The Arctic Sea could be Ice-Free by 2050 According to research, the Arctic Sea is most likely to be fully melted by 2050. This is because of carbon dioxide, also known as CO2. Carbon is the cause of global warming. The average American carbon footprint shrinks 32 square feet of ice each year, and that’s just one American. Multiply that by 325 million, and that’s a lot of ice melting! Sea levels have been rising at an alarming rate, parts of Florida are building drains that cost millions to keep it from sinking, and when high tide comes in, the streets are completely flooded. They have to raise many bridges so that cars can pass by during the floods. As you may be able to tell already, global warming is a huge issue. How much CO2 each

The Arctic Tundra The Tundra is located in the northern regions of North America, Europe, Asia, and Africa. as well as a few regions of Antarctica. The Tundra is the second largest vegetation. zone in Canada. It can be divided into three different sections: the High Arctic Tundra, the Low Arctic Tundra and the Alpine Tundra.
People need to stop and think for a minute, away from the unfounded claims of inevitable catastrophe and think in a well-educated manner about the actual implications ahead. There is too much uncertainty in how emissions actually have affected, and will affect the climate. Upon moderate investigation, weather events that have been blamed turn out to not have any correlation. Science doesn’t know everything of the impacts of carbon dioxide, nor can they ever know. Global climate change is such a popular topic, but it actually seems to turn out to be a lot of misinformed hype and opinion. The public needs to set aside the hype about global warming and consider the facts and uncertainties surrounding it, rather than just swimming with the current.
The use of fossil fuels has greatly increased the amount of atmospheric and oceanic CO2 to a point where it’s ruining the natural flow of the world; the earth’s temperature is rising. As a result, the polar ice caps are melting causing the seas to rise. With only a 1 meter increase in sea level the United States alone could lose over 10,000 square miles of land, and thousands of houses will be destroyed. The effects will be just as prominent around the world: many islands will become submerged, 17% of Bangladesh will be underwater, and tens of thousands of people will be displaced (“Global Warming” 3).
We humans cannot help but feel a twinge of regret when we contemplate how we brought forth the plague of global warming by our own hands in the passing years. Aside from rising sea levels as deluging coastal cities and depleting ozone layers as increasing cancer rates, we inevitably come face to face with one simple realization: it’s getting too hot in here. Moreover, we have been devastated by various extremes of nature, with spring frost storms and summer hurricanes arriving with increasing frequency. However, numerous though the causes of global warming may be, the general consensus is that carbon dioxide, which results from the burning of fuels such as coal, is the main culprit; this gas has now formed a high concentration blockade in the atmosphere, preventing heat from escaping and thus increasing the temperatures of our planet. Therefore, after assessing all facts of the problem, I humbly propose that we collect the CO2¬, compress it, and then place it into soda cans. Then, we shall store the soda cans underground, whence the CO2 originally came.
One of the most compelling and difficult environmental problems society faces today is climate change. People do not realize how much the environment has changed for the worse in the last ten years, until they are told that the last two decades of the 20th century have been the hottest in the last 400 years, according to climate studies (Conserve Energy Future). Today, the carbon dioxide levels have reached 396.81 parts per million (ppm). “Carbon dioxide (CO2) has also increased over the last 100 years-- from about 300 ppm to 370 ppm. Interestingly, the majority of these additions have occurred in the last 50 years, when temperature increases have been the slowest” (geocraft).
The impact humans are having on mother Earth is increasing its effects with the rising of sea levels. Global warming is causing polar ice sheets to melt, which is a major cause of adding volume to our oceans. Furthermore, the troposphere thickens, due to greenhouse gases, increasing the amount of radioactive waves that causes the seawater to warm up, resulting in ocean expansion. Most climatologists are expecting a rise in oceans around the world to be between 1.5 and 5 ft by the end of this century.(Harkinson) Some members of our society feel that because climate change is not certain, they are not willing to make a difference to help. Many people are unaware of how rapidly we have impacted mother Earth. The melting of the polar ice sheets resulting in rising sea levels should not be taken lightly. NASA satellites show a 9% decrease in the ice cap each decade. Every six years an assessment report is conducted by scientists, who have noted the need to make a difference before it’s too late. The problem is uncontrolled human activity that takes for granted the resources Earth provides us with. Through this we are facing extinction of many types of flora and fauna, as natural habitats disappear. The IPCC has very high confidence that humans have created much of the global problem. The hottest years have peaked within the last 10 years.
The glaciers are melting hundred times faster than anytime in history. Causing sea levels to rise between 7 and 23 inches by the end of the century. While global temperatures continue to rise the ocean will get warmer impacting sea life. For example, squid and tuna have migrated up to the Northern Pacific because water here in Southern California are not as cold as they use to be to keep them alive. Salmon is about to be affected if northern Pacific if water continues to get warmer. Over the years researchers have seen a decline of penguins have fallen from 32,000 to 11,000 in 30 years.
Ever since the dawn of the Industrial Revolution at the end of the 18th century, fossil fuels have been used constantly, slowly changing the planet’s atmosphere. According to Mann, “the preindustrial level of CO2 was 280 parts per million (ppm)” (N. pag). He predicts that at current rates, we will reach 560 ppm by the end of the 21st century. To make matters worse, Mann states that 450 ppm is dangerous as it will cause an increase in Earth’s average temperature by 2 Celsius. He recommends taking measures to keep CO2 at less than 405 ppm (N. pag). Mann takes note that in 2013, the value managed to reach 400 ppm (N. pag). It is needless to say that the point of no return is right around the corner. Unfortunately, the affects of pollution are already felt around the world. Pollution can cause many health issues and damage several organs in the body. When people think ...
Due to climate changes, we are a “gradual and uncertain rather than immediate and obvious” process, we as humans cannot understand it (Jamieson, 102). In addition, climate change effects have no geographical bounds and because very few people pay attention to events that occur beyond national boundaries, most people are oblivious to its existence. Jamieson makes the point that climate change must be thought rather than sensed, and we as humans are not very good at thinking (Jamieson, 103). On top of that, even if we succeed in thinking that something is a threat, we are less reactive than if we sense that it is a threat. Since we cannot even comprehend climate change's presence in our world right now, it also makes it extremely difficult for us to comprehend how our anthropogenic actions of today will affect future generations all over the world.
...ources Defense Council (NRDC), “Four global warming impacts alone—hurricane damage, real estate losses, energy costs, and water costs—will come with a price tag of 1.8 percent of U.S. GDP, or almost $1.9 trillion annually (in today’s dollars) by 2100” (Akerman 4). Climate change or global warming is neither today’s nor tomorrow’s problem. It is a long term problem that has been affecting us, is affecting us, and at an even much higher rate will affect us.
Background and Audience Relevance: There are always conversations about our planet. We see our earths glaciers melting, weather temperature rising, and pollution affecting our resources. But for some reasons we tend to look away. We should be more aware of this potential event and I’m here to inform everyone about what actually is global warming and the effects of it.
The most destructive human contribution to climate change is fossil fuels combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbons levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation which regulate the earth’s energy. Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57 % of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver,
The hottest recorded temperature was in 2005 which matched the temperature in 1998. Twice in the last decade we've had the hottest temperature on average ever recorded throughout history. Coincidence. I think not. The snows of the Kilimanjaro have basically vanished and in a couple decades Glacier National park is going to need a new name because by 2030 there will be no glaciers left in the whole park. The great Greenland icecaps are melting at an alarming pace, and sliding into the sea. Your right, who cares it's not like its happening near us. But by 2100 all our coastal states will look like Venice including ours. You won?t be alive but your children and grandchildren will. The sea level is expected to rise up to 23 inches in the next decade. There has been a 100 percent increase in intensity and duration of hurricanes and tropical storms since 1970 according to a 2005 MIT study. How much more evidence do we need before someone does something about this? For anyone who cares at all about the future, the gradual transformation of our earth is turning into a human-furnace that makes terrorism look like a game of monopoly. Think I'm kidding? By 2050, 15-37% of all plant and animal species could be extinct. Meaning it will be harder for plants to produce photosynthesis. No big right? Wrong. Without photosynthesis, oxygen can?t be made. Most of us in this room will be in our late 60?s by then with children and grandchildren. What does that mean for them? The air will be harder to breath and the temperature of earth will have increased by 2 degrees Fahrenheit. By 2050 up to 38% of water will be unable to hold underwater species because of rising temperature.
Global warming is a major factor that has to be solved before all the effects begin to occur and it is too late to help.
