Plus, El Niño continues to accelerate global temperatures.

The weather, currently.
Tuesday’s temps get warmer
Here comes the sun — and the heat, too. Tuesday will be sunny, and temperatures will rise into the mid-70s. Overnight lows will be around 60. The winds will also calm in the next days.
That said, smoke from wildfires in Canada is blowing back into parts of the U.S. this week as well. Keep an eye on the regional air quality forecasts to monitor how much changing winds could impact the Bay Area.

What you need to know, currently.
New data show that the last week of September was the most anomalously warm week in history. That’s not so surprising given that we’re going into what looks like a very strong El Niño — the tropical Pacific warmth that defines these linked ocean-atmosphere patterns typically starts spreading worldwide during the last four months of the year.
Here’s more, from CarbonBrief:
Global surface temperatures set a new record this week for the highest daily temperature anomalies (departure from the norm) ever observed. They were recorded by a Japanese climate database called the JRA-55 reanalysis product. These were approximately 1C warmer than the 1991-2020 baseline period used by the dataset and around 1.9C warmer than the pre-industrial (1850-1900) temperatures.
As Currently reported last week, these data add to the increasing likelihood that we may already be living in the first 12-month period that’s 1.5°C warmer than pre-industrial levels, and that a few upcoming weeks may top 2°C for the first time ever.
