Can Scientists Learn to Make Daily ‘Nature Forecasts’?
By Michael Dietze
Imagine that spring has finally arrived and you're planning your weekend. The weather forecast looks great. You could go to the beach—but what if it's closed because of an algal bloom? Maybe you could go for a hike—will the leaves be out yet? What might be in flower? Will the migratory birds be back? Oh, and you heard last year was bad for ticks—will this spring be better or worse?
We all take weather forecasts for granted, so why isn't there a "nature forecast" to answer these questions? Enter the new scientific field of ecological forecasting. Ecologists have long sought to understand the natural world, but only recently have they begun to think systematically about forecasting.
Much of the current research in ecological forecasting is focused on long-term projections. It considers questions that play out over decades to centuries, such as how species may shift their ranges in response to climate change, or whether forests will continue to take up carbon dioxide from the atmosphere.
However, in a new article that I co-authored with 18 other scientists from universities, private research institutes and the U.S. Geological Survey, we argue that focusing on near-term forecasts over spans of days, seasons and years will help us better understand, manage and conserve ecosystems. Developing this ability would be a win-win for both science and society.

The Benefits of Forecasting
Beyond helping people plan their weekends, ecological forecasts will improve decision-making in agriculture, forestry, fisheries and other industries. They will help private landowners, local governments and state and federal agencies better manage and conserve our land, water and coastlines, for example by warning of events such as pest outbreaks and harmful algal blooms. They will improve public health through better forecasts of infectious disease outbreaks and better planning in anticipation of famine, wildfires and other natural disasters.
Ecological forecasts will also deepen our understanding of the world around us, and of how human activities are altering it. Forecasting formalizes the cycle between prediction and testing that is at the heart of the scientific method, and repeats it on a much quicker cycle. It can accelerate the pace of discovery in the environmental sciences at this critical time of rapid environmental change.
Weather forecast skill at the National Oceanic and Atmospheric Administration has improved continually and dramatically since the dawn of numerical weather prediction in the 1950s (100 = perfect score, 0 = random), due to more data, faster computers and better modeling tools.
New Tools and Technology
Big data is driving many of the advances in ecological forecasting. Today ecologists have orders of magnitude more data compared to just a decade ago, thanks to sustained public funding for basic science and environmental monitoring. This investment has given us better sensors, satellites and organizations such as the National Ecological Observatory Network, which collects high-quality data from 81 field sites across the U.S. and Puerto Rico. At the same time, cultural shifts across funding agencies, research networks and journals have made that data more open and available.
Digital technologies make it possible to access this information more quickly than in the past. Field notebooks have given way to tablets and cell networks that can stream new data into supercomputers in real time. Computing advances allow us to build better models and use more sophisticated statistical methods to produce forecasts.
Technical and Social Challenges
So far, though, ecological forecasting has not kept pace with advances in data and technology. In our article, we lay out a road map for accelerating the field by tackling the bottlenecks slowing us down.
Some of these bottlenecks are technical, such as better integrating the streams of data that are now available from many different sources, such as field studies, sensor networks and satellite observations.
Other challenges involve human choices. Ecologists need to spend more time engaged in two-way communication with stakeholders, rather than just pushing out the latest research to decision-makers. And we need better ways to transfer state-of-the-art research from universities to agencies and private industry.
Perhaps most limiting is that ecologists traditionally have not been taught forecasting concepts and methods. But as I have written, this situation is changing. There now are summer workshops and a growing number of university courses in ecological forecasting. Prediction is leading to new theories that aim to unify different parts of ecology.
At the dawn of numerical weather prediction in the 1950s, scientists at the National Weather Service faced a choice. They could either wait to start forecasting until the underlying research, models and tools improved, or proceed immediately with making forecasts and learn by doing. They chose the second path. It proved harder than expected—but had they waited, they likely would have failed because they would have missed a critical window when experts and agencies were willing to make major investments in this effort.
Up to now, ecologists have generally adhered to the first, more conservative path. But in this time of rapid environmental change, the societal need and technological capacity for forecasting have never been greater. The forecasts won't always be right, especially as the field develops, but failure is part of learning. The time for ecologists to start forecasting is now.

The Office of Disease Prevention and Health Promotion and the World Health Organization currently recommend either 150 minutes of moderate intensity exercise (walking, gardening, doing household chores) or 75 minutes of vigorous aerobic exercise (running, cycling, swimming) every week.
But there's little research looking at the benefits, if any, of exercising less than the 75 minute minimum.
It seems the reality of the climate crisis is too much for the Federal Reserve to ignore anymore.
For 21 years, Doug Distaso served his country in the United States Air Force.
He commanded joint aviation, maintenance, and support personnel globally and served as a primary legislative affairs lead for two U.S. Special Operations Command leaders.
But after an Air Force plane accident left him with a traumatic brain injury, post-traumatic stress disorder (PTSD), and chronic pain, Distaso was placed on more than a dozen prescription medications by doctors at the U.S. Department of Veterans Affairs (VA).

If you had to choose a diamond for your engagement ring from below or above the ground, which would you pick … and why would you pick it? This is the main question consumers are facing when picking out their diamond engagement ring today. With a dramatic increase in demand for conflict-free lab-grown diamonds, the diamond industry is shifting right before our eyes.
The scourge of plastic waste that washes up on once-pristine beaches and finds its way into the middle of the ocean often starts on land, is dumped in rivers and canals, and gets carried out to sea. At the current rate, marine plastic is predicted to outweigh all the fish in the seas by 2050, according to Silicon Canals.
