Global carbon dioxide levels are highest in May and lowest in October.
The Northern Hemisphere has much more land for vegetation to grow on compared to the Southern Hemisphere. Carbon dioxide (CO2) builds up slowly during the northern winter, when trees and plants are dormant. Then in May everything begins to grow, and CO2 is taken out of the atmosphere, so the levels start coming down. In October and November vegetation stops growing, and in its dormant state it stops absorbing CO2, so the carbon in the atmosphere increases. These levels go up and down like this every year.
The readings for 1958, 1959 and 1960 show this:
1960: May: 320.5 ppm: October: 314.5 ppm
1959: May: 320.0 ppm: October: 313.5 ppm
1958: May: 318.0 ppm: October: 313.0 ppm
Ppm means parts per million, so 320 ppm is the same as 0.032 percent (per hundred).
The recent readings for May are:
2011: 394.35 ppm
2010: 393.22 ppm
2009: 390.18 ppm

What else can I help you with?
What area experiences the least amount of seasonal variation?
The equatorial region near the equator experiences the least amount of seasonal variation, as it receives relatively consistent sunlight and temperatures throughout the year. These areas typically have warm temperatures and high levels of rainfall on a consistent basis.
What causes the fluctuation in the level of atmospheric CO2 throughout the year?
The fluctuation in atmospheric CO2 levels throughout the year is primarily caused by the seasonal cycle of plant growth and decay. During the growing season, plants absorb CO2 through photosynthesis, reducing the levels in the atmosphere. In the winter, when plants are dormant and decomposing, CO2 is released back into the atmosphere, leading to an increase in levels.
What describes seasonal changes in the levels of carbon dixode in the atmosphere?
Seasonal changes in carbon dioxide levels are driven by the Earth's natural processes. During the winter, plants go dormant and release less oxygen during photosynthesis, causing carbon dioxide levels to rise. In the spring and summer, plants become active and absorb more carbon dioxide, leading to a decrease in atmospheric levels.
What process is most responsible for the increase in early Earths atmospheric oxygen levels?
The process most responsible for the increase in early Earth's atmospheric oxygen levels is photosynthesis. This is the process by which plants, algae, and some bacteria convert carbon dioxide and sunlight into oxygen and energy. Over time, the accumulation of oxygen from photosynthesis led to the rise in atmospheric oxygen levels.
In what ways have human activities contributed to the increase in atmospheric carbon dioxide levels?
Human activities have increased atmospheric carbon dioxide levels primarily through the burning of fossil fuels for energy, deforestation, and industrial processes.

Would you expect a higher atmospheric pressure at the top of mountain in Alaska's Denali national park or near sea level in Florida's everglades national park?
Since there is more air pressing down from upper levels of the atmosphere, Florida's Everglades park would have the greater atmospheric pressure

What are reasons for natural variation in pH?
The greatest natural cause for change in pH in a stream is the seasonal and daily variation in photosynthesis. Photosynthesis uses up hydrogen molecules, which causes the concentration of hydrogen ions to decrease and therefore the pH to increase. Respiration and decomposition processes lower pH. For this reason, pH is higher during daylight hours and during the growing season, when photosynthesis is at its peak.
What hormone does the pineal gland produce to chemically identify day and season length?
The pineal gland produces melatonin, a hormone that helps regulate circadian rhythms and seasonal biological processes. Melatonin levels typically rise in the dark and fall in light, allowing the body to sense day length and seasonal changes. This regulation plays a crucial role in sleep-wake cycles and reproductive functions in response to varying light conditions.
What effect does increase have on atmospheric levels of carbon?
An increased level of atmospheric carbon can have a massive impact on photosynthesis. It can boost photosynthesis in plants for example.
What process is most responsible for the increase in early Earths atmospheric oxygen levels?
The process most responsible for the increase in early Earth's atmospheric oxygen levels is photosynthesis. This is the process by which plants, algae, and some bacteria convert carbon dioxide and sunlight into oxygen and energy.
