First idea about global warming
The geochemist Charles David Keeling, was the first person to notice, in the 50s, one of the most worrying threats to specialists today: global warming. -
First measurements
Charles David Keeling in 1957 made the precise measurements (Keeling) with which they confirmed that the amount of CO2 accumulated in our atmosphere is increasing. -
Global warming is a real problem
At the end of the 50s, the first measurements of Keeling indicated concentrations of 315 parts per million. Today the figure is over 375 parts per million. -
Break required
Charles had to break the data collection in April 1964: His government funding sources told him that, indeed, 'you have been shown that atmospheric carbon dioxide is increasing, now seeks another interesting research to do'. -
Back to Labol
Charles fought to continue his series of measurements, with the support of many other scientists, and in May 1964 was again collecting data -
The temperature is rising
Since 1979, temperatures on the surface of the earth has risen about twice as fast as the temperatures on the surface of the ocean (0.25 ° C per decade and 0.13 ° C for decade, respectively). -
the greenhouse effect
The greenhouse effect is the process by which absorption and emission of infrared radiation by gases in the atmosphere warms a planet's lower atmosphere and surface. It was proposed by Joseph Fourier -
Hottest year
According to different measurements 1998 was one of the hottest years in history, the land was subject to very high temperature levels caused by global warming. -
National Medal of Science
In 2002, George W. Keeling Bush gave the National Medal of Science, the highest U.S. award dedicated to rewarding the researchers. -
No more ice
It is estimated that reduce snow covered areas and the extent of sea ice, especially in the Arctic, in September 2037 in this area there will be no ice
