We used to define fire by seasons: they varied from place to place, but there was a period of time that fires were not reliably seen before, and a date they probably wouldn’t be seen after. That is no longer the case, as the destructive fires burning this December in Southern California make clear.

The above chart shows all fires that burned over 300 acres each year from 2000 to 2017 in California, including this months’ blazes.

The future, right now: We tend to talk about extreme weather and fire events as a "glimpse into our future under climate change." But these previously-rare events are increasingly common. "If ‘unexpected’ becomes the norm, because we only talk about extreme weather, how do we change the conversation?" Jeff Rosenfeld, the editor in chief of the bulletin of the American Meteorlogical Society, asked at the American Geophysical Union's annual fall meeting on Wednesday.

The 2017 fire season was one of the worst ever seen across North America:

It's only getting worse: Wildfire seasons are expected to last longer and burn hotter as climate change makes many areas warmer and dryer. "Warmer spring causes earlier snowmelt, [and] warmer summer temperatures can dry out the wood," says Jeffrey Pierce of Colorado State University.

Joint Chiefs Chairman Mark Milley told the Associated Press on Friday that calls with his Chinese counterpart during the final months of Donald Trump's presidency were "perfectly within the duties and responsibilities" of his job.

Why it matters: In his first public comments on the calls that have prompted critics to question whether the general went too far, Milley maintained that such conversations are "routine," per AP.

The consumer's massive "war chest"

Economists expect the pace of economic growth to cool off now that government transfer payments like stimulus checks and emergency unemployment benefits are in the rearview mirror. But evidence suggests that the U.S. consumer is sitting on a lot of financial firepower that could be a key driver of growth in the quarters to come.

Why it matters: U.S. consumer spending is massive, representing about 70% of GDP.

The Fed takes on its own rules amid stock trading controversy

New disclosures that showed Fed officials were active in financial markets set off a firestorm of criticism. Now the Fed may overhaul the long-standing rules that allow those transactions.

Why it matters: What officials actively traded was sensitive to the Fed decisions they helped shape, including the unprecedented support that underpinned a massive financial market boom.
