Global Warming Explained, In About A Minute : 13.7: Cosmos And Culture Jean-Pierre Clatot/AFP/Getty Images On a pleasant day in 2011, researchers roamed San Diego's public parks in search of volunteers to fill out anonymous surveys about global warming. In the end about 270 responses were collected from a mix of park visitors and nearby community college students. The researchers wanted to know how well the average American understands the basic processes responsible for global warming, and whether there's a relationship between this basic understanding and the belief that global warming is actually occurring. The results were sobering. While a majority of volunteers believed that global warming is a reality (80 percent) and that human activities are a significant contributing factor (77 percent), only a slim minority was able to explain even rudimentary aspects of the mechanism.
Earth Overshoot Day In 8 Months, Humanity Exhausts Earth's Budget for the Year August 20 is Earth Overshoot Day 2013, marking the date when humanity exhausted nature’s budget for the year. We are now operating in overdraft. For the rest of the year, we will maintain our ecological deficit by drawing down local resource stocks and accumulating carbon dioxide in the atmosphere. The Portrayal of Natural Environment in the Evolution of the Ecological Public Health Paradigm 2.1. Public Health and the Environment The environment has long been considered a determinant of health, but the environment conceived simply as the physical things surrounding people does not take into account the reciprocity between the environment and people. Public health has progressed from considerations of the physical environment as an undynamic external entity to a contemporary acceptance of the ecological paradigm. The ecological paradigm recognizes the relations not only between organisms but also between organisms and their physical surroundings. This has largely been a socio-ecological approach with the organisms in question being humans and the focus on the relationships between humans.
Climate change: Rising sea levels hit Maputo, Rotterdam When people talk about the impact of rising sea levels, they often think of small island states that risk being submerged if global warming continues unchecked. But it's not only those on low-lying islands who are in danger. Millions of people live by the sea - and are dependent on it for their livelihoods - and many of the world's largest cities are on the coast. By 2050 the number of people living in delta cities is set to increase by as much as 70%, experts suggest, vastly increasing the number of those at risk. To shed light the impact of rising sea levels, we are taking a close look at two very different cities, Rotterdam and Maputo , and their varying responses to the problem. Much of Rotterdam - Europe's busiest port city - lies several metres below sea level, and this vulnerable position has led it to develop some of the best flood protection in the world.
Desert Ecosystem The Oxford dictionary defines an ecosystem as "a biological community of interacting organisms and their physical environment." In other words, it's a network of plants, animals, and microbes, which work together as a unit in a particular area, and the abiotic factors of that area, such as location, climate, and soil. Though there is no definitive boundary of an ecosystem as such, following its nutrient cycle and energy flow can be helpful if you are to get well-versed with the concept. As for a desert, firstly, it's NOT a barren land devoid of life, as it is usually believed to be.

Australian Stories may contain the names and images of Aboriginal and Torres Strait Islander people now deceased. Australian Stories also contain links to sites that may use images of Aboriginal and Islander people now deceased. Albert Tucker, Last days of Leichhardt, 1964, Harold Mertz Collection, University of Texas. Australia's desert landscapes, regarded as the ‘outback' of Australia, are a powerful symbol of place, and have inspired and helped define Australia's identity. The desert is part of the mythology of rugged survival in a harsh climate.
