Climate Change Impact on Storms Scientific research indicates that climate change will cause hurricanes and tropical storms to become more intense — lasting longer, unleashing stronger winds, and causing more damage to coastal ecosystems and communities. Scientists point to higher ocean temperatures as the main culprit, since hurricanes and tropical storms get their energy from warm water. As sea surface temperatures rise, developing storms will contain more energy. At the same time, other factors such as rising sea levels, disappearing wetlands, and increased coastal development threaten to intensify the damage caused by hurricanes and tropical storms.
A Terrifying, Fascinating Timelapse of 30 Years of Human Impact on Earth - Emily Badger A new interactive project from Google, NASA and the US Geological Survey. Since the 1970s, NASA and the U.S. Geological Survey have been amassing satellite images of every inch of our planet as part of the Landsat program. Over time, the images reveal a record of change: of cities expanding, lakes and forests disappearing, new islands emerging from the sea off the coast of rising Middle East metropolises like Dubai. Tropical storms - Impacts - Exploring Climate Change Tropical storms have the potential to do great damage, especially on islands and coastal continental areas. Their names reflect where they form, hurricanes in the North Atlantic and Caribbean, typhoons in the Pacific, and tropical cyclones over Australia. Tropical storms frequently hit the headlines, never more so than when Hurricane Katrina devastated New Orleans in 2005. The hurricane killed at least 1,800 people and caused an estimated $81 billion worth of damage, making Katrina the costliest natural disaster in history. One of the results of Hurricane Katrina was to focus the world’s attention on the role of climate change in the intensity and frequency of hurricanes and other tropical storms. The debate became polarised, with the US Government denying climate change played any role and some extreme views claiming the storm and its intensity were a direct result of higher temperatures.
Welcome to Recycle City You are Dumptown's new City Manager! When you begin, you'll see Dumptown at its worst — it's littered, polluted, and nothing is being recycled or reused. There's more to Recycle City than just sightseeing! Try some of these activities. Saffir-Simpson Hurricane Wind Scale The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane's sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage. Category 1 and 2 storms are still dangerous, however, and require preventative measures. In the western North Pacific, the term "super typhoon" is used for tropical cyclones with sustained winds exceeding 150 mph.
8 maps that explain why Typhoon Haiyan hit the Philippines so hard A week after Typhoon Haiyan made landfall in the Philippines, the country's crisis is far from over, with perhaps thousands of dead still be counted, tens or hundreds of thousands of people displaced and basic services, including access to food, shut down in many areas. To help convey how and why the storm was so bad, here is a series of eight maps on Haiyan, its impact and the Philippines' crisis. 1. The storm's path across Southeast Asia This map shows Haiyan's path westward across the Pacific. The numbers indicate the size of the storm, which peaked just as it hit the central Philippines. Apps That Challenge Kids to Solve Environmental Issues By Tanner Higgin, Graphite Environmental education for most adults used to mean learning a little bit about recycling and planting some trees on Arbor Day. We didn’t delve into ecology as much as we skimmed the surface. But things have gotten more complex since then, and the topic of climate change has brought environmental education to the forefront. At its best, environmental education gets students grappling with big, cross-disciplinary issues like sustainable design and renewable energy.
Virtual Earthquake - An Introduction What's an earthquake? Earthquakes occur because of a sudden release of stored energy. This energy has built up over long periods of time as a result of tectonic forces within the earth. Most earthquakes take place along faults in the upper 25 miles of the earth's surface when one side rapidly moves relative to the other side of the fault. This sudden motion causes shock waves (seismic waves) to radiate from their point of origin called the focus and travel through the earth. Modernizing weather forecasts and disaster planning to save lives Is it hot outside? Should I bring an umbrella? Most of us don’t think much beyond these questions when we check the weather report on a typical day. But weather information plays a much more critical role than providing intel on whether to take an umbrella or use sunscreen.
7 Crazy Things That Happen Only When It's Really Cold The cold is so delightful, well, it can be. In fact, plenty of wacky phenomena, from frost quakes and frozen soap bubbles to square tires and soda slushies, are possible, or practical, only when temperatures dip below freezing. So as you stay toasty indoors, free of frostbite, check out these 7 "cool" effects of sub-zero temperatures. [Photos: The 8 Coldest Places on Earth] 1.
