Persuasive Speech On Global Warming

Earth is not what it was before, it is rapidly changing due to human activity and natural causes. If humans continue these trends by harming the Earth, it would constantly affect the environment, plants, animals, the earth we live in and humanity. In this essay I will be explaining; What climate change is. How does climate change affected the biodiversity on the Great Barrier Reefs. What are some prediction for future effects of climate change. How this will impact biodiversity on the Great Barrier Reef. How it will affect other ecosystems and what locals and global consideration to reduce the impacts of climate change.

Climate is an atmospheric change in the average weather in an area over a period of

Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities (“Carbon Dioxide Emissions”). In 2012, CO2 accounted for about 82% of all U.S. greenhouse gas emissions from human activities (“Carbon Dioxide

Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).

When you hear the words “climate change” what comes to mind? Probably weather and the changes. Many of us watch the news or use an app on our cellphones/electronic devices to keep an eye on the weather for the day, week, or even the month. But, there is actually a difference between weather and climate. Weather is actually “the changes we see and feel outside from day to day. It might rain one day and be sunny the next. Weather also changes from place to place” (Dunbar, 2014). Whereas “climate is the usual weather of a place. Climate can be different for different seasons. Different places can have different climates” (Dunbar, 2014). This paper will focus on the ins and outs of climate change, specifically focusing on what climate change

Another thing we should consider is anthropogenic climate change that refers to the production of greenhouse gasses emitted by human activity. By examining the polar ice cores, scientists are convinced that human activity has increased the proportion of greenhouse gases in the atmosphere, which has risen over the past few hundred

Climate is the average of the weather of a region, and the climate of the Earth is the climate average of all the regions. Based on that, climate change is a change in the average climate of the Earth. According to the NASA, “Some causes of climate change are natural. These include changes in Earth's orbit and in the amount of energy coming from the sun. Ocean changes and volcanic eruptions are also natural causes of climate change”

Climate Change is the significant change in the climate and distribution of weather patterns on Earth ranging from the last decade to millennia earlier.

Most of the scientific are recognizing that climate change is due to concentration of greenhouse gases rise in the atmosphere at a high level. It has made the Earth's surface temperature to warming up and warming temperatures have created the changes in the weather. Currently, the average temperature has increased to 0.3-0.4 degrees in the past tens years . The Earth's warming temperatures make the ice of the Himalayas and Antarctica, the Arctic and other regions has melted and this will make the sea level rise. Sea level rises up about 28-43 cm. But the sea level can rise higher because it depends on emission of the greenhouse effect and the impact of human-caused.

One of the dig problems on how global warming is affecting the earth is the impact on the trees like the true ecological kings of the jungle,

Methane is a more active greenhouse gas but it is less abundant. It can be produced naturally and by human activity emitted from waste sites, agriculture farms, and rice cultivation industry[C]. One major reason behind the release of methane is the production of oil and gas from fracking, which releases methane into the ground surface and leaches into surrounding water ways. Nitrous oxide is another powerful greenhouse gas produced by human activity by agriculture, fossil fuel combustion, organic fertilizers. Since the massive rise of population, the global demand has increased these levels for the production of agriculture needs and fertilizers. These greenhouse gases are

The problem of climate change is a regular topic of debate. A debate that is rightfully being drilled into the forefront of everyone’s thoughts because the damage has started to become more apparent. The repercussion has started to manifest themselves through altered weather patterns, as the Earth’s temperate zone have become less, for lack of a better word temperate. Unless

Since 1880 (when reliable record keeping began) the Earth’s average temperature has increased by 0.8-1.0 degree Celsius. At this small amount of warming familiar global weather patterns are being disrupted, the polar and greenland ice sheets are melting, storms are more intense and frequent and tropical diseases are spreading into higher latitudes and altitudes.

2014 broke records in terms of highest temperatures to date. Around this time, droughts, wildfires and other notable weather episodes lessened in rarity. These new visible extreme events were quickly blamed on climate change by the masses. However, it may or may not be true that these climactic incidents are symptomatic of an environmental imbalance. Climate change is defined as an accentuated difference in averages of weather circumstances or in intense meteorological occurrences for a given time. Studies do show that temperatures are increasing, that water levels and reserves are in displacement, that abnormally strong weather occurrences are on the rise and that oceans are acidifying. Scientists state that data is limited time-wise and in some areas around the world causing some inconclusive results, especially so in the field of severe weather events, but studies of this data remains substantial.

Climate change is a major concern of the global community. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4) stated that global surface temperature have increased by about 0.74 ◦C between 1906 and 2005. Extreme high temperature events have become more frequent and more intense in recent years in some regions.
