Another Early Spring Brings Back Memories of 2012
The decorative, cosmetic splashes of snow in your yard are in grave peril. Snap a photo soon, because another warm front is coming. This winter, when in doubt, predict a warm front. Odds are you'll be right.
Then again, data shows February was the 18th month/row of warmer than average temperatures, according to the Minnesota DNR. NOAA reports that meteorological winter was the 8th warmest on record.
Nationwide there were 3,146 record highs and 27 record lows last month. Chicago had no snow on the ground in January and February. Spring is in full bloom south of a line from Kansas City to Indianapolis and Pittsburgh.
Yes, odds favor an early ice-out and at the rate we're going we may see flowers blooming within a month, much like we saw in 2012.
Today and Friday will be cooler than average but a weekend thaw is on tap. ECMWF (European) guidance hints at 60F Sunday & Monday. Another warm front surges north late next week and T-storms may pop up 1 week from today.
It's hard not to cheer on these amazing early springs - until you realize the planet is running a low-grade fever.
Early Bird Special: Spring Pops Up Super-Early in Much of U.S. Here's an update from AP: "Spring has sprung early — potentially record early — in much of the United States, bringing celebrations of shorts weather mixed with unease about a climate gone askew. Crocuses, tulips and other plants are popping up earlier than usual from Arizona to New Jersey and down to Florida. Washington is dotted with premature pink blossoming trees. Grackles, red-winged blackbirds and woodpeckers are just plain early birds this year. The unseasonably warm weather has the natural world getting ahead of — even defying — the calendar, scientists said Tuesday. In cities like Indianapolis, Pittsburgh and Columbus, Ohio, spring has arrived about a month earlier than the 30-year average and about 20 days earlier than in 2012, which was the earliest spring on record..."

Phased-Array Radar Could Improve Tornado Prediction Times. IEEE Spectrum has a good backgrounder piece on the benefits of phased-array; the U.S. Navy has been using it to track missiles - it only makes sense to see a trickle-down from military to the consumer sector: "...A phased-array radar can capture the scene much more quickly. This type of radar system features a fixed, flat antenna composed of thousands of transceiver elements sending and receiving pulses at the same time. The relative delays between the pulses shape the direction of the beam radiating from the array. This electronically steered beam can scan the whole sky in less than a minute. Forecasters would also be able to instantly redirect it to focus on specific areas. "It gives forecasters information almost like a movie, as opposed to taking snapshots of the atmosphere," says Doug Forsyth, who leads radar research at the NSSL. U.S. Navy ships have used phased-array radars for decades to detect missile threats. In fact, since 2003, the NSSL has been testing an antenna donated by the Navy. A group of National Weather Service forecasters are invited to participate in the trials, which include yearly mock tests on real tornado data..."

Have We Underestimated the West's Super-Floods? This winter is redefining wet for California and the entire west coast of the USA, but it pales in comparison to previous deluges. Here's an excerpt from High Country News: "...In California, too, super-floods may be more common than previously thought. United States Geological Survey hydrologist Michael Dettinger and UC Berkeley paleoclimatologist B. Lynn Ingram have studied the paleo-flood record across a broad swath of California and discovered that such floods happen at least every 200 years, and maybe more frequently. The last one was in 1862. Thousands of people died, towns were submerged and the state’s economy was devastated, yet it was nowhere near the worst: One flood in the 1600s was at least twice as big..."
Global climate change is being felt in many coastal communities of the United States, not always in the form of big weather disasters but as a drip, drip, drip of nuisance flooding. According to researchers at the University of California, Irvine, rising sea levels will cause these smaller events to become increasingly frequent in the future, and the cumulative effect will become comparable to extreme events such as Hurricane Katrina or Superstorm Sandy. “Catastrophic storms get a lot of media attention and are studied, but we wanted to know more about the non-extreme events,” said Amir AghaKouchak, associate professor of civil and environmental engineering at the University of California Irvine (UCI) and co-author of a new study on cumulative hazards in Earth’s Future, a journal of the American Geophysical Union..."

Trump to Put Obama Water Pollution Rule on Chopping Block. A case of over-regulation; federal over-reach? Here's more perspective from Bloomberg: "...In imposing the Waters of the U.S. rule, the Obama administration’s EPA aimed to resolve decades of uncertainty over what waterways were subject to federal regulation and oversight. In 2006, the U.S. Supreme Court fractured over the question of whether strictly navigable waters are subject to the Clean Water Act, or if the jurisdiction goes further. Developers said later guidance from the EPA only injected more confusion into permitting processes. Obama’s Waters of the U.S. rule was opposed by dozens of states and an assortment of business and agriculture groups, which complained it did nothing to clear up the murkiness and took an overly expansive view of the law..."

6 Words That Could Go Extinct Because of Climate Change. Outside Magazine reports: Lift Line. Noun: The queue of skiers and snowboarders waiting to board a chairlift for a ride up the mountain at a winter resort. This winter, ski resorts have seen record-breaking storms and crowds. So climate threats must be a Cascadian hoax, right? No. Though colder and warmer winters are determined mainly by fickle jet streams, global warming has contributed to an increased number of “End of Days” storms over the past half-century. The average global temperature has risen 1.5 degrees Fahrenheit since 1880: warmer weather means more moisture in the air, which means more intense precipitation events. At lower elevations, another two-degree temperature increase has the potential to turn all that fresh powder into floods and landslides. And you may have noticed this winter that the season is getting shorter. While there might be a few epic days in the middle of winter, there’s less time on either end of winter..."

What is Wrong With a Carbon Tax? The author of a Scientific American Op-Ed (who happens to be an economist) argues for a cap and dividend approach, instead of tax and dividend: "...The upshot is that a carbon tax is not only a nonstarter in terms of good political optics, but also in terms of good economics, ethics and science. That said, while the CLC should ditch the tax, the public dividend component of their plan is worth keeping. As they convincingly argue, the dividend is a brilliant way to overcome political resistance to a carbon fee by giving every American with a social security number an immediate economic stake in the program. For example, the CLC estimates that at their suggested $40/ton level, “a family of four would receive approximately $2000 in carbon dividend payments in their first year.” As with social security, payouts would go to rich and poor alike, thus generating sufficient popularity to protect the program against shifting political winds..."
