Globaly warming essay?

Question

I think global warming is an issue for our generation, I never thought about it until I watched the movie ‘Inconvenient Truth’. It made me believe what was going on in our world. The thing that made me really believe the most was when the statistics showed the pattern of co2 and temperature levels. To explain it more deeply, scientists have now proven that it is a fact that when ever the co2 rises so does the temperature. They have taken measurements for many years now. So this means because we are producing more co2 it is going to make the temperature rise more and more. For a long time the co2 lvls have been pretty consistent but in the last few years they have gone very high. This is caused by the amount of co2 we use today, if you think about it every one is using petrol cars and companies uses a lot of co2 as well to manfacture products etc. And we burn coal to use electricity so everything you use with electricity is harming the environment. There are a lot of problems with global warming, it is causing destruction across world. One thing that is happning which mite not seem as a big deal is that ice caps are melting. Normaly the ice caps reflect the heat but the water around it asorbs heat so because of the hotter weather the water is getting warmer making the icecaps melt. The hotter waters is a huge problem when there is a natural disaster like a hurricane because when ever a hurricane picks up strength depending on the warmth of the water. This is causing huge destruction, the scientists can predict what type the hurricane it is going to be but if it goes over warmer water that can all change. There is a big problem in Antarctica. Polar bears are drowning , trees are getting covered by water and soon dying, houses are destroyed because the ice underneath is melting. Greenland is getting warmer, it rose 16 degrees in the past decade!! There is also another very big problem, mosquitoes are breeding higher and spreading more diseases. Scientists thought that some diseases were gone but the mosquitoes are spreading them around again and even new diseases are coming. So now people have to come up with new vaccines, and the people in 3rd world countries will have less chance of surviving. The words most famous mountains have changed you look back pictures of it 200 years ago and look now it is a lot different. There is a lot of things we can do to use less co2 scientests are getting busy making elictricty from things other than coal such as solar power, wind power

Answer 1

Global warming -- a gradual increase in planet-wide temperatures -- is now well documented and accepted by scientists as fact. A panel convened by the U.S National Research Council, the nation's premier science policy body, in June 2006 voiced a "high level of confidence" that Earth is the hottest it has been in at least 400 years, and possibly even the last 2,000 years. Studies indicate that the average global surface temperature has increased by approximately 0.5-1.0°F (0.3-0.6°C) over the last century. This is the largest increase in surface temperature in the last 1,000 years and scientists are predicting an even greater increase over this century. This warming is largely attributed to the increase of greenhouse gases (primarily carbon dioxide and methane) in the Earth's upper atmosphere caused by human burning of fossil fuels, industrial, farming, and deforestation activities.

Average global temperatures may increase by 1.4-5.8ºC (that's 2.5 - 10.4º F) by the end of the 21st century. Although the numbers sound small, they can trigger significant changes in climate. (The difference between global temperatures during an Ice Age and an ice-free period is only about 5ºC.) Besides resulting in more hot days, many scientists believe an increase in temperatures may lead to changes in precipitation and weather patterns. Warmer ocean water may result in more intense and frequent tropical storms and hurricanes. Sea levels are also expected to increase by 0.09 - 0.88 m. in the next century, mainly from melting glaciers and expanding seawater . Global warming may also affect wildlife and species that cannot survive in warmer environments may become extinct. Finally, human health is also at stake, as global warming may result in the spreading of certain diseases such as malaria, the flooding of major cities, a greater risk of heat stroke for individuals, and poor air quality.

Climate change is very likely having an impact now on our planet and its life, according to the latest installment of a report published by the Intergovernmental Panel on Climate Change (IPCC). And the future problems caused by rising seas, growing deserts, and more frequent droughts all look set to affect the developing world more than rich countries, they add. The report is the second chapter of the IPCC's Fourth Assessment -- the most comprehensive summary yet of research into the causes and effects of climate change.

Factors

Greenhouse Gases

The increase in greenhouse gases caused by human activity is often cited as one of the major causes of global warming. These greenhouse gases reabsorb heat reflected from the Earth's surface, thus trapping the heat in our atmosphere. This natural process is essential for life on Earth because it plays an important role in regulating the Earth's temperature. However, over the last several hundred years, humans have been artificially increasing the concentration of these gases, mainly carbon dioxide and methane in the Earth's atmosphere. These gases build up and prevent additional thermal radiation from leaving the Earth, thereby trapping excess heat.

Solar Variability & Global Warming

Some uncertainty remains about the role of natural variations in causing climate change. Solar variability certainly plays a minor role, but it looks like only a quarter of the recent variations can be attributed to the Sun. At most. During the initial discovery period of global warming, the magnitude of the influence of increased activity on the Sun was not well determined.

Solar irradiance changes have been measured reliably by satellites for only 30 years. These precise observations show changes of a few tenths of a percent that depend on the level of activity in the 11-year solar cycle. Changes over longer periods must be inferred from other sources. Estimates of earlier variations are important for calibrating the climate models. While a component of recent global warming may have been caused by the increased solar activity of the last solar cycle, that component was very small compared to the effects of additional greenhouse gases. According to a NASA Goddard Institute for Space Studies (GISS) press release, "...the solar increases do not have the ability to cause large global temperature increases...greenhouse gases are indeed playing the dominant role..." The Sun is once again less bright as we approach solar minimum, yet global warming continues.

GLOBAL WARMING HAS TO STOP BEFORE WE ALL DIE.

HUMANS MADE THIS MESS AND HUMANS ARE THE ONLY ONES WHO CAN CLEAN IT UP!

Answer 2

im assuming this is your essay so ill just give you a few pointers.

===========

"It made me believe what was going on in our world."

sounds funny did you not believe what was in the world before? maybe try aware of what was going on in the world.

===============

the thing about the CO2 and temp coralation is alot more complex (they both feed off each other)  but that should be fine.

================

For a long time the co2 lvls have been pretty consistent but in the last few years they have gone very high

CO2 began rising at the start of the indusreial revalushion. putting a graph and some facts in here would be good (eg CO2 levels have risen by X in Y years)

=================

you tend to talk about small things like polar bares without expanding. why should i care if they die? what effect will that have on other animals and plants?

FYI Polar bears are not drowning. the bears gore refers to actuly drouned in a storm. the main danger is if the sea ice melts polar bears will not be able to hunt seals and will starve.

================

you say that mountans have changed how have they changed.  maybe include some pictts.

Answer 3

You're absolutely right.  This is a pretty good essay.  Stick with it.  Stay in school.  Don't listen to the disinformation artists who want to tell you that you're wrong.  You are right, and they are wrong (or lying).

Answer 4

The Book “An Inconvenient Truth” was written by a pure politician for purely political gain and has absolutely no basis in fact, except that he is taking advantage of natural climate cycles to yell “The Sky is Falling”

Considering 80% of our impending climate change is due to natural solar cycles and Earth orbit eccentricities (proven by Mackovich Earth orbit and Vostok ice core studies), and it has taken over 200 years of industrial pollution to create our share of it (about 20%)… no short term action will have any immediate effect.  In theory, if we immediately stopped using Co2 producing energy sources, we could expect to see a reversal of our contribution (that’s only 20% remember) to climate change within 100 to 150 years.  

I will remind you of the Chicken Little’s a few years back that forecast an end to life on earth if we didn’t do something about the ozone holes at the poles… we stopped using flouocarbon aerosols in spray-cans (a decidedly symbolic gesture) and voila, the ozone hole problem was solved (but the ozone holes are still there, unchanged, because they are now known to be a natural phenomenon due to the earths fluctuating magnetic field).    

The interesting part of this climate change scenario is the total lack of any meaningful action.  Predictions are grim, we could be facing global extinction of Homo Sapiens within 200-500 years, but all the politicians are doing is jockeying for power.  

The truth is, if we immediately cut back fossil fuel use world wide by 10% it would plunge the world into political chaos, millions starving in the first few years.  It was studied years ago what would be the outcome if the population of China added one egg a day to their diet.  The answer surprised most people…. To add one egg a day, the additional number of chickens would consume all the grain currently produced daily, worldwide.  Back to the drawing board… There is NO simple answer.

Answer 5

For the most part you look like that this is the first time you have seen this. But we are in even bigger problems. Humans have produced over half of the worlds oil-peak oil. As for CO2 it lags the temperature increase by about 500 years. Most of our heating is coming from burning 100 million barrels of oil plus coal, nuclear, and natural gas each day. Desertification is our big picture problem, we have destroyed half of the rain forests, half of the grasslands, and half of the wetlands-these control the surface temperature. See coolingearth.org for more information.

Answer 6

Man made global warming is a MYTH.  More CO2 means that we will have more plant life.  There are more trees in America now than there was 200 years ago. Also on CO2, man produces 3% the other 97% comes from mother Earth. What Al Gore is preaching is global socialism.  You really need to go to the library and check out some books.  Here are a few:

1-Hard Green: Saving the Environment from the Environmentalist by Peter Huber.  2-Eco Imperalism: Green Power, Black Death by Paul Driessen.  3-Meltdown: The predictable Distoration of Global Warming by Politicians, Science and the Media by Patrick J. Micheals.  4-The Politically Incorrect Guide to Global Warming and Environmentalism by Christoper C. Horner.  Lastly, the Earth has been going through changes for billions of years. How long has man been around?  Do not buy into the hype, do your own research.  Man is not that arrogant.

Answer 7

William Gray, the well-known Colorado State University hurricane forecaster, routinely uses the annual National Hurricane Conference as a platform to bash global warming. In a statement to Florida Today, Gray argued that the scientific consensus on global warming is bogus — and "a mild form of McCarthyism has developed toward those scientists who do not agree" that mankind is in danger.

"We are also brainwashing our children on the warming topic. We have no better example than Al Gore's alarmists and inaccurate movie which is being shown in our schools and being hawked by warming activists with little or no meteorological-climate background," Gray wrote.

Some scientists believe global warming will actually decrease — not increase — the number of hurricanes that form over the Atlantic Ocean each year. Last Friday, in the final session of the hurricane conference, a pair of climate experts said rising sea-surface temperatures in and near the Caribbean could strengthen vertical wind shear. Robust wind shear is the bane of hurricanes, as it tends to tear apart cyclones during their formative stages.

"If (global warming) were to happen, that is an effect which should be more hostile to hurricane building," said Thomas Knutson, research meteorologist with the Geophysical Fluid Dynamics Laboratory in Princeton, N.J.

Knutson and Chris Landsea, science and operations officer with the National Hurricane Center in Miami, said historic observation data and computer models debunk doomsday scenarios that foresee armadas of deadly hurricanes, slamming into the Southeast. "Any (hurricane) trend we're seeing due to global warming — and I do agree global warming's real, and manmade causes contribute to it — really has very limited impact, very tiny changes," Landsea said.

Both scientists referred to the global warming studies of ocean climatologist Kerry Emanuel of the Massachusetts Institute of Technology. Emanuel noted that from 1972-2004, Atlantic surface temperatures and hurricane intensity were closely linked.

Answer 8

Here is truth about global warming:

Global warming is one-half of the climatic cycle of warming and cooling.

The earth's mean temperature cycles around the freezing point of water.

This is a completely natural phenomenon which has been going on since there has been water on this planet. It is driven by the sun.

Our planet is currently emerging from a 'mini ice age', so is

becoming warmer and may return to the point at which Greenland is again usable as farmland (as it has been in recorded history).

As the polar ice caps decrease, the amount of fresh water mixing with oceanic water will slow and perhaps stop the thermohaline cycle (the oceanic heat 'conveyor' which, among other things, keeps the U.S. east coast warm).

When this cycle slows/stops, the planet will cool again and begin to enter another ice age.

It's been happening for millions of years.

The worrisome and brutal predictions of drastic climate effects are based on computer models, NOT CLIMATE HISTORY.

As you probably know, computer models are not the most reliable of sources, especially when used to 'predict' chaotic systems such as weather.

Global warming/cooling, AKA 'climate change':

Humans did not cause it.

Humans cannot stop it.
