CO2-emissions from human activities have caused the concentration of carbon dioxide in the Earth’s atmosphere to go up from around 275 parts per million (ppm) before the industrial revolution to over 410 in 2020. A 50 % increase. According to the UN, greenhouse gas concentrations are rising...
Due to anthropogenic emissions, the global CO2 concentration increases at a rate of approximately 2 ppm per year. With over 130 countries and regions committing to carbon neutrality goals and continuously reducing anthropogenic CO2 emissions, understanding how atmospheric CO2 concentrations will...
Carbon dioxide (CO2)is the most important greenhouse gas, and its atmospheric concentration is measured by parts per million (ppm).Methane (CH4)andnitrous oxide (N2O)are also extraordinarily important for the global climate and are measured by parts per billion (ppb). In 2021... ...

(1) for ease of interpretation. Aβof 1 represents direct proportionality between the GPP CO2response and the change in CO2. Note that to avoid undue influence of year-to-year variability in GPP, we estimated GPP(t) and GPP(t0) on the basis of a linear regression fit to the GPP time...
Carbon dioxide (CO2) is the most commonly addressed greenhouse gas, and its atmospheric concentration is measured by parts per million (ppm). Methane (CH4) and nitrous oxide (N2O) are also extraordinarily important for the global climate and are measured by parts per billion (ppb). Carbon di...
We know for a fact that CO2 levels are rising and that human activity is the cause. How do we know this? A simple calculation. Let’s start with the year 1750, generally accepted as the beginning of the Industrial Revolution, when the standard measure for CO2 levels was 278ppm. We’ll...
Estimates of power sector emissions rely on near-real-time hourly or daily electricity data. Figure4ashows that in the first half year of 2020, global CO2emissions from the power sector declined by −5.0% (−341.4 Mt CO2), with a small decline in China (−1.4%, −31.3 Mt CO2) ...

Overall, someone who owned an internal combustion engine vehicle (ICEV) which runs on petrol or diesel created 8.05 tonnes of CO2 or equivalent greenhouse gases per year. Considering that environmental concerns are a major reason for purchasing an electric vehicle you might expect EV owners’ emiss...
