In 1966, the Army abandoned Camp Century, leaving hundreds of tons of waste inside the ice sheet. Today, the crushed and abandoned camp lies more than 100 feet (30 meters) below the ice sheet surface. But as the climate warms and the ice melts, that waste will resurface: millions of gallons of frozen sewage, asbestos-wrapped pipes, toxic lead paint and carcinogenic PCBs.

Who will clean up the mess and at what cost is an open question.

Greenland remains a tough place to turn a profit

In the past, the American focus in Greenland was on short-term gains with little regard for the future. Abandoned bases, scattered around the island today and in need of cleanup, are one example. Peary’s disregard of the lives of local Greenlanders is another.

History shows that many of the fanciful ideas for Greenland failed because they showed little consideration of the island’s isolation, harsh climate and dynamic ice sheet.

Trump’s demands for American control of the island as a source of wealth and U.S. security are similarly shortsighted. In today’s rapidly warming climate, disregarding the dramatic effects of climate change in Greenland can doom projects to failure as Arctic temperatures climb.

Recent floods, fed by Greenland’s melting ice sheet, have swept away bridges that had stood for half a century. The permafrost that underlies the island is rapidly thawing and destabilizing infrastructure, including the critical radar installation and runway at Thule, renamed Pituffik Space Base in 2022. The island’s mountain sides are crashing into the sea as the ice holding them together melts.

The U.S. and Denmark have conducted geological surveys in Greenland and pinpointed deposits of critical minerals along the rocky, exposed coasts. However, most of the mining so far has been limited to cryolite and some small-scale extraction of lead, iron, copper and zinc. Today, only one small mine extracting the mineral anorthosite, which is useful for its aluminum and silica, is running.

It’s the ice that matters

The greatest value of Greenland for humanity is not its strategic location or potential mineral resources, but its ice. https://www.youtube.com/embed/9lnP0Rjb2E0?wmode=transparent&start=0 A NASA animation of satellite data shows Greenland’s ice sheet mass losses between 2002 and 2023, measured in meters of water equivalent in the ice.

If human activities continue to heat the planet, melting Greenland’s ice sheet, sea level will rise until the ice is gone. Losing even part of the ice sheet, which holds enough water to raise global sea level 24 feet in all, would have disastrous effects for coastal cities and island nations around the world.

That’s big-time global insecurity. The most forward-looking strategy is to protect Greenland’s ice sheet rather than plundering a remote Arctic island while ramping up fossil fuel production and accelerating climate change around the world.

New Year, new hope for Bitcoin. After several months of sputtering, Bitcoin is back on the rise. On Wednesday, the original cryptocurrency surpassed $97,000 for the first time in two months and is up more than 6% in the last week. 

“We’d rather have no bill than a bad bill,” Armstrong wrote, outlining several blockchain sector critiques, including a key battle with the banking industry over offering rewards for stablecoin holdings. “Hopefully we can all get to a better draft.” 

The legislation, which focuses on market structure issues such as supervisory divisions between different federal agencies, has long been a priority for the crypto industry. The bill would address thorny questions that led to bruising lawsuits under previous administrations, including how to classify and regulate different types of cryptocurrencies. 

After helping elect a wave of pro-blockchain candidates fueled by millions in campaign donations, the crypto industry notched a major win over the summer with the passage of the Genius Act, which established a regulatory framework for stablecoins, or a type of dollar-backed cryptocurrency. But market structure has proven trickier, especially after the banking lobby pushed back against provisions in the Genius Act that allows companies to offer customers yield on their stablecoin holdings, similar to savings accounts. 

After the House of Representatives advanced their version of the market structure legislation, called the Clarity Act, in July, the Senate delayed in taking up the bill. But with the Senate Banking Committee finally set to debate amendments on Thursday morning in the markup process, arguments over the issue of yield, as well as conflict of interest ethics provisions targeted at the Trump administration, could stymie the bill’s progress. 

“There’s a real chance this could blow up in committee,” one crypto lobbyist told Fortune, speaking on the condition of anonymity to discuss sensitive industry dynamics. “People are pretty fired up here.” 

Lack of clarity

For many in the crypto industry, the success of the stablecoin-focused Genius Act over the summer was just an appetizer to the main course: wide-ranging market structure legislation that would finally grant legitimacy to the renegade sector. But after years of fierce debate, the product coming out of the Senate might be worse than no bill at all. 

The most significant wedge issue going into Thursday remains the battle over stablecoin yields. The bank lobby has argued that the Genius Act effectively created a loophole, preventing stablecoin issuers themselves from offering yield to users, but allowing partners and third parties to provide rewards. Those programs have been key to many crypto companies, such as Coinbase, which reported $355 million in stablecoin-related revenue in the third quarter of 2025 and offers yields to holders of its stablecoin, USDC. Bank lobbyists have argued that this could threaten the U.S. financial system by suctioning money out of bank deposits. 

A bipartisan group of senators has offered a compromise in the Clarity Act, which would allow crypto companies to offer yield for stablecoin-related transactions, similar to credit cards, as well as other activity. But it remained unclear whether Coinbase, one of the most outspoken and deepest-pocketed crypto figures in Washington, would support the agreement, with Armstrong’s Wednesday post seeming to indicate it would take a hard-line approach. 

“It’s still very much in negotiations right now,” said Ron Hammond, who serves as head of policy at the crypto trading firm Wintermute. “But it’s crypto and there’s always last-second drama, and so it seems to be one of the wedges here.” 

Another debate pushed by Democrats is language that would prevent politicians, including the President, from profiting off of crypto holdings or interest. The issue has become a lightning rod due to the Trump family’s deep entanglement with the crypto industry, including its digital asset platform World Liberty Financial, which recently applied for a federal bank license. But Republicans have strongly pushed back against the possibility, with Senate Banking Committee Chair Tim Scott (R-S.C.) telling CoinDesk on Wednesday that ethics provisions don’t belong in the Clarity Act. 

But a letter sent to Scott and Ranking Member Elizabeth Warren (D-Mass.) from a number of nonprofit watchdog groups, obtained by Fortune, describes the lack of provisions in the proposed bill addressing governmental conflicts of interest as “deeply concerning.” 

If Democrats such as Ruben Gallego (D-Ariz.), who has referred to an ethics provision as a “red line,” pull their support, the bill could be stuck in committee, which needs a simple majority vote, though Republicans hold the edge. 

The lobbyist who spoke on the condition of anonymity lamented that the bill has lurched to the left in an effort to gain bipartisan support, including through additional provisions that would regulate DeFi, or decentralized finance, as well as the listing process for crypto tokens and oversight responsibilities handed to the Securities and Exchange Commission. “They’ve lost their north star,” the lobbyist told Fortune.
