Veronica Torres Mr. Bontrager October 26th, 2012 The Great Climate Flip-Flop= In todays society people do not know what global warming really is. People think all over the world that global warming is worse than it is, or not really important. According to www.merriam-webster.com, “Global Warming is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons and other pollutants. ” Through many years of research, it has been proven that this has been around for many years and it has been effecting us in a lot of different ways. William H. Calvin, PH.D, has published a book about his studies and his research that he has observed in the past years.
Life has altered the atmosphere by releasing high levels of carbon dioxide along with other chemicals which has been slowly thinning the atmosphere over the years, 3. Why is the rotation of Venus different from that of Earth? All the planets in the solar systems rotate counter clockwise around the sun except Venus. Venus rotates clockwise or retrograde around the sun. Venus also has the slowest rotation out of all the planets rotating around the sun every 243 Earth days.
Sunspots can be quite small ([IMAGE]1500 km diameter), and reach sizes up to 50000 km. While it is known that the darker appearance of the umbra and penumbra is due to their lower temperatures, the sharpness of the boundaries between the umbra and penumbra, and between the penumbra and photosphere, is a phenomenon that is not yet properly understood. While sunspots, especially large ones, can be fairly long-lived (their lifetimes being measured in weeks and months), they do eventually disappear, often by successive fragmentation into smaller and smaller sunspots. Likewise, sunspots do not suddenly appear fully grown, but usually show up as small structures, irregularly shaped and usually without a penumbra (darker structures without penumbra are
Plate tectonics and Associated hazards Analyse the factors that cause differences in the hazards posed by volcanoes around the world. (40 Marks) Using case studies we can clearly see the differences in the hazards that volcanoes pose. A hazard is a situation that poses a level of threat to life, health, property or environment. The level of hazard posed by different volcanoes can very greatly, from a weak eruption with minimal impact that causes little damage, to a violent and life threatening explosion. Most of the sixty-plus volcanoes that erupt each year are low risk, however a combination of factors can cause a volcano to be a serious hazard.
The government has spent 10 billion dollars on the Yucca Mountain project already so it would be a waste to not use it, don’t we want our tax dollars to be well spent? We should use Yucca Mountain to dispose of our nuclear waste. If we do not dispose of the waste soon then perhaps, a leak could occur in a nuclear waste container and it would do damage to our country. We would not want that. With the design of the steel barriers that would contain the repository, which is similar to a big steel box, the site would be good for thousands of years to come.
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.
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.
Should Australia go Nuclear? Unless you live under a stone, you’ll be aware that we have a very serious problem with global warming, most of which occurs because of the burning of fossil fuels like coal to produce energy. As a result of these concerns, there is a really important debate currently underway about what kind of energy Australia should have in the future, fossil fuel, renewable energy or nuclear? Nuclear energy was on the discussion table a few years ago but recently it has surfaced again due to global warming. One of the greatest advantages of nuclear power is that it avoids the wide variety of environmental problems arising from burning fossil fuels such as coal, gas and oil.
Not just one area but globally! That would give us a better indication of global warming. Artic sea ice is another thing we should be monitoring. “September Arctic sea ice is now declining at a rate of 11.5 percent per decade, relative to the 1979 to 2000 average” (Global Climate Change: Key Indicators, 2014). Due to, again warmer temperatures both maximum and minimum we are seeing ice melt.
The Globe is losing its Cool Global Warming Melissa Moran University of Phoenix Axia collage Professors name SCI 275 October 21, 2009 There are many reasons for the change in the climate. Climate change also known as global warming is the change in the average temperature of the earth surface, and the change in wind and precipitation. Global warming is caused by releasing fossil fuels into the atmosphere. Many factors such as human activity and greenhouse gas emissions contribute to global warming. Global warming also has natural causes though they are often down-played in the media.
