Yesterday marked 25 years since the UN's Framework Convention on Climate Change entered into force.

Why it matters: The deal struck in Rio de Janeiro laid the foundation for negotiations — lots of negotiations — that ultimately produced the 2015 Paris climate agreement.

The big picture: Assessing the whole UNFCCC is more than I'll bite off here. But few would argue that the ambition in Rio is translating into policy steps anywhere near commensurate with the problem.

  • The treaty called for "stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic human-induced interference with the climate system."

By the numbers: The average concentration of atmospheric carbon dioxide in 1994 was 359 parts per million, per National Oceanic and Atmospheric Administration records.

  • Last year the average was 409 ppm, and now it's even higher.
  • 2018 was the 4th-warmest year in modern temperature records that date back to the late 1800s, per NOAA.
  • The last 5 years comprise the 5 warmest on record, according to multiple datasets, and 9 of the top 10 have occurred since 2005.
  • Global CO2 emissions rose in 2017 and 2018, ending a 3-year plateau.

But, but, but: Diplomacy and negotiations under the UNFCCC have also led to greater global collaboration on confronting climate change and at least agreeing to what the goals should be.

The Paris deal aims to prevent global temperatures from rising 2°C above pre-industrial levels, with an aspirational target of holding the rise to 1.5°C.

  • That would require extremely steep emissions cuts in the coming years and decades, and right now hitting even the 2°C target looks unlikely.
  • However, the structure of the non-binding Paris deal aims for countries lay out more ambitious emissions plans.

What they're saying: Patricia Espinosa, the top UN climate official, said in a statement marking the birthday that there have been successes and disappointments.

  • "We have the Paris Agreement, and we have the guidelines strengthening that agreement. What we need now are results," she said, calling for more ambition and action to stabilize temperatures.

The bottom line: Major studies conclude that global warming is already having harmful effects worldwide that are expected to worsen as temperatures rise.

Pelosi calls raising the debt ceiling a bipartisan responsibility

House Speaker Nancy Pelosi (D-Calif.) issued a "dear colleague" statement Sunday evening, calling on Congress to act in a bipartisan manner to raise the nation's debt ceiling.

Why it matters: Congress is fast approaching an October deadline to raise the nation's debt ceiling and avoid a government shutdown. But the issue has become a thorny partisan stand-off.

Beto not even best Dem against Abbott

Actor Matthew McConaughey’s nine-point lead in a theoretical matchup against Greg Abbott shows just how vulnerable the hard-right Texas governor could be in a general election.

Why it matters: Abbott has won conservative accolades for his abortion, mask and vaccine bans. Axios reported Sunday that former Rep. Beto O’Rourke is preparing to announce a gubernatorial challenge — but a recent poll shows he’s not even the most popular Democrat in the state.

Delayed maps upend midterm campaigns

Midterm candidates are panicking about how the congressional maps will ultimately be drawn, with several strategists telling Axios campaigns are in limbo.

Why it matters: Candidates are unsure if the district they're targeting will remain intact or be reshaped by the process. The uncertainty is especially vexing to Democrats, who are vying to maintain their narrow margin in the House.
