Our Axios Voices conversation on geoengineering.

There is no comprehensive, multilateral governance of technology to temporarily cool the planet via solar engineering. Scientists have been talking about this technology for five decades, but there has been insufficient policy discussion by governments and non-state actors. This issue is too important to be left to scientists alone.

Big questions: Some argue that ignoring technologies that might lower temperatures would be irresponsible. But the potential benefits of solar engineering claimed by others come with huge challenges and risks – known and unknown. Does research divert attention from what we know works: eliminating emissions and adapting to climate impacts? Would unequal impacts further disadvantage the poorest? Is humanity capable of intentionally engineering such a complex, carefully balanced system? On whose behalf? What global governance would be needed to monitor such a technology?

The bottom line: We face a risky future, and governance is essential to reduce those risks.

Trump to issue at least 100 pardons and commutations before leaving office

President Trump plans to issue at least 100 pardons and commutations on his final full day in office Tuesday, sources familiar with the matter told Axios.

Why it matters: This is a continuation of the president's controversial December spree that saw full pardons granted to more than two dozen people — including former Trump campaign chair Paul Manafort, longtime associate Roger Stone and Charles Kushner, the father of Trump's senior adviser and son-in-law, Jared Kushner.

  • The pardons set to be issued before Trump exits the White House will be a mix of criminal justice ones and pardons for people connected to the president, the sources said.
  • CNN first reported this news.

Schumer's m(aj)ority checklist

Capitalizing on the Georgia runoffs, achieving a 50-50 Senate and launching an impeachment trial are weighty to-dos for getting Joe Biden's administration up and running on Day One.

What to watch: A blend of ceremonies, hearings and legal timelines will come into play on Tuesday and Wednesday so Chuck Schumer can actually claim the Senate majority and propel the new president's agenda.

This is how bad things are for elected officials and others working in a post-insurrection Congress:

  • Rep. Norma Torres (D-Calif.) said she had a panic attack while grocery shopping back home.
  • Rep. Jim McGovern (D-Mass.) said police may also have to be at his constituent meetings.
  • Rep. Adam Kinzinger (R-Ill.) told a podcaster he brought a gun to his office on Capitol Hill on Jan. 6 because he anticipated trouble with the proceedings that day.
