  • Earth could become hotter than thought, study warns (clouds influence not correctly accounted for)

    Yahoo News ^ | 4/8/16 | AFP
    Washington (AFP) - Global warming could make the planet far hotter than currently projected because today's scientific models do not correctly account for the influence of clouds, researchers said this week. The study in the journal Science was led by researchers at Yale University and Lawrence Livermore National Laboratory. When climate scientists look ahead to how much the planet's surface temperature may warm up in response to a doubling of carbon dioxide -- a byproduct of fossil fuel burning -- they typically predict a rise of between 2.1 and 4.7 degrees Celsius (3.75 to 8.5 degrees Fahrenheit). But these models...

    An ominous “cloud tsunami” rolls in along the coast of Sydney, Australia, on Friday, signaling the coming of severe storms for the area. The massive formation, actually called a shelf cloud, stunned Australians, with a flurry of photos hitting social media. The Australian Bureau of Meteorology issued a severe thunderstorm warning for the area with possible threats of large hail storms, heavy rains and forceful winds.
  • Mystery lights in space increasing, moving south, potential sign of global warming

    Strange blue lights glowing on the edge of space first appeared over polar regions in 1885 and today, sightings are becoming increasingly common, and now the phenomenon is moving into lower latitudes including Northern California. Like the proverbial canary in the coal mine, these glowing space clouds may be a celestial siren, warning of Earth's global warming, according to some scientists. They're called "noctilucent clouds" or NLCs, basically, clouds that glow at night. They appear mainly in northern latitudes, about 50 miles above earth as miniscule droplets of water reflect the sun on the other side of the globe. Now,...

    The southern season for noctilucent clouds (NLCs) has come to an end. NASA's AIM spacecraft observed the last wisps of electric-blue over Antarctica on Feb. 20, 2015. The end of the season was no surprise: The polar clouds always subside in late summer. Looking back over the entire season, however, reveals something unexpected. In an 8-year plot of Antarctic noctilucent cloud frequencies, the 2014-2015 season is clearly different from the rest: These data come from the AIM spacecraft, which was launched in 2007 to monitor NLCs from Earth orbit. The curves show the abundance ("frequency") of the clouds vs. time...

    A phenomenal shot of a massive cloud Sunday near Clareton, Wyo., has been making the rounds on social media. The photo was taken by the Basehunters storm chasers group, who are "committed to capturing the most unique and close-up tornado footage on the market," according to their Facebook page. It shows the rotating updraft of a supercell thunderstorm over eastern Wyoming, according to Weather Channel meteorologist Jon Erdman. Supercells are the largest, strongest and longest-lasting thunderstorms. They are most common on the Great Plains. Known as a "low-precipitation" supercell, these types of storms seldom produce heavy rain or tornadoes, though...

    The storm clouds in Earth's atmosphere are filled with microbial life, according to a new study. The research, published today (Jan. 23) in the journal PLoS One, revealed that hailstones drawn from storm clouds harbor several species of bacteria that tend to reside on plants, as well as thousands of organic compounds normally found in soil. Some of the bacterial species can seed the tiny ice crystals that lead to rain, suggesting they play a role in causing rain. "Those storm clouds are quite violent phenomena," said study co-author Tina Santl Temkiv, an environmental chemist at Aarhus University in Denmark....

    LAMONT, Okla. For decades, a small group of scientific dissenters has been trying to shoot holes in the prevailing science of climate change, offering one reason after another why the outlook simply must be wrong. Over time, nearly every one of their arguments has been knocked down by accumulating evidence, and polls say 97 percent of working climate scientists now see global warming as a serious risk. Yet in recent years, the climate change skeptics have seized on one last argument that cannot be so readily dismissed. Their theory is that clouds will save us. They acknowledge that the...

    The long, feathery lines of condensation that form behind aircraft, called contrails, have more of an immediate warming effect on the Earth's surface than the carbon dioxide or other greenhouse gases that the aircraft emit, a new study calculates. However, the researchers add, contrail clouds disappear within a day or two; the potent greenhouse gas carbon dioxide lingers in the air for many years. Contrails form when the hot, moist plume of exhaust generated by an airplane's engines mixes with cold air in the upper atmosphere. Liquid droplets form and then freeze, forming a straight, white line. Over the span...

That's the surprising conclusion from a team of researchers who argue that interstellar cosmic rays collide with water molecules in our atmosphere to form overcast skies. As common as clouds are on Earth, the processes that produce them are not well understood. Scientists think particles of dust or pollen can serve as nuclei for water droplets, which in turn gather by the trillions into clouds. That would help explain how clouds form over...

    A band of intense thunderstorms moved through Oklahoma and Arkansas on the morning of June 12, 2009. This series of photographs shows how such a storm sometimes appears. Some storm spotters call this the spaceship or UFO cloud. The official name is shelf cloud. Cold air produced by heavy rain rushes out ahead of the storm; as the cooler denser air lifts the surrounding moisture, it can create this odd-looking cloud. Shelf clouds may or may not be accompanied by severe winds; but they are not tornadoes.

    Lead in the air is causing clouds in odd conditionsin conditions typically too warm and dry for cloud formationaccording to scientists who've "bottled" clouds and even grown their own. Driven mainly by industrial lead-dust emissions, lead-heavy clouds could change weather patterns and might actually help fight global warming, the study suggests. Researchers collected cloud samples atop a Swiss mountain and found that about half of their ice crystals contained lead. Then, by building artificial clouds in laboratory chambers, the team determined that lead actually causes ice crystals to form. Clouds formed in warmer, drier air when lead was present, the...

    Are those UFOs near that mountain? No -- they are multilayered lenticular clouds. Moist air forced to flow upward around mountain tops can create lenticular clouds. Water droplets condense from moist air cooled below the dew point, and clouds are opaque groups of water droplets. Waves in the air that would normally be seen horizontally can then be seen vertically, by the different levels where clouds form.

    HOBART, Australia - Some of the coldest temperatures on Earth brought a rare cloud formation to the skies over Antarctica, scientists said Tuesday. Meteorological officer Renae Baker captured spectacular images of the nacreous clouds, also known as polar stratospheric clouds, last week at Australia's Mawson station in Antarctica. The clouds only occur at high polar latitudes in winter, requiring temperatures less than minus 176 degrees Fahrenheit. A weather balloon measured temperatures at minus 189 degrees Fahrenheit on the day the photos were taken. Resembling airborne mother-of-pearl shells, the clouds are produced when fading light at sunset passes through water-ice crystals...

    Last year was the hottest on record, or the second hottest, depending on the records climatologists look at. The planet has warmed .8 degrees C over the past 150 years, and scientists are generally agreed that greenhouse gases have played a major part in that warming. They also agree that the warming will continue in the decades to come. Many experts are concerned that warming may make two unpleasant things more common: extinctions and diseases. In tomorrow's issue of Nature (link to come here), a team of scientists report on a case that ties these two dangers together: frogs have...

    Long, infrared exposures of giant gas and dust clouds reveal structures that are invisible at optical wavelengths (Image: J Foster and A Goodman, CfA) Astronomers have discovered a new way to probe dark clouds of gas and dust in space, shedding light on the mysterious conditions that nurture star birth. Stars condense from giant clouds of molecular gas and dust that float through space. But these stellar wombs are difficult to study because they are barely visible at optical wavelengths. And other methods that probe their structure are not very precise for example, estimating how much dust they...

    GAZA CITY, Gaza Strip - Israel and the Palestinians agreed on Sunday to halt their latest round of rocket attacks and airstrikes, an official said, but the deal threatened to fall through even before it was officially announced when Israeli forces killed two Islamic Jihad militants in the West Bank. Israeli forces encircled a house in the West Bank town of Qabatiyeh after sundown Sunday and killed two militants, including Jihad Zakarne, an Islamic Jihad member accused by Israel of planning a deadly suicide bombing last week, witnesses and Palestinian security officials said. The Israeli military had no comment. Islamic...

    -- A weird-looking cloud sporting the colors of the rainbow appeared to many in the Dallas-Fort Worth Metroplex early Thursday afternoon.The cloud stayed in the southeastern sky for several minutes, but was obscured by other clouds at times. NBC 5 Meteorolgist James Aydelott offered one possible explanation, saying that the sun was hitting the cloud at just the right angle, similar to a phenomenon known as "sun dogs," causing the colorful display. He also said he had never seen a cloud like this before.

    Earth's reflectivity a great unknown in gauging climate change impactsEarth's climate is being changed substantially by a buildup of atmospheric greenhouse gases, but a group of leading climate scientists contends the overall impact is not understood as well as it should be because data are too scarce on how much energy the planet reflects into space. Reflectivity, or albedo, is largely governed by clouds and atmospheric particles called aerosols, but it is one of Earth's least-understood properties, said Robert Charlson, a University of Washington atmospheric scientist. Yet research aimed at quantifying the effects of albedo and helping scientists understand how...

    SACRAMENTO (AP) - Gov. Arnold Schwarzenegger promised to wage a great battle this fall in a special election showdown with the unions, the special interests and - most of all - the Democrats. But with his numbers falling in the polls and a key petition deadline approaching, there is growing uncertainty not only about which measures voters might face but even whether Schwarzenegger still wants the confrontation.
