Global warming has been a giant issue in our world today the rising of seas, melting of ice caps, experiencing some of the worst natural disasters in centuries. We have known of this since 1980 to be exact. I've just got done reading two really good articles on global warming. Two articles that I read were Greenland Ice Cores: Frozen in time and the other article is named the Rising Seas . These two articles really informed me on whats happening in the world due to global warming.
Gore also asserts that global warming is caused by over population. Toxins and chemicals in the atmosphere impact each individual in the world. Because of the effects of global warming, the strength of hurricanes can change easily and cause an enormous amount of
Lately, global warming is threatening the entire polar bear population. Scientists warn that the rising temperatures will cause all of the summer sea ice that the bears depend on to vanish by 2040 (Polar bear SOS). Polar bears need that ice as a platform for hunting, travelling, mating, and for giving birth. When their ice melts, their food sources will decline and they will be forced to swim further to distant ice floes. During these journeys, many polar bears either drown or get lost.
These gases, with carbon dioxide being the main culprit, prevent solar heat from escaping the earth’s atmosphere, resulting in a rise in temperature, or the greenhouse effect. Already scientists around the world are detecting the numerous and dangerous effects of global warming (Johnson 18). Through these different leaks and spills our Canadian environment is slowly being negatively effected. The impacts of global warming on the Canadian environment are immense. Some of these impacts include ice bridges melting, and will have to be replaced with traditional building materials.
We should be concerned about this phenomenon because we never know when the climate may change again it may be cold one minute then next it may be so hot that it may be unbearable to stand. Crops getting destroyed, people falling over because of the heat wave. The word Flip-Flop is used to describe a climate change when it happens. Calvin claims that conditions in the North Atlantic Ocean are at the center of concern over climate flip-flop and here are the conditions and why they were caused and why were they dangers: If the climate switches then it can disrupt the food-supply routine and only two percent of the ninety-eight percent can eat. The system allows for a large urban population in the best of time, but not in the case of widespread disruptions.
If ice did not float, our planet would experience runaway freezing. Other properties of water include its solvency, cohesiveness, adhesiveness and other thermal properties. -EARTHS ATMOSPHERE- If there was too much of just one of the many gases which make up our atmosphere; our planet would suffer a runaway greenhouse effect. On the other hand, if there were not enough of these gases, life on this planet would be devastated by cosmic radiation. -EARTHS REFLECTIVITY- If Earths albedo was much greater than it is now we would experience runaway freezing.
Examples of these changes he mentions are the “Arctic ice cap is melting”, Greenland’s glaciers are “thinning”, the oceans are becoming more “acidic” and “warmer” which is lowering the survival rate of several species such as coral. A higher temperature in the earth’s oceans means “the greatest storms on our planet, hurricane and cyclones, have become more powerful.” (McKibben 12-45). This is what people need to take notice in because this is what will affect us humans in an extremely negative way. Yes chemical can be harming but changing our environment to what we depend on can cause
It needs to come to the end and the only ones that can stop this epidemic is “us”. Global warming may have disastrous results in the future as the glaciers may melt down thereby making the levels of the oceans to rise. If this is not checked, then it would lead to floods and cities along the coasts will be the worst affected. Whole cities would get submerged under the seas in the next 30 years. Research suggests that the effects of this warming are irreversible.
But if my opponents did any research, they would realize that there is plenty of evidence to show that global warming is a real threat to this earth. In his essay “Now Or Never”, Bill McKibben writes: Consider hydrology, for instance. Warm air holds more water vapor the cold air, so there is an increase in evaporation in dry areas, and hence more drought—something that has been documented on every continent. Once that water is in the atmosphere, it’s going to come down someone—and indeed we have seen the most dramatic flooding ever recorded in recent years. In 1998, 300 million humans, one in twenty of us, had to leave their homes for a week, and month, a year, forever because of rising waters.
Many worry about the negative consequences Global Warming may have on our Earth. It is believed that there will be detremental effects from sea to land. A rise in water levels causing the icecaps to melt. Melting icecaps would then release methane another greenhouse gas. The oceans salt water would mix with freshwater and CO2 would get absorbed into the oceans causing disabling effects on our waters food chain.
