Human activity has caused the amount of mercury being transported through rivers all over the world to increase up to three-fold since the Industrial Revolution, a new study found. https://t.co/MomOgNF7zR

The last full moon of 2024 is a "Major Lunar Standstill" which only happens once every 18.6 years. This means the moon rises in the its furthest northern position on the horizon and will set in its furthest southern position. Next time this will happen is in 2043. @kcalnews

DT LA reached 102 today, the current forecast has today kicking off a 4 to 5-day long stretch of highs of at least 100 degrees. Since the record began (1877), the longest stretch of 100 or greater T was 8 days long in 1955. If we see 5 days, it will tie the 3rd longest stretch.

[NWS Los Angeles @NWSLosAngeles]

It is currently 96 at Downtown #LosAngeles - and should approach 100 degrees for the day.
Here are some climate tidbits:
Hottest so far in 2024: 97 on Aug 20
Last time it hit 100+: Sept 4, 2022 (it was 103)
The record for Sep 5 is 105 set in 1984.

A whole year of record breaking ocean temperatures.

This warmth has significant effects on ocean ecosystems. A large fraction of the world’s human population rely on protein from the ocean to live. Disruption to life in the ocean does affect us all.

#Diatoms from Thermo-mineral spring do not follow the Species Area Relationships #SAR rule! Check out our new paper in @HYDR_Springer. A nice collaboration with Aude Beauger and @AurlienJamonea1

86 years

In April 1938, @GuyCallendar published his seminal paper showing that Earth’s land areas had warmed over the previous 50 years.

He also suggested that man-made CO₂ emissions had caused around half of the observed warming.

86 years ago.

Long-advertised pattern change has finally arrived in CA, w/waves of mod-heavy showers & isolated t-storms occurring over NorCal as cut-off low taps into subtropical moisture. In fact, between this system & next, it'll be raining more often than not across for next 4 days! #CAwx
