Pope Fallible on Climate Change

Most people think pretty highly of Pope Francis, and I am one of them.  His concern for the poor is exemplary.  His tilt towards gay issues has been widely lauded.  But I am afraid he has been very poorly informed on climate change.

That would be of little consequence, except he is taking the issue very seriously.  Flying to the Philippines on Wednesday, he told reporters  that he will be releasing an encyclical on ecology this coming summer.  According to the AP,

He said he wanted it out in plenty of time to be read and absorbed before the next round of climate change negotiations in Paris in November after the last round in Lima, Peru, failed to reach an agreement.

While he’s definitely right about what happened in Lima, he also is clearly trying to influence the UN process. I guess that’s well and good, after all, the Vatican is a state.  But what is troubling, very troubling, is that poorly informed views on global warming can lead to a tremendously expensive agreement that will do nothing about the climate, while taking away needed resources and exacerbating poverty around the world.

Saturday, in the Philippines, he met with survivors from 2013’s Typhoon Haiyan (also known as Yolanda in the Islands), certainly one of the most powerful storms in recent history. Haiyan reportedly killed 6,000. On the aircraft, Francis said that human activity, meaning emissions of greenhouse gases, was involved. 

A Pope who wants to be as influential as Francis lends great credence to the belief that tropical cyclones (like Haiyan) are being made worse by global warming. These storms are as iconic as polar bears (whose populations are growing) when it comes to generating the political will for a new treaty in Paris. 

It is very easy to see whether global warming is strengthening tropical cyclones.  Dr. Ryan Maue, of Weatherbell Analytics, has examined every storm back to the beginning of global satellite coverage,  for their winds and their duration, which together yield the energy associated with them.  Here’s his result, updated through December 2014:

 

Figure 1. Accumulated Tropical Cyclone Energy, 1972-2014, by Dr. Ryan Maue.  There is simply no relationship between storm activity and global temperature.

The  only way major emissions reductions—of the kind ultimately envisioned by Pope Frances—can be accomplished is to make carbon dioxide-emitting energy so expensive that people will use less, much less.  There’s really no viable energy-dense alternative out there that doesn’t emit CO2. Nuclear fission, which would qualify, is anathema to the same people who want big emissions cuts. His policies will therefore keep the underdeveloped world poor, precisely what he wants to change.

Wealthy societies are much less affected by bad weather than poorer ones. Very strong typhoons regularly strike affluent Hong Kong, with few, if any fatalities.  By making energy unaffordable, the policies Francis wants will impede economic development, so that, decades from now, when a repeat of Haiyan barrels through the Islands, many more will die.

You Ought to Have a Look: Record Global Temperatures

You Ought to Have a Look is a feature from the Center for the Study of Science posted by Patrick J. Michaels and Paul C. (“Chip”) Knappenberger. While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic. Here we post a few of the best in recent days, along with our color commentary.

A lot of buzz around the web was generated late this week with the announcement from the U.S. National Oceanic and Atmospheric Administration that 2014 topped their list as the warmest year since their records began in the late 1800s.

While most of the mainstream media coverage focused on the record-setting temperatures and breathlessly spoke of how this was further indication that humans are warming the climate, the blogosphere was full of articles throwing cold water on this overheated rhetoric by pointing out that despite the past year’s warm temperatures, 1) global warming continues to occur at only a snail’s pace, and 2) this pace is far beneath that projected by the world’s collection of climate models—models developed for the specific purpose of projecting  future climate changes. With each passing year, their performance becomes worse and worse. That is the big story about 2014’s temperatures.

Here are some sites that astutely picked up on that:

Over at Climate Etc., Judy Curry has her say in “‘Warmest year’, ‘pause’, and all that.” Her bottom line?

Berkeley Earth sums it up well with this statement:

That is, of course, an indication that the Earth’s average temperature for the last decade has changed very little.

The key issue remains the growing discrepancy between the climate model projections and the observations: 2014 just made the discrepancy larger.

Speculation about ‘warmest year’ and end of ‘pause’ implies a near term prediction of surface temperatures—that they will be warmer. I’ve made my projection—global surface temperatures will remain mostly flat for at least another decade. However, I’m not willing to place much $$ on that bet, since I suspect that Mother Nature will manage to surprise us. (I will be particularly surprised if the rate of warming in the next decade is at the levels expected by the IPCC.)

Big Brother Wants to Watch You Drive

In 2008, the Washington legislature passed a law mandating a 50 percent reduction in per capita driving by 2050. California and Oregon laws or regulations have similar but somewhat less draconian targets.

The Obama administration wants to mandate that all new cars come equipped with vehicle-to-infrastructure communications, so the car can send signals to and receive messages from street lights and other infrastructure.

Now the California Air Resources Board is considering regulations requiring that all cars monitor their owners’ driving habits, including but not limited to how many miles they drive, how much fuel they use, and how much pollution or greenhouse gases they emit.

Put these all together and you have a system in which the government will not only know where your vehicle is at all times, but can turn off your vehicle if it decides you are driving too much or driving in a way that emits too many grams of carbon dioxide or is otherwise offensive to some bureaucratic imperative.

I sometimes think privacy advocates are a paranoid bunch, seeing men in black around every corner and surveillance helicopters or drones in the air at all times. On the other hand, if a technology is available–such as the ability to record cell phone calls–the government has proven it will use it.

Consider all of the lovable progressives out there who think the government should “punish climate change liars,” meaning people who have differing opinions on scientific issues. It’s not much a stretch to think that, any time they happen to be in power, they will use the available technology to make people stop driving. After all, just how important can that extra trip to the supermarket be compared to the absolute imperative of preventing the seas from rising a quadrillionth of an inch?

Of course, the elected officials and bureaucrats who run this system will exempt themselves from the rules. After all, nothing is more important than their work of running the country and making sure people don’t abuse their freedom by engaging in too much mobility.

As California writer Steven Greenhut points out, we already have red-light cameras, and some “eastern states have suspended drivers from using toll lanes after their transponders showed them to be speeders.” They’re not invading our privacy, the greens will argue, they are just making sure that our actions aren’t harming Mother Earth.

Of course, for many it really isn’t about greenhouse gas emissions. Mobility allows (or, as anti-auto groups would say, forces) people to living in low-density “sprawl” where they can escape taxation by cities eager to subsidize stadiums, convention centers, and light-rail lines. All they have to do is ramp down people’s monthly driving rations–something like a cap-and-trade system that steadily reduces the caps–and suburbanites will eventually find that they have to move back to the cities.

No doubt some will argue that even those who drive the most fuel-efficient cars should be subject to the same driving limits because suburban homes waste energy too. Or that people will be safer from terrorists if they are all jammed together in cities close to emergency facilities than if they are spread across the countryside. Or that suburbanites are parasites on the cities and should be reassimilated back into the cities’ benign embrace and taxing districts.

Whatever the argument, the point is that if the technology is there, the government will use it. If people really want to buy cars that monitor their every move and are capable of communicating those moves to some central infrastructure, they should be allowed to do so. But allowing the government to mandate these things is simply asking to have well-meaning, and sometimes not-so-well-meaning, government bureaucrats control how we travel and where we live.

Kerry, Obama Pressuring India on Climate Change

Secretary of State John Kerry is currently in India as advance guard for President Obama’s visit later this month. The president is going there to try and get some commitment from India (or the illusion of a commitment) to reduce its emissions of dreaded greenhouse gases. Until now, India, along with China, has resisted calls for major reductions, effectively blocking any global treaty limiting fossil fuel use. The president is very keen on changing this before this December’s United Nations confab in Paris, where such a treaty is supposed to be inked. 

Kerry’s mission is to get India ready for the president. Speaking at a trade conference in the state of Gujarat, Kerry said, “Global climate change is already violently affecting communities, not just across India but around the world. It is disrupting commerce, development and economic growth. It’s costing farmers crops.”

In reality, global climate change is exerting no detectable effect on India’s main crop production. 

As shown below the jump, the rate of increase in wheat yields has been constant since records began in the mid-1950s, and the rate of increase in rice yields is actually higher in the last three decades than it was at the start of the record.

Further, if Kerry was saying that climate change is reducing crop yields around the world, that’s wrong too. The increase in global yields has also been constant for decades.

Response to Heat Stress in the United States: Are More Dying or Are More Adapting?

One of the concerns expressed by the United Nations Intergovernmental Panel on Climate Change (IPCC) with respect to the potential impacts of CO2-induced global warming is an increase in the number of heat related deaths, which they predict should occur in response to enhanced summertime temperature variability and more extreme heat waves, particularly among the elderly.

Is this really the case? A new paper published by Bobb et al. (2014) in the scientific journal Environmental Health Perspectives provides an answer. 

In prefacing their work the team of four U.S. researchers writes “increasing temperatures are anticipated to have profound health impacts,” but they say “little is known about the extent to which the population may be adapting.” Therefore, they decided to examine “the hypothesis that if adaptation is occurring, then heat-related mortality would be deceasing over time.”

To accomplish this objective, Bobb et al. used “a national database of daily weather, air pollution, and age-stratified mortality rates for 105 U.S. cities (covering 106 million people) during the summers of 1987-2005,” employing “time-varying coefficient regression models and Bayesian hierarchical models” to estimate “city-specific, regional, and national temporal trends in heat-related mortality and to identify factors that might explain variation across cities.”

With respect to their findings, Bobb et al. state “on average across cities, the number of deaths (per 1,000 deaths) attributable to each 10°F increase in same-day temperature decreased from 51 in 1987 to 19 in 2005” (see Figure 1). Furthermore, they report “this decline was largest among those ≥ 75 years of age, in northern regions, and in cities with cooler climates.”  In addition, they write “although central air conditioning (AC) prevalence has increased, we did not find statistically significant evidence of larger temporal declines among cities with larger increases in AC prevalence.”

Based on these findings, Bobb et al. conclude the U.S. population has, “become more resilient to heat over time”—in this case from 1987 to 2005—led by the country’s astute senior citizens. This discovery, coupled with many other similar findings from all across the world (Idso et al., 2014), adds yet another nail in the coffin of failed IPCC projections of increased heat related mortality in response to the so-called unprecedented warming of the past few decades. Perhaps it is high time for all the other apocalyptic projections of the global warming movement to be removed from life support, as they are each equally failing in comparisons with real world data.

Global Warming and World Food Security

In a recent study to come out of China, Liu et al. (2014) write “food security under the changing climate is a great challenge for the world,” noting it has been stated by Porter et al. (2014) in the IPCC’s Fifth Assessment Report that “the negative impact of global climate warming on crop yield is more common than the positive impact according to the data from the past fifty years.”

That’s not true. Crop yields continue to rise, to the consternation of many, at the exact same rate that they have been rising at since the end of World War II. Even more telling, Liu et al. report studies based on historical data for the past several centuries suggest just the opposite, i.e. that “climate warming is good for crop harvests while climate cooling is bad for crop harvests in the world’s main crop production areas such as Europe (Braudel, 1992; Parker and Smith, 1997; Holopainen and Helama, 2009; Zhang et al., 2011) and China (Zhang, 1996; Ge, 2010; Su et al., 2014) in the temperate region.” They conclude “the current lengths of studies used to evaluate climate impacts on agriculture are too short to detect long-term trends.”

In making their case, the five Chinese scientists employed proxy data-based climate reconstructions that indicate that the Sui dynasty (581-618 AD) and Tang dynasty (618-907 AD) had warm climates comparable with the present, citing in this regard the study of Ge et al. (2003) that shows a strong periodicity in China temperatures. They additionally note that within this primarily warm climate regime, there were imbedded temperature variations—with cooling segments of inter-annual, multiple-decade and century-scale magnitude—which enabled them to assess crop yield responses to both heating and cooling from information provided about food availability in numerous historical documents that have been brought together in several historical compilations that deal with various aspects of China’s past, including Wang (1955), Wei et al. (1973), Li (1974), Liu (1975), Ouyang et al. (1975), Sima (1975), Dong (1985), Wang et al. (1985) and Song (2008). What did they thereby discover?

COP-Out: Political Storyboarding in Peru

The 20th annual “Conference of the Parties” to the UN’s 1992 climate treaty (“COP-20”) is in its second week in Lima, Peru and the news is the same as from pretty much every other one.

You don’t need a calendar to know when these are coming up, as the media are flooded with global warming horror stories every November. This year’s version is that West Antarctic glaciers are shedding a “Mount Everest” of ice every year. That really does raise sea level—about 2/100 of an inch per year. As we noted here, that reality probably wouldn’t have made a headline anywhere.

The meetings are also preceded by some great climate policy “breakthrough.” This year’s was the president’s announcement that China, for the first time, was committed to capping its emissions by 2030. They did no such thing; they said they “intend” to level their emissions off “around” 2030. People “intend” to do a lot of things that don’t happen.

During the first week of these two-day meetings, developing nations coalesce around the notion the developed world (read: United States) must pay them $100 billion per year in perpetuity in order for them to even think about capping their emissions. It’s happened in at least the last five COPs.

In the second week, the UN announces, dolefully, that the conference is deadlocked, usually because the developing world has chosen not to commit economic suicide. Just yesterday, India announced that it simply wasn’t going to reduce its emissions at the expense of development.

Then an American savior descends. In Bali, in 2007, it was Al Gore. In 2009, Barack Obama arrived and barged into one of the developing nation caucuses, only to be asked politely to leave. This week it will be Secretary of State John Kerry, who earned his pre-meeting bones by announcing that climate change is the greatest threat in the world.

I guess nuclear war isn’t so bad after all.

As the deadlock will continue, the UN will announce that the meeting is going to go overtime, beyond its scheduled Friday end. Sometime on the weekend—and usually just in time to get to the Sunday morning newsy shows—Secretary Kerry will announce a breakthrough, the meeting will adjourn, and everyone will go home to begin the cycle anew until next December’s COP-21 in Paris, where a historic agreement will be inked.

Actually, there was something a little different in Lima this year: Given all the travel and its relative distance from Eurasia, COP-20 set the all-time record for carbon dioxide emissions associated with these annual gabfests.
