Query: What is the warmest part of Russia?
Sochi has a humid subtropical climate (Köppen climate classification "Cfa"), at the lower elevations. Its average annual temperature is during the day and at night. In the coldest months—January and February—the average temperature is about during the day, above at night and the average sea temperature is about . In the warmest months—July and August—the temperature typically ranges from during the day, about at night and the average sea temperature is about . Yearly sunshine hours are around 2,200. Generally, the summer season lasts four months, from June to September. Two months—April and November—are transitional; sometimes temperatures reach , with an average temperature of around during the day and at night. December, January, February and March are the coldest months, with average temperature (of these four months) during the day and at night. Average annual precipitation is about . Sochi lies at 8b/9a hardiness zone, so the city supports different types of palm trees. Sochi is situated on the same latitude as Nice but strong cold winds from Asia make winters less warm. In fact, temperatures drop below freezing every winter. The highest temperature recorded was , on July 30, 2000, and the lowest temperature recorded was on January 25, 1892.
A different use of the term taiga is often encountered in the English language, with "boreal forest" used in the United States and Canada to refer to only the more southerly part of the biome, while "taiga" is used to describe the more barren areas of the northernmost part of the biome approaching the tree line and the tundra biome. Hoffman (1958) discusses the origin of this differential use in North America and why it is an inappropriate differentiation of the Russian term. Although at high elevations taiga grades into alpine tundra through Krummholz, it is not exclusively an alpine biome; and unlike subalpine forest, much of taiga is lowlands.
Taiga is the world's second-largest land biome, after deserts and xeric shrublands, covering or 11.5% of the land area of the Earth. The largest areas are located in Russia and Canada. The taiga is the terrestrial biome with the lowest annual average temperatures after the tundra and permanent ice caps. Extreme winter minimums in the northern taiga are typically lower than those of the tundra. The lowest reliably recorded temperatures in the Northern Hemisphere were recorded in the taiga of northeastern Russia. The taiga or boreal forest has a subarctic climate with very large temperature range between seasons, but the long and cold winter is the dominant feature. This climate is classified as "Dfc", "Dwc", "Dsc", "Dfd" and "Dwd" in the Köppen climate classification scheme, meaning that the short summer (24 h average 10 °C (50 °F) or more) lasts 1–3 months and always less than 4 months. In Siberian taiga the average temperature of the coldest month is between and . There are also some much smaller areas grading towards the oceanic "Cfc" climate with milder winters, whilst the extreme south and (in Eurasia) west of the taiga reaches into humid continental climates ("Dfb", "Dwb") with longer summers. The mean annual temperature generally varies from −5 °C to 5 °C (23 °F to 41 °F), but there are taiga areas in eastern Siberia and interior Alaska-Yukon where the mean annual reaches down to −10 °C (14 °F). According to some sources, the boreal forest grades into a temperate mixed forest when mean annual temperature reaches about 3 °C (37 °F). Discontinuous permafrost is found in areas with mean annual temperature below 0 °C, whilst in the "Dfd" and "Dwd" climate zones continuous permafrost occurs and restricts growth to very shallow-rooted trees like Siberian larch. The winters, with average temperatures below freezing, last five to seven months. Temperatures vary from −54 °C to 30 °C (−65 °F to 86 °F) throughout the whole year. The summers, while short, are generally warm and humid. In much of the taiga, −20 °C (−4 °F) would be a typical winter day temperature and 18 °C (64 °F) an average summer day.
The House of Romanov ruled the Russian Empire from 1721 until 1762, and its matrilineal branch of patrilineal German descent the House of Holstein-Gottorp-Romanov ruled from 1762. At the beginning of the 19th century, the Russian Empire extended from the Arctic Ocean in the north to the Black Sea in the south, from the Baltic Sea on the west to the Pacific Ocean, into Alaska and Northern California in America on the east. With 125.6 million subjects registered by the 1897 census, it had the third-largest population in the world at the time, after Qing China and India. Like all empires, it included a large disparity in terms of economics, ethnicity, and religion. There were numerous dissident elements, who launched numerous rebellions and assassination attempts; they were closely watched by the secret police, with thousands exiled to Siberia.
The Russian Empire, also known as Imperial Russia or simply Russia, was an empire that existed across Eurasia and North America from 1721, following the end of the Great Northern War, until the Republic was proclaimed by the Provisional Government that took power after the February Revolution of 1917.
The war ended in 1721 when an exhausted Sweden sued for peace with Russia. Peter acquired four provinces situated south and east of the Gulf of Finland, thus securing his coveted access to the sea. There, in 1703, he had already founded the city that was to become Russia's new capital, Saint Petersburg, as a "window opened upon Europe" to replace Moscow, long Russia's cultural center. Russian intervention in the Commonwealth marked, with the Silent Sejm, the beginning of a 200-year domination of that region by the Russian Empire. In celebration of his conquests, Peter assumed the title of emperor, and the Russian Tsardom officially became the Russian Empire in 1721.
The ecoregion is approximately contained within the Caspian Depression, and sunken geological region feeding in to the Caspian, the surface of which is itself at below worldwide sea level. The northern section is almost 900 km wide, and stretches up to 300 km inland across Russia and Kazakhstan. The sector along the southeast coast of the Caspian is mostly in Turkmenistan. Elevations throughout the ecoregion range between -28 and +100 meters. The dry areas were once underwater, but as the sea has slowly receded the dry areas have revealed a landscape of sand dunes, ridges, salt domes, salt pans ('shors'), and clay deserts ('takyrs'). 
The climate of the ecoregion is represented by that in the Volga delta, in the Astrakhan Nature Reserve, where the climate is cool semi-arid (Köppen climate classification BSk). This climate is characterized by high variation in temperature, both daily and seasonally; with low precipitation. Average annual precipitation in the Caspian lowlands is 198 mm. Average temperature in January is , and in July is
The ecoregion covers an area about 1,800 km west-east by 1,000 km north-south. The western border is the Lena River; beyond that is the East Siberian taiga ecoregion. The eastern edge is the Kolyma River, beyond which farther east is the Bering tundra ecoregion. To the north is a strip Arctic coastal tundra about 100 km wide, the Northeast Siberian coastal tundra ecoregion. The Okhotsk Sea to the south completes the outline of the ecoregion, but internally the Verhkoyansk and Chersky mountains (which are in the "Cherskii-Kolyma mountain tundra" ecoregion) confines the ecoregion into valleys and lowlands.
The "'Kamchatka-Kurile taiga’" ecoregion (WWF ID:PA0604) is a "conifer island" in the middle of the Kamchatka Peninsula, along the Kamchatka River. It is the easternmost example of Siberian taiga. The region has unusual ecological conditions, a "snow forest" that combines low temperatures, high humidity and boreal forest with heavy snowfall. The local ecology is also affected by volcanic activity. The region is about 300 km long (north-south), and averages about 100 km west-east. It is in the Palearctic ecozone, and mostly in the Boreal forests/taiga ecoregion with a Humid continental climate, cool summer climate. It covers .
The western two-thirds of the border are sparsely populated and traverse largely desert areas, in stark contrast to the western third which is densely populated, containing some of the largest towns in Uzbekistan and southern Kazakhstan. The eastern-most section is mountainous and contains a series of national parks (Sayram-Ugam National Park and Aksu-Zhabagly Nature Reserve in Kazakhstan and Ugam-Chatkal National Park in Uzbekistan. 
Uzbekistan’s Jizzakh to Sirdaryo railway crosses through Kazakhstan briefly, a legacy of the Soviet era where infrastructure was built without regard to what were then internal boundaries.
The Urals montane tundra and taiga ecoregion (WWF ID:PA0610) covers the main ridge of the Ural Mountains (both sides) - a 2,000 km (north-south) by 300 km (west-east) region. The region is on the divide between European and Asian ecoregions, and also the meeting point of tundra and taiga. It is in the Palearctic ecozone, and mostly in the Boreal forests/taiga ecoregion with a Humid continental climate, cool summer climate. It covers .
Christmas in Russia ( "Rozhdestvo Khristovo", in the Russian Orthodox Church called Е́же по пло́ти Рождество Господа Бога и Спа́са нашего Иисуса Христа), commemorating the birth of Jesus Christ, is celebrated on 25 December in the Julian calendar used by the church, which falls on 7 January in the common Gregorian calendar. Christmas is considered a high holiday by the Russian Orthodox Church, one of the 12 Great Feasts, and of only 4 Feasts preceded by a period of fasting. On Christmas Eve, 6 January, there are several long services, including the Royal Hours and Vespers combined with the Divine Liturgy. The family will then return home for the traditional Christmas Eve "Holy Supper", which consists of 12 dishes, one to honour each of the Twelve Apostles. Devout families will then return to church for the "всенощная" All Night Vigil. Then again, on Christmas Morning, for the "заутренняя" Divine Liturgy of the Nativity. Since 1992 Christmas has become a national holiday in Russia, as part of the ten-day holiday at the start of the new year.
In the temperate and polar regions, seasons are marked by changes in the amount of sunlight, which in turn often causes cycles of dormancy in plants and hibernation in animals. These effects vary with latitude and with proximity to bodies of water. For example, the South Pole is in the middle of the continent of Antarctica and therefore a considerable distance from the moderating influence of the southern oceans. The North Pole is in the Arctic Ocean, and thus its temperature extremes are buffered by the water. The result is that the South Pole is consistently colder during the southern winter than the North Pole during the northern winter.
Television is the most popular media in Russia, with 74% of the population watching national television channels routinely and 59% routinely watching regional channels. There are 330 television channels in total. Three channels have a nationwide outreach (over 90% coverage of the Russian territory): Channel One (a.k.a. First Channel), Russia-1 (a.k.a. Rossiya), and NTV. As stated by the BBC, two of the three main federal channels—Channel One and Russia-1—are controlled by the government, while state-controlled energy giant Gazprom owns NTV. According to 2005 television ratings, the most popular channel was Channel One (22.9%), followed by Russia-1 (22.6%). The survey responders' local TV company was third with a rating of 12.3%. The three national TV channels provide both news and entertainment, while the most popular entertainment-only channels are STS (10.3% rating) and TNT (6.7%). The most popular sports channel is Russia 2 (formerly "Sport"; rating 1.8%), while the most popular culture channel is Russia K (formerly "Kultura"; rating 2.5%). Russia K and Russia 2 have the third and fourth largest coverage of all Russian TV channels, with Russia K reaching 78.9% of the urban and 36.2% of the rural population and Russia 2 reaching 51.5% and 15.6%, respectively.
In midsummer, as the sun reaches its maximum elevation of about 23.5 degrees, high temperatures at the South Pole in January average at . As the six-month "day" wears on and the sun gets lower, temperatures drop as well: they reach around sunset (late March) and sunrise (late September). In midwinter, the average temperature remains steady at around . The highest temperature ever recorded at the Amundsen–Scott South Pole Station was on Christmas Day, 2011, and the lowest was on June 23, 1982 (for comparison, the lowest temperature directly recorded anywhere on earth was at Vostok Station on July 21, 1983, though was measured indirectly by satellite in East Antarctica between Dome A and Dome F in August 2010). Mean annual temperature at the South Pole is -49.3 °C (-56.7 °F).
Kazakhstan is located in Central Asia and Eastern Europe at . With an area of about 2,724,800 square kilometers, Kazakhstan is more than twice the combined size of the other four Central Asian states and 60% larger than Alaska. The country borders Turkmenistan, Uzbekistan, and Kyrgyzstan to the south; Russia to the north; Russia and the Caspian Sea to the west; and China's Xinjiang Uygur Autonomous Region to the east.
In 1958 officially the Chechen-Ingush ASSR was restored by a decree direct from Moscow, but in previous 1936 borders. For example, South Ossetia kept the Prigorodny District, instead the republic was "compensated" with ethnic Russian territory on the left-bank Terek, Naursky district and Shelkovsky Districts. Shelkovsky (Moxne in Chechen) in fact had a Chechen heritage before the invasion of the Cossacks, and Naursky (called Hovran in Chechen) also had Chechens in its Eastern regions before the Russian invasion, though the bulk of Naursky may have been instead Kabardins. Nonetheless, the Russian populace (especially the Cossacks) had come, over the years, to view the lands as being theirs, as they had not been dominantly Chechen (or anything besides Cossack) for well over a century at the time of the return of the Chechens.
Ice cap climate is the world's coldest climate, and includes the coldest places on Earth. With an average temperature of , Vostok, Antarctica is the coldest place in the world, and has also recorded the lowest temperature, . The following chart indicates the average and record temperatures in this research station through a year:
Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Most of Antarctica is a polar desert, with annual precipitation of only 200 mm (8 in) along the coast and far less inland. The temperature in Antarctica has reached −89.2 °C (−128.6 °F) (or even −94.7 °C (−135.8 °F) as measured from space), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). Anywhere from 1,000 to 5,000 people reside throughout the year at research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra.
No openly LGBT Russian has been elected to the parliament. The United Russia, Communist Party of the Russian Federation, Liberal Democratic Party of Russia and the A Just Russia are the four major political parties in Russia and they tend to embrace LGBT-rights issues or endorse a progressivist stance in opposition. A similar stance tends to be taken with the smaller political parties. The conservative Patriots of Russia and Right Cause expressly oppose LGBT rights while the liberal Yabloko supports a human rights platform, but generally avoids taking a public stance on LGBT rights.
Kazakhstan is officially a democratic, secular, unitary, constitutional republic with a diverse cultural heritage. Kazakhstan shares borders with Russia, China, Kyrgyzstan, Uzbekistan, and Turkmenistan, and also adjoins a large part of the Caspian Sea. The terrain of Kazakhstan includes flatlands, steppe, taiga, rock canyons, hills, deltas, snow-capped mountains, and deserts. Kazakhstan has an estimated 18.3 million people . Given its large land area, its population density is among the lowest, at less than 6 people per square kilometre (15 people per sq mi). The capital is Astana, where it was moved in 1997 from Almaty, the country's largest city.
Founded by Tsar Peter the Great on 27 May 1703. It became capital of the Russian Empire for more than two hundred years (1712–1728, 1732–1918). St. Petersburg ceased being the capital in 1918 after the Russian Revolution of 1917.
The coastal part of Krasnodar Krai on the Black Sea, most notably in Sochi, possesses a humid subtropical climate with mild and wet winters. In many regions of East Siberia and the Far East, winter is dry compared to summer; other parts of the country experience more even precipitation across seasons. Winter precipitation in most parts of the country usually falls as snow. The region along the Lower Volga and Caspian Sea coast, as well as some areas of southernmost Siberia, possesses a semi-arid climate.
Throughout much of the territory there are only two distinct seasons—winter and summer—as spring and autumn are usually brief periods of change between extremely low and extremely high temperatures. The coldest month is January (February on the coastline); the warmest is usually July. Great ranges of temperature are typical. In winter, temperatures get colder both from south to north and from west to east. Summers can be quite hot, even in Siberia. The continental interiors are the driest areas.
The heat wave during the summer of 2010 was at its worst in June, over the Eastern United States, Middle East, Eastern Europe and European Russia, and over Northeastern China and southeastern Russia. June 2010 marked the fourth consecutive warmest month on record globally, at 0.66 °C (1.22 °F) above average, while the period April–June was the warmest ever recorded for land areas in the Northern Hemisphere, at 1.25 °C (2.25 °F) above average. The previous record for the global average temperature in June was set in 2005 at 0.66 °C (1.19 °F), and the previous warm record for April–June over Northern Hemisphere land areas was 1.16 °C (2.09 °F), set in 2007. The strongest of the anticyclones, the one situated over Siberia, registered a maximum high pressure of 1040 millibars. The weather caused forest fires in China, where three in a team of 300 died fighting a fire that broke out in the Binchuan County of Dali, as Yunnan suffered the worst drought in 60 years by February 17. A major drought was reported across the Sahel as early as January. In August, a section of the Petermann Glacier tongue connecting northern Greenland, the Nares Strait and the Arctic Ocean broke off, the biggest ice shelf in the Arctic to detach in 48 years. By the time the heatwaves had ended in late October 2010, about $500 billion (2011 USD) of damage was done, in the Northern Hemisphere alone.
The climate of Preobrazheniye is monsoon climate, which is moderately warm and humid. Because of the influence of the Primorskoye Current, the winter is warmer than in the continental regions of the region, and the summer is cooler. The warmest months of the year are July, August and September. Spring is long and cool. Autumn, as a rule, comes somewhat slower than in the mainland regions of Russia. The average number of sunshine hours reaches 2,400, with most of them occurring in the winter, while the summer is characterized by a predominance of cloudy weather.
The warmest region in Poland is Lower Silesia in the southwest of the country, where temperatures in the summer average between but can go as high as on some days in the warmest months of July and August. The warmest cities in Poland are Tarnów in Lesser Poland, and Wrocław in Lower Silesia. The average temperatures in Wrocław are in the summer and in the winter, but Tarnów has the longest summer in all of Poland, which lasts for 115 days, from mid-May to mid-September. The coldest region of Poland is in the northeast in the Podlaskie Voivodeship near the borders with Belarus and Lithuania. Usually the coldest city is Suwałki. The climate is affected by cold fronts which come from Scandinavia and Siberia. The average temperature in the winter in Podlaskie ranges from . The biggest impact of the oceanic climate is observed in Świnoujście and Baltic Sea seashore area from Police to Słupsk.
