This bike doesn’t just help the environment by cutting down on automobile pollution, it also helps reduce pollution from others as well. While the bike is in motion, the polluted air passes through a filter which removes harmful particulates. The frame of the bike will collect energy from the sun and convert it into fresh oxygen to be released back into the environment.

Scientists use climate models to predict how Earth’s climate will change. Climate models are computer programs with mathematical equations. They are programmed to simulate past climate as accurately as possible. This gives scientists some confidence in a climate model’s ability to predict the future.
Climate models predict that Earth’s average temperature will keep rising over the next 100 years or so. There may be a year or years where Earth’s average temperature is steady or even falls. But the overall trend is expected to be up.
Earth’s average temperature is expected to rise even if the amount of greenhouse gases in the atmosphere decreases. But the rise would be less than if greenhouse gas amounts remain the same or increase.
Take a look at this amazing visualization that explains how we’ve treated the Earth over the past 100 years and what the next 100 might hold.
Have you ever tried to convey the feeling of walking through your favorite park? Or have you wanted to create a virtual tour of your business to attract customers? Well, starting today, it’s now possible for you to build your own Street View experiences to do just that. Using a new feature in our Views community, you can easily connect your photo spheres to create 360º virtual tours of the places you love, then share them with the world on Google Maps.
To get started, just create photo spheres using your Android phone or a DSLR and then share them on Views. Next, select the photo spheres from your profile and use our new tool to connect them together (as seen in the example above). Once your photo spheres are connected and published, people can navigate between them on Google Maps, just like they can in Street View. Please visit the help center to learn more about connecting photo spheres.
Google are excited to see the different types of Street View experiences that everyone will contribute. For example, this feature can now enable environmental non-profits to document and promote the beautiful places they strive to protect. It also opens up a new tool for photographers to showcase diversity in a specific location — by times of day, weather conditions or cultural events — in a way that Street View currently doesn’t cover.
And, just like with Street View, you can embed Google’s interactive viewer on your own website or build applications with it using the Google Maps API. You can learn more about solutions for developers.
It is being hoped that this new feature will enable people to share and witness the beauty and breadth of our planet through Google Maps. Whether you’re photographing exotic islands or your favorite neighborhood hangout, mountain peaks or city streets, historic castles or your own business, we’re thrilled to see the places you love coming to life on Google Maps.
Dr. Matthew Hansen at the University of Maryland, we’ve built the first detailed maps of the world’s forests, from 2000-2012, documenting and quantifying forest landscape changes such as fires, tornadoes, disease and logging.
The most significant findings were that the overall rate of tropical deforestation is increasing, and global forests have experienced a net loss of 1.5M sq km during 2000-2012 due to both natural (disturbance) and human causes. That’s a loss of forested land comparable in size to the entire state of Alaska.
A little more than 300,000 square miles of forest was established or replanted worldwide between 2000 and 2012. Unfortunately, almost 900,000 square miles was destroyed during the same time period — logged, ravaged by fire, or attacked by insects.
Those are the main conclusions of a study that examined hundreds of thousands of images snapped by the U.S. government’s Landsat satellites. Academic researchers partnered with Google staff to produce stunning maps displaying the world’s forests and areas that have been deforested or reforested since 2000. Those maps were used to produce the following short videos:
About a third of the deforestation occurred in the tropics, and half of that was in South America. Logging and clearing of land for farming were responsible for much of the loss. Hearteningly, the researchers found that deforestation has been slowing down in Brazil, where worldwide concerns about the loss of the Amazon have helped spur domestic efforts to save the rainforest. But that slowdown was offset by increasing losses in other countries.
“Although Brazilian gross forest loss is the second highest globally, other countries, including Malaysia, Cambodia, Cote d’Ivoire, Tanzania, Argentina, and Paraguay, experienced a greater percentage of loss of forest cover,” the scientists wrote in the paper, published Thursday in Science. “Given consensus on the value of natural forests to the Earth system, Brazil’s policy intervention is an example of how awareness of forest valuation can reverse decades of previous wide-spread deforestation.”
The tropics lost more forest cover during the study period than any other region. The second-worst hit were the boreal forests of spruce, fir, and larch in and around the Arctic, with fire the leading cause. Previous research has shown that these forests are burning at a rate not seen in at least 10,000 years, with climate change increasing temperatures and drying out the landscape.
That wasn’t the only worrisome climate-related finding in the new paper. The mountains of the American West are losing forests due not only to logging, but also because of fire and disease — with mountain pine bark beetles marching up mountains as temperatures warm, feasting on banquets of ill-prepared pines.
The loss of forests is making it even more difficult for the Earth to suck back up all the carbon dioxide that we’re pumping into its atmosphere.

Here are some tips you can try out in ArcMap right away. The 10 shortcuts below can shave milliseconds off common tasks, and hey, milliseconds count when you’re trying to get stuff done. You just may be able to get to lunch five minutes earlier and beat the crowd.
Working with Maps
- To activate a data frame, hold down the Alt key and click the data frame name.
- To create a copy of a layer within the same data frame, hold down the Ctrl key and drag the layer up or down. If multiple layers are selected, you can copy all of them at the same time by Ctrl-dragging. (When dragging a layer into a different data frame, the layer is copied by default. If you want to move a layer to a different data frame, hold down Ctrl while you drag it to the new data frame.)
- Hold down the Alt key and click a layer name to zoom to the extent of that layer.
- Select (click) a layer and press Enter to open its layer properties dialog box.
- Hold down the C key while any tool is active to pan the map. Hold down X to zoom out, and Z to zoom in. This shortcut is especially useful when you need to select features that are geographically disbursed.
Working with Tables
To quickly open a table, hold down the Ctrl key and double-click a layer or table in the Table of Contents; alternatively, select the layer or table and press Ctrl+T.
Outside of an edit session, press the spacebar to select or unselect a row.
Press Ctrl+U to switch (reverse) a selection.
Double-click a field name to sort the field in ascending order. Double-click the field name again to sort in descending order.
Click a field name and press Ctrl+H to turn off (hide) the field. (To display the field again, go to the layer properties dialog box > Fields tab, check the field name, and click OK.)
