aerosols and greenhouse gas interaction
“Recently, Shindell and his colleagues modified a NASA
climate model to consider chemical reactions among major atmospheric
constituents and the resulting effect on aerosol concentration.
Their report, in the Oct. 29 Science, reveals that some greenhouse
gases have a substantially stronger warming effect than previously
recognized because they take part in reactions that destroy
aerosols, while others actually tend to boost concentrations
of cooling aerosols.”
—
“New portions of the revised model consider the
influence of methane, carbon monoxide and nitrogen oxides
on the atmospheric concentration of hydroxyl radicals,
highly reactive molecules sometimes referred to as the
atmosphere’s detergent. Hydroxyl concentrations
can be depleted as these radicals react with gases in
the atmosphere [or increased
in the case of nitrogen oxides- ed.], and this
slows the reactions that produce light-colored, light-scattering
sulfate aerosols, Shindell says. “And a lower
number of aerosols means a lower cooling effect,”
he notes.”
—
“ ...Recent studies have found that as much as
20 percent of the warming in Europe since the 1970s
stems from a decline in aerosols, such as fog and haze,
during that period.” [Quoted from sciencenews.com]

c’mon chaps - pour some more crud from the filthy fossil fuel industry into the river
Coal? why not.
Oil? fine.
Gas? why not,
but please, no clean, safe, nuclear
power.
Good job it’s not a gallon of
low-level nuclear waste.
Roll up, roll up - poor your arsenic
and mercury into our river.
A million gallons of crud a day should be great
Good thing the filthy fossil fuel industry gives Obama
‘donations’.
“25 nov 2009
Last month the Tennessee Department of Environment and
Conservation (TDEC) granted TVA a permit under the Clean
Water Act that will allow the federal corporation to
discharge wastewater polluted with toxic arsenic, mercury
and selenium into the river from the plant in Roane
County. The discharge will come from from a pond that
will hold liquid waste collected from a new air pollution
scrubber.
“That permit is being challenged by three environmental
advocacy groups -- Earthjustice, the Environmental Integrity
Project and the Sierra Club.
“ "The Clean Water Act requires TDEC to
eliminate toxic discharges from the Kingston plant,"
says EIP Attorney Lisa Widawsky. "Instead, incredibly,
TDEC is authorizing new discharges of toxic heavy metals
-- to the tune of one million gallons a day -- into
the same river devastated by the Kingston coal ash spill."

Canada is deelighted with one of the
filthiest fossil fuel site on the planet.
“Stronger investment income, oil royalties and
corporate income tax revenues have buoyed the Alberta
government’s economic picture, reducing the province’s
projected deficit to $4.3-billion.
“In its fiscal update in August, the government
forecast the 2009-10 shortfall to rise to $6.9-billion
from its initial budget projection of a $4.7-billion
deficit.” [Quoted from canada.com]

never-ending
disasters in the filthy fossil fuel industry: 66 trapped,
42 dead
26.11.09 update: Final death toll appears
to be 108, with more than 60 injured.
What was that nonsense about ‘clean
coal’?
What was the nonsense about the dangers of nuclear power?
In fact, it’s the safest mass power known.
Oh don’t worry, it’s nothing
to do with us. We’re trying to clean up the planet.
This is just the China to where we are exporting out manufacturing
to save the planet!
The filth will stay in China:
“At least 42 miners are dead and dozens still
trapped underground after a coal mine explosion in northern
China early Saturday.
“Rescuers have been trying to reach 66 people
who are believed to be half a kilometre inside the state-owned
Xinxing mine, near Hegang City in China's Heilongjiang
province.
“State-run media reports that at the time of
the explosion an evacuation was underway after a warning
about gas levels in the shaft.
“The blast was so powerful that it caused a nearby
building to collapse and could be heard by people in
Hegang, 10 kilometres away.”

just another large filthy fossil fuel industry
disaster
Have you heard about it?
Why don’t the leftist fossil media report these endless
fossil fuel disasters?
Yet they try to generate hysteria if a bucket is dropped at
the very safe nuclear plants.
Who is controlling the fossil
media agenda?
“Monitoring the clean-up of a huge oil spill
in pristine Australian waters could take as long as
seven years, an official said Wednesday as environmentalists
urged a wide-ranging inquiry into the disaster.
“As many as 28,000 barrels of oil have gushed
into the Timor Sea off Western Australia's northern
coast in the 10 weeks since the West Atlas oil rig began
leaking, raising concerns of an environmental disaster.
“Attempts to plug the hole were delayed by the
need to bring equipment from Singapore, the difficulty
of the operation some 2.6 kilometres (1.6 miles) below
the seabed and a fierce inferno fuelled by the leak
which erupted Sunday.” [Quoted from google.com/hostednews]
“A fire-ravaged oil rig and platform in the Timor
Sea remain highly dangerous despite the operators claiming
it is stable, federal Resources Minister Martin Ferguson
says.
“PTTEP Australasia announced on Tuesday afternoon
that its fifth attempt to plug the leaking oil well
had been successful and it had stopped the main fire
at the Montara wellhead platform.
“The oil began leaking on August 21 in the Montara
field near the West Atlas oil rig, more than 200km northwest
of Western Australia's Kimberley coastline.
“During a bid to plug the oil well with heavy
mud on Sunday a fire broke out at the wellhead platform
and the West Atlas oil rig” [Quoted from theage.com.au]

salt-tolerant
plants being developed using gm
“ "Salinity affects the growth of plants
worldwide, particularly in irrigated land where one
third of the world's food is produced. And it is a problem
that is only going to get worse, as pressure to use
less water increases and quality of water decreases,"...”

“An international team of scientists has developed
salt-tolerant plants using a new type of genetic modification
(GM), bringing salt-tolerant cereal crops a step closer
to reality.”

(GM) plants and non-GM plants grown in saline conditions:

“Professor Tester says his team used the technique
to keep salt - as sodium ions (Na+) - out of the leaves
of a model plant species. The researchers modified genes
specifically around the plant's water conducting pipes
(xylem) so that salt is removed from the transpiration
stream before it gets to the shoot.
“ "This reduces the amount of toxic Na+
building up in the shoot and so increases the plant's
tolerance to salinity," Professor Tester says.
“ "In doing this, we've enhanced a process
used naturally by plants to minimise the movement of
Na+ to the shoot. We've used genetic modification to
amplify the process, helping plants to do what they
already do - but to do it much better."
“The team is now in the process of transferring
this technology to crops such as rice, wheat and barley.”

“Fortuno said a large stadium has been prepared
to accommodate some 30,000 people who live in the area
if necessary.
“ "The smoke is extremely toxic," said
Jose Bartolomei, a state epidemiologist who monitors
asthma. "An asthmatic patient will definitely hyper-react
to this."
“Adding to the danger posed by toxic smoke is
the presence of invisible gases such as carbon monoxide
and sulphur, ...” [Quoted from cbc.ca]
Stop press, late Saturday: eighteen tanks now exploded. State of Emergency declared.

once it was acid rain, now it’s acid oceans
 |
Marine biologist Steve Palumbi
of Stanford University makes small
video documantaries - microdocs, or short attention
span science videos - on ecological topics.
One video is on the affect of acid oceans, caused
by carbon dioxide from the air reacting with the
sea water to form acid. The acid dissolves coral,
shells and even limestone rock. The result is the
habitat of marine animals, such as fish, is also
disappearing.
The ocean surface pH (measurement of acidity) was
pH 8.0. It is forecast to be pH 7.8 in fifty year’s
time, a substantial increase in acidity for the
marine life to contend with. |

“... he outlines (with superb clarity) the issue
of ocean acidification and illustrates why it is such
a serious threat to marine ecosystems like coral reefs.
While Steve is using stronger acid than ultimately will
be seen in the world’s oceans as they acidify
(essentially speeding up the process), he illustrates
the key nature of the threat in a way that anyone could
understand.” [Quoted from climateshifts.org]
