Currently en Puerto Rico — 19 de julio, 2023: Gran nube de polvo del Sahara

El tiempo, currently.

Una capa de aire sahariano llegó a Puerto Rico el martes por la tarde, lo que resultó en que se haya secado la atmósfera para el resto de esta semana laboral. Las partículas de polvo ayudarán a limitar el desarrollo de aguaceros. Sin embargo, se esperan algunas lluvias aisladas o dispersas sobre el oeste de Puerto Rico y en donde el crecimiento vertical de las nubes sobre lugares como Vieques o El Yunque pueden desencadenar aguaceros en algunos puntos de la mitad este. También permanecerá brumoso durante el resto de la semana, lo que reducirá la visibilidad y puede afectar la salud de personas con problemas respiratorios. El calor seguirá siendo una preocupación, especialmente en las zonas costeras urbanas, a pesar de la menor 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!!

Temperatures across the Mediterranean are reaching new all-time highs this week. The latest heat wave will peak on Wednesday, and there’s a chance that southern Sicily could top the all-time European record of 49°C (120°F).

While the headlines are focused on tourists, the real story is the added plight the heat wave is putting on human health and the environment, prompting ‘dramatic’ ecosystem changes and extra stressors for migrants.

Rome recorded the hottest temperature in its long history on Tuesday, 42.9°C (109.1°F). Tunisia reached 48.1°C (119°F) this week — along the dangerous migrant route from Africa to Europe.

The heat wave comes as the EU signed a new deal with Tunisia this week in an attempt to keep more migrants in Tunisia. According to UN data, about 11 children die every week crossing the Mediterranean from Tunisia to Italy. More than 27,000 people died or are missing over the past 10 years trying to get to Europe from Africa. Even more die in north Africa deserts after being abandoned by smugglers with little food or water.

Water temperatures in the Mediterranean Sea are at all-time highs, peaking at 30.4°C (86.7°F) off the coast of Italy, a temperature more typical of the Caribbean, about 20 degrees latitude to the south. All that warm weather is surging humidity across the region, and leaving overnight heat index values in the upper 30s Celsius (90s Fahrenheit) — hot enough to cause deadly heat stroke.

This is what climate change looks like, when so many people seeking a better life are subjected to the violence and injustice of rising temperatures — whether in the Mediterranean or the Rio Grande or in the Himalayas. American poet Amanda Gorman has a new poem this week in the New York Times commemorating the Mediterranean migrants’ plight.
