CATHY

Emissions of Asian Anthropogenic Aerosols (A3) are rapidly changing - most notably black carbon and sulphate aerosol precursors from India and China. The resulting range of climate impacts and societal hazards may dominate regionally over greenhouse gas induced trends for the next several decades, but the implications are as yet insufficiently explored. CATHY (Climate implications of rapid changes in Asian Anthropogenic Aerosol emissions: Temperature, Hydrological cycle and variabilitY) tackles the urgent need for quantifying climate related hazards resulting from ongoing and projected changes in A3 emissions.

GRACE - Technical documentation

The model for Global Responses to Anthropogenic Change in the Environment (GRACE) is a multi-sector, multi-regional, recursively dynamic global computable general equilibrium model (CGE) written in GAMS and based on GTAP database. The initial version of the model was developed at CICERO by Aaheim and Rive (2005) for long-term economic analysis of climate change impacts and greenhouse gas abatement policy. It was designed to allow for additional modules for analysis, including emissions permit trading and climate impacts on economic sectors. Coupled with an atmospheric model, the model can also be used for integrated assessment modelling of the climate and economy. Since then several versions have been developed by updating data and certain modules for various studies. Go back to the general introduction.

Natural gas and oil use push up global CO2¬ emissions in 2019, according to latest data

Global CO2 emissions are projected to rise a low 0.6% in 2019 due to robust growth in natural gas and oil use, and despite a decline in coal consumption. Natural gas has been the dominant driver of global emissions since 2012.

Global CO2 emissions rise again in 2018, according to latest data

Global CO2 emissions are on track to rise more than 2% in 2018 on the back of renewed growth in coal use, and continued growth in oil and gas use, according to data released on 5 December.

How cleaner air changes the climate

Aerosols have a strong influence on the present climate, but this influence will likely be reduced over the coming decades as air pollution measures are implemented around the world, writes Bjørn Hallvard Samset in a commentary in Science.

Energy efficiency improvement: Is it reliable for climate mitigation?

Energy efficiency improvement will not dramatically change global energy use and related emissions. However, it might promote economic growth.
