White House Endorses Unlimited Liability Cap For Oil Spillers

First Posted: 06- 7-10 06:00 PM   |   Updated: 06- 7-10 06:18 PM

Democrats in Congress and officials in the White House are making yet another major push to pass legislation to make the liability for oil companies involved in damaging spills unlimited.
On Monday evening, the White House confirmed that it favors the most recent piece of legislation that would drop any numerical ceiling to the amount of money an oil company like BP would have to pay for economic damages caused by a spill. Currently, the cap is $75 million. cont.....

LMRP on BOP חדשות ישנות מהמפרץ

לפני יומיים המחבר שידוע בכינויו LMRP הורכב בראש ה-BOP לאחר מבצע מורכב של של חיתוך המגביה וצינור המקדח בתוכו המבצע עבר בהצלחה והמיתקן מעביר כמויות של נפט וגז לאונית הקידוח מעליו כמה? שאלה מצויינת שאין לה תשובה בהודעות של bp. במקביל עומדות להתחיל העבודות לגשור איים ויצירת מחסום חול מסביב לדלתה של המיסיסיפי. ישנה מחלוקת בקשר לרעיון
BOP המתקן שמחובר לראש הבאר ואמור היה למנוע התפרצות של נפט וגז אבל כשל כידוע
LMRP Containment Operation Deployed
Release date: 04 June 2010
http://www.bp.com/genericarticle.do?categoryId=2012968&contentId=7062653

BP announced today that oil and gas is being received onboard the Discoverer Enterprise following the successful placement of a containment cap on top of the Deepwater Horizon's failed blow-out preventer (BOP). This follows the cutting and removal of the riser pipe from the top of the BOP's lower marine riser package (LMRP).
It is expected to take one or more days for flow rates of oil and gas to stabilize and it is not possible at this stage to estimate how much oil and gas will be captured by this containment system.
All of these operations are complex, involve risks and uncertainties, and have to be carried out by remotely operated vehicles (ROVs) at 5,000 feet under water. Systems such as the LMRP containment cap never before have been deployed at these depths and conditions. The containment system's efficiency, continued operation, and ability to contain the oil and gas cannot be assured.
Preparations continue for the planned enhancements to the containment system as announced on June 1. Work continues on the first relief well, which started on May 2, and the second relief well, which started on May 16. Both wells are still estimated to take around three months to complete from commencement of drilling.
Louisiana Begins Controversial Engineering to Ward Off Oil Spill
Erik Stokstad Science 4 June 2010:
Regardless of when BP finally manages to stop its undersea gusherfrom the Deepwater Horizon, a massive slick will likely remainin the Gulf of Mexico for some time. With public officials desperatefor action, the magnitude of the disaster—the largestoil spill in U.S. history—has inspired an unprecedentedand untested idea for combating it: an extensive sand trap.But scientists are dubious about the project's chance of successand say it could even jeopardize long-term restoration of Louisiana'swetlands, which have been disappearing for decades.

Impacts of Climate Change on  Australian Marine Life 
Part A: Executive Summary

CSIRO Marine and Atmospheric Research

6.4 Mangroves 
Ecology 
Mangrove communities are diverse assemblages of trees and shrubs that are found fringing 
much of the tropical and sub-tropical coastline of Australia in sheltered areas, with the most 
extensive communities found in the tropics. The mangrove flora of Australia is one of the most 
diverse globally and these are highly productive systems. Mangroves act as an important buffer 
between land and sea, filtering terrestrial discharge, decreasing sediment loading of coastal 
waters and maintaining the integrity of coastlines. They are also valuable for their role in 
nutrient and carbon cycling. Mangroves act as a nursery and breeding habitat for marine species 
such as fish, crabs and prawns, including many commercially valuable species, and they also 
support a variety of terrestrial species such as bird populations.  

Implications 
Mangroves are under threat from coastal development, river catchment modification and 
pollution. While adapted to cope with salty conditions, mangroves thrive in areas where there is 
plentiful input of fresh water. Sea level rise is now considered a major threat to mangroves; they 
grow on shorelines with a low profile, thus, a small rise in sea level could inundate large areas 
of mangroves. Increases in atmospheric CO2 may enhance mangrove growth, but this will 
depend on other factors such as nutrient availability and salinity levels. Given the role of 
mangroves in coastal systems, conservation of mangroves should be considered a priority 
management strategy in response to climate change threats

warmest snow less april  כיסויי השלג הנמוך ביותר באפריל החם ביותר

אפריל האחרון היה החם ביותר מאז שיש מדידות
ובמקביל ולא מאוד מפתיע כסוי השלג באמריקה הצפונית היה הנמוך ביותר מאז שהתחילו המדידות

Winter 2009-2010 was much colder than normal for the United States, and it delivered a string of record-breaking snowstorms that began on the winter solstice.
The snow and cold didn’t linger far into the spring, however. By the end of April, North American snow cover had retreated to the lowest extent in the 1967–2010 record, according to the National Oceanic and Atmospheric Administration’sApril 2010 State of the Climate Report. This map shows percent snow cover across North America in April 2010 based on observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Percent snow cover ranges from just above zero (light blue) to 100 percent (white). Land areas with no detectable snow cover during the month are gray.
According to NOAA, “Across North America, snow cover for April 2010 was 2.2 million square kilometers below average—the lowest April snow cover extent since satellite records began in 1967 and the largest negative anomaly to occur in the 521 months that satellite measurements are available.” Unusual warmth descended on North America in April, leading to both low snowfall amounts and rapid melt of existing snow.

May 17, 2010
Each month NOAA’s National Climatic Data Center (NCDC) releases two assessments, one national and one global, of the previous month’s climate. These reports include information on the temperature and precipitation levels experienced nationally and globally, providing useful information about these important climate variables in historical perspective. The reports also chronicle any significant weather and climate-related events that occurred during the month.  This trusted source of information is used globally by industry and business, government agencies, academia, and members of the public to help inform decision making.

Summary Figures from the Global Report
The global report is a monthly snapshot of the climate system around the globe that informs the public of the current state of the global climate and helps planners, academics and sector users factor the climate’s current state and recent trends into their decision making. The report details the average global land temperature, the average global ocean temperature, and the combined average of the two. Instead of using raw temperatures, the report presents temperature anomalies, which means the difference from average temperatures for any given area over a period of time. Using anomalies allows for a more accurate understanding of temperature trends over space and time, even with some fluctuations in data availability (see additional information below).
April 2010 Global Temperature Anomalies

This figure depicts all the global surface temperature anomalies for the month of April from 1880 to 2010.
Highlights:
  • The global land and ocean temperature during April 2010 was the warmest on record, surpassing the previous record set in 1998.
  • The warmest anomalies during April 2010 occurred in southern Asia, northern Africa, the north central and northeastern U.S., Canada, Europe, and parts of northern Russia.
  • Cooler-than-average conditions prevailed across Argentina, Mongolia, eastern and southern Russia, and most of China.
  • This was the 34th consecutive April with average global surface (land + ocean) temperatures above the 20th century average.
    • The last April with below average temperatures occurred in 1976.
  • April 2010 was the 302nd consecutive month with average global surface (land + ocean) temperature above the 20th century average.
    • The last month with an average global surface (land + ocean) temperature below the 20th century average was February 1985.
  • Although temperature anomalies across the equatorial Pacific Ocean remained above 0.5°C (0.9°F), El Niño weakened during April 2010. According to NOAA's Climate Prediction Center (CPC), a transition to El Niño Southern Oscillation (ENSO) neutral conditions is expected by June 2010 and to continue into the Northern Hemisphere summer 2010.
  • According to Beijing Climate Center, China experienced its coolest April since 1961. Liaoning, Jilin, and Shandong had their coolest April on record. Hebei, Anhui, and Jiangsu had their second coolest April since records began in 1951.
  • Based on NOAA satellite observations, snow cover extent was the fourth-lowest (fourth-smallest snow cover footprint) on record (since 1967), and below the 1967-2010 average for the Northern Hemisphere, for the seventh consecutive April. Warmer-than-normal conditions over North America, Europe, and parts of Russia contributed to the small snow footprint. These data are compiled at the Rutgers Snow Laboratory, a NOAA-sponsored facility.
  • The North American snow cover extent for the month was the smallest on record for April. It was also the largest negative anomaly, meaning distance below the long-term average, on record for any month.
    • The Northern Hemisphere land-and-ocean temperature were the warmest April on record,
    • The Southern Hemisphere land-and-ocean temperature during April 2010 was second warmest, behind 1998.
    • The tropics (20˚N-20˚S) land-and-ocean temperature tied with 1998 as the warmest April on record.

  • Temperature anomalies for the first four months of the year were anomalously warm over much of the world’s surface, especially so in Canada, northern Africa, South Asia and the vast majority of the tropics.
  • Cooler-than-average conditions prevailed across the higher-latitude southern oceans, the Gulf of Alaska, along the western South American coast, Mongolia, northern China, the southern U.S., northern Mexico, and much of Europe and Russia.
  • The Northern Hemisphere land and ocean temperature during January-April 2010 was the third warmest on record.
  • The Southern Hemisphere land and ocean temperature were second warmest such period, behind 1998.
  • The tropics (20˚N-20˚S) land and ocean temperature during January-April 2010 were also the second warmest on record, behind 1998.
  • January-April 2010 global average temperatures were the warmest on record.
  • The global land surface temperature during January-April 2010 ranked as the third warmest on record, behind 2007 (warmest) and 2002 (second warmest).
  • The global ocean surface temperature during January-April 2010 was second warmest, behind 1998.
  • January-April 2010 was the 34th consecutive year with above average temperatures. The last January-April with below average temperatures occurred in 1976.

ROBERT, La. — BP's attempt to plug the Gulf oil leak with mud and cement has failed, yet another setback in the company's attempt to stop the crude from further fouling waters, wildlife and marshland. The gusher has spilled between 18 million and 40 million gallons of oil into the sea over the past five weeks.

Experts Propose Plugging Oil Leak with BP Executives

Submerging Execs Could Be 'Win-Win'

תרגום בהמשך


WASHINGTON (The Borowitz Report) – At a conference of oil leak experts in Washington today, attendees proposed plugging the massive oil leak in the Gulf of Mexico with executives of BP, the company responsible for the catastrophic spill.
“We’ve tried containment domes, rubber tires, and even golf balls,” said William Cathermeyer of the National Oil Leakage Institute, a leading consultancy in the field of oil leaks.  “Now it’s time to shove some BP executives down there and hope for the best.”
Submerging the oil company executives thousands of feet below the ocean’s surface could be a “win-win” situation, Mr. Cathermeyer said.
“Best-case scenario, they plug the leak,” he said.  “And at the very least, they’ll shut the fuck up.”
But even as the oil leak experts proposed their unorthodox solution, environmental expert Marilyn Sufranski warned of the possible negative consequences of plugging the oil leak with BP executives.
“The Gulf of Mexico is slimy enough already,” she said.  More here.
