Because of the alkaline nature and high calcium content of cements in general, they serve as a CO2- absorbing agent through carbonation processes, resembling silicate weathering in nature. This carbon uptake capacity of ...

Fossil CO2 emissions in 2021 grew an estimated 4.2% (3.5%–4.8%) to 36.2 billion metric tons compared with 2020, pushing global emissions back close to 2019 levels (36.7 Gt CO2).

The uptake of water by atmospheric aerosols has a pronounced effect on particle light scattering properties, which in turn are strongly dependent on the ambient relative humidity (RH). Earth system models need to account ...

Using data from 214 hydropower projects in Norway we study whether investors in renewable energy projects exert discretion about the timing of investment decisions. We know from interviews with these investors that they ...

The effects of aviation on climate pose unique policy challenges. A large fraction of the CO2 emissions (65%) is international and not (explicitly) included in the Paris Agreement. The interpretation of Article 4.1 on ...

While every society can be exposed to heatwaves, some people suffer far less harm and recover more quickly than others from their occurrence. Here we project indicators of global heatwave risk associated with global warming ...

China has been promoting one of the world’s largest campaigns for clean heating renovation since 2017. Here, we present an integrated cost–benefit analysis in a major prefecture-level city by combining a large-scale household ...

Radiative forcing (RF) time series for total ozone from 1850 up to the present day are calculated based on historical simulations of ozone from 10 climate models contributing to the Coupled Model Intercomparison Project ...

Although its per capita carbon emissions are still relatively low, China’s aggregated carbon emissions have grown by nearly 4-fold in the last three decades, and now it is the biggest CO2 emitter in the world. There are ...
