Global warming alarmists are a clever bunch. They have very carefully changed the issue from "global warming" to "climate change." Now any change in weather, be it mild winters or cool summers can be attributed to "climate change." Whatever the weather, the news is very bad.
One claim threatens massive storms thrashing our communities. Such a threat was an easy sell in 2005 as Katrina was blamed for nearly destroying New Orleans in a hurricane season that seemed without end. Surely it could not be denied that climate change Armageddon was upon us.

The global warming debate has focused on carbon dioxide emissions, but scientists at UC Irvine have determined that a lesser-known mechanism - dirty snow - can explain one-third or more of the Arctic warming primarily attributed to greenhouse gases.
Storms strand 100s at Philly airport
Airlines canceled or delayed flights as thunderstorms rolled across the region, stranding many passengers at Philadelphia International Airport through the night, airport spokeswoman Phyllis Van Istendal said this morning.
Bad weather in Philadelphia and other cities planes were attempting to fly to or from caused hundreds of cancellations late Tuesday, and airport officials handed out disposable pillows, blankets and snacks to about 750 people who spent the night, Van Istendal said.

The National Weather Service says a moderate drought across southern Ohio is deepening, with rainfall since March 1 running 4 to 6 inches below normal south of Interstate 70.
Far southern Ohio and northern Kentucky are running seven to eight inches below normal for rainfall during that 3½-month period, according to a Weather Service report.

Heavy snows battered the Andean border region of Argentina and Chile on Wednesday, forcing the closure of a key mountain highway connecting the two countries and idling thousands of trucks.
Argentine transit officials predicted the Cristo Redentor tunnel, a nearly two-mile passage drilled into the mountains at 10,400 feet above sea level, would be impassible for 72 hours because of snowstorms and high winds, government news agency Telam reported.

At least 63 more people died on Sunday from the effects of Pakistan's record-breaking heat wave, bringing the weekend death toll to 110, news reports said on Monday.
The mercury rose as high as 52 degrees in south-west parts of the country as the hot spell entered its fourth day, also setting a 78-year record in the city of Lahore in the central Punjab province.

A powerful earthquake shook Guatemala on Wednesday, U.S. seismologists said, but there were no immediate reports of damage or injuries in the capital.
The magnitude 6.8 earthquake struck at 1:29 p.m. local time (3:29 p.m. EDT) and was centered 70 miles southwest of Guatemala City off the Pacific coast, according to the
U.S. Geological Survey (USGS).

The next time you venture into your garden armed with plants, consider who you place next to whom. It turns out that the docile garden plant isn't as passive as widely assumed, at least not with strangers. Researchers at McMaster University have found that plants get fiercely competitive when forced to share their pot with strangers of the same species, but they're accommodating when potted with their siblings.
The study appears today in the Royal Society journal Biology Letters.
"The ability to recognize and favour kin is common in animals, but this is the first time it has been shown in plants" said Susan Dudley, associate professor of biology at McMaster University in Hamilton, Canada. "When plants share their pots, they get competitive and start growing more roots, which allows them to grab water and mineral nutrients before their neighbours get them. It appears, though, that they only do this when sharing a pot with unrelated plants; when they share a pot with family they don't increase their root growth. Because differences between groups of strangers and groups of siblings only occurred when they shared a pot, the root interactions may provide a cue for kin recognition."
Though they lack cognition and memory, the study shows plants are capable of complex social behaviours such as altruism towards relatives, says Dudley. Like humans, the most interesting behaviours occur beneath the surface.

Damage from a hurricane that left five people, including an eight-year-old child, injured in Russia's Far East, has been assessed at 2.25 million rubles ($86,000), a local emergencies ministry spokesman said Wednesday.
The hurricane hit the Amur Region late Monday. Wind gusts of up to 28 meters (90 feet) per second uprooted trees, blocking roads, tore off roofs and downed transmission lines.
Over a thousand people and 125 vehicles are involved in relief operations. Some 140,000 people still remain without electricity. Power supplies are expected to be resumed later in the day, although some private households will get electricity only by the end of the week.

Cockroaches have a memory and can be taught to salivate in response to neutral stimuli in the way that Pavlov's dogs would do when the famed Russian doctor rang his bell, Japanese researchers found.
Such "conditioning" can only take place when there is memory and learning, and this salivating response had only previously been proven in humans and dogs.
Now, cockroaches appear to have that aptitude too.
Writing in the latest edition of the online journal Public Library of Science, the researchers said they hoped to learn more about the human brain by exploring what goes on in the simpler brain of the cockroach. (Article is freely available on http://www.plosone.org/doi/pone.0000529)
