Climate: Past, Present & Future

Ayesha Riaz

Ayesha Riaz is a PhD researcher in Environmental Engineering at the University at Buffalo, State University of New York. Her research focuses on atmospheric remote sensing, with a particular interest in developing methods to observe greenhouse gas emissions from aircraft and satellites. Her current work explores new approaches for detecting and quantifying nitrous oxide (N2O) emissions by combining shortwave and thermal infrared measurements. She is interested in using remote sensing to better understand greenhouse gas emissions and their impacts on the climate.

A Remote Sensing Solution for Nitrous Oxide: The Greenhouse Gas We Need to See Better

Ayesha Riaz October 2, 2026

When we talk about greenhouse gases and climate change, carbon dioxide (CO2) and methane (CH4) usually receive most of the attention. Yet another gas, nitrous oxide (N2O), quietly plays an important role in our changing climate. Commonly known as “laughing gas”, N2O is a powerful greenhouse gas with nearly 273 times the warming potential of …[Read More]

About

Welcome to the blog of the Climate: Past, Present and Future (CL) Division of the European Geosciences Union (EGU). The CL division covers all aspects of the ocean-climate-atmospheric systems, encompassing multiple, overlapping and complementary disciplines. We focus on the reconstruction of past climatic changes, the state of the current climate, and model predictions of future climate scenarios.

Through this blog, we aim to share a wide range of topics in climate science, not only with fellow scientists, but also with anyone interested in learning more about the climate system and its changes. This blog is run with great enthusiasm by our Editors-in-Chief. Everybody is warmly invited to contribute to the blog and submit posts to either Shalenys Bedoya-Valestt, Ceren Moral or Bianca Biess.
