Emilio Cuevas-Agulló, a notable Spanish meteorologist, passed away recently after battling pneumonia, marking a great loss for the scientific community engaged in climate research. He was instrumental in establishing the Izaña Observatory as a key site for studying greenhouse gases, particularly carbon dioxide (CO₂), which has seen a dramatic rise in atmospheric concentration over the years, rising from 318 parts per million (ppm) during his birth in 1961 to 430 ppm today. His life's work underscores the urgency of addressing climate change, which is primarily driven by human activity, especially through fossil fuel use.

Throughout his career, Cuevas-Agulló was at the forefront of monitoring changes in greenhouse gas levels, contributing significantly to global climate science. His research was vital not only in measuring the concentration of CO₂ but also in raising awareness about the implications of these changes for the planet. The increase of 35% in CO₂ levels during his lifetime exemplifies the growing climate crisis and the pressing need for interventions to mitigate its effects.

His death serves as a poignant reminder of the challenges faced by scientists worldwide in addressing climate change, as well as the need for continued focus on research and policy to combat this global issue. Cuevas-Agulló's legacy will surely inspire future generations of scientists dedicated to understanding and tackling the climate crisis that threatens our planet's future.
