Is there a correlation between CO2 and temperature?
When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.
What is happening to the rate of change for CO2 concentrations and temperature anomaly over time?
What is happening to the rate of change for CO2 concentrations and temperature anomaly over time? [Answer: The rate of change increases. This is another way of saying that if you graphed the results, the slope of the line would become steeper over time.]
What is the relationship between temperature and CO2 concentrations during glacial interglacial cycles?
As ocean temperature was lower during ice ages, it is an obvious first step to consider its effect on atmospheric CO2. The lower temperatures of the glacial ocean would have reduced the con- centration of CO2 in the atmosphere by drawing more of it into the ocean.
Why global temperatures are more erratic than carbon dioxide levels?
Which is the most reasonable hypothesis explaining why global temperatures are more erratic than carbon dioxide levels? Carbon dioxide accumulates in the atmosphere while many factors affect global temperatures.
How does CO2 cause warming?
As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions. About half of that energy goes out into space, and about half of it returns to Earth as heat, contributing to the ‘greenhouse effect. ‘
Why are climate models important to climate scientists?
Climate models are important tools for improving our understanding and predictability of climate behavior on seasonal, annual, decadal, and centennial time scales. Models investigate the degree to which observed climate changes may be due to natural variability, human activity, or a combination of both.
How does carbon dioxide maintain temperatures on Earth?
According to the theory, carbon dioxide controls temperature because the carbon dioxide molecules in the air absorb infrared radiation. The carbon dioxide and other gases in the atmosphere are virtually transparent to the visible radiation that delivers the sun’s energy to the earth.
Why were dust concentrations different during the glacial and interglacial periods?
Dust concentrations were higher during glacial periods, as ocean levels were lower and dried ocean sediments were exposed (and/or wind speeds and hence dust entrainment was greater). In general, anthropogenic changes accelerate temperature changes when compared to glacial/interglacial changes.
Why are there glacial and interglacial periods?
What causes glacial–interglacial cycles? Variations in Earth’s orbit through time have changed the amount of solar radiation Earth receives in each season. Interglacial periods tend to happen during times of more intense summer solar radiation in the Northern Hemisphere.
What causes weather to change?
Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun. What causes weather? These differences in temperature create a restless movement of air and water in great swirling currents to distribute heat energy from the Sun across the planet.
