Would YOU accept less anesthetic during surgery to save the planet? Doctors say it could reduce world's carbon footprint... by up to 0.1%

First they wanted us to eat bugs -- and now this. Warmists are a danger to civilization

Researchers are asking doctors to use less anesthesia on their surgery patients in the name of climate change.

Doctors from the Henry Ford Health in Detroit, Michigan, said it could significantly reduce the carbon footprint of hospitals in the US.

Research suggests that inhaled anesthesia accounts for up to 0.1 percent of the world's carbon emissions.

Dr Mohamed Fayed, a senior anesthetist at the Henry Ford, said: 'Global warming is affecting our daily life more and more, and the reduction of greenhouse gas emissions has become crucial.

'No matter how small each effect is, it will add up. As anesthesiologists, we can contribute significantly to this cause by making little changes in our daily practice — such as lowering the flow of anesthetic gas — without affecting patient care.'

He made the comments at the American Society of Anesthesiologists annual event last Friday in Orlando, Florida.

Henry Ford fesearchers gathered data from 13,000 patients over the seven months from March to September 2021. They set a goal of reducing anesthesia use to under 3liters of anesthesia every minute (L/m) per surgery when possible.

Trying to reduce the overall use of anesthesia in the hospital, the team instructed physicians to dial back the amount used in between those portions of the procedure.

This is only for inhaled anesthetics, not sedation or localized anesthetics used in smaller procedures.

At the start of their research, only 65 percent of surgeries fell under that threshold. After months of instruction, they had reduced the figure to just seven percent.

Now, they want to reduce anesthesia use to below 2L/m in as many operations as possible.

'For a long time, there was a notion that the greenhouse effect caused in health care settings was an inevitable and unavoidable cost of providing patient care,' said Dr. Fayed.

'But we have learned that reducing anesthetic gas flow is one of the many ways health care can lessen its contribution to the global warming crisis, along with reducing waste, turning off lights and equipment when not in use and challenging practice habits, as long as they don't compromise patient care.'

The amount of anesthesia a person receives during surgery depends on their weight and other factors such as time in surgery, age and potential risk factors

Surgical anesthetics are made up of multiple chemicals, including nitrous oxide halothane, isoflurance, desflurance, sevoflurane.

An hour of using anesthesia can cause the equivalent impact on the atmosphere as someone driving a car for nearly 500 miles, researchers say.

The Henry Ford research team, which presented their findings at ADVANCE 2023, in Orlando, Florida, this week, explains that surgical anesthesia requires fresh gas at the start and end of procedures.

Use of high levels of anesthesia does come with risks. While it is safe in nearly all cases, too much anesthesia can deprive cells of oxygen and cause stroke, brain injury, coma or even death.

There are risks from not receiving enough anesthesia too, though. A person could always wake up during surgery, which can be painful and highly traumatic.


Climate and Human History

We are being told that continued warming will lead to catastrophic events. Human history tells quite a different story. In the previous much warmer periods, humanity flourished.

The rise of the first great civilizations occurred during a period known as the Bronze Age. Great empires arose and life flourished around the Mediterranean (Mycenaean), in Egypt (Old Kingdom), China (Xia dynasty), Mesopotamia (Hittite, Syrian & Babylonian) and in the Indus Valley of India (Harrapan). In this period, humanity saw early advancements such as the inventions of the wheel, writing, bronze smelting and wine making.

Minoan era temperatures are mainly known from ice cores and other proxies. We know that the crop millet was grown in southern Scandinavia and the Tibetan Plateau -- areas far from the tropical and subtropical regions that are home to the grain now. Comparing today’s average annual temperature in Denmark to that required to grow millet indicates that the temperature was at least 2 degrees Celsius (3.6°F) warmer during the Minoan period than today.

Despite temperatures much higher than the most-likely rise predicted for the 21st century by the IPCC, there was no tipping point or cascade of climate catastrophes. Rather, Earth and humanity thrived.



Are You Really Against Fossil Fuels? Read this Before You Answer

By Vijay Jayaraj

It is easy for anyone to say that they are against fossil fuels. Opposition to coal, oil and natural gas is fashionable and will prompt heads to nod and even hands to applaud in most places.

But are people aware of the extent to which their lives are dependent on fossil fuels? Do they know that more than 90 percent of things used in their everyday lives are derived from fossil fuels?

From your toothbrush to your car tire, a majority of the things you use today has been made possible because of fossil fuels. Shoes, refrigerators, washing machines, coffee makers, furniture, pens, eating utensils, eyeglasses, commodes, medical gear, camping equipment, and the list goes on and on.

Consider the computer or the phone from which you are reading this article. They are made of glass, metal, plastic, lithium and silicon – all of which require fossil fuels to mine, process or manufacture. While some are chemical derivatives of fossil fuels, all depend one way or another on their combustion for electricity generation, process heat or transportation.

You wouldn’t have the iPhone, Android or MacBook without fossil fuels. Imagine the irony of typing out “end oil” from a phone that is made from fossil fuels! Or supporting climate activism by relaying video that was recorded with a camera made from fossil fuels! Of course, this sort of irony is displayed regularly and missed constantly.

In short, the most fundamental necessities – and the most cherished conveniences – of daily life are products dependent on the use of fossil fuels.

Electricity and Transportation

The industrial era was a time of great change, and the use of fossil fuels played a big part in that. From the early 1800s to the mid-1900s, coal was the primary fuel source for industry and transportation. Oil and natural gas became much more prominent in the latter half of the 20th century.

Cars, trucks, planes, ships, and trains use oil. If you go electric, the electricity for the vehicle is again predominantly generated from coal or gas. Even wind, solar, nuclear and hydro power are dependent on manufacturing and mining processes reliant on fossil fuels. If you intend to start a new life on the planet Mars or the moon, the rockets you use need fossil fuels.

While the use of fossil fuels as a source for electricity generation and transportation fuel has been discussed widely, their role in the manufacturing and farming sectors is seldom highlighted.

Cement, Steel, and Plastic

Cement, steel, and plastic are essential materials that are used in the construction, transportation and manufacturing industries, playing a key role in the development of modern civilization.

Being the primary ingredient of concrete, cement is the most frequently used construction material in the 21st century. It is used in the construction of homes, roads, bridges, commercial buildings and other infrastructure. The manufacture of cement is one of the most energy intensive processes, requiring the mining of limestone and other minerals that are eventually heated in kilns at temperatures of 2,700 degrees Fahrenheit.

Another common construction material is steel, which is preferred for its immense strength compared to its volume and weight – a quality desirable for the structural frameworks of tall buildings, industrial facilities and bridges. Steel is also used in the reinforced concrete of roads and in the manufacture of vehicles, machinery, tools and appliances.

Paints, resins, fiberglass, coatings, varnishes, adhesives, and thousands of other materials are all made from fossil fuels. It is likely the clothing that you are wearing now was made using fossil fuels. In fact, most carpets, fabrics, coatings, cushions, upholstery, drapes, spandex and other textiles are made with the help of fossil fuels.

Fossil fuels are used as raw materials in the production of many chemicals and plastics. Lightweight, durable and versatile, plastics are used in a wide range of products, from packaging and consumer goods to automotive parts and medical devices.

Food Production

Fertilizers – produced with the help of fossil fuels – replenish the soil with essential nutrients like nitrogen, phosphorus, and potassium, improving soil structure and fertility. Fertilizers have played a crucial role in meeting the global food demand by increasing crop yields by as much as 50 percent.

According to OurWorldInData, which compiles information from the United Nations and World Bank, “From 1961 to 2014, global cereal production has increased by 280 percent. If we compare this increase to that of total population (which increased by only 136 percent over the same period), we see that global cereal production has grown at a much faster rate than the population.”

Not only do fossil fuels enable us to meet the bare necessities our everyday lives, but they are also the reason for the worldwide improvement in the quality of life since the 1950s.

The campaign against fossil fuels focuses on their use in the generation of electricity. However, every part of our material life is made better by fossil fuel derivates. They help us live more efficiently, safely and in an environmentally friendly way, reducing poverty and helping billions enjoy decent and safe lives.


Here’s Why The World Is Producing More Food

by Vijay Jayaraj

Countries all over the world are surpassing previous records for production of food crops. This is good news that stands in stark contrast to the apocalyptic picture that the media paints daily in reports on climate and weather.

Because food is fundamental to human survival, even a slight increase in its price can significantly affect millions – even billions – of people. “When food fails, everything fails,” said Geraldine Matchett, Co-Chair of the CEO Alliance on Food, Nature and Health.

So, it is not surprising that the purveyors of fear present climate change as the biggest threat to the world’s food security. Endlessly recycled articles and TV programs constantly peddle the misinformation that a supposedly dangerously warming Earth poses a risk to crops or is already destroying them.

However, in the real world, data show historically high crop production all over the globe. This is because climate change has aided in the proliferation of food crops, as well as other vegetation. Abundant harvests continue to affirm this. As in previous years, 2023 is expected to produce records for agricultural production in many countries.

Wheat is a major source of calories, protein and essential nutrients, and it is relatively easy to grow and store. A reliable source of food in many regions, wheat is the staple crop for an estimated 35% of the world population.

After a year of supply uncertainty due to the war in Ukraine, wheat production is slated for a global increase.

In the UK, for example, wheat production in 2022-23 is expected to increase by 450,000 tons from the previous year. In the U.S., winter wheat has been planted across nearly 37 million acres, up by 11% from the prior year and the highest in eight years.

In Africa, Zimbabwe produced a record 375,000 tons of wheat in 2022, making the country self-sufficient. The new record is 13% higher than the previous year and surpasses 50-year-old records. This saves the country 300 million dollars that otherwise would have been spent on wheat imports.

India is second only to China in wheat production. The Indian government reports that wheat production will reach an all-time high of 112 million tons in the 2022-23 crop year.

“The prospect of the wheat crop is better due to current weather conditions and slightly higher acreage,” The Economic Times reported.

In fact, globally, there has been a steady increase in yields of wheat as measured in tons per hectare, with some of the highest being in China.

Crop yields in the 21st century have been increasing due to a combination of factors. Among them are the use of modern technologies, the development of high-yielding crop varieties through plant breeding and genetic engineering and the application of fertilizers.

Nonetheless, the level of production would not have been possible without the post-Little Ice Age warming of the earth since the 18th century and the modern increase of atmospheric CO2.

Greater warmth has allowed for longer growing seasons and the cultivation of a wider variety of crops. Higher CO2 concentrations have helped plants to photosynthesize more efficiently, resulting in increased growth and crop yields.

Even in the worst-case scenarios of alarmists, where temperatures rise sharply, global agriculture can adapt through genetically advanced food crop varieties that are resilient to extreme droughts and high temperatures.

There is simply no reason for alarm over climate’s impact on global food production either today, next year or in 100 years. In fact, climate is aiding crop growth and helping the world to feed growing populations.
