Currently in Miami — September 28, 2023: Unsettled still
Plus, a new warning that climate change is accelerating.

The weather, currently.
Still wet
The weather will remain unsettled in South Florida through Thursday as winds from the southeast continue to pump in moisture from the tropics. Showers will be numerous with scattered thunderstorms across Miami and Ft Lauderdale. Some may produce heavy rainfall that could cause localized flooding once again in urban areas. Cloud cover will keep temperatures in the upper 80s Thursday afternoon, with overnight lows in the upper 70s. Not much will change over the weekend as moisture will continue to stream in form the Caribbean, although the brunt of the rain activity will likely occur north of Alligator Alley.
El tiempo, actualmente.
El tiempo permanecerá inestable en el sur de Florida hasta el jueves mientras los vientos del sureste continúan bombeando humedad desde los trópicos. Los aguaceros serán numerosos con tormentas eléctricas dispersas en Miami y Ft Lauderdale. Fuertes lluvias podrían causar inundaciones localizadas otra vez para áreas urbanas. La nubosidad mantendrá las temperaturas en el rango alto de los 80 grados el jueves por la tarde, con mínimas nocturnas en el rango alto de los 70. No habrá muchos cambios durante el fin de semana ya que la humedad continuará fluyendo desde el Caribe, aunque el foco de la actividad de lluvia probablemente ocurrirá al norte de Alligator Alley.
What you need to know, currently.
James Hansen, the climate scientist whose 1988 testimony to Congress first made global warming an issue of national concern, has a new warning: Global warming is accelerating.
We’ve all seen the scary charts and maps of this summer of climate extremes. According to data from the first three weeks of September, it’s on track to be the most anomalously warm month we’ve ever measured as a species.
This means that September 2023 will be the most anomalous month in the entire record, building off an already extremely anomalous July and August:

No climate scientist can honestly say they predicted this much warming this quickly, which is why all of us have been reduced to jaw-agape tweeting and comparing notes to figure out what’s happening.
Hansen believes he has narrowed it down to a change in the reflectiveness of clouds, one of the least-known parts of the climate system. Clouds are affected by all sorts of things, including particulate matter and aerosols from the burning of fossil fuels. What’s clear is that the Earth’s Energy Imbalance (EEI) is increasing. The Earth system has little choice but to warm at a faster rate.
“We predict at least a 50 percent increase of the post-2010 global warming rate, compared to the 1970-2010 rate of 0.18°C/decade. This is a partial payment in return for the Faustian bargain that humanity made when it chose to build its economies on fossil fuel energy.”
According to Hansen’s calculations, he concludes "it is now almost certain that the 12-month running mean temperature will exceed 1.5°C by May 2024 or earlier."
We are in a climate emergency.
