‘If it’s safe, dump it in Tokyo’ – Pacific Islanders don’t want Fukushima waste water

Guardian 26th April 2021, If it’s safe, dump it in Tokyo. We in the Pacific don’t want Japan’s
nuclear wastewater. To Pacific peoples, who have carried the
disproportionate human cost of nuclearism in our region, this is yet
another act of catastrophic and irreversible trans-boundary harm that our
region has not consented to.

While Japan’s plan is for the water to be
diluted first and discharged over the course of about 30 years, and the
Japanese government has tried its hardest to convince the wider public of
the treated water’s safety through the use of green mascots and backing
from American scientists, Pacific peoples are once again calling it for
what it is: an unjust act.

“We need to remind Japan and other nuclear
states of our Nuclear Free and Independent Pacific movement slogan: if it
is safe, dump it in Tokyo, test it in Paris, and store it in Washington,
but keep our Pacific nuclear-free,” said Motarilavoa Hilda Lini, Vanuatu
stateswoman and veteran activist of the Nuclear Free and Independent
Pacific (NFIP) movement, after Japan’s announcement. “We are people of
the ocean, we must stand up and protect it.”

University of Sheffield researchers do detailed study of radioactive materials inside the wrecked Chernobyl nuclear reactor

Yorkshire Post 26th April 2021, University of Sheffield scientists to help clean up waste from ‘world’s
worst’ nuclear accident. On the 35th anniversary of one of the world’s worst nuclear disasters, new Yorkshire-led research has been published that could help to clean up the most dangerous radioactive materials that still
remain at the site in Chernobyl.

Scientists say the revealing findings – which are the most “detailed results” into the chemical makeup of the
radioactive materials inside the plant’s melted core to date – could ”pave the way” to safely remove hazardous waste from the site and help prevent future nuclear disasters.

Dr Claire Corkhill, the project lead, from the University of Sheffield, stressed the urgency to the research as until now only a very limited number of samples have been analysed by scientists round the world. This is because the most dangerous materials that remain inside Chernobyl are so hazardous, hampering efforts to safely contain or remove the materials from the disaster zone. Dr Corkhill, told The Yorkshire Post: “This is such a big breakthrough because it opens up a world of possibilities to develop a deeper understanding of some of the most dangerous materials that still remain in Chernobyl.

Earth has shifted on its axis due to melting of ice, study says

Earth has shifted on its axis due to melting of ice, study says  https://thebulletin.org/2021/04/earth-has-shifted-on-its-axis-due-to-melting-of-ice-study-says/?utm_source=Newsletter&utm_medium=Email&utm_campaign=MondayNewsletter04262021&utm_content=ClimateChange_AxisTilt_04242021

By Damian Carrington | April 24, 2021Editor’s note: This story was originally published by The Guardian. It appears here as part of the Climate Desk collaboration.

The massive melting of glaciers as a result of global heating has caused marked shifts in the Earth’s axis of rotation since the 1990s, research has shown. It demonstrates the profound impact humans are having on the planet, scientists said.

The planet’s geographic north and south poles are the point where its axis of rotation intersects the surface, but they are not fixed. Changes in how the Earth’s mass is distributed around the planet cause the axis, and therefore the poles, to move.

In the past, only natural factors such as ocean currents and the convection of hot rock in the deep Earth contributed to the drifting position of the poles. But the new research shows that since the 1990s, the loss of hundreds of billions of tons of ice a year into the oceans resulting from the climate crisis has caused the poles to move in new directions.

The scientists found the direction of polar drift shifted from southward to eastward in 1995 and that the average speed of drift from 1995 to 2020 was 17 times faster than from 1981 to 1995.

Since 1980, the position of the poles has moved about 4 meters in distance. “The accelerated decline [in water stored on land] resulting from glacial ice melting is the main driver of the rapid polar drift after the 1990s,” concluded the team, led by Shanshan Deng, from the Institute of Geographic Sciences and Natural Resources Research at the Chinese Academy of Sciences.

Gravity data from the Grace satellite, launched in 2002, had been used to link glacial melting to movements of the pole in 2005 and 2012, both following increases in ice losses. But Deng’s research breaks new ground by extending the link to before the satellite’s launch, showing human activities have been shifting the poles since the 1990s, almost three decades ago.

The research, published in the journal Geophysical Research Letters, showed glacial losses accounted for most of the shift, but it is likely that the pumping up of groundwater also contributed to the movements. Groundwater is stored under land but, once pumped up for drinking or agriculture, most eventually flows to sea, redistributing its weight around the world. In the past 50 years, humanity has removed 18 trillion tons of water from deep underground reservoirs without it being replaced.

Vincent Humphrey, at the University of Zurich, Switzerland, and not involved in the new research said it showed how human activities have redistributed huge amounts of water around the planet: “It tells you how strong this mass change is—it’s so big that it can change the axis of the Earth.” However, the movement of the Earth’s axis is not large enough to affect daily life, he said: It could change the length of a day, but only by milliseconds.

Jonathan Overpeck, a professor at the University of Arizona, told the Guardian previously that changes to the Earth’s axis highlighted “how real and profoundly large an impact humans are having on the planet”.

Some scientists argue that the scale of this impact means a new geological epoch – the Anthropocene—needs to be declared. Since the mid-20th century, there has been a marked acceleration of carbon dioxide emissions and sea level rise, the destruction of wildlife and the transformation of land by farming, deforestation, and development.
