73 F. high temperature in the Twin Cities Saturday.
57 F. average high for April 14.
48 F. high a year ago – April 14, 2011.
1.54″ rain predicted for the Twin Cities by Monday morning (00z NAM model)
Slight severe threat from the Twin Cities south/east (moderate risk over Wisconsin). As many as 3-6 tornadoes may drop between La Crosse, Madison, The Dells, Wausau and Appleton.
30-40 mph winds possible later tonight as temperatures drop nearly 30 degrees.
36 F. predicted temperature at 7 am Monday (very slight chance of flurries, mainly north metro).
70s likely again between April 24-30.
“Wedge.” This was the scene Saturday evening near Salina, Kansas – hit by two tornadoes in the same day! Thanks to Matt Unruh from Lawrence, Kansas for sharing this. He was southeast of Salina when he took this pic – that’s probably an EF-3 tornado over the ridge, winds 120-145 mph?
Moderate Severe Threat Today. Although not as widespread and severe as yesterday, I expect a few more tornadoes today, as close as far southeastern Minnesota and central and southern Wisconsin, where the wind, moisture and instability field is ripe for more “supercell” thunderstorms, capable of large hail and a few tornadoes. If you’re driving east on I-94 or southeast down Highway 61 toward Winona and La Crosse, the risk of severe weather will increase the farther south/east you travel. Stay alert (local media, e-mail alerts, smartphone apps, etc). Do NOT rely on the sirens. Map courtesy of SPC.
Tornado Risk Over Southeastern MN? This is the “Tornado Composite” Field for the morning hours today, showing a significant risk over southeastern Minnesota through midday, sufficient low-level wind shear and instability (and a vigorous frontal boundary) capable of spinning up a few tornadoes. Graphic courtesy of Earl Barker’s excellent Wxcaster site – thanks to Randy Peterson for bringing this to my attention.
Nagging Severe Risk. Although the best dynamics will stay south/east of MSP, vertical velocities, a measure of upward motion overhead, are forecast to reach +21.1 this evening with a lifted index of -4, sufficient wind shear and instability for a few severe storms again by late afternoon/evening as a vigorous cold front approaches. Stay alert today. Total rainfall amounts are forecast to reach 1.54″ by Monday morning.
118 Tornado Reports…And Counting. O.K. I posted this at 12:15 am Sunday. SPC reported 118 (preliminary) reports on Saturday, but that count will probably rise. You can instantly see the tracks of long-lasting, violent EF-2 to EF-4 strength tornadoes from Oklahoma northward to Iowa. SPC did an amazingly good job pin-pointing where these tornadoes would touch down. Everyone is so quick to criticize – let’s give credit where credit is due.
Wichita Nightmare. I was running around like a crazy-man Saturday (along with most of my staff at WeatherNation TV), covering what may have been the biggest, or at the very least the Top 2-3 tornado outbreaks of 2012. I took a few pics (from GR2 Analyst) of the supercell moving into Wichita: reflectivity upper left, velocity field upper right. There were reports of a 1/4 to 1/2 mile wide wedge moving across the south side of Wichita, hitting Wichita’s main airport and McConnell Air Force Base. Authorities won’t know the full extent of damage, injuries and possible fatalities until this morning.
* The New York Times has a story about Saturday’s outbreak here.
Temperature Trend: “E-Ride At DisneyWorld”. From 70 to 30s in the span of about 18 hours, sparking high winds tonight (gusting past 40 mph). Highs will be stuck in the mid 40s tomorrow, a wind chill dipping into the 20s. Readings recover a bit by midweek, after a risk of patchy frost Tuesday morning. I don’t expect a widespread freeze this time around.
European Solution. The ECMWF (which often does a – much – better job than the GFS model) shows highs near 60 Tuesday and Wednesday, again next Sunday – readings approaching 70 a week from tomorrow.
Lukewarm Last Week Of April. The GFS shows a run of 70s, even a shot at 80, during the last week of April, over half an inch of rain possible between April 25-28. We need 3-6″ of additional rain to pull out of our long-term drought.
1,400. Average number of tornadoes every year across America. Fewer than 1% will reach EF-4 or EF-5 strength.
13 minutes. Average lead time for a tornado in the USA (time from when a warning is issued until arrival).
6-7 minutes. Average lead time in 1975.
+2.5 F. Water temperatures in the Gulf of Mexico were 2.5F warmer than average in March, the mildest ever observed. Meteorologists are concerned that this added warmth and moisture over the Gulf may be a factor in what is turning into an especially severe tornado season across the USA. Details below.

Growing Potential For A Major Tornado Tragedy. We’ve been (very) lucky that a major tornado has not hit a heavily populated area in Tornado Alley recently. Meteorologically – there is nothing preventing a large, violent tornado from hitting a close-in suburb or even a downtown. Here’s a recent story I wrote for Huffington Post, highlighting the potential for a major loss of life from a “wedge” striking a major population center. Tim Marshall, a meteorologist and structural engineer, recently warned “there will be 1,000 or more deaths from a single tornado hitting a major population center in the near future.” I hope he’s wrong – but, like many meteorologists, I’m worried about complacency and apathy. You’d be amazed at the number of otherwise logical people who believe living in a city insulates them from tornadoes. Nothing could be farther from the truth.

“According to the Mayo Clinic, “If you’re in denial, you’re not being realistic about something that’s happening in your life — something that might be obvious to those around you.” … But like the Mayo Clinic writes, “(D)enial has a dark side. Being in denial for too long can prevent you from effectively dealing with issues that require action.” – from a blog post at redding.com; details below.
“Tornadogenesis” Although the exact mechanism is still unclear, meteorologists theorize that a (warm/buoyant) downdraft, called an RFD, or rear-flank downdraft, wrapping around a spinning supercell, may be the mechanism that focuses horizontal wind shear about a vertical axis, stretching the rotating, violently rising column of air within a severe thunderstorm into a tight vortex, the tornado signature. The map above is from twisterdata.com, valid at 7 pm this evening. I’m most concerned about Omaha, Lincoln, Sioux City, even the suburbs of Des Moines – best chance of a few large, violent tornadoes between 5 pm and 9 pm this evening.
Dangerous Tornado Outbreak Expected Saturday; Gulf of Mexico SST’s Warmest On Record. Here’s an excerpt from Jeff Master’s Wunderblog – he points out record warm water temperatures in the Gulf of Mexico: “Temperatures in the states bordering the Gulf of Mexico were the 3rd – 7th warmest on record during the first three months of 2012, according to NOAA’s National Climatic Data Center. This allowed Sea Surface Temperatures (SSTs) in the Gulf of Mexico (25 – 30°N, 85 – 90°W) to climb to 1.4°C (2.5°F) above average during March 2012, according to a wunderground analysis of the Hadley Centre SST data set. This is the warmest March value on record for the Gulf of Mexico, going back over a century of record keeping.“

SSTs in the Gulf of Mexico are at their warmest levels on record for this time of year. Follow Weather Underground on twitter for the latest on this potential severe weather outbreak.“
Learn About Extreme Weather’s Local Impact. Based on the last 6-7 years I’m thinking of moving to northeastern Minnesota, where there have been NO major weather-related disasters. Why is this? All I can think is that a persistently chilly wind off Lake Superior innoculates much of the Northland for large, violent tornadoes and tends to dampen many of the most severe T-storms. Details from Environment Minnesota. “Click on your county to see a tally of weather-related disasters since 2006. Extreme weather is happening—and it’s causing extremely big problems. To make matters worse, global warming increases the likelihood that we’ll see even more extreme weather in the future. To tackle this threat, we must cut the carbon pollution from power plants, cars and trucks, and other sources that fuels global warming.”
A Touch Of ….Snow Up North? The latest NAM model (00z) prints out some 2-5″ snowfall amounts over far northeastern Minnesota, from Lutsen to Grand Marais. We could wake up to a few flurries Monday morning – but with warm ground temperatures nothing will stick. I pray.
Monday F-F-Flurries? Here’s the latest NAM model, showing accumulated snowfall by Monday evening, a couple inches over the North Shore and BWCA -maybe a few renegade flurries into the metro early tomorrow. Something to look forward to. We’ll see. Map from policlimate.com.
Dry Start To Growing Season. Here’s an excerpt from Dr. Mark Seeley’s Friday WeatherTalk blog: “With field working season underway, and some of the state’s 2012 crops already in the ground many Minnesota farmers are waiting for rain to replenish the dry soils that were a carryover from last year. The precipitation deficiency reported by some climate observers is very significant. There are many areas of the state that have reported precipitation totals since last August (a period of 8.5 months) that are more than 7 inches behind normal values for the period. Some of these locations are in the list below, showing how the deficiency for this 8.5 month period ranks historically.
Location; Precipitation Total; Departure from Normal; Historical Rank
Lamberton; 5.35 inches; -7.51 inches; Driest of record
Winnebago; 8.03 inches; -7.17 inches; Driest of record
Marshall; 4.66 inches; -8.69 inches; 2nd Driest
Granite Falls; 4.89 inches; -7.82 inches; 3rd Driest
Lake Minnetonka Conservation District Initiates “Low Water Declaration”. I know I should have gone into propeller repair (or the dock business). Plan on a few extra dock sections this summer, whatever lake you’re hanging out on. More from LMCD: “When Lake levels fall below 928.0 feet, the Lake Minnetonka Conservation District (LMCD) Code states that the Board of Directors may approve a resolution that allows for temporary dock length extensions for licensed (multiple dock facilities) and unlicensed (primarily residential) sites on Lake Minnetonka. The LMCD Board of Directors has been considering this matter based on water level readings provided by the Minnehaha Creek Watershed District since mid-March, as well as projected precipitation. Based on those findings, a resolution was adopted at the April 11th Regular LMCD Board Meeting declaring “Low Water” on Lake Minnetonka. This resolution authorizes temporary dock extensions per LMCD Code.” (I snapped this photo back on March 13).
Latest Army Corps Analysis Says 2011 Flood Was “Beyond Control”. Here’s an excerpt of an interesting story from journalstar.com: “Even if the U.S. Army Corps of Engineers had released water at record levels from Gavins Point Dam for 365 consecutive days, it wouldn’t have been enough to prevent serious flooding on the Missouri River in 2011. That was one of the findings in an analysis the corps released on Friday about possible adjustments in flood control storage. The size of the 2011 challenge begins with the 61 million acre feet of runoff in the basin, said Brig. Gen. John McMahon, commander of the corps’ Northwest Division and a key figure in the operation of Gavins Point and five other main-stem dams.”
Kansas Storm Chaser/Photographer Sues Over Montana Wreck Of SUV. When I’m chasing tornadoes (think of how insane that sounds) I’m not so much worried about the tornado. I am worried about hail, cloud to ground lightning, and getting creamed by a guy in a pickup driving 100 mph to catch up to a supercell. I’m amazed there haven’t been any fatal accidents, to date. But dodgeglobe.com has a cautionary tale about the perils of taking your favorite vehicle into Tornado Alley: “A Kansas storm chaser and photographer is suing a motorist whose car struck his SUV during a Montana snowstorm, alleging that the wreck destroyed a vehicle that had “unique value” for surviving more than 350,000 miles through hurricanes, tornadoes and other extreme weather. Jim Reed of Wichita, Kan., filed the lawsuit April 6 in Helena against an East Helena man involved in the November 2010 crash. He is seeking unspecified compensation for his cranberry-colored SUV and his injuries, the Independent Record (http://bit.ly/HDLgyQ ) reported Thursday. Reed said his 1994 Ford Explorer was featured in much of his work, including a two-page spread in the June 2009 issue of National Geographic, and in a 2009 series on the Speed Channel.”
2012 Wildfire Season: States Prepare For Dangerous Fires. It is a bit troubling that we’re seeing so many fires so early in the season. Our fast-forward spring has accelerated the frequency and intensity of wildfires and forest fires. It may be a long, hot (and fiery) summer for much of the western USA. Huffington Post reports: “DENVER — The West’s 2012 wildfire season exploded in earnest last month with a wind-whipped blaze that killed three people in rugged alpine canyon country near Denver. It took a 700-strong federal firefighting team a week of labor, day and night, to tame the blaze – and other states throughout the West took notice. Fire experts say this year’s drought, low snowpack and record-high temperatures in much of the West portend a dangerous installment of what has become a year-round wildfire threat. Wildfires burned more than 1,500 square miles in Arizona last year and have already torched about 12 square miles this year. Most were caused by people, and fire officials hope the public has learned some lessons from the Wallow Fire, the worst in state history. Campfire embers ignited a blaze that forced nearly 10,000 people to evacuate their homes.” Photo above courtesy of AP.
“Irene” Retired From List Of Atlantic Basin Storm Names. From NOAA: “Irene has been retired from the official list of Atlantic Basin tropical storm names by the World Meteorological Organization’s (WMO) hurricane committee because of the fatalities and damage it caused in August 2011 and will be replaced by Irma. Storm names are reused every six years for both the Atlantic Basin and eastern North Pacific Basin, unless retired for causing a considerable about of casualties or damage. Irene is the 76th name to be retired from the Atlantic list since 1954. Irene became a hurricane on Aug. 22 and intensified to a Category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale on Aug. 24 while centered between Mayaguana and Grand Inagua in the Bahamas. It gradually weakened after crossing the Bahamas, making landfall in North Carolina on Aug. 27 as a Category 1 hurricane. Irene made another landfall the next day as a tropical storm very near Atlantic City, New Jersey. The center moved over Coney Island and Manhattan, New York, the same day.” Hurricane Irene image courtesy of NASA.
Irene Replaced By Irma On Atlantic Hurricane Name List. Nola.com in New Orleans has a slightly different perspective on the “retirement” of Irene’s name from the master list; here’s an excerpt: “The World Meteorological Organization has dropped Irene from its six-year list of names for tropical storms and hurricanes because of the fatalities and damage caused by Hurricane Irene last August. Irma will replace it on the list, and could be first used in 2017. Irene is the 76th name to be retired from the Atlantic list since 1954.”
Thailand’s Blueprint To Reign In Fallout From Floods And Drought. An interesting story from The Christian Science Monitor; here’s an excerpt: “Despite seeing his 60 acres of rice paddies covered in more than 10 feet of water for three months during late 2011, farmer Tawee Wongsan is sanguine about flooding this year. “I don’t think there will be flooding this year,” he says. “The water in the big dams is not so high like last year.” Last year’s floods killed more than 800 people and caused an estimated $40 billion damage to the country’s $345 billion economy, which is the world’s 25th largest. Water covered several districts of Bangkok and swamped industrial zones that include vital automobile and electronics sectors, disrupting global supply chains.”

New “Future Earth” Exhibit At St. Paul Science Museum Opens Next Saturday, April 21. This will be a must-see exhibit, and there’s added incentive to attend the Grand Opening a week from today. Details from The Science Museum: “What will Earth be like in 2050 with 9 billion people? No one knows. But as the healthiest, wealthiest, most educated and most connected population in Earth’s history, we’re in a good position to face the challenges ahead. Join us in exploring Future Earth!
The 10 Worst Jobs Of 2011. What in God’s name is a “roustabout”? You’re about to find out. This list is making news. Is your job in the Top 10? More from careercast.com: “From bad to worse: thanks to upheaval in the oil industry, Roustabout ranks as the Worst Job of 2011 – its second straight year in last place. Twelve-hour shifts, exposure to the elements in hostile environments, low pay, high risk of injury and isolation from loved ones for weeks at a time are just some of the factors that combine to make Roustabout the worst job of 2011. As the key providers of maintenance for oil rigs and pipelines, Roustabouts routinely perform backbreaking labor at all hours of the day and night in conditions that can range from arctic winters to desert summers to ocean storms. They even face the threat of attack in unstable parts of the world. Braving these inhospitable surroundings, Roustabouts work on the front lines, getting hands-on with dangerous drilling equipment and risking serious injury or worse – as last year’s explosion at the Deepwater Horizon facility in the Gulf of Mexico illustrates. Why does Roustabout rank as the worst job of 2011, as opposed to other worst jobs such as Lumberjack or Construction Worker? Surveying 200 different jobs, the Jobs Rated report ranks professions according to five core criteria: Work Environment, Physical Demands, Outlook, Income and Stress.”
“Astrada” Superyacht Launches In China. How long before one of these shows up on the St. Croix River? Gizmag.com has the decadent details: “….The finished product is worth US$15 million, and will likely be used by Marden and his wife Elaine to sail between two islands that they own off the coast of Indonesia. The trimaran measures 42.5 by 16 meters (139.5 by 52.5 feet), and weighs 52 tons (47 tonnes). It has a top speed of 22.5 knots, although at 17 knots it has a remarkable range of 4,000 nautical miles (7,408 km) – this comes thanks largely to a lightweight hull made from a glass/Kevlar foam sandwich material, a superstructure made from carbon fiber with a honeycomb core, and other weight-saving and streamlining considerations. Its fuel economy is estimated at 90 liters (24 U.S. gallons) per hour at 13 knots, or 120 liters (32 gallons) per hour at 17 knots.”
Hi Roger. It’s Me, Joe: The “Fox Mole”. It’s fascinating what some publications will do for a scoop; details from gawker.com: “Hi. My name is Joe Muto. I was the Fox Mole. Two hours ago I was called into a meeting with Dianne Brandi, the Fox News Executive Vice President of Legal and Business Affairs and suspended indefinitely… with pay, oddly enough. They nailed me. In the end, it was the digital trail that gave me away. They knew that someone, using my computer login, had accessed the sources for two videos that ended up on Gawker over the past few weeks. They couldn’t prove it entirely, but I was pretty much the only suspect. I denied it, which is why they didn’t fire me outright. But two nice gentlemen from security escorted me to my desk to pack up my stuff, and it was pretty obvious at that point that I would not be setting foot back into 1211 Avenue of the Americas again.”
A Fool’s Paradise. Was Instagram Too Free To Last? Another fascinating story from one of my favorite sites (you can sign up for a free, daily HTML e-mail with story highlights) at gizmag.com. Here’s an excerpt: “…The fact is, no one except a handful of people inside Instagram and Facebook knows what the future holds, though it’s certainly true that if we look to acquisitions of the past for clues, there are worrying precedents – even if we limit the field down to the services Facebook has itself obtained (recall Gowalla). A question fewer people seem to be asking is was such a takeover inevitable, given that Instagram is a free download. Since its launch 18 months ago, Instagram has attracted a community 35-million strong, but apart from investment it hasn’t generated a bean in revenue. One has to wonder, of that part of the community that is now jumping ship for competing services, what on Earth did they think was going to happen? The situation as it was couldn’t continue indefinitely.”
Pinpoint Unsavory Elements In Your Neighborhood With The “Criminal Tracker” App. Live in a rough neighborhood – worried about personal safety? There’s an app for that. Here’s an excerpt from gizmag.com: “U.S. Publications Inc says that a study by the U.S. Department of Justice has revealed that sex offenders are four times more likely to re-offend than other convicted criminals, and that 60% of convicted sex offenders are out on parole or probation. Playing on the fear that there could well be just such a person living secretly in your neighborhood, the company has announced a new app that’s said to be capable of pointing out the location of such undesirables within a 40 mile (64 km) radius of a given area. The Criminal Tracker app doesn’t limit its results to sex offenders, however, as the company’s database is claimed to be the most comprehensive National Criminal Index available.”
Gorgeous – And “Average” For May 29. Yes, this is why we stay. That, and occasional 22″ winters. Under a mostly-blue sky Saturday highs ranged from 57 at International Falls to 70 Alexandria, 73 Twin Cities, and 74 at St. Cloud. By late afternoon severe thunderstorms bubbling up over Iowa swept a canopy of high, thin, cirrus clouds over the metro, keeping us 1-2 degrees cooler than we would have been, otherwise. Still – what a day.

Stopping Climate Change Is Much Cheaper Than You Think. An intriguing story in The Atlantic: “You’ve heard it before: politicians say they’d love to take action against climate change, but they’re reeling from sticker shock. Today, a new report from the UK’s leading climate change watchdog refutes this oft-cited argument that climate action will herald economic Armageddon. The Committee on Climate Change report, with the hairy-sounding title “Statutory Advice on Inclusion of International Aviation and Shipping,” says that in 2050, the UK’s emissions reductions across the whole economy will cost 1-2 percent of the total GDP. This updates, in greater detail, the range predicted half a decade ago by the watershed Stern Review.“

Overcoming Climate Change Denial. Here’s an interesting post from Doug Craig at redding.com: “All of us are in denial about something some of the time. I know I am going to die someday and chances are I am going to suffer before that happens. Or it is possible people I love and care about might suffer or die. I really don’t want to think about that too much. I like to pretend that bad stuff is so far away, that it’s like it does not or will not ever exist. I know that the climate is changing and it is going to be bad and I blog about it an awful lot. I know I am obsessed about it and have been for over six years now. I know what is coming and yet like everyone else, sometimes I pretend it isn’t coming. It’s how I cope with the stuff I can’t control.”
How Green Are Electric Cars? Depends Where You Plug In. Here’s an excerpt of a story at The New York Times: “The answer may be a surprise. According to a report that the Union of Concerned Scientists plans to release on Monday, there would be a considerable difference in the amount of greenhouse gases — primarily carbon dioxide — that result from charging the cars’ battery packs. By trapping heat, greenhouse gases contribute to climate change. The advocacy group’s report, titled “State of Charge: Electric Vehicles’ Global Warming Emissions and Fuel Cost Savings Across the United States,” uses the electric power requirements of the Nissan Leaf as a basis for comparison. The Leaf, on sale in the United States for more than a year and the most widely available electric model from a major automaker, sets a logical baseline.”
NASA Climate Change Letter Belongs To Long Tradition Of Fake Expertise. More from Huffington Post: “WASHINGTON — When former NASA administrators, astronauts and engineers released a letter earlier this week attacking the science of climate change, its veneer of legitimacy kicked off a media blitz. Yet none of the letter’s 49 signatories are climate scientists, and with more than 18,000 people currently working for NASA, to say nothing of the tens of thousands more who are retired, the letter seems more than anything like a empty publicity stunt — for which there’s considerable precedent. “This is an old stunt,” explained Michael Mann, a well-known climate scientist and Penn State professor. “When you have an area of the science where there is a consensus like in climate change, where the problem is real and the scientific implications are on a collision course with vested interests like the fossil fuel industry, you often see this.”
From A Boy Who Loved NASA: How Could 49 Former NASA Astronauts And Scientists Soil Their Good Names Over Climate Politics? An important post from Shawn Lawrence Otto at Neorennaisance: “When I was a boy, I loved NASA. So imagine how pleased I was to be invited to speak at NASA Goddard Space Flight Center this week – where the kindly, soft-spoken and brilliant Willy Wonka of the place, astrophysicist John Mather, and his team are building the James Webb Space Telescope – perhaps humanity’s most ambitious engineering project – and where scientists use satellites to study climate change in incredible detail. My talk, on Wednesday, was about the subject of my new book, called Fool Me Twice: fighting the assault on science in America, and how NASA scientists, particularly NASA climate scientists, could communicate complex science in the face of antiscience attacks, such as those by global warming deniers. At that very moment a living example was was happening all around me. I started getting texts, tweets and emails about 49 former NASA employees who were taking the agency to task for publishing information on climate change.”
49 Cliff Clavin’s Walk Into A Bar And Talk Climate Change. A post related to the indignant NASA astronauts from local St. Thomas professor John Abraham at desmogblog.com: “You could almost set your watch by it. It has become a regular absurdity that a bunch of non-scientists try to tell the world that they know something the experts don’t. Those of us who watched that iconic television show called Cheers remember Cliff, the mailman. He considered himself the expert on everything even though it was painfully obvious he knew very little about anything. Well we got our latest batch of Cliff Clavin wisdom this past week when 49 former staff members from NASA wrote a letter to NASA administrators decrying the work that the organization does on climate. It makes one wonder what the thousands of current NASA employees think of their former colleagues.”
On The Intellectually Empty, Politically Motivated Attacks On NASA Climate Scientists By Former Astronauts. Wait a minute – astronauts are lecturing climate scientists (in their own organization) about climate science? Am I missing something here? It would be like a NASA climate scientist giving John Glenn tips on how to correct a burn to reach low-Earth orbit. Huh? More on this tempest in a NASA-teapot from Climate Science Watch: “With the 2013 NASA budget endangered by upcoming votes in Congress, attacks on Earth Science (where climate research and observing systems are funded) are to be expected. A denial machine letter signed by 49 former NASA administrators, astronauts, and engineers – i.e., folks who want to steer budget cuts away from human space flight – stoops to attacks on NASA climate scientists, essentially calling for them to be disowned and muzzled by their agency. The letter signers collectively have zero climate science expertise or relevant publications, in contrast with the NASA climate scientists, who are leaders in climate change research with a mountain of peer-reviewed publications. And endless impediments to honest discourse and meaningful action.”

Public Understanding Of Climate Change: Getting Warmer. From Climate Progress and grist.org: “To go by the polls, the high point of public understanding of climate science was 2006 to 2008. That’s no surprise, since that period saw a peak in media reporting on climate science, starting in 2006 with An Inconvenient Truth, the documentary of Al Gore’s PowerPoint presentation on climate science, and continuing in 2007 with the four scientific assessment reports of the Intergovernmental Panel on Climate Change.” Graphic above courtesy of Gallup and grist.org.
How Climate Change Makes Trees Sick. Here’s an excerpt of a story from KQED-FM, public radio for northern California: “A patch of tanoak, killed by Sudden Oak Death, in the Los Padres National Forest in Monterey County. Climate change is likely to wreak havoc on California’s forests. Extreme weather, wildfires and insect outbreaks will all take a toll. Add to those another looming threat: disease. Forest diseases like Sudden Oak Death, which has infected trees in 14 counties in the state, stand to benefit from the effects of climate change, to the detriment, obviously, of the trees. Trees are big and long-lived. Tree pathogens, mostly fungi and bacteria, are the opposite. They’re mobile, able to blow around on the wind. And they reproduce and evolve rapidly. That’s the crux of the problem, according to Susan Frankel, a plant pathologist with the Forest Service.”
Rising Pacific Seas Linked To Climate Change. Here’s an excerpt of a story at Mother Nature Network: “SYDNEY — Sea levels in the southwest Pacific started rising drastically in the 1880s, with a notable peak in the 1990s thought to be linked to human-induced climate change, according to a new study. The research, which examined sediment core samples taken from salt marshes in southern Australia’s Tasmania island, used geochemistry to establish a chronology of sea level changes over the past 200 years. Patrick Moss, from the University of Queensland, said major environmental events that impacted the ocean, such as the introduction of unleaded petrol and nuclear tests, showed up in the samples and were used for dating.”

Addressing Climate Change Through Diet. From VOA, Voice of America: “A new study says one of the best ways to curb greenhouse gas emissions is to eat less meat. In fact, the study says meat consumption in the developed should be cut by 50 percent per person by 2050.”
