Jordan Flaherty has produced a great video on the situation with the Bayou Corne sinkhole in Louisiana. Especially encouraging to me were the interview segments with Wilma Subra and Lt. General Russel Honore. I'm really glad the people of Bayou Corne and Grand Bayou have support from folks of this caliber as they seek justice for corporate destruction of their communities.
About the video: The Bayou Corne Sinkhole is a window to the devastation that the
petrochemical industry has caused in Southern Louisiana. Featuring
correspondent Michael Okwu, produced by Jordan Flaherty, filmed by
Fletcher Johnson, edited by Leila Garcia. Interviews with Lt. General
Russel Honore, WIlma Subra, Anne Rolfes, Mona Degas, Michael Schaff,
Sonny Cranch, Michael Courreges, and Carla Alleman. Aired on America

I'm getting a lot of interesting photos and updates from friends who live in the Boulder area. One of the most amazing things to me is the geographical extent of flooding. Some information on the weather patterns that created such extreme rainfall is coming out...really interesting stuff. Unfortunately there is also a growing list of people who are unaccounted for. Here are some links to articles that include some of the newer info:
My body is still in Tennessee today but my heart and mind are with friends, colleagues and relatives in Colorado.
I was living in Allenspark in 1976 when 8 inches of rain fell in one hour (and more than 12 inches in less than 4 hours) over the Big Thompson watershed to the north of us. The 20-foot wall of water that scoured the canyon that night took around 143 human lives and left us all with memorable images of the power of natural forces in extreme weather.
Just six years later, on July 16, 1982, the Lawn Lake dam -- an earthen structure high in the same larger watershed in Rocky Mountain National Park -- collapsed. As the flood water hit the Cascade Dam a couple of miles downstream, it too collapsed. This flood killed 3 people and did about $31-million in damage to Estes Park and communities further downstream.

As a former active member of the Boulder County fire and emergency services community, I trained with and had many friends among the mountain fire departments such as Four Mile and Lefthand Canyon that are no doubt very busy today with too much -- rather than too little -- water, and have suffered some painful losses in their communities with this flooding.
If you have travelled any of these canyons that shuttle water out of the Rocky Mountains to the valleys below, you may have seen "climb to safety" signs spaced out along the routes. Placement of signs, upgrading flood watch protocols and, in Rocky Mountain National Park, the removal of old dams following these major events reflected the sharper attention to flash flood potential and its deadly consequences.
I hope that efforts taken back then to improve safety of citizens and emergency response in flood conditions gave Boulder, Larimer and other Colorado counties a better chance to avoid loss of life over the past couple of days. I hope that the lives lost so far in Boulder County will be the only ones, and that preparation for such events by first responders and law enforcement officers will help them stay safer as they do their jobs for their communities in these 2013 floods.
I have photos of Big Thompson and Lawn Lake flood damages but have not scanned them from slides yet. If I can find them, I'll post an update to this post.
Stay safe, everybody!
Here are some links to coverage of Colorado flooding:
In light of extreme flooding going on in Boulder County, Colorado, this week, this new report might be useful for connecting to broader perspectives on the relation of mega-weather events and climate change:
Human influences are having an impact on some extreme weather and climate events, according to the report Explaining Extreme Events of 2012 from a Climate Perspective released September 5, 2013 by the Bulletin of the American Meteorological Society. Scientists from NOAA served as three of the four lead editors on the report. Overall, 18 different research teams from around the world contributed to the peer-reviewed report that examined the causes of 12 extreme events that occurred on five continents and in the Arctic.
While several thousand square kilometers of land area have been subject to surface mining in the Central Appalachians, no reliable estimate exists for how much coal is produced per unit landscape disturbance. We provide this estimate using regional satellite-derived mine delineations and historical county-level coal production data for the period 1985–2005, and further relate the aerial extent of mining disturbance to stream impairment and loss of ecosystem carbon sequestration potential. To meet current US coal demands, an area the size of Washington DC would need to be mined every 81 days. A one-year supply of coal would result in ~2,300 km of stream impairment and a loss of ecosystem carbon sequestration capacity comparable to the global warming potential of >33,000 US homes. For the first time, the environmental impacts of surface coal mining can be directly scaled with coal production rates.

Also check out this 3-D analyzation of Bopha provided by NASA's TRMM satellite, and related article linked below.
Some of the hashtags being used on Twitter are #Pablo, #PabloPH, #Bopha, and #Philippines. I found many good informational links being shared there, as well as wishes from people around the world for the well-being of survivors.
Interesting article about a community that has contributed very little to climate
change, but are feeling the effects in profound ways.
For the most part, many people still experience climate change on an academic rather than a personal level. But for the villagers of Vunidogoloa on Vanua Levu, Fiji’s second largest island, climate change has become a daily intrusion on every day life. The villagers of Vunidogoloa are currently relocating to drier and higher land because of sea level rise, erosion, and intensifying floods. I had the opportunity to visit the village midway through this process – one of the very first village relocation projects in the world – and spoke with people young and old about their upcoming move.
I've been following impacts of this derecho through email and social networks the past few days. The first sentence in the Earth Observatory article below really helped knit all the stories I've been hearing into a larger picture of this systemic awesome event.

On June 29, 2012, a windstorm started in northwestern Indiana, and traveled roughly 600 miles (1,000 kilometers) eastward to the Atlantic Ocean. Embarking on a roughly 10-hour journey, the fast-moving storm toppled trees, downed power lines and left more than a million residents without power in the District of Columbia alone.
Steady progress corralling New Mexico's largest ever forest fire allowed some evacuees to return home on Monday even as officials in Utah investigated an air tanker crash that caused the first two deaths among crews fighting wildfires this year.
The airplane, a Lockheed Martin P2V, went down on Sunday afternoon in the Hamlin Valley area of southwestern Utah while on a mission to drop chemical fire retardant on an 8,000-acre (3,237-hectare) blaze along the Nevada-Utah border.
The Whitewater-Baldy Complex fire has burned 259,025 acres and is 20% contained, according to today's briefing. Fire behavior was dampened earlier in the day by an inversion over the fire.
A Forest Service Burned Area Emergency Response (BAER) team is on the ground now for an assessment of the Whitewater-Baldy Complex burn area. The BAER team includes hydrologists, soil scientists, engineers, biologists, silviculturists, range conservationists and archeologists who will evaluate the burned area and prescribe management actions that will protect the land quickly and effectively.
A number of local and state emergency managers have also come together to support locally driven community-based efforts and to initiate mitigation measures that will minimize damage from post-fire floods.
