What is the relationship between CO2 concentration and global temperature?

When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.

What is the relationship between anthropogenic emissions of CO2 and atmospheric concentrations of CO2?

Anthropogenic emissions of CO2 accelerated at the start of the Industrial Age in the mid-18th century and are now increasing the atmospheric concentration of CO2 by 1–2 parts per million by volume (ppmv) annually [1], a rate of increase that may be unprecedented in recent climate history.

What is the relationship between CO2 concentration and ice age cycles?

In the 1970s, scientists discovered that the concentration of the atmospheric greenhouse gas carbon dioxide (CO2) was about 30\% lower during the ice ages. That prompted theories that the decrease in atmospheric CO2 levels is a key ingredient in the glacial cycles, but the causes of the CO2 change remained unknown.

What is the difference between CO2 emissions and concentrations?

In order to quantify the atmospheric “pollution degree” emissions must be distinguished from concentrations of pollutant matters. A concentration is the amount of pollutant matter in atmosphere per volume unit; it is generally expressed in grams per mc-1 and it is used to express values of air quality.

Who proposed relationship between atmospheric carbon dioxide concentration and temperature?

Arrhenius suggested a doubling of the CO2 concentration would lead to a 5oC temperature rise. He and Thomas Chamberlin calculated that human activities could warm the earth by adding carbon dioxide to the atmosphere.

How do we know that the increasing CO2 in the atmosphere is due to human activities?

Crisp points out that scientists know the increases in carbon dioxide are caused primarily by human activities because carbon produced by burning fossil fuels has a different ratio of heavy-to-light carbon atoms, so it leaves a distinct “fingerprint” that instruments can measure.

Which device is used to measure CO2 concentrations in the air?

carbon dioxide meter
The carbon dioxide meter PCE-AQD 10 is used to measure air quality. The carbon dioxide meter measures carbon dioxide, temperature and humidity. The CO2 sensor from the carbon dioxide meter is disconnected from the main unit with a connection cable.

Which process adds carbon dioxide to the atmosphere?

Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Which of the following processes add carbon dioxide CO2 to the atmosphere *?

Plants add carbon dioxide to the atmosphere during transpiration. Plants remove carbon dioxide from the atmosphere during photosynthesis. Plants remove carbon dioxide from the atmosphere during cellular respiration.
