My Opinion bout GW

I think, global warming is a sign for us, human beings, to be responsible in what we had done.

God had given us power over all the plants and animals so that we can have a good life. God also wants us to take a good care of them, not making it worse.

We have to stop blaming each other! We have to realize that WE ARE THE CAUSE OF GLOBAL WARMING! We have to be responsible for it. Global Warming is not a small matter! Act now, do not postpone it!

Give what you can give, and do waht you can really do! It's our duty to take care of the earth. If it's not us, who else?

It's like Sekolah Mutiara Nusantara's theme for this year!

TOGETHER WE ARE STRONG

Global Warming through Times

• Global temperature changes from past millennia, according to available data, were often severe and rapid, long before man supposedly had any impact at all. That is, the current climate change is not as unusual as some alarmists would like to believe.

• Recent recorded history mentions times of noticeable global warming and cooling, long before man had any ability to produce industrial emissions.

• Water vapor, not CO2, is the most influential greenhouse gas. It is difficult to determine what effect, if any, mankind has on worldwide water vapor levels.

• Given the small percentage of human-produced CO2, as compared to other greenhouse gases, human impact on global temperature may be as little as 1%.

• Global temperatures are known to be influenced by other, non-human-controlled factors, such as sunspot activity, orbital movement, volcanic activity, solar system effects, and so forth. CO2 emission is not the only plausible explanation for global warming.

• Ice-age temperature studies, although rough, frequently show temperatures changing before CO2 levels, not after. This calls into question the relationship between warming and carbon dioxide; in some cases, the data could easily be interpreted to indicate that warming caused an increase in carbon dioxide, rather than the reverse!

• Computer simulations used to “predict” or “demonstrate” global warming require the assumption of human causation, and even then are not typically repeatable or reliable. Current computer weather simulations are neither predictive nor repeatable.

• Most of the global temperature increase of the last 100 years occurred before most of the man-made CO2 was produced.• In the 1970’s, global temperatures had actually been dropping since 1945, and a “global cooling” concern became prominent, despite what is now dismissed as a lack of scientific support.

• The “consensus” claimed by most global warming theorists is not scientific proof; rather, it is a statement of majority opinion. Scientific majorities have been wrongly influenced by politics and other factors in the past. Such agreement is not to be taken lightly, but it is not the same thing as hard proof

.• This “consensus,” as with many other scientific theories, can be partially explained by growing hostility to those with differing viewpoints, making it less likely that a person without preconceived notions would take on the subject for research. The financial and political ramifications of the global warming debate are too serious to be ignored, though they should not be central to any discussion.

• The data being used to support anthropogenic (man-caused) global warming is typically based on small data sets, single samples, or measurements taken in completely different regions. This creates an uncertainty in the results that rarely gets the attention that alarmist conclusions do.

Global Warming in Christianity

As Christians, we should be concerned about our effect on our environment. God appointed man to be the steward of this world (Genesis 1:28), not the destroyer of it. However, we should not allow environmentalism to become a form of idolatry, where the “rights” of an inanimate planet and its non-human creatures are held in higher esteem than God (Romans 1:25) and man created in His image. With global warming, as with any other topic, it is crucial to understand what the facts are, who those facts come from, how they are interpreted, and what the spiritual implications should be.

A careful look at global warming, as a topic, shows that there is a great deal of disagreement about the facts and substance of climate change. Those who blame man for climate change often disagree about what facts lead them to that conclusion. Those who hold man totally innocent of it often ignore established facts. Experience and research leads us to believe that warming is, in fact, occurring; however, there is little to no objective evidence that man is the cause, nor that the effects will be catastrophic. I think the idea of earth “wearing out” is an apt analogy. This entire world has been continually decaying since the fall.

Brief about Chlorofluorocarbons

Chlorofluorocarbons (CFCs), along with other chlorine- and bromine-containing compounds, have been implicated in the accelerated depletion of ozone in the Earth's stratosphere. CFCs were developed in the early 1930s and are used in a variety of industrial, commercial, and household applications. These substances are non-toxic, non-flammable, and non-reactive with other chemical compounds. These desirable safety characteristics, along with their stable thermodynamic properties, make them ideal for many applications--as coolants for commercial and home refrigeration units, aerosol propellants, electronic cleaning solvents, and blowing agents. Production and Use of Chlorofluorocarbons experienced nearly uninterrupted growth as demand for products requiring their use continued to rise.

Not until 1973 was chlorine found to be a catalytic agent in ozone destruction. Catalytic destruction of ozone removes the odd oxygen species [atomic oxygen (O) and ozone (O3)] while leaving chlorine unaffected. This process was known to be potentially damaging to the ozone layer, but conclusive evidence of stratospheric ozone loss was not discovered until 1984. Announcement of polar ozone depletion over Antarctica in March 1985 prompted scientific initiatives to discover the Ozone Depletion Processes, along with calls to freeze or diminish production of chlorinated fluorocarbons. A complex scenario of atmospheric dynamics, solar radiation, and chemical reactions was found to explain the anomalously low levels of ozone during the polar springtime. Recent expeditions to the Arctic regions show that similar processes can occur in the northern hemisphere, but to a somewhat lesser degree due to warmer temperatures and erratic dynamic patterns.

Replacement compounds for CFCs have also been evaluated for their Ozone Depletion Potential (ODP). Hydrochlorofluorocarbons (HCFCs) still contain chlorine atoms, but the presence of hydrogen makes them reactive with chemical species in the troposphere. This greatly reduces the prospects of the chlorine reaching the stratosphere, as chlorine will be removed by chemical processes in the lower atmosphere. Hydrofluorocarbons (HFCs), potential replacements for CFCs that contain no chlorine, have been evaluated for potential effects of fluorine compounds on ozone destruction. McFarland and Kaye give an overview of the CFC-ozone issue in the 1992 paper "Chlorofluorocarbons and Ozone."

Fight Back

• The temperature effect of atmospheric carbon dioxide is logarithmic, not exponential.

• The potential planetary warming from a doubling of atmospheric carbon dioxide from pre-Industrial Revolution levels of ~280ppmv to 560ppmv (possible some time later this century - perhaps) is generally estimated at around 1 °C.

• The guesses of significantly larger warming are dependent on "feedback" (supplementary) mechanisms programmed into climate models. The existence of these "feedback" mechanisms is uncertain and the cumulative sign of which is unknown (they may add to warming from increased atmospheric carbon dioxide or, equally likely, might suppress it).

• The total warming since measurements have been attempted is thought to be about 0.6 degrees Centigrade. At least half of the estimated temperature increment occurred before 1950, prior to significant change in atmospheric carbon dioxide levels. Assuming the unlikely case that all the natural drivers of planetary temperature change ceased to operate at the time of measured atmospheric change then a 30% increment in atmospheric carbon dioxide caused about one-third of one degree temperature increment since and thus provides empirical support for less than one degree increment due to a doubling of atmospheric carbon dioxide.

• There is no linear relationship between atmospheric carbon dioxide change and global mean temperature or global mean temperature trend -- global mean temperature has both risen and fallen during the period atmospheric carbon dioxide has been rising.

• The natural world has tolerated greater than one-degree fluctuations in mean temperature during the relatively recent past and thus current changes are within the range of natural variation. (See, for example, ice core and sea surface temperature reconstructions.)

• Other anthropogenic effects are vastly more important, at least on local and regional scales.

• Fixation on atmospheric carbon dioxide is a distraction from these more important anthropogenic effects.

• Despite attempts to label atmospheric carbon dioxide a "pollutant" it is, in fact, an essential trace gas, the increasing abundance of which is a bonus for the bulk of the biosphere.

• There is no reason to believe that slightly lower temperatures are somehow preferable to slightly higher temperatures - there is no known "optimal" nor any known means of knowingly and predictably adjusting some sort of planetary thermostat.

• Fluctuations in atmospheric carbon dioxide are of little relevance in the short to medium term (although should levels fall too low it could prove problematic in the longer-term).

• Activists and zealots constantly shrilling over atmospheric carbon dioxide are misdirecting attention and effort from real and potentially addressable local, regional and planetary problems.

No to Plastic Bags!!

Just Say No to Plastic Bags
By Carolyn Sayre

The plastic bags you bring home from the supermarket probably end up in a landfill. Every year, more than 500 billion plastic bags are distributed, and less than 3% of those bags are recycled. They are typically made of polyethylene and can take up to 1,000 years to biodegrade in landfills that emit harmful greenhouse gases. Reducing your contribution to plastic-bag pollution is as simple as using a cloth bag (or one made of biodegradable plant-based materials) instead of wasting plastic ones. For your next trip to the grocery store, BYOB.

Global Waring : The Effects

As the concentration of greenhouse gases grows, more heat is trapped in the atmosphere and less escapes back into space. This increase in trapped heat changes the climate and alters weather patterns, which may hasten species extinction, influence the length of seasons, cause coastal flooding, and lead to more frequent and severe storms.

What causes Global Warming?

Greenhouse Gases and Global Warming

   

 While many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gases. By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases, because fewer trees means less carbon dioxide conversion to oxygen.



During the 150 years of the industrial age, the atmospheric concentration of carbon dioxide has increased by 31 percent. Over the same period, the level of atmospheric methane has risen by 151 percent, mostly from agricultural activities such as raising cattle and growing rice.

9 essential facts about global warming

1)The leading cause of global warming is from water vapor, then carbon dioxide emissions, nitrous oxides, and chlorofluorocarbons (used in household appliances like air conditioning ).

2)Chlorofluorocarbons are expected to be eliminated and put out of use by 2030 to help slow down global warming.

3)The biggest business sectors that are contributing to global warming are the following: Industry, Transportation, Residential, Commercial, Agriculture.

4)Methane is the second biggest cause of greenhouse warming. Gas from cows is a big contributor to global warming.

5)A big enough volcano eruption could cool the earth for one or two years because sulfuric acid from the explosion would combine with water vapor to form a “shield” that would reflect some sunlight away from earth. Such an eruption would be quite catastrophic, though.

6)The coloration of aerosols (miniscule particles in the air) generally changes their relationship with the sun. Lightly colored aerosols reflect light back away from earth (as a white t-shirt) while darker aerosols generally absorb heat (as a hot asphalt road when it is sunny).

7)Generally, wispy clouds, such as cirrus clouds, trap light and thus warm the atmosphere whilst thick clouds generally reflect sunlight.

8)Ice/snow cover cools the earth by reflecting sunlight.

9)Without water vapor's effect on the atmosphere, the earth would be at below freezing temperatures.

-Global Warming- is it happening?

Is It Happening?

Yes. Earth is already showing many signs of worldwide climate change.

• Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.

•The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.

• The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.

• Arctic ice is rapidly disappearing, and the region may have its first completely

ice-free summer by 2040 or earlier. Polar bears and indigenous cultures

are already suffering from the sea-ice loss.

• Glaciers and mountain snows are rapidly melting—for example, Montana's Glacier National Park now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later.

• Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching—or die-off in response to stress—ever recorded in 1998, with some areas seeing bleach rates of 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise.

• An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts.

~CRY~

Rihanna

I'm not the type to get my heart broken

I'm not the type to get upset and cry'

cause I never leave my heart open

Never hurts me to say goodbye

Relationships don't get deep to me

Never got the whole in love thing

And someone can say they love me truly

But at the time it didn't mean a thing

[Chorus:]

My mind is gone, I'm spinning round

And deep inside, my tears I'll drown

I'm losing grip, what's happening

I stray from love, this is how I feel

This time was different

Felt like, I was just a victim

And it cut me like a knife

When you walked out of my life

Now I'm, in this condition

And I've, got all the symptoms

Of a girl with a broken heart

But no matter what you'll never see me cry

Did it happen when we first kissed?

'cause it's hurting me to let it go

Maybe 'cause we spent so much time

And I know that it's no more

I should've never let you hold me baby

Maybe why I'm sad to see us apart

I didn't give to you on purpose

Can't figure out how you stole my heart

[Chorus]

How did I get here with you, I'll never know?

I never meant to let it get so, personal

After all I tried to do, stay away from loving you

I'm broken hearted, I can't let you know

And I won't let it show

You won't see me cry

[x2]

This time was different

Felt like, I was just a victim

And it cut me like a knife

When you walked out of my life

Now I'm, in this condition

And I've, got all the symptoms

Of a girl with a broken heart

But no matter what you'll never see me cry

All my life...
