Research says all the risks from these extreme weather events will escalate the more the planet warms. However, IPCC’s Sixth Assessment Report also describes some climate change mitigation strategies, technological developments, and methods for reducing greenhouse gas emissions. How do scientists determine if changes in extreme weather events are linked to climate change? The team spent almost eight weeks (55 days in total) camping on the tundra of Ellesmere Island. During the shoot, they went from 24 hours of daylight to days of half daylight and half darkness, within just a two-month period. They also experienced nearly every kind of weather - from sunshine, to B11 katabatic winds, torrential rain and blizzards. Theo has worked at the BBC Natural History Unit for almost 15 years, and on multiple blue chip landmark series, including Dynasties, Life Story, Planet Earth II and Seven Worlds One Planet. After studying Zoology, his BBC tv career began on the Natural World Strand researching a landmark film about British Butterflies. He then joined the expedition series Lost Land of the Tiger where the team attempted to film tigers in the dense forests of Manas National Park, Bhutan, and high in the Himalaya. For his next project, Theo travelled across 4 continents filming for Sir David Attenborough’s Life Story series. This gave him a further appetite for filming the elusive Bengal tiger. A life’s dream was realised when he worked with veteran producer Miles Barton on Dynasties – Tiger, directing over 200 days in the field. This unique opportunity led to some of the most intimate portraits of tiger family life ever filmed. After so long in the field, Theo took a career break to train as a chef before returning to the NHU and producing Planet Earth III – Extremes. The aptly named Death Valley, in California, USA, is one of the hottest places in the world. The highest temperature ever, 56.7°C (134°F), was recorded there at Greenland Ranch on 10 July 1913.

Few places are more extreme than the Gobi desert where temperatures can range between -30 and +40 degrees Celsius. But the snow leopard has made its home here. This rare and intimate view of a mother and cubs reminds us that the extremes still hold some of planet Earth’s greatest secrets and most spectacular natural wonders. Extra-terrestrial spores and suspended dust are both amongst the varied explanations for red rain. However, after analysing samples in 2015, scientists concluded that it's caused by the presence of microalgae spores from the species Trentepohlia annulata. Snow & Ice Huddling can be a survival superpower, especially in the winter cold of the Atlas Mountains. For a young barbary macaque, separated from the group, it’s vital to find and re-join the huddle before nightfall, but there is a surprising obstacle in his way. The ultimate huddle is found in the mountains of Mexico where millions of monarch butterflies are overwintering. But the calm is shattered when a storm hits their forest shelter.Not to be confused with fire whirls, fire tornadoes are true tornadoes formed from pyrocumulonimbus clouds. Such clouds form over large sources of heat, such as wildfires or volcanic eruptions. Supercells are powerful thunderstorms that form around a mesocyclone (a deep, rotating updraft). They can be several kilometres across and may last several hours, making them the largest thunderstorms in the world as well as the longest-lasting thunderstorms. The Indian state of Kerala experienced multiple showers of red rain between 25 July to 23 September 2001, making the region the first and only place on Earth where it has occurred on three consecutive months. The Sonoran Desert stretches across parts of Arizona and California, USA into the states of Sonora and Baja California, Mexico. It’s annual rainfall ranges from 76-500 mm (2.9-19.6 in) across different regions of the desert. An astonishing 31.1 metres (102 ft) of snow fell on the Paradise region of Mount Rainier National Park, Washington, USA, from 19 February 1971 to 18 February 1972. At a height of 4,392 m (14,410 ft), Rainier has a permanent covering of snow.

Wildfires are notoriously difficult to compare, particularly between those from different eras, as they come in several forms and they can be measured in various ways. Two fires currently share this record title as they are thought to have burned a similar-sized area of forest.Typically, the length of lightning bolts is around 9 km (5.5 mi) or below. Longest lasting lightning flash On 31 October 2019, a single lightning flash spanned a horizontal distance of 709 km (440.6 mi), from north-eastern Argentina and across southern Brazil to the Atlantic Ocean. As our climate changes, extreme weather events are becoming more frequent and often more intense. In light of these changes to the environment, what can audiences take away? Perhaps surprisingly to some, the most hailstorms in a year occur in the Kericho Hills region of Kenya. This area receives hailstorms around 132 days each year, on average.
