Across the Northern Hemisphere, several regions saw some of the hottest temperatures on record this week, according to information compiled by the Washington Post. Apart from the U.S. and Canada, these temperatures were not the result of one single heat wave, but rather several different weather systems.

Our thought bubble, from Axios Science Editor Andrew Freedman: "July is typically Earth’s hottest month, so heat records falling now is not unexpected. But so many rare milestones being set or tied worldwide does point to the influence of a warming world, given that the link between heat waves and climate change is robust, according to scientific studies."

By the numbers

Hottest recorded temperatures:

  • Yerevan, Armenia: 107.6°, July 2 (tied its previous record high)
  • Denver, Colorado: 105°, June 28 (tied its previous record high)
  • Montreal, Canada: 97.9° Fahrenheit, July 2. The heat is being blamed for 16 deaths in southern Quebec, the CBC reports.
  • Scotland: 91.7°, June 28 (provisional record)
  • Shannon, Ireland: 89.6°, June 28
  • Castlederg, Northern Ireland: 86.4°, June 29
  • Belfast, Northern Ireland: 85.1°, June 28

Snapchat will no longer promote President Trump's account on its "Discover" page of curated content, a spokesperson tells Axios, after Trump tweeted comments that some suggested glorified violence amid racial justice protests.

Why it matters: Snapchat is taking action on the president's account for comments he made elsewhere. That's going farther than other big tech firms and signals a commitment to aligning content served to users with core values, rather than making moderation decisions based narrowly on each post made on its own platform.

Esper catches White House off guard with opposition to military use, photo op

Defense Secretary Mark Esper said at a press briefing Wednesday that he does not support invoking the Insurrection Act, an 1807 law that permits the president to use active-duty troops on U.S. soil, in order to quell protests against racial injustice.

Why it matters: President Trump threatened this week to deploy military forces if state and local governments aren't able to squash violent protests. Axios reported on Wednesday that Trump is backing off the idea for now, but that he hasn't ruled it out.

A leading Chinese gene sequencing and biomedical firm that said it would build a gene bank in Xinjiang is supplying coronavirus tests around the world.

Why it matters: U.S. officials are worried that widespread coronavirus testing may provide an opportunity for state-connected companies to compile massive DNA databases for research as well as genetics-based surveillance.
