Two rainbows emerge from a black storm above the mountains, on August 19, 2014, in Kingman, Arizona. Double tornadoes, lightning storms and rotating supercells – this is what it's like to chase storms for a year. These dramatic images show apocalyptic weather throughout 2014 from a lightning storm to a pair of rainbows. Roger Hill, 57, has been chasing storms in the United States for thirty years and runs a tour operation with his wife Caryn. His favourite photograph of the year was also one of the most difficult to get – as two violent tornadoes tore through Pilger, Nebraska on June 16. The spiraling winds killed a five-year-old girl and injured at least 19 others, and as Roger tried to get the perfect shot debris began to rain down on his car. (Photo by Roger Hill/Barcroft Media)

Located in Siberia, Laka Baikal is the largest freshwater lake on the planet that contains approximately 20 percent of the Earth’s freshwater. Apart from being the oldest lake in the world at over 25 million years old, Lake Baikal is also home to over two thousand varieties of flora and fauna, of which almost 1,600 are endemic to the lake. The water of Lake Baikal is renowned for being some of the clearest in the world. When the lake freezes during the winter, an amazing phenomena takes place: large shards of transparent ice form on the surface of the lake, giving the amazing appearance of turquoise ice.
