| Description: |
Climatologists at the NASA Goddard Institute for Space Studies have found that 2008 was the coolest year since 2000. Since El-Nino is expected to begin soon, a new global surface air temperature record may still be set in the near future, despite the moderate cooling effect of reduced solar irradiance. The Sun is now passing through solar minimum, the low point in its 10- to 12-year cycle of electromagnetic activity. [Source: NASA Earth Observatory]
