False Precision: In their early education, many students of science faced the problem of significant numbers (digits). A useful rule of thumb was that the chain was only as strong as its weakest link. In measurement, the less precise instrument making the measurements determines precision of any dataset representing the measurements. A mathematical operation does not add precision to the instruments, or the dataset. For example, as discussed in the January 21 TWTW, the widely used Automatic Surface Observing System (ASOS) instruments at airports have a precision of plus or minus 1 degree C (1.8 F, correctly, 2 F). Surface datasets using these measurements cannot be more precise than these instruments. Yet, routinely, some government agencies report data, after mathematical manipulation, with far greater precision – to one-hundredths of a degree C. Such precision is false.

Writing in the non-conservative Boston Globe, columnist Jeff Jacoby gives a simple illustration on how small errors in measurement can compound in a computer model with many small errors. Any assumption that the errors will cancel each other out needs to be demonstrated. However, in the reports of the UN Intergovernmental Panel on Climate Change (IPCC) and its followers, such cancellation of errors is not demonstrated.

Renewable Energy, What is the Cost?

By Andy May – Re-Blogged From http://www.WattsUpWithThat.com

A key question to think about, do renewable fuels decrease fossil fuel use, or do they increase it?

What are the costs of using renewable energy? The sun and wind are free, does that make wind and solar power free? Biofuels require power to plant crops, make fertilizer and spread it, harvest the plants, make and transport the ethanol. Solar and wind require power to produce, transport and install the equipment. All renewable energy sources require lots of land per megawatt of electricity produced. We will not be able to determine a cost for renewable power in this essay, but we can discuss the components of the calculation and provide some context.

Searching for Honest Energy Policies

By Paul Driessen – Re-Blogged From http://www.WattsUpWithThat.com

Renewable energy is defective solution in search of a problem, money and power.

The Greek philosopher Diogenes reportedly carried an oil lamp during the daytime, the better to help him find an honest man. People everywhere should join Congress and the Trump Administration in search of honest energy and climate policies – as too many existing policies were devised by special interests seeking money and power, and often using imaginary problems to justify their quest.

Global Climate Models: Judith Curry wrote a powerful critique of global climate models, “Climate Models for the Layman”, that was published by the Global Warming Policy Foundation. A few of the key points are discussed below. For those with a deeper interest in climate science or climate modeling, the entire paper is worthwhile.

In the executive summary, Curry presents several fundamental scientific points on Global Climate Models (GMCs) including:

“GCMs have not been subject to the rigorous verification and validation that is the norm for engineering and regulatory science.

There are valid concerns about a fundamental lack of predictability in the complex nonlinear climate system.”

The UN Intergovernmental Panel on Climate Change (IPCC) is well aware of the failure to produce valid models. Five-time Assessment Report (AR) commentator Vincent Gray of New Zealand has repeatedly stated this failure to the IPCC. The IPCC has responded by evasive tactics such as changing terms of predictions to projections and terming highly questionable, evasive procedures as evaluation. Government entities that depend on the IPCC findings follow suit. These include the US Global Change Research Program (USGCRP), including its highly dubious calculations of the “Social Cost of Carbon”, and the EPA in its ambiguous finding that greenhouse gases, especially carbon dioxide, endanger public health and welfare.

Renewables Won’t Work – Even If Climate Claims are True

By Eric Worrall – Re-Blogged From http://www.WattsUpWithThat.com

Imagine for a moment that all the wild claims of climate driven future weather disasters will occur as predicted. In this imaginary future climate dystopia, how will wind power cope with super storms? How will solar power cope with hail, tornadoes, cyclones and floods? How will hydro power cope with endless droughts? How will biofuel crops cope with storm damage, droughts and unseasonal heatwaves?

False Precision – Hottest Year Ever? NASA’s Goddard Institute for Space Studies (NASA-GISS) and NOAA’s National Centers for Environmental Information (NCEI) issued dramatic press releases that 2016 was the hottest year since instrument measurements began. Both organizations focus on surface data, which has far from comprehensive coverage. According to NOAA-NCEI, 2016 was 0.07ºF warmer than 2015.

David Whitehouse, Science Editor for the Global Warming Policy Forum (GWPF), stated that “Peter Stott, Acting Director of the Met Office Hadley Centre, said in no uncertain terms that, ‘a particularly strong El Nino event contributed about 0.2°C [about 0.4 ºF] to the annual average for 2016.’” Thus, based on the comment by Stott, the contribution of the El Niño was about 5 times larger than the reported increase in global temperatures from 2015 to 2016. The tiny, calculated margin is hardly worthy of dramatic press releases.

The tiny, calculated margin does not account for lack of global coverage in surface measurements, questionable adjustments in the data, and limited accuracy of the instrumentation. As presented on page 9 of the 2008 NIPCC report, by 1997 the number of 5º by 5º global grid boxes with both minimum and maximum readings fell to about 100 out of more than 2500 possible.
