The atmospheric concentration of carbon dioxide:

The statement "Atmospheric concentration of greenhouse gases such as carbon dioxide are higher than at any time in earth history", is True.  

Greenhouse Gas:

  • It is a gas that causes the greenhouse effect by both absorbing and emitting radiant energy in the thermal infrared region.
  • Water vapor, carbon dioxide, methane, nitrous oxide, and ozone (O3) are the main greenhouse gases in the Earth's atmosphere.
  • Earth's surface would typically be roughly -18 °C  if greenhouse gases weren't there.
  • In addition to causing respiratory problems from smog and air pollution, greenhouse gas also contribute to climate change by trapping heat. Other consequences of climate change includes extreme weather, interruptions in the food supply, and a rise in wildfires.

Since the start of the industrial period, carbon dioxide concentrations have significantly grown, rising from an annual average of 280 ppm in the late 1700s to 410 ppm in 2019 to an increase of 1.8 ppm over 2021.  

The net emissions of greenhouse gases resulting from human activity rose by 43%. The carbon dioxide emissions, which make up nearly three-fourths of all emissions, rose by 51%. Similar to the United States, the bulk of emissions in the world come from energy production and use, including power generation, transportation, and other energy-related activities.
