Question and answer
Q: How do the researchers gather data for worldwide temperatures?
A: From the beginning of the 20th century, when ships started to be equipped with radio, daily weather reporting was a practice for every nation. [ Seafarers are very respectful of the weather and collaborated willingly, even during times of war. A country like Norway, with a very large merchant fleet and remote polar locations like the islands of Spitsbergen and Jan Mayen, were important
participant to this gathering. As you certainly understand, knowing pressure, temperature, etc. for many places is what enables the meteorologist to draw accurate maps of the weather pattern with high and low pressures. Today, it is the World Meteorological Organization (WMO) who gathers all information and makes it available in a standard format to all participating countries. That need to keep a standard reporting system is, of course, as old as meteorology and the weather reports for aviators called METAR, TAF and SIGMET, still use symbols based on what radio officers keyed on their Morse radio set at the beginning of the last century.

User: Does carbon dioxide have an effect on air temperature

Weegy: In the 19th century, scientists realized that gases in the atmosphere cause a "greenhouse effect" which affects the planet's temperature. [ These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice ages of the distant past. At the turn of the century, Svante Arrhenius calculated that emissions from human industry might someday bring a global warming. Other scientists dismissed his idea as faulty. In 1938, G.S. Callendar argued that the level of carbon dioxide was climbing and raising global temperature, but most scientists found his arguments implausible. It was almost by chance that a few researchers in the 1950s discovered that global warming truly was possible. In the early 1960s, C.D. Keeling measured the level of carbon dioxide in the atmosphere: it was rising fast. Researchers began to take an interest, struggling to understand how the level of carbon dioxide had changed in the past, and how the level was influenced by chemical and biological forces. They found that the gas plays a crucial role in climate change, so that the rising level could gravely affect our future. (This essay covers only developments relating directly to carbon dioxide, with a separate essay for Other Greenhouse Gases. ]
