 | | For northwestern South America, monthly mean air temperature records show a warming of 0.5-0.8°C for the last decade of the 20th century (Pabón, 1995a; Pabón et al., 1999; Quintana-Gomez, 1999). |
 | | In several cities in southern and southeastern Brazil, studies on long-term tendencies for air temperature, from the beginning of the 20th century, have indicated warming tendencies (Sansigolo et al., 1992). |
 | | Data since the beginning of the 20th century do not show a clear tendency in mean temperature in the southern cone, but there is a decrease in the thermal range. |
