Will global warming alarmism undermine the authority of science?

Leave a comment

This is a must read article from Forbes magazine about a new paper in an Australian journal by Garth Paltridge. Dr. Paltridge is an Australian atmospheric physicist who holds a BSc from the University of Queensland, a PhD from University of Melbourne and a DSc from the University of Queensland.

The article introduces the author and his thesis:

Will the overselling of climate change lead to a new scientific dark age? That’s the question being posed in the latest issue of an Australian literary journal,Quadrant, by Garth Paltridge, one of the world’s most respected atmospheric scientists.

Paltridge was a Chief Research Scientist with the Commonwealth Scientific and Industrial Research Organization (CSIRO).  The latter is Australia’s equivalent of the National Science Foundation, our massive Federal Laboratory network, and all the governmental agency science branches rolled into one.

Paltridge lays out the well-known uncertainties in climate forecasting. These include our inability to properly simulate clouds that are anything like what we see in the real world, the embarrassing lack of average surface warming now in its 17th year, and the fumbling (and contradictory) attempts to explain it away.

Paltridge writes:

“The trap was fully sprung when many of the world’s major national academies of science (such as the Royal Society in the UK, the National Academy of Sciences in the USA and the Australian Academy of Science) persuaded themselves to issue reports giving support to the conclusions of the IPCC [the United Nations’ Intergovernmental Panel on Climate Change]. The reports were touted as national assessments that were supposedly independent of the IPCC and of each other, but of necessity were compiled with the assistance of, and in some cases at the behest of, many of the scientists involved in the IPCC international machinations. In effect, the academies, which are the most prestigious of the institutions of science, formally nailed their colours to the mast of the politically correct.

[…]“In the light of all this, we have at least to consider the possibility that the scientific establishment behind the global warming issue has been drawn into the trap of seriously overstating the climate problem—or, what is much the same thing, of seriously understating the uncertainties associated with the climate problem—in its effort to promote the cause. It is a particularly nasty trap in the context of science, because it risks destroying, perhaps for centuries to come, the unique and hard-won reputation for honesty which is the basis of society’s respect for scientific endeavour.”

None of this is a surprise to Christian apologists, because we’ve been through this before with Darwinism. Yes, it really can happen that science is hijacked by religious people who want to support their ideologies. Science is wonderful, but it’s not immune to being abused.

Forbes also posted an excellent long article re-capping how climate scientists manipulated data in order to prove what they wanted to prove. This article takes about the Climategate scandal, which is useful  to show how far these scientists will go.

My conversation with a leftist friend about basic economics and rent control

3 Comments

My conversation with a leftist friend about “Basic Economics: A Common Sense Guide to the Economy, 4th Edition“, by Thomas Sowell.

Him: I remember why I stopped reading that book when you asked me to read it.

Me: Why did you stop reading it?

Him: Because of the chapter on rent control.

Me: Chapter 3 is the chapter on price controls. It talks about rent control.

Him: I expect an economist to present both sides of rent control. He has to present the arguments for and against rent control.

Me: There are not two sides to rent control. There is only one side to rent control. He chose that because it is a clear cut example of the problems caused by price controls. Economists universally condemn rent control, across the ideological spectrum.

Him: No they don’t.

Me: The chair of the Department of Economics at Harvard University, Greg Mankiw, reports in his economics textbook that 93% of professional economists agree that rent control reduces housing supply and housing quality. It is the most agreed upon position among economists across the ideological spectrum, number one in his list of facts on which professional economists agree. And obviously they have reasons for agreeing on that, specifically the experience of trying rent control policies in different times and places. It has always failed.

Him: Somebody must like rent control, because they have it in New York city.

Me: Politicians and low-information voters support rent control. It makes politicians feel good, and it gets them elected, too – if the voters are economically illiterate enough, as they are in New York city.

Him: But what about global warming then? Isn’t the consensus against you there?

Me: There has been no global warming in the last 17 years, according to the New York Times. They were reporting on findings by the UN IPCC in 2013.

Him: The UN never said that. The New York Times never wrote that.

Me: Yes, they did. And I have the sources I can send them to you.

Him: I’ll bet you do. (walks away in a huff)

This is the relevant quote from the Greg Mankiw post from his survey of economists that appears in his textbook:

  1. A ceiling on rents reduces the quantity and quality of housing available. (93%)
  2. Tariffs and import quotas usually reduce general economic welfare. (93%)
  3. Flexible and floating exchange rates offer an effective international monetary arrangement. (90%)
  4. Fiscal policy (e.g., tax cut and/or government expenditure increase) has a significant stimulative impact on a less than fully employed economy. (90%)
  5. The United States should not restrict employers from outsourcing work to foreign countries. (90%)
  6. The United States should eliminate agricultural subsidies. (85%)
  7. Local and state governments should eliminate subsidies to professional sports franchises. (85%)
  8. If the federal budget is to be balanced, it should be done over the business cycle rather than yearly. (85%)
  9. The gap between Social Security funds and expenditures will become unsustainably large within the next fifty years if current policies remain unchanged. (85%)
  10. Cash payments increase the welfare of recipients to a greater degree than do transfers-in-kind of equal cash value. (84%)
  11. A large federal budget deficit has an adverse effect on the economy. (83%)
  12. A minimum wage increases unemployment among young and unskilled workers. (79%)
  13. The government should restructure the welfare system along the lines of a “negative income tax.” (79%)
  14. Effluent taxes and marketable pollution permits represent a better approach to pollution control than imposition of pollution ceilings. (78%)

And this is the relevant quote from the New York Times article, dated September 2013:

The global warming crowd has a problem. For all of its warnings, and despite a steady escalation of greenhouse gas emissions into the atmosphere, the planet’s average surface temperature has remained pretty much the same for the last 15 years.

As you might guess, skeptics of warming were in full attack mode as the Intergovernmental Panel on Climate Change gathered in Sweden this week to approve its latest findings about our warming planet. The skeptics argue that this recent plateau illustrates what they always knew — that complex global climate models have no predictive capability and that, therefore, there is no proof of global warming, human-caused or not.

The author of the NYT article (a leftist) goes on to attempt to explain he is not concerned by the 17 year period of no significant warming, but the point is that the 17 year (not 15 year) period of no significant warming is A FACT acknowledged by the UN IPCC that has to be explained by those who believe in catastrophic man-made global warming. The IPCC may not like the temperature measurements, but those facts are not in doubt. The global warming crowd might make predictions about the future, but they made predictions about the past before, and we now know for a fact that those predictions (polar ice caps melting, Himalayans melting, significant global warming, etc.) were FALSE. They have been falsified by evidence, and that’s not in doubt.

Economic illiteracy is the problem

When people on the left voted for Barack Obama in 2012, they did not know based on evidence that they could keep their doctors and keep their health plans and that insurance premiums would drop $2500. They did not know it because the economic studies contradicted Obama’s words. They even believed Obama when he said that the Benghazi incident was caused by a Youtube video. Obama-supporters had a sincere belief in the words of his passionate speeches. They were impressed by the visuals of him talking to large crowds of young people. They believed him because they had feelings about him. And voting for him made them have good feelings about themselves. They felt that they were going to achieve good things by voting for this good man. They meant well, but they did not know. They did not have evidence.

Before the 2012 election, people on the right pointed to evidence from studies (like this one) showing that Obama was lying, but his supporters were apparently not interested in economic studies. They want to preserve the feelings of being good people. They want to preserve the belief that you can embrace policies that sound good, and that words that sound good will necessarily lead to good results for people who are at a disadvantage. I don’t question the motives of people on the left – they mean well. But meaning well doesn’t produce good results without knowledge of economics. In economics, policies that sound appealing to well-meaning liberals (rent control, tariffs, protectionism, minimum wage, trillion-dollar deficits) actually produce bad results for poor people. And we know this for a fact from our experience across different times and places.

If we can get people to accept the authority of our observations of policy experimentation in different times and places over and above their feelings and intuitions, then we can save this country.

Intelligence reports show Islamic extremists dominate Syrian opposition

1 Comment

Reuters reports on it with the headline “Kerry portrait of Syria rebels at odds with intelligence reports”.

Excerpt:

Secretary of State John Kerry’s public assertions that moderate Syrian opposition groups are growing in influence appear to be at odds with estimates by U.S. and European intelligence sources and nongovernmental experts, who say Islamic extremists remain by far the fiercest and best-organized rebel elements.

At congressional hearings this week, while making the case for President Barack Obama’s plan for limited military action in Syria, Kerry asserted that the armed opposition to Syrian President Bashar al-Assad “has increasingly become more defined by its moderation, more defined by the breadth of its membership, and more defined by its adherence to some, you know, democratic process and to an all-inclusive, minority-protecting constitution.

“And the opposition is getting stronger by the day,” Kerry told the Senate Foreign Relations Committee on Tuesday.

U.S. and allied intelligence sources and private experts on the Syrian conflict suggest that assessment is optimistic.

While the radical Islamists among the rebels may not be numerically superior to more moderate fighters, they say, Islamist groups like the al Qaeda-aligned Nusra Front are better organized, armed and trained.

Kerry’s remarks represented a change in tone by the Obama administration, which for more than two years has been wary of sending U.S. arms to the rebels, citing fears they could fall into radical Islamists’ hands.

As recently as late July, at a security conference in Aspen, Colorado, the deputy director of the Pentagon’s Defense Intelligence Agency, David Shedd, estimated that there were at least 1,200 different Syrian rebel groups and that Islamic extremists, notably the Nusra Front, were well-placed to expand their influence.

“Left unchecked, I’m very concerned that the most radical elements will take over larger segments” of the opposition groups, Shedd said. He added that the conflict could drag on anywhere “from many, many months to multiple years” and that a prolonged stalemate could leave open parts of Syria to potential control by radical fighters.

U.S. and allied intelligence sources said that such assessments have not changed.

As an aside, the mainstream media has not been reporting on these intelligence reports.

Excerpt:

A new survey of the coverage of the Syrian civil war and the U.S. response to it by the big three networks, ABC, CBS, and NBC, shows that 94 percent of their stories have not mentioned that some of the rebel forces include America’s enemy, al Qaeda.

The survey, reported by the Media Research Center’s Dan Gainor, finds that since August 21, 171 stories about the conflict have aired on the networks. Of those, only 11 stories mentioned the al Qaeda element of the war.

ABC, for instance, has aired 51 stories about the Syrian conflagration but only mentioned al Qaeda in 3 of those reports. NBC was worse: out of its 64 stories, only 3 mentioned the notorious terrorist group. NBC was a little better, mentioning al Qaeda 5 times in its 56 stories.

Al Qaeda is not yet ubiquitous among the rebel forces, but its presence is growing, something the networks should be warning their viewers about.

Now, I was initially in favor of a targeted strike aimed at the leadership of the Syrian regime, assuming two things were cleared up first. 1) We had to be sure that Assad was responsible for the use of the chemical weapons. Despite what the Obama administration says, we are still not sure who used the chemical weapons. 2) We had to be sure that there were moderate elements in the leadership of the Syrian opposition. Well, we now know that this is not the case. So, my position has changed, and now I am in favor of not launching a strike at the leaders of the Assad regime. (Note: this option was not what Obama was suggesting, anyway – his strike was not targeted at the leaders).

I do think that it is important to deter the use of chemical weapons. That is a valid concern, and a strike at leaders who use chemical weapons is a valid way of achieving that goal of saving civilians from future attacks. But we have to be sure that we don’t do more harm, and right now it doesn’t look like that will happen.
