Higher temperatures increase the amount of moisture that evaporates from land and water, leading to drought in many areas. Lands affected by drought are more vulnerable to flooding once rain falls. As temperatures rise globally, droughts will become more frequent and more severe, with potentially devastating consequences for agriculture, water supply and human health. This phenomenon has already been observed in some parts of Asia and Africa, where droughts have become longer and more intense. Hot temperatures and dry conditions also increase the likelihood of forest fires.

10 Years of Weather History in 3 Minutes NOAA El Niño: Research, Forecasts and Observations eGFI – Student Blog » Turning Air into Water Posted on December 23rd, 2011 by axb In a world increasingly affected by climate change, unexpected droughts are a harsh reality for many farmers whose livelihoods depend on regular rainfall. That’s why Edward Linacre, an industrial design graduate student from Swinburne University of Technology in Australia, decided to invent a device that can literally harvest water from thin air. Airdrop, as it’s called, recently won the prestigious James Dyson Award, which grants Linacre over $14,000 to develop the product. It was selected from among 500 entries from 18 different countries for its simple design and revolutionary approach to irrigation. The sleek, minimal design of Airdrop is in part inspired by the extraordinary water-gathering abilities of the Namib Desert Beetle, which survives in very arid climates by collecting moisture from the air with its wings. Watch Linacre explain his ingenious invention in this video: Top photo by Arsineh Houspian Filed under: e-News

Forudse vejret med skyer | Spejder.dk Hvad er skyer lavet af? Og hvordan kan man forudse vejret med dem, så du altid er beredt på næste spejderløb? Spejder.dk giver dig svaret! Bliv klogere på skyer Vi har allerede fortalt dig, hvordan du kan forudse vejret med dyr, men faktisk er skyer også blevet brugt til at forudse vejret lige siden ruderkonge var knægt. Hvad er skyer? Skyer er faktisk svævende vand. Nogle kloge typer har delt skyer ind i alle mulige forskellige kategorier, og derfor findes der 30 forskellige slags skyer. Cumulus humilis Hvis du ser Cumulus humilis skyer på himlen, kan du godt forvente lækkert og tørt vejr resten af dagen. Altocumulus perlucidus Atocumulus perlucidus skyerne kaldes også for lammeskyer. Cumulus congestus Blomskålsskyens lidt mere fornemme navn er Cumulus congestus. Cirrus Selvom cirrus-skyerne ser fine og uskyldige ud, skal du ikke lade dig narre.

La Nina Vs. El Nino October 17, 2010; 3:15 AM Sea surface temperatures play a major role in global weather and nowhere is that more evident then in El Nino and La Nina patterns. These type of patterns often lead to weather extremes, some of which can be seen in our own backyards. Sea surface temperatures indicate that we'll have a La Nina this winter, which could mean a season of weather extremes across parts of the United States. What is La Nina and El Nino? La Nina is described as cooler-than-normal sea surface temperatures in the central and eastern Pacific Ocean, near the equator off the west coast of South America. What Causes La Nina and El Nino? Simply put, easterly trade winds over the equatorial Pacific Ocean are partly to blame for both phenomenon. In an El Nino, the opposite occurs. What Does All of This Mean for the Weather? We're already seeing affects of the building La Nina. In an El Nino winter, we see what we had last season. How Long Will This All Last? Related to the Story:

NEA - Drought by Phil Nast, retired middle school teacher and freelance writer Found in: science, 3-5, 6-8, 9-12 California is the largest agricultural producing state in the country, producing 11% of the total U.S. agricultural value, and is one of the world’s most productive farming regions. Almost all almonds, olives, and walnuts grown in the United States come from the Central Valley. Yet, California is in its fifth year of drought and the resulting crop, livestock, and dairy losses will mean rising food prices for the rest of the country.
