Global Average Temperature: Image title: Land-ocean temperature index, 1880 to present, with base period 1951-1980. The solid black line is the global annual mean and the solid red line is the five-year lowess smooth. The blue uncertainty bars represents the total (LSAT and SST) annual uncertainty at a 95% confidence interval.

Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [1] On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, [2] [3] just below the stratosphere.
A calendar date is a reference to a particular day represented within a calendar system. The calendar date allows the specific day to be identified. The number of days between two dates may be calculated. For example, "25 January 2025" is ten days after "15 January 2025". The date of a particular event depends on the observed time zone.
The Tempestry Project is a collaborative fiber arts project that presents global warming data in visual form through knitted or crocheted artwork. The project is part of a larger "data art" movement and the developing field of climate change art, which seeks to exploit the human tendency to value personal experience over data by creating accessible experiential representations of the data.
Meanwhile, a wide range in annual temperature might suggest the opposite. We could also derive information about a site's ecological conditions through a climograph. For example, if precipitation is consistently low year-round, we might suggest the location reflects a desert; if there is a noticeable seasonal pattern to the precipitation, we ...
Historically, the temperature of the triple point of water was defined as exactly 273.16 K. Today it is an empirically measured quantity. The freezing point of water at sea-level atmospheric pressure occurs at very close to 273.15 K (0 °C).
