Rainforest Rainforests are forests characterized by high rainfall, with annual rainfall between 250 and 450 centimetres (98 and 177 in).[1] There are two types of rainforest: tropical rainforest and temperate rainforest. The monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earth's tropical rainforests. Tropical Tropical rainforests are characterized by a warm and wet climate. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year.[5] Average annual rainfall is no less than 168 cm (66 in) and can exceed 1,000 cm (390 in) although it typically lies between 175 cm (69 in) and 200 cm (79 in).[6] Many of the world's rainforests are associated with the location of the monsoon trough, also known as the intertropical convergence zone.[7] Tropical rainforests are located in the tropics, i.e., in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn.

Larson in the Illinois State By 16,000 years ago the height of the last major glaciation The landscape of the Midwest was very different 16,000 years ago. Although glaciers were retreating, much of the midwestern U.S. was still under ice. Sixteen thousand years ago the climate was quite different in the area. Because of the cooler climate, many of the plants and animals that inhabited the area around 16,000 years ago were different than those found in the region today. The reconstruction shows several mastodons feeding in wetlands in a parkland dominated by spruce and balsam (poplar or aspen). Here ISM Curator of Geology Dr. Boney Spring is one of a series of spring deposits excavated by personnel from the Illinois State Museum, the University of Missouri, University of Arizona, and Southern Methodist University between 1965 and 1980.

Nuclear Information and Resource Service Best Way - Amazon Rainforest Survival Guide Despite the fact the Amazon rainforest is progressively dwindling due to deforestation, it is still vast and people find themselves needing to survive in it on a regular basis. So it is important to know how to survive in this type of seemingly impenetrable, endless jungle if you are unfortunate enough to find yourself stranded there for an extended period of time. While access to food and water are the first concerns, keeping yourself safe from wild animals and knowing what not to consume is also important. Water Considerations While it is a rainforest, which by definition means it rains regularly, it is still rather difficult to obtain water which is not contaminated and is safe for you to drink. Edible Plants There are many plants or fruits from these plants which can be eaten. Animal Hunting and Protection It is also important to set traps for animals, not only to catch them but to protect yourself from them at night. More slideshows

How Everything Works Dahr Jamail | As Climate Disruption Advances, 26 Percent of Mammals Face Extinction (Image: Polar bear, air pollution via Shutterstock; Edited: JR/TO) Two recently released studies brought bad news for those living near coastlines around the world. One published in the peer-reviewed Nature Climate Change, the other in the Proceedings of the National Academy of Sciences, the studies showed that existing computer models might have severely underestimated the risk to the Greenland ice sheet from warming global temperatures. Bear in mind that if Greenland's entire ice sheet melts, 20 feet would be added to global sea levels. As if that isn't enough of an indicator of how fast anthropogenic climate disruption (ACD) is happening across the globe, two days after delegates from more than 190 countries had gathered in Peru at the annual climate summit, the World Meteorological Organization reported that 2014 was tied with 2010 as the hottest year on record, and rejected popular claims that global warming had "paused."

Rainforest Animals Engineers Edge Loggers Accidentally Cut Down World’s Oldest Tree in Amazon Forest World News Daily Report Environment Illegal loggers at the frontier of the Peruvian and Brazilian border have mistakenly cut down what experts claim is the world’s oldest tree after allegedly not noticing they were logging deeply in Matsés Indigenous Reserve, an area where logging is illegal, infuriating local conservation organizations and native indigenous communities. The giant Samauma tree that is thought to be over 5,800 years old judging on its concentric rings and estimated to be close to 40 meters in height was a major part of the native tribes cultural landscape, countless generations of natives having witnessed the long duration of the tree and having included it in their own culture. «It is the Mother spirit of the rainforest, from this spirit-tree came the life force of all things living. Native communities alarmed local media outlets and conservation groups when Aotlcp-Awak, or Mother tree in local dialects, was reported sawed down by heavy machinery
