Climate change in Argentina

Absolute maximum temperatures recorded in Argentina during the December 2013 heat wave. This heat wave was the longest and the most intense in Argentina.[1]

Climate change is predicted to have significant effects on the living conditions in

Impacts on the natural environment

Mean temperatures have increased by 0.5 °C (0.90 °F) from 1901–2012, which is slightly lower than the global average.

arid areas of the country that depend on it.[4]

Higher temperatures can reduce

snowfall, causing river flow to decrease (less water available), which can reduce hydroelectric energy production; losses of up to 40% had been observed.[3]: 25  Outside Patagonia, mean temperatures have increased at a smaller rate since the increase in minimum temperatures is counteracted by the decrease in maximum temperatures.[3]

The increase in minimum temperatures in much of Argentina outside Patagonia is attributed to the increase in the

greenhouse gases in the atmosphere. The decrease in maximum temperatures is a consequence of higher precipitation, which is associated with higher cloud coverage and evaporation, processes that tend to reduce maximum temperatures north of 40oS.[3]: 89 [5]: 9  In Patagonia, the increase in mean temperatures is higher than the increase in minimum temperatures and is due to the change in atmospheric circulation, not just only the increase in greenhouse effect.[5]

Heat waves, which is defined as 3 consecutive days in which the temperature exceeds the 90th percentile with respect to the 1961–1990 period have become more common and intense between 1961–2010.[1]

Precipitation and extreme weather events

Average precipitation per year in some country

There has been an increase in annual

Buenos Aires province, it has increased by 40%.[3]: 86  The highest increases in the precipitation (from the period 1960–2010) have occurred in the eastern parts of the country.[5]: 15  In contrast, the Andean part of Patagonia along with the Cuyo region has seen a decrease in precipitation, leading to a reduction in river flow in the last 100 years.[5]: 15  Some parts of Patagonia in the Andes have seen a 30%–50% reduction in precipitation since the middle of the 20th century.[1]

Sea level rise

In much of the coastal regions of Argentina, it will not suffer permanent flooding and loss of land associated with

storm surges in coastal areas, including Buenos Aires and a study has suggested that Buenos Aires could be impacted significantly by sea level rise.[1][6]: 67 [3]

Economic impacts

Agriculture

In the last half of the 20th century, the lack of snow at the highest peaks in the Cuyo region has impacted agriculture and viticulture production due to less water available in the rivers (a reduction in 50% of river flow).[7]

Numerous studies have indicated that the productivity of

arid, leading to desertification.[3]: 94  In areas that normally have a dry winter, a higher evaporation would intensify droughts which would disfavor agriculture.[3]

Since the middle of the 20th century, the 600 mm (24 in)

agricultural production is possible had moved more than 100 km (62 mi) to the west, expanding possible agricultural production to these areas.[3]

Although an increase in precipitation will expand agricultural production to the west in areas that were previously too dry and will benefit

regions.[3]

Health impacts

Climate change could extend the

vectors carrying tropical diseases such as malaria spread southwards.[8]

Impacts on housing

Higher temperatures can negatively affect urban areas by affecting the provision of services such as water and energy by increasing the demand for these services.[3]: 94  Heat waves, such as the one in 2013–2014 during the summer could become more frequent and intense.[7] These heat waves can impact agricultural production while in urban areas, it places more demand on energy needs.[3]: 94  Intense precipitation events could become more common, leading to negative consequences.[2]: 33
