Climate
Climate is the statistics of weather over long periods of time. It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate differs from weather, in that weather only describes the short-term conditions of these variables in a given region.
Climate Change
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions. Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have been identified as primary causes of ongoing climate change, often referred to as global warming.
Water
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Strictly speaking, water refers to the liquid state of a substance that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity.
Age
Old age is courteous—no one more:
For time after time he knocks at the door,
But nobody says, "Walk in, sir, pray!"
Yet turns he not from the door away,
But lifts the latch, and enters with speed,
And then they cry, "A cool one, indeed."
Johann Wolfgang von Goethe, Old Age.
Age
The ages roll
Forward; and forward with them, draw my soul
Into time's infinite sea.
And to be glad, or sad, I care no more;
But to have done, and to have been, before I cease to do and be.
Owen Meredith (Lord Lytton), The Wanderer, Book IV, A Confession and Apology, Stanza 9.
Water
The rising world of waters dark and deep.
John Milton, Paradise Lost (1667; 1674), Book III, line 11
