|
|
Oxygen, the ratio of its isotopes identifies temperature
|
|
|
Argon, a noble gas that is only present if there is life nearby
|
|
|
Greenhouse gases like carbon dioxide and methane can be directly measured
|
Detailed explanation-1: -As they thaw, carbon trapped within the soils is released into the atmosphere as carbon dioxide and methane. These gases, released to the atmosphere, cause more warming, which then thaws more the frozen soil.
Detailed explanation-2: -Major greenhouse gases include carbon dioxide, methane, nitrous oxide, and various synthetic chemicals. Carbon dioxide is widely reported as the most important anthropogenic greenhouse gas because it currently accounts for the greatest portion of the warming associated with human activities.
Detailed explanation-3: -Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2020, CO2 accounted for about 79% of all U.S. greenhouse gas emissions from human activities.
Detailed explanation-4: -Carbon Dioxide Is Still King. Carbon dioxide is responsible for a third of the total warming of Earth’s climate due to human-produced greenhouse gases.
