Anchorage, Alaska, saw sizzling temperatures on Thursday, hitting 90ºF degrees and toppling the city's all-time record-high temperature by 5 degrees, as well as the daily record of 77ºF for July 4, according to Weather.com.

Why it matters: The Arctic region has pushed into an entirely new climate. The last 6 years have been the warmest Alaska has experienced since record keeping began in 1952. In addition, Alaska's land-based ice is being lost at a rate of about 14,000 tonnes per second, according to William Colgan, co-author of a report on Arctic climate change in the journal Environmental Research Letters.

Details: A heat dome — or an area of stationary, high pressure — that formed over southern Alaska, is forecast to remain for the next few days, with sweltering heat continuing and then trending northward next week, Weather.com reports.

  • Anchorage's previous all-time record high of 85ºF was set on June 14, 1969.
  • Highs are expected to average 10ºF to 20ºF above normal for this time of the year.
  • Other areas in Alaska have set heat records within the past week.

The big picture: A record-setting heatwave has swept across Europe — a region with some of the longest-kept temperature records in the world. Numerous studies have shown that the odds of extreme heat events, as well as their severity and duration, are dramatically increasing due to human-caused global warming.

Foreign policy will look drastically different if Joe Biden defeats President Trump in November, advisers tell Axios — starting with a Day One announcement that the U.S. is re-entering the Paris Climate Agreement and new global coordination of the coronavirus response.

The big picture: If Trump's presidency started the "America First" era of withdrawal from global alliances, Biden's team says his presidency would be the opposite: a re-engagement with the world and an effort to rebuild those alliances — fast.

Robert Mueller speaks out on Roger Stone commutation

Former special counsel Robert Mueller responded to claims from President Trump and his allies that Roger Stone was a "victim" in the Justice Department's investigation into Russian interference in the 2016 election, writing in a Washington Post op-ed published Saturday: "He remains a convicted felon, and rightly so."

Why it matters: The rare public comments by Mueller come on the heels of President Trump's move to commute the sentence of his longtime associate, who was sentenced in February to 40 months in prison for crimes stemming from the Russia investigation. The controversial decision brought an abrupt end to the possibility of Stone spending time behind bars.
