The gorgeous lighting of the original
release has also been improved with added shaders, while each lightning strike
during thunderstorms will flash the island in a beautiful bright light, creating a great sense of atmosphere.
Both wetland drying and the increased frequency of warm dry summers and associated
thunderstorms have led to more large fires in the last ten years than in any decade since record - keeping began in the 1940s.9 In Alaskan tundra, which was too cold and wet to support extensive fires for approximately the last 5,000 years, 105 a single large fire in 2007
released as much carbon to the atmosphere as had been absorbed by the entire circumpolar Arctic tundra
during the previous quarter - century.106 Even if climate warming were curtailed by reducing heat - trapping gas (also known as greenhouse gas) emissions (as in the B1 scenario), the annual area burned in Alaska is projected to double by mid-century and to triple by the end of the century, 107 thus fostering increased emissions of heat - trapping gases, higher temperatures, and increased fires.
