NOAA’s USCRN Revisited – no significant warming in the USA in 12 years

A typical USCRN station.

By Willis Eschenbach

Back in 2014, Anthony put up a post called “NOAA shows ‘the pause’ in the U.S. surface temperature record over nearly a decade“. In it, he discussed the record of the US Climate Reference Network (USCRN). I can’t better Anthony’s description of the USCRN, so I’m stealing it to use here:

This data is from state-of-the-art ultra-reliable triple redundant weather stations placed on pristine environments. As a result, these temperature data need none of the adjustments that plague the older surface temperature networks, such as USHCN and GHCN, which have been heavily adjusted to attempt corrections for a wide variety of biases. Using NOAA’s own USCRN data, which eliminates all of the squabbles over the accuracy of and the adjustment of temperature data, we can get a clear plot of pristine surface data.

So … what does the USCRN show in 2017? Well, about the same as it showed in 2014 … no statistically significant warming since the start of the record. Here’s the graph from their website.

Trend = 0.6 ± 0.9 °C/decade, p-value = 0.31, far from significant. Source: NCDC National Temperature Index time series plotter

So … still no significant trend. Yes, the dataset is short, 13 years … but there are a number of 13-year periods in US temperature history which do have significant trends.

Finally, do you remember January 2006, when the entire US averaged four degrees C above average, twice the scare-factor temperature rise of two degrees C?

Well, me neither. Many people, including scientists who should know better, hyperventilate about a tenth of a degree C, but we hardly remember four degrees C …

Ah, well. Here on the north coast of California it’s raining, which is always a wondrous thing. The leaves on all of the plants are getting a brisk washing, the trees are shrouded in a luminous mist. The only dissenter is the cat …

A call for an improved global climate measurement system

From the UNIVERSITY OF COLORADO AT BOULDER and the “weather stations near heat sources aren’t measuring climate” department, something that we already have in the USA in the form of the state-of-the-art Climate Reference Network, CRN, but we don’t have globally. This call for a better system is something I agree with, because much of the existing monitoring network has problems like you see in the photo below, among other problems.

Improving climate observations offers major return on investment

A well-designed climate observing system could deliver trillions of dollars in economic benefits.

A well-designed climate observing system could help scientists answer knotty questions about climate while delivering trillions of dollars in benefits by providing decision makers information they need to protect public health and the economy in the coming decades, according to a new paper published today.

The flip side is also true, said lead author Elizabeth Weatherhead, a scientist with CIRES at the University of Colorado Boulder. The cost of failing to invest in improving our ability to predict and plan for droughts, floods, extreme heat events, famine, sea level rise and changes in freshwater availability could reach hundreds of billions of dollars each year, she and her colleagues wrote. Their paper is published in the current edition of Earth’s Future, an online journal of the American Geophysical Union.

“Improving our understanding of climate not only offers large societal benefits but also significant economic returns,” Weatherhead said. “We’re not specifying which measurement (or observing) systems to target, we’re simply saying it’s a smart investment to address the most pressing societal needs.”

Data generated by the current assemblage of observing systems, including NOAA’s satellite and ground-based observing systems, have yielded significant insights into important climate questions. However, coordinated development and expansion of climate observing systems are required to advance weather and climate prediction to address the scale of risks likely in the future.

For instance, the current observing system cannot monitor precipitation extremes throughout much of the world, and cannot forecast the likelihood of extreme flooding well enough to sufficiently guide rebuilding efforts. “The current decline of our Earth observing systems is likely to continue into the foreseeable future,” said Liz Moyer, a climate researcher at the University of Chicago who was not involved in the new assessment. “Unless action is taken–such as suggested in this paper–our ability to plan for and respond to some of the most important aspects of climate, including extreme events and water availability, will be significantly limited.”

Weatherhead and a team that included four NOAA laboratory directors and many other prominent climate scientists urge that investments focus on tackling seven “grand challenges,” such as predicting extreme weather and climate shifts, the role of clouds and circulation in regulating climate, the regional sea level change and coastal impacts, understanding the consequences melting ice, and feedback loops involving carbon cycling. In each category, observations are needed to inform process studies, to build long-term datasets against which to evaluate changing conditions,and ultimately to improve modeling and forecasting capabilities.

“We are on the threshold of a new era in prediction, drawing on our knowledge of the entire Earth system to strengthen societal resilience to potential climate and weather disasters,” said co-author Antonio Busalacchi, president of the University Corporation for Atmospheric Research. “Strategic investments in observing technologies will pay for themselves many times over by protecting life and property, promoting economic growth, and providing needed intelligence to decision makers.”

“Well planned observations are important to more than just understanding climate,” agreed Deon Terblanche, director of research at the World Meteorological Organization. “Predicting the weather and extreme events, and managing water availability and energy demand will all benefit,”

“Developing observation systems focused on the major scientific questions with a rigorous evaluation process to ensure the measurement quality is fit-for-purpose–as the authors propose–will more than pay off in the long run,” said Tom Gardiner, a principal research scientist at the UK’s National Physical Laboratory.

Objective evaluations of proposed observing systems, including satellites, ground-based or in-situ observations as well as new, currently unidentified observational approaches, will be needed to prioritize investments and maximize societal benefits, the authors propose.

“We need to take a critical look at what’s needed to address the most important climate questions,” said NASA scientist and co-author Bruce Wielicki.

Not all new observing strategies would necessarily require expensive new systems like satellites, the authors pointed out. For example, after a devastating flood hit Fort Collins, Colo. in 1998, the state climatologist developed a network of trained volunteers to supplement official National Weather Service precipitation measurements using low-cost measuring tools and a dedicated web portal. The Community Collaborative Rain, Hail and Snow now counts thousands of volunteers nationwide who provide the data directly to the National Weather Service.

Using a rigorous evaluation process to develop a robust network of observation systems focused on the major scientific questions will more than pay off in the long run, the authors concluded.

“The economic risks from climate change are measured in trillions of dollars,” agreed Rich Sorkin, CEO of Jupiter, a Silicon Valley-based company that provides intelligence on weather and climate risks around the globe. “So an improved, properly designed observing system, with commensurate investments in science and understanding, has the potential to be of tremendous value to society.”

Designing the Climate Observing System of the Future

Weatherhead, et al., 2017

Abstract

Climate observations are needed to address a large range of important societal issues including sea level rise, droughts, floods, extreme heat events, food security, and fresh water availability in the coming decades. Past, targeted investments in specific climate questions have resulted in tremendous improvements in issues important to human health, security, and infrastructure. However, the current climate observing system was not planned in a comprehensive, focused manner required to adequately address the full range of climate needs. A potential approach to planning the observing system of the future is presented in this paper. First, this paper proposes that priority be given to the most critical needs as identified within the World Climate Research Program as Grand Challenges. These currently include seven important topics: Melting Ice and Global Consequences; Clouds, Circulation and Climate Sensitivity; Carbon Feedbacks in the Climate System; Understanding and Predicting Weather and Climate Extremes; Water for the Food Baskets of the World; Regional Sea-Level Change and Coastal Impacts; and Near-term Climate Prediction. For each Grand Challenge, observations are needed for long-term monitoring, process studies and forecasting capabilities. Second, objective evaluations of proposed observing systems, including satellites, ground-based and in situ observations as well as potentially new, unidentified observational approaches, can quantify the ability to address these climate priorities. And third, investments in effective climate observations will be economically important as they will offer a magnified return on investment that justifies a far greater development of observations to serve society’s needs.
