Penguins.

Gore says “Scientists studying Emperor Penguins at the colony featured in the film “March of the Penguins” found that their numbers have dropped by 70% since the 1960s. The likely culprit: global climate change.”

The hobgoblin here appears to be one of disingenuousness. Although he does not provide a reference for the study he mentions the one below provides some useful insights. The authors point out that there have been breeding failures due to break up of the ice under the colony back in 1974 but if this was an ongoing problem as Al Gore suggests then why has the population been stable since the 1980s?

See Barbraud, C. and H. Weimerskirch. 2001. Emperor penguins and climate change. Nature 411: 184-186.

Some scientists suggest there may well be benefits to ice break shelf break up because of longer coastlines and easier access to food for the penguins.

Sea-level rise.

Gore says “The Thames River, which flows through London, is a tidal river. In recent decades, higher sea levels began to cause more damage during storm surges, so a quarter of a century ago, the city built these barricades that can be closed for protection.”

Again the hobgoblin of disingenuousness. Flooding of London is an old problem dating back to at least the 1200s. Gore presents a graph showing that the annual closures of the Thames barriers have increased in recent years but what he did not say was that the barriers are used as much to keep water in as to keep water out. Also there is evidence that London itself is actually sinking as the British Isles tilts so that sea level would appear to be rising there.

See T.J. Marsh, Indicators of Climate Change in the UK, “The Risk of Tidal Flooding in London

and the U.K. Environment Agency, “The Thames Barrier—a description of flood risks in London.”
