National Geographic Headquarters The famed Northwest Passage, the treacherous route connecting the North Atlantic and North Pacific ocean basins, is now habitually free of ice and safe enough for cruise ships to navigate.Melting glaciers and ice sheets, as well as expansion of seawater as it warms, have contributed to unprecedented sea level rise. In a broader sense, climate is the state of the components of the climate system, which includes the ocean and ice on Earth. region that experience cool summers and snowy winters. region generally located between the Tropic of Cancer (23 1/2 degrees north of the Equator) and the Tropic of Capricorn (23 1/2 degrees south of the Equator). Climates around the world were changed for years. Some climates are small in scale, like the climate of a local region or the microclimates within an ecosystem, and some are much larger, such as the climates of entire continents, or the world’s oceans. an animal that lives most of its life in the ocean but breathes air and gives birth to live young, such as whales and seals. ocean conveyor belt system in which water moves between the cold depths and warm surface in oceans throughout the world.

In these parts of the world, climate is influenced mostly by latitude and a region’s position on the continent.MediterraneanMediterranean climates have warm summers and short, mild, rainy winters. Cities on the southern side of Lake Ontario, for example, are cloudier and receive much more snow than cities on the northern shore. A region’s elevation, proximity to the ocean or freshwater, and land-use patterns can all impact climate.All climates are the product of many factors, including latitude, elevation, topography, distance from the ocean, and location on a continent.

History and Pre-Historic Information 4. climate characterized by a moderate amount of heat. What is the difference between weather and climate? Different places have different climates. The current period of climate change is sometimes called “global warming.”Global warming is often associated with a runaway “greenhouse effect.” The greenhouse effect describes the process of certain gases (including carbon dioxide (CO2), methane, nitrous oxide (N2O), fluorinated gases, and ozone) trapping solar radiation in a planet's lower atmosphere. The cryosphere is another generally consistent part of the climate system. However, human activities that include burning fossil fuels and cutting down forests release greenhouse gases into the atmosphere at an unprecedented rate.The current period of climate change has been documented by rising temperatures, melting glaciers, and more intense weather phenomena.Our planet’s temperature has risen about 1.1° C (2° F) since the late 19th century.

Home to the ancient civilizations of Sumer, Assyria, and Babylonia these peoples are credited with influencing mathematics and astronomy. People living in these regions depend on the seasonal rains to bring water to their crops. This “ocean conveyor belt” has an enormous influence on marine ecosystems and biodiversity.Topography, Topography and vegetation influence climate by helping determine how the Sun’s energy is used on Earth. Skies are mostly clear and precipitation is low. The abundance of plants and the type of land cover (such as soil, sand, or asphalt) impacts evaporation and ambient temperature.The biosphere, the sum total of living things on Earth, profoundly influences climate. a violently rotating column of air that forms at the bottom of a cloud and touches the ground. Climate is the long-term average of weather, typically averaged over a period of 30 years.

The different kinds of weather you might experience in these regions are caused by moving patterns in the Earth’s atmospheric and oceanic circulation, unequal heating of the Earth, and the rotation of the Earth on its tilted axis. Despite the harsh conditions animals and plants have developed adaptive methods to survive the environment. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. Look to its ancient cousins. A similar band of deserts lies to the south in Australia, South America, and southern Africa. Yurts protect residents from fierce winds, and their portability makes them an ideal structure for nomadic and seminomadic herding cultures on the grassland. Hurricanes are the same thing as typhoons, but usually located in the Atlantic Ocean region. Most arid climates receive 10 to 30 centimeters (four to 12 inches) of rain each year, and semiarid climates receive enough to support extensive grasslands.Temperatures in both arid and semiarid climates show large daily and seasonal variations.

Americans want more renewable energy. In regions with mild climates, the increased atmospheric moisture associated with humid climates may increase the likelihood of hurricanes and typhoons.Climate change is also impacting organisms and species range. By and large, the high-latitude climates are climates of the northern hemisphere, occupying the northern subarctic and arctic latitude zones.But they also extend southward into the midlatitude zone as far south as about the 47th parallel in eastern North America and eastern Asia.
