It's all so confusing: CO2 allegedly makes Argentina too wet *and* too dry

Potential Climate Change Side Effect: More Parasites on South American Birds
Newswise — A Wildlife Conservation Society (WCS) study on nesting birds in Argentina finds that increasing temperatures and rainfall—both side effects of climate change in some parts of the world—could be bad for birds of South America, but great for some of their parasites which thrive in warmer and wetter conditions.
Boreal Songbird Initiative : Global Warming and Boreal Birds
Wetlands critical to sustaining North America’s duck populations dot Canada’s Boreal Forest. Twelve to fourteen million ducks depend on this habitat each summer.6 Increasingly seen as rivaling in importance the celebrated “prairie potholes” wetlands (prime breeding grounds for most of the continent’s ducks), vast Boreal Forest breeding grounds could dry up from the high temperatures and drought associated with increasing global warming.
Flashback: Drought a Growing Threat to World Agriculture, Food Production | Global Warming is Real
The droughts in Australia and Argentina, two of the world’s leading agricultural exporters, bring to the fore the the threats a changing climate poses to the security of food supply, not only in those countries, but worldwide.

The study about birds in Argentina was carried out in a 30 hectares area, between September-March of 2007 and 2008, the rainy season. Both the small size and short period of time put the conclusions of the study in a drawer labeled “useless”. Any conclusion that wants to relate the bird population and changes in habits with climate change is utterly invalid.

Then, the report on drought is Argentina, the country where I live, is plagued with misinformation as the ban on wheat exports imposed on February 2010, two full months before the drought commenced in April, caused by the quite natural phenomenon known as La Niña. Until February, the very long El Niño event was in full motion, bringing heavy rains to Argentina. The El Niño rains provided Argentina with an all time crop record of crop area and crop yield.

The ban imposed on wheat export was another episode in the long fight the leftist Kirchner’s government had been indulging in since March 2008 against farmers and cattle ranchers in the country. The farmer’s revolt began when the government tried to raise the export tax on crops from 45% to 90% and to reduce meat exports for trying to keep internal prices down.

Argentina may be one of the few insane countries in the world imposing export taxes on agriculture and meat! All taxes go to fatten the corrupt presidential couple running the country.

The fight with the farmers and ranchers has caused Argentina to lose meat markets worldwide, letting Uruguay –a country 10 times smaller, barely bigger than Buenos Aires province- to gain those markets and export almost twice than Argentina is presently exporting.

Everything is related to politics and nothing to climate change. If any, climate change has been highly beneficial to Argentina farmers and ranchers, and that extends to the rest of the productive areas in the country.
