The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry. [ n 2 ] Over the last 150 years, estimated cumulative emissions from land use and land-use change represent approximately one-third of total cumulative anthropogenic CO 2 ...
The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls.

Greenhouse gas emissions by India are the third largest in the world and the main source is coal. [243] India emitted 2.8 Gt of CO 2eq in 2016 (2.5 including LULUCF ). [ 244 ] [ 245 ] 79% were CO 2 , 14% methane and 5% nitrous oxide . [ 245 ]
Land use change is not included. [1] Annual CO 2 emissions by region. This measures fossil fuel and industry emissions. Land use change is not included. [2] 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 ...
Land use change emissions can be negative. [n 2] [6] In 2023, global GHG emissions reached 53.0 Gt CO 2 eq (without Land Use, land Use Change and Forestry). The 2023 data represent the highest level recorded and experienced an increase of 1.9% or 994 Mt CO 2 eq compared to the levels in 2022.
Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...
The hind feet are larger and have webbing between the toes, and the second innermost toe has a "double nail" used for grooming. [31] [32] Beavers can swim at 8 km/h (5.0 mph); [25] only their webbed hind feet are used to swim, while the front feet fold under the chest. [31]
The Great Barrier Reef is the world's largest coral reef system, [1] [2] composed of over 2,900 individual reefs [3] and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi).
