The concentration of carbon dioxide (CO 2) in the atmosphere reached 427 ppm (0.0427%) on a molar basis in 2024, representing 3341 gigatonnes of CO 2. [1] This is an increase of 50% since the start of the Industrial Revolution , up from 280 ppm during the 10,000 years prior to the mid-18th century.

Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
The Integrated Carbon Observation System (ICOS) is a research infrastructure to quantify the greenhouse gas balance of Europe and adjacent regions. In November 2015 it received the international legal status of ERIC ( European Research Infrastructure Consortium ) by decision of the European Commission. [ 1 ]
This is a list of sovereign states and territories by per capita carbon dioxide emissions [n 1] due to certain forms of human activity, based on the EDGAR database created by European Commission. The following table lists the annual per capita CO 2 emissions estimates (in kilotons of CO 2 per year) for the year 2023, as well as the change from ...
In this article, we will take a look at the 15 Countries With The Highest Average Carbon Dioxide Emissions Per Person. You can skip our detailed discussion on the problem of climate change and go ...
(Reuters) -Carbon dioxide emissions from U.S. liquefied natural gas facilities have jumped to 18 million tons per year, up 81% since 2019, adding a volume of greenhouse gas to the atmosphere ...
It is found in the gas state at room temperature and at normally-encountered concentrations it is odorless. As the source of carbon in the carbon cycle, atmospheric CO 2 is the primary carbon source for life on Earth. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas.
