Ellis Air Conditioning & Heating tells us,
With the heat indexes reaching into the hundreds from May to September, central air Dallas provides comfort to its residents, as well as safety to their elder residents, and small children who have less of a tolerance for high heat levels. . . .Ellis is not engaged in advertising hype. It is simply stating what everyone who has ever spent a summer in Dallas already knows. The Dallas heat can be unendurable for the healthy, and downright deadly for the old and unhealthy. Dallas is not the only place where summer heat kills people. That is happening in Japan right now.
Providing comfort via central air is a luxury most Dallas natives take for granted. That is, until the central air is not working. Living without central air in near 100 degree weather can be unbearable for some, and unsafe for others. It is important, as the hotter months approach in Dallas, to protect oneself from a situation where their central air unit may become disabled.
From June 1 to July 10, the latest period available, 26 people died from heatstroke, compared with six in the same period last year, according to the Fire and Disaster Management Agency. The number of people taken by ambulance to hospitals for heatstroke more than tripled to 12,973, with 48 percent in the most-at-risk group aged 65 years or older.Now if those 26 people had died from causes that were related to radiation from nuclear accidents, headlines would have told the story all over the world. But those deaths were due to radiation from the sun, and to an absence of electricity due to the shutdown of nuclear power plants.
Of course global warming is also playing a role in the Japanese deaths,
Temperatures in eastern Japan, including Tokyo, were 3.8 degrees higher than the 30-year average in the last 10 days of June or the highest since at least 1961, . . .Even last years Japanese heatstroke related death total pales to almost insignificance when compared to the 70,000 plus heat related deaths in Western Europe during the summer of 2003. Global warming skeptics call global warming realists, alarmists. Climate researchers suggests that within a few decades there will regularly be more summer heat related deaths in Europe, than cold related deaths. How many heat related deaths is it going to take before the skeptics acknowledge what is going on?
Japan has shut 35 of its 54 atomic reactors for safety checks after the March 11 earthquake triggered the worst nuclear crisis since Chernobyl, reducing total power capacity by 11 percent. Conservation efforts amid hotter temperatures are raising concern of a repeat of last year, when a record 1,718 people died of heatstroke as the summer heat broke records.
Well I am not going to further bash the climate skeptics after the thrashing I gave them on Friday. Today my targets are the anti-nukes.
In Texas it is realized that air conditioning is a matter of public health. Heat waves bring with them deaths as I have already noted. In particular the deaths of older people, the sick and of babies.. The way to control that is to being some means of staying cool into their lives. That means fans and often air conditioning. That, of course, also means electricity, since fans and AC require electricity to operate.
I must confess that I expected Greenpeace to stoically do without air conditioning, but this turns out to not be the case. The Greenpeace ship, the Rainbow Warrior III, includes a diesel engine, an electricity generator, and air conditioning. Greenpeace is recommending hydrocarbon technology that increases air conditioning efficiency by 10% to 20%. Tht is hardly the sort of efficiency gain that Amory Lovins gets excited about. We are clearly going to see more demand for air conditioning, as matters of public health, not just in the United States, but in Western Europe, China, and indeed all over the world.
In Oklahoma the When a water main that supported state government office buildings bke,
13 state government buildings at the capitol were closed after a break in a water main that shut off air-conditioning systems.Computers generate heat, human bodies generate heat.
Computer systems in Oklahoma's state agencies were turned off and 1,000 employees sent home, said spokeswoman Sara Cowden of the Department of Central Services.
This summer will not break most of the heat wave records established in 1980, but there is a hint this summer that it will not be many more summers before the 1980 records start to fall. Greenpeace knows this, yet in its energy plan, , Energy [R]evolution: A Sustainable U.S.A. Energy Outlook.Greenpeace anticipates far more electrical reduction through efficiency than the 10% to 20% improvement in air conditioning efficiency that the hydrocarbon technology it advocates would lead too. None of the electricity will be generated by low carbon nuclear power plants. Instead Greenpeace plans to rely on carbon emitting natural gas power plants to bridge the gap.
Climate scientist expect more extreme heat waves, and for them to get worse. Texas like heat waves are emerging in places that have never recorded such heat before. A year ago the city of Moscow, Russia, is reported to have reached an all time record of 102 degrees during an extreme heat wave. The extreme heat was accompanied by massive crop loss - 40% of Russia's grain harvest - and hugh wild fires - 1.600,000 acres burned.
Climate scientist Roger A. Pielke Jr. says
The IPCC [Intergovernmental Panel on Climate Change] defines “climate change” as a change in the statistics of weather occurring over 30 years or longer and persisting for decades. Thus, the detection of a change in climate requires long-term records.Pielke says,
It is true that overall damage from tornadoes, floods, and hurricanes has been increasing in recent decades. A recent literature review of extreme event impacts around the world found that everywhere that researchers have looked, this increase can be entirely explained by increasing value of property at risk and increasing exposures to these hazards.The Insurance Industry disagrees with Pielke. Peter Höppe, head of Munich Re's Geo Risks Research/Corporate Climate Center states,
Our figures indicate a trend towards an increase in extreme weather events that can only be fully explained by climate change.If Roger Puekle proves too conservative about climate change, he will still have tenure ands won't loose his job. Munich Re could go out of business if their climate change projections are wrong.
Like insurance companies, we cannot afford to take the risk that climate skeptics are wrong. The Torch of 2011 should offer us enough light to see that we should be trying to avoid climate change rather than waiting to see if it happens. As Oliver Cromwell once wrote to the Parlement of Scotland, I would say to the climate change skeptics,
Think it possible that you might be mistaken,and if you are mistaken, what the cost of that mistake will be. You are gambling with peoples' lives. I would say the same thing to Greenpeace, but does Greenpeace really care about human life?

On the use of hydrocarbons for refrigerants I find myself on the same side as Greenpeace. It probably won't happen here in the USA. I can see the lawyers already preparing their cases for the time when the first refrigerator explodes. Never mind the fact the the risk is very small since refrigerant leaks are almost always too slow to form combustable mixtures with air. And the amount of hydrocarbons is on the same order as in a large butane lighter. The the simple expediant of taking the thermostat and door light switch and either sealing them or moving them outside the refrigerated space would greatly reduce the remaining small hazard.
Having said all that, we are not going to conserve our way to low CO2 emissions or prosperity.
Donb, I am of course in favor of efficiency, since efficiency is the path to wealth, and I think that making everyone rich is a worth while goal of future energy plans. But you make a lot of people righ by making available energy go further, not by deminishing energy resources.
donb,
a very good and efficient candidate as fluid for heat pumps is indeed CO2, Japanese Sanyo already commercialized in the European and Asian markets such an air to water heat pump, capable to work even at extreme conditions (-10 or -20 °C) with a still slightly positive COP.

And we know CO2 is perfectly safe and clean even from the GWP pov - not that I' m a great fan of it, I rather prefer for hotter climates like Texas a mix of air to air heat pumps (not air to water one) and solar thermal only for hot water, but it's anyway a possible development
Thermodynamics means that prefect efficiency is unobtainable. And the Law of Diminishing Returns means there will always be a point beyond which better efficiency is not worth it.
Efficiency is a valuable goal, but it should not be put up on an altar and worshiped.
The pursuit of green energy is increasing fuel poverty in Europe, notably in Britain, so increasing deaths from temperature extremes is all too foreseeable.
@LarryD-
I could not agree more that ultimate efficiency is not the goal, but the most economical combination of efficiency and energy sources.
Hyrdocarbons for refrigerants have the advantage of being cheap and efficient. During the phase-out of R-12, there was much discussion of using a mixture of butane and propane as a substitute. With no change in the mechanicals nor lubricating oil, more efficiency is obtained. Cheaper, better and more efficient as well - this is the kind of efficiency improvements I really like to see. Of course, this didn't happen here in the USA due to FUD stirred up by the lawyer class.
I heard of a few automotive HVAC service outfits that replaced the CFC in car air-conditioners with LPG. The transport authorities didn't like that idea much and stated that any car so-altered would not receive registration. They had no way to check though and in the end nothing happened. So there are cars runnning about with LPG as work fluid.
I wouldn't do it myself but so far there have not been any problems.

What's wrong with Pielke? Can't he see that the climate is a complex system and that: Massive loss of Arctic sea ice, 4% increase in atmospheric water vapour, 0.8 degrees C more thermal atmospheric energy, 0.5 degrees C warmer ocean energy, a huge mix of aerosols and 425 ppm CO2e, a 30% increase, land-use change, and airplane and ship contrails. I think we need college kids to get angry and track down the climate deniers that are sabotaging their future. He says he agrees with GW, that there has been an increase, but its due to increased exposure and property value. What a wishful thinking clown (or paid denier). Whatever simple statistical analysis Pielke is using, he is wrong.
there are some places where we can fry an egg on the road...and people live there with any air condition ... human body is capable of adjusting itself in a short period of time in any environment.
That's true. People live everywhere after all, from Inuits up North to Africans living on the equator. Humans have an amazing ability to adapt and make the most of their environment but also make their environment work for them.

The very heart of your writing shilst sounding agreeable at first, did not settle very well with me personally after some time. Someplace within the paragraphs you were able to make me a believer but just for a while. I nevertheless have a problem with your leaps in assumptions and one would do well to fill in those breaks. In the event you actually can accomplish that, I will definitely end up being fascinated.
Its such as you learn my thoughts! You seem to grasp so much approximately this, such as you wrote the ebook in it or something. I think that you simply can do with some% to force the massage house a bit, however other than that this is magnificent blog. An excellent read. I will certainly be back.
