Informative Speech Outline Global Warming Essay

Climate change has affected us in many ways, but it was even more influential on organisms and their community. The Earth is gradually heating and we are left to deal with the consequences. Homes are being destroyed, organisms are dying, and resources are running low. Since 1880, Our Earth’s temperature had increased by about 0.8 degrees Celsius. Climate change is affecting the Earth and scientists say that one more degree will greatly affect people from all over the world. There are many consequences of climate change and each one has a great impact on all of us, but organisms’ homes are being destroyed and thousands of species are dying out. These organisms are imperative to our world and how it functions.

Global warming to date has certainly affected species’ geographical distributional ranges and the timing of breeding, migration, flowering, and so on. The most well known study to date, by a team from the UK, estimated that 18 and 35% of plant and animal species will be committed to extinction by 2050 due to climate change. (Can animals and plants adapt to global warming?, 2017 )

Shifts in temperature and precipitation will be a shock to fragile ecosystems which depend on specific climatic conditions. Many species will be unable to adapt as fast as their environment changes and face sharply reduced numbers or extinction. Scientists estimate that a warming of just 2 degree will put as many as 30% of the world's species at risk of extinction. Plants and animals aren’t the only ones feeling the pressure of changing ecosystems. Many regions will face severe water shortages in a warmer world, creating the potential for conflict. It is believed that the genocide in Sudan’s Darfur region is at least in part a response to water shortages resulting from global warming.

In this journal they stress that the change in global temperature presents a clear and urgent challenge for all species. The alteration of the atmosphere and the climate is going to have consequences for every living thing. Over the years each specie has become well adapted to their conditions of life through natural selection, Mutation is one of the adaptive processes. Environmental variability is going to cause a variation in strength and direction of selection over time. One of the reasons to why selection is changing direction is because the offspring grow up in different areas and at different times. If the surrounding conditions prove unfavourable then the species will not continue to reproduce so therefore the population will begin to

Climate change, or global warming, is a reality plaguing us, and if we work together, we can prevent it. Our planet is changing. It always is, always has been, and always will be, yet it doesn't have to be for the worse. Our planet’s heat, light, and some of its energy is

This is because species will not be able to adapt and migrate quick enough to keep up with the warming of the world (“Climate Change Impacts and Threats). Climate change also has the possibility of harming humans as well. An increase in heat has the potential to kill if temperatures do not drop. The heat can cause severe droughts and can cause wildfires which are dangerous to humans and animals (“Global Warming Effects On Health”). Many people believe that this is just a normal cycle in weather, but it is

A. Restate thesis: Natural disasters are growing larger and more dangerous, and exotic species are dying as a result in the climate shift. Humanity must act now to reduce and reverse global warming

Climate change will not only accelerate the species extinction rate, but also bring a higher chances of survival of certain endangered species, which indicates that the impact of climate change on biodiversity is double-sided (Bellard et al. 2012).

After calculating a global mean extinction rate and figuring out which factors came into play, Urban concluded that extinction risks rise as global temperature rises. It is important for us to observe the effect that climate change has on extinction because, as Urban mentioned, “0 to 54% of species could become extinct from climate change”.

Global warming is a controversial topic, widely discussed among today’s society. It is significant because it deals with the opinions and beliefs of many individuals. It also creates controversy and provides society with the opportunity to express itself and its beliefs. Many people believe that the conditions of the climate have no correlation to human behavior and that nowadays, people exaggerate the impacts of climate change. However, these individuals fail to recognize the truth behind the topic. Global warming is both a real and serious threat to our existence that humans must address by altering their actions and behaviors.

We are all well aware of climate change and the consequences that follow it, aren't we? Melting polar ice caps, disappearance of bees, greenhouse gases, extinction of animals - the list goes on. The world’s top scientists, including Stephen Hawking, all agree that climate change is one of the biggest threats facing our world and if we don’t act now to try to prevent it, things could spiral out of control.

Climate change is already beginning to affect animals and plants that live in freshwater, rivers and lakes. As air temperature increases water temperature also do. Some species are already migrating to waters at higher altitudes and latitudes. However, some of them cannot go any further because they are already at the northern or upper limit of their habitat. Is species cannot adapt to new habitat that will be at risk or even become extinct. When species move it affects the food web. This can result for species to become extinct. Furthermore, other species are migrating too early because of the different seasons temperature change. “Warmer springs have led to earlier nesting for 28 migratory bird species on the East Coast of the United States”. [ Similarly, plant production is also being affected since some plants need a certain temperature to

Global Warming has a huge affect on our daily lives and on animals. We lose a bunch of natural resources, especially fresh-water, because it melts into the salty oceans; however, attempts have been made including the slowing down of global warming by stopping the usage of fossil fuels; whether the attempts have been successful or not. The earth’s temperature is slowly increasing which is a massive long term factor on inhabitants all over the world. The Amazon Rainforest has also experienced many problems due to deforestation and the water circulation throughout all of the plants and trees. Global Warming is exponentially increasing causing the rapid melting of glaciers, which leads to ocean currents changing and

There are many opinions for and against the idea of climate change. With all the different opinions, it can be hard to know what is true and what is just fake news. It’s no wonder people get so confused on the issue. Two main arguments that I will be addressing in this report is whether or not the Earth is warming and if in fact the earth is warming it does it affect plant or animal life.

Impacts of climate change are increasingly felt by Earth’s inhabitants including us, humans. The current warming, which is only one degree Celsius, has affected different ecological processes such as “species’ genetics, seasonal response, overall distribution, and even morphology” (Hance). Species are suddenly disappearing. A study conducted by “PLOS Biology found that more than 450 plants and animals have undergone local extinctions due to climate change” (Hance).
