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.

The High Ambition Coalition's priorities for the Glasgow climate summit

A coalition to watch at the upcoming Glasgow climate summit is made up of some of the most at-risk countries to climate change that don't traditionally wield much power on the global stage, along with some other nations, like Norway, which have ambitious climate targets.

Why it matters: The power of these countries' moral authority on climate change — their very existence is threatened by sea level rise — helped them play a vital role in securing the Paris Agreement in 2015.

Arizona governor sues Biden administration over COVID funds tied to mandates

Arizona Gov. Doug Ducey (R) filed a lawsuit Friday against the Biden administration for ordering the state to stop allocating federal COVID relief funds to schools that don't comply with public health recommendations such as masking, the Arizona Republic reports.

Why it matters: The Treasury Department said last week that the state would have to pay back the money if Ducey does not redesignate the $173 million programs to ensure they don't "undermine efforts to stop the spread of COVID-19."
