What is the relationship between carbon dioxide and temperature?
The trapped heat energy leads to increased average global surface air temperatures. One reason carbon dioxide has such a big impact on global temperatures is that hotter air can hold more water vapour.
How do greenhouse gases affect Earth’s temperature?
In the case of greenhouse gases, the planet鈥檚 temperature is a balance between how much energy comes in versus how much energy goes out. Ultimately, any increase in the amount of heat-trapping means that the Earth鈥檚 surface gets hotter. (For a more advanced discussion of the thermodynamics involved, check out this NASA page .)
What is the effect of CO2 on the environment?
This means that it causes an effect like the glass in a greenhouse, trapping heat and warming up the inside. This effect is important: without the CO 2 that naturally exists in the atmosphere, Earth might be too cold to support human life.
What would happen if there was no CO2 on Earth?
Without them, the planet鈥檚 average temperature would be below freezing. So we know that even very low, natural levels of carbon dioxide and other greenhouse gases can make a huge difference in Earth鈥檚 climate. Today, CO2 levels are higher than they have been in at least 3 million years.
