"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."

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

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

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."

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."

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."

Deadly Tornado Myths
What keeps me up at night? The specter of a large, violent tornado steam-rolling into a major U.S. city, catching thousands off-guard. Statistically, it's only a matter of time. As I described in an earlier post hundreds, maybe thousands will be killed and injured from a single metro tornado. There will be Congressional inquiries. "How could this happen - why weren't we prepared?"
There's a dangerous urban myth that tornadoes can't hit cities or close-in suburbs. Not true. As cities expand into farmland we are increasing the potential for a tornado tragedy.

Often deniers portray themselves as   reasoned, cautious, and conservative scientists, while the real   scientists working in the field are described with emotionally charged   adjectives like "alarmists," "warmists," and the like to weaken the   public's respect for their work and to fool journalists about who's who.   If you can degrade, mock or destroy the individual, then it's easier   for the public to dismiss everything that individual said."The unbridled  advocacy of CO2 being  the major cause of climate change is unbecoming  of NASA’s history of  making an objective assessment of all available  scientific data prior to  making decisions or public statements."So here  we see fifty years of science manipulatively described instead as  "unbridled advocacy." - excerpt from

Climate Stories...
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 anti-science 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."

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."
