Climate costs bolt upward. #auspol #science

jpratt27

President-elect Donald Trump stops taking climate change into account when making federal energy policy, he’ll do so just as a leading projection of climate-related costs bolts upward.

William Nordhaus of Yale University is a central figure in the study of climate change and economics. In the early 1990s he developed what became the leading computer model for studying the effects of warming on the global economy. The Dynamic Integrated model of Climate & the Economy (DICE) has long given resource economists, students, and policymakers an opportunity to test how different scenarios might lead to quite different future climates.
Nordhaus recently updated DICE. He published results of an early test-drive of it this week in a National Bureau of Economic Research working paper, titled “Projections and Uncertainties About Climate Change in an Era of Minimal Climate Policies.”
Readers of recent headlines might be forgiven for assuming the “era of minimal climate…

A Marine Food Web Bioaccumulation model for Cesium 137 in the Pacific Northwest

whale3-e1326638481501.jpg

 

From November 2014

Abstract

The Fukushima nuclear accident on 11 March 2011 emerged as a global threat to the conservation of the Pacific Ocean, human health, and marine biodiversity. On April 11 (2011), the Fukushima nuclear plant reached the severity level 7, equivalent to that of the 1986-Chernobyl nuclear disaster. This accident was defined by the International Atomic Energy Agency as “a major release of radioactive material with widespread health and environmental effects requiring implementation of planned and extended countermeasures”.

Despite the looming threat of radiation, there has been scant attention and inadequate radiation monitoring. This is unfortunate, as the potential radioactive contamination of seafoods through bioaccumulation of radioisotopes (i.e. 137Cs) in marine and coastal food webs are issues of major concern for the public health of coastal communities. While releases of 137Cs into the Pacific after the Fukushima nuclear accident are subject to high degree of dilution in the ocean, 137Cs activities are also prone to concentrate in marine food-webs.

With the aim to track the long term fate and bioaccumulation of 137Cs in marine organisms of the Northwest Pacific, we assessed the bioaccumulation potential of 137Cs in a North West Pacific foodweb by developing, applying and testing a simulation time dependent bioaccumulation model in a marine mammalian food web that includes fish-eating resident killer whales (Orcinus orca) as the apex predator.

The model outcomes showed that 137Cs can be expected to bioaccumulate gradually over time in the food web as demonstrated through the use of the slope of the trophic magnification factor (TMF) for 137Cs, which was significantly higher than one (TMF > 1.0; p < 0.0001), ranging from 5.0 at 365 days of simulation to 30 at 10,950 days.

From 1 year to 30 years of simulation, the 137Cs activities predicted in the male killer whale were 6.0 to 182 times 137Cs activities in its major prey (Chinook salmon, Oncorhynchus tshawytscha).

Bioaccumulation of 137Cs was characterized by slow uptake and elimination rates in upper trophic level organisms and dominance of dietary consumption in the uptake of 137CS.

This modeling work showed that in addition to the ocean dilution of 137Cs, a magnification of this radionuclide takes place in the marine food web over time.

Block Trump. Declare World War on Global Warming and Other Human Impacts on Nature

Our Problem

desert-earth Earth could join Mars as a dry, lifeless derelict.

Scientists report that growth and spread of humanity together with rising global temperature are causing declining biodiversity, rising seas, growing storms, intensifying drought, spreading disease, and much more. The reports, made by observers all over the world, are like the thunder ahead of a storm that threatens the safety of our families, our friends, our civilization, and all life on our planet. We know it’s coming. Without a massive effort by the people of the world, the storm will grow until terrible destruction ruins our planet. We and all other life may be lost.

Donald Trump’s pre-inauguration statements and cabinet choices make it clear that he will add to global warming and every other negative human impact on Earth.

The Earth continues turning, but if…

On the Unique DNA Damage Done by Ionizing Radiation-Nuclear Materials (and on Metting, Hultgren, et.al. Misleading the US Congress in this Matter)

Mining Awareness +

Clustered DNA damage is considered a signature of ionizing radiation: “clustered DNA damage sites, which may be considered as a signature of ionising radiation, underlie the deleterious biological consequences of ionising radiation…ionising radiation creates significant levels of clustered DNA damage, including complex double-strand breaks (DSB)” See: “Biological Consequences of Radiation-induced DNA Damage: Relevance to Radiotherapy“, by M.E. Lomax et. al. Clinical Oncology 25 (2013) 578-585

The formation of clustered damage distinguishes ionising radiation-induced damage from normal endogenous damage“. https://cordis.europa.eu/pub/fp5-euratom/docs/non_dsb_lesions_projrep_en.pdf (See more details further below, after political commentary.)

99 Ways to Fight Trump

GarryRogers Nature Conservation

GR:  Trump is the mouth of the oligarchy. Corrupted by corporate money, Congress has turned against us and now they’ve found someone to tell them it’s okay. We must stop Trump’s attempts, but more than just Trump, we must act to stop wildlife extinctions and global warming.  Michael Moore says that we need to form small action groups composed of family, friends, or neighbors that share news and action ideas, and he says he believes things will be worse than we expect. Figures. In the list below, number one definitely belongs at the top of the list. Here’s a taste of the list:

  1. Don’t just complain to your friends, let Congress know how you feel. Often. When you disagree with them AND when you agree. Write Reps here & Senators here.
  2. Tell state legislatures it’s time to get rid of the Electoral College. We can make it happen, and we…

NRA: Ice wall effects ‘limited’ at Fukushima nuclear plant

27 dec 2016.jpg

Citing “limited, if any effects,” the Nuclear Regulation Authority said a highly touted “frozen soil wall” should be relegated to a secondary role in reducing contaminated groundwater at the Fukushima No. 1 nuclear plant.

The government spent 34.5 billion yen ($292 million) to build the underground ice wall to prevent groundwater from mixing with radioactive water in four reactor buildings at the crippled plant.

But the NRA, Japan’s nuclear watchdog, concluded on Dec. 26 that the wall has been ineffective in diverting the water away from the buildings. It said that despite the low rainfall over the past several months, the amount of groundwater pumped up through wells outside the frozen wall on the seaside is still well above the reduction target.

It urged the plant operator, Tokyo Electric Power Co., to tackle the groundwater problem primarily with pumps, not the ice wall.

In response, TEPCO at the meeting said that by next autumn, it will double its capacity to pump up groundwater from the current 800 tons a day.

About 400 tons of groundwater enters the damaged reactor buildings each day and mixes with highly radioactive water used to cool melted nuclear fuel.

The ice wall project, compiled by the industry ministry in May 2013, was seen as a fundamental solution to this problem that has hampered TEPCO’s cleanup efforts since the triple meltdown in March 2011.

Some 1,568 frozen ducts were inserted 30 meters deep into the ground to circulate a liquid at 30 degrees below zero. The freezing process was supposed to have created a solid wall of ice that could block the groundwater.

TEPCO began freezing the wall on the seaside in March. It announced in the middle of October that the temperature at all measuring points in that area was below zero.

Before the frozen wall project, TEPCO had to pump up about 300 tons of contaminated water a day. The daily volume dropped to about 130 tons in recent weeks, but it was still well beyond the target of 70 tons.

Still, TEPCO boasted about the effectiveness of the ice wall at the meeting with the NRA on Dec. 26, saying, “We are seeing certain results.”

The NRA, however, said the results are limited at best.

Toyoshi Fuketa, an NRA commissioner, already warned TEPCO in October that it cannot expect the ice wall to be highly effective in containing the groundwater.

Pumping up groundwater through wells should be the main player because it can reliably control the groundwater level,” Fuketa said at that time. “The ice wall will play a supporting role.”

That sentiment was echoed at the Dec. 26 meeting.

However, the NRA approved the utility’s plan to begin freezing dirt for a wall on the mountain side of the nuclear plant.

The NRA was previously concerned about risks posed by the new ice wall. If it totally blocked groundwater from the mountain side, the water level within the frozen soil near the reactors could become too low, allowing highly contaminated water inside the reactor buildings to flow out more rapidly.

The NRA urged TEPCO to delay work on the mountain side until the ice wall on the seaside portion proved effective.

But it reversed its stance, saying a sharp drop in the groundwater level is unlikely based on the ineffectiveness of the existing ice wall.

The frozen wall on the mountain side will not be able to block groundwater because the wall on the seaside was also unable to do so,” Fuketa said. “It will not be very dangerous to freeze the wall on the mountain side as long as the work is carried out carefully.”

TEPCO will start the work to freeze the ducts at five sections as early as next year.

Masashi Kamon, professor emeritus of geotechniques at Kyoto University, expressed skepticism about continuing the ice wall project without a full scrutiny of the underground conditions.

Soil around the tunnels for underground pipes must be hard to freeze,” he said. “TEPCO should find out the conditions of the very bottom of the ice wall by drilling at least one section. It is questionable to continue with the project without a review.”
