A rare, long-term record of Greenland ice melt reveals the world's largest island shed ice nearly 6 times faster in the past decade when compared to the 1980s, an increase that is already contributing to sea level rise and altered ocean currents, a new study finds.

Why it matters: Greenland's fate will help determine the future viability of coastal megacities around the world, from New York to Shanghai, as sea levels rise in response to added freshwater.

What they did: For the study, published in Proceedings of the National Academy of Sciences, researchers compared data on the discharge of glacial ice into the ocean from 260 glaciers with the accumulation of snow in the interior of the island, as gathered from regional climate models.

What they found: The acceleration of Greenland's melt, which is happening due to warming air and ocean temperatures, has contributed nearly 14 millimeters in global sea level rise since 1972.

  • Half of this increase has occurred in just the past 8 years.
  • The Greenland Ice Sheet shed mass every year since 1998, even when the summer was relatively cool and inland snowfall was above average.
  • Relatively cool summers can slow surface melt, but don't stop fast-moving glaciers from flowing into the sea.
  • The regions contributing the most to ice loss so far are Northwest and Southeastern Greenland.
  • Study co-author Eric Rignot warns future ice loss could come from northern Greenland, which is seeing rapid changes. "We have time to prepare and re-adjust, but time is running out to avoid massive problems near the end of the century," he tells Axios.

What they're saying: Richard Alley, a glacier expert at Penn State University who was not involved in the new study, says the research is especially useful for laying out year-to-year variability in snowfall and mass loss.

"The big picture, from this work and much earlier work, remains clear: with warming, the increase in mass loss from surface melting has exceeded the increase in snowfall, causing net mass loss."

Biden taps ex-FDA chief to lead Operation Warp Speed amid rollout of COVID plan

President-elect Joe Biden has picked former FDA chief David Kessler to lead Operation Warp Speed, a day after unveiling a nearly $2 trillion pandemic relief plan that includes $400 billion for directly combatting the virus.

Why it matters: Biden's transition team said Kessler has been advising the president-elect since the beginning of the pandemic, and hopes his involvement will help accelerate vaccination, the New York Times reports. Operation Warp Speed's current director, Moncef Slaoui, will stay on as a consultant.

The case of the missing relief money

A chunk of stimulus payments is missing in action, thanks to a mix up that put as many as 13 million checks into invalid bank accounts.

Why it matters: The IRS (by law) was supposed to get all payments out by Friday. Now the onus could shift to Americans to claim the money on their tax refund — further delaying relief to struggling, lower-income Americans.

The post-Trump GOP, gutted

Republicans will emerge from the Trump era gutted financially, institutionally and structurally.

The big picture: The losses are stark and substantial.
