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.

Senate action on stimulus bill continues as Dems reach deal on jobless aid

Democratic leaders struck an agreement with Sen. Joe Manchin (D-W.V.) on emergency unemployment insurance late Friday, clearing the way for Senate action on President Biden's $1.9 trillion stimulus package to resume after an hours-long delay.

The state of play: The Senate will now work through votes on a series of amendments that are expected to last overnight into early Saturday morning.

Capitol review panel recommends more police, mobile fencing

A panel appointed by Congress to review security measures at the Capitol is recommending several changes, including mobile fencing and a bigger Capitol police force, to safeguard the area after a riotous mob breached the building on Jan. 6.

Why it matters: Law enforcement officials have warned there could be new plots to attack the area and target lawmakers, including during a speech President Biden is expected to give to a joint session of Congress.

Financial fallout from the Texas deep freeze

Texas has thawed out after an Arctic freeze last month threw the state into a power crisis. But the financial turmoil from power grid shock is just starting to take shape.

Why it matters: In total, electricity companies are billions of dollars short on the post-storm payments they now owe to the state's grid operator. There's no clear path for how they will pay — something being watched closely across the country as extreme weather events become more common.
