As drought continues, South Florida's water restrictions to tighten

Even with the vast Atlantic Ocean lapping at its shores and more yearly rainfall than most of the country, South Florida once again finds itself wanting for water.

South Florida typically gets 52 inches of rain a year -- 14 inches more than soggy Seattle -- but doesn't have the storage capacity to capture enough water to quench the thirst of a growing population.

Comment: A simple solution utilized in many other tropical areas, and formerly a standard feature in old Florida, is for each home to have a cistern that captures rainwater for bathing and watering plants.

Los Angeles suffers longest dry spell in 130 years

Los Angeles is going through its longest dry spell in at least 130 years, the National Weather Service said Sunday, fueling fears of rampant wildfires which have plagued the US west coast in recent years.

"The rain season is currently the driest to date in downtown Los Angeles since records began in 1877," the weather service said in a statement.

NBC, Reuters, AFP Reports: 8.0 Earthquake Triggers Tsunami in Solomons - Whole villages 'wiped out'

UPDATE: Quake upgraded to 8.0

HONIARA, Solomon Islands - A powerful magnitude-7.6 earthquake struck off the Solomon Islands on Monday, sending a tsunami wave crashing into the country's west coast and prompting region-wide disaster warnings, officials said.

Sgt. Godfrey Abiah said police in the capital, Honiara, reported a wave several yards high had crashed ashore in the western town of Gizo shortly before communication lines with the region were cut.

Alarming Decline of Sharks Causing Other Species to Vanish

The precipitous decline in large predator sharks in the Atlantic Ocean in the past decade has made ecologists worry about a trickle-down effect on the ocean ecosystem.

A new study supports the case. With the large predators gone, their prey - smaller sharks and rays - are free to feast on lower organisms like scallops and clams, depleting valuable commercial stocks.

Flowers and fruit crops facing disaster as disease kills off bees

Devastating diseases are killing off vast numbers of bees across the country, threatening major ecological and economic problems. Honeybee colonies have been wiped out this winter at twice the usual rate or worse in some areas.

Argentina Floods Claim 7 Lives

BUENOS AIRES, Argentina - Rising rivers in three rain-soaked provinces have forced some 38,000 people to flee their homes and floodwaters have claimed seven lives, authorities said Saturday.

Abrupt climate change more common than believed

It came on quickly and then lasted nearly two decades, eventually killing more than one million people and affecting 50 million more. All of this makes the Sahel drought, which first struck West Africa in the late 1960s, the most notorious example of an abrupt climatic shift during the last century.

Dramatic as this single event was, University of Wisconsin-Madison researchers have now uncovered 29 other regions worldwide that endured similarly precipitous climatic changes during the 20th century - far more than scientists previously thought. Their study publishes today (March 30) in the online edition of Geophysical Research Letters.

Measuring Changes In Arctic Sea Ice

Arctic sea ice is in constant motion. It rides on the ocean, absorbing energy from the circumpolar weather systems.

This movement causes a buildup of stress within the ice. Under enough stress, the ice cracks or buckles in a cataclysmic process that resembles the energy released in earthquakes. These continuous ice quakes result in open leads of water or mountainous ridges of broken, jumbled ice. These deformations, in turn, may have an effect on the thickness and durability of the arctic ice pack in the face of climate change.

University of Alaska Fairbanks researcher Jennifer Hutchings hopes that a better understanding of this complex process will help improve climate models and shed light on how sea ice behaved in the past and how it may change in the future.

Tornadoes are Earth's most violent storms

Tornadoes are the most violent storms on Earth. Winds spiraling into them usually exceed 100 mph and can reach speeds of 300 mph. In the USA, an average of 1,000 tornadoes spin up beneath thunderstorms each year, and these typically kill about 60 people.

Tornadoes and the threat of tornadoes are a key part of the USA's spring weather because spring brings favorable tornado conditions. But tornadoes can occur any time of the year, during the day and at night.

65 Tornadoes - One As Wide as Two Football Fields - Kills 4 in 3 States

An F2 tornado roars near Seymour, Texas, in April 1979. F2 and F3 tornadoes are considered strong, packing winds of 113-206 mph that can cause major to severe damage.

OKLAHOMA CITY - A tornado as wide as two football fields carved a devastating path through an eastern Colorado town as a massive spring storm swept from the Rockies into the Plains, killing at least four people in three states, authorities said Thursday.

Sixty-five tornadoes were reported in Oklahoma, Texas, Kansas, Colorado and Nebraska on Wednesday, the National Weather Service said.
