NASA uses the vantage point of space to increase our understanding of our home planet, improve lives, and safeguard our future.
We monitor Earthâ€™s vital signs from land, air and space with a fleet of satellites and ambitious airborne and ground-based observation campaigns. NASA develops new ways to observe and study Earth’s interconnected natural systems with long-term data records. The agency freely shares this unique knowledge and works with institutions around the world.
Scientists worldwide use NASA data to tackle some of the biggest questions about how our planet is changing now and how Earth could change in the future. From rising sea levels to the changing availability of freshwater, NASA enables studies that unravel the complexities of our planet from the highest reaches of Earthâ€™s atmosphere to its core.
NASAâ€™s Earth science work also makes a difference in peopleâ€™s lives around the world every day. From farms to our national parks, from todayâ€™s response to natural disasters to tomorrowâ€™s air quality, from the Arctic to the Amazon, NASA is working for you 24/7.
NASAâ€™s expertise in space and scientific exploration contributes to essential services provided to the American people by other federal agencies, such as weather forecasting and natural resource management.
All of this new knowledge about our home planet enables policy makers, government agencies and other stakeholders to make more informed decisions on critical issues that occur all around the world.
NASA keeps track of sea level change and its causes from space. Find out more about how NASA satellite observations help our understanding of this complex topic.
Eradicating global poverty is within reach, but under threat from a changing climate. Left unchecked, climate change will put at risk our ability to lift people out of extreme poverty permanently by 2030, the first target of the Sustainable Development Goals. Coal is the worldâ€™s number one source of CO2 emissions. Most historic emissions came from the coal industry in the developed world in the last century, with China joining the biggest emitters at the beginning of this one. It is widely accepted that a rapid and just response to climate change will require the urgent replacement of coal with low-carbon energy sources in rich economies.
A subject both complex and controversial, climate change is a problem of global proportions. A Web search engine will return well over one million results for a query about â€œglobal climate change.â€ In spite ofâ€”or perhaps because ofâ€”this wealth of information, how people view and interpret climate change concepts varies greatly. Understanding the subject enough to understand the various perspectives on climate change is a significant challenge. However, developing this understanding is key, as climate change may be the most critical challenge facing our world today. Decisions made today will have far-reaching, long-standing effects.
This module provides a multi-faceted context for understanding the issues surrounding climate change. It summarizes some of the readily available basic information, presents multiple perspectives on global climate change research and policy, and provides classroom activities that place climate change issues in a context accessible to students. The distinctive contributions of this module to the current body of instructional resources on global climate change include:
A unique combination of perspectives, skills, and tools to help individuals critically evaluate climate change data and controversy;
An integration of basic scientific concepts with potential solutions involving behavioral and technological change; and
The inclusion of the perspectives of researchers at the Massachusetts Institute of Technology (MIT) and elsewhere working on the frontier of climate change research.
For much of modern history, climate has been predictable enough to have worked its way into the very culture, industry, and infrastructure of our society. It would make little sense to support a ski industry in Colorado if not for the expectation of snow, and it would make little sense to support a vacation industry in Florida if not for the expectation of sun. Expected climate conditions are the basis for the nation’s farming, transportation, and water management practices, among many others. But Earth’s climate system is, in a word, complicated. It incorporates thousands of factors that interact in space and time around the globe and over many generations. For several decades, scientists have used the world’s most advanced computers to both simulate climate and predict future climate. Industries such as those mentioned above increasingly rely on information from these models to guide decision making–and with a changing climate, the information is more important than ever. This site is a primer on how climate models work. The information is based on expert consensus reports from the National Research Council’s Board on Atmospheric Sciences and Climate.
The changing climate impacts society and ecosystems in a broad variety of ways. For example, climate change can alter rainfall, influence crop yields, affect human health, cause changes to forests and other ecosystems, and even impact our energy supply. Climate-related impacts are occurring across the country and over many sectors of our economy.
Explore the impacts of climate change by region, by sector, or by state.
This website is designed to help educators understand climate and weather concepts and to be able to incorporate the learning material from this site into their course curriculum using examples as aids for learning. It is also useful for anyone else who wants a basic understanding of weather and climate, especially in the southeastern United States.
This study advances a detailed social-psychological model of climate change risk perceptions by combining and integrating cognitive, experiential, and socio-cultural factors. The conceptual model is tested empirically on a national sample (N = 808) of the UK population. Results indicate that the full climate change risk perception model (CCRPM) is able to explain nearly 70% of the variance in risk perception. Gender, political party, knowledge of the causes, impacts and responses to climate change, social norms, value orientations, affect and personal experience with extreme weather were all identified as significant predictors. Experiential and socio-cultural factors explained significantly more variance in risk perception than either cognitive or socio-demographic characteristics. Results also confirm that the factor analytic structure of climate change risk perceptions can be conceptualized along two key dimensions, namely: personal and societal risk judgments and that both dimensions have different psychological antecedents. Implications for theory and public risk communication are discussed.
The National Marine Sanctuary Webinar Series provides educators with educational and scientific expertise, resources and training to support ocean and climate literacy in the classroom. This series targets formal and informal educators that are engaging students (elementary through college) in formal classroom settings, as well as members of the community in informal educational venues (e.g. after school programs, science centers, aquariums, etc.).
Objective measurements of storm intensity show that North Atlantic hurricanes have grown more destructive in recent decades. But coastal residents’ views on the matter depend less on scientific fact and more on their gender, belief in climate change and recent experience with hurricanes, according to a new study by researchers at Princeton University, Auburn University-Montgomery, the Louisiana State University and Texas A&M University.
