It's official: Last year was the world's second hottest on record, and 2010-2019 was the hottest decade ever recorded.

Why it matters: The findings, published in two separate reports by NOAA and the British weather service the Met Office Wednesday, are in line with those of research group Berkeley Earth, revealed at the start of the year. It's yet more evidence of the long-term warming trend that stems from human-induced greenhouse gas emissions.

A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.
  • The Met Office notes in its report that the main contributor to warming over the past 170 years "is human influence on climate from increasing greenhouse gases in the atmosphere."
The world’s five warmest years have all occurred since 2015 with nine of the 10 warmest years occurring since 2005."
— NOAA statement

The big picture: NOAA notes that analysis by NASA scientists in a separate study just released concurred with its results and found the last decade was the hottest since records began in 1880.

Zoom in: In the United States, 2019 marked the hottest year for Alaska on record.

Zoom out: The average global temperature in 2019 was 1.71°F above the 20th-century average, according to NOAA. The only year to record a hotter global temperature was 2016 — just. That year was 0.07 of a degree Fahrenheit hotter than 2019.

  • "The annual global land and ocean temperature has increased at an average rate of +0.13°F per decade since 1880," NOAA said in its report. However, since 1981 the average rate of increase is more than twice that rate — plus 0.32°F.
  • "For the 21-year span that is considered a reasonable surrogate for pre-industrial conditions (1880–1900), the 2019 global land and ocean temperature was 2.07°F ... above the average," NOAA stated..

The bottom line: Per the Met Office, "The effects of human-induced climate change are not limited to surface temperature. Warming of the climate system is seen across a range of climate indicators that build a holistic picture of change outside of our expectations from natural variability across the land, atmosphere, oceans and ice."

The 2020 election is both very different and very familiar when it comes to the politics of global warming and the stakes of the outcome.

What's new: Democratic voters are more concerned than in prior presidential cycles, polling shows.

Nearly 100 members of Congress members urged Attorney General Merrick Garland to investigate the Justice Department's alleged racial profiling of Asians, according to a letter shared with Axios.

Why it matters: The case of Anming Hu, a scientist who was baselessly targeted in an espionage probe, has renewed scrutiny of the DOJ after an FBI agent admitted to falsely implicating the Chinese Canadian.
