The Real Climate Terror

The Obama Administration is sticking to its talking points claiming climate change affects us more than terrorism. It might be valuable to compare and contrast the real life affects Americans endure from both of these threats.

First, let’s take a look at climate change’s effects in the United States: Hurricane power, when measured by satellites, is near its lowest ever ebb. There’s no change in the frequency of severe tornados. The relationship between heavy snow and temperature is negative along the East Coast. Carbon dioxide and longer growing seasons are significantly increasing the world’s food supply, and there’s no relationship between global temperature and U.S. drought.

Compare this with the effects of terrorism: On September 11, 2011, terrorists took down the World Trade Center and nearly an entire side of the Pentagon, extinguishing 2,996 lives. As a result, every American’s privacy is assaulted by the government on a daily basis—and let’s not talk about what they’ve done to air travel, or worse, Iraq. We’ve managed to remain in a perpetual state of war, unleashing a wave of federal spending our great grandchildren will be repaying.

Perhaps next time President Obama skips the TSA lines to fly around the world on Air Force One (on the taxpayer dime, emitting the carbon of which he’s so scared) he should look down at Arlington National Cemetery at the tombstones left from the reaction to terrorism–it’s an excellent reminder of the real cost of government action.

Spinning Global Sea Ice

NASA takes the (frozen) cake with this one.

It just released a report on global sea ice coverage that opens with the following sentence:

Sea ice increases in Antarctica do not make up for the accelerated Arctic sea ice loss of the last decades, a new NASA study finds.

NASA continued:

Furthermore, the global ice decrease has accelerated: in the first half of the record (1979-96), the sea ice loss was about 8,300 square miles (21,500 square kilometers) per year. This rate more than doubled for the second half of the period (1996 to 2013), when there was an average loss of 19,500 square miles (50,500 square kilometers) per year – an average yearly loss larger than the states of Vermont and New Hampshire combined.

Could have fooled us!

Figure 1 shows the sea ice coverage (anomalies) measured by satellite, as reported today by the University of Illinois at Urbana-Champaign’s website Cryosphere Today for the period since 1979 for the Arctic (left panel) and Antarctic (right panel). There has been an overall decline in Northern Hemisphere sea ice and a contemporaneous increase in Southern Hemisphere sea ice. It is also worth noting that the decline in Northern Hemisphere ice stopped about eight years ago, even as the within-year variability has gotten larger (perhaps because of thinning at the margins).

Put them together and what do you get?  See Figure 2—the global sea ice history from 1979 through early 2015. The blow-up shows the last 10 years.

 

Figure 2. Global sea ice area anomalies (red line, million square kilometers) from 1979 to present. The insert shows the data since 2006 (image source: Cryosphere Today).

With the data available to us (and what NASA used, too), let’s check the veracity of NASA’s claims.

Is it true that increases around Antarctica don’t compensate for Arctic decreases? Nope.

The global ice anomaly (Figure 2) for the past two years has remained very close to the 30-yr (1979-2008) average.  This has happened because the increases around Antarctica have completely made up for the losses in the Arctic.

Is the loss of global sea-ice accelerating? Again, nope.

Look at the inset in Figure 2. It represents the second half of the period that NASA has offered to support its acceleration conclusion. Since 2006 (the past 9 years), global sea ice has increased.

How on earth can an extended period of increase be used as support for an accelerating decrease?!

No, Global Warming Doesn’t Lead to More Snow in Boston

Global Science Report is a feature from the Center for the Study of Science, where we highlight one or two important new items in the scientific literature or the popular media. For broader and more technical perspectives, consult our monthly “Current Wisdom.”

As the snow keeps piling up in Boston, so does the climate change nonsense. Never letting a good weather story go to waste, our nation’s scribes are in high dudgeon that global warming is causing the serial burial of Boston.

We discussed the illogic (or at least the selective reasoning) behind the global-warming-made-this-snowstorm-worse excuses forwarded during the first big nor’easter to wallop the area (back on January 27th), and now, after the third big event (with likely more to come!) the din is deafening. Just today there are major stories in USA Today and the Washington Post strongly suggesting that global warming enhances snowfall in New England.

Perhaps we can test this hypothesis, glibly hiding as a fact.

Back in the late 1990s, we were involved in a research project investigating the relationship between winter temperature and winter snowfall across Canada. Our results were published in the peer-reviewed Journal Geophysical Research back in 1999.  We weren’t investigating the meteorology of any one specific storm, but rather the climatology (i.e., the general relationship) of temperature and snowfall, looking to see if there were really places that were “too cold to snow” and whether a warming climate might result in more snowfall, or precisely what is being presented as fact today.

Admitting FutureGen’s Failure

The Department of Energy (DOE) is admitting that it failed. Last week, it announced that it will stop development of FutureGen 2.0, a federally-financed, coal-fired power plant in Illinois. FutureGen, and its successor FutureGen 2.0, wasted millions of tax dollars, and was beset with multiple delays and cost overruns.

FutureGen was one of many federal energy projects experimenting in so-called “clean coal” technology. FutureGen sought to demonstrate the technical capabilities of carbon capture and sequestration (CCS) technology. CCS attempts to capture carbon dioxide emissions from coal-fired power plants and store it underground, eliminating an increase in atmospheric carbon dioxide.

FutureGen was launched in 2003 by the George W. Bush administration as a public-private partnership to demonstrate CCS with a site chosen in Illinois. Costs would be shared among the federal government and 12 private energy companies. The project’s estimated cost grew from $1 billion to $1.8 billion by 2008, when it was cancelled due to the cost overruns.  

In 2010 the Obama administration revived the project using stimulus funding. The new project, FutureGen 2.0, was allotted $1 billion from the federal government, with private investors supposed to be providing additional funding.

The Great Temperature Adjustment Flap

Matt Drudge has been riveting eyeballs by highlighting a London Telegraph piece calling the “fiddling” of raw temperature histories “the biggest science scandal ever.” The fact of the matter is some of the adjustments that have been tacked onto some temperature records are pretty alarming—but what do they really mean?

One of the more egregious ones has been the adjustment of the long-running record from Central Park (NYC). Basically it’s been flat for over a hundred years but the National Climatic Data Center, which generates its own global temperature history, has stuck a warming trend of several degrees in it during the last quarter-century, simply because it doesn’t agree with some other stations (which also don’t happen to be in the stable urban core of Manhattan).

Internationally, Cato Scholar Ross McKitrick and yours truly documented a propensity for many African and South American stations to report warming that really isn’t happening.  Some of those records, notably in Paraguay and central South America, have been massively altered.

At any rate, Chris Booker, author of the Telegraph article, isn’t the first person to be alarmed at what has been done to some of the temperature records.  Others, such as Richard Muller, from UC-Berkeley, along with Steven Mosher, were so concerned that they literally re-invented the surface temperature history from scratch. In doing so, both of them found the “adjustments” really don’t make all that much difference when compared the larger universe of data. While this result has been documented  by the scientific organization Berkeley Earth, it has yet to appear in one of the big climate journals, a sign that it might be having a rough time in the review process.

You Ought to Have a Look: Tamping Down Expectations for Paris

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.

Some folks are just slow to get it.

There is no way on God’s greening earth that international negotiators are going to achieve the emissions reductions that climate models tell them are necessary to keep the rise in the planet’s average surface temperature to less than 2°C above the pre-industrial value.

At the United Nations climate meeting held in Cancun back in 2012, after kicking around the idea for several years, negotiators foolishly adopted 2°C as the level associated with a “dangerous interference” with the climate system—what everyone agreed to try to avoid way back in 1992 under the Rio Treaty.

Bad idea—it won’t happen. Even the folks at the U.N. are starting to realize it.

According to an article in this week’s The Guardian titled “Paris Climate Summit: Missing Global Warming Target ‘Would Not Be Aailure’”:

EU climate chief and UN’s top climate official both play down expectations that international climate talk pledges will help hit 2C target… “2C is an objective,” Miguel Arias Canete, the EU climate chief, said. “If we have an ongoing process you can not say it is a failure if the mitigation commitments do not reach 2C.”

…In Brussels, meanwhile, the UN top climate official, Christiana Figueres, was similarly downplaying expectations, telling reporters the pledges made in the run-up to the Paris meeting later this year will “not get us onto the 2°C pathway”.

There’s so much backpeddling and spinning going on, that you’re motion sick reading the article. While we certainly did see this coming, we didn’t expect the admissions were going to start at this early date.

Current Wisdom: A Closer Look at Climate Model Performance

The Current Wisdom is a series of monthly articles in which Patrick J. Michaels and Paul C. “Chip” Knappenberger, from Cato’s Center for the Study of Science, review interesting items on global warming in the scientific literature or of a more technical nature. These items may not have received the media attention that they deserved or have been misinterpreted in the popular press.

Posted Wednesday in the Washington Post’s new online “Energy and Environment” section is a piece titled “No, Climate Models Aren’t Exaggerating Global Warming.” That’s a pretty “out there” headline considering all the evidence to the contrary.

We summed up much of the contrary evidence in a presentation at the annual meeting of the American Geophysical Union last December.  The take-home message—that climate models were on the verge of failure (basically the opposite of the Post headline)—is self-evident in Figure 1, adapted from our presentation.

Figure 1. Comparison of observed trends (colored circles according to legend) with the climate model trends (black circles) for periods from 10 to 64 years in length. All trends end with data from the year 2014 (adapted from Michaels and Knappenberger, 2014).

The figure shows (with colored circles) the value of the trend in observed global average surface temperatures in lengths ranging from 10 to 64 years and in all cases ending in 2014 (the so-called “warmest year on record”). Also included in the figure (black circles) is the average trend in surface temperatures produced by a collection of climate models for the same intervals. For example, for the period 1951–2014 (the leftmost points in the chart, representing a trend length of 64 years) the trend in the observations is 0.11°C per decade and the average model projected trend is 0.15°C per decade. During the most recent 10-year period (2005–2014, rightmost points in the chart), the observed trend is 0.01°C per decade while the model trend is 0.21°C per decade.
