From The Daily Mail:

When Britain woke up on the first day of the New Year it was met with freezing cold temperatures, feet of snow in places and the promise of travel chaos.

And now, three days into 2010, forecasters have warned to expect continued snowfall for the next 10 days - bringing with it added stress for commuters heading back to work after a festive break and children returning to school tomorrow.

Global Warming ALERT: British Experts Predicting Coldest Winter In 100 Years


From YID With LID:

Word to the British, you better buy a new winter coat. Experts are predicting that this will be one of the coldest winters in the past 100 years. This kind of weather was predicted by scientist, Mojib Latif who back in September predicted that earth was going to cool off for the next 20-30 years. Latif said the cooling would be the result of changes to ocean currents and temperatures in the North Atlantic, a feature known as the North Atlantic Oscillation (NAO) and the NAO may be partly the cause of warming during the past 30 years.

Its ironic that in Britain, home of the Climate Research Unit of the University of East Anglia, recently made famous by the climategate is facing one of the coldest winters in 100 years, experts predict temperatures hitting minus 16 degrees Celsius (+3 Fahrenheit).

Britain Facing One Of The Coldest Winters In 100 Years, Experts Predict

Parts of Scotland have had snowcover for nearly three weeks

From The Telegraph:

Britain is bracing itself for one of the coldest winters for a century with temperatures hitting minus 16 degrees Celsius, forecasters have warned.

They predicted no let up in the freezing snap until at least mid-January, with snow, ice and severe frosts dominating.

And the likelihood is that the second half of the month will be even colder.

Russia Reigns Over Its Weather

Snow may be an icon of Russian winters, but city officials in Moscow say it's too expensive to clear. They're considering a cloud-seeding process that would prevent heavy snowfalls in the capital. (Sergei L. Loiko / Los Angeles Times / December 8, 2009)

From The L.A. Times:

Moscow officials have already chased away clouds on public holidays. Now they're considering cloud seeding to keep snow-removal costs down in the winter. Neighboring towns may get dumped on.

Reporting from Moscow - In the snow-hushed woods on Moscow's northern edge, scientists are decades deep into research on bending the weather to their will. They've been at it since Soviet dictator Josef Stalin paused long enough in the throes of World War II to found an observatory dedicated to tampering with climatic inconveniences.

From Live Science:

One of the dramatic and often unseen effects of tropical storms and hurricanes is the muck they churn up from the ocean floor as they come ashore.

These clouds of sediment in the Gulf of Mexico were spotted Nov. 10, after Tropical Storm Ida made landfall and then moved on.

The image was made from data collected by NASA’s Aqua satellite.

October USA – Temperature 3rd Coldest On Record, Wettest Ever On Record

From Watts Up With That?

Temperature Highlights – October

* The average October temperature of 50.8°F was 4.0°F below the 20th Century average and ranked as the 3rd coolest based on preliminary data.
* For the nation as a whole, it was the third coolest October on record. The month was marked by an active weather pattern that reinforced unseasonably cold air behind a series of cold fronts. Temperatures were below normal in eight of the nation’s nine climate regions, and of the nine, five were much below normal. Only the Southeast climate region had near normal temperatures for October.

October 2009 3rd Coldest for US In 115 Years, What About The Upcoming Winter?



From Watts Up With That?:

NCDC has compiled the October temperatures and it ended up the 3rd coldest in 115 years. As we have shown it was cold over almost all the lower 48. Indeed only Florida came in above normal. There is no [NOAA/NCDC] press release out yet but it should be interesting.

Can We Really Control The Weather?

Cloud-seeding is a controversial practice common in Russia and China. Getty

From The Independent:

Recently both Russia and China have claimed to be able to use cloud seeding to increase rainfall and snowfall, or change the location of where it falls. In the past, snow-making experiments have been carried out in North American ski resorts in the past with little evidence of success. So how have the Russian and Chinese scientists achieved this feat and what evidence is there that it is in fact due to cloud seeding?

Can We Manipulate The Weather?

From The Guardian:

Chinese scientists claim to be able to control the weather. But is so-called geoengineering more than wishful thinking? And, if so, should we be worried?


The unseasonal snow that fell on Beijing for 11 hours on Sunday was the earliest and heaviest there has been for years. It was also, China claims, man-made. By the end of last month, farmland in the already dry north of China was suffering badly due to drought. So on Saturday night China's meteorologists fired 186 explosive rockets loaded with chemicals to "seed" clouds and encourage snow to fall. "We won't miss any opportunity of artificial precipitation since Beijing is suffering from a lingering drought," Zhang Qiang, head of the Beijing Weather Modification Office, told state media.

From Live Science:

This summer, the Verification of the Origins of Rotation in Tornadoes EXperiment 2 (VORTEX2) brought 80 scientists and crew members and dozens of research vehicles and platforms to the tornado-prone regions of the United States to conduct the most detailed studies to date of tornadoes. Sarah Dillingham was part of that effort, one of the members of Texas Tech’s Multiple Observations of Boundaries In the Local storm Environment (MOBILE) team, helping deploy StickNet mobile sensors in the paths of dangerous storms. VORTEX2 has wound down for the 2009 season, but will re-emerge in 2010. Dillingham offers her thoughts on her first yield of field research as she responds to the ScienceLives 10 Questions below.

Weird, Rare Clouds And The Physics Behind Them


From Wired Science:

In August, we posted a photograph of some odd, rare clouds known as Morning Glory clouds without providing an explanation for how they form. In response to reader interest, we followed up with meteorologist Roger Smith of the University of Munich, who has studied their formation.

“Over the years we’ve developed a good understanding of them,” Smith said. “It’s no longer a mystery, but still very spectacular.”

Supertyphoons To Strike Japan DueTo Global Warming

Supertyphoon Sepat bears down on the Philippines in the Pacific Ocean on August 15, 2007. Increasingly powerful storms will devastate countries in the western Pacific Ocean, including Japan, as rising temperatures add fuel to storms, scientists said in September 2009. Photograph by NOAA/AP

From National Geographic:

Increasingly powerful "supertyphoons" will strike Japan if global warming continues to affect weather patterns in the western Pacific Ocean, scientists say.

Supercomputer simulations show there will be more typhoons with winds of 179 miles (288 kilometers) per hour—considered an F3 on the five-level Fujita Scale—by 2074.

The Australian Dust Storm As Seen From Space – Dry lake Eyre Not Global Warming?


From Watts Up With That?

There’s been quite a bit of buzz about the dust storm in Australia that hit Queensland, New South Wales, and NSW city Sydney on September 23rd. Pictures like the ones below have been all over the web.

But it is the photos taken from space that are the most interesting I think. NASA’s Earth Observatory captured a truly amazing photo that shows the dust storm front as it swept across the continent and headed out to sea over eastern Australia where the borders of Queensland and NSW meet.

Why Autumn Begins Tuesday


From Live Science:

The first day of autumn — Sept. 22 this year — is no guarantee of fall-like weather, but officially the season's start comes around at the same time each year nonetheless.

Well, sort of.

The first day of autumn arrives on varying dates in different years for two reasons: Our year is not exactly an even number of days; and Earth's slightly noncircular orbit, plus the gravitational tug of the other planets, constantly changes our planet's orientation to the sun from year to year.

It's Raining Less Than Scientists Thought


From Live Science:

Raindrops just broke their own speed record: they can drop faster than anyone thought possible.

Larger drops are speedier than smaller ones because they are heavier and so can more easily overcome air resistance. But there’s a limit to how fast a drop can go, a “terminal velocity” achieved when the downward force of gravity equals the upward drag of the air. Thus, whenever smaller drops are detected apparently beating larger ones in the race to the ground, atmospheric scientists interpret the observations as errors by recording instruments.

Wolff (Space Science Inst.), Hubble Heritage Team (STScI / AURA), NASA

From Live Science:

Maybe even more than average citizens, the world's space agencies rely on daily and seasonal reports to better understand weather on Earth and other planets. Space-mission success ties directly to effective anticipation and navigation of inclement surface and atmospheric conditions.

Mission-design engineers at NASA, the European Space Agency (ESA), and similar organizations need to know what environmental issues a Mars Lander or Rover might face to ensure that heat shields, parachutes and other on-board mechanisms survive the trip through the atmosphere to the surface.

Can Geoengineering Help Slow Global Warming?


From Time Magazine:

As we pump billions of tons of carbon dioxide into the atmosphere, we're doing more than warming the planet and scrambling the climate. We're also conducting what climatologist James Hansen has called a "vast uncontrolled experiment." In effect, we're on our way to engineering a world very different from the one we were handed. Belatedly, we're trying to turn off the carbon spigot, hoping that by incrementally reducing the emissions we've spent a couple of centuries pouring into the air we can stop the climate slide before it's too late.

Big Tropical Storms in Atlantic Hit 1,000-Year High


From ABC News:

Study Suggests Hurricane Frequency Has Increased Dramatically; Climate Change a Potential Culprit.

The people of U.S. Gulf Coast have felt unusually battered by big storms during the past few years. Now, it turns out their instincts are right.

A new report in the scientific journal Nature indicates that the last decade has seen, on average, more frequent hurricanes than any time in the last 1,000 years. The last period of similar activity occurred during the Medieval Warm Period.

The study is not definitive, but it is a unique piece of work that combines an analysis of sediment cores from inland lakes and tidal marshes with computer modeling and finds a "striking consistency" between the two, the authors suggest.

Earth's Most Prominent Rainfall Feature Creeping Northward

From Science Daily:

ScienceDaily (Aug. 9, 2009) — The rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years, probably because of a warmer world, according to research published in the July issue of Nature Geoscience.

If the band continues to migrate at just less than a mile (1.4 kilometers) a year, which is the average for all the years it has been moving north, then some Pacific islands near the equator – even those that currently enjoy abundant rainfall – may be drier within decades and starved of freshwater by midcentury or sooner. The prospect of additional warming because of greenhouse gases means that situation could happen even sooner.
