| Dust Bowl Dust Bowl or the Dirty Thirties was a period of severe dust storms causing major ecological and agricultural damage to American and Canadian prairie lands from 1930 to 1936 (in some areas until 1940). The phenomenon was caused by severe drought coupled with decades of extensive farming without crop rotation or other techniques to prevent erosion. Dust_Bowl

| California Sea Lion The California Sea Lion (Zalophus californianus) is a coastal sea lion of the northern Pacific Ocean. Their numbers are abundant (188,000 U.S. stock 1995 est.), and the population continues to expand at a rate of approximately 5.0% annually. They are quite intelligent, can adapt to man-made environments, and even adult males can be easily trained. California_Sea_Lion

| Geography of California geography of California is diverse. There are alpine mountains, foggy coastlines, hot deserts, and a fertile central valley. The U.S. state of California is home to some of the world's most exceptional treescoast redwood), most massive (Giant Sequoia), and oldest (bristlecone pine). It is also home to both the highest (Mt. Whitney) and lowest (Death Valley) points in the 48 contiguous states. Geography_of_California

| Decompression sickness Decompression sickness, (DCS) (also historically or colloquially known as divers' disease, the bends or caisson disease) describes a condition arising from the precipitation of dissolved gasses into bubbles inside the body on depressurisation. DCS most commonly refers to a specific type of scuba diving hazard but may be experienced in other depressurisation events such as caisson working, flying in unpressurised aircraft and extra-vehicular activity from spacecraft.

| Lightning Lightning is an atmospheric discharge of electricity usually accompanied by thunder, which typically occurs during thunderstorms, and sometimes during volcanic eruptions or dust storms. In the atmospheric electrical discharge, a leader of a bolt of lightning can travel at speeds of , and can reach temperatures approaching , hot enough to fuse silica sand into glass channels known as fulgurites which are normally hollow and can extend some distance into the ground.

| Climate change and agriculture Climate change and agriculture are interrelated processes, both of which take place on a global scale. Global warming is projected to have significant impacts on conditions affecting agriculture, including temperature, precipitation and glacial run-off. These conditions determine the carrying capacity of the biosphere to produce enough food for the human population and domesticated animals. Climate_change_and_agriculture

It was created by the Joint Photographic Experts Group committee in the year 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard (created 1992). The standardized filename extension is .jp2 for ISO/IEC 15444-1 conforming files and .jpx for the extended part-2 specifications, published as ISO/IEC 15444-2. The registered MIME types are defined in RFC 3745. For ISO/IEC 15444-1 it is image/jp2. JPEG_2000

| Pascal (unit) The pascal (symbolPa) is the SI derived unit of pressure, stress, Young's modulus and tensile strength. It is a measure of force per unit area, equivalent to one newton per square metre or one joule per cubic metre. In everyday life, the pascal is perhaps best known from meteorological barometric pressure reports, where it occurs in the form of hectopascals atmospheric pressure (near sea level). One hectopascal is equivalent to one millibar; one atmosphere is equal to 1013.25 hPa. Pascal_(unit)

| Datum (geodesy) This article describes a concept from surveying and geodesy. For other meanings, see Datum (disambiguation). A geodetic datum (plural datums, not data) is a reference from which measurements are made. In surveying and geodesy, datum is a set of reference points on the earth's surface against which position measurements are made, and (often) an associated model of the shape of the earth (reference ellipsoid) to define a geographic coordinate system.

| Surface weather analysis Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations. Weather maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temperature, and cloud cover onto a geographical map to help find synoptic scale features such as weather fronts.

| Weather forecasting Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. Human beings have attempted to predict the weather informally for millennia, and formally since at least the nineteenth century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere and using scientific understanding of atmospheric processes to project how the atmosphere will evolve.

| Hagfish Hagfish are marine craniates of the class Myxini, also known as Hyperotreti. Myxini is the only class in the clade Craniata that does not also belong to the subphylum Vertebrata. That is, they are the only animals which have a skull but not a vertebral column.Despite their name, there is some debate about whether they are strictly fish (as there is for lampreys), since they belong to a much more primitive lineage than any other group that is placed in the category of fish (Chondrichthyes and Osteichthyes).

| Estuary estuary is a semi-enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea. They are affected by both marine influences, such as tides, waves, and the influx of saline water; and riverine influences, such as flows of fresh water and sediment. As a result they may contain many biological niches within a small area, and so are associated with high biological diversity. Estuary

Magnetism varies from place to place and differences in Earth's magnetic field (the magnetosphere) can be caused by the differing nature of rocks and the interaction between charged particles from the Sun and the magnetosphere of a planet. Magnetometers are often a frequent component instrument on spacecraft that explore planets. Magnetometer
