global warming?

Nope: The world stopped getting warmer almost 16 years ago, according to new data released last week. The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures.This means that the ‘plateau’ or ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years.

Global warming

Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.^[2] Warming of the climate system is unequivocal, and scientists are more than 90% certain that it is primarily caused by increasing concentrations of greenhouse gases produced by human activities such as the burning of fossil fuels and deforestation.^[3][4][5][6] These findings are recognized by the national science academies of all major industrialized nations.^[7][A]Climate model projections were summarized in the 2007 Fourth Assessment Report (AR4) by the Intergovernmental Panel on Climate Change (IPCC). They indicated that during the 21st century the global surface temperature is likely to rise a further 1.1 to 2.9 °C (2 to 5.2 °F) for their lowest emissions scenario and 2.4 to 6.4 °C (4.3 to 11.5 °F) for their highest.^[8] The ranges of these estimates arise from the use of models with differing sensitivity to greenhouse gas concentrations.^[9][10]
(According to AR4) warming and related changes will vary from region to region around the globe.^[11] The effects of an increase in global temperature include a rise in sea levels and a change in the amount and pattern of precipitation, as well a probable expansion of subtropical deserts.^[12] Warming is expected to be strongest in the Arctic and would be associated with the continuing retreat of glaciers, permafrost and sea ice. Other likely effects of the warming include a more frequent occurrence of extreme-weather events including heat waves, droughts and heavy rainfall, ocean acidification and species extinctions due to shifting temperature regimes. Effects significant to humans include the threat to food security from decreasing crop yields^[13] and the loss of habitat from inundation.

Proposed policy responses to global warming include mitigation by emissions reduction, adaptation to its effects, and possible future geoengineering. Most countries are parties to the United Nations Framework Convention on Climate Change (UNFCCC),^[14] whose ultimate objective is to prevent dangerous anthropogenic (i.e., human-induced) climate change.^[15] Parties to the UNFCCC have adopted a range of policies designed to reduce greenhouse gas emissions^{[16]:10[17][18][19]:9} and to assist in adaptation to global warming.^{[16]:13[19]:10[20][21]} Parties to the UNFCCC have agreed that deep cuts in emissions are required,^[22] and that future global warming should be limited to below 2.0 °C (3.6 °F) relative to the pre-industrial level.^[22][B] A 2011 report of analyses by the United Nations Environment Programme^[23] and the International Energy Agency^[24] suggests that efforts as of the early 21st century to reduce emissions may be inadequate to meet the UNFCCC's 2 °C target.

The Effects of Global Warmning - Hot Sun

The Biggest Effect of Global Warming is Caused By The Sun

The Sun is the Main Cause of Global Warming?

Most people think that Effects of Global Warming that we see today is caused by Humans alone. This is not true in my view. The problem that Carbon di Oxide causes is that it does not allow the sun's radiation already received by the earth to be radiated back as CO2 traps it in the earth's atmosphere and heats it up.

But why is that people are not bothered about the sun itself?

The sun is slowly growing into a large red giant. it will continue to grow. Scientists and Astronomers have already predicted that in 2012 the some thing drastic will happen on the sun. The sun will emit loads and loads of rays and radiation that will disrupt all the radio, radar, mobile, power grids and all other communication networks including all our satellites.

We Have To Move Away From The Sun.

As the sun grows in size, its heat and other radiations will also increase. This means global warming problem will increase many folds. All the earth's ice will melt because of the Effect of Global Warming. The water in the sea will rise by more than 260 feet. That is not the end. We may also get fried on earth because of the sun's intense heat. So we have to move away from the Sun.

How Do We Move The Earth Away From The Sun?

NASA is already working out a plan. They will send a high speed satellite with adequate mass. This satellite will hit a carefully chosen meteorite whose path is likely to be close to earth or moon. By hitting the satellite, its path will alter very little and it will come closer to the moon, may be 10000 kilometers. Any thing closer it will hit the moon which they don't want to happen. The meteorite and moon will exert gravitational force on each other.

Using Moon We Will Move The Earth Away From The Sun

Once the moon moves outwards from its original orbit, it will cause a change in the earths orbit also. The calculations by NASA is such that the earth will get pulled by the moon and will start going away from the sun slowly about 3 cm every year. it is small amount but finally we will accelerate away and remain in such an orbit that as the Sun grows in size and heat, the earth will continue to remain in the same habitable cooler orbit.

Will The Earth Move as NASA is Planning?

This is not just theory. NASA will be able to move the earth to keep it cool. They have been sending satellites for a long time and humans have gone to space and moon. So I think we can believe what they say. Wait and Watch.

The Earth Will Blackout in 2013

Not the Effect of Global Warming ?

It is said that the earth is going to blackout in 2013. This is not an Effect of Global Warming or an Earth Quake or any Volcano eruption. Watch the Video below.




It will be like a scene where mobile phones go on the blink, GPS is knocked out, TVs go blank and the world is plunged into chaos. It is being caused a large unprecedented solar storm, which is essentially violent eruptions in the sun, can eject destructive radiation and charged particles into space. Looks like disaster flicks aren’t too removed from reality since all this could well be the potential result of a gigantic solar storm, according to a new report by NASA. The report, a warning, says Earth and space are coming together in a way that’s new to human history .These are closely connected to magnetic fields – which are hazardous for satellites and space stations. High-tech systems are critical for life as we know it today. Everything that we depend on and take for granted – GPS navigation, air travel,  internet banking services (even your credit card transaction needs a satellite) and emergency radio communications – can all be knocked out by intense solar activity

To get an idea of scale, a massive solar storm could result in 20 times more damage than the devastation caused by Hurricane Katrina which hit south-eastern US in August 2005. The storm killed 1,800 people and caused damages worth $81 billion. There are reports of a geomagnetic storm sparked by a huge solar flare that swept over the Earth in 1859. Telegraph wires shorted out and set houses on fire. A brilliant aurora was seen in Hawaii—so bright that  “people could read newspapers by [its] red and green glow.” Scientists predict  that in May 2013, the sun’s solar cycle will peak at about the same level as in 1859. (This content courtesy a post on Gawker.com)

Some good news is that some of the damage and destruction can be avoided with warning of an impending solar storm. There is technology to put satellites in ‘safe mode’ and disconnect transformers to protect them from destructive electrical surges. The key for Bogdan lies in NASA and NOAA collaborating. “NASA’s fleet of heliophysics research spacecraft provides us with up-to-the-minute information about what’s happening on the sun. They are an important complement to our own GOES and POES satellites, which focus more on the near-Earth environment.” The task of accurately forecasting a solar storm lies with the National Oceanic and Atmospheric Administration (NOAA) of the US. “Space weather forecasting is still in its infancy, but we’re making rapid progress,” said Thomas Bogdan, director of NOAA’s Space Weather Prediction Center in Colorado.

Sun Greenhouse Effects Global Warming

Greenhouse Effects Global Warming

What is Greenhouse Effect?

When the ground is heated inside a green house or a glass roof house with plants inside, the suns heat absorbed by the ground is radiated back to the sky. But the glass allows some heat to radiate out but reflects back some part of this radiated heat keeping the glass house green and plants grow. This is called a green house effect as shown below

What is Greenhouse Effect on Atmosphere?

When the ground is heated by the sun, the heat absorbed by the ground is radiated back to the sky. But like the glass, the green house gases like Carbon di Oxide, Methane, Nitrous Oxide, Ozone and Water vapour stops some part of this radiated heat and reflect it back to the earth. This is called a green house effect on the earth's atmosphere as shown below

What is Enhanced Greenhouse Effect?

When the amount of greenhouse gases increase in the atmosphere then more heat gets reflected back and remains trapped on earth. This is called Enhanced Greenhouse Effect as shown below: -

Which Gas Causes Max Greenhouse Effect?

Carbondioxide causes the maximum Greenhouse effect on earth. CO2 accounts for 60% of the greenhouse effect caused by any gas. This is increased today because of the population growth, cutting of trees that reduce CO2 and by burning fuel by our vehicles, planes and ships which release CO2 into the atmosphere. 

Is There Greenhouse Effect on the Moon?

No. Greenhouse Gases like CO2 is not there in the moon and its atmosphere is too thin and cannot trap any heat on its surface. Thus there is no Greenhouse effect on the moon as shown below

How to Achieve Zero Greenhouse Effect?

Reduce burning fuel by using public transports, use carpooling, don't generate waste that decay and release methane, do not burn garbage that release CO2 into the atmosphere, Plant more trees that convert CO2 to Oxygen and stop cutting trees. Stop using paper that is made from trees and recycle paper, do not burn paper. Use Renewable sources of energy like wind, wave and solar energy.

Save the Earth. Save Mankind from Extinction

The Effects of Global Warming

The Effects of Global Warming There is no denying that Global Warming is going to wipe out humanity if the humans don't act in time. The rise in temperature may be just half a degree centigrade in ten years. But the ice is so sensitive to temperature that it starts to melt down in the Antarctica. This will cause sea level rise.

Documented Effects of Global Warming There are documented evidence video shows that over 7 billion tons of ice shelf in Antarctica just fell into the sea in a span of just 3 days.

Loss of Habitable Land - The Effects of Global Warming When the sea level rises by just one centimeter, the sea spill over the land and eats up over 300 feet of land on an average along the coasts of the world. How much land fill can the human beings do, how much barricades can the human beings make to stop the sea from encroaching the sea shores? The effects of Global Warming is yet to come.

Cow Farts causing Global Warming!?

Scientists and farmers around the world are debating a very serious subject at the moment. You may not know it, but cows are actually one of the rudest animals around. In fact, they burp and fart so often and in such huge figures that the methane they release may be an affecting part of global warming. Yes, they are really talking about farting and burping cows.
Why are scientists talking about this? Good question, let's start with the science behind passing gas. Farts and burps are essentially pockets of gas that get released from human and animal bodies. Some of it is created inside our bodies as we digest food and some is ingested, when we eat or talk. This mixture is not useful to us, so our bodies propel it out as best they can, “passing gas or flatulence.”
One of the gases found in farts and burps is methane. Certain amounts of methane in the atmosphere are normal. Right along with other greenhouse gases, methane collects in the sky and traps warm air around our planet. The problem starts when the layer of greenhouse gases is too thick and too much heat is shut in. This effect is called global warming my friends!
A report published in the state of California a while back declared that dairy cows in the area were producing almost 20 lbs of gas every year. That is a ridiculously large amount of gas. If that number is correct, it could mean that cow farts are causing more greenhouse gases than pollution from cars, since California has millions of cows.
Scientists around our globe have known for a long time that animal gases could be trouble. What they cannot agree on is how big of a problem it can actually be. Even if scientists manage to measure the size of the farts or burps, they then have to work out how much methane they contain. It is very hard to measure just how much methane an animal is burping and farting out.
A Swedish university has taken this matter very seriously and has been awarded close to $600,000 in support to research this occurrence. Jan Bertilsson of the Swedish University for Agricultural Sciences stated that 20 cows will be involved in the study.
By attaching special collars around the cow’s necks, they hope to calculate the amount of methane released with each burp depending on the kind of food they consume. Mind you this is only a study on burps not farts.
I am not a scientist or anything but it looks like if we want to make a real effort at slowing down our climate change, we simply can’t only go after the cows. It just doesn’t seem to me to be the only source of the problem. What does the rest of the planet think?

Cars and Global Warming

One of the most eye-opening conclusions of reports is that the vehicles we choose today will affect our lives for time to come. Astonishingly, the largest category of current on the road polluters is the small car. We ask ourselves why? Well, simply because there are so many of them on the road. Cars in and light trucks our nations are a huge supply of global warming pollution. United States automobiles emit more than 333 million tons of carbon dioxide (CO2) per year, which is more than 1/5 of the nation's total CO2 emissions.
Compared with the rest of the planet, American automobiles emissions are excessively high. With only five percent of the world's population and thirty percent of the world's automobiles, the United States put in forty eight percent of the world's automotive CO2 emissions.
Any true effort to battle global warming has to include cutting automobile emissions. Acting now is crucial to slowing global warming and reducing air pollution.
Americans don't all have to drive hybrids to make a change in our nation. And, while we support everyone to use different forms of transportation whenever it is possible, the certainty is that cars are a big part of our American ways of life.

We should be thinking to:
• Put public pressure on the automobile industry to maintain a comprehensive national global warming policy.
• Educate vehicle owners and drivers on what they can do to decrease emissions.
• Explore ways we Americans can do our part to progress fuel efficiency and cut global warming pollution from America's automobiles.
So, if we all did our part to decrease automobile emissions and if all of us purchased the most fuel efficient vehicles that met our needs, and if all of us found ways to drive a less, if all of us did our best to keep our vehicles maintained, and if all of us contributed in prioritizing global warming as a issue in our daily lives, we would considerably decrease global warming pollution from America's vehicles.

Second Cause of Global Warming

Chlorofluorocarbons were introduced to the world in the 1920s and are used in a range of industrial, commercial, and residential uses and is a big part of Global Warming. Chlorofluorocarbons, along with others like chlorine- and bromine-containing compounds, have been implicated in the boost of reduction of ozone in our planet’s stratosphere. This stuff is non-flammable, non-toxic, and non-reactive with other chemical composites. These nice safety characteristics make them useful as coolants in air conditioners and refrigerators, propellants for aerosol sprays, and blowing agents. Production and use of Chlorofluorocarbons increased as a demand by us humans for production of these common products.
It was not until 1973 that chlorine was found to be a catalytic agent in ozone devastation. Catalytic obliteration of ozone gets rid of the odd O2 species while leaving chlorine unchanged. We knew that this was potentially damaging to the ozone layer, but beyond question evidence of stratospheric ozone depletion was not exposed until 1984. An intricate situation of atmospheric dynamics, chemical reactions, and solar radiation, was found to explain the abnormal low levels of ozone during the polar springtime. Current missions to the Arctic areas show that related processes can occur in the northern hemisphere, but to a lesser level due to warmer temperatures. We as a nation have to do something soon before this climate change takes a real toll on our planet!

The Main Cause for Global Warming

We humans who think of ourselves as the most intelligent things on this planet are intentionally or unintentionally destroying our own surroundings. One of the chief causes for global warming can be accredited to the behaviors of humans. It took more than twenty years for the world to finally accept that we humans are causing global warming with the emission of greenhouse gases which include carbon dioxide, methane, nitrogen oxide etc. the gases have formed an effect of green house on the earth’s exterior which prevents the reflection of the sun’s rays and therefore causes the boost in temperature. The radical boost in the emission of carbon dioxide in the last 30 years caused by burning fossil fuels has been recognized as the major reason for the change of temperature in the atmosphere.



Carbon dioxide concentration in the air has amplified because of the emissions from power plants, airplanes, cars, industries etc. one more reason for it is deforestation. Forests have been reduced making way for cultivation, industries and cities. The vegetation was natural regulators of carbon dioxide that controlled its level’s in the atmosphere. Eighty percent or more of the worldwide energy claim is currently supplied by the fossil fuels oil, coal or gas. It will be unfeasible to find alternative sources, which could restore fossil fuels in the short or medium term. The energy demand is just too high.



Another subject is the non-renewable traits of fossil fuels. It took our planet millions of years to produce these resources, while we will have used them up in about the next few decades. Alone the lessening supply will not make it possible to carry on as usual for a longer time.

What Is Global Warming?

Definition of the Global warming is

the rise in the average temperature of the Earth's near-surface air and

oceans. OR It observed and projected increases in the average

temperature of Earth's atmosphere and oceans. OR 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.

Earth was formed about 4.5 billion years ago and its

temperature has changed through history.it has been warmer in the

past,and sometimes much colder. But it is the speed at which earth is

heating up that is alarming. For the first btime in history, humans,not

nature are the main cause of earth’s changing climate or as it is

commonly known as Global warming.

Ice Ages –

for long periods of times- called ice ages-earth’s surface was almost

completely covered with ice. Much of the ice was stored in

glaciers.

Fossile fuels - All living things use

and store carbon. Millions years ago ,when plants and animals died,some

were buried, crushed, and fossilized under ground.oil,coal,natural gas

formed from this fossilized remains-this is why this is called fossile

fuels.
When we burn the fossile fuels we are releasing the large

amounts of carbon into the atmosphere as part of the gas carbon

dioxide. It is released naturally such as volcanoes, but humans and

machines we use are produce more carbon dioxide than ever before.70% of

the world’s energy is generated by burning the fossile

fuels.

What causes Global warming? Is it part of a

natural cycle?

Global warming is due to the build up of

greenhouse gases in the atmosphere, which form one sort of blanket over

the Earth,which traps the heat which is normally escape the atmosphere.

The main greenhouse gas is carbon dioxide, this is emitted from the

burning of fossil fuels.When we burn the fuel,gases are released, or

emitted, into the atmosphere. Our gas emission have been on the rise

since last century. When people started burning coal in factories to

produce power. As emissions have increased, sohas earth’s

temperature

What is Greenhouse gases –

Greenhouse gases are those which absorb the heat from the sun and help

warm the planet, which makes it possible for the the plants and animals

to live. Most greenhouse gases are the natural part of the life. For

example, human breaths out small amount of the carbon dioxide into the

air. But some human activities have caused some gases to buld up too

much. Many scientist belives this increase in greenhouse gases causing

global warming.

Which are Greenhouse gases?-

Carbon dioxide makes up more than 99percent of the greenhouse gases in

earth’s atmosphere.The remaining 0.6 percent contains methane,nitrous

oxide,ozone and halocarbons.

The Greenhouse

effects –The Greenhouse effect is a natural process discovered

in 18th century.it has kept our planet warm enough to support life for

billions of years.but as the amount of greenhouse gases increases, more

heat is trapped in the atmosphere. The natural process has sped up and

earth is getting hotter.
Greenhouse effect is the result of

absorption of heat by some greenhouse gases in the atmosphere and re-

radiate downward some of that heat. Most common example of the

greenhouse gas is the water vapour which is abundantly available in the

atmosphere, carbon dioxide and other trace gases. Without this natural

greenhouse effect.
The temperature of the Earth would be about -18°C

instead of 14°C.The greenhouse effect is the process in which the

emission of infrared radiation by the atmosphere warms a planet's

surface. Solar energy,only about half of the sun’s energy makes it to

earth’s surface. The rest is bounced back or trapped by clouds and the

atmosphere itself.
