Mild Bias Into Mid-November Eastern USA

2 Nov 2013, 6:27 am


Canadian Infiltration. Nothing arctic is brewing (yet), but after a balmy Friday New England and the Mid Atlantic states chill down today, while temperatures moderate slightly over the Great Lakes and Upper Midwest, the western USA still trending chillier than average. The solid red line denotes the 32F isotherm. 12km NAM forecast 2-meter temperatures into Monday night courtesy of NOAA and Ham Weather.


Mild Bias Into Mid-November. The North Atlantic Oscillation (NAO) is trending milder than average looking out 10-12 days, suggesting average or slightly milder than average temperatures through much of the second week of November. Graph: NOAA.


NAEFS Model. Alaska has been unusually warm since October, and that unusually warm bias continues from Alaska into Canada’s Arctic region, with a (slight) mild bias from the Great Lakes into the Southeast, while the west trends cooler between November 9-15.


Just For Laughs And Giggles. Here is predicted snowcover for the USA through December 11, based on NOAA NCEP’s CFS (Climate Forecast System). I know, it’s interesting to look at, but I’m not (yet) convinced there’s any skill here. It shows significant snow reaching the upper Midwest by November 13-14. I’m skeptical but suspending my disbelief until I see a few more runs (looking for some level of continuity from run to run). Confidence level: 1 (on a scale of 1 to 10).

When Will We Hit Peak Garbage? has an interesting read – here’s the introduction: “In 2013, if you’re someone who cares about the environment, your first and foremost concern is probably climate change. After that, you might worry about things like radioactive contamination, collapsing honeybee colonies and endangered ecosystems, among other contemporary environmental perils that fill recent news headlines. But a number of researchers in the field are focused on a problem that has faded out of the news cycle: the piles of garbage that are growing around the world. A recent World Bank report projected that the amount of solid waste generated globally will nearly double by the year 2025, going from 3.5 million tons to 6 million tons per day. But the truly concerning part is that these figures will only keep growing for the foreseeable future. We likely won’t hit peak garbage—the moment when our global trash production hits its highest rate, then levels off—until sometime after the year 2100, the projection indicates, when we produce 11 million tons of trash per day…”

Japan’s “Toxic” Monster Creeping Towards U.S. Speaking of garbage – debris from Japan’s massive tsunami in 2011 is pushing across the Pacific, as reported by Fox News; here’s the intro: “An enormous debris field is creeping toward the U.S. in the wake of the massive earthquake and tsunami that shook Japan in 2011, killing nearly 16,000 people and launching 1.5 million tons of floating objects into the sea. That most concentrated part of the junk field is easily broader than Texas and centered approximately 1,700 miles off the Pacific coast, between California and Hawaii, although the National Oceanic and Atmospheric Administration (NOAA) hasn’t published more precise estimates. The agency estimates that the trash overall is scattered across an area in the ocean about three times the size of the continental United States…”



Hold The Spice Please. I hope you’re not eating as you read this story from Quartz; here’s an excerpt: “If you use everyday spices such as pepper, parsley and paprika, you could be sprinkling more on your food than you bargained for. Twelve percent of spices imported to the US are soiled with insects (both live and dead), animal excrement, rodent hairs and a range of other unappetizing materials, according to a new report by the US Food and Drug Administration…”

Climate Stories….

New Finding Shows That Climate Change Can Happen In A Geological Instant. This story at made me do a double-take. Remember, we don’t know what we don’t know. It’s the “unknown unknowns” that worry climate scientists the most. Tipping points? Sudden swings into a new climate state? At the rate CO2 is building up in the atmosphere anything is possible in the years ahead. Here’s an excerpt: “Rapid” and “instantaneous” are words geologists don’t use very often. But Rutgers geologists use these exact terms to describe a climate shift that occurred 55 million years ago. In a new paper in the Proceedings of the National Academy of Sciences, Morgan Schaller and James Wright contend that a doubling in carbon dioxide levels, the surface of the ocean turned acideic in over a period of weeks or months and global temperatures rose by 5 degrees centigrade – all in the space of about 13 years. Scientists previously thought this process happened over 10,000 years…”

Last Time Arctic Was This Warm Was 120,000 Years Ago. Here’s a headline that got my attention. Andrew Freedman has the story at Climate Central: here’s an excerpt: “Average summer temperatures in the Eastern Canadian Arctic during the past 100 years are hotter than they have been in at least 44,000 years, and possibly as long as 120,000 years, according to a new study. The study of mosses emerging from beneath receding glaciers on Baffin Island — the world’s fifth-largest island located west of Greenland — confirms that rapid Arctic warming has already put parts of the region in new climatic territory. Arctic warming is transforming the Far North by melting sea and land ice, speeding spring snowmelt, and acidifying the Arctic Ocean. Arctic warming may even be redirecting the jet stream in the northern midlatitudes, making some types of extreme weather events more likely in the U.S. and Europe…”

Pacific Ocean Warming At Fastest Rate In 10,000 Years. Here’s a clip from Penn State climate scientist Michael Mann at Huffington Post: “Just how rapid is the current rate of warming of the ocean? There is an interesting new article by Rosenthal and collaborators in the latest issue of the journal Science entitled “Pacific Ocean Heat Content During the Past 10,000 Years” that attempts to address this question. The article compares current rates of ocean warming with long-term paleoclimatic evidence from ocean sediments. So how rapid is the ocean warming? Well, for the Pacific ocean at least, faster than any other time in at least the past 10,000 years. The study finds, specifically, that (to quote Columbia University’s press release) the “middle depths [of the Pacific Ocean] have warmed 15 times faster in the last 60 years than they did during apparent natural warming cycles in the previous 10,000…”


Study: Northern Hemisphere Summers Now Warmest Of Last 600 Years. has the article; here’s the intro: “Summers in the northern hemisphere are now warmer than at any period in six centuries, according to climate research published on Wednesday in the science journal Nature. Harvard University researchers analysing evidence from Arctic tree rings, ice cores, lake sediments and thermometer records said recent warm temperature extremes in high northern latitudes “are unprecedented in the past 600 years” both for magnitude and frequency. “The summers of 2005, 2007, 2010 and 2011 were warmer than those of all prior years back to 1400,” they reported…”


Pacific Ocean Warming 15 Times Faster Than Before. USA Today has the story; here’s the introduction: “Although the temperature of the Earth’s atmosphere may have hit the “pause” button recently — with little global warming measured over the past few years — that hasn’t been the case with the oceans. In a study out today in the journal Science, researchers say that the middle depths of a part of the Pacific Ocean have warmed 15 times faster in the past 60 years than they did during the previous 10,000 years…”

White House Will Focus On Climate Shifts While Trying To Cut Greenhouse Gases. Adaptation and resilience will be big themes in the years and decades to come; here’s an excerpt from The New York Times: “…White House aides said President Obama would sign an executive order on Friday morning directing federal agencies to make it easier for states and communities to build resilience against storms, droughts and other weather extremes. For instance, when federal money is being spent on projects like roads, bridges, flood control and many others, the plan would encourage greater attention to the likely climate conditions of the future, which might require making the structures stronger or larger...”


Inconvenient Truth-Tellers. Climate science is under assault, because there is a mountain of cash at stake, many trillions of dollars of carbon still in the ground. Here’s a clip from a story at The Association for Psychological Science: “Throughout history, scientists have found themselves the subject of scorn, slander, ridicule and even violence when their discoveries have failed to mesh with authoritative doctrine or public sentiments. When an ancient Muslim cleric was offended by Persian doctor Rhazes’s book on medicine, he had the man beaten with his own manuscript until he was blind. After Galileo’s telescope challenged the belief that the sun orbited the earth, the Holy Office of the Inquisition accused the astronomer of heresy and sentenced him to house arrest. Today, most scientists are able to report their findings without worrying about draconian sentences from the state. But they still face the enmity of people who simply don’t believe the empirical results or who have a vested interest in the status quo…”


The Moral Imperative Of Hope And The Wasteland Of Climate Cynicism. Yes, this topic elicits cynism, anger, denial, disgust and despair, no question. Beyond the science there’s an emotional and psychological component to climate change. Here’s a clip from an interesting read at The Climate Psychologist: “…It is understandable that people would be cynical about climate change. The pain of reality is very great. It makes sense that people would pack their hearts with ice; numbing their fear and despair. This also explains why climate cynics get angry at people, such as myself, who carry a message of hope. Hope threatens the defense. Some of the ice starts to melt, and raw emotions start to come through. “You are naïve!” They tell me, trying to maintain the safe, numb feeling “You are a fool.” People cynical of romance are similarly negative towards those in love; its painful to be reminded of what you have forsaken, so they attack the reminder…”


Naomi Klein: How Science Is Telling Us All To Revolt. Here’s an excerpt of a post at New Statesman from Naomi Klein: “…We probably shouldn’t be surprised that some climate scientists are a little spooked by the radical implications of even their own research. Most of them were just quietly doing their work measuring ice cores, running global climate models and studying ocean acidification, only to discover, as the Australian climate expert and author Clive Hamilton puts it, that they “were unwittingly destabilising the political and social order”. But there are many people who are well aware of the revolutionary nature of climate science. It’s why some of the governments that decided to chuck their climate commitments in favour of digging up more carbon have had to find ever more thuggish ways to silence and intimidate their nations’ scientists…”

My Photo

Welcome to the WeatherNation blog. Every day I sift through hundreds of stories, maps, graphics and meteorological web sites, trying to capture some of the most interesting weather nuggets, the stories behind the forecast. I’ll link to stories and share some of the web sites I use. I’m still passionate about the weather, have been ever since Tropical Storm Agnes flooded my home in Lancaster, PA in 1972. I’ve started 5 weather-related companies. “EarthWatch” created the world’s first 3-D weather graphics for TV stations – Steven Spielberg used our software in “Jurassic Park” and “Twister”. My last company, “Digital Cyclone”, personalized weather for cell phones. “My-Cast” was launched in 2001 and is still going strong on iPhone, Android and Blackberry. I sold DCI to Garmin in 2007 so I could focus on my latest venture: WeatherNation. I also write a daily weather column for The Star Tribune And if you’re on Twitter, you’ll find me @pdouglasweather.
