Global Warming (Finish): 2007

The people talks about global warming ---- Al Gore

Gore was one of the first politicians to grasp the seriousness of climate change and to call for a reduction in emissions of carbon dioxide and other greenhouses gases. He held the first congressional hearings on the subject in the late 1970s." During his tenure in Congress, Gore co-sponsored hearings on toxic waste in 1978–79, and hearings on global warming in the 1980s. In 1989, while still a Senator, Gore published an editorial in the Washington Post, in which he argued, "Humankind has suddenly entered into a brand new relationship with the planet Earth. The world's forests are being destroyed; an enormous hole is opening in the ozone layer. Living species are dying at an unprecedented rate." On Earth Day 1994, Gore launched the GLOBE program, an education and science activity that, according to Forbes magazine, "made extensive use of the Internet to increase student awareness of their environment".
In the late 1990s, Gore strongly pushed for the passage of the Kyoto Prorocol, which called for reduction in greenhouse gas emissions. He was opposed by the Senate, which passed unanimously the Byrd-Hagel Resolution,which stated the sense of the Senate was that the United States should not be a signatory to an protocol that did not include binding targets and timetables for developing as well as industrialized nations or "would result in serious harm to the economy of the United States". On November 12,1998, Gore symbolically signed the protocol. Both Gore and Senator Joseph Lieberman indicated that the protocol would not be acted upon in the Senate until there was participation by the developing nations. The Clinton Administration never submitted the protocol to the Senate for ratification. Mr. Gore is the author of An Inconvenient Truth, a best-selling book on the threat of and solutions to global warming, and the subject of the movie of the same title, which has already become one of the top documentary films in history. His best-selling book Earth in the Balance: Ecology and the Human Spirit (1992). He led the Clinton-Gore Administration's efforts to protect the environment in a way that also strengthens the economy.

How people think about global warming

"In addressing climate change, China has a unique opportunity to assert its rising global leadership role, as well as moral authority."By George A. Akerlof.

The losses from failing to address global warming if it does occur are truly enormous. Even more serious, the effects are also irreversible. In contrast, the losses from addressing global warming, if it does not occur or if it is not very serious, are not enormous and the losses from addressing the problem are only very large. In addition, it seems that the likelihood of global warming with serious impacts on large segments of the planet seems now to be very high.

Economic theory gives a simple natural way to fight global warming, which is to have escalating taxes on carbon emissions. There is a simple reason why this is the ideal remedy : carbon emissions into the atmosphere constitute a nuisance to everybody on the planet.
People should be taxed to pay a penalty equal to the value of the nuisance that they cause. In this way people who value their emissions more than the nuisance they cause will make those emissions and they will pay the tax. People whose emissions are not valued as much as the nuisance they cause will curb them and will not pay the tax. Thus with such a tax, emissions will be curbed insofar as the nuisance they create exceeds their benefits.

The Congress-people were not willing to vote for this because they felt that the costs of supporting Kyoto were too high relative to the benefits. In a nutshell they were afraid that their constituents would rebel against the increases in the prices that would accompany reductions in carbon emissions called for in the Kyoto Accords.

Global Warming Testimony @ Congress

What occurred in past Ice Ages was that when the Ice retreated,the natural vegetation cycles follow.The vegetation created CO2.Thats a great point,thats why the CO2 levels have beenincreasing since the end of the Little Ice Age.After th mid 1800's ice retreated,vegetation grew and CO2 increased.That makes total sense to me.Thats the explanation of high CO2 levels today.

Solar Variability and Climate

Solar Variability is a natural cause it to change,Solar irradiance changes have been measured reliably by satellites for only 30 years. 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. But the Solar Variability change will not cause big change of the global temperature, and the sun have less bright it mean the minimum solar came,global warming jujst continue to occur.

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 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.

Global Warming Map

The Global Warming Hotspots map from that web site is about local consequences in the world, Africa, Asia, North America, South America, and so on. It show in 2001.
In this map it talks about Fingerprints and Harbingers. Fingerprints is direct manifestations of a widespread and long-term trend toward warmer global temperatures.
It contact with
1.Heat waves and periods of unusually warm weather
2.Ocean warming, sea-level rise and coastal flooding
3.Glaciers melting
4.Arctic and Antarctic warming
(These "Fingerprints" of climate change are indicated with yellow icons.)
The other one Harbingers is events that foreshadow the types of impacts likely to become more frequent and widespread with continued warming. It contact with
1.Spreading disease
2.Earlier spring arrival
3.Plant and animal range shifts and population changes
4.Coral reef bleaching
5.Downpours, heavy snowfalls, and flooding
6.Droughts and fires
(These "Fingerprints" of climate change are indicated with red icons.)

The solutions of global warming!

There have many solution that we can do today, the solution will reduce the amount heat-trapping gases comeout into the atmosphere, also we can reduce the fossil fuels ,protect threatened forests.

The solutions to climate change is time to use.If we start today we can tackle the problem. It is common sense.

-Fuel-efficient vehicles

-Renewable energy

-Protecting threatened forests

These common sense solutions won't only reduce global warming, many will save us money and create new business opportunities. Whatever the solutions exist now. we just need to insist let governement make them available.

Global Warming occur in the history

Global temperatures on both land and sea have increased by 0.75 °C (1.35 °F) relative to the period 1860–1900, according to the instrumental temperature record. This measured temperature increase is not significantly affected by the urban heat island effect. Since 1979, land temperatures have increased about twice as fast as ocean temperatures (0.25 °C per decade against 0.13 °C per decade). Temperatures in the lower troposphere have increased between 0.12 and 0.22 °C (0.22 and 0.4 °F) per decade since 1979, according to satellite temperature measurements. Temperature is believed to have been relatively stable over the one or two thousand years before 1850, with possibly regional fluctuations such as the Medieval Warm Period or the Little Ice Age.

Sea temperatures increase more slowly than those on land both because of the larger effective heat capacity of the oceans and because the ocean can lose heat by evaporation more readily than the land.Since the northern hemisphere has more land mass than the southern it warms faster; also there are extensive areas of seasonal snow cover subject to the snow-albedo feedback. Although more greenhouse gases are emitted in the northern than southern hemisphere this does not contribute to the asymmetry of warming as the major gases are essentially well-mixed between hemispheres.

Based on estimates by NASA's Goddard Institute for Space Studies, 2005 was the warmest year since reliable, widespread instrumental measurements became available in the late 1800s, exceeding the previous record set in 1998 by a few hundredths of a degree. Estimates prepared by the World Meteorological Organization and the Climatic Research Unit concluded that 2005 was the second warmest year, behind 1998.

Anthropogenic emissions of other pollutants—notably sulfate aerosols—can exert a cooling effect by increasing the reflection of incoming sunlight. This partially accounts for the cooling seen in the temperature record in the middle of the twentieth century, though the cooling may also be due in part to natural variability.

Paleoclimatologist William Ruddiman has argued that human influence on the global climate began around 8,000 years ago with the start of forest clearing to provide land for agriculture and 5,000 years ago with the start of Asian rice irrigation. Ruddiman's interpretation of the historical record, with respect to the methane data, has been disputed.

What we can do?

There are ways we can help cut greenhouse gases and help stop global warming. They are very simple things, but can make a different if everyone does them!

1. Re-cycle glass bottles, jars, newspapers and magazines and tin cans. Save them and take them to local re-cycling centres.
2.Re-use plastic shopping bags and envelopes.

3.Put a brick in a plastic bag into your toilet cistern, then the toilet will use less water each time you flush.

4.Use paper on both sides. Try and buy products that don't use much packaging.
5.Give unwanted gifts and clothes to a charity shop.
6.Only fill the kettle up with the amount of water you need to boil that time.
7.Don't leave the TV , video, or computer on standby.

8.If you get lift to school in a car, take your mates along for the ride.

9.Switch lights off when you're not in the room.

10.Get a clockwork mobile phone recharger.
11.Cycle to places!

12.Have showers instead of baths. http://news.bbc.co.uk/cbbcnews/hi/find_out/guides/world/global_warming/newsid_2794000/2794907.stm

What could happen if the global warming are occur!

If the earth gets hotter, some of the important changes could happen:

1.Water expands when it's heated and oceans absorb more heat than land, so sea levels would rise.

2.Sea levels would also rise due to the melting of the glaciers and sea ice.

3.Cities on coasts would flood.

4.Places that usually get lots of rain and snowfall might get hotter and drier.

5.Lakes and rivers could dry up.

6.There would be more droughts making hard to grow crops.

7.Less water would be available for drinking, showers and swimming pools.

8.Some plants and animals might become extinct because of the heat. 9.Hurricanes, tornadoes and other storms which are caused by changes in heat and water evaporation may get more common.

Global Warming was bad??????????

Global Warming can be good ,but sometime it will become bad when the extra greenhouse gases are made the blanket gets thicker and too much heat is kept in the earth's atmosphere.
The earth naturally warmed by rays from the sun ,the rays pass though the earth's atmosphere and reflected back out to the space again, keep the earth at the right temperature for plants, animals and humans to survive. The atmosphere made up of gaess, some call the "Greenhouse Gases". So some of the global warming was good, not that bad we know!!!!!

The greenhouse cause the global warming

Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapour, carbon dioxide (CO2), methane and ozone. Greenhouse gases are those gases that contribute to the greenhouse effect (see below). The largest contributing source of greenhouse gas is the burning of fossil fuels leading to the emission of carbon dioxide.

The greenhouse effect when sunlight reaches Earth's surface some is absorbed and warms the earth and most of the rest is radiated back to the atmosphere at a longer wavelength than the sun light. Some of these longer wavelengths are absorbed by greenhouse gases in the atmosphere before they are lost to space. The absorption of this longwave radiant energy warms the atmosphere. These greenhouse gases act like a mirror and reflect back to the Earth some of the heat energy which would otherwise be lost to space. The reflecting back of heat energy by the atmosphere is called the "greenhouse effect".

The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide CO2, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive. Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons.

Greenhouse gases in the atmosphere act like a mirror and reflect back to the Earth a part of the heat radiation, which would otherwise be lost to space. The higher the concentration of green house gases like carbon dioxide in the atmosphere, the more heat energy is being reflected back to the Earth. The emission of carbon dioxide into the environment mainly from burning of fossil fuels (oil, gas, petrol, kerosene, etc.) has been increased dramatically over the past 50 years, see graph below.

What is Global Warming?

Global Warming: Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities.

Global Warming is the big problem that we need to pay attendtion, it will damage the earth and cause a lots of problem. Some place may dissappear, so let's start to do something!
