Global warming and hurricanes

This talk will present evidence to establish the reality of the following four hypotheses:

1. The global warming we have seen in the last 30 years (~0.3°C) and the last 100 years (~0.5°C) is primarily a result of natural global climate variability resulting from a salinity induced slow-down of the Atlantic thermohaline circulation (THC).

2. The positive water vapor feedback loop in the GCM's anthropogenic CO₂ doubling experiments is incorrect. The water vapor feedback loop is negative. We should expect little human-induced global warming (~0.3°C) from a doubling of CO₂.

3. Global tropical cyclone frequency and intensity is not impacted by global mean temperature changes of less than ± 0.5°C.

4. The large increase in Atlantic hurricane frequency and strength of intensity since 1995 is natural and is a result of the large increase in the Atlantic thermohaline circulation (THC). The large US hurricane destruction of the last two seasons is due primarily to onshore upper-air steering currents.
