203. Ocean Science Can Save the World

8 Feb

The oceans cover 71% of the Earth’s surface and contain 97% of the Earth’s water. Ocean researchers say that we know more about our moon than the deep ocean. Recently, there is more concern about oceans as a source of food supply and because of their role in climate-change. As I will describe below, better usage of the oceans can both feed the world and save us from the dangers of global warming.

Johnson and Davis (TED-ED June 2019) and a World Bank Group Report have suggested improvements to ocean farming techniques. Currently, there is an aquaculture, in which many large pens, offshore, are used to hold and grow fish for human consumption. The fish are crowded and stressed. Large concentrated piles of waste result and can lead to disease. Often, breaks in the nets can cause a dangerous release of the penned fish.

It is better to  farm seaweedSeaweed-imageand shellfish. These species have a very low maintenance. The seaweed feed off of sunlight and operators do not need to supply food. The seaweed can be prepared in various ways so as to be more appetizing, can be ground-up and mixed with animal feed, and can also be used as a bio-fuel. Growing seaweed can help with the depletion of fish and can counteract ocean acidification by absorbing CO2.

“Seaweed” is a group of algae that are only found in marine waters (salty sea waters). In terms of  human consumption, it produces algae protein and algae oil similar to soy. It also is a source of valuable omega-3 fatty acids similar to fish oils. There are three different types: red, brown and green.

Growing massive amounts of seaweed can help with global warming.  Seaweed captures CO2, removing it from the atmosphere. A good reference for this  feature is: Tim Flannery, TEDSummit 2019 Can seaweed help curb global warming.”  One problem with this system is that seaweed eventually rots and the carbon is released back into the environment. A solution is to lower the seaweed in the water to a depth where it will best retain the CO2. Scientists are working on various solutions to the release. As research continues, it may be possible to develop seaweed species that are more efficient in using CO2 and in keeping it stored.

There are many publications regarding the depletion of fish in our oceans.  A really good discussion of this is: Jackie Savitz, TEDxMidAtlantic 2013, Save the oceans, feed the worldShe describes how good international regulations can restore depleted species and greatly increase the fish available for increasing populations. 

Angelicque White (TED@NAS, Nov. 2019) writes about microbes in the oceans, that indicate and affect ocean health. When there are major changes such as ocean warming, the microbes are the first affected. 

Ocean microbes are tiny plants and animals that come in a variety of shapes, sizes, and colors. They are at the bottom of the food chain. All animals in the ocean depend ultimately on this basic food source. Microbes absorb CO2 and produce oxygen, so they improve the composition of the atmosphere. 

Climate-change results in warming water, which tends to increase harmful algal blooms. The extra CO2 in the air also leads to ocean acidification, which has many adverse effects on ocean life.  The ecosystem health is generally affected. The changes impact economically important fisheries, like crab and salmon; and also affected are marine mammals like whales, dolphins, seals, and otters. Also important is that warmer waters increase the intensity of hurricanes.

Here are all the climate-change and other ocean problems listed by Angelicque White: harmful algal blooms, ocean acidification, sea-level rise, eutrophication, melting of the polar ice caps, expansion of oxygen minimum zones, pollution, loss of biodiversity,  and overfishing.

My conclusion and main point here, is that ocean science has the potential to help with many world problems. A responsible government will support research in this area.

201. Current Issues, Briefly #7

20 Jan

This is the 7th of a series of blogs with brief discussions of current issues. The material is based on my Tweets (@RichardLeeWB), unpublished thoughts, and descriptions of various publications that I feel are valuable and worth emphasizing.

I just listened to Alan Dershowitz, stating that “abuse of power” is not a high crime. His extensive research trying to understand the thoughts of early leaders is really pointless, and not a justification for this confusion of issues. His problem is that he does not recognize different levels of abuse. Trump’s abuse was very serious, involving elections, delayed military support, and making Ukraine more vulnerable to Russia. Ukraine is like a buffer zone for us, limiting Russian expansion. It is frightening to think that Trump aids in Russian efforts to dominate.

.   Dershowitz Fails to Recognize Different Levels of Abuse-of-power

Famous attorney Alan Dershowitz says that Trump is King, in fact, even more powerful. Well, if Trump is King, then Dershowitz is the court jester. Trumpism is like a disease that infects everyone near him. Star Ken Starr is also participating.

The NY Times just endorsed Amy Klobuchar and Elizabeth Warren. For many years I favored Warren, but recently her arguments with Bernie were a little discouraging. For the last year or so, I have been impressed by Klobuchar, who has high intelligence and good judgement.  I also think that Tom Steyer could make a good candidate and president, if elected. Note, any of the Democratic candidates would be a great improvement.  In the end, whoever gets the most public support is probably going to be our best choice for beating Trump. Another four years of him would be a catastrophe for all Americans.

Rachel Kleinfeld in a 2019 TED talk looks at the relation between politicians, gangs, and police; in an effort to understand high murder rates in certain surprising locals. She writes that several major US cities have very high murder rates. For example, in “New Orleans, more people per capita are dying than in war-torn Somalia.” Throughout the world, there are many small areas that have very high murder rates, surpassing those in wars. The ultimate cause for this, is various patterns of corruption. This TED talk is well constructed and fascinating, and the analysis is impressive.

It seems that every human system in existence for some years becomes corrupted. I just read that drug companies are manipulating patents to limit competition and raise prices.  See this December 2019 TED talk by Priti Krishtel.

Don’t be fooled by the RISING stock market. The market rises when investors believe that major corporations will be profitable. Increased corporate profits generally have little or no effect on middle-class wages. Most important: does a full-time salary cover reasonable expenses?  Also, under President Obama, the market was rising at a steady rate and when Trump took office the market simply continued this rise. Obama had major financial problems when he took office, while Trump had the benefit of Obama’s policies.

Imagine a president that encourages and supports scientific methods for improving our lives; rather than growing military, insulting our allies, withdrawing from worthy treaties, and using government for private enrichment. We need a President that works well with scientists and innovators.

Trump is desperate to win in 2020 because when he leaves office, he is very vulnerable. Briefly, the problem is that investigations of criminality will be easier and likely, tax returns will be revealed. Desperation led to the Ukraine extortion, aberrant  military actions, and other mistakes.

A sure sign of a dictator is that he uses government systems to attack his political opponents. Trump and Republicans have had numerous investigations of Hillary Clinton. The latest three-year investigation found nothing. Six Republican Benghazi investigations found nothing. These unethical investigations are not consistent with our traditional American values.

Major World problems are: climate-change and food-supply. Both can be solved with improved laws and methods for ocean fishing and policies. See TED Talks by Johnson & Davis: “Underwater farms vs climate change“.  And, see Savitz: “Save the oceans, feed the world.” National leaders must understand and use science to solve many of our problems, like depletion of fish and acidification of oceans. The same methods for increasing ocean food-supply, also help with global warming.

To Adam Schiff: Dedicated people like you should be proud to receive Trump insults. I would like to see a website that provides a medal for the most vicious Trump abuse. Adam, you are so effective and patriotic that he must attack. Keep up the great work.

Candidate Tom Steyer is becoming a top contender for US President. It is true that he has 1.6 billion and is spending much on his campaign. But that isn’t a negative because he has spent the last 9yrs on worthy causes, like climate-change and health care. Tom Steyer is a good choice.

How many Republican voting citizens have essentially said that domestic factors are great under Trump and the international policies don’t matter much. Well, Trumps disastrous dealing with Iran, which started with withdrawal from the Iran Nuclear Deal, brings us close to a major war.

If you like people that really tell it like it is, then Steve Schmidt is your man. Earlier, he was a major Republican strategist. Starting June 2018, he has forcefully denounced the Republican party and Trump, in graphic terms. I also like the honesty in Morning Joe, and others.

Considering all aspects of the Iranian military leader assassination, it seems the dangers somewhat exceed the benefits. First, killing one official does not change government goals or policies. Second, Trump acted alone, ignoring Congress and allies. Third, major retaliation is likely. 
The Iran Nuclear Deal according to those involved, was working properly. But Trump, who is obsessed with winning and proving his superiority, decided to abandon it and impose more powerful sanctions. As a result, military actions are increasing and we are closer to war. Trump should have worked with allies on improving the treaty, rather than abandoning it. One reason for this serious mistake is that Trump’s unethical history requires him to find loyalists rather than competence.  Note that money given to Iran was mostly frozen assets that belonged to them. Some money was interest on a debt.

 

 

 

191. Voters: Don’t let Trump Mislead you Again

15 Nov

It pains me to think that many voters have believed the false promises of Donald Trump, and in 2016 voted for him. Here is a list of his lies and distortions of facts that must be considered.

Trump said that when he took office, there would be a new Republican health care system that would replace ObamaCare. There was no Republican system and he and Republicans were going to abolish ObamaCare without a replacement. Fortunately, John McCain, by his one vote, saved us from a disaster.

Trump mislead voters about the wall for our Southern border. He did not say the truth, that a wall could only be built if the Congress approved it, and he did not say that Mexico was not likely to pay for it. He lied when he said it was the best plan for that immigration problem.

Trump told voters that he was so rich that he would never need to accept money from donors. A few months later, he started to do just that. He actually was not that rich and had to borrow money to survive. American banks did not trust him, but he managed to get loans from a foreign bank.

Trump said he would drain the swamp, but instead he swam in it. He hired billionaires from Wall Street. Most of his staff  and appointees were hired on the basis of loyalty, rather than expert knowledge and experience. He and his staff supported big business rather than the ordinary people that voted for him. His policies have produced a massive national debt, partially due to major permanent tax reductions for millionaires. He gave the middle class small temporary reductions. Also swampy is Trump’s profits from businesses he illegally promotes through his presidency. He even wanted (for a while) to have an international meeting at one of his golf clubs, Doral.

He promised to abolish regulations, but did not tell you that regulations are mostly for the safety of ordinary people, while rich manufacturers, of course benefit. There is a long history in the US of  toxins produced during manufacturing, that have killed many people.

Trump promised improved trade policies. What he did was poorly planned and damaged farming and other businesses both here and abroad. The final effect was small successes and major failures. He did not consider that every tariff he imposed could be matched by a foreign tariff. He lied that tariffs are paid by the foreign countries. A US tariff is paid by US importers and usually results in higher US prices.

Perhaps most serious of all, is that he mislead you on the dangers of global warming. Aberrant weather patterns due to climate change are already causing floods, fires, and farming problems. These dangers will soon become more widespread and will lead to major population migrations. Desperate people will likely cause wars and increased crimes.

He promised at times to become more “presidential” but, in fact, he still calls people names, has a ridiculous, large turnover in staff, and governs by whims expressed in tweets. He is more interested in personal winning than in the success of our country. Trump is in favor of torture (Pres. Ronald Reagan opposed this) and cares little for human suffering.

Maybe the real issue for many Trump supporters is that they like his policy of rejecting Mexicans, Muslims, and others. They will have to weigh these policies against all the harms that Trumps other policies will cause.  Also note that achievements touted by Trump, such as a rising stock market and low unemployment, were continuations of  remarkable eight-year trends established by President Obama.

 

 

 

 

 

 

187. Climate-Change: Worthy Research Projects for Support

13 Sep

Our US government is ignoring Climate-Change dangers. I am hoping that wealthy people and corporations will make up for this by supporting research in this area (and in other ways). Below, I have listed some worthy projects.  

Briefly, global warming is dangerous and can result in fires, floods, and starvation. It is caused by increased amounts of heat-trapping greenhouse-gases (mostly carbon dioxide and methane) in the atmosphere. Almost all solutions are directed to reducing these gases, which occur naturally, but are increased by human burning of fossil fuels (coal, gasoline, etc.) in power plants, cars, planes, and by other human activities.

Seehttps://climate.nasa.gov/solutions/adaptation-mitigation/

Here is a summary of basic solutions:  

1. Reduce the flow of greenhouse gases into the air, where they trap heat and cause global warming. Limit burning fossil fuels, like coal and gasoline, for power. It is vital to stop these gases from increasing. Small increases in average global temperature have a profound effect — just a two or three degree increase can cause colossal effects.

2. Enhance the absorption of greenhouse gases by oceans, forests, and soil so that they are removed from the atmosphere.

3. Remove the greenhouse gases from the atmosphere by the development of industrial processes.

4. Work on the efficiency and cost of alternate energy, such as wind and solar, so that fossil fuels are not needed.

Some specific solutions:

Improved batteries will enhance the use of wind and solar methods for production of electricity. If wind speeds drop and the sun isn’t shining then batteries can be used to store power for use under negative conditions. Good batteries will also promote the use of electric cars. There is considerable research in this area and much is supported by auto industries.

Planting trees and preserving forests are very helpful for absorbing carbon dioxide in the air, but other methods are still required.

Black carbon (soot) results from incomplete burning of fuels or wood. There is research that suggests it makes global warming worse, and solutions are being studied. Also studied are the effects of ozone in the air. Reseachers believe that reducing soot and ozone could be very effective in conjunction with other methods.

There is research on reflecting light from the sun to reduce heat, by pumping aerosols  into the stratosphere. Similarly, reflections of sunlight could be accomplished by making  the earth more reflective. Vegetation (trees, plants, etc) could be altered to make them  reflect more light. There are various other similar solutions that are being considered.

A University of California biogeochemist, Asmeret A. Berhe, has suggested that
alterations of soil could affect its carbon-trapping power. Many human activities have led to the degradation of soil so that its ability to help with climate change is affected. The solution would be to vary farming and forestry practices.
See: https://www.ucmerced.edu/content/asmeret-asefaw-berhe

It is argued by researchers that using “restorative ocean farming” could help with climate change and also provide safer and better seafood. Most current seafood farming methods are generally harmful to the oceans. Avoiding sea “pens” for fish, and using more natural ocean enhancement could be good for health and climate-change.
See TED, June 2019: Ayana Johnson and Megan Davis: “Could underwater farms help fight climate change?”

Joanne Chory (https://www.salk.edu/scientist/joanne-chory/) has been researching how improved plants could be helpful. Adaptable “supercharged plants” could be developed that absorb more carbon, deeper underground, and for many more years. The program is the Salk Institute’s “Harnessing Plants Initiative.”

It has been proposed, that climate-change could be attacked with a method that creates useful energy. Natural gas could be used to generate electricity in a way that takes carbon dioxide out of the air. (See TED April 2017, Tim Kruger)

“Chemical engineer Jennifer Wilcox previews some amazing technology to scrub carbon from the air, using chemical reactions that capture and reuse CO2 in much the same way trees do.” This TED talk (April 2018) provides an excellent summary of many efforts to develop massive reduction in atmospheric CO2. It should be noted that researchers generally consider that any one method dealing with climate-change will not be enough, and that a combination of several of the best methods is required.

Ted Halstead (TED talk April 2017) describes a plan that would break through various  barriers to climate-change solutions, and would appeal to businesses and Republicans. The “carbon dividends” plan involves a gradually rising carbon tax, and dividends given to the public. This plan was presented to Pres. Trump two weeks after his  inauguration. It was widely endorsed at that time, but apparently, after two years, it was not implemented.

 

 

183. The “Trump Experiment” Failed

9 Aug

After about 930 days in office, it is now more than obvious that the “Trump Experiment” has failed and we must do everything possible to protect our nation. There are three actions, with which to move forward: (1) Impeach, (2) Nullify, (3) Wait for the 2020 election. I believe that we should do everything possible in all three areas: full speed ahead on impeachment, nullify him in every way possible, and develop the best strategies for the election. Nullification includes various methods of preventing dangerous acts, such as California car milage regulations that override Trump’s rule.

I believe that our citizens need brief, clear statements of Trump’s failures so that they can effectively more forward.  Before continuing, I will acknowledge that a small number of Trump’s actions were beneficial, but usually were not significant. Here is my list (also see my previous blogs).

Failure to acknowledge global warming and to provide badly needed leadership in this area. There was a failure to provide international encouragement, relevant research funds, and to support exemplary efforts in industrial actions. The internet is full of info regarding this subject. This is a very serious problem and is recognized by the vast majority of nations

Failure to govern with dignity, morality, and reliability. Trump withdrew from several existing treaties and international agreements. He has failed to provide the promised improvements. Other nations now hesitate to form agreements with us because of his history of breaking agreements.

Trump often (thousands of times) lies, makes mistakes, and re-writes history according to his own agendas.

Trump has undermined our policing and intelligence agencies so that they can be influenced by his policies and agendas (see previous blog, 182). This is a clear and serious action, which is on the path to tyranny. The US Attorney General Barr is not independent and acts as a yes-man.

Trump has lied about his international tariffs: he says that the foreign countries pay for the tariffs, when it is the US importers that pay and pass on losses to our consumers. His trade policies overall have not been effective and other countries have countered our tariffs with their own. Resulting trade problems have seriously affected our farmers and manufacturers. Trump has not considered all of the possible negative effects of his policies. An important point is that he has tried to work alone, ignoring allies. For example, a group of nations would have been much more effective in dealing with China abuses.

The Trump administration is poorly coordinated and engages in petty quarrels. Calling other US leaders childish names does not engender respect. He is often at odds with his cabinet members and other staff.

Trump has admitted to favoring torture, and his policies regarding our Southern border illustrate his cruelty. He clearly supports racism and promotes hatred.

Trump did not “drain the swamp,” but swam in it. His staff includes wealthy Wall Street icons. His cabinet members were chosen from those opposing the goals of their agencies. He has encouraged the removal of regulations that protect us from pollution and toxins. A shocking number of his staff have been indicted for criminal actions. He has secret meetings with US adversaries, such as the Russian Putin. He has attacked our allies and NATO.

 

 

 

 

 

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.
