Al Gore also mentions the 50 kilometers of beaches. When he says that, it's implicit that the beaches will be gone with Global Warming. Al Gore should be aware though that the beaches that surround Rio de Janeiro have a history. Copacabana, probably the best known beach in the world, was one of many artificially filled. In the sixties, LNEC was chosen for its enlargement. In the first figure below, you can see how it looked before the intervention. The second picture shows the beach after the intervention. Please notice that not only the beach is bigger, but also the large avenue was introduced. Unlike today, where computer models typically fail, the intervention was done in those days by physical models, with the third picture below depicting the Copacabana model used by LNEC.
Al Gore also claims that Rio de Janeiro experiences extreme flooding and landslides roughly every 20 years. But this is not true. It really occurs every year; indeed, in this Watts Up With That post, earlier this year, Alexandre Aguiar from METSUL, goes back until 1756, and documents a lot of those tragedies. While earlier this year precipitation measured 300 millimeters (12 inches) of rain in just 24 hours, in 1883, on April 26th, 223 millimeters (9 inches) fell in just four hours! Was there Global Warming back then, Mr. Gore? As Aguiar clearly states, it's not Global Warming nor Climate Change the responsible for these annual tragedies; it's human occupation of the land and ridiculous urban planning.
There is expectation that the Gore effect might kick in Rio de Janeiro as well! The rains are not typical of September. The Winter is finishing there, and this has been a very cold season in South America. Evidence is everywhere:
- The driest place on Earth, the Atacama desert in Chile, received a feet of snow
- Bolivia has had the worst snow storms in the last 20 years, leaving thousands of people stranded
- Orangutans have been given blankets and hot soup in Rio de Janeiro's zoo (picture above)
- Soccer tournament "Copa America" started in freezing temperatures earlier this month in Argentina
- The cold snap has killed at least 22 people
