Correcting to a reference carbon dioxide content [ edit ] The following equation can be used to correct a measured pollutant concentration in an emitted gas (containing a measured CO 2 content) to an equivalent pollutant concentration in an emitted gas containing a specified reference amount of CO 2 : [ 5 ]
The northern mockingbird is the state bird of Texas. The list of birds of Texas is the official list of species recorded in the U.S. state of Texas according to the Texas Bird Records Committee (TBRC) of the Texas Ornithological Society. As of January 2024, the list contained 664 species. Of them, 170 are considered review species. Eight species were introduced to Texas, two are known to be ...
To convert heat values to joules per mole values, multiply by 44.095 g/mol. To convert densities to moles per liter, multiply by 22.678 cm 3 mol/(L·g). Data obtained from CRC Handbook of Chemistry and Physics , 44th ed. pages 2560–2561, except for critical temperature line (31.1 °C) and temperatures −30 °C and below, which are taken from ...
The selection of state birds began with Kentucky adopting the northern cardinal in 1926. It continued when the legislatures for Alabama , Florida , Maine , Missouri , Oregon , Texas and Wyoming selected their state birds after a campaign was started by the General Federation of Women's Clubs to name official state birds in the 1920s.

For species found in the 50 states, Puerto Rico, and the U.S. Virgin Islands, the taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the list are those of the AOS, the recognized scientific authority on the taxonomy and nomenclature of North and Middle American birds.
Cyanobacteria such as these carry out photosynthesis.Their emergence foreshadowed the evolution of many photosynthetic plants and oxygenated Earth's atmosphere.. Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide, CO 2) to organic compounds.
Climate change has raised the temperature of the Earth by about 1.1 °C (2.0 °F) since the Industrial Revolution.As the extent of future greenhouse gas emissions and mitigation actions determines the climate change scenario taken, warming may increase from present levels by less than 0.4 °C (0.72 °F) with rapid and comprehensive mitigation (the 1.5 °C (2.7 °F) Paris Agreement goal) to ...
