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."

"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."

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

"You can use Google Earth to simply search for a place or try one our advanced features, such as recording a tour or importing GPS data. Whether you're learning to use Google Earth for the first time or you're already an expert user, here are some tools to help you explore further. "

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

"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. "

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."

journalist Fred Pearce reports on how the rapid spread of community-based, digital mapping is helping indigenous groups worldwide to claim ownership of their lands and protect them from logging and other outside development. From the Congo, to Guyana, to the Australian outback, local communities are increasingly using GPS technology and Google Earth to document their traditional forests, hunting areas, burial grounds, and important cultural sites. As Pearce writes, the aim is to produce maps that governments cannot ignore and that can assist local people in saving their homelands

"Berkeley Earth has just released analysis of land-surface temperature records going back 250 years, about 100 years further than previous studies. The analysis shows that global warming is real, and the best explanation of the temperature trend is a combination of volcanoes and CO2."

"Tour Builder is a cool web tool that allows users to create narrative stories using text, graphics, pictures, videos and Google Maps.Tour Builder lets you pick the locations right on the map, add in photos, text, and video, and then share your creation. "

"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."
