Climate change impacts in Argentina

Climate change impacts in Argentina - what the IPCC 4th Assessment Report has found:
  • Highly unusual extreme weather events were reported, such as flooding in the Argentina Pampas (2000-2002) and hail storm in the Great Buenos Aires area (2006) [TS4.2].
  • Increases in rainfall in southeast the Argentine Pampas have had impacts on land use, crop yields and have increased flood frequency and intensity [TS4.2].
  • Declining trend in precipitation has been observed in southwest Argentina [TS4.2].
  • In the future, sea level rise, weather and climatic variability and extremes modified by global warming are very likely to have impacts on low-lying areas (e.g. province of Buenos Aires coast) [13.4.4].
  • In recent decades, a trend to wetter conditions in parts of southern South America has increased the area inundated by floods, but also has improved crop yields in the Pampas Region of Argentina, and has provided new commercial fishing opportunities [3.5].

Climate Witnesses

WWF runs the Climate Witness programme to collect people's local observations of climate change that are then verified by scientists.

Osvaldo Bonino is a father of 3 and a technical engineer. When the La Picasa lagoon started to expand because of rainfall, in 1997, people thought it was temporary. But the lagoon spread from 10,000 to 30,000 hectares, washing away farms, crops and homes. Many members of the community have had to adapt to the change by switching from farming and agriculture to fishing. For almost seven years, both the national route 7 and the railway have been flooded. Now says Osvaldo, “only the ones who remember us come to Aarón Castellanos”.

Osvaldo spoke at the 10th Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change in Buenos Aires, Argentina, recounting the problem of La Picasa.
