“The long-term nature of OCS oil and gas development, such that production on a lease can continue for decades makes consideration of future climate pathways relevant to the Secretary’s determinations with respect to how the OCS leasing program best meets the Nation’s energy needs.“
Basing offshore leasing decisions on “future climate pathways” is a high risk strategy that may be inconsistent with the recent SCOTUS decision in West Virginia vs. EPA. A planned or phased shutdown of the offshore oil and gas program would dramatically increase economic and security risks, and has not been authorized by legislation.
“The American people have moved on. The President himself has declared ‘the Pandemic is over.’ Yet, we continue holding fast to an outdated mandate, purging hundreds of dedicated sailors, even though we struggle to meet our recruiting goals. It is now time to take a pause, reevaluate, and assess what this is costing readiness, the taxpayer, and the public perception of how we treat our people,” he wrote in the letter.
Sept 30 (Reuters) – The ruptures on the Nord Stream natural gas pipeline system under the Baltic Sea have led to what is likely the biggest single release of climate-damaging methane ever recorded, the United Nations Environment Programme said on Friday.
“This is really bad, most likely the largest emission event ever detected,” Manfredi Caltagirone, head of the IMEO for UNEP, told Reuters. “This is not helpful in a moment when we absolutely need to reduce emissions.”
Researchers at GHGSat, which uses satellites to monitor methane emissions, estimated the leak rate from one of four rupture points was 22,920 kilograms per hour. That is equivalent to burning about 630,000 pounds of coal every hour, GHGSat said in a statement.
The Nord Stream methane release, while puzzling and rather frightening given the potential for escalating international tensions, was not an environmental disaster or even a major environmental setback.
Some perspective:
estimate for the main Nord Stream leak (likely the maximum or near-maximum rate) = 22,930 kg/hr
22,930 kg/h = 550,320 kg/day = 550.320 x 106g/day
total methane source forNorth American coastal waters (NASEM, Oil in the Sea, p. 63) = 4 – 20 Tg/yr
10 Tg/yr (i.e. 10 x 1012 g/yr) = 0.027 x 1012 g/day = 27000 x 106g/day
This is ~50 times the temporary (maximum?) daily rate for the Nord Stream leak
The National Academies have released Oil in the Sea IV, which updates estimates of oil entering North American seas. This is the third update since the publication of Oil in the Sea in 1985.
The updated inputs and seeps summary tables are pasted below. Some comments:
The Oil in the Sea reports are important in that they provide perspective on natural inputs and those associated with man’s activities. The estimates generate informed discussion about the relative significance of the various inputs.
The estimate for land-based sources, which far outweigh all other sources, increased dramatically from the previous report.
The oil seepage estimate was reduced by 37.5%, owing to methodology.
The difference between the itemized seepage total in Table 3.2 (109,000 mta) and the seepage total in Table 3.1 (100,000 mta) is not explained.
The estimate for platform spills (excluding Macondo and the MC-20 seepage) was significantly and inexplicably increased from the previous report, and is well above what BSEE data indicate for that period. No data or justification are provided.
The statement (p. 58) that “spills occurred more frequently in offshore waters than nearshore waters” is puzzling and unsubstantiated.
-The government has decided to implement measures to strengthen preparedness related to infrastructure, land facilities and installations on the Norwegian continental shelf.
-Part of the background for the increased preparedness is reports of increased drone activity on the Norwegian continental shelf that we have seen in recent weeks. It concerns drones of various sizes. Activity has been increasing, especially in September.
Circumstances where drones have violated safety zones around facilities are now being investigated by the police. We refer to Sør-Vest Police District for questions about this.
-On Tuesday, it became known that the Nord Stream 1 and 2 gas pipelines were damaged, probably due to sabotage. The Norwegian Petroleum Safety Authority does not want to speculate on who is behind it, or other circumstances related to the incident.
-On Thursday 29 September, we invited the parties in the oil and gas industry to an extraordinary meeting in the Security Forum to discuss the ongoing events
Germany’s navy is contributing to the investigation into the Nord Stream 1 and 2 gas pipeline leaks, said Defence Minister Christine Lambrecht, who added that the situation must be clarified and those responsible must be identified quickly.
Russia’s FSB security service is investigating the damage sustained by the Nord Stream gas pipelines under the Baltic Sea as “international terrorism”, the Interfax news agency cited the general prosecutor’s office as saying on Wednesday.
