13% of nearly 900 cities tracked by the nonprofit CDP get a top rating on climate change action — a fraction of the total population, but roughly double the number of cities on the organization's 2018 list.

Why it matters: Cities create more than 60% of the world's greenhouse gas emissions and consume 78% of the world’s energy. The 105 cities who received an "A" rating from CDP represent a combined population of 170 million.

Where it stands: Big cities in mostly developed parts of the world — including Europe, North America and Australia — dominate CDP's "A List" for taking steps to reduce heat-trapping emissions and adapt to a warmer planet.

  • Los Angeles, Boston, New York City, Baltimore, Mexico City, Toronto, Paris, Berlin, Cape Town and Athens are among those setting strict emissions reduction goals and seeking to adapt to climate hazards like flooding and heatwaves. See the full list here.
  • The U.S. has the most cities on CDP's "A List," followed by Canada and Sweden.

Yes, but: While these cities have set forward-looking goals like lowering carbon emissions by 2050 and using more renewable power for energy consumption, a lot of these actions haven't yet been executed. CDP scores cities on their intent to follow through, which is far from guaranteed.

The big picture: CDP, a London-based nonprofit that asks companies to record their environmental impact, only gave 43 cities an "A" rating in 2018. This year, that figure was bumped up to 105.

  • City-level action to mitigate the effects of climate change is important, but national and international collaboration to cut carbon emissions is even more crucial for sweeping change.

Joe Biden is calling for the winner of November's presidential election to select Ruth Bader Ginsburg's replacement on the Supreme Court.

What he's saying: "[L]et me be clear: The voters should pick the president and the president should pick the justice for the Senate to consider," Biden said. "This was the position the Republican Senate took in 2016 when there were almost 10 months to go before the election. That's the position the United States Senate must take today, and the election's only 46 days off.

President Trump will move within days to nominate his third Supreme Court justice in just three-plus short years — and shape the court for literally decades to come, top Republican sources tell Axios.

Driving the news: Senate Majority Leader Mitch McConnell and Senate Republicans are ready to move to confirm Trump's nominee before Election Day, just 46 days away, setting up one of the most consequential periods of our lifetimes, the sources say.
