Climate Change

Do humans play a part in climate change or is it just mother nature? I believe that humans are play the main role in climate change. Since the Industrial age humans have played the main role in climate change because of greenhouse gases which cause the greenhouse effect. The main greenhouse gas that we emit is carbon dioxide from the burning of fossil fuels, the other greenhouse gases that we emit are methane, Nitrous Oxide, and Fluorinated gases. These greenhouse gases will absorb and re-emit some of the infrared radiation that would normally be radiated out into space. Another cause of climate change is deforestation, ever since humans started cutting the forest down the climate has changed globally.

Humans are to blame for global warming, there is no question about it. Humans and human actions are causing a rise in temperature worldwide. We have recorded a steady rise in temperature for the last fifty years. This rise is caused by an estimated 95% of human actions.Humans are to blame for global warming because of deforestation, population growth, and the use of non-environmentally safe products.

What is climate change? Climate change is weather over a long term period, such as hot summers and cold winters. As the late 20th century these patterns/ increasing heat has been occurring more frequently and can cause climate change disasters, some may believe that humans are responsible for these occupations. Some scientist believes by humans releasing fossil fuels, harmful gases and populating is the only reasonable theory on why climate changes occur. As recent discovery scientists are skeptical if humans are really the primary cause and if this is a part of the world’s nature cycle?

Is climate change caused by mankind or is it simply a natural occurrence? If the answer were as easy as “yes, it is 100% caused by humans,” or “no it’s not at all caused by humans,” there would be very little room for argument. Two questions need to be investigated: 1) Is it probable that such a young species could really be responsible for causing enough air pollution in approximately 250 years, from the 1700’s to mid 1900’s, to alter the climate of the entire planet? 2) Is it probable that mankind’s industrialization from the

When a volcanic eruption takes place, it releases carbon dioxide and aerosols such as ash particles and sulphur dioxide into a layer of the earth’s atmosphere known as the stratosphere. The aerosols include substances such as soot, salt crystals, viruses, soot and bacteria. While the release of the greenhouse gas carbon dioxide contributes to global warming, substances such as ash particles and sulphur dioxide building up in the stratosphere absorb and reflect the sunlight, making the earth a colder place. According to the British Geological Survey and the UN Geological Survey, around 100 to 300 million tonnes of carbon dioxide are released from land based and underwater volcanic eruptions. The eruption of Mount Pinatubo in June 15, 1991 was

Is global climate change man-made? Global temperature has been changing for the past couple of decades. This leaves researchers to believe that mankind is to blame for this abrupt change. Life on earth depends upon the average climate that has been around for thousands of years. Without this favorable climate, life on earth will be unsustainable. Those who argue that climate change is not affected by humans state that the emissions humans put into the atmosphere are too small to have an effect on the climate. Either way climate on earth is changing at a concerning rate and is a major issue.

Volcanic eruptions are very problematic to predict despite how much technology has advanced over the generations in terms of magnitude and the impacts that it has had on people throughout history. An eruption is defined as “The ejection of molten rock, steam, etc., as from a volcano or geyser” (Dictionary.com, 2016). There are many reasons as to why volcanic eruptions are so difficult to predict and there are many examples of volcanoes down the ages that have impacted humans tremendously and posed potential risks to people when prediction was not able to influence an evacuation or contribute to saving lives. The size of the eruption is a factor that; when not predicted can intensify the impacts of an eruption enormously and result in a disaster.

Volcanic eruptions result in climate change, danger to people, and can cause other natural disasters. Eruptions have major effects on the climate. The gases and particles from the eruption can shield the Earth’s atmosphere from solar

Volcanic eruptions have occurred very seldom throughout the years, but when they erupt the amount of carbon dioxide they produce is massive. When volcanoes erupt, they produce tiny reflective particles that go into the air and the atmosphere. These particles however, reflect incoming energy from the sun not the radiation that is trying to escape. This would cause the earth’s surface to cool not warm. New ground, air and satellite measurements across the globe show that the one or two volcanic eruptions each year have deflected almost double the amount of solar radiation than previously estimated (“Could volcanoes help slow global warming”). When a volcano erupts, it produces small droplets of sulfuric acid which combine with oxygen and stay

been researching this for a while and got some information or proof if you could say in why us humans have been causing it. They say they know that there was problems with cooling has happened in past long before humans even existed, but now since we do little things on are body like fingerprints is causing the whole thing. Fingerprints that us humans leave on Earth’s climate are turning up the diverse range of records. Also, scientists are that today's warming is primarily caused by us humans putting too much carbon in the atmosphere. Scientists now have a very high confidence about humans causing the global average temperature increase.

I think climate change is caused by human neglect and unconscious spoiled behavior. Through this behavior and neglect a buildup of greenhouse gases has occurred through everyday living. Humans choose to drive and use gas powered equipment and machinery over electric powered ones. Gas powered byproducts cause pollution, adds to a buildup of greenhouse gases.Products used in our daily lives for personal hygiene and daily living contain CFC’s a big cause of green houses gases, which I believe is the true culprit of climate change. These greenhouse gases are called Carbon dioxide,Methane,Nitrous oxide and Halocarbons. All four gases can affect climate change. My evidence for this is ‘“when humans burn coal oil,and (fossil fuel) to generate

Most of the blame for climate change over the years especially after the 1850’s has been placed on humans. As long as modern humans have roamed the earth, they have been upsetting the natural balance of the earth. People have did this by clearing areas of land, killing animals, polluting water, etc. Before the “modern human”, people like the Native Americans cared for the earth. They respected the land and the people that cared for it. Unfortunately, people don’t care anymore. Until recently, people did not care for the earth. People did not realize the harm they were causing it. Now we know how detrimental things are that we continue to do and used to do.

The haze effect is defined as when “Suspended particles, such as dust and ash…block out the earth's sunlight, thus reducing solar radiation and lowering mean global temperatures.”( http://www.geology.sdsu.edu/how_volcanoes_work/climate_effects.html) While this statement holds true, it was found that it was not only the dust particles that caused lowering mean global temperatures, but it was also the discharge of sulfuric-rich gases; the main gas being SO2. According to the U.S. Geological Survey (USGS), “Emission rates of SO2 from an active volcano range from <20 tonnes/day to >10 million tonnes/day...”

Humans, us, and everyone you know is now a part of this and they are all guilty even though you say you’re not but in reality, everyone single one of us is to blame for this cause. Now in day we here of this often, Global warming. Global warming is cause by mostly human activity and this can impact us in the near future if we are not carful. There are many ways humans play a big role in global warming like polluting, burning fossil fuels and chopping down forests. Are humans really the main reason to have this effect on our earth?

The volcano is a common form of landform. Under the crust 100 to 150 kilometers, there is a "liquid area" with high temperature and high pressure gas containing volatile components of the molten silicate material, magma. Once magma rushed out of the surface from the weak crust it becomes lava, then a volcano form. Volcanoes are divided into "active volcanoes", "dead volcanoes" and "dormant volcanoes". “Active volcano” is erupting or is expected to erupted once again. “Dormant volcanoes”, even live but not now erupted, and volcanoes that may be erupted in the future can also be called active volcanoes. “Dead volcano” is last eruptions that have been long ago and proved to be erupting volcanoes in the foreseeable future, known as extinguished volcanoes or dead volcanoes. Volcanic eruption is a bad thing, supposedly people should stay away from the volcano that may be the outbreak. However, things are very strange, often the distance from the volcano, the population is denser. Volcanic ash is very fertile and conducive to the development of agricultural production,
