Cop 16 y las Fuertes Inundaciones




Expertos de distintos organismos advirtieron hoy en el marco de la XVI Conferencia de la ONU sobre Cambio Climático (COP16) que el mundo experimentará inundaciones más recurrentes y destructivas en el futuro como consecuencia de la acción humana y no necesariamente por el cambio climático.
Las causas principales del incremento de las inundaciones son la mayor recurrencia de fenómenos hidrometeorológicos y el incremento del nivel del mar, pero también un rápido proceso de urbanización “inadecuado”, y el asentamiento de millones de personas en zonas costeras bajas o áreas inundables.
García indicó que el cambio en los patrones de temperatura y de precipitación como consecuencia del cambio climático no explica “necesariamente” la recurrencia de inundaciones más destructivas, y que hay que analizar más bien la “intervención humana”.

“Estamos descubriendo las coberturas vegetales y boscosas, lo que está afectando tremendamente los sistemas de inundación y de deslizamientos“, dijo.

Es posible que con menores niveles de precipitación promedio en el mundo se tengan mayores niveles de inundación, manifestó.

Asimismo, Avinash Tyagi, experto de la Organización Meteorológica Mundial (OMM), señaló que no hay evidencia científica de que las mayores inundaciones se deban al cambio climático.

Colombia At 200: Surprise Success!




Colombia is a nation that has been to hell and back — and on its bicentennial, has never been better. Its success offers a lesson that should be copied by other states facing similar challenges.

As Americans, it's hard not to be proud of the success of Colombia, our best ally in Latin America, on its July 20 bicentennial celebration.
Just 12 years ago, Colombia was deeply dysfunctional, almost a Somalia — a failed state drowning in blood and close to being taken over by narcoterrorists.

Too strategic to ignore, President Clinton made a last-gasp effort to rescue it through Plan Colombia in 1998.
Contrary to expectation, the country renowned for its massacres, assassinations, kidnappings and cocaine came through. In eight years, its murder rate has tumbled 45%, its kidnappings 90%. The United Nations says it's losing its "crown" as the world's top coca cultivator and cocaine producer. The International Labor Organization has removed it from its watch list of egregious labor violators.

Today, it has the best business environment in Latin America, according to the World Bank. Its stock market is among the world's best-performing. Colombia has taken its place as the "C" in the high-growth CIVETS states.

This year, the country will attract $10 billion in foreign investment, a 400% gain from 2002. The New York Times calls it one of the best places for tourism, and it'll draw more arrivals than any other Latin American country this year.

Meanwhile, the U.S. Department of Homeland Security no longer publishes statistics on how many Colombians are in the U.S. illegally. The number's too small to care. A decade ago, Colombia was the fourth-largest supplier of illegal immigrants to the U.S. Most have now gone home to prosperity.

With crime and narco-terror down and citizens returning, Colombia's model could be valuable, not just to Afghanistan — where Colombian troops are helping out — but to Mexico, whose war is drawing comparisons to Colombia's.

The U.S. commitment was key to success. But the leadership of Colombian President Alvaro Uribe, elected in 2002, was instrumental in the victory.

Uribe called his method "democratic security," but he also paid close attention to private-sector development.
Using that two-pronged approach, Uribe fought his war, with help from the U.S. Unlike Mexico, which often resists direct help from the U.S., Colombia swallowed its pride and accepted direction from U.S. military advisers on its own soil.
