Here we go again: Cranking up
the volume: Sounds travel farther underwater as world's oceans become more acidic - It is common knowledge that
the world's oceans and atmosphere are warming as humans release more and more carbon dioxide into the Earth's
atmosphere. However, fewer people realize that the chemistry of the oceans is also changing—seawater is becoming
more acidic as carbon dioxide from the atmosphere dissolves in the oceans. According to a paper to be published this
week by marine chemists at the Monterey Bay Aquarium Research Institute, these changes in ocean temperature and
chemistry will have an unexpected side effect—sounds will travel farther underwater.
Conservative projections by the Intergovernmental Panel on Climate Change (IPCC) suggest that the chemistry of
seawater could change by 0.3 pH units by 2050 (see below for background information on pH and ocean acidification).
In the October 1, 2008 issue of Geophysical Research Letters, Keith Hester and his coauthors calculate that this
change in ocean acidity would allow sounds to travel up to 70 percent farther underwater. This will increase the
amount of background noise in the oceans and could affect the behavior of marine mammals. (Monterey Bay Aquarium
Research Institute)
The David and Lucile Packard Foundation funds research that 'finds a problem' -- there's a surprise... So, what
have we got this time? Atmospheric CO2 increase making oceans slightly less alkaline (thus, more
acidic) -- check. Significance of this to marine critters? Well, nothing much really since they've nearly all
evolved while atmospheric carbon dioxide levels were much higher and only about 10% of the last 250 million years
have seen levels anywhere near as low as they are now. Cetaceans, with their evolutionary roots 30-50 million
years ago, may find their sonar and communication range increasing back toward that achieved by their ancestors.
Weasel factor ("suggest" "could"... ): moderate to high. Distraction from morning coffee: nil.
Sidebar: check out the axiomatic: "It is common knowledge that the world's oceans and atmosphere are
warming as humans release more and more carbon dioxide into the Earth's atmosphere." Is that true? Well,
kind of. What measures we have suggest the world, including its oceans, has warmed somewhat since the Little Ice
Age (nothing too contentious there) so that part is true. Similarly it is true that humans are using more fossil
fuels and releasing more carbon dioxide from combustion, cement manufacture and use and so on. However, whether
the latter is responsible for the former is highly contentious and doubtful. That it is common knowledge is
equally doubtful given the increasingly expressed skepticism over gorebull warming. This is probably why there is
such an effort to indoctrinate the young and if that effort succeeds then gorebull warming will be common
knowledge. Chilling, isn't it?
The Nonsense of Global Warming - Marxism,
Freudianism, global warming. These are proof--of which history offers so many examples--that people can be suckers
on a grand scale. To their fanatical followers they are a substitute for religion. Global warming, in particular, is
a creed, a faith, a dogma that has little to do with science. If people are in need of religion, why don't they just
turn to the genuine article? (Paul Johnson, Forbes Magazine)
Carbon surveillance: Mobile
phones to track carbon footprint - Keeping track of your carbon footprint could become as simple as slipping a
mobile phone in your pocket: a London-based start-up company has developed software for mobile phones that uses
global positioning satellites to work out automatically whether you are walking, driving or flying and then
calculate your impact on the environment. (The Guardian)
How long before politicians want to begin taxing you for your emissions based on this kind of constant
surveillance? Already politicians want to track cars to tax road usage, issue carbon ration cards to control your
purchasing power and so on, how long before they want to make this kind of nonsense compulsory?
Latest from the hair shirt killjoys: Meat
must be rationed to four portions a week, says report on climate change - People will have to be rationed to
four modest portions of meat and one litre of milk a week if the world is to avoid run-away climate change, a major
new report warns.
The report, by the Food Climate Research Network, based at the University of Surrey, also says total food
consumption should be reduced, especially "low nutritional value" treats such as alcohol, sweets and
chocolates. (The Guardian)
Look, guys, 'runaway' climate change is not possible on our water-rich little world. Two effects circumvent the
model fudge of water vapor feedback greatly magnifying enhanced greenhouse from increasing atmospheric carbon
dioxide: one is precipitation -- keep adding to humidity and you get cloud formation and precipitation, it's a
locally self-limiting system, in other words and; two: the way to get more water vapor into the system is to
enlarge the moist atmosphere zone, increasing cloud area and its associated albedo, thus returning more sunlight
to space -- a global thermostat shutting off the heat. The first effect results in accelerated latent heat
transfer (cooling the planet's surface) while the second reduces solar energy input (cooling the planet's
surface).
Why? Carbon dioxide 'scrubber' captures greenhouse
gases - University of Calgary climate change scientist David Keith and his team are working to efficiently
capture the greenhouse gas carbon dioxide directly from the air, using near-commercial technology. (University of
Calgary)
Atmospheric carbon dioxide supports life on Earth, what have these twits got against life?
Renewables Get Lost in Shuffle of Inter-Cameral Turf War;
Taxpayer Wins - That’s great news for the taxpayer because renewable energy subsidies are a huge waste of
money. When the government meddles in any emergent industry like renewables with tax favors, it is picking and
choosing winners. But bureaucrats and politicians cannot be expected to invest well; instead they are prone to
awarding constituents or pleasing superiors. This is the dynamic that produced synfuels, ethanol, futuregen, and a
host of other government backed energy boondoggles. (William Yeatman, Cooler Heads Digest)
The Pickens Plan: Questions Unanswered - Introduction: On
July 7, 2008, Texas billionaire T. Boone Pickens introduced the “Pickens Plan,” an ambitious proposal to reduce
America’s dependence on foreign oil by one-third over the next ten years.1
The cornerstone of the Pickens Plan is replacing the natural gas now used to generate electricity with wind power,
and then using the saved natural gas to power vehicles that presently run on gasoline.2
It’s a bold plan from a bold man.
Pickens should be credited for understanding that America has an urgent need to secure its energy independence. His
website says: “As imports grow and world prices rise, the amount of money we send to foreign nations every year is
soaring. At current oil prices, we will send $700 billion out of the country this year alone – that’s four times
the annual cost of the Iraq war.”3
While Capitol Hill offers partisan bickering, Pickens appears to be offering a solution. And, as Pickens is prepared
to spend $58 million to promote his plan,4 his advocacy could have an enormous impact on America’s energy policy
for decades to come.
But while Pickens appears confident, his claims raise questions. Has oil production finally and irrevocably peaked,
as Pickens claims? Why use wind power instead of nuclear power? Are natural gas-powered vehicles a viable
alternative to gasoline-powered cars, and would switching to them improve America’s security? What does Pickens
believe the federal government should do to make his plan a reality? Might he or the firms he owns benefit
financially from such federal aid? (Reece A. Epstein and David A. Ridenour, National Policy Center)
Next prohibition: salt - Here is a
question I added to my chapter on logic today.
New York City “Health Czar” Thomas Frieden (D), who successfully banned smoking and trans fat in
restaurants and who now wants to add salt to the list, said in an issue of Circulation: Cardiovascular Quality and
Outcomes that “cardiovascular disease is the leading cause of death in the United States.” Describe why no
government or no person, no matter the purity of their hearts, can ever eliminate the leading cause of death.
I’ll answer that in a moment. First, Frieden is engaged in yet another attempt by the government to increase
control over your life. Their reasoning goes “You are not smart enough to avoid foods which we claim—without
error—are bad for you. Therefore, we shall regulate or ban such foods and save you from making decisions for
yourself. There are some choices you should not be allowed to make.” (William M. Briggs, Statistician)
