In 2010 listed as one of the hottest years according to the report State of The Climate newly released The National Oceanic and Atmospheric Administration (NOAA).
The report, compiled 368 scientists from 45 countries were made by recording the 41 indicators of climate for more than four years. Some indicators include temperatures in the lower layer and upper layer of the atmosphere, precipitation, greenhouse gases, humidity, cloud cover, ocean temperature and salinity, sea ice, glaciers, and snow cover.
Some patterns are already known weather cycles do have a significant influence, both on the incidence of weather, and climate during the years of observation. However, a complete analysis of all indicators show long-term trend has been for the last 50 years. This phenomenon is in line with global climate change.
Last year climate oscillations occur also important, such as Oscillation El-Nino Southern Oscillation and the Arctic climate are affecting the region and contributed to many important weather phenomena during 2010.
The following are some indicators of climate in 2010 which led to that year as the hottest year include:
1. Temp. Average annual temperatures in the Arctic continues to increase approximately two-fold.
2. Sea ice and glaciers. Arctic sea ice shrank to a record area of the third smallest in history. Greenland ice shelf was melting with the highest rate since 1958. On the other hand, the average sea ice in Antarctica actually grows until it reaches a maximum record.
3. Sea surface temperature and sea level altitude. Although the La Nina phenomenon takes place in the final half of 2010, the average global sea surface temperature was recorded as the third warmest in history and sea level continues to rise.
4. Salinity in the sea. Oceans become more salty than the average level in areas of high evaporation rate, whereas in areas with high rainfall, sea water feels fresher. This indicates that the higher the water cycle.
5. Greenhouse gases. Greenhouse gas concentrations continue to rise. Carbon dioxide increased to 2.60 ppm, higher than the average annual increase during 1998-2010.
