## Rubutun asali
The 1997 declaration also updated its citations of evidence that appeared to run contrary to the consensus on global warming. For example, the 1995 declaration cites "observations from earth satellites," where the 1997 declaration cites "observations from both weather satellites and balloon-borne radiosondes." As with satellite data, subsequent analysis of radiosondes has shown a statistically significant warming trend.
