People Cause Most US Wildfires

University of Colorado scientist Jennifer Balch and several colleagues came to their conclusion after analyzing reports of 1.6 million wildfires from a comprehensive’s fire occurrence database maintained by the U.S. Forest Service. As shown by the map above, almost all (84 percent) of the fires in the Mediterranean ecosystems of central and southern California, the temperate forests of the eastern United States, and the temperate rainforests of the Pacific Northwest are caused by humans.

The researchers also found that human-ignited fires tripled the length of the wildfire season. Though lightning-ignited fires were clustered in the summer, human-ignited fires occurred in the spring, fall, and winter as well, times when forests tend to be moist. During these seasons, people added more than 840,000 fires - a 35-fold increase over the number of lightning-started fires.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

The Appalachian Mountains, the Scottish Highlands, and the Atlas Mounts in Africa were the same mountain range

The Central Pangean Mountains was a prominent mountain ridge in the central part of the supercontinent Pangaea that extends across the continent from northeast to southwest through the Carboniferous , Permian Triassic periods. The mountains were formed due to a collision within the supercontinents Gondwana and Laurussia during the creation of Pangaea. It was comparable to the present Himalayas at its highest peak during the start of the Permian period. It isn’t easy to assume now that once upon a time that the Scottish Highlands, The Appalachian Mountains, the Ouachita Mountain Range, and the Atlas Mountains in northwestern Africa are the same mountains , once connected as the Central Pangean Mountains.

Moose population in North America

The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range. In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale. In 2014-2015, the North American moose population was measured at around one million animals. The most abundant moose population (about 700,000) lives in Canada. About 300 000 moose remains in nineteen U.S. states Alaska, Colorado, Connecticut, Idaho, Maine, Massachusetts, Minnesota, Montana, Michigan, Nevada, New Hampshire, New York, North Dakota, Oregon, Utah, Vermont, Washington, Wisconsin, and Wyoming. The largest moose specimens are found in Alaska 200 thousand moose. Below the map shows the size of US states scaled by the moose population. Via www.vividmaps.com
