“Most of what you learn won’t be in a classroom or out of a book” my father told me 40 years ago. “You learn from your mistakes” he said. He was right. It’s a painful learning curve, and it applies to most fields.
The atmosphere is a fluid; calculus predicts how parcels of air should behave, but the math isn’t perfect. Neither is our digital snapshot of current weather, worldwide. We have good data over North America, Europe & Asia, but satellites fill in the blanks over much of the planet. Junk in – junk out. That’s why the 7-Day accuracy is still sketchy.
We’re drowning in weather models; hundreds to choose from. What to believe, and when?
That’s why weather forecasting is still as much art as science. Bad art. Finger painting in the dark, some days.
All the models show seasonable warmth much of this week, with colder air returning next weekend – the atmosphere cold enough for snow by mid-November. But will there be any moisture? The pattern favors big storms on either coast; a cool, dry northwest flow aloft over Minnesota. Rain showers drift into town Monday, again Wednesday.
The first snow flurries of winter may be about 7-10 days away, about 3 weeks later than average.
Warmest UK Halloween On Record. Britain’s BBC has the story – here’s a clip: “…A temperature of 23.5C (74.3F) was recorded in Gravesend, Kent, surpassing the previous record of 20.0C. Other parts of the south of England and the north coasts of Wales and Norfolk also broke the 20C mark. The previous record was set in Dartford, Kent, in 1968 and was matched in north-eastern parts of Greater London in 1989…”

These Maps of California’s Water Shortage are Terrifying. Mother Jones has the story – here’s an excerpt: “…The maps come from a new paper in Nature Climate Change by NASA water scientist James Famiglietti. “California’s Sacramento and San Joaquin river basins have lost roughly 15 cubic kilometers of total water per year since 2011,” he writes. That’s “more water than all 38 million Californians use for domestic and municipal supplies annually—over half of which is due to groundwater pumping in the Central Valley.” Famiglietti uses satellite data to measure how much water people are sucking out of the globe’s aquifers, and summarized his research in his new paper…”

Think Progress has a slightly different perspective on groundwater aquifer depletion here.
Why The U.S. Has Fallen Behind In Internet Speed and Affordability. Where are the broadband disruptors? Because, according to this article at The New York Times, America’s internet providers are providing substandard speeds at inflated prices; here’s an excerpt: “…Downloading a high-definition movie takes about seven seconds in Seoul, Hong Kong, Tokyo, Zurich, Bucharest and Paris, and people pay as little as $30 a month for that connection. In Los Angeles, New York and Washington, downloading the same movie takes 1.4 minutes for people with the fastest Internet available, and they pay $300 a month for the privilege, according to The Cost of Connectivity, a report published Thursday by the New America Foundation’s Open Technology Institute…”
How Iowa Scientists Are Fighting To Get Climate Change on the Political Radar. Think Progress has the story – here’s the introduction: “A little less than three weeks ago, over 180 Iowa scientists sent a clear message to their state’s leaders: climate change is here, is impacting Iowans and needs to be taken seriously. The Iowa Climate Statement 2014: Impacts on the Health of Iowans was the fourth iteration of an annual effort by the Iowans who actually study climate change to raise awareness among their fellow residents, their state lawmakers and their national representatives…”
Hagel: “Climate Change Presents Security Issues” for U.S. TheHill has the story – here’s an excerpt: “…When asked if people would be more responsive to climate science because the military is, Hagel agreed that the Pentagon is taken more seriously, and its work on climate change would likely be received well. “There is more of an awareness and an edge put on an issue when it comes to the Pentagon,” Hagel said. “Because the military and Pentagon has maybe — at least perceived by other people — a more serious look at the world.”
The Weather Channel’s Climate Challenge. Now anyone with a computer (or window) can pretend to be a climate scientist! Founder and meteorologist John Coleman still believes that climate change is a hoax. The channel he helped to launch respectfully disagrees. Here’s a clip from The Atlantic: “…John Coleman, a retired television meteorologist and founder of The Weather Channel, appeared on Fox News on Monday and claimed that he does not believe in climate change. “Well, there are 9,000 Ph.D.s and 31 scientists who have signed a petition that says [carbon dioxide] is not a significant greenhouse gas. Oh it’s a teeny, itsy-bitsy greenhouse gas, but it’s not in any way significant,” said Coleman. “And we are sure of it. It’s not like something I just made up or just thought of. I’ve studied and studied and studied...”

Climate Change Impacts on NASA Facilities. Here’s an excerpt from a report released by NASA: “The impacts of a changing climate are affecting NASA’s properties and operations. In response, NASA is implementing policy addressing climate change adaptation: Apply NASA’s scientific expertise and products to incorporate climate information into its decision making and planning; create innovative, sustainable, and flexible solutions; and share best practices, in order to create climate-resilient NASA Centers…”
