154. Champions: Climate Change Crisis

20 Mar

This is an update on the latest efforts, findings, and theories on the Climate Change crisis. But first, I want to acknowledge the great contributions of  Ex-Veep Al Gore (who should have been elected president) in defining and promoting the climate change crisis. I also want to mention presidential candidate Governor Jay Inslee who has made climate change his most important issue. Now, there is an increasing number of leaders (mostly Dems.) who are enthusiastically promoting climate endeavors. 98% of all reputable scientists support the idea that human activities are causing global warming.

A new approach to fixing Climate Change is the work of Penny Chisholm The marine microbe Prochlorococcus draws in CO2 and uses sunlight to produce oxygen and sugar. The functioning of this microbe may hold the key to reducing CO2 in the air, saving our planet from climate-change devastation.  Since the world is not doing so well in producing less carbon dioxide, it is very important to support promising research on removing CO2 from the air. Penny Chisholm, in her recent TED talk, is one of the researchers in this area. This method may be key to saving our planet.  Please tell Trump and Congress to support research in this area and fund grants for testing. 

Another promising method to help is using Carbon Cure. It is a method of injecting CO2 into concrete. This removes it from the atmosphere and also helps to strengthen the concrete — so less is needed. Using this method, climate-change is helped in two ways. We need a President that can support climate efforts like this.

There are many other methods of carbon dioxide removal from the atmosphere, by natural and tech processes.  For a really good discussion, I recommend reading:  http://www.eesi.org/articles/view/carbon-removal-strategies-a-broad-overview  .

The “Green New Deal” proposed by Alexandria Ocasio-Cortez and others, is filled with good progressive ideas and emphasizes the Climate Change crisis.  Many of the Democrat Presidential candidates support the deal fully or substantially.

The President has established a Climate Change Scientific Panel to investigate. It is led by 79 y.o. William Happer, C. Fogg B. Physics Professor Emeritus at Princeton, who is notable for being the only professor stating that excess CO2 in the atmosphere is beneficial. Note that “emeritus” means retired. In essence, Happer says: don’t worry about global warming because CO2 will be good for agriculture. Many commentators believe that the president’s panel was set up just to “muddy the waters.”  The USA Military, most other countries, some CEO’s and many members of Trump’s staff are concerned about global warming dangers, which in fact, we are already experiencing.

Recent investigations of show that climate-change is taking place much faster than previously estimated. One reason is that the melting of ice exposes dark-colored earth that tends to absorb more heat. Studies of the Arctic, Antarctic, and glaciers clearly show significant changes due to warming. Please see my BasicCauses blog number 147 for more info.  Here are the references for the two most authoritative recent reports.  One is  United Nations Special Scientific Panel released October 8, 2018. This report indicates the rapid change.  The other report is the “Fourth National Climate Assessment” (Nov. 23, 2018) by US Global Change Research program.

What we must do right now is support research like removing CO2 from the air and developing better batteries for electric needs. A panel of experts chosen by the National Science Foundation (or similar) should determine where the funding goes. Mr. President, time is running out, this is your last chance to do the right thing in this area.

147. Attention to Climate is Urgent

19 Feb

The vast majority of nations in the world understand the urgency of climate solutions. We already have worse hurricanes, new flooding, forest fires, glaciers and polar caps melting, sea levels rising, etc. The city of Venice, Italy is already sinking and flooding due to climate factors. Major USA coastal cities and most of Florida will soon be at risk.

Our President refuses to recognize this vital problem because it does not suit his billionaire friends, like the Charles and David Koch of Koch Industries. Making proper changes would cost them a few billion out of their 100 or so billion in assets. Helping his extremely rich friends (and donors) is more important than saving millions of lives and in other ways protecting the USA and many others in the world.

Two very authoritative reports have definitely concluded that the average global temperature is increasing, and the increase is caused by human activities, such as burning fossil fuels. (The Koch family has been in the oil business for decades.) One report is by a United Nations Special Scientific Panel released October 8, 2018. This report indicated that the climate is changing faster than originally anticipated. The other report is the “Fourth National Climate Assessment” (Nov. 23, 2018) by US Global Change Research program. This report is from Trumps gov and he only very reluctantly released it. The official report summary says: “Climate change creates new risks and exacerbates existing vulnerabilities in communities across the United States, presenting growing challenges to human health and safety, quality of life, and the rate of economic growth.”   Trillions of dollars and millions of lives are at stake. Contrary to his claim of “draining the swamp,” his cabinet is full of climate deniers and promoters of CO2 pollution.

The Trump position on climate-change has vacillated like many of his other concerns. In 2009 his family was a major part of a business coalition that asserted “If we fail to act now, it is scientifically irrefutable that there will be catastrophic and irreversible consequences for humanity and our planet.” Later, when running for President he labeled the issue as a “hoax” and then later, not a hoax. He said “he does not believe it.” At one time he said that the climate will change back again. When Amy Klobuchar spoke in a freezing snow storm, he inferred that this disproves global warming. Trump does not understand that local weather is not relevant to global average temperature increases. Trumps Secretary of State Tillerson urged him not to withdraw from the Paris Climate Agreement. That apparently led to his being fired.

Recent scientific research has indicated that we have about 10 years to make major changes in climate factors, such as burning fuels that send carbon dioxide into the atmosphere. We must spend some money on converting to battery operated cars and converting to cleaner power plants. Our gov must support research and incentives in these areas.  We must also support promising research on methods for removing carbon dioxide from the atmosphere. Time is running out and all possible solutions must be supported.  Please see my previous blogs for more discussions on climate.

 

 

 

 

 

 

 

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.

131. Tech Advances Needed for Survival

8 Dec

I read a wide variety of publications and often find that great technological advances are met with fear and inappropriate limitations. Our planet is rapidly changing by increasing populations and by ignoring important factors like climate change. People are afraid of GMOs, automation, robots, vaccines, DNA innovations, and even medical pills. All of us on Earth are facing very serious problems, and we must rely on reputable science to provide solutions. Below is a brief discussion of three out of the many major issues, which I hope will serve as a stimulus for further research.

GMOs.  I provided detailed info on GMOs in a previous blog (number 87). The simple fact is that nature (without warning us) is constantly changing plant and animal DNA. Evolution selects for survival, not for the human health of a food source. On the other hand, when scientists develop a GMO, we know about it, and it can be tested for health factors. Lets promote GMO evaluation and research, and not abolish them.

CLIMATE CHANGE TECH.  Failure to deal with man-made global warming (see my blogs number 34 and 126) can lead to changes in ocean currents and wind. The consequence will be new patterns of flooding and some normal areas will become deserts. These changes will cause serious hunger problems and horrible mass migrations, unless we deal with these issues in advance. There is research on technology that could reduce the greenhouse gases in the atmosphere, and there are other tech innovations that can help  us. Let’s encourage and financially support tech and scientific research in this area.

ROBOTS AND AUTOMATION.  Many people (particularly workers) are fearful of advances in this area. Consider this: robots and AI are now used extensively in many industries (e.g. auto manufacture), and unemployment in the USA is way down, and there are no other problems of note. Like any other  tech, robots must be programmed and used carefully. In the future, robots could help shorten working times and improve worker safety. 

CONCLUSION: TWO PATHS.  We have serious choices to make. We can put money and effort into new tech and science, or take the negative path. It is very interesting that some in our current gov do not trust experts in climate changes, but do trust experts in military details and weapons development.  Could it be that climate solutions negatively affect greedy rich manufacturers, while the rich and powerful enjoy better weapons to preserve their enterprises.  

Here is what I think! Any tech innovation has some element of risk, which can be minimized by hiring top experts for evaluations. On the other hand, I think discouraging innovation can be much more dangerous.  Worldwide current thinking, if not corrected, can lead to major wars, starvation, worse mass migrations, and horrible increased poverty. Encouraging science/tech education and support is crucial.

 

 

126. Checklist for Personal and Planet Health

7 Nov

For many years I have been studying (1) human health and (2) planet health. I have a strong scientific background so I can learn and understand the relevant concepts, which are constantly changing. This essay is a summary or checklist of things we must do to improve both 1 and 2. I have combined these two, as they are inter-related. All of us can fail to deal with important factors so I have tried to list those that are easy to forget. Everything listed is like the beginning of a path to further knowledge, which you should to explore. Some of the ideas presented are controversial and possibly imperfect, but all are based on published reputable investigations, and extensive personal experience. (In many areas, consultation with doctors and other experts is advised.)

1. Human Health
a. Pay careful attention to what you eat. As you get older, this will become more important. The availability of healthy foods will depend on planetary health discussed below.
b. Limit consumption of all sugars, sugar substitutes, and simple carbohydrates, which the body can rapidly change to sugar. Briefly, the possible dangers are weight-gain, diabetes, heart disease, cancer, migraine headaches, cognitive ability, aging of organs, energy loss, etc. Simple carbohydrates include bread, cereals, pasta, rice, etc. Processed foods often contain harmful ingredients. The internet provides much info on this subject.
c. Limit or eliminate all dairy products, as these will affect your joints. This includes milk (use almond milk instead), cheese, sour cream, yogurt, etc. There are excellent non-dairy substitutes for these. This is most important for people in their 40’s and beyond.
d. Concentrate on eating vegetables and decrease your intake of meat and fish. Too much animal consumption can lead to gout, acid reflux and other problems.
e. Study vitamin supplements and determine what you need. If your doctor says that vitamins often just run through your body, suggesting non-use, ask him/her if they understand what a “catalyst” is.
f. Drink plenty of water, which is vital for health and energy. Water is a key factor in almost every system of the body. For most people, water makes up most of the body. Don’t forget to keep you eyes moist.
g. Most vegetable fats are good for you, while most animal fats should be limited. Olive and some other oils have many health advantages. Sufficient fiber in foods is important.
h. Remember to exercise and stretch major muscles on a regular basis. This muscle work has a profound affect on many aspects of health, including: stress reduction, emotional control, sleep, proper glucose utilization, weight control, many diseases, accident prevention, etc. Even if you are old like me and have bad knees, there still are ways to get good exercise.
i. Most pains in the skeletal system (arms, legs, back, etc) of the body are fully or partially due to inflamation, which is the collection of certain body fluids that aid in healing. Generally, the best method for most areas is application of ice. Other areas, like the back, for example, benefit most from drugs, like Aleve. Back pain often is best resolved with careful, full stretching. I have written several blogs on this.
j. If you have dry skin, rub on moisterizing and restorative lotions.
k. Make sure everything that your body comes in contact with stays clean to avoid bacterial infections.

2. Planet Health for Humans
Your health and survival actually depend much more on planet health than you might expect. Immediately, we can see some common factors. Clean water and air are important for both. Trees provide conversion of CO2 to Oxygen, which is important for humans. Here is a list of environmental factors to work on.
a. Support laws and efforts to avoid water and air pollution. Under appropriate leadership, I think most manufacturers would agree with this.
b. Discourage the abolition of regulations that improve air and water quality. It is easy for rich people to move to safe areas, but many others can really suffer from various types of pollution. One must study history to be aware of these factors.
c. Burning coal and gasoline for warmth and transportation must be limited. We need solar panels, windmills, etc for energy. Cars must be gradually converted to battery operation. This is already possible, it just needs responsible leadership.
d. We need to plant and save more trees, as humans need the oxygen they provide, and they remove the CO2, which affects global warming.
e. GMO’s (genetic modification of plants) must be promoted, along with relevant safety regulation. The Earth’s population is quickly increasing so we will need more food. (Please see my blog on GMOs.) GMOs will also help with climate change problems as they will require less farm equipment energy. Remember that nature is constantly changing the DNA of animals and plants, without notification to us. On the other hand, if scientists develop a new GMO, it is known and can be tested. Our long-term survival will depend on the innovations of scientists.
f. The Oceans of the world are immense and yet they still need our attention. Large populations of fish have substantially decreased due to over-fishing, and oil spills (and pollution) have had great negative effects. Waste matter is filling the oceans and is damaging sea animals.There are many books and essays on this subject.
g. There are many ways to conserve energy, which will become more and more important as population increases and new tech requires increased energy. In our homes we can use low energy light bulbs, efficient furnaces, good insulation, etc. Our cars, factories, farms, etc must be designed for low energy use.
h. Meat requires much more energy to produce than vegetables (about 25 times as much). Scientists are developing methods of growing meat in the lab using DNA manipulations. Eventually, it will be more energy-efficient and less costly than using cattle. I have no problem with this, but some will object. Actually, humans need only a small amount of animal food for good health.
i. Vegetables can be efficiently grown in vertical structures so that they use less land and can be integrated into cities. Use of “vertical farming” buildings will require much less transportation cost and energy, and people will enjoy extra fresh food.
j. Failure to deal with climate change is already producing more hazards like severe hurricanes, droughts, forest fires, and flooding. Climate change causes alterations in worldwide air and sea currents. This can profoundly affect rainfall, so that some areas with normal rainfall will change to deserts and other areas will get too much rain. This will affect food production and will cause massive migration problems, that will make today’s migrations seem trivial.

3. Conclusion
Our planet will not suffer because scientists and technicians have failed to provide better systems to help with adjustments. It will be greedy, callous, and ignorant politicians that will cause disasters for Planet Earth and its inhabitants. There is enough food, clothing, and shelter, for all, and even some room for moderately rich people. Responsible leaders would be able to deal with all the adaptations that are needed.

121. Democrats Do Have Important Messages.

10 Sep

Republicans love to claim that Democrats don’t have positive goals and they are only interested attacking Trump. For example, Sarah Sanders says they “have no message” and only want to “attack people that support this president.”

I have studied politics for many years and I find this assertion to be absurd. Democrats have always promoted the following themes (with a reasonable amount of variation). Here is my version of Democrat goals.

1. All Democrats support improved health care coverage for our citizens.

2. Social programs like Medicare, Medicaid, Social Security, etc. have always been preserved and often improved by Democrats.

3. Democrats support the USA Constitution and traditional governmental institutions, including the FBI, DOJ, and all other executive branch agencies. They also support the authoritative press.

4. Democrats tend to promote the financial success of the middle class and discourage excessive and inappropriate financial support for wealthy people. Democrats favor fair tax programs and elimination of unnecessary subsidies for righ corporations.

5. Democrats believe in the importance of voting rights for everyone who is eligible. Laws that make it difficult for certain people (often low-income) to vote (voter suppression) must be changed.

6. Tax programs and other policies should be designed to increase average income for the non-rich (almost no change), while income has been steadily increasing for the wealthy.

7. Democrats traditionally support NATO and all of our other world-wide allies.

8. Our international trade policies should be designed to help our USA workers in terms of employment and improving their income.

9. Democrats are anti-torture, promote improved gun laws, and favor reproductive “choice.

10. Democrats promote inclusiveness, are against racism, defend the rights of lesbian, gay, and transgender people, and DACA (dreamers).

11. Democrats promote peaceful (and even generous) international relations and agree to war only in drastic situations.

12. Democrats support unions — the right to join them and organize.

13. Almost all Democrats accept American capitalism, but also believe in social programs and certain other limits. There is confusion over the word “socialism.” The few Dems that use this term actually mean support of “social programs” within a capitalistic system.

14. Democrats believe that campaign laws should emphasize equality; and those favoring the rich, like “Citizens United” should be abolished.

15. Democrats support efforts to combat climate change, regulate pollution, promote clean energy, and other efforts relevant to safety for our citizens.

16. Democrats generally support public education, more free education, and federal support for students.

A casual research of Democrat leader speeches and their websites will quickly show that there are many consistent messages and ideals.

In the past two years, Trump has purposely dominated the news with his outrageous tweets and policies so that many Democrat message are obscured. Trump has messages but they are extremely inconsistent, not factual, and change frequently. Most just serve his ego and many like “make America great again” are vague and meaningless. He attacks our basic institutions and our long-term vital allies, who are perplexed by his communications.

96. One Month of Trump

24 Feb

It has been a month since Trump was inaugurated. This blog is concerned with various troubling statements, staff appointments, and other actions. It covers what I see as most significant at this time.

Information Leaks. If a government is doing its job ethically and effectively it has no great fear of leaks. It is leaders that employ tricky or unethical methods that obsess and rant about leaks, and also about the “lying” press. A good government only needs to keep secret certain operations such as diplomatic, intelligence, and military. Sometimes leaks are emphasized to avoid more important issues like a presidential involvement with a foreign country.

Fine-Tuned Government. I don’t think any government is a “fine-tuned” machine given the necessary variety of it’s officials, each with his own ideas and ideals. If everyone agrees and there is fine-tuning, it is likely an authoritarian group of yes-men. A good government needs a variety of opinions from knowledgeable advisors, and reaches a decision based on a consensus or on the best arguments.

Trump Inherited a Mess. Our brave President says that he “inherited a mess.” Hmmm, when he took office, the stock market was way up, the highest it’s ever been. So investors are dancing in the (Wall) streets. The unemployment rate is way down at about 4.8%. The outgoing President Obama has a very high rating, a good indication that there is no mess. There are messes in other parts of the world, but nothing serious here. Since 911, the number of terrorist attacks here have been small compared to other major countries. Perhaps the worst mess is our high prison population. Pres.Obama worked on this but had little cooperation from Republicans. Trump needs to invent messes so that he can heroically clean them up and win the adoration of his poorly educated throng.

A Confused Trump? I only say this in a constructive way, but he appears to be confused and inappropriate. A simple possibility is that he is sleep-deprived and may have a mild early Alzheimer’s disease. Another factor is that most of his life, he has been catered to because of his and his father’s wealth. In the world of business, making money is primary — ideas, ideals, and strict ethics are mostly ignored. Many types of coercion and manipulation are successful and practiced; but are not appropriate or effective for a USA President. His early training emphasized winning, and when confronted and confused, he often reverts back to a description of a winning event. He almost always tries to destroy critics, because he was able to do this in business and limit their effectiveness.

Environmental Protections. If you ask a majority of the people, whether environmental protections are needed for their health and reasonable comfort, most would say yes. Yet we now have an EPA director, Scott Pruitt, that has worked for years against the agency. Very rich folks can find ways to avoid environmental toxins, but millions of American citizens are vulnerable. The wealthy can live far away from industrial polluters where the air is clean, buy expensive water purifiers, have their houses inspected for asbestos, mold, lead, and other toxins. One would have to be very ruthless to allow such dangers.

Loyal Appointees. Having Trump appointees or Republican friends investigate his administration for questionable associations with Russia is like the fox guarding the henhouse.  A primary concern for him is loyal appointees, such as Jeff Sessions as Attorney General, because he needs protection from Congressional investigations.  That protection for Trump and staff was more important than Sessions’ character and bad reputation.

Admiration for Tyrants. Why would a president, who is working for the people, admire the control that certain tyrants (like Putin and Kim Jong-un) have over their citizens. He says they are bad, but praises the way they dominate. There is no value to freedom of expression, criticism, and argument in his mind. He wonders why the press is against him. What intelligent citizen would tolerate his lies/mistakes, his promotion of violence (during the campaign), his impossible promises, his ridiculous bragging, and his pathetic and obsessive attacks on critics.

Relation to Intelligence Units. Can a USA President really function without the support and aid of a fully functional and capable intelligence system? With very few exceptions, these agencies have served Presidents for decades with devotion, honesty and effectiveness. It is only a president that has something to hide, must be in total control, and hires radicals, that cannot work with the established intelligence agencies. (Note, very recently he is doing better with the intelligence units.)

Iran Nuclear Deal. The President would like to abolish the Iran Nuclear Deal, ignoring the fact that many major nations, including China, Russia, France, Germany, and the EU participated in the agreement. Without this deal, Iran would be free to build the bombs — what then? And would our allies still respect us? And who says that Trump could make a better deal. Does he have a long successful record (or any record) of making treaties with other countries? He can only brag and hope.

Climate Change Hoax? The president says man-made climate change is a hoax and he promotes the use of fossil fuels that increase CO2 in the air. He ruthlessly supports industry with the excuse of promoting jobs. A better plan with long-term benefits is to promote alternate forms of energy, more research, and retraining workers that have lost their jobs. The cost is less than flooded cities, rapid changes in drought and rainy areas, and dealing with resulting massive migrations. We will also benefit from cleaner air with more use of electrical energy.

Insidious Corruption. A lot can be said about the past corruption of our government and institutions by Republicans; and Trump may be continuing this process. His cabinet now has several billionaires and major investment firm executives. He is trying to diminish government regulations that keep people safe. He is unlikely to promote the removal of tax loopholes and low tax rates for the very wealthy, which will be costly for the non-rich financially or in reduced benefits from social programs. These are just a few areas of corruption. I detail many other types in my past blogs, and these are also detailed in major newspapers.

Two Messages. When a different message is sent by Trump and one of his staff, who should we believe? One possibility is that Trump really wants to send two messages, one to his loyal supporters and one to world leaders and more intelligent U.S. citizens.  Depending on the current situation, he can refer back to either one: what he said or what, for example, what Mike Pence said. He knows that his original, poorly educated fans, only listen to him.  And I suspect that the best indicator of policy comes from his more reasonable staff. Currently, several of his appointees are knowledgeable and sensible so there is a slight hope for us.
