CO2 emissions - Our World in Data

Growth in emissions was still relatively slow until the mid-20th century. In 1950 the world emitted just over 5 billion tonnes of (CO 2) – about the same as the US, or half of China’s annual emissions today. By 1990 this had quadrupled to 22 billion tonnes.

Simulation of the methane emission in rice fields in China

Abstract: Emissions of the greenhouse gases N 2 O, CO 2 , and CH 4 have increased in the past years. CH 4 has a distinct contribution to global warming and climate change. Rice production plays an important role in CH 4 emission. Thus, the rice fields in China should be considered in assessing CH 4 emission. This study simulated CH 4 emission in rice fields in China during the past 40 years (1971 to 2010) using the denitrification-decomposition (DNDC) model, a process-based biogeochemistryGet price
