Tras 130 años de mediciones directas, el retroceso del glaciar Ventina de Italia se seguirá ahora con drones debido al rápido deshielo y a la inestabilidad del terreno.

Rome

Italy's Ventina Glacier has experienced significant melting attributed to climate change, prompting geologists to switch from on-site measurements to remote monitoring. The Lombardi Glaciological Service now relies on drone imagery to track the glacier's annual retreat, as unstable terrain and debris have made in-person visits too dangerous.

The glacier, which has been monitored since 1895, has lost about 430 meters in the past decade, with nearly half of that loss occurring in recent years. Experts highlight that Italy's alpine glaciers are receding due to insufficient winter snowfall and increasingly hot summers, with the Alps recording temperature increases at twice the global average since pre-industrial times.

Seguimiento a distancia del retroceso del glaciar italiano Ventina

El glaciar Ventina de Italia se ha derretido tanto debido al cambio climático hasta el punto de que los geólogos sólo pueden seguir midiéndolo a distancia. El Servicio Glaciológico Lombardi dice que ahora utilizará imágenes de drones para medir el retroceso anual del glaciar y realizar un seguimiento de su contracción en curso. Los geólogos que han estado midiendo el glaciar in situ durante los últimos 130 años dicen que está lejos demasiado peligroso para futuras visitas en persona. Las simples estacas plantadas en el glaciar como punto de referencia para medir su retroceso son ahora enterradas bajo montones de desprendimientos de rocas y escombros, haciendo que el terreno sea inestable. El glaciar ha estado en constante retroceso desde que los geólogos comenzaron a medirlo por primera vez en 1895. Los expertos afirman que el deshielo se ha acelerado en el iceberg italiano en los últimos años, habiendo perdido unos 430 metros sólo en la última década, casi la mitad desde 2021. Los glaciares italianos se encuentran principalmente en el norte del país, a lo largo de los Alpes y los Dolomitas, debido a las escasas nevadas invernales y a los récords de precipitaciones. veranos calurosos. El Servicio Lombardi afirma que los Alpes representan un punto caliente climático, ya que registran el doble de la temperatura mundial. de aumento de la temperatura desde la era preindustrial, lo que ha provocado una pérdida del 64% de la temperatura media mundial. volumen de los glaciares alpinos.
