Also called global warming denial. climate change feedback A natural phenomenon that may increase or decrease the warming that eventually results from a change in radiative forcing. climate change mitigation approaches to limit global warming, primarily by the substitution of fossil fuels with low-carbon sources of energy climate commitment How much future warming is "committed", even if ...
A Köppen–Geiger climate map showing temperate climates for 1991–2020 The different geographical zones of the world. The temperate zones, in the sense of geographical regions defined by latitude, span from either north or south of the subtropics (north or south of the orange dotted lines, at 35 degrees north or south) to the polar circles.
The environmental effects of climate change are broad and far-reaching, affecting oceans, ice, and weather. Changes may occur gradually or rapidly. Changes may occur gradually or rapidly. Evidence for these effects comes from studying climate change in the past, from modelling, and from modern observations. [ 186 ]
Climate variability is the term to describe variations in the mean state and other characteristics of climate (such as chances or possibility of extreme weather, etc.) "on all spatial and temporal scales beyond that of individual weather events."
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.
The oceanic climate, also known as a marine climate, is characterized by warm summers in which the average daily temperature in the warmest month is below 22 °C (72 °F). In addition, at least 4 months have a mean monthly temperature above 10 °C (50 °F). [ 2 ]
Body proportions of select modern human population groups in relation to temperature. Mean index of tibia/femur length (crural index). [10]Bergmann's rule states that endothermic animal subspecies living in colder climates have larger bodies than those of the subspecies living in warmer climates. [11]
Within the weathering environment, chemical oxidation of a variety of metals occurs. The most commonly observed is the oxidation of Fe 2+ by oxygen and water to form Fe 3+ oxides and hydroxides such as goethite, limonite, and hematite. This gives the affected rocks a reddish-brown coloration on the surface which crumbles easily and weakens the ...
