Flooding forces Kansas town's evacuation

Even after sunshine returned to southeast Kansas and southwest Missouri, rivers swollen by days of heavy rain inched dangerously upward across the Plains.

The Marais Des Cygnes River flows over the U.S. 59 bridge in Ottawa, Kan., Sunday, July 1, 2007. Closed flood gates protect the downtown business district. Flooding worsened across southeast Kansas and southwest Missouri Sunday as high water levels forced more people from their homes and forecasters said it could be days before area rivers begin returning to normal. Among the hardest hit regions was Osawatomie, Kan., in Miami County, where the Kansas National Guard was deployed to help with a mandatory evacuation of the city as workers struggled to reinforce a levee on the Marais des Cygne.

It's not just the UK - weird weather is worldwide!

This year is on track to be the world's second warmest on record, experts warned yesterday.

The heavy flooding here this week and the heatwave in Greece may herald even greater disruptions from global warming, they said.

Their comments came as the European Commission advised leaders to 'adapt or die' in the face of climate change.

Alarmist global warming claims melt under scientific scrutiny

In his new book, The Assault on Reason, Al Gore pleads, "We must stop tolerating the rejection and distortion of science. We must insist on an end to the cynical use of pseudo-studies known to be false for the purpose of intentionally clouding the public's ability to discern the truth." Gore repeatedly asks that science and reason displace cynical political posturing as the central focus of public discourse.

Update! Floods follow drought in eastern Australia, worst in 40 years

Residents of a previously drought-stricken area of southeastern Australian were Friday being evacuated to safety as rising floodwaters threatened to swamp homes and farmland.

Scores of people have already been evacuated by army helicopters and police from homes in Gippsland in the east of Victoria state as officials warned that the deluge could worsen as rivers peak.

Jeff Amos, deputy mayor of the Wellington Shire Council, said it was ironic that residents who had recently battled savage bushfires and a long-standing drought had been confronted almost overnight with a flood emergency.

"It was a fair deluge during the past week which has put an end to the drought in one way," Amos told AFP. "But unfortunately it's probably going to do more damage than good.

Coral Reef Fish Starve Themselves to Maintain Social Order

Some coral reef fish starve themselves to avoid getting into fights with their larger, dominant neighbors, researchers have found.

Emerald coral gobies live in small groups in which social rank is strictly determined by body size. Within each group only the largest, dominant female mates with the one resident male.

Rather than competing for the top spot, subordinate female gobies often limit their own growth to remain non-threatening to higher-ranking fish.

Underlying this strategy of peaceful coexistence is fear of being kicked out and left to die, the researchers say.

Each goby group of up to 17 individuals occupies a single coral colony that provides food and shelter.

"Night-shining" clouds bring mystery; Once confined to Earth's poles, the bizarre clouds have now been spotted above central Colorado

Since their discovery 120 years ago, strangely luminescent clouds called noctilucent clouds have been creeping slowly toward the equator.

This hauntingly beautiful noctilucent cloud was photographed over the Juneau, Alaska, ice field in 1998. Once confined to Earth's poles, the clouds have been spotted above Colorado.

A mystery: NASA satellite captures first view of 'night-shining' clouds

A NASA satellite has captured the first occurrence this summer of mysterious iridescent polar clouds that form 50 miles above Earth's surface.

The first observations of these clouds by the Aeronomy of Ice in the Mesosphere (AIM) satellite occurred above 70 degrees north on May 25. Observers on the ground began seeing the clouds on June 6 over northern Europe. AIM is the first satellite mission dedicated to the study of these unusual clouds.

These mystifying clouds are called Polar Mesospheric Clouds, or PMCs, when they are viewed from space and referred to as "night-shining" clouds, or noctilucent clouds, when viewed by observers on Earth. The clouds form during the Northern Hemisphere's summer season that begins in mid-May and extends through the end of August. They are being seen by AIM's instruments more frequently as the season progresses. The clouds also are seen in the high latitudes of the Southern Hemisphere during the summer months.

Very little is known about how these clouds form over the poles, why they are being seen more frequently and at lower latitudes than ever before, or why they have been growing brighter. AIM will observe two complete polar mesospheric cloud seasons over both poles, documenting for the first time the entire, complex life cycle of PMCs.

Comment: The article starts out by assuming it's a change in the atmosphere that's creating the clouds, but then later on says, "The Cosmic Dust Experiment is recording the amount of space dust that enters Earth's atmosphere to help scientists assess the role this dust plays in PMC formation." So which is it? Could the dust be a pre-swarm indicator?

If so, the dust would have to come from particles big enough not to be blasted out by the solar wind, implying that small meteors are responsible which would explain the increasing number of fireballs seen worldwide in the past few years. It's all speculation, but the point is not to assume that it's an atmospheric change only.
