Winter is the coldest season of the year in polar and temperate climates, between autumn and spring.
 Winter is caused by the axis of the Earth in that hemisphere being oriented away from the Sun.
 Different cultures define different dates as the start of winter, and some use a definition based on weather.
 When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa.
 In many regions, winter is associated with snow and freezing temperatures.
 The moment of winter solstice is when the sun's elevation with respect to the North or South Pole is at its most negative value (that is, the sun is at its farthest below the horizon as measured from the pole), meaning this day will have the shortest day and the longest night.
 The earliest sunset and latest sunrise dates outside the polar regions differ from the date of the winter solstice, however, and these depend on latitude, due to the variation in the solar day throughout the year caused by the Earth's elliptical orbit (see earliest and latest sunrise and sunset).
Tanacetum is a genus of about 160 species of flowering plants in the aster family, Asteraceae, native to many regions of the Northern Hemisphere.
 They are known commonly as tansies.
 The name tansy can refer specifically to "Tanacetum vulgare", which may be called the common tansy or garden tansy for clarity.
Polytrichum commune (also known as common haircap, great golden maidenhair, great goldilocks, common haircap moss, or common hair moss) is a species of moss found in many regions with high humidity and rainfall.
 The species can be exceptionally tall for a moss with stems often exceeding 30 cm though rarely reaching 70 cm , but it is most commonly found at shorter lengths of 5 to .
 It is widely distributed throughout temperate and boreal latitudes in the Northern Hemisphere and also found in Mexico, several Pacific Islands including New Zealand, and also in Australia.
 It typically grows in bogs, wet heathland and along forest streams.
Chthamalus (χθαμαλός, "flat" or "on the ground") is a genus of barnacles that is found along almost all coasts of the northern hemisphere, as well as many regions in the southern hemisphere.
 These small barnacles have been studied in part because of the taxonomic confusion over a group of species that, by and large, are morphologically and ecologically quite similar.
 In recent years, molecular techniques have identified a number of cryptic species that have been subsequently confirmed by taxonomists using morphological measurements.
 Most recently the genus has been shown to be paraphyletic, with the genus "Microeuraphia" nested within "Chthamalus".
Temperate deciduous forests or temperate broad-leaf forests are dominated by trees that lose their leaves each year.
 They are found in areas with warm moist summers and mild winters.
 The three major areas of this forest type occur in the Northern Hemisphere: eastern North America, East Asia, and Europe.
 Smaller areas occur in Australasia and southern South America.
 Examples of typical trees in the Northern Hemisphere's deciduous forests include oak, maple, beech, and elm, while in the Southern Hemisphere, trees of the genus "Nothofagus" dominate this type of forest.
 The diversity of tree species is higher in regions where the winter is milder, and also in mountainous regions that provide an array of soil types and microclimates.
 The largest intact, temperate deciduous forest in the world is protected inside of the six-million-acre Adirondack Park in Upstate New York.
The 2010 Northern Hemisphere summer heat waves included severe heat waves that impacted most of the United States, Kazakhstan, Mongolia, China, Hong Kong, North Africa and the European continent as a whole, along with parts of Canada, Russia, Indochina, South Korea and Japan during May, June, July, and August 2010.
 The first phase of the global heatwaves was caused by a moderate El Niño event, which lasted from June 2009 to May 2010.
 The first phase lasted only from April 2010 to June 2010, and caused only moderate above average temperatures in the areas affected.
 But it also set new record high temperatures for most of the area affected, in the Northern Hemisphere.
 The second phase (the main, and most devastating phase) was caused by a very strong La Niña event, which lasted from June 2010 to June 2011.
 According to meteorologists, the 2010–11 La Niña event was one of the strongest La Niña events ever observed.
 That same La Niña event also had devastating effects in the Eastern states of Australia.
 The second phase lasted from June 2010 to October 2010, caused severe heat waves, and multiple record-breaking temperatures.
 The heatwaves began on April 2010, when strong anticyclones began to develop, over most of the affected regions, in the Northern Hemisphere.
 The heatwaves ended in October 2010, when the powerful anticyclones over most of the affected areas dissipated.
Actaea, commonly called baneberry, bugbane and cohosh, is a genus of flowering plants belonging to the family Ranunculaceae, native to subtropical, temperate and subartic regions of the Europe, Asia and North America.
June is the sixth month of the year in the Julian and Gregorian calendars and the second month to have the length of 30 days. June contains the summer solstice in the Northern Hemisphere, the day with the most daylight hours, and the winter solstice in the Southern Hemisphere, the day with the fewest daylight hours (excluding polar regions in both cases).
 June in the Northern Hemisphere is the seasonal equivalent to December in the Southern Hemisphere and vice versa.
 In the Northern hemisphere, the beginning of the traditional astronomical summer is 21 June (meteorological summer begins on 1 June).
 In the Southern hemisphere, meteorological winter begins on 1 June.
Elaphe is one of the main genera of the rat snakes, which are found in many regions of the northern hemisphere.
 "Elaphe" are medium to large constrictors by nature.
 All species are nonvenomous.
 Although all of the species in "Elaphe" are nonvenomous, bites from rat snakes are still irritably painful and can potentially cause bacterial infections due to the saliva.
Salpiglossis is a genus of the botanical family Solanaceae.
