Who needs windows anyway? Study shows homes near wind turbines need airtight shut windows

Welcome to your prison comrade

A new Taiwanese study investigated wind farm noise on people in homes made of sandstone, concrete, iron or bricks. And they measured the low frequency noise inside and out, and with windows open and closed. Given the health risks involved, they advised that governments ought to set limits on how close towers can be, and recommend airtight windows that nobody opens much.

Perhaps someone should have done more studies like this before the world installed 750GW of wind power?

The same people that panic about the effect of a hot weekend on your grandchildren a hundred years from now, don’t seem so worried about whether the wind towers destroy your sleep or put you at risk of heart attacks today.

Thanks to MasterResource.

From the introduction of a new paper in Taiwan on the effects of wind turbine noise on people:

LFN [Low Frequency Noise] exposure has been found to cause a variety of health conditions. Exposure to LFN from wind turbines results in headaches, difficulty concentrating, irritability, fatigue, dizziness, tinnitus, aural pain sleep disturbances, and annoyance. Clinically, exposure to LFN from wind turbines may cause increased risk of epilepsy, […]

Coronavirus — borders closing all around the world — no thanks to the WHO

US and Australia close borders and everyone outside China starts tracking contacts…

The official deaths tally has risen to 259, but for the first time the “total recovered” at 287 now exceeds the total deaths. Evidently it’s quicker to die than to recover.

Australia remains the “leader” of the Western nations with 12 confirmed cases. Thankfully, it and the US have finally got serious and both announced today that they would stop people from China from flying straight in. Citizens can return with a two week isolation or quarantine period, but foreigners cannot. This is very good news (as far as virus control goes). Now all the same nations will be furiously, laboriously tracking and tracing the hundreds of potential contacts. In a few weeks we’ll know how contagious it is, and how deadly. And maybe, with much money and dedication we’ll even stop it.

Though in a few weeks a host of secondary countries may develop their own epidemics and virus-free countries will need to block them too.

What’s really remarkable here is how useless, to the point of negligence, the World Health Organisation is.

Finally “world first” study on nine houses shows wind towers make pulsing noise for 3.5 km

Finally, a study looks at data on nine houses within ten kilometers of an old (probably small) wind turbine. What’s amazing about this research is not the result but that this study is so tiny, yet it’s still a “world first”.

There are already probably around 400,000 wind turbines installed around the world.* So you might think that there would have been scores of studies involving hundreds of people and followed up for a year or two. They would have looked at the effect of wind turbines upwind, downwind, side wind, in low wind, high wind, and at different times of day. They’d check for altered sleep patterns, lack of deep sleep, REM sleep, cognitive performance, blood pressure, cortisol levels, and school marks. Dream on. It’s like everything with climate change — who needs data?

Renewables are a $300 billion annual global industry. This work was done with a $1.4 million National Health and Medical Research Council grant. Where is the precautionary principle when we need it?

Air conditioning reduces indoor air pollution — give me cheap electrons

Just another way cheaper electricity saves lives.

It turns out hotter rooms have higher indoor pollution. Levels of formaldehyde are lower in the morning and rise with the temperature. Air conditioning in hot summers, keeps the temperature down and will reduce the amount of formaldehyde and other pollutants from out-gassing from furniture and gypsum walls. Obviously those who can’t afford to run the air conditioner and who live in warmer rooms in summer will be exposed to more pollution.

Though the worst situation was in 1970s homes with radiant heaters installed on gypsum sheets. In that case, people who can’t afford to heat may avoid some fumes.

Opening windows will clear out the indoor pollution, but houses are increasingly being designed to stop draughts to be more energy efficient.

The message: get rich or open windows when it’s nice outside, move those bar heaters off the walls, and buy peace lilies, bamboo palms, and dracaenas.

Researchers uncover indoor pollution hazards

We need to protect our health system from Climate-change-doctors

Doctors are at it again trying to scare people about “climate change”. But all around the world, in every study in every city humans die more from the cold than they do from the heat (and by six to 20 times more). That’s thousands of lives and it happens every single year. Don’t these doctors know anything?

Attributable fraction of deaths: Heat, cold and temperature variability together resulted in 42,414 deaths during the study period, accounting for about 6.0% of all deaths. Most of attributable deaths were due to cold (61.4%), and noticeably, contribution from temperature variability [TV] (28.0%) was greater than that from heat (10.6%). Cheng et al.

The awful truth that incompetent self-serving doctors forgot to mention was that cooler room temperatures allow viruses to survive longer, which is just one of many reasons the Flu Season is always worse in winter.

Break my heart, if “climate change” is real the only thing the docs have to worry about is whether they’ll earn less money in winter.

Here’s the headline:

Health system needs to be protected from climate change: doctors

Scientist create, then cure, baldness, wrinkles and some aging in mice

Here’s a tantalizing bit of gene research. Scientists were able to switch off a central gene in the nucleus of a mouse cell. That in turn meant the mouse’s mitochondria started failing (I’m going to be talking a lot more about these fascinating bits of machinery in our cells). After two months, the poor lab mice were wrinkled, going bald and their organs were aging rapidly, but lo, after the gene in the nucleus was switched on again, the mitochondria were restored, and wow, all the hair and skin grew back to what it had been before.

Mitochondria have their own DNA loops.

Why get excited about mitochondria? These are tiny biological batteries we have inside every cell. The are the mini-factories burning sugar or fat, generating free radicals on a mass scale and churning out the chemical energy that is then used in most of the chemical reactions in our body. They are turning up in every second paper these days related to aging. These little organelles are so important and rule breaking they even have their own DNA loops with 37 genes — this is the only genetic material in us that is not part of the […]

Deadly winter kills 20,000 more British than usual — if only CO2 caused more warming

The world has record high CO2 levels, which supposedly warms us in winter but apparently not as well as cheap electricity does. As the long winter is set to drag on, Brits are being advised to heat one room as well as they can and live there. This is “progress”…

48,000 Brits dead after worst winter in 42 years

After a brief mild spell, temperatures are set to dip again in April after the chilliest March in 21 years.

It is estimated that 20,275 Brits more than average died between December 1 and March

That includes nearly 5,000 Brits under the age of 65 whose lives may have been cut short.

According to the Office of National Statistics, one in 10 cold weather deaths are among under-65s, one in 10 among 65-75s and eight in 10 among over-75s.

The Department of Health also said cold conditions worsen winter killers including flu, chest diseases, heart attacks, strokes and dementia.

It doesn’t matter where you live — more people die in winter than summer all over the world. It’s not outdoor temperatures that matter — it’s the indoor climate that kills.

Last winter 9,000 more British pensioners died than usual — how many were due to high heating costs?

Higher electricity costs mean more people turn off their heaters

There’s a big freeze coming to Britain with minus 12C temperatures possible in the next three weeks.

Last year in winter in England there was a remarkable 40% rise in winter deaths

David Archibald emails that last year was a mild winter for Brits, but the death toll rose from the normal 25,000 excess to 34,000 people. Remembering that it’s moderate cold that kills far more people than extreme temperatures. The UK government advises rooms be heated to at least 18C. (I’ve been in a Canberra house where the temperature fell to 11C indoors, and that was in May.) Despite all the newspaper headlines about outside temperatures, the big killer is indoors.

The big killer is indoor temperature and moderately cold, not extremes.

Campaigners demand urgent cuts to power bill after number of winter deaths among the elderly rise by 40%

Pensioner groups are demanding urgent measures to cut the cost of heat and light after official figures revealed a surge in deaths last winter. There were some 34,300 so-called ‘excess’ deaths during the cold months, according to new figures from the Office of National Statistics (ONS). […]

Forget extreme temperatures: Nothing kills as many people as moderate cold

Some are scoffing at the idea that rising heating costs will kill people. But check out the number-one temperature-killer in 74 million deaths across 13 countries. It’s not the extremes that we need to worry about, the deadly phrase is “mildly suboptimal temperatures”. Look at the blue finger of death in the graph below, starkly showing how irrelevant “extreme heat”, or any other ambient temperature zone, is.

Do you need an excuse to turn the heater on in winter? Low ambient room temperatures will thicken your blood.

Moderate cold accounted for as many as 6.6% of all deaths. Extreme temperatures (either cold or hot) were responsible for only 0·86%.

Join the dots — will we save more lives by:

a) making homes cold now in the hope that lower “carbon” emissions will,

b) mean less deaths from heat in 90 years time despite people probably having better access to heaters and air conditioners?

Would you sacrifice ten years of your life…

Obama spends $8m to research climate change *indoors*

How will that 1mm sea level rise affect your office?

MRCTV

Apparently, no one can escape the dangers of climate change. Even when you are indoors, safe from the “extreme weather events” and flooding that we are told are the result of increases in the Earth’s temperature.

The Obama Administration has awarded $8 Million in government grants to nine universities to study the impact that climate change has on indoor air quality. The EPA defends the move by claiming that climate change’s effects on indoor air pollutants that lead to asthma, as well as mold and mildew, aren’t well understood. However, as with everything negative that occurs in the world, the Obama Administration is assuming that global warming probably has something to do with it.

Not only is the climate impact on asthma not well understood, asthma isn’t understood either. So lets ask a climate model that doesn’t work to figure out future rates of a condition we don’t know the exact cause of during imaginary weather that probably won’t happen.

Really the main effect of anthropogenic climate change is not on our lungs, it’s on our wallets.

I predict man-made-climate-change means the weather will stay […]
