Currently in Los Angeles — August 16, 2023: Last-ish day of heatwave

The weather, currently.

A warm day across LA yesterday with temps near 90 in many locations. The day did start out with some early marine layer, which dampened temperatures a bit. On Wednesday expect a few additional degrees of warming, before the heat wave starts to ease.

Early next week, we’re looking at another tropical system that may affect the forecast area.

What you need to know, currently.

So far, 2023 has been a year of climate extremes — especially heat.

Global oceans are record-warm, especially those near Florida. All-time records temperatures have been broken in China. We’ve experienced the hottest day on Earth in 125,000 years.

NOAA, NASA, and other global monitoring organizations have crunched the numbers for July and found that we’re now on track for this to be the hottest year in history.

"We now estimate a 99% likelihood that 2023 will set a new record for the warmest annual average," wrote Robert Rohde of Berkeley Earth. That’s a huge boost from their estimate back in January, before El Niño formed, of just a 14% chance of a record warm year.

There’s also now a 20% chance we reach 1.5°C this year — the line-in-the-sand limit agreed to by the world in 2015 in Paris — the point above which widespread climate change could become irreversible on civilization timescales. Though these changes, especially in coral reefs and other critical ecological systems, are already beginning to occur.

Due to a strengthening El Niño, 2024 will be warmer than 2023. Earlier this year, the World Meteorological Organization gave a 66% chance that the world will hit the 1.5°C mark by 2027.

What you can do, currently.

The fires in Maui have struck at the heart of Hawaiian heritage, and if you’d like to support survivors, here are good places to start:

The fires burned through the capital town of the Kingdom of Hawaii, the ancestral and present home to native Hawaiians on their original unceded lands. One of the buildings destroyed was the Na ‘Aikane o Maui cultural center, a gathering place for the Hawaiian community to organize and celebrate.

If you’d like to help the community rebuild and restore the cultural center, a fund has been established that is accepting donations — specify “donation for Na ‘Aikane” on this Venmo link.
