m.fastcompany Low-lying island atolls—which are home to half a million people around the world—are some of the places most immediately threatened by rising sea levels. Now an unsettling new study from the U.S. Geological Survey shows that these vulnerable places could disappear at rates almost double what scientists had previously realized. These islands, especially ones surrounded by shallow coral reef, are vulnerable to rising waters in several ways. First, sea level rise itself will eat into their coastline.

National geographic Geography is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earth’s surface and the human societies spread across it. They also examine how human culture interacts with the natural environment, and the way that locations and places can have an impact on people. Geography seeks to understand where things are found, why they are there, and how they develop and change over time. Ancient Geographers The term "geography" comes to us from the ancient Greeks, who needed a word to describe the writings and maps that were helping them make sense of the world in which they lived.

GBIF : Global Biodiversity Information Facility Try out the new GBIF portal! Why not try out the new GBIF portal at www.gbif.org, which has many more features and includes lots of information about the GBIF community, including great examples of data uses in research and interesting applications? The old GBIF data portal which you are viewing now will continue to be supported until we are satisfied it can be taken down without causing major inconvenience. Be aware that the content here is static and has not been updated since the launch of the new portal on 9 October 2013. See Earth’s Temperature Spiral Toward 2°C The steady rise of Earth’s temperature as greenhouse gases accumulate in the atmosphere and trap more and more heat is sending the planet spiraling closer to the point where warming’s catastrophic consequences may be all but assured. That metaphoric spiral has become a literal one in a new graphic drawn up by Ed Hawkins, a climate scientist at the University of Reading in the United Kingdom. The animated graphic features a rainbow-colored record of global temperatures spinning outward from the late 19th century to the present as the Earth heats up.

The Biodiversity Hotspots Page Content Life on Earth faces a crisis of historical and planetary proportions. Unsustainable consumption in many northern countries and crushing poverty in the tropics are destroying wild nature. Biodiversity is besieged. Extinction is the gravest aspect of the biodiversity crisis: it is irreversible. While extinction is a natural process, human impacts have elevated the rate of extinction by at least a thousand, possibly several thousand, times the natural rate.

takepart A city that loves politics nearly as much as it loves food, Paris is a place where a bistro dinner might feature both debate and an excellent steak frites. At the end of this year, however, what’s on the plate at one Parisian dinner will be central to the politicking and negotiation going on at the United Nation’s climate change summit. Some 25,000 delegates are meeting in Paris to hammer out the final details on a climate change treaty, and as Civil Eats reports, former White House chef Sam Kass is hoping to show them how food is tied up with greenhouse gas emissions—and how it can help reduce them. Kass will serve a sequel to the lunch he and chef Dan Barber prepared at the U.N.

Rate of environmental degradation puts life on Earth at risk, say scientists Humans are “eating away at our own life support systems” at a rate unseen in the past 10,000 years by degrading land and freshwater systems, emitting greenhouse gases and releasing vast amounts of agricultural chemicals into the environment, new research has found. Two major new studies by an international team of researchers have pinpointed the key factors that ensure a livable planet for humans, with stark results. Of nine worldwide processes that underpin life on Earth, four have exceeded “safe” levels – human-driven climate change, loss of biosphere integrity, land system change and the high level of phosphorus and nitrogen flowing into the oceans due to fertiliser use.

Co-Existence To put it to you plainly and not beat around the bush, I have always expected myself to do something GREAT. Something BIG. Actually about doing a lot of GREAT and BIG things. Of creating something of value, worthy of this world. It is perhaps why I embarked on this journey right now and have on so many other occasions in my life. A constant search for fulfilling my expectations. Wal-Mart Stores - Global 500 2014 Companies are ranked by total revenues for their respective fiscal years ended on or before March 31, 2015.
