Earthzine is an online source for news, articles, information and educational materials about Earth science, Earth observations and users of Earth information for the international Earth-observing community. Earthzine is updated regularly with news from around the world about the Earth, Earth observations, environmental policy, and new and emerging environmentally-friendly and earth-observing technologies.

"What is the Earth Exploration Toolbook? The Earth Exploration Toolbook is a collection of computer-based Earth science activities. Each activity, or chapter, introduces one or more data sets and an analysis tool that enables users to explore some aspect of the Earth system. Step-by-step instructions in each chapter walk users through an example - a case study in which they access data and use analysis tools to explore issues or concepts in Earth system science. In the course of completing a chapter, users produce and analyze maps, graphs, images, or other data products. The ultimate goal of each activity is to build user's skills and confidence so they can use data to conduct their own investigations of the Earth system."

Some GigaPan images are posted on Google Earth, a Google application that allows for close zooming on any area of the earth. Places where GigaPan images are placed allow for clearer, more detailed images than Google Earth itself would display. The images posted on the GigaPan website and Google Earth of places all around the world have made it easier for geology students to experience a variety of fieldwork

"Global, zoomable time-lapse map... View stunning phenomena such as the sprouting of Dubai's artificial Palm Islands, the retreat of Alaska's Columbia Glacier, the deforestation of the Brazilian Amazon and urban growth in Las Vegas from 1984 to 2012 Using Google Earth Engine technology, we sifted through 2,068,467 images-a total of 909 terabytes of data-to find the highest-quality pixels (e.g., those without clouds), for every year since 1984 and for every spot on Earth. We then compiled these into enormous planetary images, 1.78 terapixels each, one for each year. As the final step, we worked with the CREATE Lab at Carnegie Mellon University, recipients of a Google Focused Research Award, to convert these annual Earth images into a seamless, browsable HTML5 animation. Check it out on Google's Timelapse website."

Compare two images in Google Earth side-by-side using both historical and current imagery.

Earthquakes, tsunamis, floods, wildfires... "IcEarth offers an innovative approach for the use of satellite and airborne remotely sensed data and current and historical aerial photography combined with an in-depth explanation of what the data represents. Images, technical application, and topical themes support environmental science, earth science, and geographic inquiry by complementing educators existing curriculum."

Science.gov now quickly finds science images, including animal and plant, weather and space, and earth and sun images and more. The information is free and no registration is required. Go to www.science.gov and select the Image Search link under Special Collections.

"Last week we made imagery from NASA's MODIS available as an overlay for Google Earth, which currently shows the extent of the oil spill through April 29, and we'll continue to add more imagery as it becomes available. We've also made radar images from ESA's ENVISAT available through this KML file. Below, you can see the progression of the spill over time."

"Google Earth Engine brings together the world's satellite imagery-trillions of scientific measurements dating back more than 25 years-and makes it available online with tools for scientists, independent researchers, and nations to mine this massive warehouse of data to detect changes, map trends and quantify differences to the earth's surface.

"Have you ever wondered what the tree population and density of the United States looks like? This amazing map shows just that. Created by Josef Kellndorfer and Wayne Walker of Woods Hole Research Center in conjunction with the U. S. Geological Survey Science Center's Earth Resources Observation and Science (EROS) Center and the US Forest Service, the map was generated based on a series of data sources including readings collected from space-based radars, satellite sensors, computer models, and simply counting trees the old-fashioned way. The map was created for NASA to help determine how the world's forests have the potential to store more carbon in the future."

"Scientists peer into the next decades of environmental change on Planet Earth." Good news stories include ongoing recovery from effects of acid rain in the Adirondacks + new pathways to a sustainable future developed through modeling, ecological forecasting, and mapping responses to environmental change.

"We often think of rivers as following a given path for the course of its life, but really, the path changes over time as the flow cuts into the earth. The water flows through old and new and back again. In 1944, cartographer Harold Fisk mapped the current Mississippi River. It's the white trail. Then Fisk used old geological maps to display old paths. They're the old colored paths. And what you get is this long run of windy, snake-like things."

"In this activity, undergraduate students use Google Earth to investigate a variety of renewable energy sources and select sites within the United States that would be appropriate for projects based on those sources. These sources include solar energy, bioenergy, hydroelectricity, tidal power, wind energy, wave energy, and geothermal energy."

This interactive investigation explores these questions: - What evolutionary processes have affected the distribution of Earth's species today and in the past? - How do scientists study past evolutionary processes on Earth? - How do graphs and charts help scientists test their hypotheses?

"Explore the signs of global warming on this map or Google Earth. The evidence of climate change includes heat waves, sea-level rise, flooding, melting glaciers, earlier spring arrival, coral reef bleaching, and the spread of disease."
