These are the scientific priorities put forward by the National Academy of Sciences, Engineering and Medical Sciences in a new report released on Friday. However, the priorities for funding are set by the National Assembly. Therefore, it is a pending issue whether these agencies will implement these proposals in the future. The Trump administration has said it will cut funding for the NASA Earth Science Project and reduce funding for geostationary satellites used to track the storm. But Bill Gail, global technology chief technology officer and co-author of the report, said the National Academy report is based on realistic budgets and Congress "has always given these proposals a great deal of respect."

Gail added: "It's not always our job to respond to current politics by changing the government. Our job is to put aside what we consider to be objective, achievable observers, and then let the government go about it."

The report, "Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space," called on three federal agencies to work together to comprehensively reduce the uncertainty of climate change forecasts and improve the forecast of weather and air quality, Landslides, earthquakes and volcanic eruptions and other hazards.

Waleed Abdalati, director of the Colorado Institute for Environmental Science Research Collaboration at the University of Colorado, said in a story: "Whether we realize it or not, the Earth's information from space has become an integral part of our daily lives. Understanding the behavior of the planet is crucial. "

Studying the Earth with satellites is the key to understanding how ecosystems work and how polar ice affects the world's climate. For example, one NASA satellite is mapping carbon dioxide in the atmosphere as a greenhouse gas, helping scientists to understand more about how plants work and how the land and oceans absorb and release carbon dioxide. This is the key if we want to know how much the temperature will rise in the next few decades. The information collected by the satellites is also important for weather forecasting and is also crucial to the mapping services we use daily on smartphones.

The report, which took two years to complete, takes advantage of research proposals from U.S. scientists and engineers to ensure that the scientific events that took place at NASA, the National Oceanic and Atmospheric Administration and the United States Geological Survey are " Demand-driven ". The researchers put forward 35 key questions on geosciences and applications, as well as 24 major goals that the three U.S. agencies should complete within the next ten years.

The report points out that our behavior is the reason that causes our planet to constantly change. Understanding these changes is crucial to the future well-being of humankind living here.
