BBC Bitesize, [1] also abbreviated to Bitesize, is the BBC's free online study support resource for school-age people in the United Kingdom. It is designed to aid people in both schoolwork and, for older people, exams .
The :)Center for the Study of Carbon Dioxide and Global Change is a 501(c)(3) non-profit organization based in Tempe, Arizona. [1] It is seen as a front group for the fossil fuel industry, and as promoting climate change denial. [2] [3] The Center produces a weekly online newsletter called CO 2 Science.

TCRE is modeled using climate models that simulate carbon emissions by increasing CO 2 emissions by 1% per year from pre-industrial levels until the concentration of CO 2 in the atmosphere is doubled (2 x CO 2) or quadrupled (4 x CO 2).
Carbon-neutral fuel is fuel which produces no net-greenhouse gas emissions or carbon footprint.In practice, this usually means fuels that are made using carbon dioxide (CO 2) as a feedstock.
The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...
Deforestation is a major source of greenhouse gas emissions. A study shows annual carbon emissions (or carbon loss) from tropical deforestation have doubled during the last two decades and continue to increase. (0.97 ±0.16 PgC per year in 2001–2005 to 1.99 ±0.13 PgC per year in 2015–2019) [136] [135]
Jets of liquid carbon dioxide. Liquid carbon dioxide is the liquid state of carbon dioxide (CO 2), which cannot occur under atmospheric pressure.It can only exist at a pressure above 5.1 atm (5.2 bar; 75 psi), under 31.1 °C (88.0 °F) (temperature of critical point) and above −56.6 °C (−69.9 °F) (temperature of triple point).
