Data: The Paris Climate Agreement and future sea-level rise from Antarctica; Table: Axios Visuals

Sea-level rise from glaciers and ice sheets is closely tied to the pace and extent of global warming during the next several decades, data from two major new ice melt studies show.

Between the lines: Coastal communities might be able to adapt to the sea-level rise contribution from Antarctica alone through 2100 at lower warming scenarios.

  • However, there would be big increases in that sea-level rise contribution if warming reaches 3° C and an even bigger jump if the highest fossil fuel emissions scenario (RCP 8.5), which looks less likely, comes to fruition.
  • Reminder: The world has already warmed by about 1.2° C, relative to preindustrial levels.

World risks runaway Antarctic ice melt if Paris targets not met

The world runs a growing risk of triggering accelerating and potentially unstoppable sea level rise from the Antarctic ice sheet if greenhouse gas emissions are not strictly curtailed. However, this fate can be avoided if the Paris Agreement's targets are met, according to two new studies published Wednesday.

Why it matters: At stake is the viability of coastal megacities like Shanghai, Manila and New York City, as well as entire nations like the low-lying Maldives. The severity of sea level rise depends largely on the pace and extent of ice melt from the world's two largest ice sheets: Antarctica and Greenland.

Report: ICE deportations drop to record low in April

The number of deportations under U.S. Immigration and Customs Enforcement (ICE) last month dropped to a record low, the Washington Post reports.

Why it matters: His promised 100-day moratorium on deportations was blocked by a federal judge, but the numbers from the Post show Biden's reversal of several ICE directives is having an impact.

NFL to fine unvaccinated players $14K for violating COVID-19 protocols

The NFL will fine unvaccinated players $14,650 if they violate COVID-19 protocols this season, ESPN reports.

The big picture: The rule change comes two days after the NFL announced that postponed games due to coronavirus outbreaks among unvaccinated players or staffers will not be rescheduled and teams responsible for delays will automatically forfeit.
