Large Valley in The Eastern Region
Nujiang River in the western part of Yunnan province, sources in Tibet Xizang ~. River water flowing fast in perlembahan winding mountain steep, very primitive more mysterious, very beautiful scenery, given the nickname as the Great Valley in the Eastern Region. Goto along the river flow upstream, where there is one of the most beautiful scenery, is one good place to enjoy a bend in the river flow Bingzhongluo unity, where the river flows Nujiang turned 360-degree turn angle, forming a miracle of natural scenery.
Mr Zhong Juyao is an amateur photographer, he has departed from the city of Shenzhen is driving his car suffered a month of time browsing around the Nujiang River basin, which has received not a few photos are very nice scenery. Here his work was published in part so she could become the unspeakable pleasure for you.

Nujiang river here turning 360 degrees angle bend in the river form a unity in the world.

From the stone inscriptions Bingzhongluo not far away, is a great place to see the bend in the river in the world unity.

Scared and Amazing Holes

Not only stunning, but of them actually make us afraid and realize how small we are.

1. Kimberley Big Hole - South Africa

With a depth of 1097 meters, this is a mine producing 3 tons Diamond before finally closed in 1914

2. Diavik Mine, Canada

Looks more amazing when the surrounding water is frozen.

3. Mirny Diamond Mine , Serbia

Mines with a depth of 525 meters and a diameter of up to 1200 meters, and right above where the flight ban was imposed zones for aircraft.

4. Great Blue Hole , Belize

geography amazing phenomenon called a blue hole, located 60 miles from the main island of Belize.

5. Bingham Canyon Mine, Utah

This is the largest manmade hole in the earth, excavations began in 1863 and continued until now, until this moment has a depth of 3 / 4 miles and 2.5 miles wide.

Causes of Global Warming

2010-04-14T20:37:00.000-07:00

In the IPCC Fourth Assessment Report scientists conclude that "warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level" and, furthermore, they conclude with "very high confidence (at least a 9 out of 10 chance of being correct) that the globally averaged net effect of human activities since 1750 has been one of warming" of the Earth's climate system.

Water in a boiling pot receives heat from an element or flame and loses heat via steam and radiative cooling.

As with every environmental variable, there are multiple factors that contribute to the "warmth" of the Earth. Humans measure warmth as temperature which is a measure of the amount of heat contained in a physical object. One can envision this concept by thinking of a pot on a stove. As heat is applied to the pot from a flame or heating element, the temperature of the pot will increase. But heat will also begin escaping the pot in the form of steam and also through radiative and convective cooling from the top and the sides of the pot. Eventually the rates of both heat loss (cooling) and heat gain (warming) may stabilize and the heat then contained within the pot at an instantaneous point of time would be reflected in an equilibrium temperature. This equilibrium temperature could be measured directly but it also could be calculated by determining all of the flux rates of heat entering (heating) and leaving (cooling) the pot.

One way that climate scientists look at the warmth of the Earth's climate system is to calculate the annual average temperature of the surface of the Earth using temperature measurements systematically collected throughout the year from thousands of land- and ocean-based weather and observation stations. The observed trends in the Earth's annual average temperature is one of the factors leading to the scientific conclusion that the Earth is now in a period of global warming.

In order to attempt to answer why the Earth is currently warming, scientists have conducted accountings of each of the fluxes of heat into (warming) and out of (cooling) the Earth's climate system. Since the measured data show that annual average temperatures of the Earth have been increasing in recent decades, the year-to-year annual flux of heat into the climate system must be greater than the annual flux of heat out of the system. By accounting for each of the fluxes of heat into and out of the system, scientists are able to assess which fluxes and processes are contributing to net annual warming of the Earth's surface. By conducting such accountings, scientists are able to quantify the influence that each natural and human factor has in altering the balance of incoming and outgoing energy in the Earth-atmosphere system and can calculate an index of the importance of each of the factor as a potential climate change mechanism. Each of the factors are called climate drivers and the relative impact or index of each factor's importance to climate change is called its radiative forcing.

In completing such an assessment, the IPCC has concluded with very high confidence that the globally averaged net effect of human activities since 1750 has been one of warming. The scientists found that the combined radiative forcing due to increases in carbon dioxide, methane, and nitrous oxide is the largest climate driver and its rate of increase during the industrial era is very likely to have been unprecedented in more than 10,000 years. Furthermore, the carbon dioxide radiative forcing increased by 20% from 1995 to 2005, the largest change for any decade in at least the last 200 years.

The IPCC also found that anthropogenic contributions to aerosols in the atmosphere produce cooling effects, referred to as global dimming. However the cooling (global dimming) effects due to human-caused aerosols are equivalent to about half of the warming effects due to the combined radiative forcing of human-produced greenhouse gases, causing a net warming.

Significant anthropogenic contributions to radiative forcing were also found to have come from several other sources, including tropospheric ozone changes due to emissions of ozone-forming chemicals, direct radiative forcing due to changes in halocarbons, and changes in surface albedo, due to land-cover changes and deposition of black carbon aerosols on snow. However the impacts of each of these factors was relatively small compared to the impacts of anthropogenic greenhouse gases (each showing relative impacts of 15% or less relative to the greenhouse gas forcings).

Finally, an increase in solar irradiance since 1750 was estimated to have caused a forcing that contributed to the recent warming of the Earth. However, the impact of the increase in the amount of sunlight striking the Earth each year during this ~250 year time span was estimated to be only about 1/20th of the warming impacts of anthropogenic greenhouse gas emissions.

The Earth Day

2010-04-12T21:13:00.001-07:00

Earth Day is commemorated annually on 22 April, marks the anniversary of the birth of a change in environmental awareness movement in the 1970s. Born of Earth Day was initiated by a United States senator, Gaylord Nelson. At that time he was a national protest against the political circles related to environmental problems. He urged that these issues be included in the national agenda.

Gaylord Nelson struggle started around more than 7 years before the first Earth Day. Gaylord initially hoped his thinking is achieved through visits by President Kennedy to the 11 states in September 1963, but for some reason the visit was not able to bring environmental issues into the national agenda. Efforts continue to be Gaylord to realize his idea. After a tour of Kennedy, Gaylord conduct his own campaign to several states. Across the country, evidence of environmental degradation occurs everywhere. Everyone knew, except the political circles.

Finally in the summer of 1969 Gaylord know that the action of anti-Vietnam war demonstrations have spread widely through universities across the country. From there he got the idea to do the same thing in the campaign environment. He chose the lower ranks in protesting against environmental damage. At a conference in Seattle September 1969, Gaylord announced it would hold nationwide demonstrations in the spring of 1970 on behalf of the environment and everyone is invited to participate. After that, various letters, telegrams, and telephone flowing from around the country. Americans finally find a forum to express its concern over decline in soil quality, rivers, lakes, and air in their environment. On 30 November 1969 New York Times reported the increase in environmental awareness activities throughout the country especially on college campuses and one day for the memorial center is designed for environmental issues for the coming spring, which was coordinated by Senator Gaylord Nelson. This is a proof of the success of the struggle of Gaylord Nelson in promoting environmental issues as a national agenda.

On April 22, 1970, eventually about 20 million Americans took to the streets and meet the numerous parks and auditoriums to campaign for health and environmental sustainability. Thousands of students gathered against environmental damage. The groups have long opposed the presence of oil spills in the environment, factories and power plants causes pollution, poor sewerage, disposal of hazardous materials, pesticides, highways, loss of wilderness, wildlife extinction and also increasingly aware of togetherness for their struggle from the public.

Earth Day in 1970 has resulted in political circles that real unity is rare, coming from the republican and democrat, and a variety of mixing among others. The first Earth Day to the early formation of the United States Environmental Protection Agency / US EPA (a U.S. environmental protection agency) and also as a first step toward the environment with clean air and water, and protection of living things.

In 1990, Earth Day began to develop a global basis. Approximately 200 million people from 141 countries around the world moved to raise the issue of the environment on a global scale. Earth Day in 1990 became the starting point for implementation of the 1992 Earth Summit in Rio de Janeiro.

Earth Day 2000 received help with the internet to connect activists around the world. On April 22, around 5000 environmental groups around the world to embrace hundreds of millions of people in 184 countries that became new record for Earth Day which is celebrated on 22 April every year marks the anniversary of the birth of a change in awareness of the environment movement in 1970. Earth Day was born on the initiative of a United States senator, Gaylord Nelson. At that time he was a national protest against the political circles related to environmental problems. He urged that these issues be included in the national agenda.

Various activities carried out vary from drum chain from village to village in Gabon, Africa to the hundreds of thousands of people gathered on the National Mall, Washington DC, United States. Earth Day 2000 is called the message loudly and clearly that the population of the world wants a quick and decisive action for the use of clean energy and environmentally friendly.

In the year 2008, in order commemorate Earth Day, no matter if the people in this world must be "polite" to nature, could also be survival of mankind depend on "modesty" in our nature, we should be able to read and understand the cues . Global warming and food scarcity is one of the cues for humans so that we are "polite" to the outdoors, caring for the earth by way of giving "nutrition" on earth is one example.
