Currently en Puerto Rico — 6 de julio, 2023: Mucho más seco

El tiempo, currently.

Aunque el miércoles entró aire mucho más seco detrás de la onda tropical de principios de esta semana, la humedad aumentará gradualmente a niveles normales el jueves y niveles superiores al promedio el viernes. Esto dará como resultado un tiempo más típico del verano, y se espera que los aguaceros sean dispersos el jueves. También ocurrirán tronadas aisladas cada tarde en el oeste de Puerto Rico, junto con aguaceros que se desarrollarán en localidades a favor del viento de las islas locales al este, así como de El Yunque. En otros lugares, los cielos estarán brumosos ya que el polvo del Sahara alcanzará su nivel máximo el jueves por la mañana. Las temperaturas estarán en los rangos alto de los 80 grados y bajo de los 90, y los índices de calor podrían superar los 107 grados en las zonas costeras y urbanas del norte y oeste debido al aumento de la humedad.

What you can do, currently.

The climate emergency doesn’t take the summer off. In fact — as we’ve been reporting — we’re heading into an El Niño that could challenge historical records and is already supercharging weather and climate impacts around the world.

When people understand the weather they are experiencing is caused by climate change it creates a more compelling call to action to do something about it.

If these emails mean something important to you — and more importantly, if the idea of being part of a community that’s building a weather service for the climate emergency means something important to you — please chip in just $5 a month to continue making this service possible.

Thank you!!

What you need to know, currently.

Tuesday was the hottest single day on Earth in the history of human civilization, according to a combination of global satellite data and historical tree ring analysis. One point in far northern Canada was hotter than Miami. In Siberia, the temperature in Altai hit 94°F. Despite July being mid-winter in the Southern Hemisphere, temperatures in Argentina and Chile soared to more than 86°F (30°C). In the Philippines, Metro Manila recorded its hottest-ever July day. The temperature in Iran, Algeria, and Oman all reached 122°F (50°C).

“It hasn’t been this warm since at least 125,000 years ago, which was the previous interglacial,” Paulo Ceppi, a climate scientist at London’s Grantham Institute, told the Washington Post. Given Earth’s annual temperature cycle typically peaks in late July, this is a record that could be broken several more times this month.

The new record comes after June’s global temperature was a shocking 1.46°C above preindustrial levels — just a hair shy of the line-in-the-sand 1.5°C temperature goal agreed to in the Paris Climate Accord, albeit on a monthly basis. Large swaths of every continent and every ocean basis recorded their warmest month on record. Zeke Hausfather, climate scientist at Berkeley Earth told Currently that the new data make 2023 “the odds-on favorite to be the warmest year on record” with about a 77% chance of hitting that mark.

The cause, of course, is climate change driven by fossil fuel burning. Canadian wildfires burning out of control, sharply lower sea ice in the Antarctic, record-setting melt of the Greenland ice sheet, and “scary warm” ocean temperatures all add up to this moment in time being yet another shift-change in the Earth’s climate system.

According to the IPCC, we need "rapid, far-reaching and unprecedented changes in all aspects of society" to stabilize the Earth’s climate system before these kinds of records begin to accelerate. We are in a climate emergency, and you are part of the solution.
