To mitigate climate warming, many countries have committed to achieve carbon neutrality in
the mid-21st century. Here, we assess the global impacts of changing greenhouse gases …

Methane (CH4), a major component of natural gas, is both a valuable energy source and a
potent greenhouse gas. Due to the remote locations of many CH4 reserves and the …

Agricultural nitrous oxide (N2O) emission reduction strategies are required given the
potency of N2O as a greenhouse gas. However, the growing influence of N2O on …

Overuse of N fertilizers in crops has induced the disruption of the N cycle, triggering the
release of reactive N (Nr) to the environment. Several EU policies have been developed to …

The climate of a terrestrial exoplanet is controlled by the type of host star, the orbital
configuration, and the characteristics of the atmosphere and the surface. Many rocky …

Observed trends in tropospheric ozone, an important air pollutant and short‐lived climate
forcer (SLCF), are estimated using available surface and ozonesonde profile data for 1993 …

This study presents an updated and homogenised ozone time series covering 34 years
(1987–2020) of ozonesonde measurements at Lauder, New Zealand, and attributes …

A global-scale horizontally and vertically resolved ozone climatology provides detailed
insights into ozone variability. Here, the seasonal, annual and decadal monthly Trajectory …

The climate science community aims to improve our understanding of climate change due to
anthropogenic influences on atmospheric composition and the Earth's surface. Yet not all …

This chapter presents our current understanding of global ozone outside of the polar
regions. The increase of ozone-depleting substance (ODS) concentrations caused the large …
