Extract of sample "Find an article about weather (within the last 2 years 2012-2014) and summary the article"

due: Climate change and the Dynamic Planet As indicated in chapter 8 in the book Elemental Geosystems by Robert W. Christopherson earth is a dynamic planet whose surface is shaped by active physical agents of change. The chapter states that over time the earths magnetic field together with North Magnetic pole has been changing (255). This drift is caused by earth plate movements and the changes in the distribution of Earths mass. The wobble in the Earths axis during rotation is an integration of the Chandler wobble and the annual wobble, linked to Earths orbit around the sun. Climate is inclined directly to latitude (258). However, with plate movements, comes climate change. This can explain the reason it has become challenging to predict weather and in this case El Niño and La Niña. Global warming in turn is causing melting of the ice sheets, movement of the magnetic pole and the following rise in sea level could bring about an effect on the distribution of mass on the Earths surface (278). This paper seeks to relate the themes of movement, Human-Earth –relationship, and weather in relation to geography. The fickle El Niño of 2014 written by NASA/Jet Propulsion Laboratory will be the article under analysis.
The fickle El Niño of 2014 Summary
Science Daily recently did a feature article on the prediction of another El Niño occurrence in the west America region in 2014. This article is based on information from journals, other organizations such as NASA and as well as universities. According to the article, there were high hopes of another cycle of El Nino in the region, which is mostly a dry area. Earlier in the year hopes were raised as from February through to May when a chain of larger atmospheric west wind burst triggered an earlier series of Kelvin waves (NASA/Jet Propulsion Laboratory, para 1). The situation was short lived though as the warming of the eastern equatorial Pacific by the Kelvin waves dissipated, interfering expectations for an El Niño this year but these latest Kelvin waves have appeared, reviving hopes for a late arrival of the event.
Measurements of sea surface height are a prime indicator in predictions of El Niño and La Niña which have become a part of the long-term, changing condition of global climate (NASA/Jet Propulsion Laboratory, para 2). Climatologist Bill Patzert is convicted that it is too early to be certain for sure. However, he would not be shocked if the current Kelvin waves are the signal for this much-hoped-for El Niño (NASA/Jet Propulsion Laboratory, para 4).
One of the themes of Geography, Human-Earth -relationship, seeks to explain the interaction between people and their environment, how they adapt to the environment and how they change it. It does this by defining how people depend on the environment; how they adapt to the environment and how do they modify the environment.
All in all, in this case scenario, the occurrence of the El Nino is well needed by the residents of the said area as the article seems to point out. This brings out very clearly the human-earth relationship theme by showing how the residents are in need of the rains for their own gain.

Researchers investigate on questions related to transfer from music and visual-art training to children’s performance on specific subjects of verbal and spatial intelligence and executive function, whether training programs would influence executive function, and whether there are links between training programs and changes in verbal or spatial intelligence mediated by changes in executive function (Moreno, et al., 2). In line with the subject of investigation, the researchers formulate four hypotheses, among of which are: music training would improve verbal intelligence independently of spatial...

...?Plastic Sex-Roles in the Common Goby: The Effect of Nest Availability (A Summary) This study of Borg, Forsgren, and Magnhagen (105-115) is about theeffects of nest site availability on reproductive behavior in the common goby (Pomatoschistus microps). Common goby is a small short-lived marine fish having a conventional sex role--that with which the male goby builds nests under empty bivalve shells and cares for the eggs--thus, the availability of good nest sites is an important factor for reproduction. The study was conducted to see if there is a change in sex-roles, related to an environmental-induced change in operational sex ratio, utilizing an experimental artificial nest material in the field situation. More specifically, it sought...

Schweigman, Soto, Wright & Unger (2011) try to fill this gap in the existing literature through a remarkable state-wide sample study among Native American adolescents throughout California to identify how their participation in cultural practices contribute towards their ethnic identity. The results of the study confirm the researchers’ hypothesis that participation in cultural practices has a positive bearing on the ethnic identity of Native American adolescents. The article also...

... Plate Tectonics on Mars Introduction For a number of years now many scientists thought that the idea ofplate tectonic was just another myth and that it never existed within our solar system apart from the Earth, but now some scientists have discovered that behind the geological phenomena which causes the huge movement associated with crustal plate under the planet’s surface also the same happen on Mars. Mars illustrates to us how the earth might have looked many years back because it is still at its primitive stage in terms of plate tectonic. This might be of great important to help us understand with in-depth how plate tectonic processes began happening on earth. Behind this discovery is Yin who was a well known UCLA professor...
