While the warming atmosphere and higher humidity can provide more energy for these storms, the climate change effects on wind shear, another important element in storm development, is still an active topic of research.
Global warming in the modern era is being driven by increasing concentrations of greenhouse gases in the atmosphere, which leads to an enhanced greenhouse effect.
Thus far, Kepler has found 48 planetary candidates in their host star's habitable zone (of which 10 are near Earth - size), but this number is a decrease from the 54 reported in February 2011 only because the Kepler team is now applying a stricter definition of what constitutes a habitable zone around stars to account for the warming effect of planetary atmospheres, which would move such a zone away from the star, outwards in orbital distance resulting in longer orbital periods (NASA news release; and Kepler Press Conference slides — in pdf).
Such changes are driven in large part by the greenhouse effect, the trapping of greenhouse gases in Earth's atmosphere and consequent warming of the planet.
Re the cost of flying, there are lots of assumptions around because of different ways of using or ignoring a 1999 report on aviation's role in global warming [Aviation and the Global Atmosphere] for the Intergovernmental Panel on Climate Change — the effects of flying are much worse than would be predicted by just burning the oil.
