Didn't I hear somewhere that NASA scientists have to submit their findings regarding global warming to The White House before they can be released?

And further, didn't I hear that said NASA scientists were furious to find that their reports had been edited to the extent that it actually changed the content of those reports to suit what the White House wanted to release to the public as opposed to what the documents actually said?

I'll have to do some research on that.

ABSTRACT A review of the research literature concerning
the environmental consequences of increased levels of atmospheric
carbon dioxide leads to the conclusion that increases during
the 20th Century have produced no deleterious effects upon
global weather, climate, or temperature. Increased carbon dioxide
has, however, markedly increased plant growth rates. Predictions
of harmful climatic effects due to future increases in
minor greenhouse gases like CO2 are in error and do not conform
to current experimental knowledge.
SUMMARY
World leaders gathered in Kyoto, Japan, in December 1997 to
consider a world treaty restricting emissions of ‘‘greenhouse gases,’’
chiefly carbon dioxide (CO2), that are thought to cause ‘‘global
warming’’ – severe increases in Earth’s atmospheric and surface
temperatures, with disastrous environmental consequences.
Predictions of global warming are based on computer climate
modeling, a branch of science still in its infancy. The empirical evidence
– actual measurements of Earth’s temperature – shows no
man-made warming trend. Indeed, over the past two decades, when
CO2 levels have been at their highest, global average temperatures
have actually cooled slightly.
To be sure, CO2 levels have increased substantially since the Industrial
Revolution, and are expected to continue doing so. It is reasonable
to believe that humans have been responsible for much of
this increase. But the effect on the environment is likely to be benign.
Greenhouse gases cause plant life, and the animal life that depends
upon it, to thrive. What mankind is doing is liberating carbon from
beneath the Earth’s surface and putting it into the atmosphere, where
it is available for conversion into living organisms.
RISE IN ATMOSPHERIC CARBON DIOXIDE
The concentration of CO2 in Earth’s atmosphere has increased
during the past century, as shown in figure 1 (1). The annual cycles in
figure 1 are the result of seasonal variations in plant use of carbon
dioxide. Solid horizontal lines show the levels that prevailed in 1900
and 1940 (2). The magnitude of this atmospheric increase during the
1980s was about 3 gigatons of carbon (Gt C) per year (3). Total human
CO2 emissions – primarily from use of coal, oil, and natural gas
and the production of cement – are currently about 5.5 GT C per year.
To put these figures in perspective, it is estimated that the atmosphere
contains 750 Gt C; the surface ocean contains 1,000 Gt C;
vegetation, soils, and detritus contain 2,200 Gt C; and the intermediate
and deep oceans contain 38,000 Gt C (3). Each year, the surface
ocean and atmosphere exchange an estimated 90 Gt C; vegetation
and the atmosphere, 60 Gt C; marine biota and the surface ocean, 50
Gt C; and the surface ocean and the intermediate and deep oceans,
100 Gt C (3).
So great are the magnitudes of these reservoirs, the rates of exchange
between them, and the uncertainties with which these numbers
are estimated that the source of the recent rise in atmospheric
carbon dioxide has not been determined with certainty (4). Atmospheric
concentrations of CO2 are reported to have varied widely over
geological time, with peaks, according to some estimates, some 20-
fold higher than at present and lows at approximately 18th-Century
levels (5).
The current increase in carbon dioxide follows a 300-year warming
trend: Surface and atmospheric temperatures have been recovering
from an unusually cold period known as the Little Ice Age. The
observed increases are of a magnitude that can, for example, be explained
by oceans giving off gases naturally as temperatures rise. Indeed,
recent carbon dioxide rises have shown a tendency to follow
rather than lead global temperature increases (6).
There is, however, a widely believed hypothesis that the 3 Gt C
per year rise in atmospheric carbon dioxide is the result of the 5.5 Gt C
per year release of carbon dioxide from human activities. This hypothesis
is reasonable, since the magnitudes of human release and atmospheric
rise are comparable, and the atmospheric rise has occurred
contemporaneously with the increase in production of CO2 from human
activities since the Industrial Revolution.

CARBON DIOXIDE

Carbon dioxide, CO2, is one of the gases in our atmosphere, being uniformly distributed over the earth's surface at a concentration of about 0.033% or 330 ppm. Commercially, CO2 finds uses as a refrigerant (dry ice is solid CO2), in beverage carbonation, and in fire extinguishers. In the United States, 10.89 billion pounds of carbon dioxide were produced by the chemical industry in 1995, ranking it 22nd on the list of top chemicals produced. Because the concentration of carbon dioxide in the atmosphere is low, it is not practical to obtain the gas by extracting it from air. Most commercial carbon dioxide is recovered as a by-product of other processes, such as the production of ethanol by fermentation and the manufacture of ammonia. Some CO2 is obtained from the combustion of coke or other carbon-containing fuels.

C(coke) + O2(g) CO2(g)

Carbon dioxide is released into our atmosphere when carbon-containing fossil fuels such as oil, natural gas, and coal are burned in air. As a result of the tremendous world-wide consumption of such fossil fuels, the amount of CO2 in the atmosphere has increased over the past century, now rising at a rate of about 1 ppm per year. Major changes in global climate could result from a continued increase in CO2 concentration.

In addition to being a component of the atmosphere, carbon dioxide also dissolves in the water of the oceans. At room temperature, the solubility of carbon dioxide is about 90 cm3 of CO2 per 100 mL of water. In aqueous solution, carbon dioxide exists in many forms. First, it simply dissolves.

CO2(g) CO2(aq)

Then, an equilibrium is established between the dissolved CO2 and H2CO3, carbonic acid.

CO2(aq) + H2O(l) H2CO3(aq)

Only about 1% of the dissolved CO2 exists as H2CO3. Carbonic acid is a weak acid which dissociates in two steps.

H2CO3 H+ + HCO3¯ Ka1 = 4.2 × 10¯7
HCO3¯ H+ + CO32¯ Ka2 = 4.8 × 10¯11

As carbon dioxide dissolves in sea water, an equilibrium is established involving the carbonate ion, CO32¯. The carbonate anion interacts with cations in seawater. According to the solubility rules, "all carbonates are insoluble except those of ammonium and Group IA elements." Therefore, the carbonate ions cause the precipitation of certain ions. For example, Ca2+ and Mg2+ ions precipitate from large bodies of water as carbonates. For CaCO3, the value of Ksp is 5 × 10¯9, and for MgCO3, Ksp is 2 × 10¯3. Extensive deposits of limestone (CaCO3) and dolomite (mixed CaCO3 and MgCO3) have been formed in this way. Calcium carbonate is also the main constituent of marble, chalk, pearls, coral reefs, and clam shells.

Although "insoluble" in water, calcium carbonate dissolves in acidic solutions. The carbonate ion behaves as a Brønsted base.

CaCO3(s) + 2 H+(aq) Ca2+(aq) + H2CO3(aq)

The aqueous carbonic acid dissociates, producing carbon dioxide gas.

H2CO3(aq) H2O(l) + CO2(g)

In nature, surface water often becomes acidic because atmospheric CO2 dissolves in it. This acidic water can dissolve limestone.

CO2(aq) + H2O(l) + CaCO3(s) Ca2+(aq) + 2 HCO3¯(aq)

This reaction occurs in three steps.

CaCO3(s) Ca2+(aq) + CO32¯(aq)
CO2(aq) + H2O(l) H2CO3(aq)
H2CO3(aq) + CO32¯(aq) 2 HCO3¯(aq)

In the third step, carbonate ions accept hydrogen ions from carbonic acid. This reaction often occurs underground, when rainwater saturated with CO2 seeps through a layer of limestone. As the water dissolves calcium carbonate, it forms openings in the limestone. Caves from which the limestone has been dissolved are often prevalent in areas where there are large deposits of CaCO3 (e.g., Mammoth Cave, Carlsbad Caverns, and Cave of the Mounds). If the water containing dissolved Ca(HCO3)2 reaches the ceiling of a cavern, the water will evaporate. As it evaporates, carbon dioxide escapes, and calcium carbonate deposits on the ceiling.

Ca2+(aq) + 2 HCO3(aq) H2O(g) + CO2(g) + CaCO3(s)

No wonder no one could explain what plants give off. I took chemistry, phsyics, and biology in college and its still not my expertise.

Thank you Kroika for the lesson!

Green plants convert carbon dioxide and water into food compounds, such as glucose, and oxygen. This process is called photosynthesis.

The reaction of photosynthesis is as follows:
6 CO2 + 6 H2O --> C6H12O6 + 6 O2

U.S. scientists have been pressured to make their writings on global warming fit with the Bush administration's skepticism on the topic, a U.S. Congressional committee has been told.

A survey by the Union of Concerned Scientists found 150 climate scientists had personally experienced political interference in their work over the past five years.

Worried Dad,

I see comments like this as such a breach of basic human decency, ethics, values, and reesponsibility on the most sacred subject of the value of human life. It must be very difficult to be a scientist in these days and ages. I'm sure most scientists went into the field with pure intentions and noble goals, and their value is reduced to being a pawn to government officials. Even intelligence and expertise is not valued, as commented on below.

Not surprising in a world where every researched intelligence report by experts who have a stake in presenting the truth is ignored, minimizing, or shoved in a file drawer, whether it be about the environment, 9-11, or the Iraq war.

What are we supposed to do as citizens of this country to make a difference here with such corruption at higher political levels and such a normalcy of denial on an national level. How many "natural" disasters, how many deaths, how much disease will it take for those in power to wake up??

gracenotes-
"What are we supposed to do as citizens of this country to make a difference here with such corruption at higher political levels and such a normalcy of denial on an national level. How many "natural" disasters, how many deaths, how much disease will it take for those in power to wake up??"

For one, we can start voting more wisely... and even then we have to make it clear that we wont tolerate (via boycotts, etc. anti-green corporations- which are what run this country anyway)... but that's an over simplified answer. My theory is that those in power are NOT ever going to wake up. Because despite what they say or how they spin it, they KNOW the truth. They don't believe their own arguements- those are for the ignorant masses they are trying to get to support them. What is real and true is not in question. What is given priority by those in power is the issue. The powers that be will always have an agenda that is slightly different from what they tell everyone it is. In most cases, it is not the best interest of the public or the general good that they care about- it is the desires and demands of a small elite few.

Civil rights for african americans, the vote for women, certain labor laws... none of these changed because the powers that be woke up. We can't wait for that. It's because a lot of people shook them from the foundations of our society.

It would be great to have hopes and faith in the powers that be. I just don't.

mzrella,

Good points! As with other things going on in the world, I am hoping that the extreme side of ignornance becomes so intolerable to so many that the public will start to really demand what it best for everyone environmentally and otherwise. I am thinking of the principle of how one can appreciate the light so more more if one has experienced the darkness.

I think this country is really going through the darkness on many issues, though the focus on the environmental ones are here, and it just cannot stay like this. I think too many people are going to be personally affected by so much of this that there will have to be a change in what politicians are going to need to value.

Meanwhile, I'm doing my small part with recycling responsibly and taking those small steps.

...don't forget the compact fluorescent lightbulbs!

Consider getting a smaller fridge. Request electricity consumption info on all appliances you buy.

Keep home heating below 20 C (George Monbiot recommends 18 C or 65 F) in winter.

Check environmental websites for more tips!

Oh, yes, and I just had new heating ducts put in my home. Well over 40 percent of the heat from the heater was being lost out of the heating ducts before it ever made it to the house. That will not only save heating and air-conditioning costs, but will help the environment.

Worried_Dad,

{Seeker,

Have you ever heard of Ronald Reagan, George W. Bush Sr., George W. Bush Jr. or any of his cabinet?

They have been death on the GW idea since sic em.

Why would the fossil fuel industry, fund the election of people who have become wealthy from fossil fuels?}

They've been opposed to GW idea because they've been resisting pressure from bureaucrats to jump on the "we have to save the world by regulating the crud out of the fossil fuel businesses" when there's no credible science to support the idea that people are a major contributor to GW. Reagan, Bush, etc. have represented the voice of reason.

My point seeker was to refute your statement:

"I can't recall hearing one politician say that they think humans aren't a major contributor to global warming. Quite the contrary."

And what is more, this administration has been caught "fudging the science" on this issue. If there is no credible scientific evidence then why do they feel the need to falsify the science?
