225. Thoughtless Human Nature May Cause Our Extinction.

22 Mar

Here are the critical areas:

Covid-19 and other similar viruses. These may be a never ending problem, because so many people throughout the world are not wearing masks, distancing, isolating, etc. Young people, older people, poorly educated people and others, simply are not following the rules and most go unpunished. It is human nature. Even our past president had huge rallies with unprotected people packed together, promoting numerous new infections. There is a powerful tendency for people to do what was always, previously acceptable.

It is possible that improved vaccines will ultimately keep us safe, but there will always be a large percentage of the population that will not accept them. Because the viruses evolve, it may never be possible to completely stop them. However, there are current efforts to rebuild an excellent CDC and WHO, and new support for science, which will help.

Climate change problems of increased floods, droughts, fires, and hurricanes are serious threats to our survival and are already killing thousands of people. Much of the resulting disaster is mass migrations, which will gradually increase as weather patterns change that affect food production. Our leaders and the people must all strive to replace the use of fossil fuels with green sources of electricity. It is the nature of the rich business owners to ignore these current and future problems because action will involve unwanted extra expense. It is usually profitable to keep doing things in the same way even if they are indirectly destructive.

People will hesitate to buy electric vehicles, lower home energy use, and to use solar panels. It is human nature to keep life simple and not made improvements when there is no incentive.

Massive migrations have already been mentioned, but deserve additional discussion. I see migrations from Syria and other unstable countries as responsible for much of the world’s problems, probably including BREXIT and some past US government policies. Generally it is the human nature of less-educated people to be fearful of immigrants; and the previous US admin promoted these fears.

It is a human nature to elect our leaders based on their speeches and emotions, rather than on the basis of intelligence and relevant experience. People that appear powerful, good looking, and likable are often elected. Traits necessary for election are not necessarily the ones best for governing.

Ignoring science is the nature of many people, because it is often more complicated. Many want all government problems to be simplified and solved by simple solutions, that they can understand. But it is often the “simple” solutions that create new problems.

Destructive human nature includes excesses in the areas of greed, racism, and revenge. These factors can lead to many kinds of destabilization and distraction from the real problems described above.

132. Latest Climate Change Info: Simplified

29 Dec

It is vital that our government supports climate change programs.The dangers are serious and some harmful effects are already happening. Helping people and leaders to understand the science is my contribution. Here are the fundamentals, briefly:

Light from Sun >> Heats earth >> Heat energy Rises /\ /\  from earth
Some rising heat is blocked ]]]] from escaping by gases like CO2
Burning fuel increases CO2 causing more ]]]]]] blockage & warmth

More Detail:
Light from the Sun passes through our atmosphere and warms our planet. The resulting heat rises and some is blocked from escaping into space by “greenhouse” gases: carbon dioxide (CO2), methane, water, and others. Small quantities of these gases are naturally in the atmosphere, and the amount is relatively stable.

But when we burn fuel and create more heat-blocking CO2, there is excessive planet warming. CO2 and other “greenhouse gases” are like a blanket around our planet. See below for more scientific detail.

How do we know that planet warming is caused by human activity?
1, The carbon dioxide emitted by burning coal, natural gas, and oil has a unique chemical pattern — and the additional CO2 in the atmosphere bears that signature. (See below for more detail.)

2. The CO2 and warming are closely correlated with the history of the industrial revolution, which involved the burning of coal and gasolene. As the usage of fossil fuels increased, the warming increased. During the history of the Earth, there were temperature cycles, but these natural cycles are very much slower than the current rapid temperature warming. No other “natural” factors could have caused this increase. See this NASA reference for actual data:  https://climate.nasa.gov/evidence/

What are the dangers of global warming? Warming causes arctic and other northern ice to melt. This is already well established by photographic evidence. The consequence is warmer oceans, rising sea levels, and changes in ocean currents.

The warming of oceans increases the strength of hurricanes. In recent years, hurricanes are worse than before. Changes in ocean currents shift land temperatures and rainfall so that some lands (like California) are drier and other places are flooded. Inhabited land that is close (or even less than) sea level is starting to flood, due to a slight rise in sea level. A good example is flooding in Venice, Italy, where the sea level has consistently risen by a total of 26cm since 1870. Many highly populated coastal areas of the USA are vulnerable. Some ocean islands are no longer habitable.

Scientists have spent thousands of hours recording and studying these factors. All of these facts are published in reputable scientific journals and magazines, such as Scientific American and Science. All reputable scientists support these findings. A recent official government report and NASA report supports all these facts. Politicians sometimes dispute these facts because their donors might need to spend money to correct their operations. Scientists are not political with respect to science.

Added scientific clarifications
Rising heat energy (infrared radiation) is effectively  “blocked” by CO2 and other greenhouse gases. Most of our atmosphere consists of oxygen and nitrogen, which are small molecules and have little effect on rising heat. Greenhouse gases like CO2 have larger molecules and can absorb heat energy. Shortly after absorption, the heat energy is re-emitted in any direction. The part that goes downward tends to warm the earth. Long before humans inhabited the Earth, greenhouse gases were in the atmosphere at an almost fixed level as a result of opposing processes that produced an equilibrium. These gases warmed the Earth enough to make it habitable for humans and other animals. Burning fuels has increased the heat, causing harmful effects.

CO2 from fuel burning can be identified because it contains tiny amounts of certain inert (noble) gases, Other “natural” CO2 has a different pattern of these inert gases. This is often referred to as a “fingerprint.

Scientists have been working diligently on the problem of added global warming. There are basically two types of solution:  1. Reduce the burning of fuels by producing alternative energy like windmills and solar arrays, and 2. Develop industrial processes for removing greenhouse gases from the atmosphere. Number 1 is already in major use. Number 2 is being developed by researchers, but the effectiveness is not yet known . Our gov needs to support BOTH of these efforts, trying to remove CO2 (etc) from the atmosphere will not be enough.
