Not just here, where we're looking forward to 10°C on New Year's Eve to complete a streak of 21 days above normal temperatures,, but also Northern Europe:
Britons getting ready to ring in 2012 can expect highs of up to 15°C after a year of unusually mild weather.
Forecasters said the past 12 months have been the second warmest for the UK after 2006, in which the average temperature reached
9.73°C. The average for 2011 was just a shade lower at
9.62°C.
It comes after the warmest April and spring on record, the second warmest autumn and the warmest October day.
The U.K. also had its warmest temperature in five years on June 27th, when Gravesend, Kent, hit
33.1°C. Pretty soon Britons will need air conditioners.
But there's no anthropogenic climate change happening. None at all.
There is no tomorrow for the island nations of Samoa and Tokelau:
At the stroke of midnight on Dec. 29, time in Samoa and Tokelau will leap forward to Dec. 31 — New Year's Eve. For Samoa's 186,000 citizens, and the 1,500 in Tokelau, Friday, Dec. 30, 2011, will simply cease to exist.
[Samoan] Prime Minister Tuila'epa Sailele Malielegaoi earlier said it would strengthen trade and economic links with Australia, New Zealand and Asia.
Being a day behind the region has meant that when it's dawn Sunday in Samoa, it's already dawn Monday in adjacent Tonga and nearly dawn Monday in nearby New Zealand, Australia and increasingly prominent east Asian trade partners such as China.
"In doing business with New Zealand and Australia, we're losing out on two working days a week," Tuila'epa said in a statement. "While it's Friday here, it's Saturday in New Zealand, and when we're at church on Sunday, they're already conducting business in Sydney and Brisbane."
The islands move from UTC-10:00 to UTC+14:00, and will therefore be the first places on earth to enter 2012.
Even though we still have two weeks to go, 2011 has already experienced the costliest year of weather disasters in decades:
From extreme drought, heat waves and floods to unprecedented tornado outbreaks, hurricanes, wildfires and winter storms, a record 12 weather and climate disasters in 2011 each caused $1 billion or more in damages — and most regrettably, loss of human lives and property.
The Illinois State Climatologist adds:
We also experienced some $50 billion in total losses for the year. And that is with a fairly quiet hurricane season. Some of those billion dollar disasters had direct impacts on Illinois, including the February blizzard, and the spring flooding.
NOAA has art:

We finally got our first measurable snowfall of the 2011-12 winter:
It's official. We got our first measurable snow early this morning. O'Hare reported 13 mm of fresh snow. 2011 now ties 1948 as the year with the 5th latest first measurable snow for a winter season. We now join more than a third of the country with snow cover. The National Snow Analysis from the National Operational Hydrologic Remote Sensing Center reports that as of yesterday, 37.3% of the US had snow cover with an average depth of 45 mm.
I like how almost all of Illinois is snow-free, except for that tiny bit around Chicago. Hm. Anyway, it looks like La Niña is doing its thing this year, so we will probably have a warmer, wetter winter than usual. As long as it doesn't look like this.
Finally. In Chicago, anyway. The farther north you go, the more likely your latest sunset is...earlier.
I explained why this happens December 8th a few years ago. And yet, I feel the need to comment on it yet again...
Chicago might get measurable snowfall tonight, which would be the fourth-latest first fall in history and the first since April 18th:
Though flurries have been observed within the city limits four times this month and seven times since the snow season began this year on Nov. 9, the only "measurable snow" which has fallen has been across the northern suburbs.
That may change as a light-snow-generating disturbance swings across the metro area Thursday night. The system's approach will become more and more evident Thursday as sunshine is filtered by an influx of clouds out ahead of the disturbance's light snow, particularly Thursday afternoon and evening.
But:
If there's a snowstorm in Chicago's future the next two weeks, there is NO computer model consensus on it at this point. That can change fairly quickly this time of year. But for now, Thursday night's wave of light snowfall is the only definitive snow threat the metro area faces in the short term.
I had planned to visit the Tokyo National Museum today, and possibly one of the other museums at Ueno Park, but then this happened:
Yes, a sunny autumn day with the temperature passing 21°C simply did not allow me to go inside. I spent a few hours just walking around Ueno-Koen, encountering the local fauna:
More fauna:
Oh, and hey, my camera shoots video:
(Apologies for the jerkiness; I was hand-holding a 250mm lens.)
Via the Chicago Tribune, NASA launched a new weather satellite in October that provides incredible high-resolution images of the planet:
VIIRS will collect radiometric imagery in visible and infrared wavelengths of the Earth's land, atmosphere, and oceans. By far the largest instrument onboard NPP, VIIRS weighs about 556 pounds (252 kilograms). Its data, collected from 22 channels across the electromagnetic spectrum, will be used to observe the Earth's surface including fires, ice, ocean color, vegetation, clouds, and land and sea surface temperatures.
During NPP's five-year life, the mission will extend more than 30 key long-term datasets that include measurements of the atmosphere, land and oceans. NASA has been tracking many of these properties for decades. NPP will continue measurements of land surface vegetation, sea surface temperature, and atmospheric ozone that began more than 25 years ago.
NASA has more information about the satellite mission and a gorgeous photo (8MB jpeg) of the East Coast.
My weather demo, Weather Now, is 13 years old today. I launched it as an ASP 2.0 application on 11 November 1998.
