"....At present we are stealing the future, selling it in the present, and calling it gross domestic product. We can just as easily have an economy that is based on healing the future instead of stealing it. We can either create assets for the future or take the assets of the future. One is called restoration and the other exploitation. And whenever we exploit the earth we exploit people and cause untold suffering. Working for the earth is not a way to get rich, it is a way to be rich...." - from a 2009 college commencement address by Paul Hawken.
Super El Nino?
The long-range outlook is an enigma wrapped in a riddle but every now and then Mother Nature gives off clues. The chance of an El Nino warming event later this year has risen to over 70 percent and this one may be very significant. The amount of warm water in the equatorial Pacific is greater than any time since the record El Nino of 1997-98.
A regular, garden-variety El Nino starts up in the eastern Pacific and moves west. Super El Nino events do the reverse, starting near Australia, then shifting east toward the Americas. That's what's happening in 2014. El Nino often throws a monkey-wrench into global weather, sparking droughts and floods in unusual locations, warming the atmosphere even further. 1998 was the warmest year, worldwide, on record in the 20th century.
Most, but not all, El Nino summers tend to be cooler/wetter in Minnesota, but fall/winter tends to trend warmer & drier. Details in the blog.
A sprinkle is possible this morning as temperatures limp toward 60F. Our slow-motion spring revs into high gear by midweek with T-storms; a few may become severe Thursday with highs near 80F. ECMWF models shows another soaking storm 1 week from today. No need to water anytime soon.
On May 5 I'm happy to report that snow/frost season is over.
Are We Heading For A Worrying Super El Nino? This article at Live Science, originally published by Australia's The Conversation, has details on why the brewing warm phase of Pacific Ocean water may not be a garden-variety El Nino phase; here's an excerpt: "...Recent research found that the Super El Niño events of 1982 and 1997 had a very distinct characteristic that didn’t appear until spring. Standard El Niño events warm first in the Eastern Pacific and then spread to the west. Super El Niño events do the reverse, starting in a more westerly location and then spreading east back towards the Americas. This causes much higher sea surface temperatures over a much larger area, which in turn has powerful effects on the location of rainfall and weather systems..."

Better Late Than Never. A streak of 60s for the next week, with a shot at 80F Thursday (if the sun comes out for a few hours?) Incredible. Thunderstorms are likely by Wednesday night into Thursday, when a few may turn severe. Source: Weatherspark.
Northward Jog to the Jet Stream. As the main belt of steering winds surge north the risk of strong to severe T-storms will shift into the Upper Midwest by midweek, while dry weather prevails across the Southeast and western USA. 12 km Future Radar NAM guidance courtesy of NOAA and HAMweather.
Thursday Severe Storm Threat. It's still early, but NOAA SPC is already outlining an enhanced risk of severe storms stretching from the Twin Cities to Kansas City and Dallas on Thursday. I wouldn't be surprised to see a moderate risk over Iowa and southern Minnesotay by Thursday afternoon.
Another Soggy Week East of the Rockies. The 7-Day QPF (rainfall outlook) shows 2-4" rains from near Dallas and Shreveport to Little Rock and Memphis, with some 1-2" rains by midweek over Minnesota and Wisconsin. Map: NOAA.
U.S. Corn Yields Are Growing, But So Is Sensitivity To Drought. It seems like a contradiction, until you dig into the story at Ars Technica; here's an excerpt: "...Improved drought tolerance has been one aim of crop breeding, but US corn (“maize” to much of the world) is actually becoming more sensitive to drought—likely because of one of the farming techniques being used to raise yields. Stanford’s David Lobell and a group of collaborators set out to examine recent harvests for evidence of changing drought sensitivity. They took advantage of a detailed US Department of Agriculture database that started tracking yields by field (rather than state or national totals) in 1995, and focused on Iowa, Illinois, and Indiana..."

"We Don't Know What Normal Weather Is Anymore": Confronting Extreme Weather on U.S. Farms. Here's a snippet from an article focused on what farmers are already dealing with increasing volatility in weather and longer-term climate patterns from Huffington Post: "...Now, we are at another critical moment for agriculture. Climate change is bringing more frequent and severe weather challenges, unlike any that farmers have seen before, and already farmers are feeling the effects. Countless scientists agree that climate change will affect every part of our food system—from crop yields to food processing and distribution. More dry days and hot nights will stress already limited water resources. Ironically, when it does rain, it will pour, exacerbating soil erosion. Farmers will need to confront new challenges from weeds, diseases and pests. But farmers don’t need a scientist to tell them times are tough. They can just look out their windows..."
Find Sheds New Light On 1974 Super-Outbreak in Tennessee, Alabama and Georgia. Times Free Press has an interesting story; here's a clip: "...The new data and photos beefing up documentation of the 1974 storm damage around Huntsville can help forecasters understand "what happened and what's possible in the future," he said. The super outbreaks of 1974 and 2011 "had a very large number of tornado-producing storms and many of those tornadoes were strong or violent," Bunting said. "They hit in somewhat different areas but with some overlap. I think the similarities are most important..."

Six Unbelievable Stories of Tornado Survival. Some of these video clips are pretty amazing, including this story recapping an amazing story from the 1974 Super-Outbreak, courtesy of The Weather Network: "...Around 148 tornadoes touched down in 13 states, leaving 330 people dead and more than 5,000 injured. And Linda Speakman-Yerick of Noble County, Indiana, was one of the survivors, and boy, did she have a story to tell. Speakman-Yerick was in the shower when a twister started lifting her trailer park home from the ground. As soon as she realized that was happening, out the door she went, ducking and covering next to her car. She landed next to her car, and could only watch as her home was lifted several metres off the ground, with her then-husband inside. Then it fell down. On top of her. Well, more accurately, it fell on top of the car she was seeking refuge beside, leaving her safe within a v-shaped alcove..."
Tornado Safety for Moms. I thought this was well done, and timely. Preparation is essential for everyone, but mom's juggling multiple duties and responsibilities have a unique challenge when skies turn threatening and kids are scattered across the neighborhood or county. Here's an excerpt and video from The Mom Initiative, focusing on preparation:
- "Know where safe shelters are in public places you frequent like church, the grocery store, or a mall. Spaces under wide, arched roofs are not safe.
- Teach your children to crouch down on the floor, against a wall, with their hands covering the back of their head.
- Understand the difference between a watch & a warning. A watch means conditions are “ripe.” A warning means weather is in action..."
Southwest Airlines Installs Tornado Shelters At OKC Facilities; 125 People Can Fit Inside. For metro Oklahoma City, close to Ground Zero of Tornado Alley, this sounds like a pretty good preemptive plan to me. KJRH-TV in Tulsa reports: "Southwest Airlines has installed four tornado shelters at its facility in Oklahoma City. "B Safe Shelters" spent over a year building the shelters and they believe they will keep Southwest employees safe during severe weather..."
1,100 California Fires So Far in 2015, More Than Twice The 5-Year Average, To date. NPR has an update on the critical fire risk for much of the western USA, and how forestry officials are in a race to burn fuel early, to try and play offense instead of defense: "...In a normal year, there'd still be snow on the ground. Not having snow raises the risk of fire. "With the drought that we've had last year into this year, fuels are ready; they're susceptible to burn," says Nathan Judy, a fire information officer for the nearby Angeles National Forest. "Fuel," in this context, means the grasses, brush and trees that feed wildfires. The Mount Baldy community is trying to mitigate that risk by cutting and gathering those fuels, then burning the material on their terms..."

Canada and USA Move 20 Feet Apart - On Purpose. Robert Krulwich has the unlikely story of how our neighbor to the north OK'd a 20 foot buffer zone, and how the border is anything but straight; here's an excerpt from NPR: "The U.S. and Canada may be as lovey-dovey as two neighbors can get, but according to this charming video history by , both countries agreed to tuck themselves a little bit in, 10 feet back for America, 10 feet back for Canada, creating a corridor of open, surveillable, clear space between them..."

Climate Change Is Clear and Present Danger, Says Landmark U.S. Report. The Guardian has details; here's the introduction: "Climate change has moved from distant threat to present-day danger and no American will be left unscathed, according to a landmark report due to be unveiled on Tuesday. The National Climate Assessment, a 1,300-page report compiled by 300 leading scientists and experts, is meant to be the definitive account of the effects of climate change on the US. It will be formally released at a White House event and is expected to drive the remaining two years of Barack Obama's environmental agenda..."
Best Environmental Commencement Speech Ever? This redefines eloquent prose, and explains, brilliantly, what we're up against, and how our better angels will needed, on a global scale, to reverse some of the damage we're doing to the planet, to our home. Here's the introduction of a moving commencement speech Paul Hawken made at The University of Portland, entitled "You are Brilliant, and the Earth is Hiring", excepted from an article at Huffington Post: "...You are going to have to figure out what it means to be a human being on earth at a time when every living system is declining, and the rate of decline is accelerating. Kind of a mind-boggling situation... but not one peer-reviewed paper published in the last thirty years can refute that statement. Basically, civilization needs a new operating system, you are the programmers, and we need it within a few decades. This planet came with a set of instructions, but we seem to have misplaced them..."

Preparing Boston For High Sea Levels. The Boston Herald has the article; here's a snippet that caught my eye: "...The U.N. Intergovernmental Panel on Climate Change estimates that seas will rise between 3 and 6 feet by the end of this century. Because of how Greater Boston is situated, it will be disproportionately affected, said Dennis Carlberg, sustainability director at Boston University and co-chairman of the ULI Boston Sustainability Council. Scientists project changing climate conditions will cause Boston Harbor to be as much as 6 feet above current levels, and more than 30 percent of the city will flood during storms at high tide...."

Why Should Evangelical Christians Care About Climate Change? Slate interviews climate scientist Katharine Hayhoe, who just happens to be an Evangelical Christian as well. Here is her response to the question raised by some: "God would never allow this to happen": "....Hayhoe thinks the answer to Inhofe’s objection is simple: From a Christian perspective, we have free will to make decisions and must live with their consequences. This is, after all, a classic Christian solution to the theological problem of evil. “Are bad things happening? Yes, all the time,” says Hayhoe. “Someone gets drunk, they get behind the wheel of a car, they kill an innocent bystander, possibly even a child or a mother.” Climate change is, to Hayhoe, just another wrong, another problem, brought on by flawed humans exercising their wills in a way that is less than fully advisable. “That’s really what climate change is,” she says. “It’s a casualty of the decisions that we have made...”
Think The Climate Change Fight is Tough? What About the 17th Century Fight over Math? Here's some good perspective on climate change science as a proxy for something much bigger - and why there's so much resistance in some quarters to accepting the science. I found this story at The Los Angeles Times fascinating - here's a clip: "...As with climate change today, only a small number of professionals were truly qualified to evaluate the respective merits of the two approaches. But this did not prevent kings and cardinals, religious orders, social reformers and political theorists from charging into the fray to pronounce on the matter. As they well knew, the question might be technical and narrow but the implications were immensely broad. At stake was nothing less than the shape of the modern world, then coming into being..."
