We are on a path of more global warming. But how much your country has warmed and how much it will warm if we keep this trajectory?
In the case of Mexico, it has already warmed 1.5°C (compared to preindustrial levels).

El planeta se está calentando. Ya se calentó y se va a calentar más. Pero qué tanto? Y como se ve por país? Este sitio muestra qué tanto se calentó y cuánto se calentará para el 2100 si seguimos en esa trayectoria.
En el caso de CR, ya se calentó 1.4°C en promedio con respecto a valores preindustriales y todavía le falta. Hay que implementar soluciones YA y rechazar esos intentos de extraer petróleo o gas que pueda tener la administración actual.

Sea surface temperatures (SST) have observed exceptional record warmth over the last few months around the world - August 2023 was effectively off the charts...

Data available from NOAA ERSSTv5 (https://psl.noaa.gov/data/gridded/data.noaa.ersst.v5.html). Methods detailed in https://doi.org/10.1175/JCLI-D-16-0836.1.

Terrible news from a study out today on emperor penguins in the Antarctic (https://www.nature.com/articles/s43247-023-00927-x):

"Of the five breeding sites in the region all but one experienced total breeding failure after sea ice break-up before the start of the fledging period of the 2022 breeding season. This is the first recorded incident of a widespread breeding failure of emperor penguins that is clearly linked with large-scale contractions in sea ice extent."

It has been very dry in #Argentina in the last few years increasing the aridity in the region and stressing agricultural fields.

Increased #Dust and #fire activity are a consequence of this continuous drought as shown in this animation of 20 days of satellite obs over lake Mar Chiquita the most active and voluminous source in the area.

Note the activity occurs with wind from practically any direction and both dust and smoke emission can occur simultaneously.

Starting our account in the Fediverse. We are a group of young scientists from Latin America aiming to promote networking, integrated science and soft skills.

Our main motivation is to understand and explain interactions within atmos-, bios-, cryos- and hydrosphere and how this knowledge can help us to solve the huge socio-environmental challenges we are facing.

In #Argentina this afternoon, major #dust activity in the middle of a dry winter.

#Sunrise over #Patagonia today, with continuous #highlatitudedust activity (posted about it last 2 days) with abundant snow farther south.

This illustrates that dust storms (or more generally, dust activity) can happen in cold weather and during the winter.

‼️Sobrevivir como investigadoras no tendría que ser un acto de equilibrio tan arriesgado y agotador. Toda la sociedad se beneficiaría si las científicas recibieran apoyo para contribuir de forma equitativa al progreso de la ciencia, desde sus formas de hacer y de pensar propias y diferentes.‼️ ✍️ Marta Bueno Saz.

Sunrise in #Patagonia today and there is a very long plume of #highlatitudedust from dry lake Colhué Huapi.

The long plume indicates that activity started during nighttime and it's been active for several hours.

In color is the Aerosol Optical Depth , a proxy of concentration that it is used to derive particle matter amount (dust mass cannot be directly measured from space)

#paleoclimate #biogeochemicalcycles #dust

This morning in #Patagonia, #highlatitudedust activity from several dry lakes (including the large dry bed Colhué Huapi) . Long dust plumes.

The winds are such that dust initially moves east and then veers south making likely this dust will reach the #SouthernOcean and maybe #Antarctica.

This is a good example of dust activity in the middle of the winter (there is even snow not too far south , red circle)

There's very little upside to commenting publicly on the ongoing debate about whether COVID was a lab leak or natural introduction, but I couldn't turn down a request from David Quammen, whose writing I've admired for over 30 years.
