What did Charles David Keeling discover by measuring carbon dioxide in the atmosphere?
Charles David Keeling discovered that: - the concentration of carbon dioxide in atmosphere has an important seasonal variation - after 1960 he discovered that the concentration of carbon dioxide in atmosphere increase year after year, caused very probable by anthropogenic activities
The most common cause of the rise in carbon dioxide concentration from 1960 to 1990 is an increase in what?
An increase in the burning of fossil fuels (coal, oil and natural gas) in industry, travel and to generate electricity.
Why did Willard Frank Libby win The Nobel Prize in Chemistry in 1960?
The Nobel Prize in Chemistry 1960 was awarded to Willard F. Libby for his method to use carbon-14 for age determination in archaeology, geology, geophysics, and other branches of science.
Why are global carbon dioxide levels highest in May and lowest in October each year?
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 See the graph at the link below.
What is happening to greenhouse gases?
Greenhouse gases continue to build up in our atmosphere. Recent measurements for carbon dioxide (CO2) are: Jan 2010: 388 parts per million. Jan 2011: 391 ppm. Jan 2012: 393 ppm. Fifty years ago, in 1960, levels were 318 ppm.

What was the carbon dioxide level in the world fifty years ago?
Carbon dioxide levels in the atmosphere in 1960 were around 315 ppm (parts per million). Levels now (2013) are approaching 400 ppm.
What has been the historical carbon dioxide percentage of air over the past 10 000 years?
From 10 000 BC till 1860, the pre-Industrial Age, the carbon dioxide in air was approximately 278 ppm (0.0278%). In 1900 it was 295 ppm. In 1960 it was 315 ppm. In 1980 it was 335 ppm. In 1990 it was 350 ppm. In 2000 it was 369 ppm. In 2010 it was 388 ppm. In 2011 it was 392 ppm. (March 2011)
Did people drink soda back in the 1960's?
Yes, soda was very popular in the 1960's. Soda was first invented in 1767 by Englishman Joseph Priestley when he infused carbon dioxide with water and created soda water, the first carbonated drink.
The most common cause of the rise in carbon dioxide concentration from 1960 to 1990 is an increase in what?
An increase in the burning of fossil fuels (coal, oil and natural gas) in industry, travel and to generate electricity.
By how much percent has carbon dioxide in the air increased since 1860?
In 1860 the percentage of carbon dioxide in the air was 278 ppm (parts per million), which is 0.0278%. This had been the average figure for the previous 2000 years of the pre-Industrial Age.In 1900 it was 295 ppm.In 1960 it was 315 ppm.In 1980 it was 335 ppm.In 1990 it was 350 ppm.In 2000 it was 369 ppm.In 2010 it was 388 ppm.In 2011 it was 392 ppm. (March 2011)This is an increase of 114 ppm, a 41% increase over the original 1860 amount.
What happened to the carbon dioxide level in 1950?
In 2000 carbon dioxide emissions were 368 ppm (parts per million). This year (2013) they reached 400 ppm. At the beginning of the Industrial Revolution they had been 280 ppm for thousands of years.
Why are carbon dioxide levels decreasing?
Carbon dioxide levels are not decreasing in the atmosphere, in fact, they are increasing. In 1960 levels were 316 ppm. In 1970 levels were 325 ppm. In 1980 levels were 338 ppm. In 1990 levels were 353 ppm. In 2000 levels were 369 ppm. In 2010 levels were 388 ppm. Jan of 2012 levels were 393.09 ppm. As of today we are at 393.68 ppm at Manua Loa.
