Growth in aviation contributes more to global warming than is generally appreciated because of the mix of climate pollutants it generates. Here, we model the CO2 and non-CO2 effects like nitrogen oxide emissions and contrail formation to analyse aviation’s total...
Photovoltaic (PV) solar energy generating capacity has grown by 41 per cent per year since 2009. Energy system projections that mitigate climate change and aid universal energy access show a nearly ten-fold increase in PV solar energy generating capacity by 2040....
China’s 14th Five-Year Plan, for the period 2021–25, presents a real opportunity for China to link its long-term climate goals with its short-to medium-term social and economic development plans. China’s recent commitment to achieving carbon neutrality by...
The IPCC Special Report on 1.5 °C concluded that anthropogenic global warming is determined by cumulative anthropogenic CO2 emissions and the non-CO2 radiative forcing level in the decades prior to peak warming. We quantify this using CO2-forcing-equivalent (CO2-fe)...
After a decade-long search, countries finally agreed on a new climate treaty in 2015. The Paris Agreement has attracted attention both for overcoming years of gridlock and for its novel features. Here, we build on accounts explaining why states reached agreement,...
