‘Secret City’ Discovered Underneath Greenland’s Ice Sheets

Deep below the thick ice of Greenland lies a labyrinth of tunnels that were once thought to be the safest place on Earth in case of a war.

First created during the Cold War, Project Iceworm saw the US plan to store hundreds of ballistic missiles in a system of tunnels dubbed “Camp Century,” Britain’s the METRO newspaper reported on Wednesday.

At the time, it said, US military chiefs had hoped to launch a nuclear attack on the Soviet Union during the height of Cold War tensions if things escalated.

But less than a decade after it was built, the base was abandoned in 1967 after researchers realized the glacier was moving.

Now, the sprawling sub-zero tunnels have been brought back to attention in the stunning new images.

Alex Gardner, a cryospheric scientist at Nasa’s jet propulsion laboratory said: “We were looking for the bed of the ice and out pops Camp Century. We didn’t know what it was at first. In the new data, individual structures in the secret city are visible in a way that they’ve never been before.”

The underground three-kilometer network of tunnels played host to labs, shops, a cinema, a hospital, and accommodation for hundreds of soldiers.

But the icy Greenland site is not without its dangers – it continues to store nuclear waste.

Assuming the site would remain frozen in perpetuity, the US army removed the nuclear reactor installed on site but allowed waste – equivalent to the mass of 30 Airbus A320 airplanes – to be entombed under the snow, the magazine said.

But other sites around the world – without nuclear waste – could also serve as a safe haven in case of World War 3.

Wood Norton is a tunnel network running deep into the Worcestershire forest, originally bought by the BBC during World War 2 in case of a crisis in London.

Peters Mountain in Virginia, US, serves as one of several secret centers also known as AT&T project offices, which are essential for the US government’s continuity planning.

Further north in the states, Raven Rock Mountain Complex in Pennsylvania is a base that could hold up to 1,400 people.

And Cheyenne Mountain Complex in El Paso County, Colorado, is an underground complex boasting five chambers of reservoirs for fuel and water – and in one section there’s even reportedly an underground lake.

A coalition backed by Google, Stripe and Shopify will spend $1.7 million to buy carbon removal credits from three early stage firms on behalf of the tech giants to help scale up the nascent markets, an executive told Reuters.

The world is expected to need to suck between five and 10 billion tons a year of carbon emissions out of the atmosphere by mid-century to reach its climate goals, yet at the moment most technologies are small scale.

The coalition, called Frontier, is also backed by H&M Group, JPMorgan Chase and Salesforce, among others.

The group, which aggregates demand from its members, will spend $1.7 million to buy credits from US-firm Karbonetiq, Italy-based Limenet and Canadian firm pHathom.

By contracting to buy early, the firms are better able to hire, raise finance and get the technologies off the ground, said Hannah Bebbington, head of deployment at Frontier.

"It allows companies to demonstrate commercial viability," she said.

Frontier's support for these early stage firms, which aim to lock emissions away in the ocean or in rocks and industrial waste, marks its fifth series of commitments.

Frontier, which was set up in 2022, aims to invest at least $1 billion in carbon removal credits between 2022 and 2030. It has already committed $600 million, some on the series of pre-purchases and the bulk on a series of off-take agreements with larger firms. Last week, it agreed to pay $41 million for 116,000 tons from waste biomass firm Arbor.

For oceans, the aim is to increase the alkalinity of the water, helping it to lock away more carbon emissions. This is often done by adding "quicklime", made from limestone.

For the mineralization technologies, meanwhile, projects attempt to speed up the process whereby rocks and industrial waste naturally absorb carbon dioxide, for example by crushing up the material to create a larger surface area.

Bebbington said both technologies had the potential to be impactful because they could be scaled quickly and cheaply.

"We think (they) are extremely compelling from that really cheap at really large scale perspective."
