The Evidence for Rapid Climate Change

My last post, “Why We Badly Need a Revenue Neutral Carbon Tax” makes the case for combatting global warming with a sensible free market mechanism such as a carbon tax rather than a hodge-podge of arbitrary national and state regulatory actions. Since many of the Facebook responders to this post deny the reality of global warming in the first place, I have decided to present the overwhelming evidence for its existence.
When ninety-seven percent of climate scientists worldwide agree that climate change is real and they have assembled a massive amount of measurement data to back up this claim, I think we have to take them seriously. For example:

  • The Global Surface Temperature is Rising. Global average temperature has risen 1.4 F since the early 20th century as shown in the chart just below which also shows the close correlation with carbon-dioxide concentration.
    Capture2
  • The Sea Level is Rising. It has risen at an average rate of 1.7 mm/year over the last 100 years and at the rate of 3.5 mm/year since 1993 which is equivalent to one inch every seven years.
  • Global Upper Ocean Heat Content is Rising. The top 700 meters have warmed by .3F since 1969. Thermal expansion of the ocean water as it warms contributes to the sea level rise.
  • Glacier Volume is Shrinking Worldwide. Just Greenland and Antartica alone have lost at 150 cubic kilometers of ice annually in recent years.
  • Declining Artic Sea Ice. Both the extent and thickness of artic sea ice has declined rapidly over the last several decades (see chart below).
    Capture1I accept the reality of the scientific evidence for global warming but I am certainly no “alarmist” in terms of what our response should be towards addressing it. It will be many, many years before renewable energy sources like wind and solar are able to make a substantial dent in worldwide energy needs.
    The best thing to do in the meantime is to attempt to decrease carbon dioxide emissions from fossil fuels through carbon capture and storage. A carbon tax would create a huge economic incentive for the coal and oil industry to solve this problem. If and when they figure it out, it is likely that the technology involved would rapidly spread around the world.
    This would represent a real solution to a very serious problem.

Why We Badly Need a Revenue Neutral Carbon Tax

A large and steadily growing majority of Americans believe that global warming, caused by the burning of fossil fuels, is a serious problem which must be addressed. What remains is to figure out how to do this with the least possible amount of economic damage to ourselves and others.
Capture1Consider that:

  • Energy consumption will increase 56% worldwide by 2040, overwhelmingly with the use of fossil fuels. Biofuels are a very inefficient source of energy and wind energy isn’t much better. Solar energy is dropping in price but is still much more expensive than natural gas.
  • The Environmental Protection Agency has just issued its Final Rule for a Clean Power Plan to reduce carbon emission levels in 2030 by 32% below 2005 levels.
  • California is now considering drastic legislation requiring a 50% reduction in petroleum use by 2030 which is likely to do much damage to the California economy.
  • In 2008 the Canadian province British Columbia introduced a revenue neutral carbon tax which has succeeded in reducing carbon emissions without damaging the BC economy.
  • The advocacy group, Washington Carbon, is trying to put a carbon tax on the Washington State 2016 ballot. Initiative Measure 732 would institute a tax on fossil fuels of $25 per ton of carbon dioxide. According to the Seattle Times many environmentalists are opposed to this initiative because it would be revenue neutral!

Conclusion: humanity is faced with the very serious problem of global warming and the response so far is chaotic and totally inadequate. The developing world is rapidly increasing its use of fossil fuels while the EPA is trying to put the brakes on our own use. Meanwhile states (and Canadian provinces) are establishing their own individual energy policies.
Isn’t it clear that what is needed is a conceptually simple unified approach to create incentives for all of us to cut back on carbon dioxide emissions? Isn’t it also clear that the best way to do this is with a national carbon tax?
It is up to the U.S. and other developed countries to take the lead in doing this. Once we are clearly doing what is needed, then and only then can we begin to lean on less developed countries to follow our example.

 

 

Climate Change Requires N2N

I have been reporting for several days on a fascinating new book, “Smaller Faster Lighter Denser Cheaper” by Robert Bryce and, in particular, what it means for climate change.
CaptureHere are some key points:

As Mr. Bryce says, “It’s time to focus our inquiry on the key question: if we agree that too much carbon dioxide is bad for the Earth’s atmosphere – what are we going to do? What’s the best “no regrets” climate policy as we move forward?” Here’s how to proceed:

  • We will need much more energy in the decades ahead in order to raise the living standards of the more than two billion people who are still living in energy poverty.
  • Hydrocarbons now provide 87% of the world’s total energy needs. There are still no affordable, scalable substitutes for the vast quantity of hydrocarbons that we use today.
  • People in the industrialized countries cannot and should not hinder the efforts of the world’s poor to gain access to cheap, reliable sources of energy.
  • We must give a very high priority to adapting and hardening our cities, networks and structures so they can better survive severe weather events.
  • N2N (natural gas to nuclear) provides the best no-regrets energy policy because those fuels can provide significant environmental benefits with relatively low economic costs.
  • The combination of natural gas and nuclear energy has reduced America’s carbon footprint by 54 billion tons over the last six decades. By comparison, wind, solar and geothermal sources reduced emissions by just 1.5 billion tons over the same period.

In other words, we need to be practical about the new sources of energy which will be needed to meet growing world demand. Renewable energy sources cannot nearly provide what is needed. Exploiting the current abundance of natural gas while further developing nuclear energy is the best way to proceed.

Smaller Faster Lighter Denser Cheaper

I look at a lot of books and every once in a while I find one that I really like. Such is the case for “Smaller Faster Lighter Denser Cheaper”  by Robert Bryce, a scholar at the Manhattan Institute.
The book starts out: “We are besieged by bad news. Climate change, pollution, famine, water shortages, war and terrorism, the mess at Fukushima, political gridlock, and the ongoing debt problems and economic malaise in Europe and the United States are dominating the headlines.” This leads some people to embrace “collapse anxiety,” the feeling that our problems are so great that our prosperous Western lifestyle cannot be sustained and soon may crash.
Capture“This pessimistic worldview ignores an undeniable truth: more people are living longer, healthier, more peaceful, lives than at any time in human history. Amid all of the hand wringing over climate change, etc. the plain reality is that things are getting better, a lot better, for tens of millions of people around the world.”
“Dozens of factors can be cited for the improving conditions of humankind. But the simplest explanation is that innovation is allowing us to do more with less. We are continually making things Smaller Faster Lighter Denser Cheaper.” Computers are becoming smaller and faster. Nearly everything we use is getting lighter. Our engines and farms are getting denser. Innovators are driving down costs and making goods and services cheaper.
For example, how does the SFLDC perspective apply to energy use?

  • In July 2012 blackouts hit northern India leaving 600 million people without electricity, even though India’s coal use doubled between 2002 and 2012. India relies on coal for 2/3 of its electricity production and has enough coal reserves to last a century. In India and worldwide, coal use will almost surely continue to increase.
  • Consider the following power densities (footprints) of various forms of energy:
    i) biofuels: .3 watts per square meter
    ii) wind energy: 1 watt per square meter
    iii) solar photovoltaic panels: 6 watts per square meter
    iv) oil well: 27 watts per square meter
    v) natural gas: 28 watts per square meter iv) nuclear plant: 50 watts per square meter

Conclusion: From a power density point of view biofuels are a very inefficient source of energy and wind energy isn’t a whole lot better.
What is the best energy policy going forward? Stay tuned!

The Slow Growth Economy We’re Stuck In

We have very high debt and Paul Krugman says in “Debt Is Good” that we need more! The Congressional Budget Office’s latest report this week, “An Update to the Budget and Economic Outlook: 2015 – 2025” predicts slow economic growth for the next ten years, averaging 2.1% per year (see chart below).
CaptureUnfortunately, high debt and slow growth are a deadly, self-reinforcing, combination. Today’s Wall Street Journal has a chart (pictured below) showing clearly how budget deficits are likely to increase over the next ten years. The public debt (on which we pay interest) is predicted to grow from 74% of GDP today to 77% of GDP in 2025, increasing by a total of $7 trillion over this time period.
Capture1Here is another connection between slow growth and high debt:

  • Slow Growth means higher than necessary unemployment and under-employment as well as minimal raises for employed workers. The resulting economic slack leads to
  • Low Inflation. But low inflation means that the Federal Reserve can maintain
  • Low Interest Rates to try to encourage more borrowing to stimulate the economy. This means, in turn, that Congress can run up huge deficits without having to pay much interest on this almost “free” money. This eventually leads to:
  • Massive Debt. But what happens when inflation does take off, which has happened before and is likely to happen again? Then the Federal Reserve is forced to raise interest rates quickly and we are stuck with huge interest payments on our accumulated debt. And meanwhile entitlement spending on Social Security, Medicare and Medicaid is also growing rapidly. At this point debt increases very rapidly which leads to a severe
  • Fiscal Crisis.

Of course things don’t have to happen like this. Congress might become more responsible and either cut spending and/or raise taxes and start shrinking our huge deficits. Or perhaps slow growth really is the new normal and interest rates will remain low indefinitely. But slow growth is not pain free; there are many millions of unemployed and under-employed Americans who want to work and whose lives are stunted otherwise.
Slow growth is a very destructive path to be following. We badly need to adopt policies to speed it up!

Paul Krugman: “Debt Is Good”

Every Monday and Friday morning when I pick up the New York Times, I immediately turn to the OP-ED page to see what liberal icon Paul Krugman is saying. In his most recent column, “Debt Is Good,” he says that “what ails the world economy right now is that governments aren’t deep enough in debt.”
CaptureHere is my response to his argument:

  • “The federal government can (now) borrow at historically low interest rates. So this is a very good time to be borrowing and investing in the future.” Our public debt (on which we pay interest) is now $13 trillion or 74% of GDP, the highest since the end of WWII, as shown in the above chart from the Congressional Budget Office. It is likely that interest rates will soon begin to go up. Every 1% rise will increase interest payments on our already existing debt by $130 billion per year. Where are the hundreds of billions of new dollars for debt service going to come from in an already tight budget? The more we add to the debt, the worse this problem will become.
  • “Having at least some government debt helps the economy function better.” I agree! But $13 trillion is way beyond what is needed for this. It is outrageously excessive!
  • “What we need are policies that would permit higher (interest) rates in good times without causing a slump. And one such policy would be targeting a higher level of debt.” The problem here is the conceit of Keynesians, like Mr. Krugman, that monetary policy alone can restore us to economic and fiscal health. Rather than accepting that the economy has entered a “new normal” with a permanently slow growth rate of about 2% (as has been the case since the end of the Great Recession in June 2009), we need policy changes such as individual and corporate tax reform (revenue neutral to be sure) and changes in the Affordable Care Act and Dodd-Frank Act to remove their job killing features.

 

Anybody with an ounce of common sense knows that excessive borrowing will eventually lead to disaster. Mr. Krugman seems to think that by constantly ridiculing his opponents, he can get away with denying this simple truth.

Debunking Several Social Security Myths

The Committee for a Responsible Federal Budget has just published a new report, “Debunking 8 Social Security Myths on Its 80th Birthday.” Here are several of the “myths” they report on:

  • Myth: Social Security does not face a large funding shortfall. Fact: Social Security’s trust funds are projected to run out of reserves within 20 years. Although the Social Security Trust Fund currently contains $2 trillion, it is being depleted at a rate of close to $100 billion per year. The looming insolvency is a result of the growing costs associated with an aging population.
  • Myth: Today’s workers will not receive Social Security benefits. Fact: Even if policy makers do nothing, the program will still pay about three-quarters of scheduled benefits. Once the trust fund is depleted, benefits would be paid only from incoming payroll tax revenue.

    Capture

  • Myth: We don’t need to worry about Social Security for 20 years. Fact: there is a very high cost involved in waiting to reform Social Security. Substantial changes are needed to avoid the benefit cuts referred to above. The sooner we make these changes the less onerous they will be for both recipients and payroll tax payers (see above chart).Capture1
  • Myth: Social Security reform is code for slashing benefits, especially for the poor. Fact: under most reform plans, benefits would continue to grow faster than inflation. Most reform plans do not cut benefits from their current levels but rather slow the growth of benefits to reduce some of the pressure that wage-growth and rising life-expectancy place on the program. Under the Simpson-Bowles Plan, for example, benefits for low-wage earners will grow much faster, proportionally, than for higher-wage earners (see above chart).

Conclusion: It should be clear from the above discussion that Social Security can be fixed so as to continue to provide retirement benefits indefinitely into the future. It should also be clear that the sooner the needed reforms are implemented the less painful they will be for all concerned. We should tell our Congressional representatives that we want them to act now!

Minorities and Higher Education: a Severe Dilemma

In two recent posts, here and here, I have established that:

  • Rapid increases in federal student aid in recent years have led to tuition increases at both public and private educational institutions and for both undergraduate and graduate students.
  • American higher education is increasing the divide between the haves and the have-nots in the sense that college degree attainment is increasing much faster for those students from higher income families.
  • Furthermore, students at private, nonprofit (most prestigious) institutions have higher graduation rates and lower debt levels compared to students from public institutions who, in turn, have both higher graduation rates and lower debt levels than students at for-profit colleges (least prestigious).Capture

As if this isn’t bad enough, it gets even worse! The Federal Reserve Bank of St. Louis has just reported, “Why Didn’t Higher Education Protect Hispanic and Black Wealth?” that “White and Asian college grads do much better than their counterparts without college, while college-grad Hispanics and blacks do much worse proportionately.” (see above chart).
In short, the federal government is spending more and more money on higher education, which, in turn, is making colleges and universities more and more expensive. Whites and Asians from higher-income families are graduating in much higher numbers and with minimal debt, while college-grad blacks and Hispanics are mired in huge levels of debt.
How should society address this severe inequality in higher education?

  • Federal student loans should be limited to $30,000 for undergraduates and $60,000 for graduate students, the average amounts borrowed today for each category of student. Beyond these limits, students could still borrow from the private market, but with no subsidies or loan guarantees provided by the government. This single action alone will help to hold down college costs.
  • All students, and especially those from low-income families, should be encouraged to avoid excessive college debt. There are many high quality, low-cost educational institutions all around the country (e.g. UNOmaha where I teach) to meet their needs. It should be strongly emphasized that an expensive, prestigious institution is not needed to obtain a good education.

A Vivid Example of Fiscal Irresponsibility at the Federal Level

An article in the Friday, August 14 edition of the Omaha World Herald, “Why are the BRT stations so expensive? Officials explain the $260,000 price tag,“ describes a new $30 million bus rapid transit plan for Dodge Street with 27 individual sleek, modern bus stop shelters along the route at a cost of $260,000 each.  Half of the new $30 million plan will be paid for by the city of Omaha and half by the Federal Transit Authority which has an annual budget of $8.6 billion.
Capture1 The issue is not whether Omaha should spend $15 million in local funds to achieve a $30 million bus system upgrade. We can expect city officials to make a responsible decision on this matter. The real issue is why the FTA should have annual budget of $8.6 billion to begin with when it is paying for, and therefore encouraging, extravagantly designed bus transit systems all over the country.
CaptureThe U.S. deficit for the 2015-2016 budget year, ending on September 30, is predicted to be about $450 billion dollars. This adds to the approximately $13 trillion public debt (on which we pay interest) which, at 74% of GDP, is the highest it has been since the end of WWII (see the above chart from the Congressional Budget Office).
It is the responsibility of Congress and the President to figure out how to get the budget under better control. All aspects of federal spending can and should be tightened up, including entitlements (Social Security, Medicare and Medicaid) and discretionary spending (everything else).
The Federal Transit Administration is wasting money on unnecessarily extravagant bus transit systems. Such fiscal irresponsibility means that its budget should be cut significantly. Many other similar examples exist in the federal government. We need people in Congress who can identify these fiscal boondoggles and effectively agitate for needed cutbacks.

How to Avoid a New, and Much Worse, Financial Crisis

Is it possible for the U.S. to effectively address its enormous debt problem in today’s contentious political environment? Two weeks ago I discussed in “America’s Fourth Revolution” why the political scientist James Piereson thinks this is impossible. He is very persuasive but I think he is too pessimistic.
CaptureSince then I have discussed several different things we should do to turn around this perilous situation:

  • If spending for just Medicare and Medicaid (two very expensive entitlement programs) alone fell by 25% over ten years, as a percentage of GDP, and then stayed in line with GDP after that, the U.S. would actually have a budget surplus in 2040.
  • Just recognizing the magnitude of our debt problem would do wonders in public awareness.
  • If the Tea Party were able to grow beyond a protest movement and unite the country behind a majoritarian agenda of work, mobility and opportunity, it would be much more effective in achieving its fiscally conservative goals.
  • Another significant way to save money, and get better results at the same time, is to turn over more and more programs to the states. A good way to do this is with block grants to the states for federal programs in such areas as welfare, education and Medicaid. This would give the states more flexibility to get the job done in an efficient and cost saving manner.

What we need to do to turn our debt situation around is to greatly shrink our annual deficits below their current level of about $450 billion per year. If the debt is growing slower than the economy, then it will shrink as a proportion of the economy. This is what happened after WWII (see above chart) and it needs to happen again now!
