Columbia University, the University of Maryland, and the Smithsonian Institution are working on visual recognition software to help identify species from photographs. Leafsnap is the first in a series of electronic field guides being developed to demonstrate this new technology.

This free mobile app helps identify tree species from photographs of their leaves. Leafsnap currently includes the trees of the Northeast and will soon grow to cover the trees of the entire continental United States.

The realization of Leafsnap was possible thanks to the collaboration between Peter Belhumeur (Columbia University), David Jacobs (University of Maryland), and John Kress (Smithsonian Institution).

The high quality photographs on the website leafsnap.com and in the app were made by the the not-for-profit nature photography group Finding Species.

No, the wildfires in California are not "ideological"

di Jacopo Mengarelli
Pubblicato il 12/01/2025

Rampini from the Corriere includes a series of errors and inaccuracies to support the unbearable rhetoric of “ideology” in the ecological transition and even in climate physics. Contrary to what he claims, the probability and intensity of wildfires are increasing due to the very "human" climate changes. Of course, solutions also involve proper management of vegetation and infrastructure, but this should not overshadow the goal of achieving net-zero emissions. Especially after 2024, which for the first time surpassed an average temperature of 1.5°C.

This topic is also addressed in the guide Extreme Weather Events and Climate Change: A Guide for Journalists, which the Climate Media Center Italia has translated into Italian from the original by World Weather Attribution.
